Low boost was about 22psi.
interesting point, same tune that was on rollers made 319 and on the hub 350, so just 1 psi of boost and more timing it made 32 rwkW more. The waste gate is fully closed now at 31 psi so out of turbo which is what I wanted to achieve

I've been running 245/40 x 18 Mickey Thompson ET streets, these were 2nd hand and pretty old and the side walls don't have a lot of give.
A local speed shop had a special on some M&H 245/55 x 15 drag radials. There was no 15 inch Porsche factory wheel that would work because my wheel bolt face is pushed out a long way by my 944 trailing arms so I had a pair of 15x6 Cookie cutters widened on the inside to 8.25 inch to take these tyres. They worked out at ET 65. My local tyre guy did a finger balance rather than a cone balance for me

Thanks, it wasn't cheap but neither was buying 3 piece rims so that I could get the correct offset.
I did feel a little guilty having genuine Porsche wheels modified, I'm over it now

Here in the Netherlands a lot of genuine Porsche rims are massacred for the auto cross (widened and narrowed). And after some beating they will end up in the trashcan.....
So don't feel guilty

Hi
Finally got a dry Wednesday night so I took my bug out to the drags. Getting used to launching and shifting gears again, I need some improvement. I was getting some wheel hop which I'm sure caused me to break a drive shaft. I need to tie the motor and trans down a bit better Its a custom drive shaft, modified 944 with a 930 CV flange welded on. The guy who made them cant do anything for 5 weeks so I'm trying to organise getting one done so that I can run at the VW Nationals Supersprint. If anybody knows of someone that could help with welding and machining let me know. Best ET was 11.803 and best MPH 124.29

Hi
I had some new billet 944 stub axles made in in EN26. Im fitting some Subaru Group N engine mounts when they turn up from Japan and Ive fitted Superpro urethane bushes to the front engine mount cross member. Hopefully this might help my wheel hop issue

Last year I fitted some twin Spal fans to my 944 radiator. I had to cut the housing a bit to fit them.
I've just fitted dual thermo fan switch in radiator as used in Alfas. It has the same M22 thread that's in my radiator. The only one I could find with a suitable temperature range was made by Tridion with Operating Temp: 92°C - 87°C & 97°C - 92°C
