Attention stockoau: 4l + PD pics!

[superroo]

I've just rerun those calculation for the M90 and come up around the 10psi too.

And i was just about to say the same, for a stock motor, 10psi is more than enough. And adding to that, 10psi from a PD blower will be a better 10psi from a turbo.

If people are going to go second hand M90's i would just be warned about the wear that they have. A worn roots blower will produce alot of heat which is not from a performance aspect or a detonation aspect either.

But for the price, if you could do the fabrication work yourself and the install as well, you could probably do it for under $3000, with a new blower. But that will have no engineering certificate or be road legal, so to speak. But since when did that stop us : :eclipsee_

I live in QLD, the boost friendly state :

With getting 20psi from a Wipple, I have no doubts it would produce this, but you would need $20k just to get started with costs of an engine, tranny, diff and so on. Would a car even be drivable with 20psi of boost at less then 2000rpm? Just because the blower can do it doesn't mean it has to.

I sooo wish you QLDers would stop rubbing this in! It hurts ok :(

True point and i accept that. To run that boost/power it is going to cost alot to get it reliable. I did a quick cost summary and i can spend $30k without touching the engine, just to get it ready for that amount of boost. No engine work, blower brought, or respray done.

As for driveability, that is the beauty of the whipple and the M90, they produce boost right from idle, they always make power. They are well suited to "doughy" engines, that lack power down low, such as a low compression motor, in need of boost

Another benefit of these kinds of blowers is that boost can be changed in about 5 minutes, simply by changing the blower pully. You can undrive them massivley and they won't complain. They will run 5psi, as easily as they will run 10psi or 15psi or more

Another interesting point with kev's ute, if he drives it sensible it uses less petrol than what it did from the factory. He puts this down to the blower and the fact that he doesn't have to lean on the car as hard to get it do what he wants. But stand on the throttle and watch the petrol guage drop.
The only driveability he has lost is grip. ====================:eclipsee_

Grip is what I was talking about, I can't see you having any running 20psi

Funny you bring that up, initially the were going to read “Queensland The Intellectually Superior State” but it was decided best to dumb it down so the rest of Australia could understand it

hahaha...

hrmm.. i might have to talk to my fabricator mate tomorrow night... ask him how hard it is to make up a manifold for one of these things... if he says he could try it... i might have to source an M90 and see how i go

Which is something along the lines of what I was going to say about the 160RWKW AU pictured at the top of the thread. Other members here have found the stock fuel system is good to between 160 and 170RWKW. That system is no doubt out almost to the fuel system's limit at 5psi, but the blower has headroom with a pulley change to go to double that. The owner has done the hard yards or big $$$'s to get to where it is now. If he wants to take it further a pulley, fuel pump and regulator, injectors and retune could gain him another 40-60RWKW for maybe $2K if he buys well and can fit the hardware himself... maybe 3K for a shop to do it all.

tho i have a question... what is the difference between these 2 eaton units...

one is labeled an M90.. the other as just a 90...

are they the same thing?.. if so.. why is one longer with extra stuff on it?.. (i know nothing about PD superchargers)

There are a couple of different ways to do it. The pictures show one way, with effectively a custom manifold. It can also be done with the blower mounted "remotely", ie on a bracket like the CAPA and Raptor units, boosting into a pipe which connects to the stock manifold. This bloke http://www.fordmods.com/forums/download.php?id=18609 and http://www.fordmods.com/forums/download.php?id=18608 has an AU engine in an NC Fairlane with a remote-mounted M90. It blows into a FMIC, returns out the passenger side and into a custom manifold... different again.

There's a bloke here in Newy who reckons he could fab up something for me if I gave him the car for 3 days. If he worked on it full-time for 3 days it'd be maybe $2K labour (GST included) plus materials????

Both are M90's. The snouts are different lengths to suit different mounting positions. AFAIK you can get different length snouts & change them over. CAPA have them & of course they are gold-plated. Don't know ATM where else to get them or what to ask for. Another gotcha is that the pulleys are pressed on with big tonnage presses. You can get replaceable pulley kits that let you change pulleys easily, these usually include hire of a pulley removal tool so you can get the stock pulley off & fit the kit.

hrmm.. ta...

i'll have to have a good chat with my mate tomorrow.. he knows a thing of 50 about boost.. heh.. he's built an 11 second sigma.. plus now an old school lancer but i think he's yet to run it.. which is all the motor etc from the sigma...

[sly]

Not the Sigma with the supercharged Commy V6?

[Eu-GenixX]

nah nah... he used a standard 2.6 astron II motor... bolted a turbo onto it.. upgraded pistons.. then melted them at 19psi.. so did a full strip and rebuild... beefed up everything.. using a GT35/40.. running around 26 psi ... making a touch under 400hp at the wheels...

[sly]

Noice. I have a '87 Courier fourbie which has an astron II... Mazda bought a batch to use while developing their 12V EFI 2.6... 8.2:1 compression... it'd be massively improved by the addition of 6 or so psi and I think the manifold from the Sigma Turbo would bolt on. Back in the day they used to decompress down to low-mid 7's and had massive lag. With advances in technology since then a low-blow turbo would be very nice on the stock compression, especially running LPG. I might do it if my plans for the Falcon keep getting frustrated.

It's something I could pull apart and take the time to play around with myself as I don't drive it that often. I don't have that luxury with the Falcon unfortunately, anything I put on it has to be fully-developed to bolt on and go in 2 days or less.

[Tradewind]

I saw an 88 extra Cab Courier 4x4 in traffic in Bris yesterday, was running the 2.6 EFI engine and one hella turbo, peeled rubber for the first three gears and the rubber was those 10R15s 4WD tyres. I was aghast at how quick this thing picked up speed, I think a 13 second quarter would have a real possibility.

[blackers10]

was it white??
ive seen that at harrys diner before
was pretty tidy in the engine bay!

theres also a few 4x4 hilux's with supra motors in them that peel big 4x4 tyres like they are 13" cheese cutters!
