Default ZZP Milled TBody

I was looking to see what else I could find for our cars and found this. I ordered it and it look like a nice piece. And yes, it does fit fine. It has an 8 pin connector already too. This one lets the TB open 100% as ours from the factory only opens 88%. Should be a good add on especially with headers.

Mike not sure of your thinking here,

This is what I read:
This is a bolt on larger throttle body for your LSJ. By feeding your blower with a TB that is 7.6mm larger than stock, parasitic loss is reduced, HP is increased, throttle response is dramatic. The stock TB is 67.4mm and the stock blower opening is 70.5mm. The LS4 TB is 75mm.

It is smaller than what we have, VE efficency is achieved at 80% +/-2 on our LS4s. It has been proven that the turbulance/backpressure created at the non 100% opening of the butterfly is indeed benificial. Who knows maybe I can learn something here, please post your results.

I asked a whole lot of questions prior to purchasing it. It is not smaller than what we have now. It is an actual LS4 tb that has been modified for increased flow. If you look at the drop downs, if you own a LSJ (Cobalt, Ion) then you would need an adapter plate. Since we already have the LS4 we do not need any adapter. All the rough spots are taken out. It looks real nice. I'll let you all know how it goes. I may install it later today. Also, I already have a throttle body spacer (spiraled) that creates turbulence after the tb anyway.

I know, I told Zoomer that he should put it in his Grand Prix section as I found this totally by accident. Nice tb for the price. I am always on the lookout for new products for us.

Let's get this on and see how it does! LS motors have seen dramatic improvements from Ported TBs.

AG,

That's what I figured for 100.00. I'll go throw it on in a few and let you guys know.

Well, it's on and the throttle response is better. I think it was worth the 100.00. Plus, there isn't any core charge which what really made my mind up.

After replacing it I decided I am buying a catch can too. I think we would benefit from that as well.
