Attn Mack drivers or ex.

In the old days (r model and such) there was the econodyne, maxidyne, coolpower and thermodyne. What horsepower were they ?
Cheers,

econodyne was the engine family introduced IIRC in the late 80's

IIRC maxidyne was a engine family, originally 237HP, with various upgrades, IIRC 300, 325 and 350HP depending on the setup, and IIRC was an evoloution of the thermodyne

coolpower was a setup that to my understanding was basically forced intercooling

thermodyne IIRC was the first generation of OHV diesel engines that mack produced

sorry if i'm a lil vague, but its been more than a couple of years since i had anything to do with a Mack

Thermo was 237hp, not big in the horse depatment but tons of torque....... well for it's day. Coolpower I believe was 280hp; maxi-320hp and econodyne 250hp. I was never a Mack man so don't go down the pub taking bets on this reply.
Don't forget the Perkodyne at 120ish hp

Lucky you

tell me about it....... try getting the call out to sort out a siezed front wheel bearing at 9pm...... had the replacement stub/hub off a donor truck off by 11pm, had the replacement hub/stub on and the truck rolling by 3am.....

and people wonder why i drive a desk now..... TA'ing for electricians, boilermakers, diesel fitters drove me round the bend!

that said, first time behind the wheel in a truck was in a '81 R model with a 350 and 12 speed, mostly paddock/yard work

last time was a 1984 superliner, 400HP V8 and 12 speed with a 80 tonne float..... very naughty of me to have driven it, but the fitter i was with couldnt understand the air shifter......

Last Mack I drove was pulling three fuel barrels in WA, Cat 550, RR 18 (auto) Apart from the office a fair jigger.
I drove a Superliner on heavy haulage a few years back that was impossible to drive in the rain. It used to steer from the drive, not camel back....air . I eventually blew a front diff, it was then discovered the factory had fitted two different ratios.
Make Another Choice Kenworth

the supreliner i mentioned used to be good for converting axles into pretzels...... couldnt figure out why untill we watched bad loading of the float and horrendous drivers (ever seen a truck pull the front wheels a couple of feet off the ground trying to move a D10/11?

i felt sorry for the poor thing, not even a volvo deserved that treatment

i've allways had a thng for the bulldog breed, after all, they're not held together with pop rivets and zipties like kenworths!

[V8Ian]

I'm looking at new ones now, down to Western Star or Volvo. A few years ago it would have been between 4900 or 6900, but now I'm no longer driving myself, the Volvo is looking far more attractive

something is wrong here....... i'm 27, and i'd prefer a series 1 superliner with the big gun V8 or a W model to anything from the last 20 years..... :-S
