Please bear with me guys. I may never add nitrous to the stroker I'm finally taking action on to build. Yep, I sent the deposit on the BME aluminum block, so I know that isn't much $$ compared to the total cost, but every journey begins with the first step. I know I may struggle for a while to get traction, to keep parts from breaking, or after experiencing breakage, see that I have to make different choices.
Let's put that aside for now...
I would like to hear from those of you who have experience with nitrous motors. I've read there are things done in the build to accommodate or prep for nitrous. The "baseline" I anticipate is the BME block, 4.25 stroke, 4.5 bore 541 cu in displacement. TF 270s with the Weiand "tunnel ram" intake 6bbl top, Nitrous Express 2bbl spray plate(s). Cam profile should be fairly "mild" because I am counting on the displacement to lend a good bit of HP and torque to the total, and I'm only looking for 6XX HP and say 650-700 ft lbs torque.
If I see that I need a kick or I may not beat the guy I just picked up a grudge race against, or I've done what I can or am willing to to get the best ET/MPH but if I could get a little more I'd break into the next lower second ET or turn the MPH into the next decade, in other words I anticipate using the nitrous as an "emergency" button....
Is there a HP number that is low enough to not have to do anything special but high enough to cut a few tenths? Around what is that?
If a 6XXHP/690FT LBS engine in a 3,800 pound car needs a 250 HP shot to make it worthwhile, what do you do differently in the build AND what are the NEGATIVE effects of building the engine to accommodate nitrous, when you aren't using nitrous.
THANKS to anyone who will entertain my questions, I appreciate it.
