Was that with the same tune? Or?

Yes, that was with the baseline tune.

Compression should be higher, cam is mild.

The convertor was made by Coan for my combo for 99% street use. They said IF it were a race car or a real street strip car that saw a decent amount of track time, they'd set the flash stall to 5k, (500 RPM over max tq)

It is definitely a waste of money!!! I have owned this car for 25 years and have just tried to make it the very best every piece can be.

Curious , how much did Coan want for a special street convertor ??

maybe , but its fun to smoke a hellcat on the hi way ...

I believe there was an on season and off season price. 900-1500 range? I forget. It's been on my shelf for at least 3 seasons now.

Didn’t you have a pic of your engine on the dyno with some fender well type headers?
Were those the 2.125” ones?

Yes they were

My 470 header swap from 2 inch fender well to 2.125 tti step under chassis headers was a 26 HP gain.
Surprisingly the fit perfectly in the car with torsion bars .

My engine builder estimated i'd see 15 to 20 hp going to the 2.125 TTI headers from the 2".

Sounds like he isn't far off.
