New PB on nitrous tonight
New PB on nitrous tonight i got a chance to go to the track with some friends today. went the other week and ran a new pb on motor. mods
slp lid, ported tb, ls6 intake, 232/234 110+3 cam, long tubes, and 3.90's. dynos at 390/360
60ft 1.690
330 4.946
1/8 7.658
mph 90.20
1000 9.973
1/4 11.927
mph 115.64
my nitrous kit is a hsw dry plate. jetted at 150. on the same dyno it picks up 110hp/140tq.......still wonder why it dont make 150hp.......
1st pass i did a sissy 2k launch and went 11.7 @ 125.2 with a 1.94 60ft
2nd pass more of a launch but still alot of wheel spin. 11.42 @ 126.36 with a 1.818 60ft. that was my best mph ever.
3rd pass i for got to turn the nitrous on, but i did 1/2 track and still went 122
4th pass. mabye around a 4k launch.
11.283 @ 125.32 with a 1.645 60ft.
5th pass spun and went 11.461 @ 125.26 1.841 60ft
all in all im happy. i would have liked to get in the 10s, and get a few more mph out of it.
any one have an idea where the other 40hp could be? the cam is a 232/234 on a 110. so its got 13* overlap......

Hmm, easy 10s if you could get the 60ft down just a little bit more...
Last time I talked to HSW, they said their kits were RHWP rated...
bad6as, what jet size are you using?

I agree that dual .044s should make more power.
Starting from the top we need to check all the parameters the system is operating under.
1) Bottle Pressure....start and end of run
2) Fuel Pressure...does it stay constant
3) A/F Ratio....and how consistant across the RPM range
4) Timing....NA and Nitrous
Now to help with understanding the pwer the car is making.....I need to know a little about the car.
NA power
Trans/stall/clutch/gear
Tire you dyno'd on
Type of Dyno

Its possible the only issue is the Mustang dyno...they typically read lower.
You might try adjusting the timing a little and see what it does. I would start by pulling a littl mor, and see what the HP or MPH does. You can also watch the plugs for signs of pre-ignition and add timing back in if the car loses power by pulling timing out.
Here is a link to plug reading.
