Does anyone know a company that produces a supercharger for the s2000 utilizing a roots type blower. I would love to supercharge my S2K but the way i see it is the S2000 is already lacking in the torque department and a centrifigul supercharger such as comptechs seems to produce mainly top end horsepower. However most roots type superchargers seem to produce very linear powerbands with usual increases in hp 25-50% and torque 35-60%. Imagine that a S2000 with 330HP AND 230ft./lbs. oft torque That would be impressive! Watch out NSXs M's and Porsches its time for the s2000 to shine!!!

 

I wish....

 

I've wondered the same thing. What I have heard from members of this board is that if you gear a Roots-type supercharger to make good power in the engine midrange it over-revs at the high end. If you gear it to make good high-end power, there's not much boost in the midrange. So you wind up with a suboptimal system anyway.

Soon after the S2k was released Jackson Racing claimed that they were developing such a Roots-type system (based on a Sebring supercharger), but it never materialized.

 

I was told that the high reving nature of the engine makes engineering a positive displacement SC for this car much more expensive. The requirement to be efficient and reliable with a 1K to 9K range is apparently much more of a challenge than engine with a 6.5K cap. Not impossible, but not cost effective given the small market.

 

Tim at MG Racing was making one (Imported from a guy in Italy I think), But he has fallen on hard times and I don't think the project will ever materialize! Anyone know any updates?

 

cdelena, if what you say is true about it being not cost effective to produce a supercharger due to engine characteristics and limited demand then why did Jackson Racing develop one for the Integra Type R. This car revs to 9000 RPM's also and was produced in extremly low numbers for only two years. Anyway Magnusen SP? says on their website that they would lend their engineers to the development of a supercharger for resale. So all there needs to be is a demand and a small (or large) company to step up to the plate to see this materialize. Oh well, I guess im going the N/A route until one is developed. I see no use in spending $5000 on a comptech kit that adds 50ft./lbs. of torque at the most.

I would think as more and more S2000's hit the street and the potential market becomes larger, more FI applications will open up. So, if you are not in a hurry, I would suggest waiting it out and see what develops in the next year or two.

 

I'm with 9000Red, you figure its supply and demand eventually a kit will come out seeing there seems to be enough interest. So all we have to do is wait.

 

given that there are eaton blower applications for the b and h series motors, some of which rev to 8000rpm and produce nice torque gains all the way down to 1500rpm or so, i don't see how that extra 1000rpm is going to make a huge difference. the m62 would only be good for <10psi on an f20c, and i kind of doubt the m90 would fit. a lysholm piece would be excellent, but i don't know the specs on them.

i personally would NOT get a roots style blower for my s2000. having had one on my previous honda, i felt that while it added a ton of power it made the car somewhat "sluggish" and less responsive in certain situations. with the s2k, that would be a crime imho.
