3.6L DI motor gains over 31 rwhp!!!

[Fire and Ice]

Thank you all for your patience and we are happy to announce the results are in! Attached are dyno graphs from our 2008 CTS 3.6L DI RWD.
Baseline run: vehicle produced 263.0 rwhp and 241.7 lbs/tq.
Adding the new Corsa Exhaust power jumped to 281.1 rwhp and 255.3 lbs/tq. for an increase of 18.1 rwhp and 13.6 lbs/tq



From here, we added our intake system and power jumped to 294.2 rwhp and 261.3 lbs/tq for an increase of 13.1 rwhp and 6.0 lbs/tq. Total gain in power was 31.2 rwhp and 19.6 lbs/tq. from just an intake and exhaust.

I'm really interested in knowing what 0-60 and 1/4 times will be with the added power... Any ideas?

Just guessing of course, but I'd estimate a drop in 2-3 tenths if track/driving conditions remain constant. Just my guess though...

Price?
When available?

Thanks,

Aren't the horsepower ratings that the automakers give now are the rating at the rear wheels?

[Southern]

No. They are however the hp with belts, alternators, power steering pumps (if used) etc hooked up. But they are still calculated on an engine stand.

Nice results.
Do you have any video clips, so we can hear the sound difference with the exhaust?

Is there any resonance in the car from the exhaust?

Thanks
Jim

Wow! Thats quite impressive. Hope we can hear the exhaust as well. No effect to the warranty either I would imagine.

Thats quite the bolt on improvement..

10 percent for two mods..

How much?

That must be one restrictive exhaust/intake from the factory! Now I'm curious what all of that would do along with a custom tune.

I've had Corsa before on a V6 and there wasn't even a hint of drone, so I'm curious to see how it does on this CTS. But more important, how does it sound inside and out. That was my only complaint with the Corsa + V6 combo... it sounded like a 4 banger.

On a V8, they just sound mean.

WOW when will all of these parts be available?

[concorso]

Wow! Good numbers D3! With a tune, you should be close to the numbers from a stock E46 M3!

sorry for the wait on Avail. and price, we are out of the shop over the weekend and we will get back to you as soon as we know.

Thank you,

I'm still waiting on pricing from Corsa for the exhaust, but I would estimate that pricing would be around the same as for the STS at $1195.00 MSRP. As for our intake, pricing is estimated around $450.00 MSRP and will include all necessary hardware, clamps, etc. That's just a guess of course.

Although I don't have an estimate on when these parts will be available, we are taking pre-orders now for those who want to get in line. If you're interested in placing a pre-order, PM or email me your contact information. I'll need your name, mailing address and phone number. When we have a set release date or more information for these items I'll gladly update everyone.

Thank you and have a great weekend!

Was the ECM reflashed/tuned or were the gains just from intake and exhaust?

Yeah, I've been wondering this since I first got on this board...it's the reason I got on this board lol, but I'm glad you guys are taking ur time.

Fire & Ice, do you know a dealer who will install these things, mainly the intake? I know you were telling me which dealers you worked with, but would any of them install it for me? One Service Rep. told me it would only be under warranty if I get a dealer to do it...or a dealer that they own to do it. In that case it was Lou Ehler's dealership and I remember you said you worked with Coast Cadillac I think. He said since they own Coast, if I got Coast to install it, then it would be under warranty for at least Lou Ehlers and Coast Cadillac.
