wrap around header/and pipe lenght
I just got a krumscheid header for the mvvs 26 gas,due to the tube bendings is impossible to keep the same lengt of the stock header,so the total pipe/header lenght will increase 35 mm. Can these affect the performance ?(I can always cut 35mm of the pipe)

RE: wrap around header/and pipe lenght
Paolo,
Increasing the tuned length of any tuned pipe system will decrease the RPM, at which the maximum boost will take place.
If you are using a relatively large propeller, spinning around 8,000 RPM, there will be little difference, if any, in maximum RPM and it may even take the engine a fraction of a second less, to get there.
If you are maxed out, with an 18x6 prop at 9,000 RPM, however, the top end performance may be reduced a bit, by this slightly greater tuned length.
