Stillen SC kit recommended upgrades?

JWillis72 · 11-25-2014, 02:59 PM

There are a lot of us that would love to know what exactly caused the problems! I would love more power but I don't want to be on that list!

JWillis is right if you stay on the 8PSI pulley you should be, SHOULD be fine, I made 412 WHP and 320 WTRQ on their "stock" kit custom tune of course. I then went for 500WHP and the motor quit at 457 WHP and 330 WHTQ @ 12 PSI. I was seeing 9 PSI on the stock set up, An I only did the impeller upgrade but had all the fueling upgraded and UPREV mafs. You'll need only the heat exchanger if you plan on staying at 8-9 PSI.

If I could do it all over again I would have stayed t 412 WHP and be still driving it and not looking to buy another one

Same boat as you, my kit was just fine at 430WHP and then when i upgraded the kit, motor gave out at 510WHP (ran meth as well), leave the kit alone and enjoy the car, the extra 50-60hp not worth it for the amount of the long term headache you will go through TRUST ME!

Thank you both! I'm sorry for your troubles but you guys posting your trouble kept me away from getting hung up on the numbers!

I appreciate the info too. My SC kit gets installed next week.

JWillis72 · 11-26-2014, 06:23 AM

I see you live in AZ, start thinking about cooling! Good luck with the car!

brutusvk · 11-26-2014, 05:50 PM

I already have the 34 row oil cooler and the transmission cooler is getting installed with the SC. I planned ahead.

When the temp is under 70 right now it has trouble reaching proper temp. I am sure FI will change that.

JWillis72 · 11-26-2014, 06:33 PM

That should work as long as you don't drive in a lot of stop and go traffic and don't plan to track it.

brucelidat · 11-26-2014, 08:08 PM

Are you saying a 34 row oil cooler won't be enough for stop and go traffic or tracking?

brutusvk · 11-26-2014, 08:23 PM

It's been more than enough in 117 degree weather and stop and go. But maybe I am just lucky.

brucelidat · 11-26-2014, 08:35 PM

I currently only have a 25 row cooler, wonder if that would be enough

It won't if you track the car.

With a 34 row in the summer on track n/a the car can easily hit oil temps of 240-260 deg at places like Sebring or Roebling.

Hey man its an awesome kit mine has 40k miles on it and I still make 440whp. 315trq. I have all the same upgrades. These guys are right you gotta go custom tune! I had uprev tune mine and it runs like a champ. Good luck man!

brutusvk · 12-04-2014, 07:17 PM

Mine is at the shop right now. I pick it up Monday after we tune it. (I like watching the dyno runs lol) I upgraded the bypass valve too. Of course getting it custom tuned. I am hoping for a safe 420 to 440 hp.
