Hi, I am curious if anyone has dyno'ed their 60R? As with my other AWD vehicles you will see a pretty significant drivetrain loss in HP/Torque compared to the 300/295 Volvo lists. Just wondering how much to expect.

Remember, that is crank horse power and not rear wheel. There is a significant loss at the axle and with the transfer case and differential there is considerable more loss. The real test is whether your Volvo works for "you".

Right, I agree, having owned all-wheel-drive vehicles before I know that your wheel horsepower is considerably less after you take out all the mechanical "loss" stemming away from the crank. For instance, my old Sti was also 300hp at the crank but most would only dyno 235-240hp at the wheels meaning they lost almost 60-65hp from the friction of the mechanical components between the crank and the rubber. A rear or front wheel drive car would not see as much of a power loss as opposed to the AWD system.
I guess what I'm asking is does anyone know the percentage of loss I should expect in the S60R? Anyone dyno'ed their car and came up with 250, 270, 240, etc?

Just a follow up to this, I was reading on one of the aftermarket websites where someone had put a ecu flash and exhaust on their S60R. The good news is that it also showed a baseline dyno plot of the car before and the numbers were:

268.8 whp
264.6 ft/lbs torque


with the chip the car put down 316.6 whp and 302.3 ft/lbs.......not bad at all for less than 2K in investments.

I don't have any S60R.. Yet.. But this url may give you some answers.

cool....I'll check it out......I have found some stuff on the BSR chip 354hp...vs the stock 300
