Thread: My county is better than your puma

Dyno runs don't mean much.
What has he done to his 300tdi to get 200hp and how much boost is he running?

Your mates 300tdi puts down 120hp max?
My 4BD1T puts down 100hp at 2000rpm at 1000m altitude. So past 2400rpm I'm still winning.
BTW, mine doesn't even have an intercooler.

hey justinc! yeah i also drive a 200tdi , dads 300tdi , our county (isuzu) and used to drive pops series 3 stage 1 (3.5v8) and i would hav to say the 300tdi wins hands down although the 300tdi does hav a few tweaks that help it leave most other 4x4's on the road behind out of all of them i must say the isuzu has been the most trusty car out of all (dont know about the 300tdi yet but time will tell) but as for the 4bd1T i am just optimistic about all the who hars about it thats all
if the dyno is not that great wat is? considering they take into account a variety of things including all engine temps,wind speeds,tyres,weight etc etc etc
saying about the 750c temps that can be pushed out of a 4bd1T (which if kept at these temps for a period of time will almost definitely cause fatigue,hot spots or melt pistons or rings etc etc) wat about tweaking a 300tdi or 2.8tdi to these temps from there usual around 450-500c temps to the 750c they might go just as good?

i think he might be running 18-19psi with other things helping performance.....

WHAT? in another thead all you could screem was where are the dyno charts !!!!!

Just realised you're 18.

18-19psi cannot and will never deliver 200hp on a 2.5l diesel. He is spouting bs.
You can tweak a dyno to deliver whatever numbers you want. However the shape of the curve is the big giveaway.

I'd like to see the figures on a 200hp 300tdi

I see about 550 upstream and still have way enough torque for my uses I used to have it around 650 but that is clutch destroying territory, and ate 2 auto boxes also....I reckon that turboing and intercooling mine running 15psi has almost doubled the torque of a standard 4BD1
I haven't dynoed it at all as there is way too many variable numbers from different dynos etc. Still, may do it one day for a look see

All I can say is it is a quantum leap from NA, even in mild tune/ fuelling.

I've resisted getting involved, oh well......

In my 300Tdi I'm running 17psi, 3" dump and exhaust, the pump has been timed correctly, runs trick synthetic oil and fueled so that I can easily exceed 720*C and has seen the wrong side of 750* a couple of times with a 6mm probe so God only knows what the actual figure is..

......and it isn't that quick.....

A six cylinder Land Cruiser will blow it into the weeds, let alone a V8 Cruiser

Oh, and I'm fed up with fixing the damned thing.

My 130 is used as a truck so it will be getting a real truck engine in the medium term to replace the car engine that has needed a bottom end rebuild as the bearings can't take the load of the relatively mild state of tune it has and it will more than likely need a head gasket soon too as it's at that age when 300Tdi's let go and it's due another timing belt and I really should replace the water pump and P gasket just in case....at about 1/4 the km a Suzi would need repairs.

Next to break will be the R380 behind a 4BD1T.....

JC, do you reckon you could dig up the photo's of the 130 you converted to the 4BD1T ?

Only if you can find them easily though.

cheers.
