guessing your going to keep the forged 2liter for a backup right?? because the stock 2.2 is right at its edge with the 12psi from the stock blower. my buddies 2.2 slapped a rod at 217 hp and thats about 240-250 crank(just like GM said). similar to what the redline puts down stock. just a heads up to reconsider the pulley upgrade.
should be a little quicker too since the cavy has a 200-300 pound weight saving over the redline and cobalt ss
If your buddy snapped at 215 then something wasn't right most likey his air/fuel ratio. 2.2 eco is rated for 300 and I've seen some people run some pretty decent power to it. 240+whp on stock internals. Only time will tell but I'm looking forward the the results on this.
Between the weight advantage and higher compression. Really makes me curious what kind of power it will make and 1/4 mile times I'll run.
Hopefully the install will happen this weekend, I'll try to update with pics as I go given the chance.
