Sorry to hijack the thread . Nick did you get those figures using the Flat Four Headers and if so did Andy think they performed as well as the proper GT Spec headers ?
I have been seriously considering getting some, I had proper Gt Spec headers on my last car but they were so much more expensive.

That's me. Nick and I run a virtually identical engine spec, except that he has a decat, whereas I run a sports cat. Given that I'm probably down about 10bhp due to the cat losses and the 321H is reputed to make around an extra 20bhp more than the 20G, the expected difference in performance between our 2 cars should be just about nil, taking into account engine to engine variations. My clutch problem appears to be temporary, so I will be heading up to see AndyF for a delta-dash run soon. I will ask Andy if he can overlay the plots from the Nick's 20G and my 321H, although I would expect them to be quite similar
