Subject: How much HP gain with ported plenum and runners??? by WW7 on 2009/8/1 0:04:45 I just purchased a ported plenum from Mike at Corvetteplenums. I purchased this plenum for when I put the ZZ4 into my 89 Corvette, but would like to know about how much HP gain would I get if I put it on my stock L98 with a set of aftermarket runners and intake manifold. I have been looking at the Big Mouth intake and there runners and that is probable what I will use.I won't be putting the ZZ4 in until next spring and if it makes a difference in HP on my stock motor maybe I could put it on that motor until I make the swap. Thanks ..WW |
