All, right guys, maybe u remember my build, if not all u need to know is that its LS/Vec w/ p30 pistons and GSR head w/ a JRSC@9lbs and tuned uberdata.
Well i finally got the car tuned (again, lol) and it goes great, runs good but isnt filling my needs SOOOO my plan:

Change the p30 pistons w/ forged pistons yeilding about 10.0/1 CR on stock rods and sleeves, keep the 9-10lbs of boost and and add a 50 shot of wet nitrous.Also keep in mind the water/alchol injection will be installed and operating by this the time.

The reason I choose nitrous over more boost is b/c the moost boost u can run on these chargers is about 12lbs and that still wouldnt be enough to fill my needs.Also, the nitrous would be used on ocasion rather than more boost being there all the time.I figured ill have 2 maps made for the uber, one for all boost(daily driving) and the bottle(track).

Please gimma a hand with this, its driving me crazy.

 

bump it

not to mention heat soak, after my 2nd run my manifold was already getting to hot

 

i dont follow

 

bump for lack of help

Your on the right track with the 10-1 comp , NOS works really well with blowers too.
I would loose the water injection, We have always made more power without it on the dyno.
I would also try to keep the boost around 10 psi. on an LS Vtec at 12 spi I have seen temps at 270 deg discharge.
We made 298 whp on my B20Vtec at 8 psi, at 9 psi it lost power because the intercooler couldn't keep the temps down. The motor is 2.1L so 8 psi on it is like 15 on a GSR ( The blower is spinning 18,000 rpms).
If your keeping the Ubdata , find someone that knows how to tune a supercharged setup.
Good luck!
