I know that nitrous likes a wide lobe seperation. What kind of differences will you see with a tight vs wide LSA on a nitrous car. Has anyone done any testing?

i did some testing, a few cams, seemed the 112 was the best with my small motor. the esp1 cam made the most power all the way across, and was accualy the smallest one tested. she made more power na and on the spray. i also ran a t-rex, and a BIG custom grind.

 

I've seen the best results with 112 also FWIW.

 

Yhe cam we had in my 395ci was a 248,261, 651 ,651 on a 114 and it made plenty of power.

 

I like my 520/520 236/248 on a 113 in my old school sbc in the 96' S-10.

 

112 LSA and up will be fine, anything tighter and you'll lose some of the gas when the exhaust valve opens, to much overlap.

 

Whats soem info ont eh ESP1 cam? I have no clue as to what it is

 

what about a 3000 stall compcams 224/228 114lsa and patriot ls6 heads assembled with there valvetrain including dual springs ect and a 150 shot... 10.5:1 cp ratio.. how ya'll think that would work running 93-95 octane pump gas???

question really is.. how will that work with the 150 shot.. is that a good setup to see some gains on nitrous?

 

Thats should be decent cam for the spray. That converter will loosin up nicely too. Should go 10's.

 

the esp1 cam is accualy the NA version, we changed a couple things for the N2O version, so its more of the ESP 1 N2O.
the cam specs are kind of a R+D spec. meaning we dont want to give out the Number unless it is purchased, but its a 232/236 cam with a different then most lift and lsa. but after cam swaps we found this to work the best with the smaller cube motors. both NA and on spray. my car was the N2O test bed. my specs are stock cube, good rods, good pistons, and ls6 heads. all bolt ons, and a 200 shot from a Custon NOSzle system. the 9.9 was befor my seperate fuel system, and on a bad WOT switch. since i have gone a 1.4 60', but lost my traction 100' out.
hope this helps
