good to see that in good hands, ( i know who built that )

 

Yes he did - I sure hated to see that car be parted out. Oh, well - you do what you gotta do.

 

With warmer weather, I can get back to this project. Since I had bad luck with direct-port nitrous injection, I'm trying this approach.

EDIT: It looks like Photobucket has "improved" their web site again, and the photos linked on this page may not work. They did work last night, so I dunno what's going on with my Pro account with these yahoos. I'll work on re-linking photos tonight. Bummer....

EDIT: Fixed it - stupid new rules. These are actually in reverse order, but all the pieces are there.










This actually completes the "top-hat" part of this project, where the six Induction Solutions nozzles are aligned with each runner and spray down into the gutted plenum space. Next I need to build two 6-port distribution blocks (may use the existing ones) and make six nitrous and six fuel hoses and the plumbing to attach them to the nozzles. Hopefully the blocks will attach to the UIM so I can get to the plugs easier.

This also means I can start blending E98 from the drum and BP 87-octane to make 20-30 gallons of E85 so I can go play. I got my two polyethelyene measuring "cups" ( 5-qt and 1-qt) to provide a 4+ gal reference mark on a 5-gal jug and a nice drum funnel to pour fuels together.

 

Looks good Harold.

 

It sure is complicated, anyway. I was just outside measuring stuff for re-locating the fuel/nitrous distribution manifolds, and I think they will fit. I'll need to bend and flare a bunch of 3/16" tubing for the 12 connections, but at least I have good bending tools and a great 37* flaring tool. I just might make everything hard lines for nitrous and fuel, cause things will be closer together than before.

 

A few more pix of the final version of the top deck. At first I was going to make the fuel and nitrous distribution manifolds, but I've changed my mind. Today I ordered two Edelbrock 6-port distribution manifolds and the various connectors that will be needed for fuel and nitrous distribution - but I will still make all the hoses. I've learned a few things about hoses. Besides, that fuel block is fugly.








Finally, it's spring - and here is the proof, in my back yard.

 

I wonder how much, if any, of a fuel pressure drop your going to have with those 6 lines coming out from the distribution block? You might need another regulator at the block inlet for desired use pressure and set your primary a few psi higher. Unless you have a separate pump and tank for the fuel (can't recall if you do or not) Anyhow, a separate regulator for the wet nitrous would be nice.
I apologize if you have all that stuff already. Hard to recall everyone's combinations without reading pages and pages of threads. Makes my brain hurt. LOL.

 

You don't have pressure drop unless you have a flow volume close to the entire area of the tube - each tube - and with about .100" tube ID and .022" jets and a real 4AN hose feeding the existing distribution block, that ain't gonna be a problem. I have a Walbro 450 pump in the modded tank with 6AN hoses up and back, and an Aero 1000 hp bypass regulator just before the 6AN lines and Y-splitter going to the 440cc injector rails and huge fuel solenoid. My Cyberdyne digital pressure gauge at the regulator shows no pressure drop while racing and spraying, and that's right in front of my left eyeball. I would probably notice that.

The reason I went to all that trouble is to be darn sure I don't have any fuel pressure drop regardless of what I'm doing, and using E85 means 30% more volume than any gasoline-type fuel. Plus, I still have that Florida surge tank to be installed upstream of the nitrous solenoid inlet.... just in case... just in case I want to run a standing mile with E85 and nitrous.

 

I got a new 2012 Nissan Frontier 4X4 crew cab on Saturday. Now I can pull the trailer and car much easier. Also it just snowed last night.

 

Nice truck! Wouldn't mind getting one of those for myself!

 

I see that there is an optional 6-speed offered...

Getting everything figured out for towing is kinda complicated. Even with the 7-pin trailer towing option, you still gotta have another wiring harness and a Brake Controller installed - to have brakes work. I have those on order today. The new brake controllers work through inertia sensors instead of connecting to the brake pedal. Automatic leveling, brake pressure depends on how fast you stop, and a bunch of other things I never heard of. Even holds on a hill - somehow.

