Thread: Thoughts opinions on supercharger VE setup.

hmmm....

I am interested as to how intake charge temps would compare to a t28 on 10-7psi.

This would be very important as to how much the sc14 can run on a stock ve setup.

The Snail: All of the sc14's I have seen have mounting holes parallel to the pulley. That has mounting holes perpendicular to the pulley?

The sc14 will safely go up to 12psi respectively. Of coarse after that the impellers cook themselves....perfect for a stock ve?

the question is can it provide that level of boost to 8000rpm+, and how badly is the intake charge heated?

A mate ran a sc14 on a ca18det. 8.5:1 compression
Did all right ran 10psi made 202whp and a fair bit of torque. The supercharger used to get pretty hot though
He did say if he was to do it again he would use a ca18de bottom end, and another mate has in fact done exactly that and it does appear to go much better but he's never had on the dyno for a tune/power run. The motor easily had more in it but the supercharger was starting to get out of its effeciency range. So the limiting factor was the definitely the sc14 supercharger. I reckon the supercharger for the VE would be the twin screw blower off the mercedes 3.2 v6 kompressor. instant boost from practically idle to redline! That blower would be the nuts and could give all the boost a ve could ever want. Though I suspect it would be a tight fit in a fwd engine bay though.

another question is if the high overlap of the 16/20/n1 cams will hurt performance like they seem to in a turbo situation?
i guess there will be no reversion issues, but maybe blowing through the combustion chamber?

thats what the tuner had told my mate about big cams and superchargers. if the overlap is large it just blows air through the combustion chamber. He still said you'll make more power with lairy cams though.

I think the point of this would be to keep it cheap and have it work reliably. Definitely the heat would be the largest concern here, perhaps with an efficient intercooler setup this thing can be safely run at 7-9psi on the stock ve with stock cams. I guess someone needs to just try it out and see what happens.

In an ideal world we wouldn't even be using this sc and one like the OP posted would be much more efficient. But this damn sc14 is so cheap, a sealed unit, and it has that awesome clutch property to it. I feel like a nice cheap setup would be great, provided the ve could handle the hot air.

The sc14 would be in its most effecient range at 7-9psi. They ran 7psi IIRC on the 2litre six they come off. They would be alright upto 10 psi at a push. but after that you'd just be pumping heat into the motor.
For a cheap setup it would be a really good option

I don't know if the roots style would compliment the VE much, but meh. A centrifugal charger would work the best, providing a nice powerband that keeps going. IF you could rev it high enough it would make really good power for very low boost levels.

Big cams can have the effect of pushing air straight through the engine, but on a turbocharged engine this can actually help spool the turbo. It will have some other issues though that need to be tuned.

Get the TRD charger from the TC and use that, or get any procharger. F1A anyone? lol, that would be rediculous!

Damn it sucks that this doesn't peak alot of vvl owners intrest. I am extremely interested in this, and would love to sc my NX. The thing would just be a monster, having great low-mid range power and still make even more power up top! I don't have PS or AC in the car anymore, and the battery has been relocated to the trunk, so i have a great deal of room in the engine bay now.
