I am going to try it this week with a 75mm pulley.

Using e85 and was seeing about 280 whp.
Great even torque line starting at just under 300rpm.

I have another frs with a gtx30r and until nearly 6600rpm
The 335 has more torque and power. The turbo of course leaves it behind in whp after that

The 210 can do about that on e85 @ 12psi IIRC (CR is probably the main factor there). Do you know what the post charger IATs were? I am assuming no matter how big the blower is you are still going to generate about the same amount of heat by compressing that air. Efficiencies and peek MAF might come into play at higher rpms and higher boost.

What do you think is possible with that blower and a built motor? How much boost do you think it can hold?

Do you have a plot you can share?

It's a big supercharger, I would expect it to be good to 20+ PSI on this motor. Biggest issue would be combating the additional heat generated at high boost. I haven't been real impressed by the integrated IC.

Iat were about 140 to 145. I have an aluminum intake manifold that I think needs a heat wrap.

Turbo car is still 12.5

Yes, I meant 3000 rpm.

Also I'm on an auto, so the torque converter starts slipping around 7100 I believe.

I think we should have left the cr stock.


The elevation change lowered boost more than expected. And the bigger heat exchanger and pump seem to have helped a lot with the iat, they were about 190 in Miami

So this isn't a Sprintex kit with the manifold, you are just adapting the 335 to a custom setup?

I think if you are running E85 I would keep the CR stock or maybe 11.5:1 until you get into big turbo numbers.

I think he meant to say intake. Not intake manifold. Granted the intake manifold is aluminum but it is still the same one from Sprintex that they provide with this kit. At least that's what it looks like from the pic in his build thread.

Thanks, I hadn't looked at his build thread.

Trying to order smaller pulley... Probably be 3 weeks minimum before I can get around to getting this done and back onto a dyno...

But remember he is at 5,000ft... So that might be a factor??? On a side note, does anyone know when the heck sprintex is releasing the 335? I'm getting anxious...

Why do you think that? Isn't it a locking converter? Why would it start to slip?

I got my 335 upgrade

Nice. I'm hoping they send some units over to the states some time soon. Sprintex USA still doesn't have an ETA on them.

Anyone try just buying the 335 blower from them? Or an authorized dealer selling the 335 for Minis? Use the 210 manifold and build the rest?

I called and asked. The guy I spoke with said the intake casting that bolts to the back of the blower is different. I could try to have something made but don't know how feasible it would be.

I've never seen a 210 but i the reason they decided to try the 335 is it fit.