Also, the Nissan hitch receiver is drilled for a hole (used to pin the ball mount) that is different from most other hitches. Lucky me, one came with the truck, but I still gotta figure out how to line up the trailer bulldog socket with whereever the ball winds up - then I gotta run a 30-amp 12 volt service from the battery back to the bumper so I can power up my electric trailer jack. With a car on the deck, that trailer tongue is HEAVY.

 

I think my brain just exploded

 

Ha - this coming from a man who creates turbo maximas at the wave of a welder...


I admit that the new Frontier will take some figuring out, although I researched the trailer brake issues on a Frontier forum and now think I kinda understand what's supposed to happen. I'll find out when I get the braking device and the harness to connect it.

The 4X4 CC Frontier (that's what the Frontier forum calls it) came with a couple of options that I'm still working on: iPod interface (don't have one - maye a stereo input jack?) and Bluetooth with voice recognition. Last night I grabbed my cell phone and jumped into the truck, started it up, and used the controls on the steering wheel and voice prompts from the truck ( !!! ) to connect my phone to the truck and make a test cell call - using just voice recognition. Now it knows my cell when I have it. Way cool...

I also installed the step rails last night. 12 nuts and 12 bolts and that was done.

 

You have my attention!

Looks like a really nice truck. I will be looking into one.
Sounds like it's got some cool tech on board too.

 

My truck is the cheap SV model, but with Bluetooth and Tow and Appearance packages (which has 18" wheels). I went mudding Saturday - OK, took two loads of garden trimmings to the local Forestry recycling place - but it was to the axles in a couple of places, due to the rains we've been having. 4WD works great. Of course, a trip to the spray wash after...

I finished installing the 12 volt power run to the back, for the trailer electric jack, and got that checked out yesterday. Oh, also got the brake controller installed - the truck came with the plug for the adapter cable, so two screws for the mounting bracket, plug-and-click, and it's working with the trailer. Still need to take a test run with the trailer and calibrate the brake.

Now it's back to finishing up the direct-plenum spray project on the Shark.

 

Did some more work this last week... I put an old truck on the trailer and towed it to a recycling yard this morning. The new brake system worked like it was supposed to and the trailer pulled very well. Yea !



Steps on the Frontier:


I finished up the new direct-plenum nitrous system and mounted everything on the UIM. Now I have to wait until the rains stop and then I can switch intake manifolds - again.

 

I found: http://www.importtuner.com/tech/impp...s_and_answers/

 

Yup - that first question is mine - referencing E85 - but the "guru" is way off base. I've never used leaded fuels of any kind in the Shark - and that Bosch sensor was brand new for the testing. His answer don't mean nutin'... You wouldn't believe how many Bosch sensors I've put in the car, all because of questions about how well they were working, and I've never found a bad Bosch yet.

Oh - good job on tracking down the "guru's" response. I filed that question months ago and gave up on a response.

 

I did get all the details taken care of yesterday and today, and finished the complete installation today. I've included a batch of photos because, well, it's complicated and looks like a huge spider in heat.

Finished install of the manifold.





Clearance checks of the final installation. Time for the Dough, Boy!





Really used a slammed hood for these!






Anyway, everything clears the raised-in-the-rear hood with mm to spare.. Good thing - I've got too many little dents in the hood from previous testing. Fuel is the bottom stack and nitrous is the top stack of hoses. The Edelbrock distro blocks are small inside and give very fast response when spraying.

I installed .026N/.020F jets for later testing. I'm gonna go out and OWN some on-ramps tomorrow night. Tonight, it's filets and vino to celebrate. This was one of the more twisted projects I ever did on this Maxima. Nothing like converting my '69 Triumph 850CC cammed injected drag bike to run on methanol/nitromethane, but it's close.

Getting rid of the huge plate that now only holds the solenoids is next, but not immediately important to me.

 

Patiently waiting for feedback on how it drives when sprayed lol.

 

Well, that's kind of you....
When driving the car N/A last night, there was some hesitation on tip-in at 3-4K RPM, in first and second gears. The PLX showed that the lamba didn't go below .93 at WOT, and it should have been .80. I double-checked it this evening and it was the same, so I pulled the MAF to check my secret A/F mod (tape) and it looked normal, but because it was lean, I decided to raise the tape line about 1mm. When I unbolted the MAF from the KramAir ram, the MAF screen fell out to the ground! Since I know that the screen keeps airflow through the MAF moving smoothly, I used some commercial superglue and accelerator to re-attach the screen, and went out for a stroll on the highways. Sonofagun - the N/A lambda at WOT dropped to a consistent 0.77 ! Yea.

