Went to the dyno today to see what the stand is making on the bottle, lets just say that it leaves some to be desired. any way the first two pulls are N/A

pull 1 14* timing
rwhp 264
rwtq 303
a/f 14.5:1

Pull 2 14* timing and +2# fuel press.
rwhp 269
rwtq 304
a/f 13.5:1

Pull 3 10* timing and 100 shot
rwhp 331
rwtq 400
a/f 11.8:1 to 12.5:1

Somewhere along the line the motor is eating 40hp of my nitrous, cant figure it out. Oh well scrapping this motor next two weeks and dropping in a built out tha arse 306 ready to ingest lots of nitrous.

#1 Isnt the "shot rating" based on intial HP?

#2 Are those ratings that accurate?

#3 That stuff really brings up the tq, huh?

Anyway, like said above...take it out on the street!

yeah man...got 100 torque outta it. i never really thought that a 75 shot of nitrous actually gave you 75hp and 150 and so on. i always thought it was around 2/3 - 3/4 of what it says. just what i was told tho

I think the shot is for flywheel HP. Anyway I don't think it could be totally accurate. Also what kit do you have?

NOS dry kit.

On the completely stock motor with the same kit it made an increase of 98rwhp and 160 rwtq.

As for the motor numbers being low, the rings in this motor did not seat so it has major blowby issues, I have to ziptie the dip stick in the tube at teh moment. That is the main reason the motor is comming back out in a couple weeks.

For comparison sake I got 86rwhp/125rwtq gain with an NOS dry "100hp" jetting, which equated to a 9/10's ET improvement and 9 mile an hour trap speed gain...

I went up to a 175 shot but haven't tried it on the dyno or the track yet.
But it sure is fun on the street.

This gave me the above numbers and a average 12.1:1 air fuel ratio with a very safe (and rich) 11.5:1 air fuel ratio from 4000 to 6000 rpm's...

What jets are you running at that kit, and what fuel pressure? I have had very good luck with my NOS dry kit.
