Engine upgrade- did you do one

Doesn't "need" any mods, & cut all emissions in half compared to 75K stock test.

Here's a chassis dyno test with NHP sportcat manifolds & midpipes:





Waiting for the summer blend 91 octane gas to retest with the added Cayman airbox,75mm T/B & 997 plenum. expecting about 20hp.

Byprodriver,

Nice jump in power over a stock 3.2. Looks like about the same power level as a stock 2002 3.6 without the hassles of a transplant plus you addressed known M96 weaknesses. Is that a fair assessment?

This configuration gives more low RPM torque which really quickens acceleration in the real world & makes it so much easier to drive. I usually drive mine like a 3-speed now. 1st to 3rd to 5th. While the engine is apart you can send the IMS to LN for their triple row IMSB upgrade too.
Also balancing the engine reciprocating parts really makes it much smoother.
