my clio with matched inlet graph

[stan*]

All the same then at the end of the day

Really?

Ive seen some shocking examples....

 

[broster@JAM-Sport]

Porting heads/inlets etc is an art, we have seen some heads which look good but perform shockingly! same with inlets on some cars we have thru the doors for rebuilds the ports are all different shapes etc, not as easy as people make out.

Sorry, I was asking lol

 

[stan*]

ah lol

well there is a couple of areas I "address" which is seperate from the actual matching. So based on that alone, they arent all going to be the same, no.

Then theres actual quality of workmanship. Somebody matching them with a dremmel isnt goin to have the same effect as somebody with various top of the range grinders (aside from build quality, better tools have less vibration and better bearings, therefore the tool chatters less. this aids the finnish immensley). Same with burrs and abbrasives.

So yes, in essence the practice is loosley the same, but the end results can be quite different.

Yup.
Recently had a couple of heads from other companies on my flowbench, Was intresting to say the least.

Guys, im booked in to have my Clio 172 FF(52 plate) inlets matched.

Jamsport are doing a before and after run.

I have ITG panel filter and Ktec exhaust from CAT back. (with no centre silencer)

Power run will be done on this setup, then with matched inlets. This is being done in two weeks so results up soon should sort out whats what

good drills got the same as you on the 172, will be watching and waiting for the results dude

 

[Sean.]

booked in on the 13th so will post results up on the monday after.

 

[jimbo666]

niiiiice! good to see you got the job done so soon Broster. glad you put them to good use, they were just gathering dust at mine.

 

[Tigger]

booked in on the 13th so will post results up on the monday after.

Can't wait now, we're as excited as you are lol

 

[jack_davey]

Broster is a legend, his 1600XE corsa was 190bhp last time I checked!

 

[Tigger]

Ughh - Corsa's! :dead:

 

[mark123]

Sean, it'd be interesting to know if your before inlets have the RS stamp.

 

[Andyman]

Sean, it'd be interesting to know if your before inlets have the RS stamp.

Sure all Cups had RS inlets as standard?

 

[Mostro]

Sure all Cups had RS inlets as standard?

Did they? Is Sean's a Cup though? :S

 

[Andyman]

Might be wrong but i always thought they did. The RR graph says Cup and his sig says Cup so guessing it is a Cup lol

 

[Mostro]

Not the one that's been done already, Sean. above is having a before & after RR session this weekend

 

[Andyman]

Ah right lol not sure then

 

[Sean.]

mine isnt a cup chaps.

as for the RS stamp, i'll have a gander when they come off for you. being done this saturday so not long

other mods taking place - new handbrake cable!!!! lol

 

[chauster]

What kind of prices are we looking at for porting the head on a 182 ??

 

[Fred@BTM]

the head? a lot!! over £1K fitted

 

[broster@JAM-Sport]

pm sent with quote

 

[Andyman]

My head was done by AWT good few years back for £600 but that was excluding fitting.

 

[broster@JAM-Sport]

we do them fitted for £1180.20 fitted

Hi all, the results are in and the work is done.

see this link for all the info you need:

I am also very interested if all 172 Cups have the RS stamped lower manifolds ..

Anybody ?

 

[Jay Payne]

not all of them, a mate of mine had a non rs stamped one

 

[Mostro]

Hi all, the results are in and the work is done.

Just to keep the relevant information here:

So now the important bit you've all been waiting for.

Before run:

171bhp @ 6227Rpm
156lbft @ 4995

That is with Ktec stealth exhaust and ITG panel filter. Car recently serviced 1000miles ago.

After run:

179bhp @ 6105Rpm
163lbft @ 5056Prm

With the mathced inlets done and same mods as above.

So an increase of 8bhp and 8lbft of torque. How does it drive? well much better actually, small differences but overall car feels more punchy, picks up when overtaking a bit better. Gets to the tops speeds a little quicker than before. Pulls better through the revs in the higer gears. Overall very happy with such a simple mod. Didnt expect miracles and i didnt get any but worth while none the less.

 

[Sean.]

cheers mate

 

[Coby.]

Good Results IMO.... I'm still in and are we going with Jamsport then???

 

[Craig.D]

can you get the same results with the 182 or does the matched inlets work better with the 172???

 

[franx]

Supposably the 182 all have the "RS" lower manifold which is good enough / alot better than the 172 lower manifolds. Not really worthwhile doing the 182 manifold matching , brings almost no improvements so i've heard/read

 

[Tigger]

^ You still get an improvemant and some gain, "maybe" not just as much as other/earlier models though.

 

[Sean.]

plus the fact that every car will be different!

its not as simple as if i get my inlets done will i achieve 8bhp and 8lbft of torque instantly. some cars will be matched ok and some poorly. Bit of pot luck imo.

recently done a 182 with rs inlets, he is a user on here

http://www.cliosport.net/forum/showthread.php?t=378561

deffinatly worth doing on the 182 IMO!

also my 172 cup had the rs lower inlet and i noticed a difference.

 

[Sean.]

apologies for the lack of graph to date everyone...havent got a scanning facility at work so will have to wait until the weekend, unless Mark you still have it on the computer at jamsport, long shot?

 

[broster@JAM-Sport]

Sean, i shall scan in it today for you.

 

[broster@JAM-Sport]

there you go

 

[Andyman]

Torque comes in a little early on the pre run does it not? Peak torque at 5k rpm

 

[broster@JAM-Sport]

not abnormal, look at the graph, has the same two little peaks in it that a few clios have

 

[Sean.]

nice one mark cheers
