Hi,
I am wondering about the need, or otherwise, for exhaust backpressure im a 4.2 QP.
In my younger days of drag racing, I ran a 275bhp drag bike which sported an open exhaust, which, if run for more than a short time, would overheat and damage the exhaust/inlet valves in quick time. The reason, it seems, was a lack of backpressure due to the totally open exhaust.
Zip forward to the present day and I am toying with the idea of releasing the glorious noise of the V8 (in short, sharp sessions), through the use of electric exhaust cut-outs. While it is a fairly straight-forward job, the concern I have is the possibility ofdamage the lack of backpressure (while the cut-outs are open) may cause to the motor.
Any thoughts on this issue out there?
Slan,
Pat.
