The main reason I enthused about giving it a few more ponies is that we own a daf 244, which is a 12t 4x4 truck, with a 6bt, 5spd box, and comparable tyres, and the 150bhp or whatever that kicks out is good enough for a leisurely amble to 45mph, and a top speed of about 55. If that's enough for you then so be it, but if you want to be able to cruise at nearly 60, then you might find that it'll take a week or so to get there. I appreciate that you'll have a bit higher gearing and less weight, but speaking from very direct and comparable experience, you'll find the extra torque available with a tweaked pump a proper bonus. The difference between going fast and not slowing down on hills is massive. If you're keeping the gearing the same, there's no reason to be afraid of extra oomph. The people stuck behind you will thank you, unless they're busy happily taking photos of the car, which is a possibility!

Also, is there an easy way to compare the number of brake actuations available from the hydroboost's accumulator against the number from your proposed air tanks? We whacked a sprung actuator on the REO handbrake, and that's saved our bacon more than once when catastrophic air leaks have happened! Would be even better if it wasn't actuating a '40's vintage drum hand brake...

Dangerous and I got a few hours on the 'little DAF' as it's now known. No. 1 Son was conspicuous by his absence this time due to a week's holiday where, as is his wont, he has gone Walkabout. I fear that he was less likely to be involved in an Aboriginal rite of passage and more an overlong stay in the in the Australian themed bar of the same name. First order of business was to get the engine mountings off the chassis. The gearbox mountings were reasonably bolted but the engine mountings just had to be rivetted Sabre saw, drill, angle grinder and cold chisel got us here Then Dangerous' humongous big hammer got them finally off. This was a pant-wetting moment as I'd pulled the air tank pressure relief dump valve and then cut the plastic air lines It was the wrong valve At the end of play this was our increased stash This is going to need some gentle jet washing Front end gutted Looking a bit gutted at the back as well. Next week we'll try to offer up the Cummins to the Goddess after we've worked out the the PAS pump removal.

Really enjoying this if those headlamps are as good as they look in the pictures then get them on eBay, they are obsolete from everywhere now and fit Fiat ducato motor homes as well as DAF 45's and can be worth as much as £150 each depending on how many people are selling the very limited amount of NOS there is left in the world now!

Keep it up loving the thread so far oh and can we see more of dangerous at work? hes obviously earned the name Regretfully Dangerous is the shy and retiring type. There is a reason for this and I shall share the full story of corporate evil as soon as it's safe to do so. Not only were the rivets a pain but every g0dd4mn bolt has a different sized nut on the other end. I think I wasted more time rooting through the toolboxes for different sized spanners than I did working. At one point I may have been heard to cry 'An air chisel, an air chisel, my kingdom for an air chisel!'. Had an instructive conversation with the underwriter at my specialist insurance company over my 'modifications'. The engine swap was not a problem after the long explanation of very little extra power (20 bhp) but likely to have a lower top speed due to the rev limiter. The interesting part was about upgrading the brakes, whether hydroboost or air over hydraulic and their advice was don't mess with a classic truck's brakes. It's not that they can't be improved but better brakes means more likelihood of 'more aggressive' driving (their words, not mine) and should there be an accident the authorities would concentrate on the effectiveness or over-effectiveness of the brake modifications. So there you have it, poor brakes make for better, more considerate drivers. Exhaust brake here we come. We're trying to work out where to put the diesel tank so we can use the old petrol tank for refuelling the 15 gallons per hour, at idle or full chat, it doesn't matter, SpridJET (copyright Mr. Vulgalour of this parish) so if you think that Traffic are humourless automatons then you've never met VOSA at the roadside. I'm really looking forward to the conversation over two tanks of fuel on-board, one diesel and one JET-A1 AKA Kerosene or 28 sec heating oil. Let them test the fuel going through the engine all they want

Phil, This is diamond info and I acknowledge the social convention that I owe you a large alcoholic beverage of your choice when we meet up. A few hundred quid will make a lot of difference to the "Scrap A DAF and get a free Cummins & box" fund. Cheers, Ian

Hmmm...........try telling that to the distraught mother who's kiddie you just ran over cos your truck would not stop in time. Fit better brakes. No excuse not to do so. Just my opinion.

That would be my position too. I'd prefer to pay a higher insurance premium, and have better brakes, than save money and not. I can also envisage a post crash conversation along the lines of: "Hmmm Mr. Anderson, you fitted an engine with more power, what improvements did you make to the brakes? Nothing? Why's that? To save aggro getting it insured you say? Come and sit in this nice room with bars on the windows for a bit..."

Another scenario : "So Mr. Frankenhealey, you upgraded your brakes and instead of slowing in a controlled way, you locked your wheels and slid off the road onto the pavement into a group of children. Come and sit in this nice room with bars on the windows for a bit..." Heads I don't win and tails I lose. So standard reconditioned brakes with additional exhaust brake and conduct it like 'Driving Miss Daisy'.

If driven sensibly and within the means of the vehicle, I don't see the extra power causing you too much grief. I would stick with putting an exhaust brake on to help and if possible see if you can get more modern pad materials fitted which may help you stop better.
On a side note could you fit a retarder to the propshaft like on a bus which helps slow them down rapidly when the throttle is shut, I think it works via using magnetics but I could be wrong

Hope I did not sound harsh. Its your call, it depends on what the original brakes are like I guess? But if the DAF weighs the same I don't see why the brakes should be over good on yours but safe on the DAF?

Playing devils advocate .......
There is an 'incident', and i am one of the agencies tasked with looking at your 'truck' .... I see that the rear body has been radically altered from original design, the engine has been changed, slightly more bhp,but i guess much more torque as well and you haven't done anything to the braking system? What other safety related issues have you skipped? You tell me your insurers have told you not to touch the brakes, i would ask what qualifies the insurer to make such a statement,and whether they had an engineer look it over to ascertain whether this is the case.
................................................
I drive an HGV ... So i know all about Vosa, and how they 'see' things.
Personally i'd look at using the Daf brakes along with exhaust brake, better to have it and not need it,rather than need it and not have it!

It's your call. Like I said earlier in the thread, Bedford MKs and MJs basically have the same drums and shoes as your RL, but they're air-over-hydraulic boosted, rather than vacuum boosted. You're not making them "better" at stopping you, the drums and shoes are unchanged; you're lightening the effort needed at the pedal and adding more control.

Contact patch and suspension and tyre technology, centre of gravity, also talking Vented discs vs Drums.

The tyres will probably be the deciding factor, I know it's running on better ones than the standard fit but even so they aren't up to the standards of modern tyres by any means.
I had a Land Rover on bargrips and it was terrifying in the wet!
For all that- personally I'd still go the same route as Glen is planning myself, especially since that effectively replicates the production TK/MK setup.

Weird your insurance saying that, mine said the opposite with both my Capri and landy when I upped the ponies. The Capri lot were quite emphatic about it, basically said if I didn't up the brakes to a similar spec to the engine-donor's, they wouldn't touch it! But then, I've never noticed a lot of consistency between insurers...

Vintage trucks are also a lump different to cars, I see were they are coming from with the brakes and I also feel the general consensus on here regarding such a subject, I just hope its not going to end up like certain Lotus thread and wheels.....
