For You 60 Series Guys Hp Changes

[robertglines1]

thanks: the information lets me know where I'm at.  As I get older have lost my need for only the best;still simple hp/performance increase is always attractive. I've never driven a bus with a 4 stroke(I bought my bus without engine) or a 10 Spd Eaton autoshift  so don't know how it will preform. Present set up is 400 hp 8V92 with 5 spd Allison. Any comments on how much difference to expect with the 430/470 hp & Eaton set up. Biggest hope is to go from 5mpg to 7 or 8.    Bob

I get about 10 m/Cnd gallon, 8.34 m/US gallon with the hockey team's bus: 1995 S60, (pre EGR), 12.7 L, 7 speed Eaton-Fuller, (manual).

You will find driving the S60 a lot different than the 8-92. Very torquey from 1200 to 1800 rpm. You have to get used to shifting it within that range, rather than on the governor with the 2 stroke. Cruises at 1500 rpm at 70 mph. Doesn't slow down up the hills.

S60 just plainly has effortless power.  You'll quickly forget hills and questioning if the bus will get to the top.  Amazing what torque will do for pulling power.  You should get towards 10mpg with that setup.  But-don't expect Allison acceleration from the stop light.  Autoshifts are slow and ponerous up to 40mph-then it starts to perform pretty well.  One of the reasons they get better fuel mileage. Good Luck, TomC

Folks,

Do any of you have Brake Specific Fuel Consumption (BSFC) figures for the 8V92 that they you can share?
