Let me see, um, Critterman, Chemist, anyone else? How are they holding up. Glad you did it. What differences have you noticed since you got it installed. Fuel mileage? Butt Dyno.

Jackknife · « **Reply #1 on:** December 23, 2008, 09:23:35 PM »

Oh...there's no doubt...it's the best thing you can do to an NA Solstice.

What a transformation! Smooth, linear power...virtually from idle to wherever. Tractable, manageable, controllable...yet capable of truly impressive lay-down of power. It actually feels as if a small V8 is transplanted.

Fuel mileage (as if I care) never drops below 24-25 no matter how hard I play.

Randy and Dave performed a minor miracle with this set-up...and I, for one, am very appreciative.

Gotta love that supercharger wine too.

Great to see a section started on this! I can't wait to see pictures of them.

WORD! The Ion Red Line crowd likes to get the K&N CAI just to amplify the whine (I say "just" because we have a factory CAI so they don't give us any more power).

Edit: They also like to remove the silencer from the factory intake to get more whine.

Chemist · « **Reply #5 on:** December 23, 2008, 11:47:55 PM »

I'll echo Jackknife across the board. I love the power, mileage is acceptable when I put my foot in it, stock +/- 1 mpg when I drive "circumspectly"

.

The only thing I'd change (tension pulley design) will get changed when stage III comes out. I'll stay at stage II, but change to the new pulley design.

Here's a few pics of mine:

I can't wait until Dave and Randy start to research twin charging our cars. A whistle and a whine would sound amazing!

The whine is, indeed, intoxicating.

In fact, I read that after-market suppliers are getting requests from retailers to raise the level of the sound from the Eaton superchargers to a level above the OEM requirement.

The sound of pure power...music to my ears.

I though you had driven my car Joe, what can I say, I have had some issues, all when I was being an idiot. Thrown a belt or two (never under 7k) playing, ate some wiring, and could never hear the whine until I got rid of the magnaflow and went with the Solo SQR2.

:woohoo:It is a fun car to drive, it keeps up with the tuned GXP's, and turns heads everytime you let her whine

Wife wasn't too happy when I would hit

it as it liked to torque left, then right, then left in 1st and 2nd gear, very quickly and scary if you didn't know it was comming. backbrace and probeam took care of that, she squats and goes. Lot easier to take off without spinning the tires since that change as well. She will still light em up on demand, but the whole idea is to get the power to the ground.

Okay, I will shut my motormouth now didn't mean to write a book. Guess you could say I like it a lot, and waiting (in)patitently for Stage III

Dave@DDMworks · « **Reply #9 on:** December 24, 2008, 11:15:46 AM »

Yeah we have been waiting on the new pulleys to come in for the new supercharger set-up that we are doing. This is the first major revision to the kit since we released it and takes care of a couple things that I have wanted in the kit. The new kits will retain the stock autotensioner for the A/C and Alternator and then have a seperate 6 rib belt (instead of the factory 5 rib belt) that will be driving the supercharger with its own seperate autotensioner. This is a little rendering we did of the engine with the new supercharger set-up:

The rendering does not have the alternator or A/C Compressor in it, and is missing a few nuts and bolts, etc, but gives a general idea of what we did with the new set-up.

Chemist · « **Reply #10 on:** December 24, 2008, 11:59:21 AM »

Dave,

Speaking of the stock autotensioner, I'm hoping you've still got a few of those hanging about the shop to put back on those of us without them now, when we go to the new pulley system?

We may all have to dig through our boxes of parts, hadn't thought about that, good point

Dave kept mine when he did my install. Worst case is I'll order a new one.

Jackknife · « **Reply #13 on:** December 24, 2008, 06:47:27 PM »

I've got my old tensioner plus the original belt...wonder if that gets re-used also?

I would think so.

