- Installing the Harrop truetrac into the Holden 10 bolt salisbury diff to tuffen it up to handle more grunt and dyno day for the 308. The 308 punched out a solid 287rwhp through the th400.

I’ve got a similar engine setup in my HZ sedan, VL 304, VN heads, Crow 4626 solid lifter cam, Harrop dual plane manifold, Yella Terra Roller Rockers, Quadrajet. Your video has convinced me to buy a Truetrac and have the confidence to fit it myself. Thanks so much.
It wouldn’t hurt to pan the camera around to the bloke playing the piano every now and then. Keep him keen. 😂
He’s a shy lad apparently
Ah that butterflies in the stomach feeling,when you hold your breath on hopes and dreams. And yew made it happen.
Never had any doubt.😆
If only the diff on my VE was this easy to access 😂
Actually I still have a genuine set of Timken bearings for a a 10 bolt, thanks for reminding me man 👍
Nice one, i was told the tru trac wouldn't fix the weak point in the 10 bolt but looks like i was advised incorrectly! Will be doing the same mod.
Yeah they definitely do, the next weekest point is probably the axles after that. One tonner axles are thicker and stronger than the ute and sedan axles but you can also buy aftermarket. One tonners have the largest yoke for them if you want bigger unis fitted.
@@MCFRYMotorsport I have a 1 tonner tail shaft I think which has the bigger uni joint diameter so that seems right, seems like a decent upgrade for the money really. Cheers
Harrop also does a 31 spline centre for the Salisbury. With new aftermarket axles and the one tonner flange it makes a very strong diff. i had mine done a couple of years ago
@julesat29 It would be interesting to see what power levels they would hold with 31 spline axles, I have seen covers for the rear of the Salisbury that can support the caps also but cant seem to find any when I search.
Like your work mate enjoy your videos
awesome I'll be doin this soon
I thought you have to run a diff in for atleast 500km.
Atleast it works. Good stuff.
Maybe with a new gearset, I always just put stuff in and send it haha
Love your videos
400hp if u want it to live , axle housing and axles then become an issue . The elephant in the room is the crown wheel pinion gear set availability. As u have noticed its not a USA 12bolt or 9 inch [both these suffer from shit wheel bearings ] Use crewman [large] , hq [small] axle bearings , BOP Buick Olds Pontiac bearings ,,,, all have tapered rollers that work
Hey bro i rember how to ajust your backlash its been years since i played wiht these old girls but undo your tailsharft then you see the big nut on the frount off the diff tighten it up and it will pull the gear into the other gear an tighten up your backlash thers a spacer that is collapsable so dont over tighten it wont spring black i had to weld a tool up to hold it while i tighten it
Yewwwww up the true trac
What ratio Truetrac Diff did you put in ? Thanks
I have been running 3.36
Pinion bearings and the gears are the next week link.
Haha no more diff vids, they have all been done at some point when it had new seals fitted.
@@MCFRYMotorsport
Might want to do I tailshaft safety loop video or should I ?
@Brenton K haha I bought one to fit then put it in the to hard basket
Looking Good..!! What backspace wheels did you go with ? I'm keen to order some BCI 7" rims as well.
Just standard offset, I can't remember.
Ya didn't show us how you got the crown wheel on to the new diff far out thy are tight
I actually used the crown wheel bolts to pull it on after a light mallet hit, they are tight.
@@MCFRYMotorsport or yip cheers
Hey bro to much back lash move 1 of the shim too the other side it'll tighten up the back lash
These Salisbury diffs only have 2 thick shims on the carrier, one either side.
Hi again you will need to grind 1sim down an buy some SIM paper to put in the other side too much lass how it is an how you drive it'll let go 4 shaw
What happened to part 9 ?
The build series pretty well finished up here, the rest of the videos with this car are just the finished product.
Nice vid again. Real world! Is the car officially registered now? I have the correct Alternator Bracket for that motor if you want to hit me up.
It is officially registered now, I have the correct bracket just need to fit it.
@@MCFRYMotorsport
Where do u buy the Winx oil filter anywhere local
Ebay, but I run ryco from supercheap on this.
Hey mate, how much $$$ is a dyno tune worth these days? Haven't done one in ten years.
Depends how many hours and how off the car is but usually $500-$1000
Dont you have to adjust the pinion backlash with shims after installing a new centre to stop them grinding themselves away after 3 months?
This is a pretty sloppy install, im confident they are meshing correctly, but the centre is too tight. Its just going to put extra load on the bearings and take more hp to turn. If I had some diffs laying around I would have tried a few different shims.
@@MCFRYMotorsport true, the hard part is done, could just rock up to a diff shop and say i added trutrack can you reshim the pinion, probably be cheap af..
@4kays If the mesh is out they generally whine, the bearings could get hot on the carrier and prematurely wear being this tight but ill take the risk on that.
@@MCFRYMotorsport how is your center going? I just installed mine today. I haven’t driven it yet but with the o.g shims that came out it was tight as fuc$ to get in there. Mine can’t be turned by hand but I’d say that will change once I drive it. The mesh feels great though pretty much how it was when the old center came out.
@peatergriffin good ive installed 2 now and they both went in tight and wouldn't turn but seemed to have bedded in fine
Has anyone done 278 ratio with the truetrac
They won't fit 2.78 ratio
Red loctite on the crown wheel bolts?
They just got ugga duggas, was a very sloppy install this one but I've done heaps in the past and never had any issues.
@@MCFRYMotorsport am all for the duggas but with red loctite. Guaranteed not to come loose. Great channel bro. Missed your rig at scummernats this year
Great upgrade mate, won’t have any issues with the tru-track, fitted one to my FG turbo Ute, AU XR8 and the old XD as well, no issues, smoke for days out of all 3!!! 😂😂😂
Change the plates to MCTRY 😅
weld it weld it ect
Is it tru you got a trac
What ratio did u put in
It has 3.08 ratio in the rear, I would have probably rathered 3.36 but this is really good for cruising st 110 so I'll leave it in.
What is the cost of the diff upgrade
$1400 for the truetrac and the bearings
