Engine dyno vs chassis dyno

[1wild&crazyguy]

I'm having my 410 dyno'd when it go's back together.

This way when/if it doesn't run the #'s I know what not to look into.

After that, the chassis dyno to see how much is being eaten up, and a lil tuning.

And we have a winner! :cheers:

If you don't know what you start with, how can the chassis numbers mean anything or what type of drivetrain loss you incur.... Hmmmmm...

i read in the new mopar muscle that the camquest 6 is pretty close to what they really got on the engine dyno..this one http://www.speedwaybids.com/tech/ezonlinedyno.html shows supposed times and wheel hp was told its pretty close as well.

Chassis, I always figure I drive and race the car not just the motor. But you have to know what you are looking at sometimes. Go to a really loose converter and watch the numbers go down on the dyno but the car goea faster. Just my 2 cents.

they both have there places,engine dyno of use break in and changes engine, chassis dyno for rear wheel hp shift points

Engine dyno first than test and tune. Its alot easier to change jets and timing on the enging dyno. Engine dyno is also a good place to find any leaks before you have stuff in the way.

I voted chassis because I'd rather know what I was putting to the wheels (I can confirm where my chassis deficiencies are from my actual 1/4 mile times)..

Chassis dyno for me. I put my car on chassis dyno last year, in 30 minutes picked up 40 HP. The adjustments were made to my Ignition box, and fuel pressure regulator. Would have taken all day at the track for same accomplishment. Also, unless you use the same ignition box and fuel pump and regulator off your car on the engine dyno, these issues would not have been seen. Most engine dynos have their own box and fuel pumps/regs. Granted, chassis dyno numbers are not as "Radical", but those are the numbers pushing you down the track.
Both are good tools.
