Do you have a workshop? would the 1147c be a stage 1 or stage 2 or stage 3 cam as opposed to 818 cam? Also what are the prices or 1147 and 818 cam? cheers They're all pretty much the same price the 1147 is massive compared to the 818 and bigger then 1522 At 232deg@50 .506 valve lift and 110 lobe separation Rpm 3200-7500 or there abouts

I called camtech and talked to them about what cam would suit my setup: N/A bottom end with cometic 75thou HG lowering it to around 8.3 compression turbonetics t66 .81 rear 353cc injectors z32afm FMIC 3" exhaust dumped out the side 50mm wastegate nistune I wanted a cam for circuit racing with more low end torque that would be fine with pump 98 and avgas, up to 6400rpm at 15-20psi. The cam that they recommended was the CT503 524A-115 (drop in cam) Look up the cam specs on their website www.camtechcams.com.au (http://www.camtechcams.com.au) Camshaft $385.00 Valve springs $158.40 Haven't gotten it dyno'd, I just street tune it myself, but my guess is around 250-270rwkw, maybe a little more or less, who knows? But it hauls arse all the way to the redline, so I strongly recommend it. Hope you find a good one mate
