Superspec Gearbox/diff Ratios

16 September 2017 - 09:03 PM

AndyW and I have been comparing notes on our Superspecs and among a lot of other differences we have found quite an appreciable difference between our speed/RPM ratios.


For the test we both used a GPS-based Speedo, as the speedo in the Superspec is known to over read because the wrong speedo drive wheel is fitted to the gearbox


To maintain a true 60mph in 5th gear I need 2500rpm.   Andy has to maintain 3100 rpm.


(As an aside, at a true 60mph I see 66mph indicated and Andy is seeing 72mph)


We are both using the same wheels, and we assumed we were both using the same drive train, MT75 (off a LHD V6) and a standard drum brake based Sierra diff, but obviously not. 


The difference in indicated speed would lead us to believe we have different gearbox ratios (although maybe only in 5th?) but could different Diff ratios have the same symptoms ?   Or maybe a combination of both ?


 Anyone any thoughts ?  Any other Superspec owners who could do the same test ?




Lincolnshire Meets For September

06 September 2017 - 09:53 AM

This weekend is looking pretty rough, so our opportunities are:


1.  Horsepower at the Hall/Gearheads at the Ground, Sunday 17th at 13:00 at the Newrak Showground.    Hopefully this time it will be on and the weather behaves.  For those who haven't been before, this normally has a huge turnout of cars and is a good day.


2.  Pub lunch on Saturday 16th.    (Let me know if you are interested)


3.  End of Season Bash on 22-24th.


And looking ahead, don't forget our usual attendance at the Corby Glen Sheep Fair on Sunday 8 Oct.  If you haven't been before, it's a nice day out at a 'typically British' village fair.  More details to follow.



Superspec Rear End

26 August 2017 - 12:16 AM

AndyW and I are thinking of buying a complete drive train as a package of spare parts for our Superspecs.   Unfortunately it turns out the donor Superspec has the optional disc-based rear brakes whereas we both have the standard drum-based cars.   So the diff and drive shafts are of the bolt-on type whereas I think ours are the push in type  (might be wrong, not a suspension expert).   So:


1.  Am I worrying unnecessarily ? or


2.  Should we forget the back end and just take the engine/gearbox/propshaft ?


3.  If we get them, is it as simple as trying to find some Sierra rear discs  (common or rare ?,  easy swap over or difficult ?  different trailing arm setup ?)


Be grateful for any advice from the more knowledgeable of you, particularity other Superspec owners with experience of the back end.





Lincolnshire Meet For August

02 August 2017 - 08:20 AM

There are 4 opportunities this month for a get together:


1.  Newark Autojumble  ( This Sunday (6th Aug) 10:00 at Newark Showground


2.  The weekend of 12/13 August. (Open to suggestions, depending on weather)


3.  Gearheads at the Ground, 13:00 Sunday 20th August also at Newark Showground,


4.  Stamford Car Show, ( 09:00 Sunday 26th August.


Unfortunately I can only attend the first two as my daughter has just produced a new granddaughter so I have to fly to the Cayman Islands to meet her (hard life :))


Any thoughts ?





Stamford Car Show

10 July 2017 - 07:58 AM

Takes place on 27 August and many of us attend every year.  See http://stamfordcarshow.co.uk/


The reason for this early post is that they use an unusual business model.   If you have been before they send you an invitation to attend well in advance.   Unfortunately they limit the attendance to 300 cars, so if everyone from last year accepts the invitation then no new people can attend.   That doesn't happen of course, but it does mean there are VERY limited spaces left for new people.   So, if you haven't attended before and want to go then you MUST register now.   And make sure you put on your form that you are from the Robin Hood Owners Club and Register, that way we get a Club Stand if we have enough people attending.


Be careful to read their reply as well.  Last year a few people thought they had been rejected but in fact they had only been rejected for the 'run out', not the actual show.   Very few cars are allowed on the run so that is nearly always fully booked well in advance.


Finally, I seem to have a spare invitation if anyone wants to go but gets rejected.


Can those who have already accepted their invitation let me know so we have an idea of numbers.


So far I have
