Modding the stock intake manifold (Upper not lower)

[TitaniumTT]

Theory is about as usefull as ass dyno's. I like the effort, but make it worthwhile and send it out to have the CFM tested or dyno a before and after then we'll decide. Until then all we have are pretty pics and proof that you can weld.

How many millions of dollars did Mazda spend to design these intakes to optimize the powerband? I don't think a little JB and welding will do anything worthwhile to improve it but untill it's properly tested, no one knows.

Oh, JB weld sucks.

"We" don't have to decide. Since the manifold is on MY car. I'm not trying to prove anything, just posting pics to give people ideas on doing some low buck improvements. I'm not going to spend money on dyno's every time i post pics of work i have done to prove its worth. I feel the difference in my car, and see the difference at the track. Thats good enough for ME.

And btw, top race teams use JB Weld at the track to enhance the manifolds lap after lap for test and tuning. I don't know why you would think JB Weld sucks. I love it...

You don't know if it's an improvement or not yet, don't get ahead of yourself there kitten

In this instance you should. "Hey everyone, look what I did, it should make an improvement."

Go read about Paul Yaw's experience port-matching a 12A intake mani then we'll talk.

I'll save you the time and give you the cliffs notes. Paul flow tested a 12A intake mani. Then he port matched it. Then he flow tested it. He found that he actually LOST CFM. So he tossed the mani off to the side and ran a stocker.

Assumption is the mother of all fuck ups

I spent close to $500 on an ignition system over the winter. you can bet your ass I'm going to test them against the $260 system I have sitting in my basement. If you're not testing, you're guessing. Ass dyno's don't count. How many times have we heard, oh snap, I put this CDI box on and my car pulls great and idles awesome.

Fine, what they fail to mention is they also added new plugs, wires, reset the TPS, new air filter etc etc etc. Back to back testing or I don't care. No one else should either.

Like I said, I like the idea, but you never know unless you get good numbers. What does a few pulls on the dyno cost? Pocket change for definitive answers.

Soooooo if you're car feels faster even if it's actually slower you're happy with that?

At the track for emergencies sure. I've never heard of a pro team building an intake mani with JB weld.
