this is true....
but im just talkin about a stock engine... that you dont wanna abuse to bad.
this is y i like the RPM based controller and for this reason only!
on my vette it allows me to pick say 425 rwtq as my tq limit through out the RPM range
ill lock out first and start with second.
and my car redlines at 5600
so well say i want the 425 ft lbs of tq by 2750 rpm... wellll
before that rpm ill have the n20 come on gradually (WOT of corse) until it reaches 425 rwtq and then have n20 added to the rest of the rpm range as the tq qould normally fall off to stay the same... thus keeping the tq flat from 2750-5500 rpm.
as you know tq is very great expecially in a v8 in the low rpm range and then is non existant in the higher rpm ranges as the time between spark is decreased. what this acomplishes say... with the same bottle of n20 and the same tq (cylinder pressure) exposure to your engine, accomplished more hp... alot more high end hp to be exact.
as you know hp is a derivitive of tq vs rpm. i believe hp= tq x rpm/5250. so technically the higher rpm you go keeping the tq constant then you are constantly gaining hp.
my vette made 360 rwhp and 515 rwtq qith a 125 shot non progressive controller stock engine. with the controller it made a constant 425ft lbs of tq and 480 rwhp. more hp and going a lot lighter on the engine. all on my stock engine. but agian on a drag car or a car with a built engine... hwats the point? other than to keep the tires from breakin loose and if you had a built engine i hope ure running slicks any wayz.
the difference between a rpm based controller and a plan n20 shot(yes i know a very very shitty drawing)
RPM based

any wayz just a thought and also the only reason im running it it also cost $200 so a good investment to keep my stocker going a tad longer on the juice
