Well guys i just got back from the track i ran ok this time. There was a 5.0 mustang out there running a 75 shot that was running only 1 tenth faster than me and he was leaving on slicks and pressing the button as soon as he left the line. The funny thing is we were running about the same times. So my question is does nitrious really help that much or does ford just suck. I am reconsidering how bad nitrious can be on your engine since i made more power with the stock heads and cam than that mustang made with the button and full exhaust. What do you guys think?

Its quite possible that his motor is fired form using that button too often. Then the nitrous would be just getting his car back to the hp it should have if the engine wasn't thrashed.

It really depends how fast the car is on the motor. If the car runs mid 14's, it will only run mid 13's with a 75hp shot.

If you put a 150hp shot on your car, it will run at least low 12's, adding another 15mph to your trap speed.

Like any other sort of mod for your car, nitrous gains will also depend on other features the drivetrain already has. If you add nitrous to a bone stock car, you won't get nearly the gains that you would if you added the same nitrous system to a motor which already has a better flowing set of heads, decent cam, headers and more. Many people who add nitrous to their cars fail to realize that to get the maximum benefit from the laughing gas, the motor needs to be optimized for it. Correct cam, heads, etc. They just stick the juice onto a stock motor, and say "Look! I gained 75 horses!" In reality, adding a 75 horse shot to a stock motor won't gain you 75 horses. If you add that to a modded motor, you'll get all 75.

In other words, don't be surprised if you can keep up with a motor where the ONLY change is to add a (relatively small) nitrous shot.

 

From what I have seen on the 75 shot, most of the cars it was used on get like 50 out of it. Not much. And why is he hitting it right off the line? Sounds like a bad time to me.

 

Absolutely not! Nitrous works best with stock or mildly modified motors, this I have seen personally and heard the same from Compucar and NOS. I had a 50 shot in my Camaro when it had a stock 350, giving me 5.5mph and taking 6 tenths off. My friend's 1989 L98 IROC picked up 10mph with a 100hp shot. The moded 350 in my Camaro now only picks up 12-13mph with a 150hp shot, a 2-3 mph loss.

Nitrous helps even more with low gears (2.73 or 3.08) than 3.42's or 3.73's because it gives you so much torque everywhere that it can't put it to the ground. A car with 2.73's and a stock converter has a better chance of hooking up off the line than a car with 3.73's and a 2500rpm converter... ditto with the nitrous.

he was droping the cluch and hitting the button at the same time on slicks but he just did not have the pull on the big end. So you guys think if i kept the 3.23's in my car got some slicks and a 3000 stall converter and a 100 shot and launched on the nitrious that i could run some awesome times. I saw a guy with a pretty much stock ls1 doing this with a 150 shot and he was pulling 12.0's he runs 4 tenths faster than me off the bottle.

So what did you run,...uncorrected????? and what is your best uncorrected? nitrous will react differntly depending on how fast the car already is.

uncorected last friday i pulled a 14.31 @ 96.8 the calculated air density was 5900 ft. The temp was 86 and the pressure was 27.49 the humidity was arround 40% @ 3500 ft elevation I rolled a 2.03 60 foot on that pass too. my best uncorected run on g-tech is 13.23 @ 109 but that was at sea level. my g-tech is a little fast it is consistantly 2 to 3 tenths fast as i have tested at the track. The mph on it is about 5 too high. I say a brand new GT mustang run a 15.5 too and he did not spinn and he shifted pretty good.
