engine is in great condition and I was wondering how much extra power I will get from the following: 1. k and n panel filter in drilled airbox with 2 3inch ram pipes direct from outer wing into airbox 2. stainless steel 4 branch manifold 3. jetex cat bypass pipe 4. scorpion stainless exhaust system 5. always running on super unleaded thanks.
Hi Dave, Not a direct answer to your question, but unless you've already done it, using a KR inlet camshaft is known to be a good upgrade on the 9A engine.
I can't comment on everything but I was running kr cams, air feed into the air box, jetex exhaust with all of the silencers, milltek decat, k and n panel filter and was at 157 bhp on some very honest rollers. I fitted the decat after the other mods and gained 8 bhp alone
