Thanks!
Thanks!
We will not be offering a package with a manifold and throttle body but that seems like something that our retailers would be doing once the t.b.'s are available.

To answer some questions that were raised earlier.
1. The NW90mm throttle body will bolt right up to our LS1 manifold with the 96mm inlet or our LS2 manifold with the 96mm inlet.
2. The manifolds are made in China by a factory that produces O.E. manifolds for several automobile and truck manufacturers. It is a state of the art facility. All of the design and testing is done here in the U.S. We are a U.S. company owned and staffed by U.S. citizens. Our company also produces parts in China for both GM and Ford.

im still a tad concerned with the heat and intake temp issues that the weiland had. in testing how long did you run the car and what were the temps compared to stock...
Okay, I just ordered the polished 85mm from Byunspeed...great guys to work with by the way. The first opportunity I will have to put it in won't be until July 14. I will be swapping it out with my LS6 with no other changes. THERE WILL BE A DYNO RUN BEFORE AND AFTER THE INSTALL(same day to be as accurate as possible). I will post the numbers and probably a few pics on the 15th to see how much of an improvement it is over the LS6.

I'm going to wait to see how the LS2 design for LS1 cars works out against a FAST. If this manifold is even within 5hp or so of a FAST on a stock setup, I'll be ordering this setup. If its better than a FAST, even better then

Holy crap, DoC, you are my new best friend. I LOOOVVVE 928's. I had an '85 up until not too long ago. From the looks of it you have a GTS, nice ride. My buddy has 2. Love those cars.

i have a question if all i have right now is bolt-ons but i am soon getting a set of ls6 ported heads and a 228/228 cam from TSP would the 85mm manifold be good or the LS6 be better???

Answers to several questions:
1. Clearcoat or raw metal? We have tried clearcoating manifolds in the past and unfortunately the stuff turns yellow and peels off over time. So we do not feel that is a viable option. We have been selling polished manifolds for nine years with great success. With just a minor amount of care you can keep them looking very good for a long time.
2. When will 85mm t.b. be available? Look back through previous responses. That question has been answered several times. Right now my best guess is about 90 days.
3. Temperatures during testing? All of our dyno tests were done on an engine dyno, not on a chassis dyno with the engine in a car. As far as engine operating temperatures, they were in the normal range.
4. Schrader Valve? The factory Schrader valve is brazed into the fuel rail and cannot be removed. We provide a 1/8-npt pipe thread in the end of one rail and provide a part number for a Schrader valve available at any Ford dealer that will screw into that tapped hole for those users who need this valve.

i installed my intake yesterday on my 383 stroker. IT has a few flaws that need to be fixed but all around a good intake. it will be getting dynotuned tomorrow so will see what kind of power it makes with a larger cubed motor. its fed by stock maf and ported t.b
1. the npt fitting in rear for brake booster is covered by the oil pressure sending unit. cannot use it.
FIX used a 3/8 tee on other side to feed both vacuums
2. the way the map sensor is attached interferes with oil pressure sending unit. cannot plug both in
FIX I ran a bead of silicone around the map sensor and pointed the connector straight up.
3. the fitting for the stock fuel hose is a tad to long. wouldnt plug in.
FIX i trimmed aabout 1/16 off the end
4. the throttle/cruise cable braket interferes with the fuel rail
FIX i trimmed 1/3 inch off the side.
5. stock valley cover bolts are too tall not allowing the intake to seat up.
FIX went to autozone and bought shorter head bolts
6. you cannot use ls1 style coolant crossover tubes.
FIX bought ls6 style crossover tube.
All in all the intake is very nice. not alot of flshings. pretty smooth inside and out. I expected some flaws since it was so new. and the ones it has are easy fixes. Im happy and just hope it makes some power.
