Steve,
They were reconned and tweaked standard turbos . As soon as he said that I knew they would never achieve 200mph . Also, if they don't change the gearing or hike the rev limit, it won't do above the 175mph "book" speed, as this speed is achived on the limiter (7k) in fifth. I know, as I've maxed one out on the A47 .
Also FUCKING TIFF NEEDELL AND WASTEGATE CHATTER AAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH .
Chatter? Wot Chatter? I swear that sounded like a blitz dumpvalve
FFS NO dumpvalve makes that noise!
Only reason cars with Blitz/HKS etc dumpers make that noise sometimes is the spring rate is so strong the vavle dont really open, giving the car chatter....
Rich,
S4s are just 2.2 litres charge-cooled turbos, the GTs are V8 are low pressure non-intercooled twin (tiny) turboed 3.5 litres with 75bhp more - big difference .
Ish. The Sunbeam uses the 912 engine, whereas in turbocharged format it is then called the 910, but these are all derivatives of the original 907 engine.
