Yes you can use N2O as an aftercooler for a boosted application. However you have to keep the shot low in order for it to only cool the charge and not cause detonation anyway because of too much oxidizer.

You're going to be pushing the limits on that block for sure. Look into an aftermarket block if you're looking to make any more power than 550 or so.

ya im starting to get worried about the block.i think i will wait until i have a a/f gauge and a tweecer before i spray since its so cool outside i wouldent think getting heat soaked and loosing power should not be a problem in 30 degree weather in fact i was thinking of bumping timing to 11 or 12 base should give me 20 or 21 with all timing in with spout in am i going in the right direction with colder weather or does it have little affect internal.anyone feel free open for suggestions yall or really good on sc and tuning i could not have car running so good without this site

Here are 2 threads on 351 stock "block" and 750hp -1000hp Turbo cars that stay together, Of course a properly built engine is the key and that is not a guarantee, just read them then decide.
1987 Mustang GT, 351W Stock Block, PT88

Let's see those stock block 351w Turbo Combo's!!

I've seen a few centrifigal systems set up with Nitrous after the supercharger. I have also seen roots/screw type supercharger setups with nitrous on the front end of the supercharger. It will have the same impact before or after the supercharger plus it will cool down the supercharger itself.

i WAS THINKING OF SPRAYING JUST BEFORE COMPRESSOR LIKE THE METH INJ. KITS DO.BUT NOT SHURE IF I CAN DO THAT WITHOUT HURTING SC.I PICKED UP A 69 351 W MOTOR RUNNING SO THATS MY WINTER PROJECT.I NEVER DYNO THIS MOTOR(302) BUT IT RUNS 125MPH IN THE 1/4 SO I THINK IM CLOSE TO 500HP AND DONT WANT TO PUSH BLOCK ANY FURTHER.THANKS AGAIN FOR ALL OF THE GOOD ADVICE.SOORY ABOUT CAP'S

with a supercharger i would go with meth injection nitrous is only quick shots where meth is constant spray and will last longer and not as harmful as nitrous .
