Autoweek's Vishnu article is now online
 

I didn't see a post here yet, so here goes:

my question to Shiv: is the 310 hp claim on 91 or 93 octane gas?

In the future, when I have learned the Evo 100% - Vishnu is probably going to be the way I'll go. I've always been a fan and their WRX numbers pretty much say it all

310 hp with a catback exhaust and computer tuning. Not bad! :)

that almosst like the FQ 320 package that we dont get here in the US

Ah...it's called the FQ300 unless you are reffering to the extreme 330 package on sale in england that refers to 330 ft/lb of torque and has 320hp?

actually it's the FQ305 for the Evo 8 - at least according to Top Gear....

FQ 300 is 300 lbs/ft and 305 BHP

EVO VIII Xtreme is 320 lbs/ft and 337 BHP

EVO VIII Xtreme 2.3Ltr is 400 lbs/ft and 340BHP

I heard Vishnu is making a Stage 1 with a turbo back exhaust.

To tell the truth, I despite talking in crank horsepower terms since we can't read that with a chassis dyno. Trying to derive crank hp from wheel hp is always going to be a grey area as far as accuracy is concerned. But no one wants to hear that our Stage Zero kits puts down only 215 wheel hp (eventhough stock cars are putting down 185-190 unders identical testing conditions). All on 91 octane.

That said, I suspect 310 flywheel hp is reasonably accurate for 91 octane. 93-94 octane should be good for another 10-15 hp but I won't know for sure until next weekend's East Coast dyno tuning trip. In-house testing from gas mixing does seem to suggest this being the case. We'll see soon enough.

As for Stage One, it is undetermined whether it will simply be a Stage Zero plus downpipe (and a remapped XEDE program, of course). It may include another hard part if testing continues to go smoothly. It's a bit too early to make any promises at this point. We're not in the business of slapping on parts as soon as possible and sending them out the door :)

Cheers,
shiv

Hi shiv. :) I know you can't give any details about the horsepower problems that you discovered in a few Evos (if there is indeed a problem), but do you know how much longer until the issue is resolved? Since it is in Mitsu's hands right now, when will the consumer actually hear something from Mitsu? Has Mitsu given you any idea? Thanks.

Sorry for going a bit off-topic ;)
