out of curiosity - What for? Both Clio Cup and Clio R3 Maxi run the same in-tank fuel pump (80 lph) with built-in 3,5bar pressure regulator. Why do You guys want to change it? Is there sth wrong with stock fuel pressure (especially when aiming in 220 bhp figure)?

black and gold with black cable also good
I'll ring ya when I've slung a few coffee's down my beak hole!Aiming for more than 220bhp though, I'm not going to start putting figures around because that never really did me well last time! But there's going to be potential for a decent amount more.
The issue is the Meg/R3 injectors I previously ran I am being advised to ditch them, and for now run stock injectors and stock fuel pressure and lines etc - it'll be fine for 220bhp as you say. However after that I need to increase fuel pressure, I need to do this the easiest and most reliable way, personally I'm much more familar with a return setup, however if you can simply change the in tank pressure reg on the sender for a 4 or 4.5bar item that would be fairly easy too, but ITB's are better with a return was certainly the information I use to work to.
I thought that 3,5bar pump should cope with around 250hp made by R3 Maxi Evo. Thanks anywayblack and gold with black cable also good

Yeah but R3 Maxi uses the Meg injectors though, so could do 250bhp 3bar or less. About 460cc iirc.
Ashford use the 197/200 injector on all their race builds but with just higher pressure, around 330cc they say but have a much better spray pattern suited for N/A. I've got 8 x 197/200 injectors sat at home so will send them and use the 4 best. Be fine for day 1 but then I'm just planning for the next step at the moment - but I wan't my hoses to match! I've got red/blue fittings and silver braided hose right now.... just don't work with the LY paint :lol:

No worries, and of course the easiest option of all is use some IWP162 injectors on stock pressure, 377cc I think they are at 3bar.
You've got me thinking. I'm running around 220bhp on stock injectors and fuel pressure. From rough calculation I've made, that's 87% inj. DC! Don't know exact BSFC for F4R-832 though.
Seems I should consider upgrading my injectors as well. I've read on CS.net iirc that megane injectors have a good spray pattern and are used in R3 (so can't be bad) which seems oposite to what You were adviced.
P.S. IPW162? never heard of them, have to do some research

Yes well I went for the Meg/R3 ones because I heard they were good spray pattern and obviously large enough. However Ashford say they are no good for a N/A build.
IWP series are Magneti Marelli PICO series. Most used to use the 043 330cc, but from what I can see it's been superseeded by a 162. ~£350-400 for a set, but would be hassle free.
CS.net reckon the 197 injector is are around 230cc I thnk I read on there (or maybe 280cc), however Ashford say they are closer to 330cc. Anyway I have 8 of them I'm sending them next week to use the 4 best, so I'll soon have the info first hand.
What cams and compression are you running for 220bhp then?

I've read somewhere about stock 197/200 injectors being 330cc - may be that it was You writing on this forum though
so yeah, having them test-flowed would clear things upStock compression, Schrick 288 cams, vernier pulley on the exhaust cam - did't tweak it though because cambelt cover was in the way :thumbdown:, Clio Cup/R3 airbox, Clio Cup cable throttle with upper intake manifold to match the throttle, Clio Cup complete exhaust with manifold, standalone ECU. Made 216,5 on the independent rollers at 6900rpm - after that revs power band fell rapidly since the car was hesitating (suspected TDC sensor fault) so pointless revving it higher where the cams could actually show true gains.
Long story short, didn't have time to solve it yet, It was most probably the reputable tuner who turned out to have a worse day since the ignition map, primary trigger and other bits in the map are fuc**d - he never did Renault before but it's no excuse.
I suspect if we could rev it till 7800 (con-rod bolt changed to allow for it) we could hit 220 mark easily.

Cool, yeah Shrick's I think you'll hit up to 220 but no more as the exhaust ports on the head start to choke the engine from around 215bhp. Most I've seen on stock mk3 head was 224bhp on Dyno Dynamics: ITB's, high comp, 405 cats so getting wild, but it flat lined at 7000 all the way to 7700.
Anyway I think we derailed Mitch's build thread :lol:

Not much of an update as have been very busy with other stuff..its an update nevertheless!!
These arrived from Holland..
cup racer rear beam with spherical bearings and radiator support bar...
..Which have since been dropped to be powdercoated upon picking these bits up...
Very pleased with the vapoured bits, they were rotten! Reason for this isnt to be a bufty but it makes things so much nicer to work on the car, makes it easy to spot any problems which may occur and i beleive makes things work better too.
Thats all for now..told you it was small!!

Unfortunately for you no, they are the same so will use the ones which have already been done and just keep the pictured ones as spares.

Thanks Samben, decided on the cup racer epas for a few reasons, main one being its alot lighter smaller unit, that and the trw motors, designed for motorsport.
contact in Holland...Martijn @ Kool Autosport.
massive update coming up.....
