This ^^^^^

I am also very interested in this kit but worry greatly about reliability. I read a few posts on this forum claiming that the Stillen maps blow up cars.

I'm running the 8 lb stock kit with a frozen boost cooler ( lots of users here use them with the Stillen sc) to keep the SC cool. I can't say my car could do 25 hours but it does track weekends pushing it to 7000+ rpm with no problem even in the Florida heat.

Great thread. I stayed n/a (with z1 400 hp kit) because I've watch so many supercharged rides overheat and fall off the pace tracking. (Mostly roushe mustangs, monster Miatas and corvettes.)

I track in Colorado where it's hot (90+) and air is thin (less cooling). Supercharged track cars seem to really struggle up here at the track.

Subd to see what y'all have to say on this one.

Great to hear! And those track days are the usual four, 20-30min sessions broken up as two in the morning and two in the afternoon? Do you have to do anything special to cool the car down between sessions aside from popping the hood and letting it idle in neutral with the wheels chocked for a few minutes? I noticed in your avatar pic that you have a vented hood. That might be the key to everything.

Any other owners want to chime in with their experiences tracking a Stillen Supercharged VQ motor?

The vented hood was one of my first attempts at cooling and it did help a bunch. The more air you can get out of the engine bay the more air you can get through the coolers and the less heat you trap. Most of the track days around here are 4-25 min sessions but some are 5-25 and a 45 min open track at the end. My car is a 7 AT and all I do is stick it in park and pop the hood between sessions. The key was getting all the coolers where they all had good air flow and not near each other .

Nice! It's very informative to see what a successful setup looks like. Thanks for posting it up!

JWillis72 · 05-15-2015, 03:46 PM

we also vented the wheel liners to get the heat out.

Yup, figured as much!

brucelidat · 05-20-2015, 03:31 PM

so those of you with this kit, does the car feel noticeably faster across the entire rev range or really only when you get on it and get up into the 5k+ range?

EliteXpress · 05-20-2015, 04:22 PM

My Kit has the 9lb Pully, Boost for me on the But Dyno is felt around 3,000 RPM

Mine the stock kit and mine is around 3000 also when it starts pulling. Very stock feeling the first 20-25% of the gas pedal then it's a different car.

Did you do anything to the tranny , thinking of having Level 10 complete bullet proof upgrade, or do I even need it

brucelidat · 05-21-2015, 12:56 AM

Ir doesn't seem like you need it if you are running the stock kit.
