At 10psi your stock turbo is already spooled. It should jump from 10psi to 25psi without any hesitation.

Or you could just do a boosted launch and you won't have to worry about the turbo spooling.

 

I dont have the finesse for a boosted launch my version of a boosted launch is side stepping the clutch at 3k which my truck doesnt like very well

 

to do a boosted launch on a standard requires using your foot on both the brake and the throttle, while you let out the clutch and slip it til the boost comes up

Never raced a stick, but always wondered if you could build boost on the emergency brake and then release it like a trans brake??

 

The E-brake does not have enough holding ability plus it adds one more thing to remember when launching. Been there, tried that. Myself and Banshee have found that the best 60' times come from wicking the throttle and letting her rip. It takes a LOT of finess to coordinate all those pedals and keep from rolling through the lights and get a good R/T.

I have my N2O set to kick out at 25PSI and the water injection kicks in at 25. You need the N2O from the second you smash it until the turbo lights. Like was said before, the more fuel, the better. You've never seen the PSI gauge move so quick as it does with the N2O spraying.

 

What? You need it the whole time.... come on now.

 

Yeah, you're right. I dont know what I was smoking.

I was thinking of headgasket preservation but who needs those. I plan on doing the gasket removal mod to increase the compression ratio anyway. I think I will also take a dremel to the injector tips to open them up some. Let the fuel fly

 

Dremel is probably one of the best tools made.....

Increase compression...

 

Matego I need to stop looking at your posts your original nitrous post was the only reason I was thinking of getting it. I hate the way my truck low end spools

 

Most guys here would benefit greatly by listening to the above quote.
99% BS, 1% Truth.


What??? Never heard of increasing compression? I want to fill the bowls in the pistons as well to make them flat-tops..... just like the old tree-fittys. I was going to pioneer running the engine on Methanol to be green and since its got 116 octane I can run higher compression. Dont worry, I plan on running some 2 stroke oil to keep the CP3 from seizing tight.

 

Has anybody ever sprayed while sled pulling? I can see the help getting the turbo spooled drag racing but would it really help that much sled pulling? You all ready have the turbo fully spooled when your leave the line. I guess if you wanted to run some huge injectors and then nitrous to burn the extra fuel then i could see the benefit's.

 

I know I could benifit from a little NOS.

Nirtous has been called a turbocharger in a bottle... I have a lot of smoke (unburt fuel) (needs more air) and a small shot of NO2 would probably help me.

I think that if you are running a huge shot, you:
1) need more turbo (s)
2) have a strip/track truck set up for it.

Nitrous is great in the correct application. I know there are a lot of "#2 only!!" people out there, and that's fine with me. If you think drugs are bad, good on you. I think that you use what you can get. If I could use C-4 to fuel my truck, get out of the way!!!3


On the other hand, NO2 will only work if you have extra fuel. Too much NOS is like too much air in a diesel.

Just my .02, I'm no expert.

 

Well tory, how many street rods you see running spray? how many do you see with turbos? Yes the huge injectors is a plus when running the squeeze, you need lots of smoke and yes it helps on smaller sticks to just not as well.

 

I was just kinda wondering if it's that big of advantage or is it more dangerous then it is an advantage? Everywhere has it outlawed but just wondering if anybody does run it at brush pulls? I would be affraid to run it just because if your at a brush pull and it does go boom and your turbo goes out and hurts somebody wow you would be in trouble. I would just like to run it at the strip a few times just to whip up on a few cars? Maybe I'll just leave nitrous to the professionals.

 

Guys usually blow turbos from overspooling them. You have to remember, even though N2O is temporary you still need the supporting mods for that power level. I.E. If you have 650HP w/o N2O and 750 W/N2O you need the turbo flow for 750HP-800 to be on the safe side. Usually its through a external wastegate. The process of complete combustion will send drive pressure through the roof if it cant get out of the manifold. The burnt gasses need to go somewhere, usually through the internally gated turbo and overspools it.

There are many benefits to N2O. You extract all the power from the fuel you are spraying. It also comes out at sub-zero temps which makes your EGT's lower. Unless you are spraying a gross ammount there is no real issue with spraying too much.
