Australia oi oi oi!

haha. yeah they are a good thing the sprint chargers.

can't wait to get mine going so close. once my dsn stuff arrives full steam ahead *happy*

This could be interesting.....

I haven't looked into the figures of the sprintex (that Paul will have done) but I guess that it's not very efficient, thus makes lots of heat and poor power. Just like an M45, but even worse.

The only advantage over the M45 is probably packaging.

Sydney, Australia!

They are one of the most efficient superchargers... volumetric efficiency is around 90-94%...

A straight swap with a M45 will give 20-30hp

Poor adiabatic efficiency at anything other than low boost and no intercooling.

Just been looking through the figures. And yes it's a bit crap. Sure it has some nice high efficiency figures, but they're all at 5psi. Anything decent like 15psi and you're looking at less than 50% efficient.

Would you run an SC in this setup anything other than 12PSI?

12PSI and some water should be safe

I run a supercharger and I don't care the TB is on the wrong side.

At 12psi you're looking at 60% efficient, with no IC that would be a hot charge and need some water.

The SC12 kit as a) It's cheaper and b) the carb is close enough to the charger not to suffer from carb icing. Downsides are that you have to get most/all of it from Australia and the chargers are not all that common. I was very impressed with the driveablity of Graham's car as a passenger.

I don't like the M45 as the carb is miles away from the engine (icing) and it's really inefficient for the application. Not aware of anything else on the market that is available in kit form (aside from the one in the original topic that is in the pipeline).

Compressor map? Unfortunately there isn't one readily available on the interweb.

My problem with the SC12 is that it is a simple two lobe roots blower.

1940s technology and inherently less efficient design than the Eaton or the Sprintex.

EDIT: Actually designed in 1860 *surprised*

and thats the reason I love it.... It looks the part on an old car.
The car went well considering the engine was built in 1969, and its only had a top end rebuild.

I'm now after twenty years of ownership (SC installed in 2007) it needs a gearbox rebuild, but then its always been tight and its only bad when changing down at speed.

Still love the car just feels like a big engine.

I know all the pros for turbo, and I dont disagree with them. I just went a different way as it was easier at the time and the cost was extremely low.. I did it for a tax rebate.. and about 1/2 the cost of a turbo setup. You cant now mind..

The car has then slowly received a number of upgrades over the years to improve the over all car, with a fast road going theme.

I did see a map somewhere but it was a long time ago.

oh and I'm just under 80bhp at the wheels. before all this stuff the car was measured at 24bhp at the wheels.

You'll get more power pr psi, you'll get better mpg, you can have a dump valve (which has be scientifically proven to get you more fanny). It's easier to run an intercooler, modern correctly sized turbos have lower boost thresholds and minimal lag.

Can you get mirage style manifolds for these newer style turbo thingies? Does anyone do a complete kit, with everything ready?
Intrested although I could never trust myself to not turn the boost up :)

Should I staple my ball bag to my legs just incase?

If we're getting into debates about what constitutes a good set up and what doesn't I will just throw my latest idea out there.

1380cc with k1200rs head, and an M45 blowing 12psi at 7500rpm, Via an intercooler.

My reasoning for wanting to use the charger is so that as revs increase so does boost, obviously suiting the higher flowing k1200 head with hotter cams. Basically an engine that rewards you for revving it is what I'm trying to achieve.

Initial calculations show this should deliver some decent numbers, but based mainly on estimated maps and flow figueres for the m45.
