My setup is competely made from scratch, as for the intercooler it doesnt matter. Find a intercooler with the measurements you want. Ill get some pics up of how my setup is now once i am home. Its cleaner and works better. I can tell you this, dont plan on using any silicone elbows. They wont work, must be metal.

 

What all have you done to your kit? I saw your last thread about porting something but I didn't read all of it. How much power are you putting down? I think the whipple is a great blower.

I am going to stroke my engine to a 408 this summer and I want to try to max out this blower and see what kind of power it makes, after that I am going to have a 3.3 whipple made to kit into the truck. I am going to aim for over 600-700whp when I am done.

 

The inlet needs to be rebuilt & expanded to at least 90mm so its not such a restriction.Mine will be a 102mm after today also keep in mind that my tb is no longer on the compressor inlet.It is on the intake manifold.
The only porting I did was to the heads and little bit on the outlet manifold of the compressor.If you really want to get some more power out of that thing you need more belt wrap.I discarded the adjustable pulley on mine.I believe you have a 6.5"crank pulley that has to be changed to at least 7.5".Thats one other thing I built from scratch.The crank pulley also needs to be pinned.

What size pulley is on your compressor?

 

So you bored your throttle body out to 102mm? I have been thinking about relocating my TB to back to the stock loacation. I already changed my crank pulley to a 7.5 and had it pinned. I don't remember what size is on the blower. I am making 10psi right now with my intercooled setup.

How much power are you seeing out of your setup? What injectors are you running?

 

How about posting up some pics of your throttle body mount location and your setup in general. I am thinking hard now about ideas.

 

What's the advantage of the throttle being downstream of the blower? How do you make the bypass work?

 

Well having the tb down stream enables you to blow up the inlet big as you want.Which has been a huge iat factor for thes compressor.Also throttle response has increased dramatically even with 8.8to1 comp 4.8.

So far the biggest problem been it builds boost too fast.It also wants to build boost under part throttle.So it is a work in progress for sure.Today I opened up the inlet for the blower little more (not quite 102mm like I said)more likie 96mm give or take.Also took the bypass off the outlet side of the compressor and replumbed it into the cold side piping before the maf.Had to rebuild the bypass cause it had a small rip and wouldn't hold vacum(probably contributed to some of the boost problems).Didn't quite get done yet though.I will post picks and get a video of it soon.Like I stated before With ambient temps of 60-70.I have not had iat temps over 100 yet no matter if I beat on it or just stop light to stop light.Also it dosent drag the motor down anymore than it used to being open inlet so mpg's still seem the same which is about 18 give or take.

 

Isn't it as loud as heck? Isn't it as loud always as mine is under full throttle?

 

That's one other thing im working on but I think by running bypass off the cold side of the intercooler its going to help.Also the sound is probably going to be ok for me either way.That's why I will also have a vid up soon.Even if its too loud there are ways to subside the noise.So you know the way I have this setup has been done couple times by oem's jus not with the 2.3l twin screw.

 

I know mine is loud as hell, pretty loud then gets quiter at around 1" vaccum then starts getting loud again. The faster I spin it the more retarded the sound is. Right now mine is at 11psi, I have some smaller pullies but have not put them on yet.
