I am in fact running 93 octane Valero pump gas... Not the good Shell stuff, but nonetheless it is 93 octane...

550 - I plan to run the ISF at TX2K9 on March 19-22, 2009 here in Houston.

Installed the JZ exhaust Saturday, and I definitely notice the improvement in power. Great numbers but like 550, I am really looking forward to seeing some track times.

+1.....Can't wait for spring to feel the difference Joe's intake and exhaust will make.

I'll probably be running with Peter at the TX2k9. Should be lots of fun.

We will both be at MSR closed track that Thursday. Peter, are you going to be running the F or the Supra at MSR?

Glad to hear you guys are racing soon. We're months away from even thinking about anyting like that up here in the GWN..

Please post up results. It'll help us get thru this cold crap, until we can get our own rides out of hibernation......

Best of luck at the TX2k9 in March.

Anymore dyno runs?

383rwhp what would that equate to the crank? What is the F's drivetrain loss?

Why do you bring this thread back from the grave for the same question that you ask over and over, converting WHP to crank HP. Who cares about crank HP? There is a reason why we all go to dynos, because that's what really matters, what you put to the ground.

Thread over.....

Let's do some stupid math:

Stock IS-F Crank 416HP
HoustonT's Stock IS-F Wheel 357HP
HoustonT's drive train losses 416/357=1.165 = 16.5%

HoustonT's Modded IS-F Wheel 383HP
HoustonT's Modded IS-F Crank (383x1.165) = 446HP

There you go, he got 446HP at the crank

Keep in mind that math is stupid, as you can't really compare the manufacturer crank HP # to a real word dyno #, then you got dyno differences, then car differences...

But hey it is a number but that will answer your question!

I love my JZ exhaust and intake!

Joe is authentic, unlike these other companies that fabricate fake dyno sheets JZ gets his numbers proven by others! I'm curious to DYNO my car now!
