3500 for 60 rwhp isnt bad... granted once different sizes pulleys are added the result might be higher (larger lower, smaller upper), also tuning could be a factor as well....

A supercharger will also "take a toll" on the internals, especially the valvetrain. Nitrous has been applied a few times that I know of on the J-Series and it's performed great.
The 3rd Gen TL supercharger will cost more than $3,500. The 2nd Gen kit could be had at that price if you knew who to talk to. Most likely there will not be a higher boost upgrade available on this kit. Compression is already pretty high and there isn't much in the way of tuning available on these ECUs. It's possible and it would be nice, but I wouldn't count on it.
And don't expect to gain 60 horsepower at the REAR wheels
TL is FWD, but I'm sure you knew that.

When development takes this long I certainly can. You have to pay for R&D somehow and Comptech reportedly brought in engineers from other companies, including Honda, to try and figure out how to get around this ECU. That all adds up. Plus all the elbows, the shaft, etc is all designed by Comptech but an outside shop casts them.

It doesn't whistle but it rattles at little. You can hear it spinning from outside the car but when you're inside you can't hear it until you step on the gas and it starts to whine

I was cruisin around myrtle beach, SC earlier this summer and came up on a nicely done silver CL. I spotted a gauge pod and assumed it was a boost gauge. We got on it and i heard the whine from his engine bay. The sound i heard that night is inspiring me to get the comptech charger. It sounds awesome if you've never heard it.

mrsteve, thanks for the links! that really helps! What type of cars were those? Also, I noticed that on one of those links, the supercharger doesnt make that noise until 4K rpms. I thought superchargers were for lower RPM applications? I could be wrong as im no expert.

That's on a 2nd Gen CL-S. Same blower as the 3rd Gen TL. It will sound the same. And the blower makes the most noise in the upper RPMs. As it starts to spin it makes noise. The faster it spins the more whine so at the lower RPMs it isn't spining that fast yet.

My choice would be a turbo. Bypassed when not needed/wanted, adjusted up when needed/wanted.
From what i've seen, a turbo or twin turbo setup, cooled either with intercooler or NOS is the best way to go for pump gas motors. And, as i've said before, the right way to do it will run about $15k.

Not true at all! A supercharger does not constantly boost the motor! Only when the bypass valve has been opened will the supercharger push air through the intake manifold.
In fact I've analyzed quite a few data logs from boosted RSX-S's both turbo and supercharged and the turbocharged cars were under boost more often than the supercharged cars under normal driving conditions.
And i'd love to see where you'd find the place to put two turbos under the hood of a 3rd Gen TL

The SC is mine as soon as it comes out. I have the money to burn...so I will. I'll post Dyno results ASAP. C'mon fellas....5K? Ya'll can afford a $36,000 car right? Just pretend that you got the A-SPEC kit installed. My car off the lot with an A-SPEC kit installed by the dealer comes to around 41K with labor. So say you don't have the A-SPEC kit.... well, install the SC (whenever they decided to let us buy it) and you will be lookin at 41K installed. ya'll know you want it. So what if your car breaks... fix it!

One of you guys was wondering what the car sounds like at idle. This was taken in a parking garage so it's a little louder than it would be out in the open:

And here's a run from 1st through half of 4th.
http://photos.imageevent.com/mrsteve...51009_0002.AVI
Expect similar sounds and acceleration from the 3rd Gen TL

Twin turbos is doable, you just need to have good fabrication skills and somene who knows turbos.
In either case, the installation of a forced induction system on top of a oem motor that is already at 11:1 is at best, a short term solution.

No actually. Even at partial throttle acceleration you aren't boosting all the time. I've been driving a supercharged car for over a year now for about 20k miles and you only boost when you want to. 90% of the time the bypass is open. Only when the load is high enough will you be under boost not everytime you step on the gas.
And short term solution? There's easily over 300,000 miles on supercharged RSX-S's with minimal problems and no reoccuring problems on those below 9psi. Don't know what to tell you other than you're wrong.

