Intake manifold modifications

This was a cheap F1 racing clutch from eBay. The purpose was to hold until I went turbo, so I didn't figure it mattered. I think it would have been ok, but my master cylinder leaks off over time and sometimes the pedal will stick partway down with the clutch only about half engaged. I think this happened to one of my friends when he was driving the car, the pedal effort was significantly decreased when I drove it next (I think that the pressure plate got hot enough to partially anneal the engagement springs).

I intend to remove the engine soon (I can't drive the car anyway) and see what I can see.

I got the F1 racing clutch mostly for the rev rating (9500 rpm) which I figured was all my engine could safely do. Now that I have trailing ignition for both rotors I expect to need that rev rating.

If I had intended the car to end up as NA, I would have purchased a better clutch. I have a stage 3+ SPEC clutch (505 lb-ft rated) and a billet steel 10 lb flywheel for the turbo build.

If I ever get the time and ambition, I will install the turbo drivetrain in the car.
