Thanks Guys, it is a bit nerve racking building a new engine only running it in for half an hour then running it flat out at 8000rpm round a race track....

The next engine build is a Guy Croft VX which should have 220BHP.....

Ian

I am delighted for you!! The car is sounding great and it looks like it is handling and braking well too. As the former owner of a 185 BHP GC engined Beta Spyder I know how great these cars can be.
Let me know when you want to know more about the VX build as I have the Volumetrico Montecarlo running and it first ran as a VX Montecarlo on Fuel Injection. I still need to complete the build of the VX FI Beta Spyder. I have all of the engine and gearbox parts including an inboard manifold with a flow deflector following flow bench development of the original horribly unbalanced manifold.

Cheers

Thanks for the kind comments Eric, I am hoping for a couple more BHP when I take it back to the dyno.

The suspension is still work in progress as I really need stiffer springs and some castor and a bit more negative camber on the front end to make the semi slicks really bite. Currently the geometry is no where near optimised for a race track anyway.

Very interested in the VX in board manifold mods. I have 2 VX's to build and considering fuel injecting the 2nd one.

I upset an Alfa GTV driver who has a supercharged fuel injected 2 litre twin spark (with Toyota SC14 blower) who couldn't shake me down the straights!!

He follows me out of pits in this clip:

Turn the volume up for this one, flat out 4th gear at Lakeside raceway...

A few laps of the same short 2.4km circuit. Had a few issues changing gear due to the gear oil used with the LSD, which meant he synchro wouldn't work once hot, hence the missed gears a few times....rectified now waiting for next track outing...

2nd link is well worth viewing.

An old post I know, but still great to read! Can I ask what fuel (Mon/Ron) you used? Just wondering why 11:1 and think it maybe down to that perhaps?
