Default Fast Intake or Porting TB

What do you guys think is the best way to go, Fast Intake or Porting the stock TB? From what I understand the Fast Intake requires modifications to the firewall but will produce better results than porting the stock TB. I do like to maintain the stock apperance of the engine compartment but what is the performance difference between the two options?

I think it's a no-brainer: the intake will make WAY more difference than a "ported" TB.

I personally think a ported TB is good for nothing.

If you like the staock appearance instead of the goofy gray the FAST is molded in, then paint it. Myself and other forum members has done this, even to go as far as "shaving" the FAST and WIlson names from the intake before paint. Looks like stock. There is other threads here about this. I agree, the ported TB is , cheaper, but useless. HP costs $$$$, pure and simple.

If you decide to get a FAST and paint, here's the steps:
1) remove the gray top half of the intake using a hex wrench(allen)
2) Mask off any and all openings and gaskets if applicable,with blue painter's tape
3)sand with 400 grit and then make sure all sanding residue is gone, wipe down to clean.
4) once area is clean and dry, apply dupicolor primer gray evenly over intire area, start with a misting instead of going heavy off the bat, allow dry time.
5)Use universal flat black(duplicolor) and again, apply in a misting manner for the first application, then go heavier.
6)allow dry time, remove tape and you're done except for re-assembly....make sure those gaskets are lined up and have a good seal.

When getting paint, I got the duplicolor for plastic automoble parts. Others have suggested engine paint, but since the FAST isn't heat sink, the plastic paint is good and has a flex additive , so it's less likely to flake or scratch off, like plastic painted with engine enamel.
Good luck!!

yea i was confused as well... i think they meant to say porting stock intake versus buying the FAST intake. I just had my stock intake and throttle body sent out to ls2portworks to have ported, reason being its an alternative to buy the fast which is really expensive. but the real reason why i did it was to make sure i dont get my warrantee voided from my dealer. stock ported intake and throttle body makes about half as much power as the fast but dealer will never know anything has been done. plus its alot cheaper porting your stock stuff. i guess it all depends on how much money you care to spend and/or if you care to risk your warrantee. (which for us 2007 guys 5yr 100k mi isnt worth the risk)

I agree with what you say especially regarding the warranty, I also have an 07. I guess my follow up question is if it is worth the time money and effort to port the stock intake and TB considering the HP gains.

We think somewhat alike. I've read that to install the Fast you must modify the firewall too, that's pushing what I'd want to mess with. I'm also unsure that I'd get any big advantage by using the Fast over a ported stock unit unless I also did heads and an aggressive cam.

I'm thinking of having Cory do my stock intake too, it seems like an easy mod that would probably deliver reasonable bang for the buck. But I think that the claims I've read on CF of it giving any kind of increased gas mileage are dubious.

I would say its worth it. guys have picked up from 7-12 rwhp with porting ls2 intake/tb on a dyno. For around $350.00 thats worth it for me, i am doing a dyno tune on my car so i wanna optimize the tune to the fullest effect. Now as far as the fast intake goes you need to modify your firewall and relocate your MAP sensor so when its all said and done your spending about $1,000.00 for 12-20 rwhp you tell me. I'd do it but i will post my numbers as soon as i get my dyno tune (march 14th).

Hi guys,

There's a lot of FAST vs Ported Stock Intake threads and comments out there. There is really no comparison. The FAST obviously outperforms the ported stock intake. Its been proven over and over again. You've got to look at it like this... What are you looking to gain and at what cost?

Ported Stock Intake Manifold
+ Average gain of 10rwhp and 11-15 rwtq over stock unported

+ Complete stock external appearance

+ No mods to the car to make it fit

+ No possible dealership hassle

$ 50% of the gains for about 25% of the cost of the FAST as installed on a LS2 Corvette

+ Is a direct bolt-on that can be installed by anyone who owns metric sockets, screw drivers, pliers, and has internet access.


FAST Intake
+++++ Average of 15 to 17 rwhp gain if you just bolt it on.

- Does not appear stock unless you grind the name off and paint it black. The dealership service dept will still notice it if they have a clue at all.

- Requires install kits to make it fit the LS2 Vette
*Firewall/wiper tray cut and patch with dyno mat or the LPE patch kit.
*Also requires the fuel rail adapter kit
*Also requires the MAP wiring harness to either be rerouted to the back of the manifold or adapted to the front.

$$$ Cost at least $725 for the manifold alone, not including the needed adapter kits. Expect to pay at least $825 minimum with the required adapters.

Ported FAST

++++ Is advertised as up to 25 rwhp gain.

$$$$ Adds between $200 and $500 to the cost of the FAST and required adapters.


So... you see there is really no good comparison. They are not equal or even close. Each has benefits and costs associated. It all really comes down to your individual concerns as far as performance level desired, budget, and potential concerns over warranty.

If you're going all out for max HP - the Ported FAST is the way to go.

If you are looking for nice gains, minimal hassle, and not to break your budget- get the ported stock intake.

I've actually done both to my LS2 (FAST and ported tb). The FAST intake provides more gain...but not on a stock or near stock motor. Intake tract airflow follows the hourglass effect - remove the most restrictive element in the air path, then the 2nd most restrictive, etc. The stock tb and manifold are not a restriction on a stock configuration. Assuming you've already replaced the air filter with something freer flowing, I'd save these changes until after you've done mods that increase intake airflow requirements (e.g., cam or increased stroke).

He has a point, weakest point will always limit the maximum system output, I would do both, eliminate both problems, everything helps, some more than others, could be "the racer's edge".

FWIW, just last week we did a Fast intake, and ported TB on a bone stock car and picked up 35 rwhp! Usually we've seen 7-10 rwhp from porting the stock TB as well, just another fyi!

By Bone Stock do you mean no headers or anything else?
