Matched inlet by Alex at Carlton fitted

[ChrisR]

About a month or so ago I bought a second hand inlet manifold and plenum for the 172.

Initially I had booked it in with BenR to get this matched, then I pulled out as I wasn't sure if I was keeping the car.

I went along to pick the manifold up (chap I bought it off left it with Alex at Carlton for me) and got chatting to Alex as normal. Told him why I'd bought it originally, he then said he used to do this kind of thing on his old cars and he seemed quite keen to give it a bash on my spare.

So not wanting to be rude I left it with him and then a couple of weeks later it's now fitted.

When I went to pick the car up the Alex said he reckoned it was noticibly different Now it pulls better from lower down and then has a second wind at around 5k when the usual kick comes in.

Had a proper blast tonight just up and down the ring road and it does feel a lot better, bit more frantic. Had a couple of runs with the Gtech doofer as well, seems to be a little better there too.

It's going back to the same RR I went to a few months ago so will be interested to see the difference.

Depending on what happens, if I do keep the car I'd be tempted by an RSTuning/BenR remap and then no more!

So if any of the guys down here fancy/need a local place to take the car for a matched inlet Alex at Carlton gets the thumbs up .

Still didn't get the big red clio with the engine in the boot as the courtesy car though

Evoo.

Do you know why con men are able to gull seemingly intelligent people like you and me ? It's that weird facet of the human psyche that demands we should be liked and valued.

No data exists to prove ''ported manifolds'' cause significant power gains.
On the other hand I have data to prove their worth is minimal.

You have data to prove that the peak power was minimal iirc? Do you have scans of the before and after curves we can see? What were the mid range gains? Or are you purely into peak power figures? So far I've not seen your data that disproves that manifold matching is a load of crap, I have your word but no data.

I don't doubt this has improved things slightly, it's bloomin' obvious when driving it.

But I guess you're still bitter.

And I'm not seemingly intelligent, I am intelligent, I have a pice of paper that says I am and everything.

 

[ja.jack]

Will you please stop calling me bitter!! I'm just trying to get the true facts accross.

where are these facts then? I dont know what got your goat, but I like to see the facts.....

 

[ChrisR]

As I said, I'm yet to see the facts, just your word on it.

Before and after graphs, plus some kind of RR calibration to work out if it's out by a percentage.

For instance, my 172 went on the rolers at powerstation and hit 183bhp with a cat back exhaust, not likely! At the same time many other standard cars over-read, so by working out by how much and taking an average I could roughly work out they were about 7% over.

Chuck the before and after graphs up and I'll be interested to see what's up. I still maintain that whlist top end might not be hugely improved (as in your original thread, Ben says there is a ceiling that these components will hit), mid range should be.

Got my before one somewhere, and as soon as I've done the "after" graph (second week in May though ) I'll stick it up. Only change will be the manifold and an ITG panel filter.

I've also noticed that it seems to be 182 owners who aren't getting the bigger gains, at least in ja.jacks original thread.

 

[ja.jack]

OK Dave and Evoo,I shall try to get all graphs up. Three in all. Standard.
GroupN. GroupN+manifold. Watch this space.

Cool, will be interesting for all I think, always best to see the comparisons mods make.

A pity the grpN is there though, would be nice to see it on an otherwise standard engine, will have to wait to get mine done

Of course what happens if you're graphs do show little gain throughout the whole range, yet someone elses show a notable improvement? I think there are too many inconsistancies with these engines to really give definitive answers to what gains people will get.

 

[ja.jack]

Good points Evoo, but might make the younger less experienced members not take the hype for gospel.

 

[Dan_cup]

you only have to read a few posts to know that its not a consistant mod which varies between cars, even that lads that do the mod eg ben say it varies becasue the manifolds vary so much.

the only memebers who take the hype as u put it are the unintelligent ones who dont read up.

im not sure what has put u off them so much but if u got naff all gain does that not mean u had a good manifold to start with??

mmmm read with interest.

i went to get my 172 chipped in plymouth. 159 bhp.... removed the air intake and gained 8 bhp.proving that the design was actually strangling the air flow. we got the car up to 181.6 bhp in the end.
air flow is important..the casting that renault make are very poor. 2 inlets are smaller than the other 2..you can see this with the naked eye.

i did not tell chris that his car would now beet a tvr but that the car was noticeably more responsive at the lower end of the rev range.

i don't rip people off!!

