Plwtwo Posted January 29, 2004 Report Share Posted January 29, 2004 I was at Competition Cams yesterday, And asked about their FAST intake fitting on our trucks. They will fit!!!!! But there is/or may be a vacuum hose that hits the throttle body movement. For those of us who have side mounted SuperChargers it shouldn't be a problem, if the throttle body has been relocated. It looks reallly good, but it is a polymer material. The way around the clearence issues would be to use a throttle body spacer, like the Ford 5.0's use, like the Poweraid product, that is useless otherwise. And they should start shipping in Mid-February. Link to comment Share on other sites More sharing options...

BigTex Posted January 29, 2004 Report Share Posted January 29, 2004 Several LS1 shops have already gotten some in. Results have been mixed. I haven't seen any supercharger results with them though. Some NA cars gain 10 HP over their LS6 intake, some gain 3. Link to comment Share on other sites More sharing options...
Plwtwo Posted January 29, 2004 Author Report Share Posted January 29, 2004 They had three engine dyno's set up with these on Camaro LS1's , and a Vette Ls1. Their numbers were wide, also. One was a claimed 19 Hps, one was 8 and I believe the other was in the 11 range. Link to comment Share on other sites More sharing options...
scandore Posted January 29, 2004 Report Share Posted January 29, 2004 If CHP reported that the Stock intake manifold on our trucks flows better than the LS6 intake and LS1 does not flow as good as the LS6. Would these fast intakes even flow better than our trucks. Link to comment Share on other sites More sharing options...
tbyrne Posted January 29, 2004 Report Share Posted January 29, 2004 Here is some info for the FAST intakes and throttlebodies - ENGINEERING FAST™ assembled a team of some of the best manifold experts in the country, including Keith Wilson of NASCAR and NHRA fame, with the goal of making the finest new manifold ever built. We developed a unique three- piece design that allows you access to every inch of the manifold. The middle and upper shells can be changed to allow for additional engine modifications, like a FAST™ 90mm throttle body. Runners can be match ported. They even included witness grooves to indicate how much material you can remove. They also engineered in unparalleled performance. Now you don’t have to sacrifice low end torque to gain horsepower! To make the LSX™ a true bolt on product, it is made to fit under a stock hood and uses all factory hardware, fuel lines and linkages. However, the runners were redesigned to increase velocity and volume of airflow by moving air more efficiently. The LSX™’s longer, tapered runners allow it to gain top end horsepower without sacrificing low-end torque. With 25% more plenum volume, each runner is allowed to draw from less turbulent air. As the air enters the runners at the bell mouth, the angles are redesigned for better runner inlet transition. The throttle body is specially angled for improved plenum flow. For all of these reasons, you can expect up to 20 more bolt on horsepower and 15 more foot-pounds of torque**. As if increasing horsepower & torque weren't enough, the team then designed in some special features to allow you to make further refinements to your engine. Special bosses are designed into the LSX to accommodate nitrous oxide nozzles and these bosses are placed at optimal angles. We've already mentioned you can port the LSX, but there's even a place for a burst panels to be installed to help prevent engine damage caused by nitrous backfires or boost pressure overload. ADVANCED POLYMER The team decided that even though using an advanced polymer material would be more challenging, the benefits far out weighed all other materials. They selected "Amodel" because it is 20% stronger and 25% stiffer than the nylon used by the O.E.. It is also a remarkable 127% lighter than aluminum [11lbs. vs. 26 lbs.]. Even more important is the heat advantage. As an engine heats up to its operating temperature, a metal manifold absorbs that heat, which in turn causes it to preheat the air that enters the cylinders. This process, called heat sink, robs you of horsepower. Amodel does not absorb engine heat but instead acts as a heat shield, allowing much cooler denser air into the cylinders. The result is a lighter, stronger, stiffer manifold with built in horsepower gains from the material alone. APPLICATIONS The LSX fits all GM Gen III engines. It is available to fit stock throttle bodies or for FAST 78mm and 90mm throttle bodies 30-54001 F.A.S.T. LSX intake for the 78mm throttlebody $789.99 30-54003 F.A.S.T. LSX intake for the 90mm throttlebody $869.99 The 90mm version is only recommended for stroker motors. LS1/LS6 Throttle Bodies Available As 78mm Or 90mm FAST™ used the latest modeling software and test equipment available to produce designs that yield the maximum flow per square inch of cross-sectional area. All throttle bodies are machined from billet 6061-T6 aluminum on precision CNC machining equipment for consistent quality and light weight. CNC machined from 6061-T6 billet aluminum Brass throttle blades to control vibration and reduce thermal expansion Throttle shafts are machined to decrease their cross-sectional area, leading to increased flow 30-54016 F.A.S.T. 78mm throttlebody $coming soon! 30-54008 F.A.S.T. 90mm throttlebody $coming soon!

383ss Posted January 29, 2004 Report Share Posted January 29, 2004 again, I've heard this both ways. I'd like to hear numbers and a final answer on which flows better the truck intake or an LS1 intake. An ls1 won't fit unless you have a car style water pump and fab a relocation bracket for the tensioner. I'm sure the FAST is the same way. Link to comment Share on other sites More sharing options...

m396 #00-011 Posted January 30, 2004 Report Share Posted January 30, 2004 Yeah, the data so far doesn't look to promising. I would like to see more data on the truck intake flowing better than a LS6 Link to comment Share on other sites More sharing options...
