So a new company popped up producing cobalt and redline parts called Tag Racecraft
They are currently working on a kit that would allow the LSJ to run a Whipple charger and the benefits are less parasitic loss and half the heat at equal boost levels the thread is
Here you can read all about it in that thread as far as the technical stuff, now as far as I can see there shouldnt be any reason why this wouldnt work with the GM supercharger kit for the L61 ecos since the whipple is replacing the M62 which is the same charger of course on the J kits
With a whipple this really opens up the power that can be run, I believe up to 25 psi on this charger, which of course you would need a built motor to handle

It would be great to see whipple in the eco world.

2004 Cavalier. Razzi. (Sold)
1998 Corvette. Some mods.
1992 Typhoon. Lots of mods.
1994 Civic VX 44MPG
Whipple + Standalone could be sexy.
Me being relatively happy with my s/c = not sexy.
Somebody will do it.
Probably the only thing needed off the GM supercharger kit would be the intake manifold itself that is setup for the blower, the new belt and belt tensioner,possibly some cooling hoses, fueling would of course need some type of management, dont know how well hp tuners will work above 15psi

Lucky bastards

fortune cookie say:
better a delay than a disaster.
Um ... Tag Racecraft is far from a new company. Very capable guys there, local to me. I'm actually considering taking my car there for its dyno session - I hear only great things about them with Cobalts.

Slowly but surely may some day win this race...
Well yes , I should have stated new to gm stuff, most havent heard of them if they arent from Canada

Only issue with the Whipple on the Cavalier is going to be space...The M62 is relatively short, depends on which Whipple the put into the mix for it overall height (ask anyone with the 02 hood how close it is....)
Good point they are using the lysholm 1200ax i believe, if somone could find the dimensions then compare to a M62 it would be pretty easy to tell

Going to be a tight fit. The SC's look to be the same size, but the Whipple is going to need an adapter plate of some sort, and to make it efficient will be needing a minimum of .75"
I was watching this with my Cavalier, but I have already found the SC upgrade for the big car, just need money now....
can't wait to see people try this out to see the difference with out m62..

K, s'cuse my ignorance here, but what's the big differences between a Whipple charger and a Roots charger? Or is Whipple just the "brand" name for their Roots style? They look very similar in design, how they work, etc...what's da diff?

Theres alot of info out there on the subject I'll try to summarize the main points. The whipple is kinda a nickname as roots is to the Helical-Roots Eaton blowers. Its a twin screw blower similar to the Kahne Bell you see on mustangs. Comparison wise its alot more similar to a roots blower in the way that it works than the Centrifugal chargers (Vortech, Paxton, Procharger). A roots charger actually becomes less efficient the more rpms and boost it makes and the parasitic loss is highest of all charger types. A clear advantage of the roots has always been that it creates more boost on lower end than what the centrifugal does. This is why my RSM charged eco would lose to a GM charged eco every time.
While a centrifugal makes better top end cfm than the roots or whipple its a trade off for what it loses or just doesnt make down low. The whipple makes half as much heat at the same level of boost as a roots charger while having less parasitic loss. Thats the advantage of the whipple. The new product that eaton has come out with is trying to compete with the twin screw design is known as the TVS supercharger, its called a high helix charger, rather than a helical roots like the M45, M62, M90, M112, etc. To date the TVS isnt even on the market yet it just debuted at Sema a few months ago, its promising to say the least and Eaton is making the claim that it will change the industry and turbos will become antique, that of course is a big claim to make. The TVS creates more boost in a smaller package while doing this at lower RPM which means less heat and better durability. The TVS in time may become the #1 choice for supercharging but at this time the twin screw design is the best, which is the whipple.
Another unique feature of the whipple is the sound, while its not as cool as a vortech, its like a roots whine on crack, theres some vids of some whipple charged mustangs on you tube and stuff like that, its pretty insane.

whipple is a a twin screw type supercharger.. a real compressor not just a air pump like the roots type. screw type S/c are generally more effeicent. make more power because they run alot cooler and allows higher "boost"
thats the benefits of a whipple charger, the actaul differences i don't remember but its in the design of the rotors inside
lol rodimus types faster than me
that looks a lot like the superchargers Jackson Racing uses....are these the ones they use?
holy @!#$ rodimus you weren't kidding about the sound...... INSANE

Jackson just came out with a Centrifugal Variant they call the Rotrex, which they claim has less heat and lag than the Vortech Style
In the past though Jackson used roots blowers for all thier kits

Here you go. Twin screw superchargers are far more efficient(producing much less heat and I believe less accessory belt drag) than Root's types and provides boost faster than centrifical chargers(both supercharged centrifical and turbochargers). They're pretty nice.
I've never heard of this "part throttle" before. Does it just bolt on?
my bad lol

be neat if thay made one "plug and play" like i take my rotors out of my blower and slap this in and reconnect my snout....
but i think im going to get a LSJ manafold.......

Ok so basically from what I can glean from the pictures on that site, is the rotors (screws) inside have more "lobes" if you will, and they're not as wide or fat as a Roots style.
Roddy, I was lookin at the differences between a twin-screw vs Roots, not between a Roots/twin-screw vs. centrifugal, but thank you.
