Ok mate no problem. Sorry I couldn't help you out.
from wikiSurely that's the other way round?
80 acc 45 dec?
My understanding of a 1.5 was that dec was 50% of acc
some lsd quote ramp angles from vertical (along axle axis) whereas Gripper quotes their ramp angles from horizontal (along rotation direction).A 1.5-way differential refers to one where the forward and reverse limiting torques are different but neither is zero as in the case of the 1-way LSD
mine's obviously a custom ramp.Current ramp angles available are 30/65, 40/65, 45/45.
Paul any chance you could nab some pictures of how the the 5th gear selector fits in with the other two selector rods. Not sure if mine is correct
Nah. Officially bhp is nothing attached to the engine and measured in lab controlled conditions, ie measured at the fly. Tge brake being a brake applied to the flywheel to calculate torquei thought it was hp is fly and bhp is wheels
mate we are pushing no where need the maximum of the diffs. i remember a birdy telling me like something around 400, as its the same design as something else and they saw that figure. mine was 150/150when john at Gripper once told me it could handle the 160ftlb my setup produced, I'm wondering if that meant 160 at the fly or at the wheels.
he said their diffs worked fine on other racing cars over 500bhp, but I think those have the full two-sided clutchpacks whereas mine only has the 1/2 sided clutchpack so the poor beville can withstand only half the max load.
the dyno printout that Ed at Fusion gives out I believe are readings from the wheels? so the actual torque going through the diff in a low gear could be much higher?
this is just guesswork at the mo.
SirChris was urs dyno'd on Ed's, what was ur torque readout? did ur planet driver have any defects like mine when it was apart?
chris have you ever taken yours on track or was it only on public road? is that estimate 150bhp/150ftlb?mate we are pushing no where need the maximum of the diffs. i remember a birdy telling me like something around 400, as its the same design as something else and they saw that figure. mine was 150/150
Works well on tarmac and gravel, better on gravel than i was expecting to be honest. At the moment the diff i think is offering more performance than I as the driver can fully extract from it especially on gravel.
lol i suppose ur setups alot meaner n u drive it harder. will get back to you in a year and with track abuse and see if the diff is still fine.my dyno printout was 162HP
I read that trying to calculate the actual engine output on a rolling road is a rough estimate at best cos there's so many tiny little parasitic variables that will affect the accuracy of the result including:
tyre traction, sidewall rolling resistance, tyre pressure, tread depth, drivetrain inertia, drivetrain friction, oil seal friction, CV joint friction, all bearing friction, etc
for the actual engine output to compare against the manufacturers original spec, nothing can match hooking the engine alone to a dyno, but that's impractical for most ppl.
chris have you ever taken yours on track or was it only on public road? is that estimate 150bhp/150ftlb?
the birdy telling you 400 sumthing? was that for a gripper diff with an offset clutchpack & beville washer, over 162ftlb and combined daily/track circuit abuse?
I think as a daily on public road the diff is fine cos there's not much stress going through it for long (and the past evaluation during the engine bed-in supports that).
whereas, since I took it on track, the constant 162ftlb WOT loads and shock loads from upshifting with a heavy flywheel seem to push it upto and beyond the preload washers operating limit and the past 3yrs of constant fractures seems to suggest that.
john at gripper got back to me saying send it over and they'll rebuild it under lifetime warranty over 3days.
I asked if that washer will be removed to stop this happening again or whether it'll just be rebuilt back to the same insufficient setup and most likely fail again on track, which is very inconvenient. I can't justify having to do this EVERY year wasting both mine & Grippers time & money.
if it keeps breaking I'll prob have to look at either a VLSD or an expensive geared LSD for more reliability. anyone fitted a torsen/quaife/eaton diff with the standard speedo gear on a k11?
for that price as 2nd hand, certainly an affordable alternative option to consider if this one fails again and my income improvesWorks well on tarmac and gravel, better on gravel than i was expecting to be honest.

Will PM you a price.
yikes. suppose tis all this black friday/cyber monday/etc online xmas demand and also reduced workforce thats just overloading their infrastructure?Royal mail has had a propper melt down over the last few weeks.
My 24hrs special delivery signed for took 9 days.
