I'm selling mt Dragy GPS as I feel I've learned what I wanted to from it. I measured performance before and after fitting a lighter flywheel. Check out their website for more info www.dragymotorsports.co.uk New is £145 Looking for £100 posted to the UK. It comes boxed, with all original kit, ready to go. Monitor your 0-60mph, 60-130mph, 100-200kmh, 1/8 mile, 1/4 mile, 1/2 mile performance, and more! Dragy uses high speed GPS satellites to accurately measure your vehicles performance within 1/100th of a second. The Dragy software automatically charts slope on all timeslips which you can then post to forums or social media, share with friends, or even upload to the Dragy leader board. The Dragy box is extremely compact at 1" x 3" (25.4mm x 76.2mm) and can be set on the dash when testing and stored in the glove box or center console when not in use.

I don't know, but physics would suggest an engine will spin up faster with less mass. perhaps they could use my data?

One thing I forgot mention, and it's a big thing for me, was the improved smoothness of gear changes.

Hi Folks, after trawling this forum when trying to figure out the benefits of the lightened flywheel, I came across lots of varied answers, but no hard numbers. I wanted to be able to measure the benefits (as much as an amateur mechanic can), so I set about trying to measure performance. The only real variable I can measure is 0-60 time, as responsiveness, engine braking etc is hard to put a number on. So, did I improve my 0-60 time?

Selling my headset as I don't use it enough. Great for listening to music, talking phone calls (clear and effective in the Caterham), and communicating with others via a radio (not included. Includes a charger and a radio cable. £290 inc delivery

If the type 9 is the Mazda 5 speed, I recently made a video of me doing this job..

If there was a nice version available comercially, I'd buy one!

Hi Scott, yes, sounds like a sensible approach!

You're correct, my book says 1.2 L I was asking about oil on a FB forum and the conclusion there was that new editions of the manual says 0.8L due to the seals leaking. Mine don't leak, but I've put in less than the 1.2. Probably 0.9 - 1 L will be in mine. check for your own car.

I've attempted my first oil change on my BMW open diff. if you want to avoid the same mistakes I made, you can see how I did it here.

Sounds like good advice, thanks.

No idea. Guess that's what makes me an amateur mechanic. Perhaps that's why it didn't take the full 2 L of new oil? perhaps the other drain plug holds the remaining 100ml.... I did see some info about some oil in the turret, I'll maybe do that next year!

Diff oil video coming shortly!

I've documented my changing of my gearbox oil on my Caterham 310s if anyone is interested.

Hi Jonathan, appreciate you considering my eye safety. I did the old "eyes shut" whilst blowing technique. I still strip wires with my teeth. Don't tell my Mother.
