do you have more pictures of the steering servo pump bracket how it is modified to fit the pump in the place with AAN inlet manifold

Needed to take out the pump a bit, so I made some shims. Then I made new holes in the metall plates. I made a new metall plate on the backside to get it further away so that it doesn't make contact with the water pipe. The adjustment piece is lengthened and conected to one of the watrepump screws.Comment

Today we started to map the car. A few pipes blew of at 2 bar but that was sorted out fast. Biggest problem was that the fuel pump was too small, new 044 is on the buy now list, and then the alternator broke down. At the end a safe map was made until a new fuel pump and alternator bought so that the car can be driven.
Here is a pic of TC support.Comment

I think every person should change the OEM fuel pump for a 044 Bosch, even if it's a stock S2. Just to avoid problemsComment

Some updates. Car is now mapped with the new fuel pump and alternator, Don't have any figures but it pulls very nice
Would like to take the car to a dyno but don't have the time at the moment.
Installed a s2 rarb, and the car feels now much more stable.Comment

Some updates: Got some slightly used bilsteins from a forum member together with track density top mounts, together with powerflex bushings all around. Havent tried the car yet because I found a big crack in the china EM and just being welded.
I also got the revcounter working (ECU pin40 straight to black/red behind the dash) but there is still something strange because it starts to jump up and down after 5000rpm.Comment

Summer is at its end and now I finally got the car to a dyno. I was hoping for 400hp from the engine but I got 280,4 kW from the wheels so I'm satisfied
Boost pressure at the dyno was only 1.9bar, on the road it is 2.3bar on 4:th gear. This is propably because the rollers are too light, at least according to the teacher at the school. So the power could be a little higher but who cares.
Only thing I that bothers me is the dip when the boost comes on. For some reason it goes rich 10.5 (maybe FPR?). You can feel this also, small hesitation and then all the power comes on.
I regret that I didn't do a pull on 5:th gear. This hesitation can't be felt on 5:th gear.Comment

What turbo are you running? seems to boost late compared to the KW/HP numbers you posted.Comment

Nice car. Great project. I see you said 3B but I see an ABY or AAN head, ABY cam cover and AAN intake manifold. Is that correct? Is the AAN head an early one with the Hall Sender in "tuna can" dizzy attached to the rear of the head? (I don't see the G40 wiring at the front).

Thanks for the specs. I still can't see the G40 Hall Sender wiring at the front (but it must be there then). Cam cover looks to by ABY or ADU because of the "L" shaped tube for the PCV system at the front exhaust side (and the slope of the cover on the front intake side).
I *think*
