Cummins Drift Truck a la Dum-Dum

[Dum-Dum]

Hows the length of the engine looking with the engine bay?


wondered recently how good the 4bt would be, probably a good chunk lighter, iirc the 6bt is 450 kg!!  nearly 4 xud's

4bt isn't as common ive been told, not so sure on that, probably dont come up as often as they're usually found in smaller buses of which theres thousands of dennis darts about!

Weight isn't particularly an issue, the truck is a hefty old beast in the first place.
Length is an interesting conundrum, I've read in some places that they are a little over 1m long which my engine bay isn't but then a land rover bay is shorter and a few people have them in land rovers.

I was thinking the same when I opened the thread but I'm guessing it won't have the same appeal to Chris.

Also, this is amazing.

Not interested in the 4bt. Ain't no substitute for cubes!

Plenty of 4bt conversions about....however to me somewhat defeats the point, 80% of the reason the 6bt is such a great motor is because it's 6 cylinder, sounds absolutely musical when it's on song, no four cylinder will ever do this....seems like alot of effort to me for just "another four cylinder" with the 4bt....

And Chris, please start it on 24v, it's the best way I promise :p it's huge ampage to  roll these motors over on 12v....

Agreed on the 6 over the 4.


If you use the watts/volts x amps Triangle you can work it out
The 24v starter is 4kw 4000/24 = 167amps. If I had a 12v 4kw starter built it would need 333amps which considering a decent battery has 540amps starting power it should cause no issue

Hahaha good man, about time you started playing with dervs again. You better not get bored of this half-way through, however, when you do Jonny and I will probably buy it.

I knew you 2 would love it. I think once the engine is in and running that'll be every bit of motivation I need to finish the rest.

best of luck with it dum dum, and I hope it all goes well for you.  I hope you see this right the way through to the end, so you can enjoy it!

Cheers mate

About time we had another cummins on the forum.

Derv for the win

Yes it is about time, wanted one for so long and now I have the opportunity, motive and means so it's gotta be done.
