hey guys, ok, here is the graph to 7500, i did a pull to 7800 and everything was good. i am going to have it back on the dyno soon and see what else i can do with it.

BIG thanks to Tony at Motordyne Engineering for sending me a rev up lower plenum and possibly doing some magic to it.

with that plus some headers, that should dramatically change my curve up top, although, its still usuable power right now.

next is i need to get more air into the motor and port out the plenum neck, TB, maf housing and piping..

thanks everyone and i am going to the track on friday night!!



i will get to 8500 here very soon, i just dont want to wreck the motor just in case, i want to have some fun first!!

PV=nRT! Generally, because the pressure decreases so rapidly (when exiting the bottle), the temperature decreases substantially.

Car looks great. Congrats so far on all the work. This is looking very promising for future N/A guys. Guess they all know where to take their cars for that BTW I love the poster of Abbie welding that you have up.

additionally, the nitrous is undergoing a phase change.......in the bottle it is in a liquid sTate and can only be so due to the high pressure. once you release it to atmospere, the huge pressure drop ( again.....PV=nRT) causes the nitrous to return back into its gaseous state.

Very nice Jermey. What fuel are you running? It will be interesting to see, if a street gas tune is possible.....with some super duper low timing.

Great preliminary numbers!

actually, P1V1/T1 = P2V2/T2

Bernoulli's Principle people.... as pressure increases velocity decreases, and the inverse is true and when you go from high pressure to low you drop in temp.
