Now the winter months are here i have decided to put the Chevette on a SORN and do a bit of fine tuning ready for the spring .
The main job is to fit the scimitar axle with an LSD.
So i bought a power-lock diff from a Jaguar, these seem simple enough to fit with a little bit of jiggery pokery and spacer making.
Always wondered what was inside an LSD
After inspecting all the gubbins for wear i found just a slight score in two of the pressure plates.
They actually look worse in the picture so i'll just give everything a coat of oil and bolt it back together.
Another job to do is fit a proper handbrake, the hydraulic one i have at the moment has been fine up until i pressed the brake peddle when it was applied and sheared all the teeth off the ratchet So I'm going to look at fitting a cable one at least then it will be legal.
Something else i have toyed with is converting the rear brakes to discs but I'll have to see if i have the funds or time to do that.
Work should commence soon just need to get the Brownie points built up now that I'm a Dad for the first time
a thing to note with the jag LSD is that they were built with two settings. a road setup and a track set up.
the only difference was the way the plates are placed together. for road the plates were put together with two eared plates next to each other. this gave less friction so less bite. for your weight of car it'll probably be ok but if you do want more friction then just rearrange the plates.
the breaking torque of the diff* should be around 60ftlbs standard. we usually try for 100ftlbs for the race cars
*to check the breaking torque fit the drive shafts, hold one still and turn the other with a torque wrench (very easy with dumpy E Type ouput shafts) when the internals start to move read the torque. this is the breaking torque. if low then new plates will be needed or at least maybe a couple slightly thicker. I have used shims behind the static curved plate before. we have loads of second hand plates if you need any. standard thickness is 94 thou each one.
edit : forgot to say always use a diff addative for these jag plated diffs otherwise they judder (plus a mix of addative and ep90 for assambly of the plates). available from Jaguar.
what a journey ! ive been reading your thread inbetween jobs since 8.30 this morning. got to page 29 and someone said the same thing which had taken 6 hours lol. !
I expect all the superlatives get boring after a while, but just wanted to show my respect for your work and the car.
had an odd thought when you mentioned about cooling issues, then pondered about a slotted nose cone from a manta b would look at home..?
13.9 is great going. I managed 14.056 with 200bhp (fwd with road tyres), so your dyno runs versus real world performance seems spot on
Glad you enjoyed the read
I have seen a couple of Chevettes with similar slots in the front panel but i feel it would take away the stock appearance of my car. To be honest the ally rad has made a huge improvement to the cooling
Hoping to see a 13.5 this year with a few minor tweaks.
Well shock horror I've actually done some work on the Chevette.
Seeing as I've no overtime at work and the wife is still on maternity leave which means i have no money for road tax i thought i may as well pull it apart.
The aim is to get the LSD in and have the car back on the road in time for PPC in the park on the 19th of May. The main motivation is the fact they are having a burnout competition and i have a spare pair of wheels with some old tires on
The axle is now partly stripped, need to strip the brakes next then pop the halfshafts out.
Need to persuade this to come out.
Hopefully there will be another update before the 19th of May.
Wow nearly two months since the last update and in those two months not much has happened, I decided to leave putting the lsd in until next winter as if I had pulled the diff out it would of not been put back together this year.
I had taken the axle out but it is now back in the car and awaiting the brakes to be bled and the diff filling with oil then it should be good to go for an mot.
Major stumbling block at the moment is spare cash, new baby and no overtime for the last few months has really put a strain on the old finances, until things pick up at work the Chevette will have to stay in the garage , which means I'll miss PPC in the park on the 19th of May, bloody annoying!
But on the bright side this is out on Thursday ;D
