680OST Regular Registered: August 2004	Re: 1ggte plenum Fri, 28 January 2005 23:48 stradlater, I can understand wen some people get scepticle about comparing thier own engine to ther figures, but, there are many factors that make huge differences to power. I forgot to mention in my first engine it had NA cams in it, which is no big deal. The head is relatively easy to remove if your mechanically inclined, my head is hand ported and my new intake manifold is a TT one power ported. The engine when first built had a supercharged intake manifold, cut off just where the plenum usually joins the runners, and had a 15mm flat plate welded to the runners. it was 75mm wide and I think about 450-500mm long, and this was thick enough to hand port bell mouths into the top of each runner. It then had a curved aluminium top, not unlike half of a 4" tube welded on, with an XF throttle on the front. This, with cams, and possibly cooler and exhaust manifold could realistically add 100hp to your engine, i don't know, I had as big a cooler as would fit from Micks metalcraft, at 600x280x90mm, and my exhaust is basically a straight pipe all the way through, under the diff, with 1 straight through muffler and not cat in sight. Then there is the 4 pounds extra boost, and the possibility that I was running 5-10 degrees more timing, I think I had 21 degrees of ignition timing at 29psi and 12.8:1 A/F. Compare these to some of the similarities of your engine and see whats different. 6BOOST [Report message to a moderator]
