Summer is coming..... Now lamp podless. Makes it look naked.

Fuch'd it back up, now running a 8'' rear AND a 20mm OEM spacer. Hands up who said that Fuchs wouldn't fit! Using a rare 8x16 ET23 version from a 951. Still have 7x16 ET23 up front.

It now goes great too. Dyno’d at 239.5 rwhp, 5800rpm(limited) at 1.05bar.


(who said the stock CIS would not support over 250 crank bhp???)

Very cool, proves what the stock via is capable of!

Is 1.05 bar measured before or after the tb ?

What was the performance with the previous turbo?

Do you use a stock headgasket?

1.05 bar was measured consistently by the dyno using a boost line post IC and pre TB. This line feeds the wastegate + boost controller. It was only 1.05 as that is what I had set on arrival. We didn’t lower or raise during the dyno session. Just also happens to be 0.05 bar more than GTS and 0.05 bar less that GTS Clubsport. However bhp is closer to GTS CS. Happy with that

Not entirely fair against the old 2660 6.10 turbo as other things have changed since and that tune wasn't optimised, but that was 225 crank at 1.0bar. Different dyno, different day.

If I can find a little more fuel, I think 260rwhp / 300 crank is possible. Then I will call it a day chasing hp.

Using Cometic and ARP to clamp the head
