Finally got my performance parts installed and a dyno tune today. Mods are Western Motorsports High Velocity Intake, port and polished throttle body, Steeda charge motion delete plates and under drive pulleys, MAC long tube (mid-length) headers, off-road MAC ProChamber, Bassani Race AB's, and 4.10 gears tuned by Performance Evolution on 93.

Base dyno on 4.10 gears only was 270 RWHP and 293 RWTQ
New dyno with above mods was 330 RWHP and 336 RWTQ

By the numbers from 2,530 to 6,020 RPM
Peak gains by RPM (not overall peak) were 65.6 RWHP and 57 RWTQ
Average gains were 37.3 RWHP and 43.8 RWTQ
Minimum gains 13.6 RWHP and 26 RWTQ

Was hoping for 325 RWHP and 330 RWTQ. I am very happy with the results.

Very nice...it looks like it kept building power at 6k. Is the limiter set at 6k?

Damn good numbers! No cams either?

That's superb, Jcon! Congrats!

JCON

Thanks! He said it started to drop off after 6k so he stopped there. May run it at a dyno day from 2-6.4k just to see. No cams or heads.

For the cost, I'll probably just get an aluminum drive shaft and rear LCA relocation brackets and call it a day for a while.

really good, what do you think added the most power? Id guess longtubes and offroad prochamber mixed with the 93 tune probably was the majority of gains, everything else must have helped too though. Whats your theory?

JCON

Not quite sure. With my Mac long tubes and off road ProChamber I went from a max of 270 RWHP and ~293 RWTQ to 283 RWHP and 296 RWTQ.

Then this weekend I added my intake, charge motion deletes, under drive pulleys, and a 93 octane dyno tune and went to 330 RWHP and 336 RWTQ. So I would say the exhaust alone was not the majority but definitely complimented the other mods. Later this week I hope to do a little more in depth write up and comparison.

Good numbers for sure but it is a Dyno run. Just as long as everything looked good then that's all that matters

JCON

yeah just a dyno. All the numbers looked great. I would like to get out to a 1/4 this summer and see what I can do.

That is some good power there!
