I don't defend it because I sell them. There is no money to be made on these here, too many people selling them for basically cost.

I defend it because the ONLY thing people even bother to look at are the dyno numbers, NOBODY takes into consideration the other unique features this manifold and the previous manifolds have.

Everyone gripes and moans about the price but those very same people have no problem buying expensive parts that give you NO horsepower. ooohhhhh look at my $400 billet valve covers... lol

Know what I mean?

 

Yep, I know what you mean. VA Speed got one to work great on Kevins 'vette but that took a 427 and porting to get the most out of it.

Your right about the dyno numbers, a lot of people are disappointed when they actually get on the track.

A friend of mine up here has a speed shop and it cracks me up when people spend a bunch of money for a lopey idle "I don't car if it makes more power, I just want a nasty lopey idle", that's easy money right there.

 

I agree, the 92mm TB is sufficient for almost everyone. There is little reason for the 102mm TB in most application becuase unless your engine requires more air than the 92mm can flow, then your not doing anything but trying to hurt off idle drivability. But its not becuase the 102mm slows velocity. Its because when you crack a 102mm 10% its like opening a 92mm 15%. There is a lot more air entering the plenum at low throttle position that may have an effect and screw with your drivability a little.

The 102mm has ZERO effect on power down low like people tend to assume. This isnt a carburator, it doesnt carry fuel. Its just air, the throttle body is just an air bleed to the plenum. The runners that are in the intake manifold are what create "velocity" to the cylinder, just like an idividual runner intake. The runner length, runner taper, runner diameter, etc is what makes the manifold too big, too small, or just right.

The LS3 verion of the FAST is probalby the least powerful vs. stock of the different style FAST intakes, but FAST tells everyone that its worth 14hp. I made the decision that I wanted the easy bolt on power. Plus Id rather pay and have 14hp gained than pay and have power lost with a "ported" OEM intake.

Patrick G and Texas Speed both have posted that when they tested a "professionally" ported LS3 intake that they lost power vs. the stock unported intake.

Sadly, that is absolutely true for about 7 out of 10 people....

 

Well go look up some other shops like LG and Vengeance and see what Lou (5hp/5tq is his number of a stock intake) has to say also, I am pretty sure he has done a few more of these than most people on here, PatrickG included.
One or two vehicles does not make an intake a performer or a loser. There are also several who have shown gains with a ported stock intake and some who say they lost power so just grab that proverbial grain of salt. Each intake has its supporters and detractors people just need honest numbers and that comes from several vehicles not one or two or even 5. You have one on yours but have not dynoed it or taken it to the track. Butt dynos don't get it when people are looking for advise on spending $800.

 

No, people need "good dyno data". Im not even going to get into that except to say that it requires more than $50 for 3 pulls, using a single coolant temp as your ONLY control, and always requires a cart/stand...............

 

I totally agree.

 

Would a 90 mm T/B on a 416 enough. A 90 mm T/B flows 1170 cfm 95mm is 1450 cfm a 105 mm is 1520 cfm.

 

Ill have an 87mm and dont forsee any issues on my truck intake

 

Shawn at VA Speed picked up 30HP with the FAST on my 427 but this was with BIG L92 heads that flowed 380CFM, a 107mm TB and a 4 inch downtube intake system. This was also only after porting and modifying the runners. I think it takes someone willing to really work with this intake to make great power.

Before the FAST is was running a really nicely ported L76 intake.

Just my $.02

 

I picked up 13rwhp and 15 lb/ft going from a 92mm to 102mm TB on my little cam 426 Lq4

 

Bump LOL.

I said it for YEARS before it came out.....

Thing is a dud.

It's nice looking and in a FEW bigger cubed, bigger powered cars, it has showed some nice gains. But for us stock blocked people..............
