evo 9 stock turbo/block 36psi s2 e85 makes how much??
this cannot be right, right?
I did a 4th gear pull after richening some areas that were getting up to 13 AFR
still trying to bring things down to 12 flat, sometimes some pulls gets up to 12.8 still. Almost wondering if I'm starting to run out of fuel... no way though, right?
I am holding 28psi at 6k...
but this has to be wrong. To this date, virtual dyno has been very accurate for me.
whats going on here? does my stock block/turbo really make just under 470hp in 4th?

36psi on stock turbo/motor usually makes a new window, or 2 if you know what your doing.
Why would you be doing 4th gear pulls anyways? On a stock motor and VD none the less. Especially with the load/tq hit your asking for it. If you can't get it dialed in in 3rd it might be time to get alittle help from someone.
FWIW 4th gear always makes more also. Even in virtual land.

Yes those numbers can be very correct, and yes you sure can window your block.
Here is what my car made on 28-29psi on e85 (452/449) it went 11.7 @ 119

Its modded so it can handle about 480WHP modded (depending on health of fuel system & AFR, some can do about 500ish. (I did a lot of before & after comparisons on here with walbro 255's if you dig for the testing) even at 75psi fuel pressure (30psi+ boost on stock regulator) (Bigger injectors may up the number alittle also)
Keep in mind the boost falls off also on a stock turbo. so his total fuel pressure is not that high, which makes the walbro 255 that much more efficient at its job.
Id be more concerned about the crossover downlow with AFR at 3700RPM its 13 AFR with 22psi. that is not what you want. needs to be richer.
I dont know about the numbers so I'm not going to say anything. but lets just say a 420WHP car should trap 120-121 in the 1/4 with ease. (full weight).
