10.8:1 CR + boost?

if you kept the boost low i think you would be okay. like an a-trim would be a good little s/c for something like this IMO.

about the nitrous performing a cooling affect. From what I've found and read about, it doesn't do anything but add nitrous. the cooling affect is minimal. I was looking into this a while back when a guy i knew was going to sell me his dry NOS kit for cheap. Increased cylinder pressure is increased cylinder pressure. your better off getting methonal injeciton for its cooling affects rather than N2O. nitrous is just going to raise the cylinder pressure rather than lower it from cooler air.

an a-trim would be a major bottleneck on the intake side with his combo. i wouldnt go anything less than an s-trim.

Yes.

I dont think Id boost a 11:1 motor either.

Id spray the hell out of it, but I wouldnt boost it.

IF you get a wet kit all you would really need to make sure is the pump end. Lines maybe if your making some big numbers (like 500wrhp+). I myself have 10.33-10.6 comp. on my setup depending on what end of the +/- production variance on the cc of the gt40 heads. I am running a 150 and a slightly "modded" 175 setup if I am close to making some retarded run (like say I ran really low 11's I may swap out the 150 nozzle for the 175 setup to see if I can muster a 10.99).

To me with the hp you would gain with 5-6lbs of boost v. a 125+ shot I would go with the bottle. Say you make 20hp per lb of boost (not too far off what people see) you would need to run 5lbs just to make 100hp...a 125 shot would be that and give you more trq. Now if your talking running 15-20+lbs of boost I would say boost it...but thats not going to happen with an avg. 10.5+ combo.

From what I have read/seen/been told n2o loves compression...to extremes like 13:1 or something.

Your car would be absolutely sick with a 150 shot.
