I have an Skunk 2 IM on my 96 Lude. I want to get a new throttle body. I've decided to go with EricsRacing 70mm TB (I will have to have the IM port matched). Do you think I will lose power with such a big TB? Any input is appreciated.

 

not at all. i have an STR 70mm on my ported stock manifold and it's great. good for my big JUN cams.

 

Well - correction, if he doesn't have any extreme cams or other mods, he'll lose velocity won't he? I personally would think that a 70mm TB would be way too much for I/H/E.....assuming thats what he has. But if you have other mods, go for it.......

After you do the manifold, get the head port/polish /maybe an angle job done.

 

70mm str works grate for me, lots of head work with cams.

 

Thanks for the replies. 70mm it is.

 

What mods do you have? If you don't have head work and cams, you'll be actually losing power.....list your mods.

 

King Motorsports P&P, WebCams, Supertech valvetrain for the head. The bottom end is about to be stroked.
