Thought id post the link to this.

His 172 cup with the standard stamped RS inlets and his ported inlets, rolling road graphs before and after.

If that isnt proof they work i dont know what is

Ah the very foundations of forum knowledge are shaken once again

[Andyman]

Will this work well with a ebay chip ??

 

[Tigger]

Isn't this already on here?

 

[jack_davey]

good post, I'm tempted to have mine done now!

 

[whatisjustis]

good post, I'm tempted to have mine done now!

And mine mate...

 

[tim124]

it might make a difference but the exhaust was changed too so its hardly conclusive.

Also it says the inlet was matched to the head

but its the step that there was on it to the head that caused the main problems

so simply sending your inlets off isnt going to solve anything

 

[d4ve86]

as said above he worked on the head and changed the exhaust so that isnt a gain from just bolting on a set of matched inlets, i did fell that the car drove better after i fitted my AWT matched inlets and i had the RS Stamped ones before, iv got some pciutres somewhere which show the difference between the two.

Get some pics up dave if you dont mind

+1 Go on on Dave!

Im sure it does smooth it out and i would consider it but only matching with my head.

£120 (correct?) for some inlets that still dont match my head is a joke. Especially as i understand some are done by just sticking them on a CNC machine

 

[broster@JAM-Sport]

sorry when it says matched to the head it was matched the the gasket. not the head.

to be honest i was expecting a far amount of long timers who know better to rubbish the figures, however all i know is i removed my rs inlet off the car, fitted a ported rs inlet which was enlarged, matched etc, fitted a yozza sport cat back, did another power run.

im not going to lie about the results gained, what the point.

 

[broster@JAM-Sport]

these pictures are pretty shocking as i did them with my phone. but it gives a better idea:

 

[gtruk]

would jamsport do anymore inlet matching as they are more local to me

This inlet matching isnt a new thing. Its been on the 172 / 182 scene for years!

Yes youve posted a result that shows you gained 20 brake just about but theres no way that figure is correct, not even anywhere near it!! You can hardly get 20 brake from cams and mapping let alone exhaust and inlet work!
The cars not even mapped ! :S

For all anyone knows, you could have dialed in a low transmission figure on the rollers deliberetly to get this blinding figure, post it up on forums to make folk get wet then subsequently make a packet selling inlets.

Doing inlets is worth it on the F4R but 20 brake with a exhaust and no mapping, mean while back on planet earth,,,,,....

 

[broster@JAM-Sport]

i didnt say it was new, i did it because other have done it and had good results, i decided to try it.

pmsl +1

 

[whatisjustis]

So out of interest, which rolling road would people say WOULD give an accurate reading?! FFS.

 

[Andyman]

Any non L.A.D Motorsport sourced one


10 brake max from this mod mapped.

And normally people flame results as they're not done on the same rolling road on the same day.

Then one that has still gets flamed lol.

even if they arent accurate, they have still given a good comparison.

i do agree that they can make a difference but as andy says 20bhp is too much. A good companison would have been to change just the inlets.

There are people on here that have spent thousands and have only just achieved 20bhp

 

[caister]

I changed only the inlets in this thread apart from adding hillpower gaskets but they would not increase bhp.

http://www.cliosport.net/forum/showthread.php?t=358476&highlight=matched+inlets

I thought the figures I got were a bit optimistic and they were done in RSTuner which some will say is not very accurate. However I tried to make it as accurate as I could given the tools availible to me. I think the shape of the graph illustrates the difference that they make.

Also remember these were PH1 inlets which are known to be pretty bad in the first place so 12bhp might not be a bad figure to go by.

 

[Fred@BTM]

one of the OE test cars gained 13bhp

i've seen 13bhp gained off a viper remap and cat back, people don't believe it

 

[Riley!]

jesus what its peoples beef. Exhausts give a gain, matched inlets give a gain. End of

 

[Tigger]

sorry when it says matched to the head it was matched the the gasket. not the head.

Can this be done when the inlets are matched too?

 

[TooneySonic]

jesus what its peoples beef. Exhausts give a gain, matched inlets give a gain. End of

yes it obvious they give a gain but 20bhp for these two combined without a remap to suit is quite a remarkable figure

I'll be posting up figures tomorrow when i have my car mapped to suit the cams i've had fitted

I'l be happy if i see 20bhp more since the last time i was at RStuning (made 156 standard, 164 after map), since then i've had my inlets done, fitted decat plus the cams

 

[Adey.]

what cams you gone for buddy?

 

[TooneySonic]

bought yozza's schricks (spelling) dude, cant wait to see the results

How does it "feel" with all that done, compared to standard?

Because the guy looks like he plans to market them and the sales pitch figure of 20 brake is unrealistic especially with no mapping.

Getting any sort of power out of the F4R's is bloody hard work and very expensive.

 

[Fred@BTM]

matt gained 13bhp without mapping on his (not jams)

 

[broster@JAM-Sport]

having been trading for over 15 years we have developed alot of kits, mainly ford and vauxhall, however with track cars becomming more and more common with customers, and the clio being a perfect basis for alot of people to start from we decided to act on this and see what we can do.

the inlet was done on my own car, we chose the yozzasport exhaust to use, the rolling road results were what happened on my car, i was shocked at the gain, were not going to sell these as "Gain 20bhp with this cheap and easy mod" until we have had this mod on an independant rolling road gains wont appear in our adverts.

Hope this clears things up, were not out there to make false claims.

 

[Andyman]

and if you did the same mod on another car, different day different rollers chances are it would be a totally different gain.

Fair doo's if this is just a example figure but you know what forums are like. Folk will read Yozza Exhaust and Jamsport inlet getting 20bhp then rush out spending their hard earned thinking they'll get exactly the same when in reality majority probably wont get anywhere near it.

In general you'd be lucky to gain 20bhp from mapped cams so to gain the same from just those 2 mods, the car must have been built by the hand of god, or the rollers lol

 

[broster@JAM-Sport]

i did hear that god did have a play with a few 172 cups on the 7th day, but that may just be hearsay.....

 

[Saner]

broster

Would you be interested in confirming your results on an indepenant Rolling Road at the end of Jan? about hour and a half drive from where Jam Sport is based?

 

[Fred@BTM]

in reality the inlets gained him 5bhp, the "if calrsberg made exhausts" gained him 15bhp, he's just too scared to admit it

 

[Tucker]

broster, is this the yozza race or road system???

 

[Slammed172]

Lmao.

Might get one of these sometime soon.

 

[r8byb]

Im going to jamsport and having a rolling road done before and after next month, so we'll see the results i get
