I certainly have, thank you! (I'm also a subscriber to your chanel, stalker alert! )
I do enjoy the graphs and reasons for them, just need to work on my brain to understand them more! Are you going to try fit pressure or flow valves to each line going to each cylinder?
I'm sure the new clutch will be balanced enough, you have not added tons of weight to one side. Good luck!
Yes that's the plan , if i can get flow valves in each cylinders copper feed pipe , i can try to equalise the temps , , also i can change the tendency for the fueling to be lean at low rpm ,and rich at high rpm .I do enjoy the graphs and reasons for them, just need to work on my brain to understand them more!

if i can fit them just at the black pipe junction under the bellmouths that would be ideal ,
i am thinking of drilling and tapping a large unf bolt into the aluminium threaded stub on the venturi bodies ,there may well not be enough meat there , so i might have to make threaded blocks.
Re clutch , it should retain the Aston Martin DB9 ,balance , however i may haul the whole assembly down to rob walker and see if it can be balanced as a whole .

small update time .
i decided to convert to megasquirt , i had a ecu i was going to use on the tvr , so used it on this monster instead.
my new best power figures where very wheelspin limited , however i am up a bit on the venturi system of fuel delivery .
here are my development runs with the injection compared with the best venturi runs ..
bhp,
trq,
You can see that anything above 410 lbs ft on tiny thin 7.50 x 16 tyres is not gripping too well , however its safe to say i have above 450 lbs ft and above 360 bhp ..... so driving a car weighing under a ton is effortless .
Drove to the Broughton castle car show , and got 12..1 mpg with the inj very rich .
80 miles on 19 quid of fuel is much better .
the new aston twin disc clutch is working well a little noisy and "on off" switch but you get used to it .
took v as my first passenger to Blenhiem , she loved it and said it was like being in a fast expensive speed boat ,that just glides over the top of the waves ...met some lovely people there and had a great chat with them .
v took some more pictures there ..
more work to do refining the mapping on the rd as i troll around . i am able to throw the car around a fair bit now , cornering is better than i would expect ,however anti-rolls bars and stiffer rear springs on the cards .

Great to see it evolving and updating; sounds like your head's in the important bits (i.e. driving it!) right now.
Have you any plans for its wheels? Thought about some cheeky black/silver plates?
Thanks Dr G , i am thinking either wheel discs made from paella lids , or ally discs cut out to look like Bugatti type 35.. on the other hand i do quite like the artillery look of the current wheels , they are bog off heavy though .Have you any plans for its wheels? Thought about some cheeky black/silver plates?
They have a v strange offset and 6 studs so are hard to replace ..i may try to make a banded wheel to suit too.
Re plates , i have been scouring the dateless ads(like tinder but without the std) , it appears a N.I plate can be had with 3 letters and 4 numbers for around 120 quid , however a sexy 3 letter 3 number is around 400 plus , so not viable for me at the moment , i really would prefer it on black and silver plates , or early black with the 3.5" white letters .
that will have to wait until infinity when my finances are plumped lol.

