Eaton SC M20 HP/TQ RESULTS and decision?!?

Twin charging is way too inefficient. Trust me I used to drive a 06 cobalt ss and was heavily involved in the forums and modifying my own. A lot of guys over there started off twin charging ZZPerformance made a kit for it. The M62 is known as a heaton blower and so unless you are running a water cooled turbo and a water to air heat exchanger your iats are going to be hard to control. ZZP no longer offers the twin charge kit because they have found it more efficient to run a single turbo and remove the supercharger completely. I think as far as uniqueness goes twincharge wins but efficiency wise single turbo is the way to go.

Inefficient..lol... sorry your wrong. Have you seen the torque line of a twincharged car thats properly setup? have you seen the power of the lancia delta S4? Just so you know I was a moderator and writer for Cobaltss.net and I know all about the cobalt ss I tuned them and ZZP was my sponsor I was one of the first to own one in Ontario in 2005. My temps with my setup are 8-10 degree over ambient temp right now at 17 PSI total cars power is unreal to anything I drove before and I drove 11's Eagle talon TSI AWD.

ZZP no longer makes the kit as it cost too much money to build and it was complicated to maintain client service level support. Twincharging is not for everybody and is complicated but the reward is not only unique but u take the best of both worlds and have a powerful street car that doesnt need to spool to 4000RPM to make any kind of power.

I'm considering a very similar setup with an M90 from a Pontiac 3.8 and a GT42. Just as far as the set up is concerned, does it go turbo->intercooler->BOV->throttle->SC->recirc.? I'm having trouble understanding the order... And you'd have to convert to an MS system and not use an AFM or a MAF, correct?

The M90 from the pontiac wont fit its too big.... the m90 from the thunderbird will fit. MS all the way!! yes

I'm sorry but being too stupid to tune a WAR chip doesn't make it junk.

That being said I've enjoyed both WHODWHO's megasquirt setup and the WAR chip.

The war chip is very useful, but not perfect. The big issue is that you don't actually get full access to all tables. It's kind of a downer, although understandable.

Yeap I just read more on it EFI analytics looks pretty awesome. The best software I ever used to tune was HPtuners this looks as good if not better.

[FLG]

Yep efi analytics (tuner studio) has some cool stuff out

Really! wow!! Man, I got lots to read up to catch up with all the new stuff MS does now! I was thinking about getting an android phone.

Get the blue tooth adapter and download there shadow dash and you can even do stuff with an Android tablet or phone

the War chip served me very well for my 12 PSI setup... but I will absolutly need the more avdanced and precise features of MS to go beyond this setup I have now.

Plus I love the fact you can datalog with MS :) cant wait to get my new setup in place.

you'll be amazed how much simpler megasquirt is than the war chip junk

My WARCHIP and MAF are sold.

I unlisted the services of WHODWHO to help me setup my new DIYPNP box :)

If everything is good then I should be able to start my TWINCHARGE project this winter.

HX40 is really too big for only 400hp. HX35 is fine for that number.

Actually I would not mind a turbo that spools 4-5K as I already have serious torque from 1500-4800rpm at 12 PSI of SC boost. I think I HX40-HX45 would probably be more bang for the buck?

Twin charge and a pair of soft compound r-comps will take care of wheel spin. Stock tires are no match for my setup either.... R-comps on the other hand grip like crazy and instead of wheel spin she sits down.

Yes at the track am going to buy some slicks (I can get a pair for 50$ at the race track slightly used....just dont know what size and rim size I need)?

I'd personally love to see a twin charged m20. Do it!

Its looking more and more like this... but I need to sell my Miller stuff before and get MS2 and get familiar with it..

the Miller stuff is good until 30# injectors are maxed out around 12 PSI on a B25....but now I really need a more advanced EFI tuning hence MS2..
