Okay plan is $1500, this is to fit a small blower, small intercooler, rising rate fuel reg.
I need to know what is a good size (cheap) blower that only runs a small amount of boost, I don't want to spend any more than about $500

Intercooler I'm allowing $300 max...
Fuel Reg roughly the same $250...
Blower around the $400-500 mark...

Piping is not an issue I have 2x 2.5m lengths of 3" steel and about a foot of silicon hose to suit.
Bends and brackets will cost me from nothing to very cheap...

Thats the basics but I'll get into depth later on......

OK here's the thing about supercharging.

There's no cheap solution.... short of stealing something. People have tried - and people will continue to try - to get the "magic" solution that is cheap and gives you good increases....

Anything that is from a small japanese car (i assume you might have a toyota blower in mind) will just not flow enough air.

It's easy to pressurise air.... when it's static. It's quite difficult to pressurise air when the engine is sucking in 500 cubic feet of air every minute.

This is not what you want to hear, i acknowledge that. But a powerdyne blower would be the smallest air pump that's worthwhile - in my humble opinion.

Some info here on an XF w/ V8 and two 1ggze toyota blowers:

Pay particular attention to the bold bit... remember this is with two blowers.



But yeah... in my opinion, there is NO cheap solution. If there was, every man and his dog would have a quick, cheap 5L!!!

Yeah I'm aware that there is no cheap solution, never bloody is but that is what I had in mind. So they just won't be able to flow enough air, fair enuff thats all I needed to know.
Also recommending the Powerdynes what would you reccomend from them? As I said before I'm only looking for a low boost application not wanting to go over around 6 pound. The intercooler is only there to try and stop the detonation process but also I live in a rather warm climate and was hoping this would also help keep things cool.
I suppose using a powerdyne would also mean not having to plumb in oil feed and return lines

Thanks Mart.....

Yeah that's probably the main selling point for the powerdyne IMO - no oil lines.

But also, because they're not having hot engine oil pumped through them... the air charge they produce is significantly cooler than a vortech.

The "stage 1" kit i had from CAPA saw about 7.5psi at the rev limiter, so taking it out to, say 5500rpm produced about 6psi (check out the graph in my gallery, i think one of them has boost plotted on it).

I got away with no intercooling and the climate doesnt get much warmer than Adelaide in a dry, hot summer. I had the CAPA water injection system, but even then - i rarely used that (if i'd been sitting in traffic and intended to put the foot down, i would enable the water inj, because the engine soaks in a lot of heat sitting in traffic).

Only thing i really dont like about the centrifugal blowers like powerdynes and vortechs... is the big/expensive brackets needed to mount the things...

On another note what's the biggest blower that will fit in a V8 E series engine bay? Commo boys can fit V7 T trims with ease, or so they say.

The Commodore boys would be able to fit almost any size blower in there. The bracket they have for them leaves a lot of room. I still struggle to fit an S-Trim in my engine bay.

Umm I'm not up to spec on my vortech blower sizes and ratings. How much power is your S trim rated at? And what size is it (v1-v7)? All I've head about them is that V7's are supposedly the biggest and a T trim is the loudest vortech blower.

Any centrifugal supercharger costs a tidy penny even 2nd hand (I've looked at the option my self) and there are alot of hidden costs too.

A roots type would be easier but getting it to fit is another.

All the hidden $$$ all adds up and to find a unit for under 1.4 k is hard.

I've only got a V1 S-Trim, which the majority of people would have. They're basically the common ones.
The T-Trims are loud, but i reckon the S-Trim i have was basically as loud as another guy i know who has a T-Trim. Unless you get a V2 SQ, which are supposed to be quiet, they're all reasonably loud.
AFAIK the S-Trims are rated to about 700hp, and can supposedly make up to 20 PSI, but you'd need a Gilmour drive belt to run anything close to that i would reckon.
