Big ol Burban

[Addicting]

Well to everyone following , the burb just got off the Dyno. Curious to know what HP and TQ you think it made to the rear wheels.

I will post the graph later today after you get done guessing.

A stock LS2 truck engine at the crank makes 395 HP and 400 ft/lbs.

Mine has ported heads, a slightly bigger cam, and long tube headers.

On a rear wheel dyno the parasitic loss is 30-40% depending on tire size, gears, and weight.

315/335 at the wheels.

A 1999 Chevrolet Suburban with a 454 engine produces 290 horsepower and 410 lb-ft of torque at the crank.

Apparently a hunting forum isn’t as geeked out about HP as I am. Dave was close, it has 321hp at 5500 rpms and 318 ft/lbs at 4700 rpms. Remember that is at the pavement not at the crank.

I've enjoyed this thread , but the HP seemed like a trick question , so I passed . I am impressed with the finished product , good job !

I wish it was done. Still getting it ready for a road trip to Florida at the end of the month. Got a handful of shake down issues to tidy up yet. I had to order a good battery for the main. Decided to try an Odyssey extreme as the winch will run off it as well. Trying to find an exhaust that doesn’t have a drone is a problem. I ordered a stock style one to try, albeit it was made to fit a ford. I also have to replace the starter with a mini and heat wrap. The factory one can’t handle the heat sink from the headers.

Finally, I have to have the trans programming redone better. It slams into gear and I am not a fan.

Still impressive stuff . There will always be something that needs to be addressed or changed , or improved .
