The car is a 1988 930 Turbo w/ 81,000 miles. The only mods are-

K-27-7200 turbo
GHL Dual 3" Exhaust
Tial Wastegate

I beleive the HP to be around 330hp at the flywheel.

Any thoughts on the Horspower, torque or AFR's?

Its looks to me that I am running very rich, especially in the mid-range. Also, my max torque was actually higher than max horsepower. I always thought that on a turbo the HP would always be greater than the TQ.

Blaine, my '92 in stock (B&B Muffler) form did 283.3 HP and 330.7 Torque on the same dyno.

 

It is a tad rich, but not much. Your numbers are apx 330 and your HP will normally be less compared to TQ on turbos. It is a nice curve. I would expect more, but you were not hitting 1 bar. That is probably costing you 10 to the wheels.

 

Good numbers Blaine....has your engine ever been rebuilt or is that factory with 81K?

Very good graph and I would be very happy with that.

Stephen,

I do not have a 1 bar spring, I have the .8bar. I thought I would wait on the 1 bar spring until after I bought your new intercooler. Remember..........., the NEW intercooler you are coming out with?

Also, my CO was set to 4%, which is probably to rich for this setup. Should I set it at 3%?


Slownrusty,

Engine is stock aside, from the K27-7200, Tial wastgate and the GHL muffler. It runs real good right now, proof that you should "drive it like you stole it".

When I bought the car the leakdown was 10% across the board. Given that I bought the car from the original owner, a retired dentist, I ran some Techron in the fuel tank and took it for some spirited drives. Now the leakdown is 6% across.

Thanks for the comments.
