Thanks guys. I've heard of Ed Curtis many times and I think that's the route I'm going. I also ordered a snow performance level 3 meth kit. So if my calculations are correct and I run low boost levels I should be fine. I've been doing a lot of research on meth/inj and it should allow me to at least feel safe on pump gas even if I don't go with sc or turbo. But if I do I should be able to run low levels especially where my block's not stock. Now my next concern will be my pro motion trans thats only good for 450hp and it's still virtually a t5 so I'd say 350hp is pushing it. Also I haven't really got any ideas on what I should do as far as MAF/Throttle body ect...I need i fo from tb to cai what should my set up be there. As of now the maf is only good for 19lb injectors but the tune i guess set it for 24lb injectors. I really think I want bigger injectors and I know before I buy them I need to know which route I'm going. Sorry for any typo's I'm on my HTC One. Thanks again. I'm using all this information. So when I call Ed or anyone I have an idea of what I need.

Don't boost that engine. Pull those heads off and sell them, then buy some with a larger chamber. That will drop your compression. Running a supercharger or turbocharger on an 11:1 engine is not a good idea. You'll need more than 93 octane fuel, and meth injection isn't reliable.
I hear ya. I'm pretty sure that with meth I could run low, low boost to squeeze an extra 75-100hp out of the car but i will probably stay N/A.

If your dead set on a power adder and don't want to change compression hit it with a shot of nitrous. A 100 shot should get you into the low 400hp range. Nitrous works well with higher compression engines.

I'm running a 100 shot right now. I just wanted a little boost and have seen people run meth with 12:1 and supporting mods so after reading all the coments and continuing my research I think with the right supporting mods and of course a spot on tune I can run low boost and be ok. So that's why I ask. I also asked what tb/injectors/maf ect...I ask because I take it all in and make my decisions. I mean after this post I've found the guy who will be making my cam, picked up a nice snow performance stage 3 set up on sale and should make some decent power.

If your going to boost the car. Injector size should be between 39 and 42 pounds. You'll also want the biggest MAF and throttle body you can find. No sense in throwing a restriction in the path of All the extra air. Think 75MM. Replacing the heads with something that will offer a lower compression ratio isn't a bad idea. Your going to have a lot to tune for with multiple power adders and meth injection. Good luck. Your probably going to need it.