 

[ChrisR]

it won't???

 

[Ads_172]

I would say it's inadvisable coming onto a forum and banding words like 'con men' around when referring to trusted members and garages within this club.

 

[kully]

^^ agree , most of the ppl i've spoken to say it's decent worth while mod , ok granted it reacts differently with different cars but most ppl are happy with their inlets done

 

[E-ray_172]

i got inlet ported/re-map/cat back and i defo notice a differnce and at rolling roads i was getting better bhp then standard 182's.

 

[Dan@SJM]

I Did my own on my 172,noticeable difference and Markcup who didnt have one fitted, but had a GroupN ecu, all our other mods were matched:
IK, Aftermerket exhaust and I was keeping with him on a standard ecu. I then had a play against Rob669, who had a ph1 172, same as mine, but with a panel filter and exhaust and i puled cleanly away from him.

Ads172 now has my inlet and reported a noticeable gain i believe

 

[Gaz_]

imo evey little helps.

 

[Ads_172]

^ Yep, feels much punchier lower in the rev range and seems to get to higher revs much quicker and 'easier'. Also a lower MPG as well!

You mean higher mpg, lower consumption?

 

[Gaz_]

Well mine were done by ben, this coupled with a decat, and yesterday a maxogen all helps. I have beaten every 172/182 up for a blatt, i even got one guy wave me down in his 182 asking what i'd had done. Its either these mods or maybe its because its a Cup, but thats a different story :quiet:

which part of the filter is this mate? as my 172 is std at the mo,and im intreged bout this

 

[Dan_cup]

might mean the cold air feed with the air flow regulator thing on, just ripped mine out yesterday in prep for new cold air feed pipe

it was just hanging in the arch and the horn is a shockingly mounted to, it can just flap about. quailty!!

No, wait, I'm getting confused! I meant lower mpg - as a telltale sign that it's performing better at the expense of using more fuel!

 

[ChrisR]

ahh I see I'll give mine a good test this week, driving to work then up to London in a week will stick a good 700odd miles on it.

mined improved after the re-map

Not this chestnut again! Let it drop lol.

 

[Peperami]

Hmmm, i thought...

Most of the mods commonly made are to add more air (manifold, exhaust, air filter etc)

A remap would add more fuel, creating a better mixture, and thus more power, but worse fuel economy?

basically we removed the air filter box and just for the rollers we let un-filtered air in...8bhp instant gain!!

 

[BenR]

weird, when i tested it i lost 4bhp :S

Finger out off the nostril at last Ralph. Now it seems you have the hots for Sean.

Dont know what's the most disgusting.

Dude, Seriously don't know what your problem is with me but quite frankly can you drop it or f**k off.

Jack, you weird or what?

 

[ja.jack]

You're the one with the problems mister.

 

[Peperami]

Lol! Think you're taking the fact you didnt get huge gains from your inlets a little far, dont you?

 

[ja.jack]

Peperami. Are you and wiggum ''warm brothers''?

 

[Graham Gooch]

Whatever.

 

[Peperami]

Sorry fella, i left school a long time ago


Right, back on topic before this gets closed...

 

[Lagerlout]

I had my inlet manifold ported by a very reputable tuner and have to say that the difference was minimal. Guess I'm just unlucky. lol

BUT that is the whole point of why this mod is even considered. The castings are very different from car to car. I've been told by several tuners and have seen two manifolds side by side with my own eyes which were obviously different even to the naked eye. Thus there is always going to be varying levels of improvement.

I had an RS manifold on my 172 as it was one of the very last lot (b******s probably knew about the 182 and never told me lol) so had less to gain from the outset.

 

[Tom]

Well that was worth reading.

There are some children on here.
