The trip to vmax RR was delayed a week as Stuart had a break in. All set and ready to go.  20190704_084019_resized.jpg   101K   1 downloads

Arrived at vmax 3 hrs later safe and sound

And here is were I found out that my aldon amethyst is not working properly. As a test I set it to 12 degrees advance and the strobe was showing anything between 11 and 20 degrees. Stuart says these mappable ingnition set ups rarely work and advised a basic vacuum dizzy with elec ignition. Got it ordered yesterday so should arrive Monday.

Bit of a waste of a day really and a waste of my free RR set up by Stuart

that's annoying to say the least.  hopefully the next session will be a bit more productive

I need to find a RR nearer to me. It just costs too much, with time off work, renting a trailer, petrol etc.

have you considered https://www.northamptonmotorsport.com ?  they're not too far

 

not used them myself, but they seem to have had some nice cars on their RR; Nick Masons 250 GTO among them

Bad news on the Amethyst. I've been toying with buying one for months for my supercharged 998. Glad I haven't now.
Does it just bit hold steady at all? How did you lock the mechanism in the dizzy, could that be the issue?

you lock the dizzy by putting strong springs in that don't budge. to be honest I just bought one from aldon already done as the motor I used was from an SPI.

I would normally use Aldon as they are only 15 miles away, but I used Vmax because of the charger. When I say nearer I mean round the corner

might be time to dump the dizzy?

Agree, I can't imagine the problem is the amethyst  as much as what's triggering it - which would also be there for any dizzy.

 

If it's an SPI motor it will have had a better timing sensor originally.

[HUBBA.HUBBA]

Stuart advised to get this. For 60 quid its worth a pop

would I need a different flywheel for this. Mine is a pre verto

The Bikini style top and the 'Glove Box' are great mate.

Quite and for the set up you have, this would be ideal.

 

The shift in timing is somewhat 'odd'. I can't see it being the Black Box, it would be in the Pick-up arrangement - that is, if it;s not something silly.

 

I also question the fitting of a distributor,with a Vacuum Advance on a Boosted Application.

I've now got the new dizzy to try, £65 so not too bad. Stuart a vmax swears by the vacuum dizzy. Its what he has on his car. He also said the best engine management is an emerald (on his injected kit).

We'll soon see. I've just upgraded my old gunson strobe to a digital Innova one from Oz that displays the RPM too (should make it more of a one man operation), spoke to the DHL driver via my 'ring security camera' and he told there is an additional £27 import charge to pay...bummer!

 

I was pondering the vacuum on a boosted application situation. It must just advance on idle to 1500rpm and then no more 'assisted' advance on boost, just mechanical advance.

 

I'll just plug in the new dizzy and see. I wont rip the amethyst just yet.
