On my combination The T/A was about .05 ET and 1/2 mph inprovment over a stock iron Q-Jet. I did a doc mod iron Q-Jet with the center divider left alone no improvement. I ran a 1 inch 4 hole spacer with a 1000 Thermoquad on all the intakes. My best was 12.84/103.5 with the T/A no porting at Beaver Springs last October on a good day. The intake is about a 1/2 inch taller than stock. Being aluminum will be easier to port later on.
well that's not very encouraging , so to spend $500 for 1/2 mph, seems like there are better ways to spend your money. it almost seems like they don't research and development this at all. or to make it any better at all just kept the old mold and turn it into aluminum. thats a lot of money to save 20lbs.
I think it's good for the guys who want to run a Holley no more adapters. Most.uead Q- Jet intakes are north of $300. Well other combinations may have different results.
thats great and I agree, but still minable gains for that amount of money, thinking maybe I should cancel my order, I was really hoping for something to get my teeth in. I have called them today and they have no data on what they have made, none thats hard to believe you sunk this much time and money into this and you have no idea what kind gains this well make for buyers of this intake.
good point easier to port. be nice to have flow numbers stock vs TA on the same flow bench. Tom what was your 60 ft and 1/8 mile et/mph. thanks
So did I. I have two Cast Iron Quadrajet manifolds in stock; if I was going to go that route I would first install the cast iron manifold and get it running properly before I went for the Aluminum manifold.
the best heads in the world won't be good with an intake that will bottleneck the air flow of the heads. intakes do matter
the intake should flow at least 15% more than the heads. so a good ported nailhead flows 220 cfm at .500 lift. so a good intake should flow 253 cfm.
If it gets rid of 20 or so pounds, I'm good. Edit: I received my TA Aluminum manifold yesterday. It looks fantastic and weighs exactly 19 lbs on a very accurate scale, including the metal heat passage plugs that are shipped in a separate bag.
Note on the TA Intake manifold - I am in the process of installing my new TA Performance manifold. I suspect that it would be a straightforward bolt-in swap in the stock vehicle, but Nailheads didn't come with an '82 Chevy pickup. The casting is just enough different from stock, that my throttle linkage will not bolt to the Aluminum manifold. This is not in any way a criticism of the TA manifold, but if you are using anything other then stock throttle linkage, you will likely have to do some throttle linkage modifying. Just a heads-up.
I have been having trouble with photos in this computer, Tomorrow I will try to get a couple of photos and have another session with this computer. It was doing fine until Windows did an automatic update. It is pouring here in not-so-sunny SW Florida today, so I really can't take pictures today. The issue is that the new Aluminum manifold is a whisker taller then the original, and my homemade throttle linkage bolts to the intake manifold bolts, not the carburetor base. I will have to make two linkage brackets that are a bit taller then the ones that I have. Not a huge deal.
