Some update on my F7P Turbo project

[ruzki]

Regarding the 6 paddles for Alcon i checked all the UK distributors and found nothing.

Yes I know, thats why I've posted the picture.. this friction plate does exist.. unicorn spec

I personally would go with a 4 paddle, over 6 if holding power is your main aim. The difference is the 6 paddle will spread the clamping force applied over a greater area, so more user friendly but less powerful bite.

I totally agree, but I would like to point out, that both -4 or 6 paddle- should hold the same torque, but the 4 paddle will wear faster.
I made this "more bite" experience since I have tried both and probably the 4 paddle friction plate can indeed hold more torque.
Maybe it bites more because it flexes more than the 6 paddle plate.

Hello mate, unfortunately i am from Egypt.

Wow, long way to come to a meet for a Coffee haha. Welcome to the forums anyway, I hope you stick around

That pic was from retro rides at shelsley walsh this year.

Ah mate, we had a club stand there, if only i'd known. If you saw the Silver Clio V6 legging it up the hill in the morning session, that was me

 

[DaveL485]

The clio 172/182 flywheels are definitely 60-2 trigger pattern

I think we have the BTDC value and reset point config for those on the site somewhere, defo seen some people with Adaptronic ECU's running that flywheel. I think @Brigsy is doing it too.

Really appreciate all your help, regarding the 172 release bearing, i am already running the soft pedal conversion, basically the clutch release longer arm and brackets which uses different bearings unless you want me to buy Helix Bearings for more strength.

I mean is there any difference from the normal megane 1.6 16v vs the clio 172 ?

Tbh im not sure, i just ordered everything new,figured while it was apart id change everything. I also changed the fly bolts for new ones, seems the general practice not to reuse the old ones?

I did yeah i was there all day with west mids retros. Was sat up the s bends most of the day watching the geezer in the the orange ae do his best to go sideways from bottom to top

Yeah im using adaptronic too. You have to really swinging for anything over 280 as the oe ecu wont recognise any modern injectors big enough to make uphill of that. And yeah the oe ecu wont recognise the 60-2 pattern, although if he’s running a crank pick up with his megasquirt it probably wont matter anyhow I wouldn’t have thought.

Updates:

Still waiting for the 182 flywheel to come.
While waiting i decided to rebuild another F7P engine so i can get a fresh engine with the new clutch and probably installing the megane F7R JC5 gearbox as it has longer ratio than the F7P JB3 box to decrease the wheel spinning a little bit.

I don't believe that the Megane JC5 having LSD but longer ratio will decrease the torque on the wheels.

Will start on dissembling the engine this week and will update some pictures as well.

AHHH! NO! Use the old bolts (like I did).. its more fun
I made this mistake only once!

No Megane 1 never had an LSD.

I used to use the old bolts with zero issues, even the head bolts i used use them just torque them as the userguide.

I am running turbo for more than 1 year with zero issues, as long as they are not stretched you are good to go

Thanks, yours looks awesome also! I cant recall the part numbers however as far as im aware helix only make one, i use the 4 paddle version with uprated helix cover plate. There were no other options and yes your correct they only rate them to somewhere around 240ftlb from memory. As for drivability, it is definitely heavier than stock and slightly grabby compared to stock but not to the point it’s undrivable in traffic, its fine once your used to it.

You may want to think about upgrading to a soft pedal conversion, basically the clutch release arm and brackets from a megane or 172. Its a little longer so makes the clutch lighter.

As far as limits id say your getting pretty close at 250bhp on standard internals! Mine runs 21psi of boost to make 340bhp.its fully forged, uses 630cc injectors. Not sure the standard pistons and rods would take much over 10psi, but hey, if your willing to push it will be interesting to see how far it will go!!

What brand do you used for forged ?

 

[Lee19turbo]

What brand do you used for forged ?

I used wossner pistons, pec rods, arp bolts,a kings bearings set, i stayed with standard cams but use vernier piper pullies, standard crank, 630cc siemens deka injectors, walbro 255 fuel pump, gtx2860r turbo, 3” downpipe and exhaust,adaptronic engine management. Think thats about it

Wow!
Decent setup, pec reported that this setup is good for 900 hp, so just a good ID1050x injectors and bigger turbo and you will spin 4th gear all day

Its a massive handful as it is!

Do you have any acceleration speedo video ?

Best time for me with high boost map and 95 Ron was 10 sec from 100 -200 km.

So i am looking for that time again with good clutch.

Right now i am working on a spare cylinder head ( installed megane f7r inlet valves and porting the head as well )
Will post some pic soon.

I used to rev 7800 rpm on jb3 gearbox.
Will increase the rev with the ported head

I've always reused flywheel bolts, never had one break like that!

 

[Reno 9]

Here are some pictures for installing the Megane F7R inlet valve and doing porting and polishing at home.

Thats a pretty serious bit of kit for a "home" setup!

The finish on those ports is just right, not too rough, not too smooth
