This is my new 2,8L MFI LS.
We had a second run on the MAHA this week and Valentin Schneider of TS Motorsport did his magic again on the rolling road. We finally came out at around 282 HP @7,0k RPM and 220 ft-lbs @4,1k RPM.
It features a lightened & knife-edged 70,4 crank, streamlined and shuffle-pinned 7R cases, RSR flywheel with Sachs Sport alloy pp, 92mm JE pistons 10,5:1 with custom coated Nikasil cylinders (at Mahle factory), Carrillos, 964 oil pump, DC60 cams w/ 105 lobe center, 41/ 41mm ports, bored throttle bodies with 43mm butterflies, bored mag stacks with 43mm bottom/ 48mm top with 48mm funnels, 010 MFI Bosch pump reworked by Koller & Schwemmer with custom space cam, custom made twin-plug distributor with reworked 3-pin Bosch CDIs (mounted on Barrie's very nice twin CDI board!) etc.
The space cam Koller configured is very near 2.8RSR specs and it is nice to see that it does not lean out at the top end as we initially feared. What impresses us again and again is how well the DC60s perform down-low. I have a stock 915/03 mag RS gearbox in the car and the ratios fit perfect.
Best,
Christian
