View Full Version : Max BHP from an F7R
Ben's got 215BHP odd out of Craig's T/B'd beast on a standard B/E.....How much more could you make and how lol
The Clio Maxi had 260BHP iirc .....more than that? money to burn tackle lol
Cheers

can you use a turbo or do you have to stay N/A? wasnt there a clio turbo from greece boasting somewhere near 500bhp? turbo on it was about the size of a mans head lol

i think you can use a mild low comp turbo without changing btm end.
yep u can, maybe using a thicker h/g altho some dont apparently
would like to know how the 500 bhp 1 lasted tho lol....not long i bet
250 shud be fairly accessable

lol..in my hands it wouldnt last long... nor would I..lol.
If you wanna get that sort of power from a clio then you really have got to be stupid. Why? If you have the cash to push anything more than 200, then why not just buy another car??
Surely the whole point of 'fun' motoring is based around the standard output. Sure my willy aint the fastest, but I don't want it to be either. But its still a great hoot to drive.
I saved my cash and kept it for the GrpN scoob!!

i like the fun in extracting as much power out of a car as i can, saving up for bits and looking forward to getting the car back!!!

Its the whole stupidness that's great about it... getting massive power out of a little tin can. surely thats all the fun...
Well this little monster has about 450bhp...
But it's orientations are quite obvious :twisted:

thing is tho mate, a lot of ppl quickly become used to the power of the clio, and want more, u sell the clio for 4 grand say. wot u gunna buy?? sure u can pick cheap scoobs up, RA spec 2800 atm, but why would i wanna do that?? other ppl will be expecting to get beat by a scoob, so its a nice little surprise for em wen that little clio has jus wasted ur scoob......
sure the scoobs can be tuned to get a lot more out of em than the clios....but more fun?

Turboed you should be able to get a reliable roadworth 350bhp out of them I would say, but the bottom end would need strengthening. Custom shorter conrods would probably be needed aswell to drop the compression as skimming the pistons would leave them a bit thin.
See ya
Matt
i had a 280bhp scooby a while back and the clio is twice as much fun to drive!!!
ben reckons with some bottom end work it would be about 230bhp ish, altho i knew of a renault 19 with steel bottom end, stupid cams, and the works running about 270bhp!
in fact:
F7R block with new bore and stroke from 82.7X93 to 84x90mm
forged steel bottom end and forged JE aluminium pistons
all lightened and balanced to the max,
Sodemo F2 Megane head and cams and Jenvey 50mm throttle bodies
Motec M4OO managment
274bhp@8000rpm and 195lbft@6250rpm with 178lbft from 4750 to 7750 peaking at 6250
298bhp/ton at 920kg 0-60 4.56 0-100 10.65 1/4 mile 12.59@112.36mph
Don't get me wrong guys, I like fettling too and there is a buzz in getting more power out of an engine than standard..I guess I have the luxury of having the load lugger 2.2dci Laguna, the rally prepped Scoob (running Motec M800 ECU, and in B13 spec over 420Bhp and a shed more torque).
The willy is a weekend toy really, so I guess I am trying to say that I would rather spend the cash on other stuff now than making the minimal power outputs to the clio (although it has been de-catted, chipped and gas flown), next up would be cams and head work, but I have no requirement for it...
Still, if you want to go for it then I would be 100% right behind you guys..its your cash...do with it what you will.
imo yes its good to make the car faster and see how it compares to other clio's but when u have a duel with say a scoob uk spec etc and it dont leave u for dead then its more rewarding in that way, esp to see the look on there faces when i clio is still sat with them lol :D

its all about the look on there faces :lol:
Well there is no way my willy would keep anywhere close to the scoob. Not even on a track...never duelled with a UK spec STI in the willy. Will do a back to back test when I get my new roadgoing spec scoob in the new year, before ripping its guts out to convert to rally spec.
I'm not surprised a Williams can't keep up with a 420bhp Scooby! Incidentally, I thought group N was more or less standard?
Standard...no chance!
As soon as the Motec went on it it unleashed massive amounts of torque with the correct mapping. Weight reduction was a good chunk too, tricky bits inside engine..and diffs..Reiger suspension
There is no way any self respecting Grp N car is anywhere close to standard trim. Yeah sure you can easily turn the road going scoob or Mitsi into a grpN car - roll cage and fire stuff, plus bag tank, seats and harness' and air restrictor and you are away...but there is so much more you can do...
Just putting in a Grp A 34mm restrictor and a new map transforms the car..but B13 is where it gets really good!!!
I didn't realise Grp N allowed so much modification! I knew that there was some complaint over Grp N regs not being strict enough, but I didn't realise it was that extreme :shock:

gp n...bahh group b is where its at..or was at
Forgot to add...... N/A lol
Craigs answered my question :D
You and your turbo gibbo :roll: :P
Cheers guys

but a 200+ clio will be as quick if not quicker than a 300bhp scooby once rolling! and no doubt a fair bit quicker on track IMO
imagine the face on the scooby driver when the clio spanks him! iv seen it enough times of the past 3 month ;)
Not sure there, but I can't say I would be that interested in taking the scoob on track, completely different set-up all round and would need major work and different software set up too.
I would be interested however to track the Willy and see how it really handles. Trouble is, road going, and race going sets ups are so different...how do you find the ride quality of your semi-track prepped clios when back on normal roads?
If your talking pure NA, and packaging restrictions were resolved (alterd crossmember and bulkhead) then 280-300bhp could be touched on, but with the port design your not going to be able to really hit more than that without some serious cylinder head surgery (milling ports out to beyond the water jackets and welding them solid to build a higher port).
Craig, yours will be capable of 230 in reliable trim, you can push more, but even your engine isnt 'wild' in the true sense of the word.
If your talking FI, i wouldnt hesitate to point a finger towards the 600-700bhp region. The chambers are great for det resistence, block is strong etc etc.
I'm sure I've heard of a 600 FI F7R engine not sure on the spec for definate but it was very long not sure how much beyond the block (even that was moddified I think) and head (modified again) was the same.
Would be good fun finding a good gearbox or having the self preserve not to go through boxes ever few days.
Not sure what clucth you'd use over 300hp as Nick had toruble with his one I belive with 240 or so.
lug drive clutch, or multiplace cerametallic.
At that sort of level your simply talking about money, and the amount needed to adapt bespoke items to handle the power.
weird though, as honda box's for the B series engines can handle about 900bhp with only a few bits changed.
