Nice nice numbers givin stock heads!

I just purchased a TR-220

BTW, that TR-220 was advertised incorrectly on the Thunder web site. Its actually .553" lift

There web site now reflects the correct lift #.

BTW, do you believe your "ported" TB added any power? I was thinking of purchasing one, but they have the exact same throttle plate size as stock. I keep saying they should call them "smoothed" and not ported. Anyway, are they really worth the bucks in your opinion?

Thanks,
Ron

Bret Bauer over on LS1.Com was pretty convincing that these ported TBs do in fact make some power. Maybe he is right.

Again, are you happy with yours?

On the same setup I got 8hp with a ported TB.

To be honest I didn't dyno before and after the TB, and I couldn't tell for sure if it pulled any harder. It did however change the throttle response and low rpm driveability. TR was sharper, and the darn thing will not load up or shudder if you let the rpms drop. It drives fine at 50 mph in sixth (stock 3.42 rear) after the TB. So I don't know for sure, but comparing stock and S2 side by side, it sure looks like the S2 would cause far less turbulence. I saw a post from someone last night that had an '01 M6 with the exact same mods that I have except for the S2 and pulley, and he dyno'd 370. I would spend the money over again.

Kimchee and Rice is corrent, the cam card says .553.

K & R .. The ported TB's really are ported. There is a ridge just before the throttle blade that gets hogged out. I did my own, using the coffee stirrer as a template. When you get done,and the coffee stirrer goes thru the ported one & then try it on a stock one, you can really see just how much they are ported. As for HP, I don't know but it can't hurt & it definately improves throttle response.

Nice numbers. I'm thinking about getting that cam as well. Do you think the TR224 would've been better or is this one just right for the street?

I wish a set of heads were in the budget, but I have spent my toy money for a while. I am very happy with the way it pulls now <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Gary98Z - According to Thunder the 224 cam will make about 10 hp more from 5K up, and I presume it would give up a little below 2500. The 220 cam is extremely driveable, basically around town it drives like stock with a slightly more choppy idle. No codes with stock tuning either.
