This is my custom dual intake, I made this setup nearly 6 months ago but never finshed it until last week i used 2 silcone 90's cut to make a merge collector with Woody's advise months ago but ended up switching to the hard pipe merge collector later hoping to increase the velocity of the air into the throttlebody. The cool tape works wonders at the track. It doesn't prevent heat soak on the pipes but it takes extremely long for the pipes to get heat soaked and even when they do you can touch and it wont burn your hand. Where before i put the tape on it would be hot enough to burn your hands.

Haven't tested if there is any improvement at the track because its rained non-spot here on track days. I can hear more whine earlier in the rpms and a slight increase in whine across the rpm range. With the old silcone couplers i could blow in one side and feel nearly no air come out the single side, but the the hard pipe i could blow into one side and feel all the air come out the single side.

New collector vs old merge collector

Nice job....Squirrel Crusher

 

other than those ugly welds(jk), looks great....

 

Are you sure those are welds?

 

I was possibly thinking about this from sharpeproducts.thomasnet.com

 

Looks like the largest they offer is 1.9in O.D.
Not gonna pass much air through that! Not to mention all of the adapters to get it to fit.

 

On the silicon wye you will find that if you blow into the tee, air comes out the sides easily and evenly. The tee section is the low pressure side and it sucks off both sides easily and effectivley. The Super CAI power numbers has shown that ESPECIALLY below 4000 revs. THat is where it is the most important on the street and getting going on the track. There is a positive gain on the top end also, I believe 10 or better H/P.

This is a full size 3" design and also conducts less heat than the metal style. ALSO I would never talk about others welding, cause I have made a few gumball welds in my day, but they work.

BTW the coupler of silicon isolates a lot of vibrational stresses better than the straight couplers as there is more material to flex and give.

Enjoy..

 

Woody, where can we get these silicone "Y's"?

 

what's the wrap that you are using?

knappattack i believe the y pipes were custom made by woody and the pthers who have them. needswings has the y pipe but i think you have to buy the whole setup. (800$)

 

Wye connectors are custom made overseas and the delay in production is wye (he he) the dual cai took so long to release.

Check with Rob, he may sell them separately from his kits if there are any wyes not designated for a cai kit or upgrade.

Under the careful supervision of Prof. Woody, I bought a second 90 degree elbow from Rob and made my own. Just alittle time and effort pays off big time.

 

Actually I'm thinking of replacing the piece I have now with the single cast aluminum 3" piece in the picture below. It is at Amazon.com: Vibrant 2873 90 Degree Tight Radius Aluminum Elbow: Automotive

 

Sure they will sell you just the Y for $799 + shipping.

 

projectmayhem can you tell me how you relocated the power steering cooler lines? any fotos of the line relocation at the rubber junctions?

 

Hey thats a great idea i have a set of 4 of these i will make you a killer deal on. Bought them for another project and no longer need them. You can build 2 sets and sell the one ya dont use

 

I have a question for mayhem and woody. There is a difference between the two setups. One is a "Y" (large inner radius), and the other is a "T" (tight inner radius). Is that what was making the difference that mayhem was talking about? I would think that this would make a huge difference in flow, but is that correct?

Steve

 

YEA I agree i need to change the power steering line, what's the best method.
thanks woody

 

I have heard all the pros and cons to the aircleaners in the front of the engine bay compaired to in from of the radiator so don't go there. BUT
Doesn't anyone ever drive there cars in the RAIN?
When the car your following on the highway or that passing semi hits a huge puddle there is know way your not going to take in water rather than water vapor!
It's just not worth th chance to me.
Enjoy...

How did you end up making it?
