I've done some searching and found that a few on the boards had run it with marginal success in a boosted setup. But most of the threads are from 2005 and back. So I'm just curious if any of you stuck around with the product and what you think after all these years?

I've actually been looking for a means of boosting my voltage due to running a large amount of nitrous. Along with the methanol injection it's getting a bit harder for the plugs to ignite the fuel and I've been experiencing strange "break-up" in the higher RPMs. The plugs are NGK Iridium 2-step colder currently gapped at .28. I've tried going lower then that but it would have a hard time around town, which is strange. I would love to be able to run a stock gap with this BAS if it actually works and proves the test of time.

Thanks!

I think people were using some sort of DC to DC step up power supply to feed more than the normal amount of voltage to their coils. I forget what the brand was, but it cost like $50.

I stumbled upon it when I was researching coils and J&S safeguards.

Sorry I can't help more.

Only problem is I have NO idea how this would apply to a VQ35 Altima who has a completely different harness as compared to the 4th gen. That's why I'd rather go with the BAS, but only if it's been proven to be a good product. If not, then I will go with the other options.

Actually I remember reading a thread that you (streetz) were running the BAS at one point? I take it you switched over to the J&S for all that? Or does that not boost voltage?

 

Iv never used the BAS? The J&S is for knock control/timing, dosnt have to do with this at all. Iv only used the DC converter linked above. On an altima I dont see why there would be a difference, you still have a single positive wire powering all the coils. Thats all you need.

 

Must have been someone else then. I do have a wire that is running to a 30AMP fuse under the fuse box near the battery labeled "IGNITION", would that be it?

 

NO!!! lol not that wire!

Your going to have to get the FSM, the wire should be near the battery area, the harness that goes to the coils

 

If that's the case then the wire is actually near the IPDM which is on the other side. Blargh! Time to bust out the FSM again. So it doesn't matter how much voltage is being sent into the unit.. it will send out a constant regular voltage depending on what you set it too, correct?

 

how much nitrous are you spraying?

 

I'm currently jetted to a (crank rated) 130shot. But with the methanol will be going up to a true WHP rated 150 shot. So at the crank that would be 165-170. I've noticed with the meth the car will break up top, but that could also be due to the richness. It's in the mid-10s with the meth where as without it's in the 11s. So I might have some room to just up the nitrous jet and keep the fuel where it is to lean it out some. Liquid bravery = methanol. But would rather have this modification done so that if any other issues arise I'll know that it's not ignition related.

So you get your car back to 100% yet?

 

your problem isn't spark it's the a/f it's too rich on meth, you should not be having these kinda problems at a 150shot at the crank. Try leaning it out the a/f around 11.0-11.5 on meth. I have run large shots with my plugs side gapped around .035 and had no problems with blowout.

Also did you check your coils to see if they're dying

 

Just curious - could you describe your methanol setup? I'm assuming that you are using the water-methanol system - and a lot of it. Any comments are appreciated.

I'm exploring the ways to spray nitrous and straight methanol directly into the nozzles. I did find Jaz junior dragster 1-QT and 2-QT tanks that will fit under my hood, but that still requires a separate methanol-rated fuel pump and regulator.

 

I'm using a DevilsOwn kit which sprays through it's own nozzle controlled by the second stage control on the window switch I'm running. You can run methanol through the nozzle via the solenoid that DevilsOwn sells. I'm using it in place of the scavenge valve because it just feels safer. I've thought about running meth in place of fuel but that might have to wait.

 

LIke someone said you will have to get the FSM for your car, but basically you have to intercept the wire from the ECM, which is located in front of the car on the driver's side. I just went thru this 2-3 weeks ago, I posted many pics and explanation in my N/A thread found here: http://forums.maxima.org/all-motor/5...roject-28.html

This should help you to start.

Yeah, like everyone said, you're running too rich. It's best to keep your afr in the low 12's with spray. My afr was always 12.1 to 12.3 and I never had any "break-up" issues with with a 150-shot and 2-step colder .035" side gapped ngk plugs.

No my car is still running on 5 cylinders, but I just got a new job and I'll be making a lot more money. It should be up and running on 6 cylinders with a direct port 200+ shot within the next month or two.

I want to meet up and go for a ride in your car. I can help you tune it if you want. I may have a smaller fuel jet laying around that will lean it out a bit. Let me know.

