What's "flat" about that? I see 160ftlbs at 4000rpm peaking at 211ftlbs. Makes over 200ftlbs for... a touch over 2000rpms.

Cool for track, but flat, it ain't.

OP autocrosses. Centrifugal blowers are worthless for autocrossers.

... worthless for autocrossers, street drivers, spirited twisty drivers, and anyone who ever drives below 75% of their redline. That pretty much only leaves dedicated track cars.

Expected turbo vs super debate.

Instead we got AEM vs Hydra and PD vs centrifugal debates.

Nice numbers David, I bet that car is nuts.

Nicely done!

So have you changed your pulley ratio, or is the extra power just due to E85?

Several things:
* Old dyno results were on a dyno dynamics that the owner fixed the "correction factor" to +20% on, regardless of weather, since he said that got closer to dynojet numbers. I didn't know this until after I last used him. So, likely my old numbers were actually much lower in Dynojet terms.
* Bumped pulley from 125mm->140mm
* E85
