Super impressive! I would never have guessed that the ISF would be capable of hitting 190 in 1.5 miles!

i have no idea where that torque limit claim comes from. These trannies are bulletproof. We have yet to see a single failure on a supercharged ISF, RCF, or GSF.

Actually Clayton’s car was running 91 octane with a can of octane booster.... but our e45 tune will easily make 50hp more. Additionally, at an event like reducing drag can really improve the trap speed, so removal of side mirrors, taping off most of the front bumper ducting, and adding a low air dam can really help. So my feeling is that under the right conditions, a supercharged ISF e45 tuned can do 195-198mph in 1.5mile.

Didn't realize the aerodynamics of the car would allow for 191 mph. Nice!

Nicely done! Congrats.

So do we actually know what the top speed could be with the supercharger kit if you had enough road/track to max out?

There’s a similar event here in the U.K, thinking about having a go with mine.

Saw a few Audi’s and BMW’s at the last event, be fun to see how it compares, might shock a few people!

I think the odometer reads 200mph for a reason.......

Talking Isf top speed challenge

I think with Jason’s ISF (running 11.1 @ 128mph on e45 tune it would be possible to hit 195 or so.

I know what it takes to run 190.1 mph and I challenge any ISF, Jason or otherwise to beat my 190.1 mph run !!!

Yes I believe we can both hit 200mph, but before we do there's two things YOU need to do.

First hit 171mph
Second hit 190.1mph

Let me know when your done......
