So UPS dropped this off today

It came with pullies sized 80mm to 100mm in increments of 5mm. The 100mm pulley should make around 8-9PSI. It's still within the more efficient area of the S/C (around 10K RPM) so you'd see a fairly linear drop off in power. I would guess 8-9PSI on E85 it would make maybe 280-300whp. I think at 15PSI on E85 it could make very close to 400WHP depending on the dyno.

Really the supercharger could be run to 15-16K RPM and probably make 18-20PSI, but I wouldn't do that with a stock engine.

Awesome!

Man I want one...

Oh.. this is interesting..

In for some results.

This will be fun to watch unfold. That thing will look gorgeous under the hood.

I emailed the company that manufactured the manifold. They no longer have the tooling and have no plans for further production for the motor. Shit.

Yeah Ken told me I had a piece of motorsports history, there will only ever be 4 of these made. They have three more forsale although two come with motors. The TVS guts just bolt in through the back of the housing so if it broke Magnusson or whoever could fix it, it is not a complete one off.


Here is a dyno running at 12 psi on 98 octane. Also this is on a 9.5:1 motor. It made higher numbers when they went to 14psi, right around 350 but I lost the dyno they sent. They also played around with less boost and running the motor to 8400 rpm. This is whp, the dyno they used was in NC, this brand apparently popular with NASCAR folks.

Would go nice with my trd theme...

Such a shame to, the 1320 really matches this engine well. It could easily run on either a stock motor or a built motor.

Kind of baffling why there isn't a company that wants to make a eaton tvs kit for the twins

Do you know why?

I don't know exactly why but Robert, the son/driver has a ride in another series this year. I'm sure it's cheaper for them to (likely) partially pay for a ride in a car built by someone else than to build their own. They had many problems keeping the FR-S running last year and I'm not surprised they didn't want to go through the growing pains and cost of continuing to sort everything out.

Designing and building the manifolds isn't cheap especially on our cars because of the twin heads. I've seen pictures out there of a billet manifold CNC'd by IAG which could really be adapted to any supercharger, I'm sure that's not cheap either though. This S/C is pretty big too, building it where you can keep stuff like the A/C might be difficult.

I'm not sure the TVS is the _best_ supercharger really. I am still more of a fan of the twin-screw stuff like the Whipple and Sprintex to be honest. But I really like the packaging of this with the twin air/water ICs. I had my eye on the Sprintex 335 setup but I'm not a fan of their Laminova I/C solution, it never seemed to work well even with the 210 sized supercharger.
