I've just read this thread, too. Bosch Gen III Injector Upgrade

Interesting. It might have been more economical to do this than have my injectors serviced.

Mine starts first time 99 out of 100 goes I never have to give it a good crank.

Yes I read that thread before I decided to get the injectors. They definitely make it run more smoothly

I found the Rover V8 inlet manifold archive ;)

I note this comment on the Thor manifold v Gems

"the throttle body has a 68 mm throttle as standard and again, we often take this out, in this case to 71.5 mm. The Thor manifold, when used with either a standard cam or a mildly tuned cam, gives a strong torque peak at around 2,000 rpm, much higher than that achievable with the Lucas plenum design, but even with careful gas-flow work the power is limited. We find it difficult to achieve more than around 280 bhp with this manifold, where a similar amount of effort on a Lucas Plenum manifold will yield 320 bhp (but with less torque below 3,500 rpm) "

Hmmmm, 320hp! :)

yea,, at 5000rpm,,,:rolleyes:
