Volvo 1031 diff conversion:
Made a set of alloy collars to go in the diff housing to check for straightness with the use of a 38mm solid steel round bar:
Also got the axles changed from 5x108 to 4x114.3 stud pattern:
Made a diff jig:
Put the volvo diff in it:
Got some new mounts laser cut to my own design:
All tacked up:
Welded the centre using the ol' plate method:
Put the centre in the diff with a set of 4.1's, new bearings, backlash and pre-load set:
Also designed a catch can and made that. It's a atmo venting style with internal baffle and will use fuel cell foam as the filer media. It fits in the space behind the strut tower next to the wiper motor and should have enough capacity to satisfy CAMS. I'll post some pics tomorrow of it installed.
Render from Solidworks:
All taped up and ready for welding:
The welding I got a mate to do as he's much better than I
Radiator, oil cooler and intercooler mounted:
Used some new bolts to make it look swish! Pretty fancy for a race car. These bolts are from www.bolted.com.au.
First Start!! Pretty happy it fired up without any real issues once we put a decent map into it.
No oil leaks, no fuel leaks, no funny engine noises, happy days. Now to put it on a trailer and take it to the dyno to be run in and tuned to 16psi.
Drilled/tapped the original bonnet stand off holes and fitted some bonnet pins
Splitter mods, test fit before paint
Dummy fit up of the splitter after paint
Front tow point
Rear tow point laser cut to my design. It bolts where the original part once lived however the 45mm hole is CAMS compliant.
Starting to look like a car again
Drove it from the front garage up to the shed in the back yard... so it moves under it's own power now!
Fitted the rear f/glass bumper, boot hold-downs, etc. Back of the car is finished.
Dyno tune left me with mixed feelings...
Pro's... it didn't blow up, the rings bedded in and there was no oil in the catch can after many many dyno pulls, and i got to drive it around the street and it was mad fun!
Con's... couldn't get the ECU to turn off the VVT, so the power flatlines at 6000rpm due to the advanced inlet cam. We did a run with the VVT off and it made another 15kw so there's an easy 180kw at the wheels once this issue is fixed.
Graph (note, this is a low ready dyno)
Robbie at wolf faxed this fix to us, need to use a second Aux output to turn off the VVT power:
First drive after the run-in tune... https://youtu.be/_bouHya5hW0
Finished shot of the engine bay:
A couple shots of it at the track:
Finally a video (https://youtu.be/2WrKG2YyEnA) of it's first laps around a track. Driver needs HEAPS more skill, but for now i'll blame the low rev limit, old tyres and learning the car as the reasons why i was 5 seconds off the pace :-) next time we're at the track it should have a 8500rpm rev limit and the VVT working, so i'm keen to get into it!!
Thanks for looking!
I can't believe I never noticed this build thread going up, it's seriously impressive! great work
Very nice build, a set of sports cams for disable vvt and a little more lift are going to make the engine fell like a racer !!
