Just remember though whatever you do needs to work together as a package. I was sold extractors that were too big and the wrong configuration for i what i wanted. Lost bottom end torque and fuel econnomy. A bigger T.B. and maf will have the same effect. 70mm tb is a bit of overkill and the new stroker with the 82mm is way too big and will gain heaps of bottom end with a smaller tb...XR8chic said:Hi,
I would suggest getting the CAM, Heads, Manifold, Throttle body and MAF before getting a supercharger.
Also might want to consider a reprogrammable performance chip (such as the UniChip).
I recently did a Cam, roller rockers, ported and polished heads (already had extractors exhaust and unichip) and I gained 21rwkw (was 130, now 151)
Still have the stock Manifold, MAF and TB. Also - my extractors are too small for the exhaust ports - I need to get the big bore extractors. (1 5/8 primaries)
Currently running 15.0 on the 1/4 mile (this is with me driving though....) prior to the engine mods, my best was a 15.7
If I get the intake mods and big bore extractors, I should get another 15+ rwkw and hopefully another 0.5 secs (at least) off my 1/4 mile time.
