I'm trying to figure out if I want to a pulley and ported tb. I just installed Texas speed LTs a vararam cai and took it to have it tuned. My questions are do I need to take car back to have it retuned for the ported tb and why the horror stories putting a pulley on? Guys are saying the pulley is eating up the ac belt and what's up with the stretch belt? What tool is needed for that?

I haven't heard anything about the UD eating the AC belt. The tool is a $10 piece bit from what I have heard you can get the belt on with a regular screwdriver.

Oh I have also heard that porting the TB on Ls3s is worth nothing in HP or TQ.

I have a few thousand miles on my Powerbond underdrive pulley. No issues.

Bo White ported my TB.

Thanks did you have to retune after the tb? Bo white is who I was going to send my tb and I was also looking at the same pulley from scrogging dickeys

Well I just sent my tb off for the porting to be done but I really think I'm going to hold off on the pulley. That just seems like a lot of work and money for 5hp. By the time I buy the belts I will have about 275 in a pulley. I will hold off on pulley when I do a cam swap later.

What is the cost of porting the TB and how much will you gain? I haven't heard of much power being picked up with porting the stocker.

Im not really sure. Ive heard some ppl say its been dyno proven but for 100 bucks its just something cheap and simple

Bo dynoed his TB, it picked up a little on the dyno. Felt like I had better throttle response too... quicker.

How can I contact Bo White about throttle body porting? Is he a forum member or a sponsor?
