Is this about right for nitrous?
Took my 70 Judge to the track ran a best time of 13.91/97mph. Dropped a 125 shot of nitrous and ran a 12.59/108mph and then a 12.44/110mph. That's a decrease of 1.47 seconds. Is that a lot or about right? No traction problems and 60 ft went down each time.

Sounds about right, what were your 60's?

On motor 1.98 and 1.96 and nitrous runs 1.97 and 1.89. I was a little gun shy on the first one as I had never run nitrous and it was first time out on a new torque convertor and rear end. I ran the motor up on the brake a lot harder on the 1.89 60 ft. Was getting 2.1 to 2.2 before the upgrades.

How soon were you able to hit the nitrous?
That's a very nice pickup, congrats! |

It's activated at full throttle with a switch on the carb. Plugs looked good at the end of the run, not too lean or rich. I need more seat time with the new torque convertor. This is the second time I ever raced this car and the first time I have ever used nitrous. I did get the last and best run with a .065 RT. I'm just getting my feet wet on drag racing. I have to say that I really like the ET street radials. They are giving me great traction. I also like the Redneck Tight 3000 convertor. It dropped my 60 fts by .2. I didn't look at RPM's at the traps though, somehwere over my shift light set at 5600.

Goatdr...I see you really like your redneck 3000. Thats the converter I have and I really like mine also. I wasnt really wasnt sure how it was going to work out...but mine seems to run really good.

It's a .030 over 400 with 70 #13 heads and flat tops. Should be 10-10.5:1 compression. I'm currently running a CarterAFB 750 and the plugs(R43S) look good, but looking to upgrade it to a better carb(Cliff Q-jet or modified Holley 750). I have a Carter mechanical street pump, but have an electric pump that I plan on hooking up this week. I'll probably add it to the mechnical and activate it with the nitrous switch. I think my top end speed is a little low. I also have a new XE274 that's going in this winter. I'm just trying to get it running and get everything fixed. I put new coated Flowtech headers on, fixed the 4:10 posi, changed torque convertors, upgraded springs to Comp 995's, upgraded HEI module to MSD module with rev limiter and added a 125 shot plate.
