Subject: Re: HSR, what can it do by dan0617 on 2009/9/2 13:48:18 The uneven cylinder distributon problem exists with all front loading intakes, including the stock TPI. Shows up more and more the more you flow and the higher you rev and the more power you make. On my Stealthram, on the top of the runners where they meet the plenum, I ported and smoothed out the fronts quite a bit, the mid ones a little, and the rear ones none. My problem was opposite what you found. At WOT while spraying, my rear plugs were leaner than the fronts. Actually when I was lean and the plug range was too hot, the front spark plugs blistered a little, the mid ones melted the ground straps, and the rear ones were completely melted along with the exhaust valve. I have found during very light throttle driving the fronts run a hair leaner but not too bad. Now with the porting the way I did the WOT on the spray looks pretty even. |
