I was thinking about possible FI options and I really like the idea of a twin screw positive displacement type blower setup on the s2k. I am only really looking for 300-350whp, and the linear power-band would be great. Plus i think if done right it could be a pretty clean package, not to mention the sound. So while poking around I found myself looking at k-series supercharger setups, and I wondered if anyone had thought to adapt a k series system to the f20c.

I was thinking something like this:

combined with this:

running a tvs1320 or similar blower.

I'm not too familiar with the f20c and it's layout yet (I just picked up my first s2k a few weeks back) but this seems like a relatively clean and budget friendly option (as far as custom FI setups go). I don't know if anyone has tried it or if it has been discussed before, I was mainly hoping to get some ideas from folks that are more knowledgeable about these cars than I am.

 

Clearance to brake booster will almost certainly make this a non starter.

That said, I've been waiting 6+ years for someone to figure this out, and still hold out hope it will happen.

 

How about this:

First I've ever seen that. Wonder why they aren't selling it yet. But if they're going with fmic, I don't see the point in making it a cold side setup.

 

IMT is an excellent company and makes solid products. They did that S2000 setup as a one off. I know Merc purchased the manifold cast\design in that pic from another party. I am not a fan of his work as it always seems to be a copy of someone else's work just lower quality.

 

I had the same thought, I was thinking it might make sense to modify the manifold to remove the inter cooler ports. I really prefer not going with a an fmic for a really clean install, plus I'd like to keep it a bit stealth, and a fmic screams LOOK AT HOW FAST I AM!
I figure if it's only running 5-7psi I might be able to get away with no cooling setup after the s/c. Or maybe a water/meth injection setup if it's really necessary.

 

I figured that might be an issue, but i think it can be worked around, I'm not sure how but IMT managed to fit a cold side s/c, so there has to be enough room in there. I need to take some measurements but I'm hoping the way it works out the body of the s/c would clear the brake booster, and since a custom inlet would need to be made anyway that can be designed to clear the brake booster, although the inlet and the placement and routing of the intake presents it's own set of challenges.

 

Booster delete ?

 

Here's my thoughts on it. First, there's no point in making the custom intake manifold and all the other hassle for going coldside if you're still going to use a FMIC. It just seems utterly pointless. The benefit of coldside is having a very small compressed volume between the charger and intake valves, i.e. charger stacked on an air/water IC bolted straight to the intake.

Years ago, BR Performance, and subsequently Stage One Tuning who bought their designs, tried to do a coldside, and it never came about. My suspicion is it was a combination of prohibitive cost for a custom cast manifold, and prohibitive design due to not enough space between the head & brake booster (and all the other crap around it). I think their hotside solution with a barrel air/water IC was a great compromise, but unfortunately it just wasn't enough oompf for most of the guys that bought it, it seems. Clearly they had a hard time selling it with the 330 peak HP number it produced, and they closed up shop not too long after it went to market. They should have gone with a larger blower - TVS 1320 or ??? - at the very least.

What I want to know is, for those that would like a solution like this, would you be more willing to

(edit) apparently part of my post got cut off, had server issues when I was trying to post it

For those that would like a cold side positive displacement blower, would you be more willing to cut a hole in the hood for clearance, or go through the process of moving/deleting all of the braking and other components on that side that would be in the way? If we just accept adding a hood scoop (power bulge! ) to get the clearance we need, suddenly it becomes very easy to get everything attached where we want it - blower to air/water IC straight into the engine. I'd be more willing to go this route if it were me (but I'll stick with my KW v2 kit for now!), but ultimately I think it makes the most sense to make a hotside with a more agressive blower - something that can get us beyond 400whp at around the $6k mark.

LIke this, but slightly less ridiculous:

 

They hadn't have all the 3d scan software and rapid prototype/3d printing we have now that should bring r&d costs and time down.
