Looking for info about Key Power

Hi,

If you have no luck getting hold of anyne who knows about your engines from KP you should be able to work out what most of the work done was if you have the engines and the parts used are still on them.

You could find out what Injectors it now has compared to standard, measure the height of a few before pulling any out in case they have an off spec timing height. The turbos and nozzles if used should have casting numbers on them. A lot of the other bits a such as coolers etc should also have someway of identifying their origins as well.

I'm pretty sure they're still around. Check under either Key power or Goldcoast power, I thought I saw an ad for them selling a set of engines not that long ago somewhere.

Key Power was once the Miami Detroit dealer.
The owner, Duane House, got out of the diesel business many (15? 20?) years ago and into the 'Learn How To Drive Semis' business.

The old location has been known as Florida Detroit Diesel Allison and has an office closer to you in Panama City.

Here is a link to Goldcoast Power. Hope this helps,

54 Bertram, keep in mind that the 'specs sticker' mounted to your rocker box covers adds a small wealth of info such as turbo model, timing, injector size, and a dozen more items.

You mention "updating".

The 1981 12V71 pre-54 was a 675 HP motor.
The advent of the 54 in late 1981 gave rise to the KP-modified [BK 800] 800 HP (820 BHP) version driving a Twin Disc CHP 1.5:1 gear.

By the mid-eighties, they upped that to the 900 HP version (915 BHP) equipped with a ZF 195 tranny. $685K for that flavor of 54 Bertram.

Have you tried contacting FDDA Miami for the spec on your serial numbers?

Here's a thought: do you have any independent Detroit guys in the area?
Gee, New Orleans, probably a few dozen. Call around to thems who've been around since 1980 and talk to one of the geezers who know what a BK 800 12V-71TI is; he might just be familiar.

Lots of guys who did rebuilds when yours was done hotted up their motors with at least fatter injectors and monkeyed with the rack & timing.

Hint: 800s ran 28 X 32 cupped wheels, while the 900s ran 29 X 33 cups.

If it's the 900 version it should have 9215 Injectors I believe. You can not go by the build list on this engine. It requires J6 valves, wide gap rings, a bigger turbo, and a different intercooler set up. ( low profile). Also has a low profile heat exchanger set up.
These things where hopped up by Key Power from the original build at Detroit.
I normally set the injectors at 1.496 for these to run good with a standard modulator setting of .454

(I have built more than 1 or 2 of these over the years.

I'm one of those old geezers and I don't know what a "BK" is.

FYI:

"BK" = Bertram Key Power. Those early 12V-71s were built up solely by Key Power for only the Bertram 54.

This was back in the day prior to Roger Penske's homogenization of marine applications at the factory level circa 1986/1987 and wherein DD distributors marinized as they saw fit.
