Did you have the oil and tranny cooler during that first year with the stock cooling and street driving?

All these little things make me a little hesitant to do it. I want the car to be solid and reliable without any issues that I can confidently take for a long road trip without worries. It's too bad the GTM sc kit isn't CARB and that GTM is a shady business I can't support (if they are even still around)

I did oil and trans coolers before the SC. Road trips are no problem and for street driving I don't think the frozen boost cooler is needed. I tracked mine hard with the stock cooler and never had trouble.

Okay, so the stock kit is good enough for normal spirited driving/canyons carving and possibly the occasional beginner track duty. What are you 7AT guys getting with the stock kit, about 400whp 300wtrq?

418/312 but I'm at sea level.

SAE or STD? I'm only like 400 ft above sea level so shouldn't be much of a diff, maybe a few hp.

Attachment 102307

It was STD and I gave slightly wrong numbers, it was 418/311.

I ran the kit stock for over a year and the only problem on the street was high oil/water temps in the heat of summer and even then the only times it got out of control was when the car was running and sitting in traffic. The track is a different story, it has taken 1 1/2 years to get all of the cooling under control. It only took adding a vented hood, oil cooler, 7AT cooler, frozen boost cooler, CSF triple pass radiator(not really for the 7AT but I used it anyway), Stillen front bumper, deleting the windshield washer fluid tank, adding fans, venting the wheel well liners and lots of moving parts around.

Wow, did realize you went quite that far with the cooling. Understandable. We have done similar mods on NA track 370's out here.

I'll probably spring for the FI crash bar. But it's a general consensus that the kit is pretty safe with the 9lb pulley if that's the only upgrade you do? Or should I really stick to the 8lb one that comes with it?

On 91 octane you'll have here in Cali I would stay away from the 9 lb pulley. For the 93 octane guys it is still risky but at least they have the octane to work with. We don't have that here in Cali (unless you're planning on running Water/Meth or Higher Octane Fuel all the time).

Shoot me a PM sometime. We can chat about the kit more.

The standard kit is very reliable and I know how to set up the cars to have sufficient cooling for whatever you will be doing (Heavy Track Duty is tough but I have guys doing pretty much everything these days). We can also install the kit and do a customer CARB legal tune for you here at STILLEN.

The best numbers we have seen out of a 7AT locally is 436 whp on a stock kit with STILLEN Exhaust. Typical is in the 410 whp range though (Numbers also depend on how hot it is that day). Torque is usually in the 285-300 lb-ft range.

It took a lot but it's working great!

That fan setup is sweet for your oil cooler!

Thanks, it works great with the Stillen bumper.

that's awesome man, great idea!

kudos.

Everyone I talk to says it doesn't make sense for the SC to make less power with headers/test pipes unless the SC unit can't push enough air which they say shouldn't be the case with the vortech unit in the kit. It has been suggested to me that Stillen's stance might be based off of their CARB approval and not being able to endorse race applications because of it.

Are there any independent customer dynos to confirm this claim of lower power with headers/TPs?

Mark has said he didn't save any dyno to show them compared but I can tell you he is the guy I call for everything about the kit. He has even taken my calls from the pits at Sebring on Saturdays. I have about everything they sell on my car and he told me it wouldn't help, I don't get it either but there has to be a reason he didn't sell them to me. If you don't even have the kit yet what is the rush to molest it before you have even driven the car with it? Don't take that meanly, I'm just curious.
