Does anyone know what GM did to make this car put down 180 hp to the wheels N/A? From the spec sheet, it doesn't look like they did that much... although I'm sure they omitted a lot...
those numbers are most likely at the crank which is about 15% more than what you actually would get at the wheels, also has a slightly higher comp ratio with a good size exhaust, i was getting like 148 at the wheels NA so thats like 170ish at the crank

ECU tuning. That's where it's at. But read carefully. The spec sheet said 180.3 bhp. That's "brake horsepower". In other words, that's power measured at the crank. To the wheels it's prolly more like 150-160. Still pretty impressive for bolt-ons. But it's from the ECU tuning.

Not trying to muddy the water but go to RSM site and click on the gallery. Take a look at the Cavalier RS-M package 195 HP NA $ 6000.00 Cavalier SS-R package 180 HP NA. $5000.00. Both packages come with susp and body mods brake upgrade tire and wheel upgrades etc. Have a look.
Thats Him Officer The WICKED One.
OK, but that's not the point. He wanted to know how GM did it. On top of that, the GM package I'm guessing is only for the Ecotec, the RSM package is available for more than just the Eco.

I was going to say software too, GM didn't change anything but the software for the Duramax diesel pickups from '05 to'06. The 05's were rated at a little over 300hp, and the 06's are rated at 360HP/650TQ. I drove one today (perks of the job, I'm a Medium Duty Service Tech at a Gm dealer) and it felt more like a sports car than a 3/4 ton pickup. It breaks the rear end loose at ~15mph when the throttle gets mashed to the floor.

I did miss the "bhp" meaning "at the crank"... my mistake...

Ok, so basically... Um... why isn't GM offering these ECU re-tunings?? Jerks! I really am starting to get aggravated by this whole "Hi, I'm GM! Look what I can do to Cavaliers and Sunfires... we are able to gain 40hp from basic N/A mods on an Ecotec but we're not going to tell you how to do it specifically... We can make gorgeous body kits that we're not going to offer you, our loyal public..." grr...
[/RANT]
But really I wish GM would start offering some of the parts from these "concept cars" or at least tell us how they did some of it...
they been doing this for years the best stuff they made is never put out, like the turbosport cav, they could have put that car on the market for less than 20G and it would have destroyed anything in the sub 25k range even the srt-4 but noooooo they bring out the heavier slower cobalt ss for 23-24k that can only barely keep the srt4 in its sights

tim, you see...that would make sense!! this is why they are starting to go under.

emissions compliance is 1 reason, and supporting all those cars warranties is another. Theres a truck in my shop right now that has a whole lot of the diesel power hop-ups (bigger turbo, Banks power kinda stuff) on it, and a blown Allison trans. A lot of times the engines can make the power and make it reliably, but the rest of the car, whether it be the trans, the driveshaft, the axles, etc can't handle it. If they put the components that can handle the power in, the cost goes up.
Like the Duramax diesel pickups I mentioned earlier, they didn't up the HP until they had a beefier trans, namely a 6 speed Allison over the old 5 speed Allison.

thing is, GM could easily come out with a real, fully factory-backed aftermarket program and make a @!#$E-load of money off it. Think about it... TRD, Mopar, SVT, etc. I would venture a guess that Toyota, Dodge and Ford and all the other companies with one make a lot of money off the aftermarket customization market. Why won't GM just get on the bandwagon and realize there are a heck of a lot of young people who are making a lot of money and want to spend it on their sport compact? Silly GM... oh well, at least it seems they're improving...
GM doesn't really have the commitment it takes. Look, I'm a Honda guy. Always have been. They have better factory support. There's spec racing like the Honda Tuning Challenge. Racing developments from places like Hondata and Mugen make it into showrooms in Japan. A lot of that stuff gets imported here. Mazda, Toyota, Nissan, they all do it. THey take their racing developments and put them in their showrooms. WHen it comes to GM, the only car that gets that treatment is the ZO6. It's nearly identical to the race prep version, but no cage and a full interior. They support Rhys Millen's drift effort, but when it comes to the compacts, GM wastes time on sh*t platforms and use old technology for the public, and puts all their tech into concept cars that will never see production, and factory backed race teams, then don't bother to tell us, the public what they did or how. They sell the blueprints and parts lists to build a monster 1000hp Ecotec, but leave the ECU tuning up to us. Why? Makes no sense to me. And to make it worse, the program encryptions are nearly impossible to read and make any sense of.

that would be GMPP (gmperformance parts) , ( and SLP to fords SVT) there is plenty of aftermarket support from gm for f bodies w bodies vettes even trucks.gmpp makes an entire catalog just for the ecotec alone im sure you already know. while most of the parts are for internal and some race only , you can do all of those other mods 4-1 header, exhaust that the show car did and expect similar results. most eco cars on here with those mods are in the high 14s that would take about a 180 bhp engine in our cars to do so really its not that far off.
15.4 @ 89mph
So does anyone have pics of this particular concept?^^^
and it is infact an Ecotec engine right, aluminum head......10:2:1
I have one true love in my life...And my girlfriend sits next to me in it
n/m....just realized I was wrong about the compression ratio being the same.....but still does anyone have pictures of this one^^^
the only ones I could find were the yellow 03+ and the grey 2001 turbo's that and full out drag cars.

Gm has GMPerformanceParts, and also works with SLP very closely. They mostly stick with their performance cars ie: camaro, gto, vette, and some trucks.
The Cavalier is a dead platform. It would not make sence for GM to invest any more money into it. The Cobalt on the other hand... I could see SLP coming out with a package (if they haven't already.)
This is like asking Ford to come out with tuning software for the Escort.
BHP = Break Horsepower
WHP = Wheel Horsepower
There is a difference between the 2.
Also, higher compression can help with that and changing perameters in the computer as well (like ignition and fuel changes).

maybe it's got the same motor thats in the gt-s

What? The Celica GT-S?
It says right there...The L61 Motor... L61 = ECOTEC

Huh?! Maybe they should include all that on the parts list in the toop picture. Reading that you're led to believe it's just a stock internal engine that's been tuned. They lie. Sinners.
