The 2 Ptuning kits on the list: one shows WAAAAY more torque than normal. I. Any find any posts from the owner and I’m wondering what the deal is with the high torque number. Based on the f20 Ptuning kits number my current clutch is good. The f22’s torque is beyond my current clutches limit.

 

Which clutch? How much boost do you plan on running?

 

475-560. It’s the grossly different torque numbers between the 2 Ptuning setups on the power chart that have me scratching my head.

The 2 on the power chart made 560-580hp, but one made 470 jt lbs and the other made 379 ft lbs.
My current clutch will hold if the torque if it’s 380, but not if it’s 470.

 

it wont make 470tq if you're in the 570hp range especially on our motors.

 

A forum member made 580 hp and 470 ft. Lbs on the chart. That’s what has me scratching my head.

 

That was probably meant to be 370 lbft.

 

Must be. It seemed like waaay too much torque.

 

I been running my ptuning setup for 7+ years now. Gtx3076r e85 22psi of boost stock block f20c 588whp419 tq
425whp 293tq is the tune on 91octane but I always drive on e85.

dyno is a dynopac and its right at sea level. Churches dyno is know to real a little high.

 

Damn! Makes me want to run e85. I’m betting it spools pretty fast?

For reasons I can’t figure out we don’t have ANY e85 in Seattle. We recycle, we have all these climate chargers per gallon on our pump gas, we have the Nation's most radically green Governor… and NO e85 in Seattle. The nearest source is one hour North and the other is a bit over an hour South.

Quick question;

Any driveline upgrades? Has your transmission done OK?

 

stock original transmission with 140,000 miles. Clutch is a science of speed carbon twin disc. I’m have blown 3 diffs so I’m in my 4th diff. First one was stock. Second blown was was a comp tech reinforced diff. 3rd one was a puddy mod stage 3 and I’m currently on another puddy mod stage 3 with 3.9 final drive.

e85 for turbo cars make a huge difference. 10 years ago here in Los Angeles there was like one station with e85 but it’s grown like crazy in the past 5 years. Now e85 is pretty common. Probably 50+ station with e85 in the area now.
