idea of running alcohol and nitrous a good thing?

fst100 · 03-25-2008

just pondering if its a good combination to use nitrous on the grand prix GTP. mods are :
VS Cam, mods for the cam, Progressive Controller w/M2 nozzle, Headers, intake and exhaust and supporting mods. ppl seem to run safely using a wet nitrous setup, but since im running alcohol, would a dry setup be a better choice? also i run an average of 20-24* of timing with various pulleys. the higher the timing on a larger pulley(3.4") and lower timing on say a 3.2" pulley. i dunno how much timing to lower if i run nitrous, wet/dry, but i assume a safe margin to lower would be 16-17*? i want to run the nitrous up top after 2nd gear engages since 1st hear is somewhat pointless with excessive wheelspin. thanks in advance.

I ran the same set up on my GTP it resulted in about a .3 second drop over my wet set up. But I had a 2.8 pully , 3000 stall, DIY shift kit, M10 nozzle, 12.01@117, rockers, TOG headers, 26 degrees timing

, home ported blower, TB, custom dhp with happy nobb, 3" exhaust with cut out and not to much else in mods running pump gas. Oh yeah 100 shot of nitrous activated at 7psi. Still think I had the fastest non-cammed non intercooled, non turbo GTP there was for those mods. Haven't seen anyone beat it yet without a CAM and IC.

Was only able to make two passes before the tranny stated to slip badly but it hit like you got rear ended by a train.

So yes you can run that, I stopped using a wet set up because I use to mix my own race gas adding xylene. Which strips your rotors to a chrome like finish that's why I switched. I keep getting supercharger growl and sure enough rotors were stripped after only 3 months, went through 3 sets on the wet set up.

alright, thanks dvddoc. i can prolly run a 75shot on a dry setup and have it turn on at 7psi and see how it goes up top. i want to stil have my tranny alive though for a bit longer lol

There are a few people doing alcohol for the wet side of a kit on turbobuicks. I tried to get more info on it, but wasn't successful.

that there is damn impressive. sure as hell beat Rob when he had the impala. he was in 11.99 with alcohol and ported manifolds, but he had his own custom grind cam and INTENSE S4 heads. i think without the cam he ran mid 12s.

Yeah my old GTP was one of the fastest mod for mod compared to any other ones I know about on clubgp. Most could not touch those times even with heads and cams.

did the car still run afterwards with 26* of WOT timing?

dvldoc · 06-06-2008

Of course it ran, That was my daily driving set up, zero knock 24/7 on that car, i did also have 42lbs injectors and voltage booster for the fuel pump, The only thing that broke on that car was 3 trannys.

FST100 What have you done as far as nitrous? I can help you if you would like sir. Tell me how much you wanna spray, I would go with a wet kit and did you say your running methanol on the motor already? If so i would use pump gas for the fuel enrichment in the N2O system.Let me know and I will help put you in the right direction and i promise it wont hurt a bit...lol ok maybe your tires and the others you run..

Racer704 · 07-14-2008

I need to explain myself as some of you might think i am wrong in running a wet system but if i read his 1st post right he said he was running alcohol but maybe he was refering to hisW/A set up and i miss understood.

If your running gasoline and no intercooler then the biggest gain you will ever see is runa dry shot with no more timing then you have out all ready and I would start with about 25hp dry shooting it into the throtle bore. Now I know this is a W/A injection site and forum but you will get a bigger gain using your nitrous as an intercooler and a spark knock controler. Water and alcohol wont chill those temps like a -128 shot of cool air. You can double the BHP of the N2O you put in as i have discribed. Now dont go thinking you can add 100 and get 200..lolol See I knew what you all were thinking. If you were to use the proper system and pulse it in you could get away with using a bit more.

Now this is alot like yourDQ system in that you will need to start small and take steps to achieve optimum performance.

But since you do have your system use it and we can look at your options.Knowing what I know now there is only 1 safe system to run and it would be a pulsed system if you can afford it and if not you can add the controler later.

Let me know if i can help
