I don't know why you'll want the popcorn Dougal,your the one with lots to say about LPG/diesel even though you've never had it fitted. Pat

Been talking to MTQ turbo guys, they recommend a complete new GT25, straight bolt on, big exhaust, big cooler, pump tuning, oil cooler, and no water meth. I guess i will still retain reliability....

Could just do a TD5 and chip that and have more power/torque right there.

For monster torque go the Isuzu.

Plans for the driveline are heavy duty axels front/rear, disco 2 DC joints, stock torque converter (they are up to the challenge) heavy duty valve body assembly, trans temp guage, 28 x 28 trans cooler.

Suspension will be king springs 3", tough dog big bore shocks, rear trailing arms, front/rear arb lockers on 33" MTZ's

Warn winch, winch bar, rock sliders and custom tail bar. Hopefully this all goes to plan.

The GT25 is a range of turbos. Did they say which one?

Dougal,

it was a serious question. What are your thoughts??

have you nay experience with adding alcohol to the fuel?

No I haven't done it.
Anything which burns and is fed into the intake of a diesel can cause detonation, just like starting fluids. This is why I haven't done it and won't be doing it to any of my engines.
Even diesel in the intake is a silly idea.

If you'd like to donate an engine, I'll give it a shot.:angel:

Water/meth gets a lot of press in the UK where people use it to try and get more power from computer controlled diesels, it must feel better than paying for a remapped ECU.
They use the water to try and suppress the detonation, too much methanol in the mix and they can hear it detonating apparently. Exactly the same behaviour as lpg fumigation and exactly the same response by the tuners, they water down the methanol until they can't hear it.

Water by itself does very little, it's hard to evaporate enough water to make a difference. If you inject water upstream of the turbo then the water droplets damage the compressor wheel. Downstream of the turbo the increased pressure makes it harder still to evaporate. They call it an alternative to intercooling, but the cooling effect is small, it doesn't compare to intercooling but it's easier so people try it.
If you're running a sled pulling tractor it might be fine, especially depending on the rules. But for a street driven vehicle it doesn't make any sense.

sorry mate, im a bit confused?

did you cover LPG or Alcohol or both?

there seems to be plenty of companies world wide doing LPG, from the transport industry to racing diesels.

Adding alcohol into the diesel(fuel tank) was something i heard from Dr Karl K

Serg

Serg, there was a big, err 'discussion' on LPG fumigation a a while back.
Dougal stated his case pretty firmly at the time :D

I'll dig it up and you can have a read.
