Re: My tuner says you can't get much more

Ported stock length intakes are good for maybe 10hp and almost nothing in the quarter mile while costing $600 or more. A well made short runner is good for 15-20hp at peak and 25-30 at 7k and will cost $950 or more. As far as performance goes, if on the stock cams it will add little. If the engine has aggressive cams, a short runner will allow the them to work in their intended rpm range.

One can spend thousands of dollars and gain little in both hp and performance, so spend wisely.
