Only works on the 3.4L and won't get you and huge gains... especially once the TB gets heat soaked...

I am sure it does something, but for an NA car, it's not going to really help...

For a SC car, you need to try to keep the temps down more because the SC compression further heats the intake charge and causes detonation..

The dyno "proof" made me laugh. A Camaro test vehicle before and after a ported throttled body was installed (with the bypass kit). I'm sure the gains were from the bypass and not the ported TB. Rolling Eyes

I used to to the throttle body bypass on every one of my ol' LT1 Caprices,mainly cuz it was a free mod.

I heard claims of 7 hp gain to the rear wheels,i highly dought that though...maybe one or two hp lol.

Since hose is probably $1.5 for 8" and hose clamps are like .50 each at napa, I'd say you can probably do it locally for less than $5.

Only on the 3.4L... you can't bypass this way at all on the 3.8L...

Once the engine heat soaks, you will get NO performance benefit from this

Well, i bypassed mine when i put in my tce throttlebody. Not much to it. Probably helps a little while the weather is a little cooler. Gotta watch the extremely cold winter days and like bb said, once you get some heat soak, still doesn't do much. Worth doing? For $10 or less, yeah. Big difference? No. Maybe if you installed nitrous at the same time! That might keep temps down and give you a noticable boost!

Seriously though, by the time you reach operating temps, maybe a little longer, your throttlebody is just as hot as your motor. The idea behind the bypass is to lower throttle body temps to provide a cooler, more dense air, but the effect doesn't last long.

So to recap. It's only for the 3.4.

Top swap, intercool, enjoy going faster.
