Thumbs up Mods Dyno Tested!!!!

This is the latest dyno run performed at the same dyno facility (www.harmanmotive.com) where last year we performed the CAI.....exhaust.. and coolant temperature tests. All test were performed on a Dyno Jet front and rear wheel dyno.

The bottom sheets (last June) show baseline stock best run and it took several pulls to get the best due to heat soak on a stock motor, these were done last year when we didnt know any better.

The first graph or dyno sheet is the latest run with GSM ported manifold, GSM phenolic spacers, Mopar/Corsa catback, Kooks headers with high flow cats, modified factory CAI box. Coolant temp was 193. Obviously the combination works........the BIGGEST difference noted by Harman was it did not take 6 pulls to see a good number we did three (3) back to back pulls and all were identical and fourth(4) (not shown) without the air box revealed a 2hp2tq bump at 5500 that immediatedly disappeared. This is a different vehicle than stock !!!

This graph is last June stock VS now with all the mods listed.

Last years dyno runs that speak for themselves

Stock engine last June-Stock air box 180 degrees vs 215 degrees

Re: Mods Dyno Tested!!!!

You hit the nail on the head Steve, looks like a completely different animal. I'm digging the huge difference in area under the curve, and thinking the B&G is going to make a huge difference for both of us.

Wow, I gotta say I'm very impressed! For a long time I was skeptical but you're convincing me with hard data Sarge!

Thanks for being the unofficial "test mule" haha!
