Such an amazing car you've built - kudos!

Quick question though - how do the twin fuel tanks work?
Are they linked or do you have to swap between them?
Thank you, much appreciated.

I have kept the tanks separate, just have a simple toggle switch to switch between them, nice and easy.

This is easier for me as I don’t run EFI, if I did then it get a bit more complicated as you need to return excess fuel to the correct tank. All achievable though and I’ve put the plumbing in place so I can upgrade if (when) I want to a shiny 8 Stack system.
Thanks Hoonigan - much appreciated.
Is it just a toggle switch for the fuel pumps?

That video brought me here. Thanks for the inspiration. I plan to start something similar in a couple of years once my daily driver project I just got is complete.

What were your toughest challenges? Wiring?
I am in Canada, although we could do kit cars here, there are not many kits for the one I am looking to do and will most likely end up making it from scratch.
Hopefully within 10 years like you smile

Sorry missed this, yes exactly that just a simple toggle on my one, off in the middle and left and right for the tanks.

Small update from me…

Had an interesting last couple of months, I managed to breakdown down due to a clutch issue, for some reason I could not disengage the clutch which at the time I thought would be an easy fix, this however turned out not to be the case…



It would appear that when I refitted the gearbox last time I damaged the spigot bearing which by way of thanks decided to weld itself to the gearbox input shaft.
Two days later and with Mrs Hoonigan threatening divorce due to my (alleged) mood I finally managed to separate the box from the engine by undoing the pressure plate while still in the bell housing, all in all a sod of a job.







Thankfully all back together now and I also took the opportunity to give the rear end a spruce up as it’s amazing how crusty these cars get in a very short space of time.

Things are looking up though, only a couple of weeks after putting her all back together and exactly 3 years to the day she passed IVA, she has just passed her first MOT with flying colours. woohoo

To be honest the MOT crept up on me and it wasn’t until Monday I realised it was due on Saturday! Luckily I got it booked in ok and then spent every evening last week in the garage doing all the jobs I’ve had 3 years to to rolleyes

I now have a rear fog light and a reverse light so no bad thing and nice to tick off a few of the final jobs that needed to be done.






In other new I also had a fan shroud made to aid the low speed/static cooling, it also allows me to fit slightly larger fans too which is no bad thing.




Looking forward to the Le Man Classic in July now which is the next big event for me and fingers crossed there’ll be no more surprises before then…

Excellent. Mine's due for its WoF (MoT) in a couple of weeks. Hope it passes as easily as yours has.

Glad you are all sorted.
That breakdown guy did well as I bet it is not the easiest car to hook up on the that half trailer.

Lovely job - is it worth putting flaps on this shroud to allow airflow through while driving? Very common on OEM shrouds as they get sucked closed when the fan is running so best of both worlds.

Hey Ben,

We’re staying off site , about 30 mins away in Malicorne-sur-Sarthe, Pays de la Loire.

We will be driving in each day though, be good to catch up for a cheeky beer mate.

I did look at adding flaps but in reality there was inch a small area that is not fan I decided not too, and to be honest I’ve fortunately not noticed any difference in cooling while driving at any sort of speed.

Fair enough the covered area is pretty small!

Sounds good to me! If you're doing a parade lap and have an empty passenger seat... wavey

Unfortunately I left it too late to book any track time, however with all your media influence and insight I’m sure you could sort something for us Ben biggrindriving

Yes, I've been accused of this once or twice. hehe

Fantastic read, a great achievement.
