1993 DB2 Dyno run with ATT

[WarWagon]

1993 DB2 Dyno run with ATT, 108 degrees Fahrenheit out. The fan running made a difference with some runs having the same peak back to back numbers. This was a 'sane' run with the smoke completely clearing and EGT at 1000 MAX. Room to turn up the fuel. Boost was 14-15 PSI. It will generate more with a trailer and cooler weather peaking at 18.

Hard to hold Patch on the rollers even with a blown 455 HO Pontiac big block in the back. Did a scrap metal drop off after this pull.




Dennis paid for this run.

Would like a 2nd opinion on the numbers before I post them. Dynojet software and files can be sent.

Best I could tell in 3rd gear, direct, with the TCC locked was 350 TQ and 175 HP. It hit 213 HP and 629 TQ peak with 1st gear and a balloon after a shift due to the torque converter. It is rough to read through an auto trans. I did several 62 MPH stomps to 85 MPH the range of 3rd gear. Along with 0-85 and 0-105 runs redlining as the DB2 shut down fuel after 3500 RPM.

These get noisy! :rolleyes5: You have been warned.

I agree with 3500GMC, that color scheme is sweet.

Fixed 2nd vid.

Yes I too think the color is awesome! Njce truck War Wagon. How much does a dyno run cost?

 

[WarWagon]

Cost to dyno is $65.00 an hour. Track is $10 a night on some Fridays.

Looking at the graph do you see where the TQ is higher with the TCC override switch off? Also look at how much more TQ I get when running 4th all the way out vs. 3rd that ends around 80 MPH at 3500 RPM because the DB2 hits the governor and closes the fuel metering valve. I have to read the numbers after the peaks caused by the Torque Converter slowing down the engine after a shift and then locking back up. Shifting 3-4 with the TCC override switch on is a hard shift and doesn't balloon as much.

Torque Peak.

Wow thats not bad for a evenings entertainment n play with the truck. Figured it would be way up there in cost!

 

[buddy]

The dyno runs are done with tranny in 1:1 and locked torque converter so the transmission isnt multiplying the engine output. When not locked up the engine can rev really high, but the tires are spinning slower with more force, so its deceptive, the tranny is causing the torque increase. When on OD the tranny is spinning faster than the engine, so at high speed it will seem like it hold on longer with lower RPM at given speed.

You're truck sounds and looks nice, very little smoke.

@WarWagon videos on private again.
Takin a trip down memory lane…
Can you add your “asthma attack” article to your signature line? I love going back to that at times.
