150 shot

depends.
13 second ls1 picks up about .8-1. and 10 mph on 100shot
100 shot on a 9-10sec car wont pick up the same amount
 
my 357 cleveland went from a 10.70 to a 10.02 on a powershot and had a melt down from being lean so i say about .7 . what is your car running now a days
 
My stock 305 ran 15.7/87mph NA. 12.80/108 with a 150 shot.

My 396 ran 11.20/120 NA. 10.35/131 with a 150 shot.

A few examples I seem to remember.
 
I only have to run 1/8 mile, so far n/a it has been 6.5x @ 105 it should go a little faster n/a but I just do not have the time to work at it.

So if I hit it with 150 it should go 6.00?

on 175 I have gone from 12.80's to bottom 10's. constant 10.30's with 302" sbf and a e-cam. Most people see dismal results with 150-200 hp hits due to the tunes being what they call "safe" when actually there off in left field lifting ring lands and burning shit up from being to fat and over timed.

Depends on the motor heads , cam etc... lots of things come into play but if the thing has a good cylinder head and the right convertor/gear I'd be willing to say you could make it run into the 5.9's on 150-175. You can get at them a crap ton more to the 1/8 vrs to the 1/4 with timing.

Not trying to start a debate but do not want him to be miss-informed either, its pretty damn hard to melt parts from being lean. For example I have accidentally forgot to turn on my nitrous fuel pump (dedicated nitrous fuel system) and sprayed the car with a 93N jet for about 300 feet before I went wth and got out of it. Didn't hurt one damn thing, no melted pistons, no hurt rings, not even a rolled edge on the tip of the plug strap. Lean does no hurt stuff as easy as most think, over timed turns billet pistons into molted ashtrays faster than you can say oops. If your pistons melted the centers out it was most likely over timed, if they melted from the rings in it was probably too fat or ingested some oil.

shavin .5 to the 1/8 is still a whole dif ball game then shavin .5 to the 1/4
 
Thanks guys, I am going to do some local (South Carolina) class racing in the PTRA and last years record was 6.11 @ 111. So if I spray my car I should be in the ballgame.

my 355 went from 11.06 ro a 9.87 on a 82/82.....~200ish hp maybe?

An 82 jet doesn't always mean its 200, that's more of a ball park figure, depends on the plate, noids line size and length, bottle pressure.. everything comes into play but if i remember right you have to flow around 350lbs per hr of nitrous to be in the ball park of 100 hp. 82/82 is stupid fat on those plates at 5 psi flowing. In a car I tune I have ran 82/71 @ 5.5 and it was still heavy, 102/82 at 5.25 (1/8th only) and its stupid heavy. I don't feel comfortable moving below 5 psi so the next move in that car would to go 102/71 at 6.5psi and adjust from there based on plugs. The 102/71 would not prob be a safe gig for to run out the back door, 1/8 only tune up and I can get two or three more degrees in the motor in the 1/8 vrs the 1/4 depending on air conditions.

shavin .5 to the 1/8 is still a whole diff ball game then shaving .5 to the 1/4


Shaving .5 to 1/8 isn't as hard as you think. I know of cars that pick up a second to the 1/8 on a 82 jet and they are no slouch on the motor either.

Paul do you know how to read plugs? What system is on the car?

OK, I went to the dyno and the carb is dialed in perfect ( LoL) and on motor my little 310 makes 450 hp to the tire and 330 tq. Not bad if you ask me. So now if I hit it with the 150 shop I think it will be fast!!

UPDATE.............Ok so after I figured out how to wire this crazy setup I went to the dyno to spray it. I know not the best thing to do but I needed a ball park numbers to start with. So first pull with a 48 nitrous jet and a 40 fuel netted 530 hp and 500 tq!!! So then we moved up to 60 nitrous 55 fuel, 570 hp and 560 tq! So the class rule is 70 nitrous jet, so we put that in just for fun........588 hp and 575 tq......should run 6.00 right!

Another update went to the track with a small nitrous tune up. Made a couple suspension adjustments and played with the clutch a little and ran a 6.29 @ 110, the 60' is still way off from what I want/need. Made a big change and she went on the rear bumper, so I called it quits till I can get some double adjustable shocks. Not bad for the first time out.

What did it 60 foot on the 6.29 pass? With it going 110 to the 1/8 you should be able to make a low 6.20 high 6 teen pass at that mph if it 60's good. On the big pills expect that 5.9 or better it you can get it to run to the 330 without doing anything stupid.
 
1.42 60' / 4.07 330'.....I am working on the clutch set up also. On the 4th pass it dragged the bumper!!! Not good. It will 60' 1.27 / 28 and 330 in the 3.85 to 3.88 range. It was way safe on the tune, I could easily take 2 maybe 3 degrees of timing also.
