What about TQ #'s

The more your engine can breath ie cam and heads the more you benefit from the ported TB.

Yeah, I think the real benefits of a ported TB won’t show till the heads/cam level. Just like the LS6 intake really shines once you’ve got heads/cam.

 

I could tell a differnce in the way my car responded after porting mine, as far as HP, I would say 3-8

 

Definately worth it if you can do it yourself. I ported mine in my garage in about 30 minutes. I am not good at "feeling" mods, but it's common knowledge that opening up the passge for air is going to produce more power.

It does work, so more importantly now is a procedure or write-up to do this. <img src="images/icons/smile.gif" border="0">

I had my '98's ported and I'm going to port the new one as soon as I get a dremel <img src="images/icons/smile.gif" border="0"> definatly worth it

 

Every little bit helps.

I ported mine and couldn't tell a difference, but I have a lot of other things going already.

 

I've read of too many problems with it. I'd like to do back to back comparisons, switching one out with a friend and be able to run a wide band on it.

Then, and only then if it worked, would I be convinced.

 

I ported my TB and did the Fernco mod at the same time, and noticed a difference.

 

We picked up 5rwhp/4rwtq peak and up to 8rwhp in the midrange with a ported TB on a cam only car.

What kind of problems have you heard?

 

OK people, how do you port your TB? What sections should I look to remove material from? Details?

pinging, too lean at WOT
buy auto tap -- should have one anyway though
MAF-T
fluctuating A/F at WOT from off-idle to shut down
hard to tune
trims fluctuating greatly to adjust.

you can't just stick a ported this or that on the car and expect it to produce + results. you have to look at the whole package. same thing we had to do back in the LT1 days. was a 58TB ever too much for your mods? yes, 1050 mono-blade? yes.

put my 58 on the car before i had the 396 done. it was too much for a hot-cammed/header/bolt on car. ran awful.

Be aware is all Im asking of you. It is a terrible thing to make changes and have nothing more than bought problems. make changes on data. Hell, borrow one and see what it does.

Hope this adds some perspective.

Supposedly 7-8rwhp. i noticed a difference in putting one on my car.

 

I saw a 4rwhp increase on my car with just bolt ons.

 

at our local dyno day a friend put on his 80mm BBK and lost 4 HP.

 

Maybe someone could do a write up on before and after porting the TB. Dynoing and using autotap.
