Its all good. I would be interested in the whole kit but I also want to see what a stock motor tuned can do. And how a stick motor sounds with the supercharger on it, if it makes that famous whine that they are known for. And if it can be reliable. All that stuff will play a huge factor in me getting the kit.

Yes, Si impeller and it was just over 12psi. If the serp belt would have held the power I would have seen over 14 psi and over 550whp.

I just unpacked the kit to get ready to install it on that car here and NOW I see what you are talking out. L.O.L. what a piece. Definitely will be putting some thought into possible ways to avoid using that particular component.

It's a good thing you and Topz are putting thought into it.. It seems clear that Stillen didn't devote much.

Having been in the industry a long time I can tell you that almost every forced induction kit I have ever installed was more of a "Starter Kit" than advertised. Having somewhat recently made the executive decision to not sell our CJM turbo system parts in a "complete kit", it is easy for me to relate with why it is like this.

There is really no end to it. You can just keep going forever and ever. There has to be a point where a product designer says ENOUGH and hits the release button. Each manufacturer has to decide where they want to draw that line. Sometimes you are better off getting less as the consumer, because you can use that leftover money to customize to your own preference.

When I first got started in the industry around year 2000, back then MOST F.I. kits would without a doubt blow your engine in short time without lots of improvement, especially in the fuel and tuning department. They just focused on getting you the hard parts that you need along with the BARE MINIMUM to get the car to drive down the street.

You also have my A2A kit in your hands that is going on that car right? You ditch the suffocation boot and use the direct fit filter I include in the kit.

Yup. I didnt realize you also included parts for the intake.. I figured it was just the intercooler kit.

Yup. Remember to look in the filter box for the reducing collar and the rest of the Tial parts should be in there too.

My new build is basically done just need to get the motor broken in but Im shooting for 7-750 at 20-21 psi.

Dang. I'm thinking you will need a v2 for that amount of psi.

How fast is that blower going to have to spin for that?

I think I will be able to get to 18-19 easily (because it has been done down in FL by Titan Motorsports) but getting the next few psi could be hard but I think it is possible.

I think around 68000. I had my supercharger rebuilt by 928 motorsports and they say I am good at that RPM.

This should be very interesting. Can you please start a new thread for this?

For that kind of RPM, yeah they can replace the bearings with some hybrid ceramics, but how about the impeller wheel, shouldn't that also need to be machined for much better balance? The limit imposed on these units takes into account both of those aspects.

I'm running the '9 psi' pulley and at 7500 engine RPM the impeller is spinning at just a hair over 56000. Do you know the diameter of your input pulley?

Their impeller is balanced to within .006g/inch at 60,000 RPM. So it will obviously be spinning faster but I don't think it will be enough to cause concern. Im going to start with a new combination and go from there. The 9 psi pulley, 2.85" supercharger pulley, and 3.47" jackshaft pulley. We might be bumping my redline up a little as well.

You guys w/ superchargers...what kinda quarter miles are you running?

I ran an 11.6 at 124 on my old setup. Should be much faster now.

What is the diameter of the 9 psi (or lb pulley as it is otherwise referred to) pulley?

It seems that there have been 2 different sizes going around. Mine is the 2.75" I believe you measure down inside the grooves where the belt lays.

Thank you for that. :tiphat:

Thank you for that. :tiphat:
