Dyno - SRM K24's

I posted a thread back in Sep 2016 with the following chart (stock K16's, 3" catless, UMW tune, 91 octane, RWD).







Since then (2018) installed SRM K24's, Injectors, GT2RS I/C's, Marski mafless tune, filters on turbo's. The mafless tune has run flawless for a year.

Finally got around to getting it Dyno'd this week.

Same: shop, dyno, operator, 91 pump gas & RWD. Here are the results :



More on the red run vs. green run later.


I asked the operator for a overlay from my baseline . . . still waiting . . . quicker to draw it on the new graph.




Green run was with Super 10 mufflers on the UW 3" catless.

I removed the mufflers for the red run and slipped on the original end pipes (resulting in the standard UW 3" SS catless).

I was surprised the Super 10's back pressure helped a little up to 4250 rpm and only cost 10-15 hp above 5250 rpm.

The super 10's quiet down the car noticeably, huge difference at cold start-up.

Ignore the electric cut-outs, the cold start-up is very reasonable, so I removed them.

Those are solid numbers for 91 octane.
