Hi all

My RV8 powered Stag is almost ready for its MOT.

However the idle becomes rough and the engine stalls when the electric fan comes on.  Any suggestions on how to resolve this would be appreciated.

(Range Rover Classic 3.5 pulsar - 390 Holley)

Thanks

Hi

The extra load on the alternator when the fan cuts in is probably causing the idle speed to drop too low.  A work-around might be to increase the idle speed, but that will increase overall fuel consumption and, if it's an auto, increase the jolt when engaging gear.
EFI models use a solenoid to increase the idle speed when ancilliaries such as fan, aircon etc cut in.  I've no experience with Holleys; maybe something similar already exists.  Devising one from scratch could take quite a bit of work.

Try asking one of the RV8 specialists for advice, e.g. RPI Engineering.

Hi Steve

Thank you for the response...it's a manual so should be ok with a higher rpm as Its sitting at approx 800.

Thanks

Id suggest its overly lean, or possibly overly rich. Once the addtional load is added, it then struggles. Or its not idling on the idle jet, until the fan cuts in. Either way, id suggest a carb issue.

Ive got a holley on my stag V8 and its rock solid under all conditions. And ive got a kenlowe.

Thanks Roger.

BTW where did your engine originate from, and do you have PAS?

Its a stag engine, far as i know original. PAS as standard.

Put a rover V8 in my 2000. That has PAS too. Just used the original triumph system including the pump.
