On Friday night, I had 2 runs at Willowbank Raceway using Version 1 E30 tune and launching in 1st gear with the 8HP75 transmission. Results were a [email protected] followed by a [email protected]. The 60' times were 1.637s and 1.581s. Log for 10.6s run below.
10s runs on E30 and 20psi boost

Yes I will have to reinstall my PI to go back to 100% E85. That was only version 1 of the E30 tune. Ken (Wedge) has already sent me version 2 to try. More ethanol and boost should get the car into the low 10s hopefully.

What set up ?
Any weight reduction ?
Great times !
What gear and rpm at the trap ?
Bolt-ons which include RB GF 19T turbos, AR catless downpipes, dual 3" exhaust, Wedge tune, 8HP75, M3 diff and axles with 3.45 ratio . No weight reduction. 6,000rpm in 6th gear through the traps.
I'm on the waiting list for a set of RB GF High Flows. The more research I do, outside of outstanding quality, is posts like these. Even at just 20PSI these twins put down some serious performance. Another member got 516whp at just 18-19psi on 93oct. Almost 700whp on E85@ 27psi. These things are incredible without even breaking a sweat.
8HP75 was installed by Simply Tuning and Andrew (Zero to 60 Youtube) using the TurboLamik TCU

Nice! The RB Two's aren't bad either. I'm running 10.90's at 129mph with nothing but bolt-ons, RB Twos, and a custom E40 tune at 25psi...launching in 2nd gear. Well...that's what the car ran last year.
Very good result . What 60' times are you getting launching in 2nd gear. With the 8spd, my 60' times improved 2 tenths by launching in 1st compared with 2nd.
I was turning 1.80-1.85 60ft times. I had to launch from second gear because first gear would just blow the tires off. I was running Firestone Firehawk indy 500's.......not a drag radial, so I had to take it really easy on the launches. Sometimes it would even spin up the tires at the top of second gear when the boost would ramp up. I was shocked at how quick it was for basically a bolt-on car with RB 2's, and the stock DI setup. It's pretty much maxing out the HPFP......but it's also pretty much out of the efficiency range of the RB 2's....so it's a pretty well matched setup.
I have some stickier tires now.....and was planning on heading to the track again soon, but now I have an issue with a piston/ring in cylinder 4, so the motor has to come out. No trips to the track for me this summer.
Yes I used the trans brake. The trans brake was set at 3,500rpm and boost was about 19psi at launch. This resulted in good 60' times but the launch was savage and has resulted in major damage to the M3 diff. Crown and pinion gears and bearings have to be replaced. You would require a stronger rear end if the trans brake is used. I will try a stalled TC next time as it less savage on the drive train.
