im going to be getting a new cam, i was thinking abouta gm 847 232/242 @.050 .539/.558 lift 112 would this cam be good for n20 and superchargers? what do you look for in cam #'s for blower and nitrous aplications i dont know anything abput cams so any input would help. thanks

 

Hrm.. depends on how big you'd like to go really....

I think a Comp Cams 224/236 114 LSA would do you nicely

 

how do you think the gm847 would do

 

I'm not too familiar with that cam, so I'm not sure really..

I know the 112 LSA isn't ideal for forced induction / nitrous applications.. usually a little higher LSA works out better.

 

The LSA is just part of the equation. You have to look at the duration numbers. You definately want a split duration, with some more duration on the exhaust side. However you don't want to get into too far on the split. For instance the 306's duration numbers are too far apart. Leaving alot of overlap, and lost of boost/n20. It's all a game of duration. If you do the math at 230/236 on a 112 has LESS overlap than a 306 on a 114 or even a 115. Also a nitrous cam isn't really going to do anything too much more, unless you start getting into some MAN numbers, like 200 shot and up... Get a Nice NA cam. Personally I dig that 230/236 series of cams...

 

talk to seth at cmotorsports.com he'll help you out.

i ordered the c.c. 224/236 with the 114 lsa as mentioned above.

you need a nitrous/sc. specific cam, they cut the vavle overlap so you don't loose your boost through the exhaust!!!!

talk to seth he'll set you up!
