Volvo D24 VNT Project.
« on: February 05, 2018, 05:32:39 pm »
hello all. this is my first post, and im not entirely sure this is the right place to post this, but...

this is my D24 to end all "D24s are crap" lark. also to showcase my fully mechanical VNT controller, if the thread gets interest ill make a full build log about how much a pain in the arse its been. still, worth it if you ask me.

the whole plan of this was to make an engine that you can start with a screwdriver and fix with a £200 halfrauds socket set at the side of the road in the middle of nowhere, go as well as a 5-6 year old diesel that needs plugging into a supercomputer every time its air filter gets changed. and so far it does that. my target was an E60 BMW 535d.

the last time i did a dyno run a few months back she made a smidge over 200bhp and 400nm torque.

now it can make the 520nm rated clutch slip in top gear, there may be an issue with the clutch, but i need to do another Dyno to see for sure. It sometimes breaks traction in a straight line in 2nd gear, with 205 profile Continental tires, needs a locking diff really...

boost comes in hard around 2000rpm, through to 2600rpm ish, making 30 PSI on the GT2260v from an 530d BMW, all the way to 5000rpm, by then the governor starts cutting fuel, although it does rev to 5400rpm.

I can post a youtube  link thing, so of you search volvo 940 d24 vnt  dyno into youtube  you will find the video im on about

if there are any fellow D24 people around who are planning power, contact me and we can have a chat, not many of us around.

many thanks

Will vg

Welcome aboard!  I haven't seen much "D24s are crap talk", at least not on these forums.  They only thing that's been discussed is that there could be oiling issues with #5 and #6 under certain circumstances, but that's about the extent of it.

I'd like to see your mechanical VNT set up.  I'm into the 5-cylinder diesels, so a lot of your 6-cyl stuff can give me ideas too.
