Thread: 300 tdi performance

Diesel Gas? I had my 300tdi pump tweaked and dynoed and that was pretty good for couple of years, but after getting dgas it keeps pulling easily up to 120, but thats as far as I take my tractor haha

No not diesel gas, but before the tune up it would get to 120 with a little urging!

Thanks

G/Day Guys, A 130 Tdi Deefer with the 300, Stock standard should have no probs winding the speedo up to the stopper on a slight downhill run !....Mine Will...LOL


Cheers Sumo

Maybe go a larger exhaust, your pushing more into the engine it has to get out somewhere

I found after fitting a 3 inch I can wind mine right out to 100 in 4th

4th ?
I've hit 100km/h in 3rd

During the 'tune' were the valve clearances adjusted?? This does slow them down a LOT if they aren't right.

My question is can you have low end performance and also at the top, I was out done by a FESA 130 tdi and figured mine is lighter and should at least keep up???? is there an answer?

A Defender does push a lot of air and the drag increases exponentially with speed, it's a logarithmic scale.
As BlackKnight calls them, "the shed on wheels"

Of course being burned off by another Tdi Defender is a bit dispiriting.

Surely you would check the loud pedal is operating the injector pump to the max stop. Has it been adjusted? You should be able to see 4000 rpm before the governor hits.
