  • pistons cause a drop in power??? yes because shops do forged internals to loose power. Myabe if your cars only at 15psi you loose power, try throwing some more boost at her and see if you loose power over stock internals.

    why would you do forged pistons if you loose power?? weird.....

  • To be reliable so you can make power in the future? It seems nobody ever understands this concept unless they actually build a motor themself.

  • you have a fully built cobalt ss spraying a 75 shot and barely beat a turbo cobalt with intake exhaust and a tune. thats pathetic.

    last i checked a 2.8 pulley on cobalts were making about 17-19psi of boost.

    your only on 15psi because your car is "un-tuned" so you say.

    never heard of anyone building a motor, doing injectors, (with that right there you need to re-tune) 2.8 pulley, pistons, header, and spraying.

    if its not tuned thats just your stupidity

  • How does tuned or untuned affect boost on a roots blower? Damn sure it DOESN'T. The car is on 15psi, stock pistons or forged, it's still 15psi until he changes the pulley.

    For the record, his "tune" consists of injector scaling (so the car runs), retarding timing from stock, and attempting to dial in a/f with a tailpipe sniffer on a catted stock exhaust. That my friend is what I consider, UNTUNED!

  • Dude in turbo cobalt is wearing chick glasses, loses to an sc, and doesnt no lift shift the bitch. I bet a race from a dig would result in both you nubs stalling em out.... fhags

  • nice sunglasses little girl

  • @N3CROKiLLA33 theres a reason they didnt make alot of yellow just like they didnt make alot of shit brown and puke green.

  • nice glasses on the driver of the blue balt cute hahaha

  • They only produced 2,537 Cobalt SS's in 2009.

    120 of those are yellow.

    My car is 1 of 120.

  • @punkblindchild13 If you avoid detonation hypereutectic pistons can handle ridiculous amounts of power, more than forged pistons can handle. But when detonation is thrown into the picture forged pistons come out on top because they are softer and will dent, deform, bend, melt etc before they outright break. Hypers will break like glass under detonation but under normal combustion they can handle a ton of power. Hope this clears things up.

  • @punkblindchild13 Hyper pistons can also handle detonation because of those same thermal properties. They are better able to absorb and transfer heat (detonation, preignition, and plain old horsepower) than forged pistons. They are also harder than forged and can take a harder beating without denting/wearing down (simply, they are stronger than forged pistons). The downfall of hyper pistons is that they are brittle and therefor when detonation occurs beyond what they can absorb, they break.

  • @punkblinkchild13 Cast pistons are the cheap pieces for low-performance vehicles and can even be used in n/a mid-performance vehicles. Hypereutectic and forged are a wash, they both have advantages and disadvantages. Don't make the mistake of thinking that forged are "better". Hypereutectic pistons will always make more power then forged, all things being equal, because of their thermal properties.

  • no tune with a 2.8 and 75 shot the car must run like crap the CPU thinks the car is fucked up. plus for what it has done seems weak i have a similar set up, 2.8 pully @ 19 psi, cai, 75 shot, full exhaust, 60lb injectors. dual pass with heat exchange and HP tuner custom tune and i destroy TC cobalts. a tune can increase your power and increase the most from your Nitrous system. u should be pushing bout 320 to 360 whp with right tune

  • do yourself a favor.

    step on your sunglasses.
