He ran upto 18psi+N20 on his stock VQ30, but recently dropped in a built ~9.4:1 CR VQ35.

It's all in the tuning...

 

I hit the track on sreet tires last night. Traction in 1 & 2 was a joke. I was mainly their to work on the nitrous setup in 3rd and 4th gear. I trapped at 114 with 13psi and 75shot switched on in 3rd and 4th gear only. I only ran one run with out nitrous and ran 104mph, first run of the day and spun through 1st and most of 2nd. Its nice to feel the nitrous hit in 3rd, I would shift into third and floor it, boost comes up and she pulls, then reach over and engage the nitrous and get more pull, very cool.

 

nice nice , got any vids? turn the boooost uppp!!!!! we need to get you a new turbo.

 

time for a bigger turbo matt, if you need a donation let me know.

 

What psi on the no spray run? Sounds like your gettting her figured out.

 

No boost was 17psi, it was a bad run.

I picked up 10gal of 104oct today and topped of the nitrous bottle. IMSTAR is tomorrow at MIR. I cant wait to run 17psi + 75 shot w/ race gas on slicks!

 

Looking forward to comming home from work and seeing the results.

 

i will be the first to bet matt runs tens this weekend! im gonna say 10.95@135mph

 

I doubt a 135 trap speed will happen, but a 10.95 is possible.

 

omg i jsut saw the first video. Matt you are god. I remember seeing you at MIR a while back at the max meet. We all were rolling and and we heard "next we have a Nissan Maxima vs a Mustang, we will see what happens here but i have my money on the mustang." THOUGHT WRONG CHUMP!!! haha we all were standin on the fence to get a good look. you car is amazing. you are my roll model!

 

to trap at 135 in a max i he would need to make about 650-700whp so proboly not ganna happen

to go 10.9 he will probobly need 125-128mph

i doubt he will get a 10 his first day with slicks but maybe ill be presently surprized id just like to see a 125 trap that way at least we know hes making more power with the new setup

 

I don't see why a 135 mph trap is not possible when he runs 20 psi and a 100 shot, for example. Didn't Hal run a 11.9@124.9 mph with boost & juice? That was on a 3.0. Mardi had almost 122 mph with 16.5 psi and a 35 shot on the 3.0, so I'd say 130 mph or so is possible with the 3.5 at 17 psi and a 75 shot. I don't expect his E.T. to be all that since it's a new setup, but the trap speed will tell everything.

You don't need 650-700whp to trap 135 mph. My dad's firebird had 485whp and it trapped 127-131 mph. The weight was around 3000, similar to Mardi's car.

 

Just thought I would say what I have been thinking here......I am surprised these numbers are not better than this. My assumption is that there is somthing go on with this set up.

104mph on 17.5 psi?

113mph on 13 psi and a 75 shot?

Just for comparison. I trapped 111mph on 9 psi with a VQ30. Neal trapped 114mph on 12psi I believe on a VQ30. Mardi shouldn't you be trapping much higher than this?

I just don't see 10's comming from the car how it stands now.

 

I believe he did say he was on street tires dont know how big a difference it would make in the trap

 

OMG, this is killing me!!! I can't view the first video, even though I have it downloaded, and I can't even download the second one. I just get this message: Not Found
The requested URL /~vze4yqyk/12_1atMIR_9_5_05.mpg was not found on this server.
Please help me see these vids...

edit: downloaded many codec's, and finally saw the vid, wow that sounds awesome.
working on viewing the second vid now...

 

He will need a different turbo in able to run 20psi efficiently. It would take a solid 600whp for a Maxima to trap 135+. FYI Hal was making 470+whp when he trapped 124 and that was with a much more efficient turbo and piping setup. You also cannot compare you Dad's Firebird to a Maxima just because the weight is in the same ballpark.

 

Hal trapped 125 with the same power setup that he made 538whp and 603tq. 14.5psi on SP66 with 65 shot NX wet, but he only sprayed in 4th gear. So it was probably making 430-450ish for 3/4 of the run then the numbers posted above for the remaining 2-300 feet. Coming out of the hole spraying on the same setup would surely see 130+.

As far as matt's latest traps I think it's obvious to he and everyone else that something was up with those runs. Street tires can make a slight difference if there is crazy wheelspin but nothing on the order of whatever caused his low traps on his latest runs.

 

please someone tell me how to get the 12.1 video...I can't download it. It says the message in my previous post. "404 Not found" or something like that. Or cansomeone host it somewhere else?

 

Guys, it says Not Found because he (or somebody) took the file down. There's no file with that name there anymore. Just get it from someone who has it on AIM.

