What turbos were you running?

I know what my car did on the dyno at 26 psi, now that i am running 30+ psi the car will easily make 700+whp on e85 and meth.

post the logs....


I dont doubt you made 630 on 93 and meth at 26psi. I do doubt youll be over 700 without PI on e85.

There is a thread on the other forum that actually finds the theoretical *ON PAPER* limit of the HPFP and that is 785hp *CRANK*. This is the everything is perfect in the world number, which does not equate to the real world numbers that have been found. Now with meth as supplementary fueling, you are able to supplement the fuel that the HPFP is giving, but you still arent going to hit that 700whp mark. As far as I know, there hasnt been anyone over 700whp without PI.

Prove me wrong though if you can. If you cant, gtfo

Seems to be about 550whp is the limit. At that level there's no benefit of a single over twins except ease of replacement.

550-600whp is the widely acknowledged limit and you can increase that by a little if you use meth to supplement fueling. This is well documented across the forums despite what some people want to believe.

haven't ran e85 and meth yet on the dyno but i would assume ill be over 730whp easily without port.

E85 has a higher octane, but a lower fueling capacity than 93; which means your hpfp (and lpfp) has to work harder to move the same amount of fuel. You stopped at 548 mostly due to octane. Had you kept going and switched to e85, you would have seen that not much more power could have been made simply because your hpfp will not move much more fuel. Whether or not the amount of octane gained from e85 negates the lack of maximum amount e85 supported by the hpfp is something that would be interesting to know.

Also I'd be weary of moving 90 whp worth of meth through your charge pipe. Cyl 1 is not getting the same as the others due to the stock manifold design.

since you do not know shit about single turbo and yet do not have one ill entertain you.

Yeah Terry told me about that as well i am switching to port methanol soon.

Port meth. How u do dis?

Just meth only.

2 CM10 nozzles 180 degrees from each other.

Still don't see how your keyboard racing has anything at all to do with this thread. My buddy's cousin's rich uncle has a single turbo n54 with 1,300 horsepower. No joke. He posted it online so it must be true.

Notice how your hpfp dips the higher in psi you go? Now when you go to use e85 and try to boost 30psi, your hpfp won't be able to keep up. You won't clear 700 without supplementing the hpfp. If you knew anything, you'd be able to tell from the logs. You need roughly 20-25% more fuel vs 93 when using e85 and your hpfp doesn't have 25% to give.

Also, port methanol would be 6 nozzles porting directly in to each cylinder like a traditional port injection fuel system. If you are going to go through that trouble for meth, just do the actual port injection. What you talk about with 2 nozzles 180 degrees is just dual meth nozzles which is fine for cooling, but still not the best way to fuel.

His fuel pressure looks pretty damn phenomenal to me. But I agree with everything else you are saying...

right, its fine for now while he is spraying meth for fueling and running 93oct on 26-28psi and putting down low to mid 600s. running e85 and pushing 700+ likes hes talking about, changes everything.

[jtswole]

That rail pressure is plenty fine.
