Mine made 197 bhp. Do a search, been discussed to death in the Engine section on here;

I've not had anyone even hint at any disappointment with 438s that I've fitted, the same cannot be said for other cams in the past. You won't regret it, they're fantastic.
John, won't make much difference between the 2, but 438s would be easier to sell on if you ever removed them as they work with standard inlet a lot better than 421s

This is what Laine said about the ones he had in his recently and then removed them again:
Lol, for noise alone definately, as those ktec induction kits (keep wanting to call them JMS ones as the first one I saw was on the old JMS car years ago, made from two bends rather than a one piece but same thing) make loads of noise and the cams certainly exagerate it.
The 197 cams I have just fitted on our RS2 car have changed the induction noise quite noticeably as well.
thats impressive bud im defo gonna get em now
Snap! This Rich's mate? Rich used to own a euro 206 and now a CTR
Cheers guys ill defo be getting them ive so far got KTR 2 RS induction kit with KTR recessed with decat and matched inlets and im already running a JMS pop and bang map with the cams and a custom map will i be near the 200 mark then lads
I think 200 is going to be more than a little optimistic TBH
I'd go 421's john with ITB's and aftermarket ECU or even supercharge it
Yea thats a bit high i would hope for about 190 all engines act diffrently aswell i must say ever since ive fitted the new KTR induction kit its completly changed the throttle response and i feel my torque figures are now back up with the decat so im really pleased

190 is in real terms a world away from 200 with one of these engines, you are unlikely to see 200 on a standard engine plus cams unless you bolt an RS2 or set of ITBs to the outside of it.
Even 190 though would be a seriously quick car as 1*2's go.
Yep your not wrong dude i was looking at an RS2 but its quite steap so i decided with the cams with belt changes and its still £400 cheaper than the RS2 lol me clio goes really well i no with the cams ill certainly scare some big cars lol
RS2 isnt cheap, but unlike cams it gives really good gains at the bottom of the rev range (cams if anything will give losses there)
Depends what you want your car for really as to which suits better.
Ive got one on hot cams and standard inlet and hate it on the road really (power band too narrow for my tastes) and one that until recently was on RS2 and standard cams (now 197 cams) and love it.
RS2 is good on track too just because it extends the useable rev range so far, but then thats not good for reliability if you are revving the hell out of the car, which is why Ive just gone to better valves and ARP rod bolts so that I can set the limiter to 7800rpm to make use of the way the RS2 breathes so well at the top end (same issue you get on throttle bodies of course)
There is no easy answer to getting big power out of the F4R sadly really. Throttle bodies are about the least compromised performance wise but then are compromised in terms of emissions compliance at MOT time etc and are relatively expensive.

Yea the RS2 gives fantastic gains all round the rev range the F4R engines like any n/a costs so much 2 gain BHP hopefully she will be ready for the shows next year shes halfway there i just need coilovers new brakes the cams and wheels sprayed and refirbed it will be great to meet all u guys i previously owned a BG 182 a few years back unfortunatly i crashed it but im glad im back in the scene shes off the road till march so ill make do with the Ka for now lol thank u for the advice bud uve really helped

You can always get bodies later on when funds allow, with the cams already in there you will be in the ideal position for it
1*2s are epic little cars, wish I'd got into them sooner TBH, only had ours a couple of years now.
I didn't think you rated ITB's :S
Haha i think the cams will be the last of mods the mrs wud kill me otherwise lol it will be a great car when its done its really clean and shes only got 49k on her im tempted for a LY megane r26 F1 in the future but after driving 1 i really do think the clio is much better
What was guff about it?
The lack of an ICV means that you have to run with the throttle open enough to suit cold starts in winter, and then as a result it means that to prevent the idle being higher than ideal you have to r****d the ignition when the engine is warm or it will rev up too high, this results in less efficiency which puts HC values up so if its an older engine thats close to strugglign anyway it can push it over the edge, so I think its a fair statement that it is compromised when it comes to the emissions requirements to pass an MOT.
And of course if you arent running closed loop, which many ITB installations arent you've got other problems too from that, although Im sure you would argue (as would I) thats not a specific limitation of ITBs just of people cutting corners installing them.
Why on earth would you think that?
I recently built this for porkie off here for example:
This is one of my own previous personal cars:
As is this:
As is this:
Ive had loads to do with mapping or building all sorts of other ITB cars as well, and even to this day I still love ITBs for certain applications, I just dont think on a lightly modified road going F4R car they are the ideal choice in most situations so I dont join in with a lot of people on CS who think they are the b-all and end-all.
Agreed like I said, I wouldnt personally do an ITB install these days without closed loop.
Plenty of other people with ITBs and less friendly MOT testers have had issues even if you and me personally havent, not least of which because to get the most out of ITBs tends to require either an expensive uprated sports cat or a decat, and most people go for the latter, lol

"The problem with ITBS/cams is all that lag!"
To quote a post of yours from the South Central Krispy Kremes meet thread the other day.

Lol, just a tongue in cheek comment about the fact that compared to a turbo (for which the costs are similar) you end up with very little torque.
For a fast road car, Id much sooner use a turbo generally, as would most car manufacturers TBH
Its a far more reliable way to get a good amount of power (ie 250bhp+ from a 2 litre engine)
Mine too, but like you my engine wasnt borderline on HC to begin with, some peoples are, and its those people that if they add bodies are likely to get a problem.
Likewise starting hot or cold no problem and transient fuelling all good as well, but it took a lot of hours of mapping to achieve, which is something a lot of customers dont want to pay for, not a problem when you can do it yourself though of course like me or you, but like I say, its a compromise you dont have to make if still on the standard ECU, so for a lot of people sticking with that makes a lot of sense as renault have done all that expensive setting up already.
Ill do it if i win on the euromillions tonight boys lol u cant beat the sound of ITB's
Im sure we ALL agree on that
ITB BG 182
Well I dont know much about MOT's but I have had these ITB's for around 3 years or so now and MOT time every year it passes well within reason on emissions.
They are not expensive to maintain either, clean the filter out every 1k miles or so, top up on oil every so often and get a carb syncrometer for about £20 to make sure that they are running properly between the bodies every so many thousands of miles (you dont have too but i choose too)
They can be picked up 2nd hand for just above the £1k mark, seen a few on here.
Unless your going for big numbers on the bhp thing, then itbs aint the one, supercharger or HBK turbo's are it.
Did anyone say they were expensive on maintainance? Ive certainly not seen anyone do so on here TBH. Unless you are talking big power in which case the engine itself becomes very high maintenance compared to a turbo one, but not the actual bodies.
If you get a quality set like Jenvey then you shouldnt ever need to spend anything on them really. The AT Power ones if you use them a lot have some issues from what I have seen, but even then an occasional rebuild isnt the end of the world.
Economy will generally be slightly lower versus a standard inlet or RS2 as well, although those cars where its much lower, its because of other issues normally not the fact you have 4 throttle plates.
Its the AT Power ones mate, far too short and also too fragile really, not what I would have chosen at all, but its what was already on the car when me and Mike rebuilt the engine and Porkie was keen to keep them so that he didnt have to go to bonnet pins etc which is fine as its his decision of course.
I'd have gone Jenveys and much longer if I had the choice.
172
yeah iv seen AT Power bodies and im not overly keen on them.. they seem to narrow and seem asthough theyl be restrictive compared to jenveys.. longer the better but nvm aslong as hes happy thats the main thing.. what figures did this make??
