Well guys,
Dynoed my LT-1 6spd this past weekend. Here's the specs:
'94 Corvette LT-1 ZF 6spd
Cut lid
K&N Filter
Taylor 8.5mm wires
MSD 6A Ignition box
NGK TR5 Plugs gapped @ 0.035
B&B TriFlo 3" stainless exhuast
Compucar "Bag Kit" Nitrous system (this is a dry kit sprayed before the MAF, currently using a 0.076 jet)
Other than that, the motor internally is stock.
Best 1/4 mile times to date:
Motor
60ft 1.954
330 5.731
1/8 8.725
MPH 82.50
1000 11.292
1/4 13.41
MPH 106.96
Nitrous
60ft 2.006
330 ????
1/8 8.150
MPH 91.11
1000 ????
1/4 12.42
MPH 117.01
Now on to the dyno #'s.
On motor the car made 253.8rwhp and 295.2ft-lbs of torque at the wheels.
On the bottle the car made 370rwhp and 461.4ft-lbs of torque at the wheels.
Thoughts? Opinions? Comments? Questions?

Re: Dyno Results (Hi-psi)
Cool... let me enter those into my top secret program and see if they match. :smash:
Well, Im kind of curious what happened between the 60' and 330' mark. I ran my vette a couple weeks ago and being new to launching standards at the track on street tires I got..
60' ----- 2.170
330' --- 5.799
You had me .21 tenths of a second to 60' but our 330's are close :eek:
A 1.96 60' time and almost 107 MPH should be more like 13.07s

Re: Dyno Results (Hi-psi)
Yes but his mph is about right or even a bit on the high side so it may be the difference in dyno's for the low readings.

Re: Dyno Results (red90sixspeed)
Here's the charts.
I made a motor run and two on the bottle. On the first chart is the motor run. It seems like something is happening about 3900rpm. Weak Opti maybe? However it seemed to have smoothed out on the bottle. Maybe the A/F ratio was bouncing around in the upper RPMS under light load on motor,....then when the fuel system is running more to 100% on the bottle it smooths out? On the nitrous run on the first graph the break in the curve is clutch slippage. I hit the bottle at about 3200rpm and the clutch wouldn't hold the torque spike. As far as I know this car has a stock clutch and I have no idea how many miles on the clutch. On the second graph is just a nitrous run. I waited until about 3500 to spray it and the clutch held. I would bet money however that if I could get the clutch to hold closer to 3000rpm that I could see very close to 500ft-lbs b/c on the pull where it slipped the torque was on the way down when it grabbed. Oh well. Let me know what you think.
