Re: Exhaust connection fitting
Ill bet his flanges are not mismatched like that.I think he was saying in this case the port should not be enlarged to match the flanges. But I think correctly made flanges should match the port without having to modify it.T.RexRacing wrote:You guys do realize who Kenny is right?

Re: Exhaust connection fitting
Thank you of road!
@jackb i think every flange for a spring fit has a straigth piece of tube.
No 8deg angles here. It seems to me that this is straight piece is less obstructif than disruptions.
I will post pictures here when its done.

Re: Exhaust connection fitting
I get best power with the pipe header at 37mm ID port is 33-33.5mm usually it is also NOT usually central to the casket face so making the diameter match is very tricky unless you have each individual mounting flange CNC cut to fit. A step of approx 2mm all around from the pipe ID to the port exit ID isnt ideal but as its a single port it doesnt seem to make to much difference. Hence I get best power at the previously stated diameter.

Not so my friend I make tapered flanges where the pipes start with a taper too. This depends on what the engine reponds best too.Marrcel wrote:Thank you of road!

Re: Exhaust connection fitting
As Kenny states, tapered is best. Smooth tapered is most desirable.

Re: Exhaust connection fitting
This is the result. Smoothed out. Kept the 33mm diameter.
