Can anyone recommend some good injectors for use leith jenveys

What's the best for the above

Are you on standard cams?

 

[Andycollins]

Currently but by the time there in use I'm hoping to have the car cammed with something aggressive for sprint/hill climbs as its not a road car.

standard injectors will do fine on any cams intended to be used with stock pistons. Adding ITBs puts them at their limit, but they will still be fine.
There's a couple of decent optionsMegane turbo injectors have a lovely spray pattern and atomisation, which makes mapping them easier at light throttle, You can use any of pico design or most of the bosch design injectors really, you just have to use appropriate spacers on the rail and size the flow rate appropriately. I used some Saab turbo injectors on a williams a while back (347cc) and some VAG 1.8t injectors on a 172 racecar.

You could fit a Bosch 4 bar pressure reg. That takes the injectors from 250cc/min to 288cc/min. Or the Pug GTi-6 had 267cc/min pico injectors, slightly more but not a great deal.

When/If I get around to doing ITBs next year then I'll pop in a 4 bar FPR before mapping.

you won't increase the flow rate by that much with such a small pressure increase. it's not straight multiplication. Something like 25% increase for 50% pressure increase

What is the standard pressure on the clio's I thought it was 3 but is it 3.5?

 

[Dan519]

ph1 is 3 at the rail, ph2/182 is 3.5 in tank

Thanks Dan

That's why I used a flow calculator. Otherwise it would have worked out as more.

The above example is 15.2% more flow for a 33% increase in pressure. So it's the same as what you're saying... X% increase in pressure gives 1/2X% increase in flow.
