The preload on the drivetrain is a good thing... it'll break fewer parts than hitting a loose drivetrain with power.

With a 20g, and a decent converter, you don't need to help spoolup. I can spool much faster than the tires will allow on a 4-5 psi launch.

Dry spray on a chip that isn't set up to add fuel for it, even for a few seconds, will likely cause reliability issues.

My .02

I second that, Unless you plan on using a Stand alone system to adjust for fuel and or Timming i wouldnt do this. Heres the deal, Parish is already running 1055 HP with out N20 he uses a hell of alot of Meth for boost and like i said N20 is only used to spool the turbos on his truck, And to tell the truth he wouldnt use it at all if he could get a looser Stall Converter.
I am setting my Ty up with a Mega Squirt to run fuel and have also come up with a way to use Coil Packs and a crank sensor so i can Adjust timming on the fly with changing boost and Meth. This is all from Experiance with how this stuff works on similar set ups of how you plan on running it.

So dont take what we say on here as mean or harsh but we are helping with what we know. And even thoe you say just a 30 shot or so figure it like this, With out a set up thats able to change fuel or timming for the N20 you very seriously run the risk of Blowing that motor very quick. So do what you want but be very carefull on how you set it up, A basic computer chip will not be able to control what you want with that set up. So good luck with what your doing.

Re: Nitrous as a turbo lag assistant...?

Thanks DIG, i believe in boost and meth as a route to serious power cause i saw the huge difference the ultimate and meth did from stock.
Still i see there is plenty of meth that could be burnt and a dry system is a way to add oxigen to it with out havin to boost past the adiabatic efficentcy of the 20G, i figure it might be a way to "tune" the alki instead of pulling or adding fuel.
All this is still an idea i have and until i get my truck from the paint shop and do a few datamaster runs and tune it decently to run on boost/alki i wont try it but i already have the systems and will deffinetly have to try it, i posted it to hear your opinions and be aware of things i didnt think about before.
Thank you all that have pointed out details i hadnt considered and or have sugested parts i will need, i truely apreeciate the help.

Doesnt all dry systems have a nitrous regulator that sends a vacuum signal to the FPR to bump up FP from 40s to like 70s?
The one other thing im aware is that the progressive controller wouldnt reinject nitrous gradually every gear change and the alki is progressive but its boost activated, between shifta there could be a window where meth ammounts would drop and nitrous wouldnt.

Re: Nitrous as a turbo lag assistant...?

my advice would be to speak with Nolan. He can set you up with a tune that will allow the meth to work like nitrous in a manner it instantly spools the turbo, while remaining on for cooler intake temps throughout the run. Cleaner A/F, Lower MAT's, More boost, more timing, what more could you want?

If you want my honest opinion, you'd be better off installing the nitrous for show and just not turning the bottle on. You talk about co2 in the intercooler, nitrous, methanol, etc.. throw some propaline oxide in the tank while you're at it. :) Another thing you need to be aware of is when the nitrous hits, your boost will increase and if your wg is not sufficient it will spike all over the place.

Straight up, if you are familiar with nitrous and know to control it, you can make it work. If you dont have a clue, then you may as well just slam the wg and make max boost cause the motor will last just as long.

Lol, propaline oxide. I am familiar with carbs and nitrous but not really with turbos, advanced tunning and electronics. Just some thoughts i wanted to vent and get opinions from people that knows, it is so hard to get advice on this topic sometimes and if you dont ask straight out you hardly ever get specific and constructive information about it and not just here, the supra sites, rx7s and all the forums of cars i've read with this type of systems.

This project means more to me than just me hard headed on wantin to make my truck run with the gas, its a personal project i've been workin on the last year and a half and wanna try and make a patent for it ( i studied mechanics, industrial design and some old school body shop). I was goin to try all this on a 64 Falcon with a boss 302 engine, top loader, 9 in rear end but the costs of the racing parts i needed to finish the car went over de roof, so now im gonna have to do with what i got.

Sincerely, thanks for the advice and if any knows or reads some that might wanna point out, sure or not please feel free to do so. I'll apreciate the help and good intentions.

A 40 to 70 psi change in base would max most in-tank fuel pumps... delivery falls off dramatically as pressure increases. Furthermore, with stock injectors you'd only gain about .3-.4 AFR from the change. You'll be 1.0 to 2.0 lean with the spray, if not more.


Unless you have some mechanism to let the ECM know about the nitrous, you're asking for trouble. I've actually been working on some code to do this, but it's not something ready for public consumption.

In the 14 years I've been dealing with these things, I have yet to see a stock motor survive long-term on spray. It's not a matter of if, but when.
 
Re: Nitrous as a turbo lag assistant...?

it help but remember thai it 2 give u more power and if your motor or tune is not done right it will melt piston

Re: Nitrous as a turbo lag assistant...?

Hey RedTy, all this topic went obsolete for me when I found out SY/TYs came with hyperutectic pistons and they wouldn't melt with nitrous, they would rather shatter with the frecuency nitrous makes when it leans out and pings. That's one of the reasons so many trucks blew up their stock engines and since mine is stock and seems to run very good I wasn't about to tear it up to put forged internals.
