Well,
It is finally done. Almost.
My car is a 1995 RS2, polar silver with 70.000Km. I did a lot of things with chips and filter and exhaust, but I put everything stock again before I did this mod that I will tell.
From the stock RS2, ADU motor I changed:
• Turbo –Water cooled center section, K26#9 or #10, I don’t know, but the “turbo guy†said that is good to 500hp+
• Compressor – TO4E, with (50 trim equivalent size) different design from Garrett, A/R .50
• New hoses from MAF to compressor inlet.
• New, bigger MAF. A Porsche 928 (SQ also) aluminum unit.
• 3’’exhaust, two on one from downpipe (21/2 ‘’on one 3’’). One Huge Flow Master at middle and one (almost pass through) muffler in the back;
• Two auxiliary high pressure Bosch fuel pumps;
• 710N diverter valve;
• No breather hose to the intake. It is collected on an external bottle;
• UNICHIP piggy-back computer with boost control;
• 4bar FPR;
I’m still using stock ECU, stock EM, stock downpipe (only a little machined on the flange to turbine exit), and injectors.
I tried to use the stock MAF, but it blow away its hot wire at 1,5bar @ 7000rpm.
I’m on test phase yet. In Lag department, I’m running 0,2bar @ 3200rpm, 0,5bar @ 3500 rpm, 1bar @ 3700rpm and 1,3bar @ 4000rpm (full boost). 1,2bar @ 7000rpm.
Next week I will leave my car at the UNICHIP (A Porsche Dealer) center and do a new boost map (along with new timing and fuel maps). My intention is run 1,8bar @ 4000rpm (if its possible), 1,7bar@ 5000rpm, 1,6bar @6000rpm and 1,5bar @ 7000rpm. I expect to have ~410-430hp with this. I only run BR’s Podium gasoline (95 octanes IAD – 105RON) with 24% of alcohol).
As soon as I have more pictures and videos I will post’em here.
Regards,
Mark
