Told you so.

I thought I'd take the liberty to make it look new again too.

 

no LTFT in RED!!

haha...isnt it amazing what a switch from Goop to JB Weld will do for LTFT's and STFT's.

 

I had one reserved (for R&D) along with everyone else and it is held up. So much for the release date. I got quite a bit of knowledge from the stock manifolds for that week I was going to offer the service and had to honor the sales to those who placed orders. With that in mind, I cant say what the gains will be on the FAST 102 manifold but there are a few things that hold true to all porting jobs.

First, there is no 'one size fits all' with any porting job. A head alters the intake runner and thus needs to be port matched. Second, the length of the runners is fixed and can only optimize ONE rpm peak. I suspect that the new FAST will make better gains than advertised, on cammed cars, because like the FAST 92, it is likely optimized for a 6300 rpm peak and not the 5800 peak of the stock cam.

Lastly, there is no such thing as a perfect casting. Just look at the castings for any head or intake manifold to see what I mean. There are seams that dont line up, casting flash, and molded in irregularities like model numbers in the plastic. There are things that will work for any porting job and, of course, rules of things you never do.

Anyone interested can get a porting video from Standard Abrasives to see the most simple of porting techniques as a base line to what makes gains for any porting job. Its a bit dated but is essentially a great place to start if you are interested. Obviously a video wont teach you to use a porting kit and specialized tools but dont do a 900 dollar intake manifold for your first project. Flow benches and specialized measuring tools are best if you have access but there are some do and donts that dont require it.

Its a great watch for the guy who likes to know a little bit about a lot of topics, a jack-of-all-trades so to speak. I think it goes for 25 or 30 bucks, at least it did many moons a go when I bought it. OK, a lot of moons ago.

Answer to your question, yes, the FAST 102 will make great gains even over a ported stock intake manifold because the stocker is optimized to 5800rpm and even ported that wont change. The FAST 102 will have the same irregularities in it that take it away from optimum as any cast product will. I suspect double the advertised gains for the ported base cam car and 30rwhp will be the norm for high HP cammed cars and Head/cammed cars. The first one will be on my car which is a LS3 head/cam/supercharged car. Airflow will be in demand.

 

I guess that's what I was trying to say when I said......

BTW- When I did the mods it was right at 100hp increase with before/after dyno. I know alot of guys with stock was getting around 340 RWHP on other dynos compared to my 320 RWHP. Regardless of what the machine says I know I picked up 100 new horses to the wheels doing the mods.

And I'll be it touch soon

i saw that the 102 manifold was comeing soon but what about the throttle body to match.. do you have any pricing for both yet.. the throttle body and the intake manifold.... thx

 

His manifold had no leak and had no deterioration of the glue because it was sheilded from oil with an epoxy paint over the goop. It likely would never have had a leak develop. The last 15-18 manifolds had this fix after JoeG reported his findings.

His tune was the culprit but didnt figure that out until the retrofit manifold arrived and it had the same tuning issue. A simple swap to an earlier tune fixed the LTFT's to perfect. You may not be aware but this manifold went on a stroker motor he just put in and it wasnt fully tuned yet. His LTFT's were nailed +50 lean. I went out and pulled off my hose plug to the front of my manifold in effect creating a 1/4" hole and LTFT's increased to +18 from zero so there is no way you will get +50 from an 1/8 inch hole in the rear.

I have repaired 28 manifolds this week and only 4 had actual leaks. Your manifold was one of the 4 and its leak was about 1/8 inch hole with the screw driver holding open. Most (90%) of the grafts didnt have a hole in the corner so none would have developed. Your's was one of the early ones that didnt have the graft covering the entire opening and this resulted in an opening of about 3/16's in the corner that relied on the glue to act as a plug. The last dozen or so proved that the purple goop w/epoxy paint sheilding it from oil was a viable fix although I like the swap to JB weld. In swapping out the grafts to JB weld, in about 20 cases, it required the destruction of the graft to get it off. It seems even oil soaked Goop holds pretty well.

None were heat damaged and I ruled out that the goop's thermal limits were passed. It was all oil damage. None had deformed glue shapes. All held the graft in place with no sign of it ever being likely it could come off. In all it wasnt the horrendous potential for failures that some make it out to be. Your manifold was 2 years old (its a FAST 90). It needed the graft to be pried off after cutting the perimeter with a utility knife and then pried with pliers.....all in all about 20 minutes to get it off. Had the graft covered with no gap, I doubt it would have failed. Had there been no oil in the manifold it would have looked like all the other 2 year old manifolds....new.

Cars running a breather can and no epoxy paint had no damage at all even after 2 years use....it was all due to oil in the intake and is why mine never showed its age after 3 years.

 

THAT IS CORRECT!!!!
I had to install an earlier tune and make some small adjustments to start
airflow to compensate for the 427!!
Guy, thanks for the help last night!!

YEAH, looks NICEEEEE!

 

You will need to use the stock 90mm TB because no 102 is available for drive by wire.

Porting pricing for the manifold will be determined by the extent of the porting but I doubt it will exceed 175-200 for the porting and I'm betting more like 150 for a complete porting. It will include a reseal which is going to be a big job due to the multiple casing parts and removeable runners. In addition to the upper and lower case interfaces, each runner now has a potential to leak air around its port perimeter and since its plastic, they will leak air. Comp likely used a RTV silicone gasket around the perimeter of each runner to accomplish a seal.

I can only guess why they again pushed back the release when it was already claimed it was shipping.....get out the RTV.

 

First are the 102mm for LS2 or LS3 heads? What is your current price and turn around time if I have "HinsonSuperCars" ship you a 92mm for mod and port?

 

The FAST 102mm is made for the LS3 and LS7 Cylinder Heads.

I think it's time to get a manifold
