This intake produced 254 whp with E85 and VEMS ECU, completely stock 968 engine. With Motronic and gas it made 209 whp, with VEMS ECU 221 whp, with E85 228 whp and finally with intake 254 whp. Runs were made on Dynapack hub dyno.
It is milled in 5axis CNC (including protruding trumpets), then sheetmetal is welded to finalise the plenum. Engine resides in '82 924.
Never tested the intake with Motronic, gains would not be that big because at least two reasons: Motronic cannot run E85 properly and timing would also be off.

would be interested in seeing the results of the intake + gasoline...since the 4v head doesnt need much timing the benefits of e85 are probably limited in NA form with only 11:1 cr, no?
