Stock pulley is 5.5 inches.

 

Mmmm, nope.

 

Thank you very much everyone, especially Wes and 12gage.

The pulley mod is necessary for me to make up the boost drop from going through the intercooler set-up.

Randy- I was wondering how much of a pressure drop are you experiencing after installing the intercooler ? I think once I get everything set I may just crank up the boost all the way. I figured that I would probably lose between 1.5-2 psi with a good intercooler at 12 lbs of boost. I have a couple of tricks up my sleeve in relation to fuel and elevated air temps, but I hope the stock rods can handle the increase boost. Keep us updated. Peace

 

Hey guys,
Sorry about the late response on this.

I finally got a chance to upload some photos to my yahoo album
So click here:

First Harry, as you can see it is front mount air-air.
Choosing this set-up was obviously because of simplistic and ease of fabricating.

12gage, the boost loss was about 2psi, only pushing 4psi at the moment.

Harry, air to water set-up like Vortech would be awesome in keeping the boost loss to a bare minimum. It would also be awesome in cooling efficiency at the beginning but once it is heat soaked later cooling efficiency will drop down pretty quick I believe. If you are after the air-water set-up, you should probably wait for either Comptech or even when Vortech version is released?
Air to air is very simple but prone to lose boost pressure easily especially if you have mismatched and oversized set-up like mine. But I went with bigger size core and 3"piping nevertheless to anticipate higher boosting later.

The pulley hopely will be made and installed by next weekend if all goes well.
And not too far later with dyno session.
I will keep you guys updated for sure.

Thanks.

 

that looks great. the third picture does look really confusing though.

Note: i know nothing about intercoolers.

 

Randy- It definitely looks like you are capable of running lots of boost with your setup. Your setup looks pretty efficient so I would tend to think that the majority of your pressure drop is coming from the reduction in temperature of the air. This is definitely a good thing because you will more than likely be able to run a good deal of boost without fear of detonation.

 

Darn Harry, some difficult questions to answer right away.
I will try answering all your questions by Saturday.

But I will try to answer one question for now.
The core unit and each end-tanks came separate.
My fabricator had to modify the end-tanks, he cut out some portion to give more angle and make them bend little more because of the space constraint.

There are only two-types of available end-tanks from XS for my core unit.
Straight out and angled back.
There are plethora of different looking end-tanks if you look elsewhere.

The rest I will try to be helpful later.

 

Very nice setup Randy. You've just put in pictures, what my mind has been trying to visualize for some time now.

I can imagine it must've been very difficult to fabricate the bends, especially the tight radiused ones going from the bumper area through the front of the wheel arches and into the engine compartment. I've have experience with 2" piping and it was already hard enough but 3" I imagine, must be a real pain in the a$$! I imagine the intake charge is noticeably cooler, have you measured the temperature drop pre- and aftercooled? I am pretty sure you will have more intercooler than you will ever need, even if you go for the piston route and run 12psi. In fact from appearance it looks like the intercooler core is even bigger than the Speedcraft Turbo's IC which has higher intake temps and people have already run them at high boost levels without problem.


That core was intended for a Nissan GT-R, but I'm guessing that even the Silvia core at 20"X11"X3" would probably be more than sufficient for SC S2000's, and you might actually bring down the pressure drop across the core and fitment might be a tad easier.


Harry, the measurements you're guessing are just about right! The intercooler core size is supposedly 24" length X 11" width X 3" depth.
You can add 4-5" per side for the end tanks (which will effect the overall length).