SCRAMBLAGE....
WELL.
Sunday dawned bright and clea........ok ok ...it didn't .
It dawned grey and glowering ,like a sullen teenager in a power cut with no cell signal...6c and 8 mph wind , MUST be time to go to the bicester scramble then !
A 30 mile drive in a car with no roof ,windscreen ,... i am not sure v realised how cold it would be , with 60 mph wind that worked out to around -10c in yer face .
What we learnt mostly was how low you can get in a car with a sofa for a seat ............pretty damned low !
We jumped in ,and , after i had thrown out all the Harrodsish picnic basket v had tried to load us down with , (channeling her inner martha stuart ) we romped off into the glum .
Car felt a bit rumbly and was running very rich , but i knew once warm it would smooth out. The roads were wet ,and v slippy , i had pumped up the fronts to 33 psi to see how it felt and the answer was ,it felt like i was on ice , i was therefore not sure if it was the slippy rds or the high pressure tyres that was giving me ZERO feedback ..But i was all like ........whatevahhh.
We carried on for about 5 miles into the stark greynosity before it decided to let me know it had only been running on one engine .
This problem i have with the front majic jet injectors not working for a while still remains it would appear ,i thought i had fixed it by dropping gas pressure to 17 from 24 , but no .
In this instance i was doing around 50 mph on a slight right hand turn when the recalcitrant ENGINE NO 1 ,decided to join the party .
Instantly the back of the car made a bid for freedom ,like a christian spotting an open gate at the Colosseum ,and i had to apply a little opp lock and back off toot suite .. all was well however and we had both engines for the rest of the day .
now the old girl had warmed up ,and was chiming in on all 12 , it was a delicate drive on the slippery twisties to bicester , with no drama , just us tucked down as low as we could go ,v thoroughly enjoyed watching the faces of passing drivers and pedestrians as we drove by ..sometimes waving and then whipping her hand back in as she realized it was even colder out of the car body .
Got there around 10.30 , and the bloke said "you want to park in the technical centre to show the car off ". i said ...er....ok ?
They directed me to a lot of people milling around , and i threaded my 9ft bonnet through , parked in a row of cars and went to find out where i should be .
Found out, and came back the car , or where i thought it was , since now there was a huge crowd around it ,v was very excited by this , i sang froided her ,told her it's normal , but she was not prepared for the medusa effect AT ALL... most fun.
Fired up and trickled through a little tunnel into a central area , may have had my foot slip onto the throttle in the tunnel a bit . Parked up and chatted , wandered about chatted , had a very nice chap come and video interview me , who at the end remarked i was "live to "the middle east" "......so that probably spoiled the cous-cous and dates of a few million desert people #innapropriate.
Next up was time to naff of , we had become even colder standing around in the windy airfield from planet/moon Titan, and we thought we were going to get even colder on the way home , it had rained a little on the way , so at least it was a little dryer , the weather the equivalent of said teenager having found out no one else had a signal either .
Car fired up well , v rich again but as she warms up it leans off to normal , , and we bumbled out of the site... interestingly , inside the car we WARMED UP ! , with the 7.6 litre foot warmer helping a lot .
Home again with no drama .
Indoors for open fire ,hot baths ,and Sunday evening draped over the furniture under duvets ... nice end to a brilliant day of fun .
here are a few pics ..
its in there somewhere...

Oh ! i forgot to add ...
with my whole resin debacle , i hod nothing to stick on the hole , so v said she would do me a quick fill in .
i lathed out the clear boss i had ..
that lets me put in the M for medusa in there ..
then v tried a few designs ..
and painstakingly reverse panted a design on the back of the perpex , that i then coated with black gloss..
she used bits of a christmas tree bird decoration for the twinkly bits , and was apologetic that it was not as good as it could be because it was rushed and had to be done in a afternoon so it was on the car for the show .... i told her to SHUT UP ,and i love it .

I came across this thread a couple of days ago and, despite not being 'my kind of thing' I was intrigued enough by Medusa to take a peek at your build thread on Rodsnsods.
Wow. Over the last couple of days I've managed to read through all 336 pages of the most astonishing thread I've ever had the pleasure of reading. OP, your written style, creativity, skills, enthusiasm, problem solving and shear breadth of knowledge was a total pleasure to read and absolutely boggles my mind. With the ups and downs, the trial and error, the highs and lows... it would make one hell of a novel!
Medusa has gone from being a 'thing I don't quite understand' to a car I now feel intimately and emotionally connected to, so I can't wait to keep following this thread. And all from a humble taxi.
No doubt, with bottomless pockets, such a thing would be still be a huge challenge. But to have created what you have on a shoestring budget and with (as far as I can tell) 99% reclaimed and recycled stuff you've found around the house or in scrapyards - astonishing.
What else can I say? Bloody well done. Amazing. Bravo!
