Not much, I would think that even 6 psi or so would be pushing it. Any more and you'll need to start thinking about water injection , higher octane fuel and such. Those motor's aren't really designed to be turbo'd or force inducted, they're designed for NA power hence the high compression.

6 psi was the max I could get, but with aem methanol injection and cam gears I was able to get it up to 10psi without knocking. If you need any help let me know.

I pieced the turbo set up together myself, and as far as horsepower 230-240. Just to give you a heads up this set up cut my mpg in half and I get about 18 mpg now.

18MPG is not too bad, I was only getting 25 mpg on NA but I guess my ECU and some other stuff were never working right so I was always running rich. Show us some pictures of your engine bay jmeyer

There are gonna be a lot of variables with that, like tranny being used, mods, which style car you have and other stuff along those lines. To be perfectly honest I don't know any 1/4 times for the 4age but I wouldn't expect blinding fast speeds or anything.

If you need any help let me know. Your setup has 8.5:1 gze pistons you said in your thread, he is not going to get close to that on stock silvertop internals. My large port is 9.4:1 my small port is 10.3:1 and the silver top is more than that, 10.5:1.
