Hello again guys. I'm looking into what it will take to do a whipple swap. We're going to need two adapters, one to attach the whipple to the intake manifold, and one to attach the throttle body to the inlet of the whipple. Does anyone on here know who can make these? Vendors? Here is a picture of a kit designed for the W-bodies (Grand Prix's,etc.):





Thanks in advance for anyone who can help.

 

That thing is a beast

 

would be an awsome mod... but a verty costly... ur going to have to change alot in ur engine bay to have one of these bad boys...

 

You should hear it!!

 

I'm not so sure. From what I can tell, fitment shouldn't be that big of an issue. The whipple 100ax doesn't appear to be that much bigger than our M62's. The whipple in the above picture is a whipple 140ax which is bigger. Other than the two adapter plates and some minor stuff, I don't think it would be that bad. If we can get a vendor to put a kit together for us, it might not be as expensive as you'd think either. From what I've read, this moves enough air to make 280-300whp on a stock Cobalt SS/SC!(Assuming proper fuel,tuning,etc.). Plus there will be alot less parasitic loss, and alot less heat created. The 03-04 cobras see huge gains from these.

 

how much does one of those run?

 

let me talk to don and some people at nextgear www.nextgearinc.com im sure we can get something worked out for you

 

Wow!!!!

 

Great! Thanks! JCswoosher2, the most expensive part, just the whipple, is like $1500.00. I'm hoping to have a complete kit for ~$2K. It is an expensive mod, probably the same if not cheaper than going turbo though. The power gains, lower temps, and all of the other benefits make it worth it though.

 

You should pm Cobalt_Supercharged, hes been calling and finding out specs and was thinking about fabricating his own adaptor.

 

keep in mind that you will then have an m62 lying around, that is probably worth a nice chunk of change.

 

Dude it's an M62, who are you gonna sell it to? A Celica owner?

 

what does this thing do?

 

It's an all-around BETTER blower. Creates less heat, moves more air. Kind of like this: I have to run a 2.5" pulley to make 19.5 lbs of boost. With this whipple, it would probably only take a 3.25"(maybe bigger) pulley to make the same 19.5+lbs of boost. By not running such a small pulley, I free up alot of lost horsepower due to parasitic loss (it takes alot of horsepower from the engine to turn the blower that fast with a 2.5" pulley). With alot cooler outlet temps, we'll be able to run more timing. This whipple will move alot more air than the M62 will, even if the M62 was ported.

 

Thanks for the info.

 

Yeah max boost of like 32 or 35 psi!!!

 

A 2.4 SS A 2.4 SS (or G5 GT) person could pick this up for a few hundred bucks, and probably fabricate a complete supercharger kit for their 2.4 relatively cheap. The Grand prix people did this, and now there is actually a kit for the N/A 3.8's for ~$1,000 that uses the M90 off of the GTP's. A guy with an N/A 3.8 can buy this kit and almost run 13's. Heck, even the 2.2 guys could make a kit for cheap buying our used blowers. Keep that in mind. As for me, my car is on a smartbuy, so I have to keep my stock blower.

 

Is there any throttle bodies that would bolt up directly to the whipple ? Perhaps a 97-04 vette or 04 GTO drive by wire TB . I think their 75 mm , the LS2 TB's at 90mm would be a lil overkill . Im not sure how restrictive our throttle body is , but with a supercharger like that , it seems as if our stocker TB would become the bottle neck .

 

All it takes is for the first one to be made, which will be very expensive, but if we get enough serious people to put down money, we can make it happen.

 

I"m down.... I"m workin with someone for an m90 swap, but this would be much better

 

I would need facts not "would probably". It maybe true but you could be setting up for a dissappointment. shouldnt be that hard to see specs from both.

I would want to know the following

what is the max CFM of both?
What is the throttle body bore done for each when bench flow testing?
What is the max RPM for both blowers?

that fact is I know what the Stock blower can do. how is it that the Whipple is better as you say? Are there any disadvantages? Disadvantage would be that it may not have a by-pass valve so the car is under boost 100% of the time (gas mileage will get real bad).

I have not researched the Whipple at all so help me out and dont be critical or flame me. thanks

 

you would have to change a lot of internals!! Not only would the swap (s/c) be $$$$ but, preping our motor would be just as much, if not more. That would be a lot of boost though!!

 

that doesnt mean you have to run 32 to 35 pounds just that it is capable of producing those levels with now harm to the blower itself.

 

I have a friend that works for a fabrication company. They specialize in stuff just like that. The company is in Mesa Az. Lemme know if you want me to give him a call about it.

 

I'm not saying you have to run 30+ psi.......but who settles with the bare minimum? If I had a blower that was capable of producing 30+PSI I would do what I had to to get that boost!! That's all I ment by that.


If you had a blower that was capable of 30+ would you keep the levels at <20psi? I know I wouldn't.
