Probably more like 400.

I'm making 700 rwhp also, and would never think of putting a shot that big on mine. That's one of those things that's 100x easier said than done.

Rich- I realize there is not much to compare between ethanol (E-85) and methanol. I was just pointing out that there are some nice gains (and benefits) to running methanol vs. leaded race gas (118 octane) and would have to believe on a smaller scale that E-85 would offer some performance gains compared to unleaded premium. I'm looking at this from a purely performance aspect and obviously factoring out the additional fuel consumption/mileage disadvantage that it carries.

One BIG reason why we use E85 is fuel price.
pump gas = 7$/gallon
Race gas = 24$/gallon
E85 = 5$gallon
(E85 is avalible at almost every station)

Aboute 300-400hp N2O shots, Beacuse of the higher octan from pure E85 we will step up to 150hp N2O this season, We will do a test widh 125 first. 300-400 No way, if we need more HP we proberbly go widh a big turbo or two The biggest worries about turbos is lag, since we are race only we need a lot of boost direct from start so if someone have good advice about wich turbo/s or company to choose please write or PM.

I believe that by choosing the right turbo for the application, lag is all but eliminated. Others may post up to help clarify the "lag" issue. A lot of turbo guys here leave on a type of two-step, allowing them to spool up the turbo to some good boost numbers before launching the car and they leave like a rocketship. Hate to think you may "go to the dark side" by switching to a turbo at some point, but if you found the right turbo(s) for your application, I'm sure you would continue to see performance gains.

RPM won't spool up a converter, it has to be under load. This is one reason why all serious drag cars wtih turbos have automatics. They load the motor against the brake to prodice high volume/velocity of exhaust gasses and spool up the turbine. The fastest local turbo car has a godawful huge blower and it takes it about 5 seconds in the pre-stage to get it spooled up. Sounds like a jet warming up. I am not generally a fan of tuirbos (no pun) but that whole procedure is kinda neat.

Yea have sean a lot of turbo cars that have to spoole up in allready in prestage, the problem is that we have a lot of racers that takes advantage of that and do everything to ****up the spool time for them, its real fun to see a non turbo guys waaaaiting to be second in prestage and after that roll in to stage direct, many of the turbo guys makes fine times in the qaulifiction but when its headsup racing theres anotherthing, Its hard to be sucessfull true a 32 car ladder...

Gee, I would never do that

roguedriver is making 808rwhp with a 150 shot, a 300 shot would put him at about 981. that's a lot of power!

Have you ever sprayed a car or had a high HP car? I don't know that even c16 would be enough for that. 300+ shot on top of a blower setup is A LOT.

I run up to a 200hp shot or a bit more with 24psi on 100 octane unleaded with water injection. CR is 7.8:1 though. The heads aren't that great, so the 24psi is a little misleading though.

Lisa33

how much timing widh a 200 shot?

rskrause

22 degrees.

1982z28with18s

I love your posts, because you put in important information like the last line. I doubt you were anywhere near 1000rwhp though either.

rskrause

Only 818 on this run. That's with a 100hp shot, never ran it with 200 on the dyno.

1982z28with18s

You have twin fuel pumps? I knew you made 700+ on the 255/boost a pump, I never knew you stepped it up though.
