Having all the bolt ons except supercharger of course, I am looking to do something for some extra gains. Have a Callaway intake, should I get a ported/polished throttle body, or have mine ported. Would you recommend it? What kind of extra can I expect. Also do I then need to retune?? Thank you all........Lenny
I'm curious, too...I actually dyno tested a ported/polished throttle body on my ls1 and I gained 7 peak rwhp and like 16 or so at the end if the rpm band.
Thanks guys for the replies. Cory, I visited your site and learned more. My question now is, is there all that much difference between having my intake ported, and/or having a Fast intake or having that ported?? Also, do I need to retune, I had the car dynotunted last year. Thanks again

Hi Lenny,
It all depends on your goals and budget. You mentioned a supercharger earlier. If you are considering one like the Paxton or a Procharger then I'd say skip the FAST. If you are staying NA... nothing is better than the ported FAST for your street car. If you're really not sure whether the FAST is worth it or what your final plans are... a LS2 Port Works stock intake could be a great fit for you. With the ported stocker you'll make 10-13 rwhp and torque more than you do now and you'll never have to worry about reliability.
I port FAST intakes as well as stock intakes. Each customer is different and has different needs/desires. That said, Ported Stockers sell 10 to 1 over the FAST mainly because of the cost and reliabilty factors.
The FAST would require an immediate retune to be sure its safe. The ported stocker would not have to be retuned at this time, but tuning always brings out the best results. I recommend you retune a ported stock intake at your next round of mods or when you decide "this is it" for mods.
Let me know if I can answer any other questions.
Best regards,
Cory

what are the reliability factors? just needing to be re-tuned?
The ported stock intake from me is 100% reliable and the dealership will not even notice or ask about it. As far as aftermarket parts go you always compromise "factory" reliability with them. They may go forever with no issue or you may be the guy that gets all the pain of failures and issues. Modifications are always a trade off to some extent. The ported stockers are minimal trade offs for the gains.

so we are talking about perceived reliability from the dealership viewpoint(meaning the dumbass greasemonkey saying something like "your ABS light is on because you changed your intake")?
I've been playing with engines for over 20 years, the FAST has no moving parts and is made of a better composite than the factory, it IS a better intake. I was just wondering if you had experience with the FAST intakes failing in some way?

Like under boost? Or when modified? The simple fact is that the stock intake is one single piece (fused together) and therefore more reliable. The FAST has gaskets and RTV to hold the halves together. A single piece is the only way to be 100% reliable. I've personally seen two FAST's come into my shop that were cracked from improper installation. The stock intake is forgiving in the respect. I've also seen 1 FAST that had a crack in the bottom panel. It just cracked... and was not repairable like a stock one would have been.
At the end of the day the FAST is an aftermarket part that performs better than the factory part... but there is always a trade off. You have to be more careful with it. Just be informed.
Well thank you for your responses Corey. It certainly seems like a pretty inexspensive mod, if I get my own manifold and throttle body ported, for 25 or so extra hp. If you were near me I would just drive in and have you do it. There are shops here that do such of course, but if I decide to send the parts out, I will certainly give you a shout. Lenny
Cory's ported stock units are BY FAR the best bang for the buck if you're at all concerned about price. If you do the intake and TB you should see 10-15hp at the wheels, and it will really wake up the upper rpm range of your engine as well.
On a side note, Cory.....I may be getting with you soon to do the intake on the Vette. I was so happy with the one you did for me on the GTO that I'm going to need to swap them out soon. Hope the good deals for return customers still apply!

Understood. Installation skill is every bit as important as quality parts
