As fitted to rsi/xr3i etc.
Am I right in thinking that after drilling the airbox for better airflow the mixure will be affected? As in weaker and will need richening to compensate?
cheers.

Alex that is what put me off, I thought it must affect the vacuum control on the flap, but as said plenty seem to have done it! If I get no joy Ill revert back as I hate crappy idling!

Nah I dont thinkso mate, I've set cars up with the airbox off, stuck it on the RR, put the airbox back on it and no change. the flap moves relative to airflow and obviously whatever position that's in gives the correct amount of fuel if the metering unit is calibrated correctly to start.

Are you sure your not on about turbo'd cars with KE jet there though Dave? Would be a mammoth task to set a RS1600i up without the airbox fitted!

Yea I'm talking about S1/S2's but same principle with the metering flap, no?
Done the same with an XR4i turbo, with K-jet!

If your right dave I wonder why I cant get a decent idle on the car? And usually when you open the throttle screw it increases revs, but it is making it die - hence me thinking it was running lean and opening that screw to make it idle higher was making it leaner!

As said flap moves relative to total air flow, as the pintle for the fuel is with the flap won't make a difference, adjusting the pintle will though as this adjusts it's position relative to the airflow/flap so increasing or decreasing fuel flow for the same given air flow.

That's still quite a lot in terms of adjustment, but it could well be that it needed it! best just to see what the gas anyliser sais, makesure it's as far into the tailpipe as you can get it
