A boost gauge/vacuum gauge will not tell you anything unless you have a boosted system... turbo or supercharger. If you do not have one of those, then your engine is only creating vacuum, period.

In no way will that gauge give you an idea of power gains without boost...

I'm not knocking on your install or write up, but those types of mods are really only beneficial to high revving vehicles, that have a powerband beyond the Jeep motors. i.e. my honda prelude redlines at 7500 RPM's. Peak power comes at about 5000 RPM's all the way through to 7200 RPM's.

Mods like that in fact do increase power, regardless of what others might think, but they are just not as useful in our Jeep applications as they are in others. My 2ó


Ok, next time go to the site and at least look at the pics...there are 8 Pix that show the Supercharger on the Jeep.

Yes in fact you are able to ascertain power gains using "that gauge, you just need to understand how to read and understand the gauge.

I would be the first to say that high rpm engines do indeed have more gain, however any engine will see some gains if you reduce the intake air temps...which if you had also read you would understand that was the intent.

You guys sound like house shills for Big Jim...I would think a guy from Arlington would know better...maybe its only us guys from Colleyville <img src="/forums/images/graemlins/cheers.gif" alt="" />
