Subject: Re: HSR, what can it do by dan0617 on 2009/9/1 1:09:06 I have a HSR on my 383, 230/236 cammed, AFR 195 street ported engine. Has run bottom 12's and I'm sure will hit top 11's on motor. It's set up for the spray (tight converter and short shifts on motor) otherwise I think it would be mid 11's on motor. It has gone a best of 10.66 @ 131 on the spray but will do much better next time out as I fixed quite a few issues and tuned it in better. I love my HSR. However I'm not sure it will be good for a large cubed, high revving engine. Plenum volume is pretty small, especially when cut down to fit in a 'vette. I actually milled 3/8" off of the top of the runners on the base intake so the plenum volume stayed a hair bigger. I love it but I don't think I'd do it on anything over 400 ci, I think other options would be better. Maybe they can be ported out quite a bit and make them more optimal for bigger cubes, that I don't know. Edit: by the looks of the post before mine, I'd say the Stealthram can be ported enough for a large cubed engine! |
