That is a small ass 1.7 liter blower that already had to be revised in order to be efficient on a stock ZL1/Z06. It is already being spun close to it's max. Can you spun it more? Sure. Are people claiming it can make "900 RWHP" or whatever? Sure. Is it efficient or reliable? Hell no. Now if the OP is looking to drive the car only every now and then and possibly take it to the track once or twice a year for a couple runs then fine. But outside of that I would not waste money on that stock blower. If money is an issue then don't mod at all. Plain and simple. Or go with a 2.3 liter aftermarket blower instead of a 2650. Or opt for the cheaper Whipple 2.9 liter blower. Or wait a couple years and save money. But there will be a big difference in performance and longevity between someone trying to be cheap and force a small blower to push more than it should and work inefficiently or someone who spent a little more money for a completely efficient setup that works very well and has much more potential and isn't squeezing every last ounce of power out while dealing with heat soak.

For the record, most shops can do a complete build for somewhere around $15K or less. This would include upgraded blower, cam, ported heads, install, etc...give or take a few items. And you wouldn't even have to think about heat soak. And you could sell your stock system if you wanna absorb some of the cost. It isn't much. And most likely you'll be in the 800+ RWHP range on pump gas. E85 or race gas would net even more. And you'd be nowhere close to maxing out that setup.

But to each their own. Do whatever you want. I've had my ZL1 for 4 years now and am finally deciding to go with extensive mods. And I got a very decent deal for the setup I am going with. It is simple, easy, no pushing this to it's max or worrying about heat or trying to string out "900" HP. If someone wants to go that route tho then good luck. And I hope they don't eventually want more because then all that money on porting and strapping it to it's max will have been a waste.
