Custom pressure side & suck side piping
Is there a better way, or a way to get more air flow from the charger to the TB..custom 3" piping ....
How many people have made a 3.75" (T-Trim) pipe to feed the SC and what air filter.
Or what are some better way to free up BOOST...

Re: Custom pressure side & suck side piping
I played with this a bit and found that any imprevements UPSTREAM of the blower do far more good than improvements downstream. I build a mandrel-bend 3.5" inlet pipe for my T-trim and gained about .5 psi. Then, I removed the whole inlet pipe completely (let the S/C draw from atmosphere) and gained another >1 psi.
I fixed the whole situation by using a 5" mandrel bent inlet pipe on my turbo.

Re: Custom pressure side & suck side piping
Mike, where did you get the 3.5" pipe ? do you haae a parts list. Would this be a problem for the maf sensor going from 3.5" to 3" back to 3.5"....Did you not have an air filter on your SC...

Re: Custom pressure side & suck side piping
I bought the 3.5" mandrel bends from a local Deisel truck shop called Margot's, but you can get them here also:

When I ran without a pipe, there was no piping, MAF, or air filter. The MAF was downstream of the supercharger. I tried relocating the MAF only and found no gains.

Re: Custom pressure side & suck side piping
I had to miter 3.5 tubing to get a good fit, but I have tpis long tubes that drop # 1 farther forward, If I could have used 4 inch would have bought a y trim insted of the T I bought in sept.

Re: Custom pressure side & suck side piping
I don't know if you'll be able to find 3.75" pipe, but K&N makes filters with flanges up to 6".

Re: Custom pressure side & suck side piping
You can make a continuous 4" inlet tube from standard mandrel bends without any miters (all smooth flowing segments) It took (4) 90's to build it & it was frustrating to say the least. Connected it to the blower w/ a cobrahead.
It clears 275/40 tires along with the sway bar & fits above/behind the fenderwell/louvered undertray. No digital camera at the moment, so I cannot post a picture. It can be done, just takes some creativity.
Good luck.

Re: Custom pressure side & suck side piping
The cobrahead is right at the inlet of the supercharger, I think powerdyne uses one in there kits.
That was where I had to use all the mitered pieces right off the charger to clear the header than the steering rack and swaybar I think I used like 4 small pieces of tube all at just the right angle , the rest was a piece of cake.
