An extra 50 on top would be largely beyond the cars ability to lay it down properly, so would be largely pointless. Chassis mods would likely bring a more accessible perfomance gain than simply taking a D5 engine to 500NM in isolation.

Its a holistic proposition and i see little evidence that is understood in your blind power madness.
Manual M66 it would be. the thing with autos is the torque converter but no ones looked into getting a better one that I know of so there is a limit on those. manual does over 500nm no problems probably more easily enough. thats the thing going into the unknown you try it you break it and learn from it. or maybe you try it and it works just fine.

did you know the fuel pump is capable of far more 550hp in fact not that you would ever get that out of a d5. but did you also know those BMW 335d's and 330d's etc their fuel pump isn't as good as the Volvo. the bmw has a R90 pump the volvo has a r110

the injectors on the volvo are more than capable of delivering the fuel the worst case scenario would be new nozzles.

the block isnt capable of going 600 the liners will crack

the dmf is certainly capable with a different clutch without going for a paddle clutch.

straight through exhaust necessary

doo8 intercooler very necessary

all that leaves is the tuner.

How blind is that?

any more questions?

If your trying to achieve those alleged figures what braking system will you be using? Instead of sarky replies to genuine questions maybe tell us what you have done to your car already to achieve the figure that you have already. As at the moment I dont think anyone thinks your figures can be achieved. I'm not saying it can or can't,but it might help your original question.

I don't think there's anything us mere mortals can add.

500bhp is nothing these days.

Total waste of time trying to get a D5 to that power in my opinion.

Any modern petrol car of similar power will walk all over it with their 8 speed autos, AWD and launch control.

Any Telsa comes along and you've had it.

If it's just for novelty factor and that makes you happy then fair enough, but the days where a 500bhp diesel was impressive are long gone.

I know. Nearly 30 years developing, building and testing F1 power units and I thought I knew a thing or two, but I'll be heading back to primary school at the earliest opportunity.

I tell you what. Here's a tenner - the day the OP achieves 500 BHP from a D5 and I'll send it to the charity of his choice. Until then, I'll continue to get my fiction from paperbacks.

265mm diameter brakes

maybe if people stop saying stuff like blind and a waste of time etc i would.

ive already given a lot of information including the modifications needed some of which I had already.

they only dont think they can be achieved because 1. they havent done the research and testing ive gone through with professionals and 2 nobody has done it before.

things like this require extensive knowledge of the parts on the car and parts that will need upgrading to achieve it. and also testing and doing it. nobody goes into the beyond without this and expects everything to work perfectly

current mods were d088 straight pipe turbo back, GTB2260 and stage 2 map

F1 power units are miles and miles away from a diesel road car. its a totally different ball game!

i never said you could achieve 500hp from a d5 i said the pump is capable of 550hp so yes go back to school learn to read properly

god this is why i dont get on with half the volvo community because they try knock you down when they cant even punch

Dont worry I will go off and do my own thing, if it works all good for me if not at least we tried our very best with a professional to get to the goal and we learn something because we are not scared to go into the unknown.

I can do it without any input from the Volvo community as I usually do anyway, tbh i shouldn't have expected any more than what I've had before even though. Not 1 person here has given a single valid reason why it is not possible because if they did i would have considered it not possible or at least highly unlikely. I know why it's because they dont know the answer! :teeth_smil e:

265mm brakes ain't going to stop you with that alleged power. With an attitude like yours why even bother to ask the forum in the first place. You obviously know everything about the d5's apparently. Carry on your own then, achieve your pie in the sky goal. In fact I'm not sure why I'm even replying
