Been working for a while doing tests and track time to see if I could prove to Rob that I could get 40% more air thru his manifolds. He gave me his first set and off I went doing things like crossconnecting the intakes.

It became apparent to me that the intake was limited by the restriction in the wye pipe area. The s/c tries to blow into both intakes and the valves suck out of the head separately.
THis means that the air has to fill and be sucked out of the intake manifold, which is why Needswings make them much larger to hold more capacity.

I took the approach of crossconnecting them so that the wye pipes fed both manifolds and they shared the LOAD. THis allowed the intakes to have at least 1/2 restriction of the stock approach. Now both intakes supply air to the intake valves and thus the "pressure" stays UP better. This allows deeper charging of the cyclinders as they have very little pressure drop from the wye to the intake valve. Further there is much more storage so that the pressure does not fluctuate as much when each valve opens up on the intake cycle.

The photos show my latest crossconnect pipe which seems to allow better installation. Rob has seen the design and who knows if there are good enough results on the dyno, yall might could get u some. Now that Iam getting comfortable with the layout, I need to run off to the dyno for a spin. Work affords me little time, and this saturday were due for 102F..........Yikes

Photos should be self explanitory and informative. Its been a hoot to do and I figgured that It should be shown to all of u all. The work on the throttle body delay is getting bench time so this intake manifold project is considered mature and ready for the final exam, the dyno. Ill keep you informed as details appear. Wee having fun and doing good things.

Enjoy, Woody

History lesson: Torquing Offys Aplenty!

 

That's sort of how Porsche sets up their crossovers, though there is a valve that closes it off for low rpms, and opens it for wide throttle demands, and high rpm usage.

Once again the Professor comes through!
Dude! Yer (top) head has gotta be gigantic!
Too bad my welding neighbor is moving. I'd be all over trying this on my stock manifold!

AND yer workin' on that lousy TB delay! I'd say I'd kiss ya but FP might come along and say, "not that there's anything wrong with that"!

Great work Woody!

 

Finally you come clean! (I saw the pictures gosh .... almost a year ago until you erased them) I kept my mouth shut .... do I get a discount? You really need to be more forthcoming. Do you feel a positive difference? I'm willing to pay the price for results.

Geeee Thanks Woody.. Now you come up with this after Rob has refinished my manifolds. Squirrel Crusher

 

I know how you feel. I purchased the teflon coated dual intake and a month later the gold thermal coating came out. I refuse to upgrade the intake more than twice! (can you say header wrap) I'm waiting for the thermal coated super crossover mega HP intake manifolds.

It stands to reason, if a balance pipe works on dual exhaust, why not on a twin intake. Way to go Woody.

 

Pretty neat stuff!!!

 

the "equalizer" mod....lol....man after my own heart, always looking for HP>...... but, I won't kiss you, FP yes, Doc no....

 

Hey Woody, what're all those gizmos behind crossover tube #2?

 

That would be the fuel regulator, prototype that Rob is now selling. I design he makes, we have fun and I get the parts for the effort. Woody

 

Thats sweet!!!

 

Good job. Everyone should start paying you for the R&D

 

So what ever happened with this manifold design?

 

Bump...........
