Skip,
How much space frame twist is there with 230bhp (although the
torque figure is more relevant)?
I'd guess most of the twist is in the middle section but a decent
roll cage should stiffen it up properly. I assume you do have
a roll cage rather than just a roll hoop?
Whilst I''ve been rebuilding my Vixen S3 I've bought an Impreza
WRX which is quite amusing but not as much fun as the TVR.
Where do you get your BDA parts from?
Regards,
John Upham