 

he said the 104 run was bad and he said he only sprayed in 3rd and 4th on the 113 run so when he sprays in all gears on slicks i would expect it to go up alot

i think 10s could happen with enough spray but definitly not on boost alone with a 60-1 i also think "eventually" hes going to need to ditch the jwt and go with somthing that provides more user configerability and control

 

Who really knows what the "bad run" comment means unless Mardi claifies. If it were a run where a shift was missed or he had to let off before the end then why even include it? I know I wouldn't bother posting a time if the run was not valid. If he maybe just shifted a little early in one gear or shifted really slow then that is not gonna make all that much of a difference.

So if was just a sloppy run, 104mph on 17psi for what mardi has done to this car is not good at all. There has to be a problem.

 

I concur...........

 

what do you call his jwt, emanage blue and j&s combo?

 

add 4psi + spraying ALL gears instead of just 2 + slicks and i think another 20mph is fair to assume. guess we will see

 

im not in a position to put down his setup because it definitly works

obviously i cant bad mouth the J&S because its an awsome peice of electronics but i have reason to believe jwts ignition maps are on the conservative side which could be why his traps are lower than others and i doubt you will find to many 10sec cars with an emanage more or less a pesky "electronic limiting" MAF when speed density is soooo simple yet effective but thats a whole nother ballgame for a whole nother thread and im not about to start spending somone elses money

 

I thought that he was able to advance timing with his blue.

 

what engine managment was hal using when he ran that? just emanage?

 

according to the bottom of page 8 he cant thats why hes not running water/alcy injection but spraying nitous because it speeds up combustion which is like advancing timing but apparently the emanage ultamate should be able to as well as raised revlimiter so he could eleminate the jwt

 

Emanage blue cannot advance timing past whatever it is set at on the ECU.

Subs yes hal only had emanage.

Alk/Water/Meth injection fights detonation and cools the intake charge, enabling you to run more boost. Nitrous on the other hand makes power on it's own by introducing more oxygen than the ambient air has (and also cools to make the charge more dense), so they aren't really used in the same capacity. Alk/water/meth makes it so you can run more boost and/or advance timing to make more power. Nitrous you wouldn't have to make any changes to boost/timing to make more power with of course.

 

Bad means spin through 1st and 2nd. The engine managment issue is a big problem. Standalone or a JWT ECU tuned for my 740s and 100oct would be great.

The clutch wouldnt hold 17psi and the 75shot. It would launch hard but it let go in second. The 50shot and 17psi wouldnt even hold. I had to settle for the 35shot and 17psi. By the time I made it to my last run I had a very auidable exhaust leak on the pressure side. I made the Quick 16 field out of 30+ cars in the Street Renagade Class, 4 or 6 cyl FWD with power adders. I was the 16th qualifier, so I had to race the fastest car in my elimination run, a 10sec full on race Civic. I lost of course but ran a best of 12.0 @ 115.

First off I need a stronger clutch! 26" slicks are also needed. With my 24.5x8's I was pulling consistant 1.7 60's, faster than all full race Civics with 26" slicks, they all were pulling 1.8's. But once we hit second I was toast. I think the lower gearing of a 26" slicks with the power I have would help allot, and improve ET's and traps.

The good news is that the motor held 17psi and the 75shot. But if its not one thing its another. Got the power, need traction. Got traction, need clutch. Got clutch, need bigger slicks.

 

Hey man thats how it always is, our cars when introduced FI are suckubusts, just drain the money right out of our pocket.

 

Mardi, whats the current CR on your engine?

 

I'm sure you'll give that civc a run for its money eventually.

 

Oh he definatley gave that Civic a run for his money!!! The civic ran an 11. flat and matt ran a 12 flat, he was on his tail the whole way through and stayed in him!! The race was definatley a crowd pleaser!! We will have video up of the race soon!!

 

very cool ****

sucks about the clutch i would have never guessed

 

hotness.. time for that big ol turby, some big ol slicks, and a nasty clutch

 

Have you thought about going with an even larger slick like 27" or maybe even 28"? I dont know if a 28" would fit in your wheelwell if your car is lowered at all, but 27" would. Depending on what you end up trapping on a good, clean, all out run a larger than 26" slick might have the benefit of keeping you in a good place in the powerband to cross the line, and also reduce wheelspin off the line even more than just the 26" would. That's why I've been thinking of 27s. I did some testing with cartest and didn't like what 28s were doing to my times, but this was assuming 450whp, I'm sure you will be at even higher whp.

 

Any turbo max at a decent psi is gonna sping through first and second on street tires. My 111mph trap was crazy wheel spin.

 

so who makes a sicker clutch? (so long to the daily driver)

 

Clutchmasters was at the race with a few local sponsor race cars and their trailer. Corey called them today and they were stumped as to how to help me, they are going to call him back.
