Out of curiosity, do you think 15% is high or low?
No idea, that's what I'd like to know. Each car (and dyno) is different so...

10 to 12% with warm differential, tires at 36 psi, 75-90 amsoil differential oil, run trans in gear that is 1:1, 6th in SMG, 5-30 amsoil syncromesh trans fluid.

There is a reason this car has 200 mph top speed with only 507 hp

Soon.

This engine wasn't running when it came in, so no way to do a test.

I did get a pre-header dyno from a local guy, but we weren't able to schedule the post-header dyno in time for him to pick up and he honestly didn't care about the numbers, so it was hard to convince him.

I have another here from MN that is finally going under the knife. It will be 100% before and after. The goal on that one is:

- as arrive dyno
- headers installed dyno
- headers and eventuri
- headers, eventuri, tune

The dyno I use is a Land and Sea hub dyno and to truly calibrate the mss65 for this one, we are looking at about 20 hours on the dyno.

- disable MAFs and run as alphaN
- reenable EGT probes (they were disused and abandoned in place on early cars)
- disable closed loop fueling (lambda sensor fuel trim)
- map every single cell of the VE tables to the correct fuel values
- map lambda targets for optimal power above cruise, optimal economy in cruise
- map all ignition advance cells for MBT
- re-enable closed loop fueling

Results to follow.

The last video is filmed using a GoPro with Behringer ECM-8000 Studio reference Mic on the trunk with a wind guard. It's about 18"from the exhaust tips. It was obnoxious on a straight piped car. If it sounded that loud inside, I wouldn't have managed highway runs.

One set in stock, not spoken for. Arrived this morning, customer backed out at the last minute. Test fitting today to make sure everything is good and will be ready to ship by Monday.

Too many posts on the headers for me to catch up on.

Is there a difference between the RHD and LHD headers?
