Dyno results!!

[j.fro]

I got down to 2700 by:
removing the convertible top, motor, transmissions, and everything else related to the top (got a hard top for driving to and from events)
removing all the carpet
removing all sound deadening
swapping the seats for fiberglass shells (fixed to the floor w/ no adjustments)
radio delete
A/C delete including all pipes and condensors
fiberglass trunklid
removing the automatic spoiler & motor
carbon fiber hood
Borla muffler/cat bypass pipes/headers
LW flywheel
removing all carpet from front & rear trunks
lighter battery

....so now I'm autocrossing in F Prepared

The first time I dynoed the car, it was also lean, and that was before the Softronic flash.
Funny, there's no indication of detonation despite the reading. I've raced the car like this all year. 155,000 miles and she keeps on running.
The readings looked around 18:1below 4K RPM, but then they improved to 14:1 above that.

what maf housing are you using in that setup? if you've got any maf-related fault codes and the car is defaulting to the throttle position to determine airflow, the larger throttle body will mess up your trims.

[j.fro]

I cut the MAF housing from the original airbox. The car isn't throwing any codes, and it has a new MAF and 4 new O2 sensors.

Interesting, given that time and time again it's been said that there is little in the way of "real HP gains to be had by tweaking the exhaust, especially with cheap Chinese eBay headers and bypass pipes. Are you running without cats?

Seems to only be repeated by those who have the equation Chinese = crap drilled into their heads. My China headers were T304 stainless and they gave the 986 a true HP boost and an upper register snarl as awesome as any car. Simply stated the underpulley and headers IMO were the best two 986 mods.

Nice now I get it! The two lids would really contribute to this ........how do you flip your lid once you get to an event? Do you have an extra set of hands

Yeah, searching for someone to help remove the top is now a ritual at AX events...there are a few folks who volunteer knowing I'm gonna ask! Thank goodness everyone's pretty nice.
When the top is off and I'm out working the course, I get noticeably nervous if clouds begin to gather!

And the dyno video...

I had never heard my own car from outside the driver's seat. She's pretty loud!
I didn't hear any detonation during any of the Dyno runs.

We have this guy up here who created an open topped 944 track car....with a big mother of a wing; even the windscreen is gone....it's always raining. He waits for the grid to be released and then pulls out from his motor home awning! Keep a tarp handy or keep moving!! Haha
