Interchiller for SC S14`

[HANDBLT]

I am gathering pieces to put together a SC kit for my street car and want to find someone that can make an interchiller integrated into the stock plenum. Basically slice the plenum vertically and sandwich an interchiller in between the pieces and weld it back together.

Anyone ever done this with another make/model? What are the pitfalls and what would you do differently?

Mangum,

Can you share what is the package you are trying to put together ? Stock engine ? Build ? Exhaust system , target HP Dyno-Jet RWHP ?, etc.

I have been around Superchargered cars, E30M3, E46M3s and E92M3s. I will be able to share my experience.

I don't have a target HP number yet. I want to see what size interchiller can be made with the stock plenum first to see what CFM and IAT delta it will handle.

I will be fit and tested on a stock 2.3 with high miles.

Tony,


I think you are going in wrong direction with the Supercharger a choice of Fi.

I have been around for long time with E30M3 S14 2.3 Supercharger with mild ported head and it made 310RWHP Dyno-Jet STD correction.

Having the intercooler custom made and intergraded inside the OEM plenum is also terrible idea...When I rebuild the S54 Vanos on that specific Laguna-Seca E46M3 SC which has that set up, after I drove it was very disappointed for various reason. I can talk for hours about why supercharger is terrible choice....vs Turbo-Charger. Turbo is so much better from every angle you look at it. Ara's E46M3 Alpine-White in show condition with supercharger it was the following disappointment....

You will regret going to Supercharger at the end. Go Turbo if you chose Fi and you will be happy.

Why was the SC terrible out side of just the pure power numbers. Was it drivability and or engine response?

Can't argue much of that, only that superchargers are "more simplistic" a lot more bolt-on than a turbo.

But why? What are the objective reasons that a SC is a terrible idea on the S14? Remove the comparison to a turbo from the equation. If it's properly engineered, properly cooled, and properly controlled with a standalone EMS, what are the downsides?

just meant cant argue a turbo is better. i dont see why it would be "terrible". That's a bit of an exaggeration.

Tony,

Even if current Formula-1 engineers to build your project it is still going to remain Supercharger....

There are several major downsides on Supercharger design and I am lazy to describe...I can sent you my phone number call me and easier for me.

You aren't answering the question though, and I want the discussion to be here for all to have and see. I am not comparing a SC'd S14 to a Turbo'd S14, I am looking for reasons that a properly engineered and build SC'd S14 is bad. It's 300hp+ and much more torque (not down low like a turbo of course) but it retains the personality of the S14.

Adam,

When you drive supercharger and face its negatives and then you hop to Turbo set up then you really come up with the word "terrible" I have been around E30M3 S14 E30S52 E92S65 E46M3 E39M5 with supercharges....have driven both Turbo and S/C and its obvious.

I am very picky on certain things....perhaps you will never notice them and you will be fine with them whout knowing them they are there..

The most powerful supercharged BMW engine I was in driven with anger was Artin's E46M3 SC put on E85 Dyno'ed at 680rwhp....Same car build with Turbo will be faster for sure....after he spent so much money he was not happy with how fast the car was and Sold it and got a Turbo Car !!! and said never again S/C system...

I get it...its not as good as a turbo. It doesnt mean it's terrible lol. It's all compromises. Not everyone is just after the most power. Some people prefer S/C and it's style of power.

I am not after ultimate S14 ragged edge power. I have that already

Either 700rwhp or 100rwhp principle is the same.

One will never get away from its given design...

If one is doing Fi why not the proper one....?

Some people prefer S/C and it's style of power

Properly put turbo set up also outperform as you call it "style of power" which one can't adjust on S/C

Tony,

The list is so long that I am just lazy to type...

But yes as you call it engine response is one from the long list.
