Viva GT: Prop shaft

So this afternoon, I slipped under the car (no mean feat!) and un-did the propshaft and made a note of a few things: The prop only has about 8-10mm clearance, so it might be bottoming out (compressing in fact between gearbox and axle?) as the axle moves through its range?...

Dyno data analysis

Okay so I have the data from the Toovey engine dyno run some years back, and I now have a second set of data points from the rolling session at Northampton Motorsport and the numbers do have some correlation (as one would expect). There are some data gaps in both...

Viva GT: earth calling

Today I have added a new earth to the car, so as well as the nice big earth post at the rear of the car, I now have a 110amp earth lead direct from the battery to the front chassis leg on the drivers side. From the battery following the...

Viva GT: what next?

It’s been two weeks I stopped working on the GT, and a week since the big show I was aiming for, its been a quiet two weeks of taking stock of things both with the Viva and some other very important decisions in life. I will not bore you with...

Viva GT: Bottom pulley

Okay I am back from seeing lots of folks who own Viva’s and its given the push today to have a look at the GT bottom pulley. Fist off I agree as a steel pulley its not going to be a clear a signal as an alloy pulley would give...
