An interesting response to my e-mail I sent asking about the limits of the LSJ intake mani.

As long as you have a properly-matched port, the intake should be useable to 500hp. If you would like a custom intake, we recommend www.batesengineering.info.

Opcon rates the laminova cores at just only 100hp each, on a straight though design. (no sharp bends or flow restrictions)
There isn't a hope in hell of getting a reliable 500hp on that shitty manifold.

The manifold and SC system on the LSJ was not made for the LSJ... it was made for the Eco Cavaliers and Sunfires.... it was never made to push more than 10psi though that system.
Unfortunately, when it was put into a Cobalt and sold as an SS model, people started to mod them up more heavily.... and eventually learned that they are just a piece of junk.

thats what im saying the blower doesnt make 12.5psi its 12.5 psi where the gauge reads from inside the intake somewhere where it has all gone to ****.
does anyone honestly believe a gen 5 blower can be this bad? no one else with these blowers needs a cooling system. i just think gm should have thought it through a little more. but i guess if it wasnt made for the cobalt then i cant complain, we just got stuck with a bad product
and for the record my head didnt explode, i know a bit more than i lead on, thats why i have a lot of custom things on my cars that all work very well. i was just bringing that point across that the blower doesnt make 12.5psi

i didnt find much about it on the web. any pictures of the setup out there, or even better videos like the lsj video of how it works floating around