Time for a fresh bottle and another trip to my racetrack/interstate, and I found that when spraying that the lambda stayed around .77-.80 while going through three gears while spraying a light shot (dunno where the controller is set but the jets at maximum should be a 150-shot). Tomorrow I'll check the programming in the Maximizer3 and also the TPS voltage going to it at WOT. The orange and blue superbright LEDs were flashing(both solenoids) but there was a lot of off-time during the flashes so not spraying much.

The car pulled good with no surprises but not very hard, but there's a bunch of things to check out. The important thing is that the lambda is where it belongs, so I don't melt down this engine. Now it's just work in debugging the "direct-plenum" spray system.

 

I checked the nitrous controller's programming tonight, and it was set to 40% at 50% throttle and 70% at 100% throttle. This is with 150-shot jetting. I re-programmed the Maximizer3 to start at 50% and go to 100% at 80% throttle, then went out for a ride tonight on my private "track". Wheeee..... the launch is great and spins the 10" M/Ts in first and 2nd gears like before, but - the lambda hangs around 1.2 at WOT. Partial throttle when spraying is about .80 but still no joy at WOT.

Jetting for E85 is a couple of steps richer than the NX recommendiation, and fuel pressure is constant, so nothing weird there. Tank is low after drinking about 3 gallons tonight - in about 10 miles - so of course I'll put another 5 gallons of my personal moonshine in the tank next. I wonder if I need to install the surge tank I got from Kgkeen101 a few months ago. Mount it up front and pipe back to the fuel solenoid for those sudden demands for E85. Dang, I wonder how much E85 I would use at the Texas Mile ??

Probably more to come on this subject...

 

I've been think about this lambda problem - a lot - but I realized today that when I was spraying the previous program (max of 100-shot) the lambda was around .77 - .78 at WOT - and, a fresh 5 gal can of moonshine in the tank, which put me at 1/2 tank on the gauge. Tonight I made a few WOT runs with NA and quit around 1/4 tank. FP showed 42 psi when I parked it.

I put in another can later tonight and went out for a few NA pulls, which worked well and showed lambda of .7x. I came back home and saw the tank had dropped to 3/8 tank and put in another 5 gal of moonshine, up to 1/2 tank, and decided to spray it tonight on the 150-shot program. This time a WOT run gave a .73 lambda through first and second gear (for the first time ever) but power is still Waaay down from the 1.23 lambda pulls. Feels too rich...

This feels like some combination of a low fuel tank and not enough fuel delivered for a 150-shot and plenty of fuel delivered with at least 1/2 tank of fuel. Since I've really re-worked the fuel delivery pump hanger in the tank, it's possible the gauge is wrong - or something else is whacky. My new tank minimum is 1/2 tank.

Since the MAF tape is adjusted to .77 or so WOT NA (rich), and with the fuel jets three sizes larger than what NX says, that could explain the .7x when spraying. If I adjust (retape) the NA lambda back to .85, then set fuel jets back to .018 from .020 and play with that to get about the same total lambda of .85 - .90 I betcha I can whip this.

The car pulls the hardest when lean - I have seen this several times with the 150-shot, and it's a tire-spinning beast at observed 1.2x lambda. More fun to come. Then I can dyno the car.

 

Last night I fine-tuned the tape mod to give me an E85 NA lambda of 0.83 - 0.84 while at WOT. The car pulled well at this "setting". Then I heated up a bottle and went for a drive using the same 26N/20F jet combination and the lambda was around 0.80, and the engine did not pull anything like when the lambda is 1.2x ... TIme for a jetting change, but on the way home getting off the interstate I ran into - and then around - a streetfull of cops making some kind of arrest in front of a Holiday Inn. The NHRA Safety Safari jet dryer truck was parked there (NHRA National are this weekend), so who knows, but I took some back streets to get home. I changed out the fuel jets to .017, but I'll wait untill tonight to make any more runs. I did mix up another 5 gals of moonshine and put that in the tank. My personal street-racer radar was going off because I saw at least eight other sheriff and police cars near my personal on-ramp entrance, so any tests were gonna wait until another day. Maybe I'm closer to a solution.

