plus I run E85

I did one virtual dyno 5th gear pull today with 19psi and it was around 380whp.

The two ways to get more holding power out of a clutch are with a grippier friction material or more clamping force. There is a clutch shop here in town that re-springs pressure plates for everything from heavy trucks to race cars. There has to be someone over there doing similar things. Just an idea.

Well, clutch has been holding fine on the track. It's just fifth and sixth gear that slips. And only on highway driving when it gets hot.





Got second place in last race. Excellent position considers that these were my brakes:



TSE BBK package should be here in Finland at Jul/11

And video how to drive without brakes:

I really like how the car drives. Those cheap Federal RS-R tires are awesome for their price and with the new wheel alignment car easy to throw around. With roughly 340whp it’s not slow either. When I get my 11.75” TSE brakes I think it’s going to be very well balanced weekend race car.

Haha nice driving without the brakes! Did you have smoke coming off the rotors when you finished?

A lot worse actually 8:40 mark on that video I boiled my brake fluids and hit my brake pedal to the floor. Luckily it was on long straight so I manage to turn quick and roll end of that dragstrip.

Haven’t done much lately. Car works suspiciously well so there’s nothing to do... Just waiting to get money for the twin disc clutch


Cleaned my injectors thought. I guess they were pretty clogged as my WOT pull AFR’s went from 11.8:1 to 10.8:1

The exhaust side engine bay one sounds good, can you get the mic near the rear muffler?

Car looks seriously quick!

Excellent video! Though I was let down when I realized you were not driving to the store to pick up more cameras (nor going to visit Mikko or Jari-Matti.)

I spare my GoPro money to the twin disc clutch so I can run 23psi and left Mikko & Jari-Matti behind

First of all, LOVE THE VIDEOS!! Keep making more and more

Next time you shoot a vid, do me a favor and:
-attach the camera to your steering column so that the speedo and tach are both clearly visible.
-do 1-4th or whatever gears you're comfortable going through.

No need to shift fast or do anything crazy. I'm just fascinated with comparing peoples speedometer sweep and trying to get an idea of what kind of power relates to what kind of needle movement.

lol hope that makes sense

Of course.

Or simulated on the computer.

Or done with the car in the air just spinning its wheels.

Or......

OR at least in mass, wait 7 days before posting it because that's the statute of limitations on moving violations.

After cleaning injectors I had to make fuel maps pretty much from the beginning. I also lower the fuel pressure from 85psi to 70psi

I hope this make your needle move Though it’s still only 15psi


btw. I record new virtual dyno pull: (And again, I had calibrated my virtual dyno profile against local Dyno Dynamics )


Dat torque curve Don’t mind that lean spike. My wideband needs a cleaning and free air calibration
