Nitrous does have it's place, just like I said. Puts power in the hands of the people who's pockets aren't deep enough to run as fast as they want. It's a cheaper way to help get them there.
Bottles are not the same, as they have better flowing nozzels. The solenoids are no where NEAR the same from what I've seen. High HP pump gas set ups can't be had without power adders, nitrous being the best IMO to run on pump gas, as it cools down the intake as well as bumping the HP.
I guarantee you your 125HP baby rating from 1985 doesn't put down the same power to the ground as the one in '07. Things have changed. My last car picked up 194 rwhp on a 200 hp baby "shot".
I also had almost 20K miles on a little 'ole 306 with that 200 hit on it, no issues.
It's all in the tune, just like anything. High compression N/A, blower, turbo, or nitrous.
340'srule - you sound so ignorant telling somebody to "shut up" on a public forum. Grow up, take your pocket change and go buy some manners, and pick up some set up books so your not so ignorant on the subject. BTW- What's that "real engine" gain you for ET anyway?