I'm dying ride in someone's blown LE5. The only supercharged 4cyl i've ever driven was a miniS but i'm figuring this is a lot more fun.

sol_man · « **Reply #16 on:** December 29, 2008, 08:55:23 AM »

Wow, thanks for posting the pics. I knew this setup was out there but it's awesome to see it. So great you can have the economy of a 4 banger with this much fun!!! I'd love the whine coming from the supercharger. Was at a store a few months ago and I heard that sound coming up behind. Nothing like that anywhere! Turned around and it was a blown late 60s Camaro. Brought a big smile to my face

Critterman · « **Reply #17 on:** December 29, 2008, 09:28:03 AM »

Idkfa,
You are in the tidewater area? You will have to come up to one of our runs, be glad to let you take it for a spin

Acadian · « **Reply #18 on:** January 02, 2009, 02:02:00 PM »

i just freakin love the thing....

whines as soon as you want more power + great on gas and almost silent when not sollicited.

best of both world.
amazing and usable torque curve, instant power at will

only bad part is that as it now goes quicker and faster you soon realize that a brake pad upgrade would be cool,(read wise)
that stiffening up the suspension would be cool,
that installing real tires instead of the stock rsa would be cool,(read wise )

but, if you do those upgrades, you might end up with a car that this quicker and one that outhandles a porsche boxster or cayman S that is 3 time the price.

Now that is way too cool.
the look on their face (in the rear view mirror of course )

priceless.

The Stage II DDM totally transforms the car. It provides awsome power while keeping the mileage and driveability close to stock. Instant passing power without downshifts.
Oh yeah, the sound is nice when the SC kicks in!
DDM is a first class company that stands behind their products.

spicy3480 · « **Reply #20 on:** February 07, 2009, 08:13:04 PM »

I can attest for the workmanship of DDM's products...I watched them install a SC at the LI mod meet and it fit like a glove. It's great quality, too. Not one part on it is cheap.

Go to this link and scroll down to see pictures of my DDM Stage II that I took while I was installing my kit. Mine has the new belt system on it.

Like everybody else, I absolutely love it. I think I have about 17k on mine. Don't regret it for a second. I don't think I can say anything else that hasn't already been said.

Spiky, you saw two go in that weekend .... well sort of. Mine came out and went back in after a nice shiney DDM header was bolted in

Lucy'sDaddy · « **Reply #24 on:** March 28, 2009, 09:58:13 PM »

I got some questions for you guys with blowers.

How much boost you guys are running? I'm running 10psi on my 3.8L S/C in my Monte Carlo Intimidator SS. 7.5 was stock. It's a stock M90, not the M112. I have no intercooler, but extras from ZZPerformance. You guys should be about 10-13psi? Anyone up to 16-17psi yet?

Are the intercoolers air to air or air to water like the Cobalts? Air to air like the GXP, right?

Has anyone put a GM cam kit in, or different rockers?
https://www.zzperformance.com/cobalt_ion/products1.php?id=862&catid=143

Are you porting the blowers and intakes? (this link shows the M90 ported)
https://www.zzperformance.com/grand_prix/products1.php?id=162&catid=106

Ported heads?
https://www.zzperformance.com/cobalt_ion/products1.php?id=920&catid=143

What size injectors are you using now? Anyone using 60#? 72# or 79#??? I'm using stock 34# and running out of steam.
http://www.zzperformance.com/cobalt_ion/products.php?id=174

What size S/C pulleys, stock 3.35, 3.1 or 3.0, or smaller? 2.8, 2.7, 2.6 or even the 2.5? I got a 3.4, with 3.8 stock, but again, no intercooler. Guys with I/C's on L67's are running 2.8's on their M90's, I drove one with a 3.0 on a ported M112.

Modular pulleys?
https://www.zzperformance.com/cobalt_ion/products1.php?id=446&catid=142

Are you using fuel pump voltage boosters?

Colder spark plugs? Copper? Iridiums? What?

How are you detecting and controlling knock retard?

Will the LS4 75mm TB bolt on as it does to the LSJ's, with minor modifications?
https://www.zzperformance.com/cobalt_ion/products1.php?id=999&catid=174

Is there plans for adding a turbo to the S/C, as ZZPerformance has done on their Cobalt? Every time I stop in there, they try to talk me into adding a turbo kit to my L67.
https://www.zzperformance.com/cobalt_ion/products1.php?id=871&catid=143
They have dyno'd 440whp on pump gas. These guys have the world record holder 3.8L FWD (900+bhp, 800whp), at 8.66 and 159 in the 1/4!
