Small world

Buddy of mine is a tuner at that company, and races a s2000. Go figure, right?

Wish I could buy just the heat exchanger, it's actually quad-pass which isn't something you see in off the shelf applications, not to mention it bolts right up to the car. Maybe one of the dealers can get ahold of just one of them.

Based on our discussion, the supercharger is being pushed to approximately 60% capacity. The stock engine will not be able to handle the torque of pushing the supercharger to 100% capacity (~15psi).

The kit is designed so that with an off-the-shelf setup, it has an OE level of reliability.

CSG will be one of the first, Cosworth dealers selling this system. The data we've seen is confidence inspiring, particularly given the transparent nature in which they're willing to answer all of our questions and concerns, unlike some other FI Manufacturers.

As of now, the only cutting necessary for this kit is the AC condenser belt cover, and possibly a small trimming of the radiator air guide to let the heat exchanger hoses through.

The kit retains the MAF sensor (unlike a previously popular supercharger).


Please ask any questions you have, and I will answer to the best of my ability.

Any chance the Cosworth or the "largE company" offering will be CARB approved? I'm guessing not likely the former, more likely the latter? I'm planning to purchase some sort of CARB legal FI in the near future so I'm very interested.

Thanks!

What's your opinions towards this kit on reliability and heat management for track use, not just spirited driving. I know people have reported sprintex kit as an example suffers greatly over a 15 min track session.

I'm guessing anyway.

I'm really glad to see more PD offerings coming to market, especially ones that hopefully wont be running well into the inefficient part of the compressors operating range.

I traded some emails with a couple Cosworth guys and I'm not sure I was talking to the right people. They were claiming it was larger than a TVS1320. I'm 99% sure it's a TVS900 since it has a 22K RPM max speed, looks identical to one and has an Eaton bypass valve. They said they would get back to me with the exact displacement tomorrow.

The key to spinning them that high is the intercooler/heat exchanger and it looks like Cosworth has a done a good job of that. I'm guessing the setup may be produced by Magnuson for them but that's just a guess. They did a lot of the legwork with the TRD supercharger and the setup is identical.

That is TBD, but largely determined by how efficient the heat exchanger setup is. The exchanger itself, IIRC, was a 2 pass unit (might be a 4) that was approximately 55-60% of the width of the radiator. The impact beam on the car was replaced with a beat rush bar to give the entire heat exchanger airflow. With a stock impact beam, a substantial portion would be covered.

I'll wait until I get to actually test one to pass judgement on the performance; everything at this moment is either hearsay or based on what I saw in person on the car.

Both are pursuing CARB. Whether they will follow through or not is a different story, but based on the reputation of the companies, I'd give Cosworth a pretty good chance, and the other company will not release a non-CARB product.

Cosworth should be submitting the initial CARB application in the near future, after a CARB tune is developed.

So your Big E buddy who has a S2000 don't want a PD blower on it ? There a lot of talking about it on s2ki, they should come in.

Not even on E85?
I agree with the other comments though, that other company as well as the parent company makes some dubiously stupid decisions.

Surely Cosworth did plenty of track testing as well as work on the engine dyno to be able to confirm this kit doesn't suffer from heat soak....

Its a 4 pass heat exchanger

IM just gonna let the ricer in me talk right now..


If nothing else, it makes for one hell of an Ooooo ahhhhhh when you open the hood.

So yeah it's an Eaton TVS900 as confirmed by the Cosworth guys. I'd be very very surprised if Magnuson didn't produce the kits for them, they had a joint kit in the past with the Cosworth NC Miata MP62 kit.

As far as displacement it's actually slightly smaller than the S5-210 Sprintex used on the Innovate kit. Roots blowers like this generally aren't as efficient as a twin-screw supercharger but they are including a decent IC setup which negates that. I would expect similar results on the street as with the Sprintex kit. It can spin to 22K RPM vs. 15K RPM max for the Sprintex S5-210 so ultimately as long as it's being cooled well it can make more power.

BTW the other company starting with E uses the same TVS superchargers in their systems, so I wouldn't be surprised if it's the same 900 model...

This has surfaced from a UK vendor on the kit:
