my *** 423whp on 10 psi then on top of thats 91 octane gas

you need at less 14-18 psi for 423whp

 

anything is possible....seems a lil high but i doubt its extraordinary

 

let me guess, you did on your special gas mixture in the 91 octane.

 

What manifold? Let me guess a CCfab ramhorn?

 

how big of shot of nitrous?

 

just check out the na forum all his threads are about this special mixture of race gas that's like $45 a gallon so you can run crazy timing.

 

So then its not 91 octane. 91 pump gas??

 

he's using 91 octane pump gas, but will probely say this is how much power i made when i added my special sauce(race mixture). i've never seen a 2.0l with a 35r and 9.0:1 compression make that much whp on 10psi. maybe crank hp. here's one of the na threads https://honda-tech.com/zerothread/2183338
it looks on the dyno sheet like you really only made 400, the graph breakup and peak at the end looks like an error in the graph, causing the inaccurate reading.

423 at 10 psi would be above average power if you were running a GT40.

 

 

thats really only 400hp without the hp/trq spike from where u let off....try reving it a little higher and let of when the power levels off

 

It will be more realistic at 1bar of boost.....

 

seems hard to believe but i call

Which is still above average if you were running a GT40...

 

You can make this much power on 91 octane but it will need more boost than 10psi

yea.. 1 bar will make that power no problem with 91 octane...

but not with 10 psi... and it is just a spike

 

spool looks kind of lazy for a 35r. My 42r spools almost the same.

 

also i would like to see the log, just because it has a 10psi wg spring doesnt mean its making 10psi

 

i was thinking the same thing... from 3k-6k it looks like my 72mm turbonetics......

no this has nothing to do with the soysauce gas
this is a true 91 octane car....

why don't you explain it then?

Looks like a manipulated dyno to me...

It can't be fuel, because your timing would be CRANKED...and your spool wouldn't be so slow.

Can we get a video, and perhaps a dyno graph without all the breaking up?