It's all very interesting.

I've got a boost/vaccum gauge in the car and I can go an entire day of driving without boosting. The bypass valve isn't an on/off switch.
And the J-Series and K-Series have no problem with moderate boost levels. Boosting 7psi bumped my automatic CL-S from 227whp to 295whp.
The RSX's usually make around 300whp with 9psi.
Again, with no problems. Do you really think if it wasn't reliable that my dealership would sell it/install it?

There's something way wrong with your SC setup then. At 7psi your 227hp motor should be pumping out around 330hp !!
Every psi of boost equates to approx 6.8% increase, minus some parasitic drag and driveline loss.

Stop analyzing things just off formulas and what you've learned in the past. The fact is NO ONE has ever put down more wheel horsepower on the same set up than my first car did. No one on this forum. Normally they dyno around 270-280 with the same boost levels. Nothing was wrong with the setup or my car.

It's approx 6.7% per psi. Your 7psi claim on a 227 motor means your SC should be increasing your output by 6.7%*7= +46.9% more hp & torq = 0.469*227hp + 227hp = ~333.46hp
mrsteve, somewhere in your setup you're losing ~40hp, that's allot of loss. I think your 7psi reading is slightly high. Here's some FAQs from one of the sources above.
"If I buy a 5 psi kit, will it develop a full 5 psi boost under all conditions? Some will and some won't. Ours will. There's only one reason you buy a supercharger kit - for the boost. Here's how you test it. Floor the throttle from a dead stop and look at the boost gauge. If it reads 5 psi you should be happy (5 psi X 7% = 35% more HP and torque). You've got what you paid for. If the boost only reads 1-2 psi (2 X 7% = 14% more HP and torque) are you happy with that particular 5 psi kit?"
"How much HP and torque can I expect from a supercharger kit? This is answered in more detail elsewhere but typically 6-8% per psi boost depending on the engine. On some highly efficient engines such as the Mazda Miata 1.8, we've seen up to 10%!"

That formula can't be applied universally across the board. 5psi will increase horsepower a lot more on a J32 than it would on a Mitsubishi EVO. Doesn't make sense.
Trust me, about a dozen automatic CL's that are supercharged have dyno'd and I was the highest.

Umm, well, loss through the drivetrain should remain about contsant, boosted or not, so when applying the % increase in hp and torq from boost it applies directly to whp or flywheel, does not matter.
I'm not disputing that you have the best SC'd setup or not, I think your #'s are off, that's all, and others need to be aware of how this stuff is suppose to work and how it should be done right.
anyone?

Whatever you say pal. Sure my numbers are off.
You aren't comparing apples to apples here. If, based on your theory 7psi is 7psi is 7psi then why would a turbocharged J32 make so much more power at only 6psi than my car did at 7psi? The supercharger takes power to make power. You can't apply your 6.9% or whatever it was across the board for all types of forced induction on all cars.
Lets keep it at just superchargers. 5psi from an MP62 blower will not make the same amount of power as 5psi from a MP90 blower and surely not as much as a MP112 but it would from an MP45. The volume of air from each of those units is different, yet the pressure is the same. I believe you stumbled across some information but you are interpreting it incorrectly.

The Supercharger is Here
We are being told by production that they will begin shipping in November. We currently have over 20 on order, so the wait is slightly longer for new orders; if you would like to place an order, please call sales at 888-626-6783. Thanks for considering Comptech.

that would be real nice. I was going at it with a G35 coupe tonight and was very impressed with the TL. I didn't think i was gonna really be able to run that close with him. I couldn't get as good launch as him because of traction but by second it was bumper to bumper. Im acutally thinking of really getting the SC if it ever really comes out.

Hey when I fart I am pushing 2 PSI but that’s not a constant PSI. It sometimes will spike to 5 then drop back down and eventually hit 0 PSI. If I had constant pressure though I think I would blow an O-ring and that would be bad. Those aren’t easy to fix you know.
