Xorro, your car'z got a 4-2-1 header on a stick?

 

You know Xorro.. I have been thinking on that I/C set up for the Alpine S/c. The Saturn Redline uses a S/c bolted to the intake.. they fitted a larger than needed intake that incorporates cooling "tubes" to make something similar to the Alpine "aquacooler" that the v6 gets..

Like the aquacooler.. they run a small water pump to a front mounted cooler and then hoses to the "cooling tubes" to chill the compressed air. What I need to do is get my hands on am Alpine intake and see if it can be modded the same way,

 

I know its old but had to throw my two cents in too since I have a s/c as well. After many months of tuning with Alpine the current results I have with 4psi was 163+whp this is just with a Random CAI. Direct from Alpine they recommend 4-2-1 headers for this kit to keep some back pressure for trq. When I get back from Germany we will see some good numbers come out of this kit once I dump some money into. The s/c is fun the only drag that I feel is I am still running stock manifold stock pretty much everything. As far as the intake manifold :
1. Theres not enough room to put a aquacooler in there even if you did it would have the same cooling affect of blowing air through wet screen window. It won't be enough.
2. Only options are alcohol injecton, water injection or nitrous kit(I have a kit sitting in the garage hehehehe)
3. ANother method I have seen is mount the s/c upside down on the exhaust side and build a manifold and tubing for a i/c then to the stock intake manifold. Its alot based on the Miata's s/c kit design. Can throw in more boost safely. Run an aquacooler or regular i/c.

 

YES kit.......4-2-1 headers are generally BETTER for S/C...mainly b/c S/C's actually create more torque (in general) than HP.


who is it thats got the CO2 kit for thier intake????

that may help cool things off before the air is compressed thereby reducing the initial intake temps........

YES, i know it will still rise some but colder air going in almost always will result in cooler air coming out too.....

 

I had wondered about how to do that.. mount the SC on the exhaust side.. the problem I had.. how to route the belts, that side of the engine is VERY close to the side of the car.

 

The problem with the crappy ass SC that alpine sell is that its a Roots Type blower with twin screws that compress the air. These type of SC are good for INSTANT boost all the way from about 1200-1300 rpm to redline. These SC are also good for low end TORQUE. Problem is they sit on top of the Head and you have to replace your Intake Manifold. Also theres the problem of how to coll down the intake charge since the SC is right next to the intake runners.

Now theres the other type of SC which is basically half a turbo, except, instead of running the compressor off of the energy of the exhaust gases you turn it by way of a pulley; these are the Centifugal SC.

This is what my 5.0 looked like when I had it. :twisted: 8O


As you can see; with a centrifugal SC, you can run an aftercooler and it would be much like a turbo system. Also with this type of app. you can run about 15-20psi with the right pulleys. Also the turbo lagg is about 40% less that a typical TC system at the same boost.

Now when Vortech, ATI, or Paxton decide on making a SC for the Beta, I would seriously consider it over a Turbo.

 

Ripp mods builds a vortech system for the v6. I wish they would put one together for the beta...