 

I wouldnt go all the way to 12afr specially if its only nitrous and no meth, thats pretty lean. In the 10s my car is breaking up, 11's its good, 12 makes the most power but not worth it since its too risky, you make the most power right at the limit before blowing up basically lol. so take it to mid/high 11s

 

I wont be running a 150 shot at 12:1 without the meth. Lol. My friend and I have begun tuning it on the meth and have leaned out the A/F up to the high-10s but weather f'ed us over. Looks like WA is going into it's usual rainy season so I might have to pack up some **** to avoid rust and begin planning for next season. That reminds me, I have to side-gap these plugs soon. I originally had gone with one-step colder side-gapped but thought about why I'd need 'em if I was going to stick with anything under a 100 shot. So I then went with two-step colder Iridiums. I might go with one-step again, but side-gapped for extra insurance.

Now I'm having a really weird problem of the car leaning out in 4th gear. Doesn't happen in any other gear except in fourth. My best guess is fourth being that it's a .9:1 gear is too much load. It takes it way out of the powerband and the engine has to strain a bit to pull. I guess it might be time to go with a '05 6spd swap! The 5spd is just geared too long.

505- a ride might not be too far out of the question. But that really depends on weather now. lol. Once it gets cold, I doubt even the 275s will keep the car from spinning.

 

I used 2 step colder plugs when I ran nitrous but they were too cold for n/a. I do 25miles of stop and go traffic each way to work and did not burn right so I switched back to 1step colder.

Also your car maybe leaning out if you fuel pump can not keep up, with they said which pump are you using.

Last did not car feel any better when you were leaning it out

 

Ive used the KB BAS, and it worked fairly well for me. I boughtthe item used and after a while it would begin to cutout and blow fuses as I reved up into higher RPMs. KB sadi they could repair it for a fee but I decided to use the Laptop adapter mentoned earlier. This seems to be working as well but not enough for me to open the gap back up greatly.

 

It was leaning out on a 130 shot, not the 150. I have yet to really go up to the anything over 140 (to get it up to a real WHP 120 shot) due to the issues. When we were leaning out the car it improved quite a bit, but would intermittently cut up top. It feels almost like small surges, but I know it's not the solenoids, nor the fuel since pressure is at a constant 51PSI. But I think once I get the engine leaned out to around 11.5:1 the lean condition in fourth should go away. You're probably right that it's running way too rich and the fuel pump isn't able to keep up. I have a 190lph waiting for the full blown 150 shot, but that will have to wait till next Spring.

 

Please don't say your running the stock pump, if so swap it asap and your lean condition will go away

Also how did you confirm your fuel psi was holding. Do you have a incabin fuel psi gauge or one sticking out your hood. Cause that's the only way to know for sure

 

The only reason my engine had problems was due to poor nitrous/fuel distribution in the IM. A large shot on a single nozzle setup isn't a really good idea. Making it richer would have been a band aid to the issue. Not a bad idea though. Nitrous motors run best at 12.0:1-12.5:1 afr. I ran the setup for over a year and countless bottles on 92 octane before it ever gave me a problem.

 

iirc, he is running a stock pump.

 

Yup, he is correct.

I'm running an in-cabin electronic fuel pressure gauge. Gotta be safe just in case **** hits the fan. Which it almost did had I not let off.

 

i installed it on a built 350z, it works.

 

get that thing out of there

 

Im thinking about upgrading my ignition. I cant possibly think of any other reason why I am getting misfires. Unless i have to reduce the gap even more, im at .026-.027. I might order another voltage amp since mine didnt produce higher than 12v anymore, or I might look into this Boost A Spark deal, or maybe msd.

 

Hey, streetz, for what it's worth, I was finishing up my dual-nozzle elbow spray tonight, and I remembered to look at my Boosta because it was putting out 18 volts - guess what? Since the switch was covered with shipping tape to keep water out, I couldn't see the switch - and when I peeled it off, the switch was sitting on the 18 volt position. I put a voltmeter on it and it still works right when you change the switch. I left it on 16 volts, warmed up a bottle, and went out to play.

I had jetted both nozzles at 35-shot, and it felt really good on the highway - when I could find an empty spot. Thursday is track day!

 

oh sweet, thats good to know that there arent multiple failures of the device. Ill order another one. Maybe I got water in mine or something.

so 70shot? nice! did you check the plugs after the runs to see how the timing is doing?

 

I didn't check the plugs immediately after the spray test - being on the highway and all that.... I'll pull them tonight and eyeball them, since I'm running on pump gas - 91 octane - at the moment.

I have some under-the-hood pix to post later.
