^ The LS6 intake is just a one piece, so it's unlikely to have rough spots. The FAST intakes are left slightly "Cast-rough" so people like us can massage them to fit many different applications. The ridges come from when pieces are mated together. My 102 base fit my 243 heads almost exactly, so I didn't need to do much there, but the runners had a nasty lip when mated to the lower. So I took a cartridge roll to it just to smooth it out. Not to mention the sharp edges on the runners and other pieces inside the intake. That's all it really needs, until you start port matching. Unless you have a flow bench, I really wouldn't try to straighten any runners out.

Mamo and Vengence have a lot of experience with this stuff, so there's a reason why they do what they do. A piece doesn't need to be "hogged out" to increase performance.

you guys think fast/wilson is gona cast them with that wedge if it was somthing like 15 or even 5 whp. Theres alot more to the manifold then that wedge. The runner size and taper are gona have somthing to do with gains. On all diffrent sized motor and heads setups. And it not gona be just removing a wedge and bouncing a sand roll around the end of the runner for a few seconds and claiming its been ported to "work"

Sounds like a challenge for GM high tech performance magazine to me. Let us all write the editor?

I did not mean to imply that at all. I was just pointing out the confusion people seamed to have that the OP's ported intake "just had some body rough it up a little" and "didn't remove any material".

I assume the wedge was in place so that the air velocity is high enough on a stock car to help keep mid rpm power in place. It's too large to be a casting flaw.

If someone wants to send me a non ported 92mm fast intake I'll put it up against my vengeance ported 92mm and show the results on my car back to back on the same day on our dyno.

I am interested in seeing it myself.

For a hunk of $5 plastic being sold for nearly $1,000. You would think you wouldnt have to go through all that "extra" work.

So what did everyone that disassembled their FAST intake torque the 3 front and 3 rear short bolts to when they reassembled it, and did you use blue loctite?

You can't expect to get a lot of time invested for a $150 "port match", so I don't see what there is to complain about. A valvejob on a set of heads typically runs only $200-300 but that's where most of your gains will be found.

So what gains is your porting over a none ported one?
I can see you want to say its NOT been proven to outperform a $500 port, How much DOSE your porting gain for $150?

You can say the same thing about a set of cylinder heads that cost 2 grand. It's just part of the game.
