2006ArrivalBlueSS: Excellent right up.

I think there is a lot of misinformation out there around superchargers and size.

 

Thanks, but I can't take credit for the write up - just a good find is all I guess

 

how much power are they making?

 

dig a little harder...
there are quite a few of us on tranny #2
mine let go at a certain track in my area. had to push the car out to the road then call roadside :\

when i met him, twincharged made 330whp that afternoon. this was about 3 weeks ago.

 

gravana i think was supposed to be making a twin charged setup for sema this year. i think they said something about it last year being good for 300whp.

 

i know the head gasket goes at 24psi (confirmed by blowing it a second time at the same boost levels)

 

you can break that with a blower swap... easily

 

i predict that the m90 kit will be as popular as the m112 kit for the grand prix that intense sells... hmmm how many people have that again??

 

Any hints of a screw type in the near future?

 

I love the idea of a different supercharger on the car...whether it is M90 or what not, but if the price of doing a M90 is going to cost as much as when they do M90 to M112, then the WHIPPLE looks very nice. The 1600AX was quoted at $1500. and there are lots of benefits to it. To get the same cfm as the M62, it would require around a 3.8" pulley or 3.6" (larger than stock M62)...The larger the pulley=less revolutions...less revolution=less heat which gives more dense air, etc etc which means with proper tuning and a 3.3" pulley on a whipple. forged pistons, a whole lot more tuning means one bad ass blown LSJ.

 

its a show car, it probably never gets driven enough to see boost anyway, so i really don't see the point.

Twincharging is the biggest waste of time and money on a fwd car. All it does is give you a really incredibly broad powerband that you can't even use half of anyway because you have no traction. A well matched turbo designed to put the power in the useable racing range (mid-high) will no doubt be easier to tune and a lot easier to drive. Lets not forget that torque spike is what kills rods, and torque spike is all you get with a twincharged setup.

Take off the M62, put on a GM racing or Hahn intake manifold, or build your own (4G63 intake manis have identical port spacing, saw off the flange and have a welder weld on the LSJ flange that you can get from GMPP). Then, when your turbo kit is complete, you can sell the whole supercharger setup to an ecotec cavalier owner, or anyone with a 2.2/2.4SS and recoup a significant portion of the cost of your turbo setup.

 

you sure thats a "gasket problem" and not a "head flex problem"?

 

look screw all this bigger blower bs i just say say we ditch tha roots an go centrifical then we dont have anything to complain bout yea yea yea i kno it would b alot off $$$$$ but wtf u would make more power

 

Quite possible the head may lift under high boost, thus requiring the need for a better head stud with a washer that will allowing for proper clamping and even securing of
the head.

A problem found in the SRT circles with the ARP studs as they don't provide aduqate clamping force and the head would lift under extreme boost levels, causing head gasket failures.

Fortunately for the SRT crowd a company called Darrell *** came to the rescue with a
better designed headstud kit that has been tested on a 1200hp drag SRT-4 driven by Mike Crawford. These very studs are in my SRT and so far we have hit them with 38psi from a GT35R Turbo.

The ARP's for the Ecotec 2.0 may be just fine, I will explore this potiential issue when
I rebuild my 2006 SS with better internals....

 

The build book doesn't mention any head studs other than the one listed from ARP or Bates. I'm assuming they use the same ones all the way to the 1400hp drag car. They run higher compression and 21 PSI on the Phase 5 Cobalts. I would think that it is the head gasket failing, assuming that Selfinfliction used the studs listed in the build book.

 

using the M90 would be a good upgrade from the M62. it will not give gains like the whipple does but it will increase power alot. at the same boost level the M90 will out perform. the good thing is that companys make pulleys for them and other parts that could help build performance.

 

It also sucks a lot more power in the process. A Whipple W75AX would produce 22 psi while consuming the same amount of power as the stock M62. While still giving a lower charge temp.
