I would be quite pleased if I could obtain even that modest figure. I don't want a race car from it; I have a Triumph GT6 electric vehicle conversion in progress for that...
Even getting to only 170-180 horsepower would satisfy my wants for this Mercedes.

You also talked about bio-diesel or SVO conversion. This will reduce the power of the engine not enhance it.

While usually true(I've seen also dyno results showing small gains from SVO/WVO on some cars, but I expect a 10% or so decrease in power on mine), the purpose of that mod isn't performance. The reasons are for saving money and reducing environmental impact.

I'd be quite pleased with 'a little'. 0-60 mph ~9 seconds would be satisfactory, but if better can be obtained without costing more than $3-4k or compromising reliability, I will definately consider it.

I wish mine were compatible with a rocketchip. A E300D will see significant gains with one, allowing perhaps 0-60 mph in 7 seconds. I wasn't able to find one near me though, and at the time, only had a bicycle as viable transportation; the SDL was close and available.
Does anyone here have experience running an older diesel with straight-pipe exhaust, and if so, what power gains can be expected? With me running WVO in this, emissions and environmental impact wouldn't be much of a worry.
Thanks for your answers. I did more searching on these forums and didn't find much; I can't help but wonder how those individuals from Finland got 300+ bhp out of these.