 

Saturday I drove to the Zarda station in Lawrence with 6 empty 5-gal containers to get some more E85. Filled them all up for nearly $100 - about $3.33 per gallon. Brought everything home then tested what I bought - turned out to be E76. I pumped out 5 gal of E98 and started experimenting with what to add - turned out mixing 4 gal of pump E85 with 1 gal of drum E98 gave me E86, so I used a couple of extra containers to measure out 4 gal of pump E85 and add 1 gal of E98 to it, then transfer to a metal can of racing fuel jug. When all was done, I had 7 5-gal containers of E86 to play with. This was all measured with the Summitt E85 measuring tool and a couple of measuring containers from eBay.

 

lol wish it was that easy

 

good to hear your getting there

your going to the kc street car shoot

 

Slowly I'm figuring out how to deal with E85.... ? There's no drag strip in KC anymore, so maybe you're thinking of the Wichita True Street Shootout on May 04 ? That is one of the events I want to try once the car is 100%. I changed out my empty bottle last night and put in my last full 15lb bottle, but something came up and just got in one NA highway drive. Time to get the other six 15lb bottles re-filled.

Wichita has really stepped up their game since they got a brand-new 1/4 mile strip laid down the first of last year. Take a look...

Wichita KIR link: http://kansasdragway.com/

I still want to turbo my car once the E85 is figured out - I think 20 lbs of boost and E85 with no intracooler would be fun. Any ideas?

I still have a brand-new Holset HE351ve turbo, the one with vanes...

 

^^ let me know if your going on the 4th.
I'll be there if you are.


I'm happy Wichita did something to make up for KCIR closing.

& yes, more powah.

 

Not likely to happen - since May 4 was three weekend ago. Duh.... I guess I need to study the local tracks' schedules.

 

8/31 it is?

 

turbo and nitrous would be fun

not sure about 20psi and no intercooler on e85 maybe 10-12psi

 

I for one eagerly await that one post that begins with "EUREKA!!!!"

Keep up the progress Harold.... The results come.

Andy

 

The engine and transmission are fully built, with measured CR of 10.6, and fuel delivery of at least 800WHP on E85. The engine and transmission are built for at least that much WHP. The question is, how do I get there??

 

That would be "EUREKA in Topeka ! " Har Har... Actually I'm very close to a "final solution" but need some more testing to be sure. It's good to hear the M/Ts scream when banging into 3rd gear again.... and see the lambda stating a constant 0.83...

I think the fuel delivery problem is resolved. Now I need to swap the other UIM back into the car, to test the direct-port injection setup again. I think that manifold will work better than the present direct-plenum manifold, but there's only one way to find out.

 

20psi I'd do air to air or water to air intercooler setup

for track cars with just alittle street time water to air or you could do 10psi and a 100shot seeing how nitrous will cool the charge.

 

Yeah, the big guys seem to use air/water for cooling - not that I'm one of those. I hear they're more efficient, though. You realize that E85 cools pretty darn good, and it does that any time the engine is running. I went to E85 to use heavier nitrous shots without all the damage I used to see, and to lay the groundwork for a turbo burning E85. I've done a couple of stupid things while running nitrous with all E85 and nothing bad happened - on the stock ECU. Heck, the plugs still look great.

Seems like some 350Z headers customized to feed into a big ball-bearing turbo mounted where the battery used to be is now possible to do, right?

 

yeah, the 350z headers is doable. That setup makes 3psi on a 5psi spring on a vq30 free reving. Currently running no intercooler on 93octane.

 

My problem is that I don't know diddly about turbo installations, but I can probably get that work done in Kansas City - lots of performance /tuning shops there.

I'm not quite ready to do it yet - not until I squeeze blood and hair out of the nitrous setup. But someday...

 

yeah, no rush get the nitrous going but I can tell you with the 350z setup a single stage of nitrous will be all you'll need
