You might consider getting an aluminum 4" 90 degree elbow, and a couple feet of straight aluminum pipe. You could cut the 90 in half, and position it so that it fits what you need, with the straight pipe in the middle. Make it so there are no gaps at all, and tape it together with wide masking tape. Then take it to a local machine shop, and have them weld it together for you. I think you could do it with 2 welds. I made all of my piping this way for my twin turbo setup welding it myself, and it worked real well. You would have a lot of leftover scrap, you could more than likely get away with a foot.

 

Theres some good lookin blower setups in here. Wish I had the privilege of owning one

 

Does this help? It's an old pic of mine i found on photobucket.....i can get more/better tonight if needed?

 

Not to threadjack AK, but what gains do you guys see with the 90mm J tube and TB? The swap has been in the back of my mind for a while.

 

not sure exactly, i did mine at the same time that I upgraded to a mp122 head unit, cam, and a few other things.

 

when i had a 112/370 setup, the 90mm update and tune was a very noticeable seat of the pants gain. worth it in my opinion.

 

Thank for that pic. Looks freakin great man!

Yesterday, I ordered a 22*, a 45*, and a straight hump-hose connector. Probably hit up the local Home Depot for some 4" PCV, and get some clamps locally. I plan on using my modified stock airbox with the K&N panel filter.

I had planned on swapping the 3.0 pulley for a 2.8 pulley at the same time as the rest of it. I've got track times and dyno numbers from my current setup already. Once I retune it, I'll be hitting the track & plan on posting up my results. If you want dyno results, I'll need some sponsorship.

 

Cool stuff. You run your truck with the TT and headers already? And sponsorship, I could use some of that too

 

Old picture:

 

I didn't want to use the stock Radix tube, it's inside diameter is smaller than 3.5 inches. However the stock airlid does have a 4 inch outlet! Check it out.


Here's what I came up with for my truck. Thanks for the pics guys, you all helped me decide what I wanted to do.
