Thread: td5 on dyno

From memory it is a 3.9 litre, 4 cyl, cummins 4BT. Welderup posted his build thread on a 4BT (not 6BT) forum.

Correction to my previous post:
Def nitrous

Not 3.9 litre 4cyl, but 5.9 litre 6 cyl.

That twisted td5 is crazy...they have all the goodies.

I have the full gale force package on my 110 which is different to this as retains factory turbo as it was importeted from the UK. It makes such a difference as it is unlike any other landy I've ever driven it is just effortless but when u put your foot down it just keeps pulling away....

The issues everyone raises about ambient temp and fuel quality have not had any adverse effects in over 50000kms yet fingers crossed

Thanks Josh,
Great to hear some feedback from someone who has actually gone out and done it. Gives me a renewed confidence and optimism with these products. I’ll defiantly be revisiting their website with a more open mind next time.
Onward and upward.
Cheers

Your correct john welderup also have a 4bt twin turbo from what I can gather and its in another rat rod from memory but on the one discussed I asumed it was a 6cyl only by the number of injector rails...john do you recon the 4bt and 6bt are as strong as the 4bd1 etc etc?

There is a system out there..... this is cut and paste from the guy



i have tried it with a 50/50 blend of water and methanol and didnt really see a big power difference but the egt's went way down so it can get more diesel put into now


with just water the EGT sits on 590.. with methanol and water 480 holding it flat in top gear going up hill.


with the chip on and no water or anything the exhaust went up to 640 same test place power from the chip with custom tune is about 60% over standard but still need to do more tuning soon with the water injection

Those who push their 4/6BT's need to up the diameter of head studs to the stock dia of 4BD1 head bolts. When pushed further they also have kits to increase head studs even further.

They also increase the dia of main bearing cap bolts. When I ordered APR studs for my 4BD1T, I also wanted replacements for the mains but was told they don't make any that large (16mm dia) - so I assume 4/6BD's have smaller mains than that.

A 4BD1 will happily rev much higher than the 4BT.
