Whipple talked about making one for the LS1 a while back, is this it?

Now that's pretty cool! <img src="gr_images/icons/cool.gif" border="0">

It does look like a Whipple.

just me

pretty damn cool! That would give the ls1 one heck of a low end punch.Slick drive setup also.
I don't think it's a whipple though.
I think it's a Eaton/Magnuson blower.
sure looks like this unit to me- http://www.magnuson-products.com/mp1...generation.htm

LPE had a display at PRI that I missed...

Had two LS1s with (I heard) Lightning AM10 superchargers that are reverse mounted, are those pics from that?

well that would make sense then as the lightning uses an Eaton blower.

Ok, I found it in LPEs catalog and it is a Magnacharger. I sent them an e-mail to get the details.

What would need to be done to make it work on a f-body?

cut a hole in the hood...

Awesome! Maybe it'll fit under a WS6 hood? I remember a long post on LS1.com way back when where somebody with some connections in the industry trying to get one of these made, but I believe a whipple couldn't be made because it was making too much compression or somthing like that. I'd really like to have a roots-type blower.

roots style = good luck fitting some form of intercooler on the car..... although it looks very very nice.

Those look like pictures from SEMA, that iss where I saw them and talked to them about selling them. The problem is they are made for 5PSI MAX, and I know that is not enough power for the cost. <img src="graemlins/gr_devil.gif" border="0" alt="[devil]" />

It really doesn't appear to be that tall. It sits a little forward also, probably will miss the windshield base. I can't tell exactly, but that throttle body appears to be in the more or less stock location. It might work on an F-body. Only 5 lbs of boost is a bit of a let down though. <img src="gr_eek2.gif" border="0">
<img src="graemlins/gr_judge.gif" border="0" alt="[judgement]" /> Is that thing intercooled? <img src="graemlins/gr_judge.gif" border="0" alt="[judgement]" />

Don't those Roots/screw-type blowers move a lot more *volume* of air than the centrifugal blowers? This thing probably makes a full 5si at idle and would give you a lot of low-end torque.

Dave

keep in mind that the centrifugal blowers are VERY peaky (boost proportional to RPM squared); ATI fr'instance; makes essentially no boost below 3000 RPM and then whammo! <img src="graemlins/gr_bs.gif" border="0" alt="[bullshit]" />
The Roots is more linear so you have the boost Right Now - fow me, mostly street driven application, this makes a lot more sense. For all-out drag racing, well, the centrifugal+intercooler looks good, but notice they all run Roots blowers on the really fast cars! <img src="graemlins/gr_judge.gif" border="0" alt="[judgement]" />

next question: how much and how soon?
gotta be expensive with that alloy intake manifold and Rube Goldberg pulley kludge

hey, if you need intercooling, a little nitrous goes a long way! <img src="graemlins/gr_devil.gif" border="0" alt="[devil]" />

Okay, I may be as thick as a whale omelet, but if you have to alter the hood anyway, how about mounting the damned thing so that the pulley is in the front??

I dont see an intercooler in that picture so with a stock PCM and 10:1 motor, and and 91-93 octane your boost level cannot really go any high then 5 PSI, some thing are true, yes you will have instant boost, when you give it gas, this is one of the reason why GTP are so quick when lightly modded. also if you were to add an intercoolering you would be putting a peice of metal with a heat exchanger between the intake and the blower, thus rasing it up high, maybe maybe there is something down there Im not sure, but that would be awesome. the root style blower outputs an extreme amount of heat on the intake charge also, i think for some people this is gonna be a awesome solution. also about centrifugal blowers prucing boost below 3k rpms, i wouldnt want that anyway, that means you cant run as much boost, and when your racing your rpms are usually between 4-7k right? a turbo or a roots style blowers would be a awesome street setup, IMO

Rock

Roots types are very cool, but there is one disadvantage due to the way they produce boost. If you have a centrifugal type, and you don't want to boost, you don't have to. This saves gas and would undoubtedly prolong the life of your motor. Whereas the roots usualy have a violent spike of boost that is hard on gaskets and parts and happens right off idle.

Just a concern for us with daily driver blown F cars.

speaking of intercoolers, last truck'n nat's i saw a jeep wrangler in a company booth with a kenne bell roots unit, after talking to the representative about how you can't go above 5 psi on that unit because of the lack of intercooling, i was surprised to know it was intercooled!!! the intercooler was a plate 1.5-2 inches high and was very efficient . so efficient that that jeep had stock internals and was pushing 8~9 lbs of boost!
now whaere they got it from , and if it is applicable here , i have no idea...

if you have access to a machinist shop, you can make them, you need a heat exchange built in to it with two fitting a radiotor and a water pump to move the water, yes they are made, and they will also make hood clearance more of an issue with, after market hoods.

The dialog seems to go: if somebody decided to actually produce this bad boy, then you need an intercooler. Not exactly true.

You can do the same thing (or get the same effect) with Water Injection. This technology dates back to WWII fighter planes. And is used a lot, by the Supercharged Grand Prix community. Many other Turbo cars employe them, as well.

Check out this link:
http://www.aquamist.co.uk/

I know a good source in the US who has installed HUNDREDS of these products, I have one on my GTP and I am producing 14.5 pounds of boost vs. stock boost of 8-9 pounds. With NO side effects.

If you are having problems with KR (knock retard) after big engine mods. this could probably be a solution for you. Spray (okay fine mist) some water into the incoming air, mine is laced with methol alcohol! Reduce temps and the KR problem, you don't need an intercooler. No problem finding space to mount water injection system, you won't have to cut up your engine compartment to cool the incoming air.

Email me if you have questions.

YEP , water/alky is the soloution.
I run 10psi boost on 10-1 stock pistons with no intercooler (vortech).
I use a custom built water/alky system and this alone drops charge temps by about 90 degrees and then the water/alky is a extremely potent anti detonation mix.
I use 100psi and a good mini atomizing nozzle to fog the mix into the intake.
This would be even easier to engineer on the roots blower as the rotors will atomize the mix very well.
