LT1 Dyno Archive
Years ago, 94 Z28, 6 Speed, power everything, hardtop, full weight plus Kenny Brown Double Diamond Subframe Connectors and BMR STB.
Stock 106000 mile shortblock
Locally Ported Heads, stock valves, real mild, no milling or anything, Fel Pro Head Gaskets slightly thinner raised compression slightly
LT4 Hotcam & 1.6 RR's
Stock Intake Manifold w/ Front Opened to 58mm
Mac 1 5/8 Shortys & Offroad Y Pipe
Flowsmasher Catback w/ Cutout
Holley 58mm TB
K&N FIPK
LT4 KM
LS1 Aluminum DS
1LE Bellows
McLeod Dual Performance Clutch
3.73's
Lakewood LCA's & Panhard Rod
Nitto 245/50/16 DR's
Stock MAF
Stock Tune Running VERY RICH & stock rev limiter which was making me shift to fourth right at the line
Best 1/8 Mile:
8.00@89.63 MPH 1.97 60 FT, highest MPH 90.03
Dynoed it a week before the motor blew and it put down some really low numbers as I had been spraying it with an NX 150 Shot and it had two cracked pistons when I dynoed it, never got any real bottle passes at the track because it closed over the winter. I have no doubt that car could have ran quite a bit better on a real tire and tuned with the rev limiter out of the way. Probably could have MPH higher just getting the damn rev limiter out of the way.
Also did a 396 shortblock for it and a 355, bought a 12 bolt, Spohn Torque Arm, BMR Tubular K Member, more bolton stuff, bought some LE heads for the 355, never finished either, parted the car out.

Yah I went to the dyno finally today. Not to impressed but hey it was fun as hell. The numbers are 236 hp and 261tq at the wheels with a cai and open cutout. Without the cut out it was 225 hp 260 tq. Time for some more modding. I have a vid too that ill post up soon.

Dyno graph was completed with a broken e-cutout motor (stuck 1/8 open)
That cost me about 4RWHP and 9RWTQ based on previous runs.
