oh, and not to point out the obvious, but there are ALOT of low production injection molding companys worldwide. if someone with the inital financial backing was intrested and capable of designing a manifold, it could be made and massproduced easily. and even cheaper if nylon66 or some other sutible but cheaper then AMODEL A-6135 PPA composite was used.

 

I was gonna say the same thing, taking a Polymers and composites class this semester

 

Hogan built the sheet metal manifold for my engine only after I sent him the actual heads to be used as well as the finished measurement for block height. When it arrived the only problem was clearance between the throttle linkage arm and the forward end of the fuel rail. This issue was resolved by spacing the throttle body forward so that the stock linkage would clear the fuel lines. I've been very pleased with the fit and performance.

Yes but how much did it cost?

 

If your question is relative to moving the throttle body forward, the answer is "next-to-nothing." I machined several aluminum blocks as spacers and sandwiched them between the throttle body and the manifold moving the TB about two inches. They actually enlarged the size of the plenum and I viewed that as a plus.

If you meant to inquire about the cost of the manifold, it was about $3K. Going fast costs always costs money. Situations such as this one call to mind the Harley-Davidson commercial. "Harley? Dinette set? Harley? Dinette set? Easy choice, dinette sets never set records.

Well, if the aluminum and machining were free, "next-to-nothing" works. If you need to have the spacer made by someone else, it could add 3-5% to your quoted manifold cost. But, as you said, speed costs $.

 

The aluminum and the machining were literally, "next to nothing." But, at that point in the development of the combination another hundred bucks or so would have been negligible.

I really don't know how well a Hogan manifold would work on the street. I wouldn't consider it to be a "dual-purpose" type part although it might be fine.

Believe me, I considered other options but they always came up as a compromise. Composite materials could present some desireable features if the molds were manageable. My mold-maker friend reminds me that anything can be made if you want it badly enough. In the end, people might not be any more willing to spend $1,500 or so for a plastic piece than they are to spend $3,000 on an aluminum, fabricated one. Usually, about 10% of enthusiastic shoppers turn into buyers and since the LSX will probably push the LT1 off the "A list" fairly quickly I have no desire to sink $20K or so into R&D for a part that no one wants.

In summary, I'm reasonably pleased with the performance-per-dollar I got with the Hogan.

If it was reasonably priced (upto the price of a FAST plastic intake). I would be the first person on the list to buy.

I will start a new thread in LT1 tech with a poll to see how many serious buyers we would have.

 

Got any pic's of your intake?? I am thinking of having a local shop do mine.

 

Chris,

Your request came at a bad time. Just before reading it, I closed the trailer in preparation for heading to the Winternationals. About the only way to shoot any decent pictures of the manifold is when it's out of the car. Since most of it sits under the windshield, about half-an-inch below the cowl, there isn't much to see anyway. The top absolutely won't come off while it's in the car but you can see pictures of fabricated manifolds at numerous places on the Internet. I'll see what I can do after the next couple of races are over.

No Problem...Good Luck at the National's

 

Guess I’m a little naïve, but I was thinking they were about $1.5 K. Ya well…….. How fast do ya want to go? How much money do you have!

Now the question comes up….. How much power did you pick up and where in the powerband did you get it? What where you using prior?

I’m considering one as a dual purpose. I love to play with my car on the street!

 

Denny,

There was no "prior." The car was scratch built to be an NHRA Super Stocker to take advantage of a very favorable horsepower factor assigned to the LT1 for class racing and the Hogan is the only manifold I've put on it. The car holds the SS/IA record at 9.74 @136.60. It pulls strongly up to 8200 and might go higher but I run out of track. The limiting factor on the combination seems to be in the area of air flow since the rules require that the stock, 48mm throttle body be used and the intake runners are limited to a maximum of 175 cc, the exhaust runners are limited to 68 cc.

The manifold pictured in another thread with the URL <http://home.wideopenwest.com/~squinn0039/ltx.html> looks very promising. If you have a lot of cam, you'll want the biggest possible plenum in order to pack as much air as possible inside.

Good luck.

Thanks....... very useful information.

Actually setting up a smaller cam (240ish/.600/110 range) but larger head intake volume (220cc) on a 398ci block hoping this will work. A set of TF heads are currently going through their second porting/re-valving session along with a LT4 intake and believe it or not…. The headers are being welded and port matched also. Once running, I'll fine tweak the cam spec’s based upon power band and how it does on the track.

Certainly got room to grow and an intake sure is on the radar screen as being an area for improvement.

Appreciate your insights and congratulations on setting a Super Stock class record. You’re playing with a few boys who know a few tricks themselves. Certainly a very significant accomplishment.

 

Well from the results of the poll I posted in LT1 Tech, it looks like most people think $500 is a reasonable price and wouldn't pay more than that.
