Iron block so I can potemtialy vintage race. 4pt roll bar, the 6 point seemed to really restrict vision, custom seat and 6 point harness.
Bladders installed by Dennis.
Problems imo if you are going to do any type of tracking are the motor should be tied down from bellhousing to car from factory, and there is no reason not to do solids all around.
The brakes are not really up to the potential of the car, but then Gt40s never had great brakes. factory should offer a track brake upgrade option, something from brembo, baer etc.
Latest problem is the right front bearing loosend after 500 miles and is shot, will see if hub survived. Imo its a result of poor qc in SA.
I also would not do a 4bbl again. While the power is there, the car pulls enough gs on corners to cause one bank to flood while the other starves. That means a stumbling motor coming out of bends, whereas more precise power allows one imo to put it down sooner and acuratly hold the car at the limit on exit. 4bbl just seems too inprecise, but will try redo floats and primaries. However you cant prevent the fuel from sloshing to one side of the intake manifold on corners.
There is a reason they ran webbrs in period, More precise fueling, fatter and flatter tq curve even if h suffers a little.
That all being said, this is by far the most fun car I have owned. But its going to take 10-20k more and 10 days on track to be fully sorted as a strong really fast track machine.
Basicaly its undoing all the softenign spf did to make the cars streetable, most of that softening dosent do anyhting in term of streetability, and then relearning some things they learnt in the 60s..
As to the development I am doing now, thats what it takes to do a serious track machine.
While I was able to run down a new porche turbo at the track, this was more a driver thing, but the car as it is now is probably going to slay a regular 911c2s or new c7 vette.
I still need to loose another 12 secs per lap. Lets say 6 from sorting the car furtehr, maybe even 10 with brake ugrades, and another 5-7 secs from sorting the driver and bringing him up to speed.
