The results !!!!

 

Very nice! Beautiful car! That mph is easily a mid 10 sec car. Get that 60 foot to a 1.6 and you're looking at 10.5s

 

Thanks, yeah that would be Awesome !!! Going to make some adjustments and go for it !!!

 

What sc setup do you have? Is it the vortech centrifugal blower?

 

I have the Rotrex C38 Supercharger with a stage 3 kit on E85 from RR.

 

Oh ok, I figured it was rr, but I forgot they were using rotrex, not vortech. Have you dynoed it? If so, what did it put down?

 

So as of today is this the fastest "charged" isf? What's the fastest naturally aspirated 1/4 mile time?

 

Yeah I had her on the Dyno 2 weeks ago and she put down 650 WHP. I also posted a video "Fire Breathing" ISF Dyno pull.

 

At this point Jason F. in NorCal did a 10.8 something in 1/4 mile at a zero elevation track. AutoClub Dragway is at 1,000+

 

Very nice. How much boost did it make peak? Around 10 psi? I know RR has been keeping alot of these setups on the conservative side for reliability.

 

Yeah she's only making about 10-12 psi.

 

Posting an update on my car. I've added PPE headers, RR Racing intake system & RR Racing tune over the past summer. Also changed the rear tires to 275/30 Indy 500. Hitting low 12s on street tires has been a goal of mine for awhile now. Very fortunate to have achieved that the other day!

 

Did you weigh your car on the scales at Sac Raceway? Would be nice to know along with those really nice time slips!

 

I've never used the scale there before. But I will for sure next time on Feb 8th when I go back. But for reference, I've always gone to Sacramento with 1/4 tank of gas left, no engine covers and no spare tire, tools or trunk mats.

 

Awesome. Would love to know how it fares for weight in street/race trim. I know what mine weighed at Roebling Road, but that was fully loaded with about 1/8 tank of gas.
