Horsepower and hoosiers made my car way easier to drive. You can get avons true slicks WAY easier than we can since you're in Europe, run some of those bad boys.

It’s a shame that they are prohibited in my Club –class (i.e. modified street cars). Tire rule is TW140 and in Europe we don’t have much R15 225/45 street tires. RS-3 and BFG Rivals apparently don’t have some European road approval thing. I guess next year I have to ship tires from US

Short but cool video from last Saturday’s race


Unfortunately Competition Clutches sent me wrong pressure plate for my twin disc. So I had to drive with the old worn clutch and lower the boost to ~10psi which feels like slow N/A.

Brought back good memories from Ahvenisto! And nice driving car works well too since you had to lift to the tower corner even with cone chicane!

SO AWESOME. I lol'd @ 10psi feeling like slow NA, but I'm sure that is true with the power you are used to. Still looked awesome and quick. Love the data overlay on the video too. Bueno.

Competition Clutch twin disc is in




It took 8 hours to change. I could have gone faster with beer



And hereís why it take so long me to get that new clutch. Competition clutch had to make new pressure ring with chamfered drive flanges. With the original pressure ring, the clutch will not disengage.

Did a quick tracktest with the new clutch. Next Tuesday I’m going to the same track again and do a longer test drive. It’s my local track. Nicely renewed as you can see from the asphalt

@ 18-19psi

There were few corners when I had trouble getting in third gear. On the way home I notice that fifth gear won’t go in every time. This morning I find out that when in stationary fifth and reverse won’t work anymore! ****.. It has to be something with the gear selector rod etc...

It has changed quite a bit, new extension seems to be good improvement from original set up.
It was hometrack fo me as well, about 30 km where I was born.

Here's longer testing/practice session from last Tuesday

first run:
- Boost settings are wrong. Boost drop to 15psi near redline
- AFRís are also off. 12.5:1 towards the redline.
- After six laps my TSE 11.75Ē brakes started to fade. Must be due to street brake pads (Hawk HP+).
- Water temp went to +111c. A new record



second run:
- Boost map fixed. 18-19psi whole time
- AFRís fixed as well.
- Occasional boost-cut at 22psi. I had to fine tune my PID settings more
- Injectors are now officially max out. Fuel pressure is 90psi and injector DC is 94% near the redline

No need for new injectors, just raise (somehow) voltage to 16V

Can you dyno it? And I wonder if your 3.5" downpipe makes any difference. I thought about going bigger but everyone says that 3" is more than sufficient.

He's still running old EV6 style injectors, so the ID1300s will be an improvement in more than 1 way.

I haven't considered doing a 3.5" downpipe, but if there's room then why not. My plan is to build something like the Wittyworks setup you have, what do you think, is there room for it?

I'd like to see good pics of these 3.5 dp's clearing everything because the last couple that we fabricated it was super tight in there, and that was with just a 3"
