Youll be just above 400 since you have S2's. Im on E85 with the same turbo and less mods and im sitting around 475 @ 28psi.

I just don't understand how some members on these forums post how their evo 8 or 9 is making around 520whp and 480wtq on 91 oct with a stock block and only a few modifications. Is there something I'm missing?

They are at sea level and not in Denver for starters,

evoniners

I get the whole sea level thing but I'm pretty sure it won't make that big of a difference.

evostanman

I wouldn't say a few modifications for 520WHP.

All basic bolt ons + E85 + turbo upgrade + good tune = 500whp or way more on stock block.

It's the tune that makes the difference.

mavraolan

480wtq on stock block with 91 i don't think so you may make 500whp with aggressive tune on that turbo, on s3's plus aftermarket inlet and exhaust manifold and tb but tq will never be more than 390 in stock block....unless u want to brake it.

im making 370 stock turbo and block. All i got done to it is a map o2 dump, intercooler and short route intercooler piping. Thats also at 25lbs

Sea level to 6200 ft assuming DA is relatively close is 9% loss in and of itself. In June of 2016 when we were in Springs it was 10000 ft DA and we were down more like 11-12%.

You didnt say it but by your mods you have a stock appearing GTX3071 not a full kit? That will further hinder power. I have done 425 on the ATP GTX3071 on an 8/9 with S2s and that was kind of on the push. Backpressure becomes an issue with that housing.

Those are pretty good numbers for a stock turbo and block.

After all that work and a good time you'll be so happy with the car you don't car about the numbers. But sounds like you want 400+ to the wheels?
