Is there anything special the motor needs in order to run spray? Like with a turbo, I know you need a lower compression engine in order for the tuning to not be so critical. Is it possible to have a higher but not super high compression motor to run on spray? And what about internals? Im assuming all forged internals? Any tips on that? What about any good nitrous write ups so I can learn more?

Just FYI, Im looking to build a 350 horse 350cubes and run somewhere around 150-200 shot. Im deciding on 350/350hp is to keep the streetablity around town, but when I need it, I can unleash the terror, like on a local cocky S2000 kid around here.

Does that sound reasonable to you?

Thanks, Lance

 

Same rules apply, you can't really run very high CR or else you have the same problems as with a blower or turbo. 9.5:1 should be fine though, just don't try it with 10.5:1 unless you're running full on race fuel in it.

150-200 shot - nitrous timing retard perhaps. Or pull it back yourself before you're going to use the nitrous. Around 4* or a bit more. A stand-alone fuel system for the nitrous is a nice addon, not too difficult to do. Not sure if you need it with that nitrous level though.

Wider ring gaps on the top rings is pretty important.

Pay attention to having a flat deck, flat heads, good head bolts, correct torque, etc.

A nitrous cam is nice, but you suffer 99% of the time when the nitrous is not in use, in order to feel the gain that 1% of the time the nitrous is on. I wouldn't use it in your case, just suggesting it. Split pattern cam for sure though.
