are ported throttle bodies worth it?

**01A4Z28** · 02-20-2011, 03:51 PM

just wanting to hear some opinions on ported throttle bodies, and are they worth it?

**bills98ta** · 02-20-2011, 05:07 PM

My Opinion... A ported 78mm TB, is still 78mm.....

with that said, what size do you recommend cause i am in the same boat

**bills98ta** · 02-20-2011, 05:45 PM

If you don't want to upgrade the intake ( yet ) , they make adapter spacers to fit 80mm TB's. It will increase the air velocity. I ran one years ago with a 80mm BBK TB, and it worked great. ( long time ago ) LOL !!!

Ok so what is the biggest I can run on my ls6 intake without the spacer

**bills98ta** · 02-20-2011, 06:01 PM

You might be able to port the intake to 80 mm, but I'm not sure... My last intake was a LS2, which is a 90mm stock, but you need to upgrade the fuel rails and use the larger o-rings on the injectors... Here's my latest intake mod I did over the winter !!! I'm still tuning it for this coming race season !!!

Oh ya, the 1" spacer will help your top end some...

Thanks for the info

I like ported TBs...even the small ones. Shaner makes some nice ones.

i guess my biggest question is does it make that much of a power gain over a stock throttle body?

Will it help, yes. Can an exact power level increase be told, nope. When I ported my stock TB, I noticed a nice improvement. Im ready for FAST now

**01A4Z28** · 02-20-2011, 07:11 PM

got it i was just curious and thanks for the in put

**sjsingle1** · 02-20-2011, 07:58 PM

i like my egay PP TB

**zmg00camaross** · 02-20-2011, 09:06 PM

I did notice throttle response, And I expected nothing. And Bill Is that a vic jr or sr? could you retain the wipers if you tried? O also got the shaner S3 TB. Gift from the GF of that time

**0verkill** · 02-20-2011, 09:37 PM

you are not going to feel it or see much just from it. its more of a support mod. any thing to help air flow is going to help. when you put it with a set of headers and maybe a cam then its going to help that much more. i have one from shaner and love it. i have the s3. if you call to talk to him make sure you have a good amount of time he is a talker. the spacer is pointless on are cars. just my $0.02

**5150** · 02-20-2011, 10:38 PM

**98maro** · 02-20-2011, 11:24 PM
