Default A supercharger build with actual power(Not Mine)

I was looking thru youtube and found this awesome awesome supercharge build which is the way I thought it would look if I ever did a sc build... here is the guy post http://www.youtube.com/user/white25sc check out the video sounds absolutely amazing he is pushing out like 25 psi and the belt is slipping at that, so there making like a 9 groove belt so hopefully it wont slip

It is a sweet motor. This motor is referenced in Skidd's SC thread as well.

And there is NO more information about it...... that vid is 3 years old almost.... Would be super cool if it actually went into a car with documentation.

Is it just me, or is that <dyno graph> very reminiscent of a turbo application? I'm surprised the torque is climbing so steeply so late in the curve.

there are different types of superchargers that have different effects.

Fair enough... Which one builds torque hard to 3700 before leveling off?

I would expect a flatter curve from positive displacement and a more consistent incline from centrifugal. This one seems to duplicate a turbo as it reaches full boost and levels out.

I suppose if they started the dyno run at 3k RPM, this could be the case, but I have no idea why you'd start a positive displacement dyno that high?

I'm not trying to say it's a bad plot or that it's not from this engine. It's just surprising to me that it looks like it does, based on what I've seen and experienced.

Hey Snow, I assume you are referring to the HP curve. Because thetorque curve remains pretty flat through the whole RPM range. Therefore the HP curve will climb constantly and even smoothly. Because as you know, HP is a function of Torque and RPM. So, a constant torque # will cause an increasing HP # as RPMs go up.

P.S. I'm about 95% sure that's a TwinScrew supercharger. Mind you, as soon as I read 25psi, I was pretty sure I'd find a TwinScrew SC. The Centri and Roots blowers struggle to get to high boost #s, where a TwinScrew manages it a bit easier.

I'm definitely looking at the torque curve, and what I'm looking at is the curve climbing from 3k to 4k and (sorta) flattening out after that.

Throw another 5% in; it's definitely a twin-screw. (Allllmost halfway down <this page> - highly pics intensive!) I'm leaning toward it being an Autorotor (pre-Whipple), and not just from its appearance - a buddy of mine was going to parallel the FI part of this build, down to the Laminovas.

I checked out the sight and there almost done with it, http://xcceleration.com/ thats the site, go to bottom of page, they have amazing pictures, very detailed mods. I was looking at the curve and its just amazing , Hp isnt even a curve its just a mountain! Almost seems like if they upd the rpm higher they would stillget more power. but who knows reliability. cant wait to see it on 1/4 mile and times

It's awesome... but we don't get to see any of their built cars running.... I would like to see some. I want to see what their setups are like and how well it works. I'm always up to trying new things.

So how much cash did they blow upgrading an N/A block to handle all that? I couldnt find a lsit of parts for that build. I know the sC was built in house. They've been working on this for years now.
