I have run Nitrous for a while now. I put 10-12 bottles through my Stock EJ engine running 11's without issue. Its like anything else. you will have to learn and you will have to tune the system.

When I pulled that engine out it tested perfect on the compression and leak down and sold it. Its still running today. Nitrous does not hurt anything. Detonation and ultimate power output does. I would rather have a small turbo and a 50 shot over a big turbo. Because 80% of the time the smaller turbo will be more fun. When you want to take someone down simply fill the nitrous bottle/add some octane and spray. A 50 shot removes almost 1 full second from your 1/4 mile time and you can Bet it will remove 5 tenths everytime.

The issue is that with a VF30 or larger turbo and nitrous its pretty easy to get carried away and overwork those stock engines. Those rods are weak and they will snap if you produce alot of power. The good thing is they are cheap and you can toss the busted one in the dumpster and slam another one in the car in 3 days work.

The point I want to make when using pump and or limited octane fuels is that often times the limit is the octane and in this case the nitrous is not going to help. You will have to give up boost and timing (power) to make room for the power increase by the nitrous. Spraying on 91 octane is pointless. Spraying on C16 is fun

I'm in Houston. Clark is in Arizona. I'm actually setting up right now in the Texas forum for him to come down here and tune some more cars. If you're interested get with me through PM or something. Clark will definately make power, as long as your motor allows. Like he said, some cars make tons of power, some just don't want too.

Big turkey i believe he is in NY(this is rich right, rsorry only know your sqc name)
Rich Louis and i are also talking to Mike to get him and Clark out to Ny for a second dyno day, if by some chance Tx is closer hit up big T if not hit me up if you are interested.. Probally wont be till early-mid spring, but will be well worth the wait..

I ran a similar setup to an 11.96 with my best trap speeds at 117mph. This was a STG4TMI with NX 50 shot.



I tuned this setup using VP C16 race fuel. It was a great setup and incredibly consistent at the track. As Clark mentioned it's nice to run a smaller turbo with a 50 NX shot as it makes it very easy to launch.

Thanks,
Phil

Yeah but the power drops off hard because of the cams in this motor. That pull was untuned on a dyno day. Its much better now getting full boost in the late 4K range. Manifolds should bring that down. Otherwise I think I will put something small back on like a new 1820 and just spray it with a 75 shot. The car hauls ass now but its just not usable for road racing....

I have been running a 50shot for about a year with a vf22 @17psi on both pump and race gas. I made 316whp w/o no2 tuned very aggressive though. Then made 373whp with 17psi and 50 shot on pump gas. Then used the aggressive nonnitrous map from vividracing for the link and ran c16 and the nitrous and got 412whp with no problems (I'll try digging up dyno sheets for ya, its been about a year). My motor is fine and i've probably went through as many bottles as azscoobie did and my car has held up fine and it rips pretty good, only problem is i had to differ to a rps 6 puc clutch and blew first gear and third. I would worry more about gears than the 2.0L block.

good luck,

your choice

wickedbluwrx,

I was running the VF30.

Clark,

Wow, that is just an unacceptable amount of lag. I agree, I couldn't live with that on a street driven car.

How long did your tranny last? Did it blow right away or after a few bottles?

Moral of the story... Run a stock clutch guys. 400+ whp does not make a stock clutch slip. If it does, replace it, its just worn. You want that cushion to keep the trans together. If anything go to the 30% stronger Exedy sport clutch. Scooby. You must have used Brainstorms dyno right?

I think it would be kind of redundant to run WI w/race gas, I mean Rich you still have a stock bottom end or a whole stock motor for that matter how aggressive do you really want to get? Do a search on WI you'll see that a few people have made great gains with it from pump gas, in some cases as much as 30whp gain. Pretty impressive, and yes tuning with WI from what i can tell it's similar to tuning using race gas. You can run the car leaner, run alittle more boost, or advance the timing a degree or two.

It's not without risk though, read up on it bro.
