ok someone give me an idea how much nitrous i can shoot to a motor with 13 to 1 compression. this is a 0 deck motor. dont want to blow it.

Just keep adding until something goes from the inside to the outside or something turns runny (melts) and then back off by 25 hp.

Norm, I have been running a 150 shot, but only about 8:1 compression. See if you can get hold of Barry Harrison. Pretty sure he has compression, judging by his et's on motor, and he is on gasoline, not moonshine. If you planning on "Georgia Moon", I would contact Charles Myers, Cox Bros, or Will Burns.

Norm, What kind of pistons and rods? A big shot with alot of compression takes good parts. I feel that a big shot on an inline motor needs a fogger system. I run alcohol as a primary fuel and 116 racing gas as enrichment. Coxs' run alcohol on both sides. Start off rich and back way off on timing and tune it in.
