Mike, I'm not sure what the story is behind the V12 Ferrari!!! The photo was posted on CC a while back, and I just had to keep it because people wouldn't believe me...
My website's a beauty isn't it
I had all good intentions of doing an Andy
www.cobralads.com but I found that I didn't have the time,ability or inclination! I just post a few large photos at that poor excuse for an incomplete website to save having to upload them here. If you want to see some more Cobra photos from all over the place, I have a heap stored at

The last motor built on a 9.2" deck had the latest Yates design ported by Bennett Racing. They cost about $14000 bare from Bennett, and didn't flow the numbers they should have!?! My friend gave them a bit of a massage and picked up nearly 30cfm at full lift.... The car ran a 3.9" stroke billet crank, dry sump, crank trigger etc. First and only meeting at the track and it ran 10 flat before being kicked out. He actually rang a friend in the grandstand while going down the track to say that it launched well!!! What a goose....
I rang my mate today to find out his thoughts about the A3 heads but he wasn't home. I promise to let you know when I found out.
My car is just a rough old thing. I spent FAR TOO MUCH money on the motor. I worked out a budget to build a tidy street Cobra, having factored in numerous little tricks that I wanted to incorporate. I spent the entire car budget on the motor alone
This has just had a snowballing effect on the build cost because now I needed a racing transmission (G-Force $5K+), 1350 unis, billet axles, massive intercooler, big dollar fuel system, sophisticated ECU etc etc. All of the time and money is going into the mechanicals at the expense of the body/paint.
I'm glad I did bolt the pan to the motor, because the car actually cam smashing to the floor when a jack seal failed, crushing the pan. It absorbed the blow and the internals were untouched
The exhaust was fabricated by a friend of mine who used to build custom pipes, but retired at age 45 vowing never to do pipes again. Persistence will get you everywhere, so I had him do the headers and the sidepipes. The headers are in fact 1 7/8 mild steel HPC coated, the sidepipes are stainless. He made some perforated tube packed mufflers with 3.5" ID and 5" OD. I'm a bit concerned that my engine tuner wants to run the Motec computer rich on deceleration to cool the cylinder bores during my roadracing outings. This usually results in 2 foot flames out the pipes in other cars he tunes, so the muffler packing might not last long!
The Z-bars have to be equal length top to bottom to work effectively. This prevents the diff from binding up. Running the upper bars backwards is the best option because that puts all the rod ends in compression, which is where they're strongest.
My fuel system as it stands now is:
Triangle Engineering 20 gallon alum cell
-10 to 15psi Carter lift pump
-10 to 3L swirl pot
2x -10s to 2x Bosch M/Sport pumps
Fabricated s/steel Y-Block to Bosch filter
-8 to engine bay
Y-Block to 2x -8 lines to billet 1/2"ID rails
Holley 95lb/hr injectors
2x -6 out to Bosch 2 inlet Regulator
-6 return to swirl pot.
I'm hoping I wont have to use a third Bosch M/Sport pump, but we'll see when it gets onto an engine dyno. That's in a few weeks, and I'll hopefully be able to borrow a digital video camera for that.
Geez - if I can type this month, maybe I should put it on a website
