Well guys I had posted to all my ls homies that I dumped my 2.2 cobalt that i bought in hope of boosting, well i got too itchy and bought an 05 Cav Coupe 5 spd base. I did a few mods like a short throw and a GMPP S/C Kit.
I currently have 14" steelies wrapped in Goodyear assurance triple treads and a stock exhaust, aftercooler, and small intake mod.
My friend who is Bika on the forum owns a Cobalt SS S/C and I own him. By a car er some. Thought you guys would be proud of me Thanks!

 

nice kill man. what mods if any were on the cobalt sc?

 

stockish, boost bypass

 

Good stuff, was the ss.sc stock tho?

 

Wrong section? neat story.

 

a stock cav with the gm sc kit beats an ss/sc?


surprising.

nice work on the modding.

 

cavy's a lot lighter... especially with 14" steelies and no power options....

Almost makes ya wish they made a stripped down SS/SC... you can drop a lot of weight if you ditch the power equipment.

 

cool stuff man....how big is the blower?? how much boost??? any pics. of the cavi??

 

Understood. though i was under the impression, that because a normal N/A motor has a higher compression, boosting is limited down around the 3-5psi mark for the most part....and generally was under the impression that they were pushing a fair bit less horsepower.

I guess maybe they are just that much lighter that the HP difference is negated due to weight?

Again...im not ragging, im just surprised. thats some nicely modded cavy to pull an ss/sc

 

hes got the eco, if he had a GM blower on the LD9 the outcome would be different.
non the less , good work

 

10 lbs of boost it is the ld9. Its the ss blower. m60.

 

i can go way higher and plan to. as far as boost goes.

 

its not an LD9, its an L61 ecotec 2.2. LD9 is the twin cam 2.4 in teh 96-02 j-body. the blower is the same as the cobalt ss. M62 and its pushing 10psi. I did about half of the work on his install of the s/c and custom heat exchanger. yes he does own my SS we swapped cars for one race and the outcome was the same. (we thought my shitty driving was to blame. he's driven my car several times so he knows the quirks of the SS) My car is stock except for the boost bypass mod and a K&N intake. im even on 16" rims for winter that are 4 lbs a piece lighter than the 18"s. (traction wasnt an issue since we usually go from a slow roll)

this cavy is one hell of a sleeper though. people dont know what the hell is goin on when they race that thing. stock down to the exhaust and 14" hubcaps

all i can think of is time for stage 2 and some goodies

 

well i don't know how high the compression on his cav's motor is, but as long as it isn't higher than say, 10ish:1 and his internals are stroong enough he can run higher than 5 psi. boost is basically like extra compression, so he is just going to have to run higher octane gas, and keep the temps down so he doesn't knock. about pushing less hp... all things being equal, higher compression always means higher horsepower. Boost or no boost. 5 psi can be handled fairly easily by most motors and many can go higher. i havent really seen any boosted non ss/sc cobalts on here, but on the mustang forums there are alot of guys running north of 10 psi on stock blocks and tranny's which is fairly common on alot of cars. as long as everything is done properly, i am sure he can handle alot more than 5 psi.

 

I think that's the single biggest mistake GM made with the SS/SC. "Here's a decently fast car. With 500lbs of useless weight added! Enjoy!!!!"

 

don't complain to me about extra weight, my hood weighs like half as much as your car. LOL.

 

Sounds good man. You may want to invest in HPTuners, and larger injectors, as well as a wideband in the future. That would give you a hell of a lot more tunability....

Do you have any pictures that you can share with us?

Chris-

 

There's a guy I met at a meet in Mooresville that's running our M62 blower on a '04 2.2 cavy. I believe he's pushing 230WHP... at less weight...

Those cavy's can be really suprising... if done properly.

 

You do realize boost likes low compression right?

 

yes, but you do realize that higher compression will make more power with boost or not right?


6 psi on a motor with 9.5:1 cr vs the same motor with 10:1 cr, the second will make more power if all else could be equal.

 

Not always true my friend. With cars running low boost a decent, but not to high compr ratio will put more power down. Like our cars having a 9.5:1 comp ratio. With a 8.5:1 comp ratio like built boosted cars run, they require more boost to get the same power. However, there is a cross over point where the higher compression engine will require a higher octane to resist detonation due to the boost being added.

 

the 2.2 eco has 10:1 compression.

clumsykx doesnt post much on the forums since he doesnt have a computer anymore.

we are currently battling heat soak, even with the aftercooler installed. the manifold IAT's still reach well into the 160*s on occasion. im thinking theres a pinch in one of the lines, or the pump we used isnt strong enough. we thought of setting up a sprayer for n2o, methanol, or co2, but thats only a temporary cooling agent. when it heat soaks, it will start to miss and run like ****. the ambient temperature is only around 40 degrees, i hate to see how bad this is gonna be during the summer. any ideas on geting it to run cooler consistantly?

 

Start drilling holes in the bumper and hood?

 

NJHK on this forum, can give you a ton of information regarding your setup. I was reading a lot of his posts over on the ecotec power forums. Looks like your rods are going to be the weak link over time....

Mmmmm, sleeper cars are always more fun....

 

The rods will only last til about 250-275ish hp
