My cup feels really restrictive!

[type_rdriver]

As the title, my cup feels really restrictive from about 2k rpm to just past 4k rpm on full throttle in any gear really?.

At first i put it down to the stupid k&n it had fitted to it, but today i fitted a pipercross viper and it does feel better but still has a massive FLAT spot! Is there any reason for this?

my car is on 45K miles BTW

 

[Gym thread]

viper ftl, best off with standard air box and uprated filter really. and to be honest cliosports dont really pull hard till after 5k, go on lad give it some welly

 

[type_rdriver]

But it is really flat mate, sometimes it feels normal and will pull a little but most of the time it is very flat below 4k rpm.

Will an oil change and plugs be better? Also do they have iradium plugs??

 

[Gaz_]

Vipers are w**k. They induce flatspots, i fooked mine off after a few months. The opening to the filter is very small, its actually smaller than the two entries on the standard airbox..... Standard airbox and replacement ITG filter is the best set up on a budget

 

[type_rdriver]

I have the universal one mate and it's alot bigger than the one for the 1*2

 

[Andyman]

Your sucking more air in with a IK so of course theres the potential for a flat spot. Thats why folk map cars to iron out dips and flat spots, set up and match fueling etc

Re-set the ecu (disconnect the battery) for half a hour.

 

[CrippsCorner]

I have standard induction and the car doesn't move until 5k

Get it remapped with the Viper on there.

please try and bear in mind you are in a 2.0 clio you're not going to feel any real pull at any rpm. even at 5000rpm it's still pretty poor in the grand scheme of things!

I'm not expecting warp speeds, but there is defintly something not right between 2-4 rpm. Like said some times it is fine, but the majorty of the time it just doesnt pull at all like the car has no torque??

Any more suggestions, please

werd.

as has been said u do need to rag it around 4k to feel like it's shifting, below that i generally find it's quite sluggish and more of a gradual increase. i've had mine for a couple of years now and it still catches me out sometimes

 

[Henry]

i've been reasonably impressed with the torque from mine from low revs - i think it pulls well for a relatively peaky engine. can you drive another car to be sure it's not just your perception? have you checked your plugs for colour?

lmao what are you on mate? mine pulls everywhere.. just much more noticeable after 5k. By 'in the grand scheme of things' do you mean comparing it to cars 3/4/5/6x the price?

Yeah!? Compared to a Ferrari it's a snail lol, but compared to the 206s/Fiestas out there it's pretty nippy for what it is!

 

[type_rdriver]

I shall try changing the plugs to see if it makes a diffrence.

What plugs are recomended, are the super 4 any good?

 

[whatisjustis]

Change the coil pack.

 

[scott7912]

I say standard box + a after market panel filter and acoustic valve removed. Its the way forward!

 

[MikeLYR27]

loose the viper mate, thats your problem, they suck balls! Get an itg panel filter!

Any evidence to back that statement up?

 

[type_rdriver]

I find it pulls better with the CAF undone, instead of connected?

 

[Alan]

Maxogen if you want a proper bit of kit if not as Gaz said ITG filter in the standard box..

 

[rare]

Are there any test results to prove which method is better? The reason I ask is because I have been playing around with both the ITG filter and a viper IK and cant find much difference between the two on the road, other than the fact that the viper sounds that more throaty (obviously!).

I cant say I have noticed any flat spots or degrade in performance compared to the ITG though?

Cheers mate, just what i needed to read

 

[Ex-User (19928)]

There was a Cup that Fred saw make a very big gain on the RR with a viper and a remap. 13hp is the figure I have in my mind, but I could be wrong. Either way it was doing sub 15 second 1/4 miles.

 

[rare]

Thats a pretty good gain. The reason I asked was because I know from experience that word can get around a forum and before you know it a product has a bad reputation when not many people have much experience of it. I am sure there are some people on here who have used a viper and had a bad experience but it would be great to get some dyno results of IK's!

 

[Eckascliovalver]

imo my cup doesnt come alive until after 5k and its running fine and normal power, go and drive a 1.2-1.6 car for a couple of days and then drive the cup again, it will feel normal

and if your still not happy go and get a rolling road done, see what the figures tell you.

 

[sammyhale22]

I messed around for months with air filter setups, eventually I relocated my battery to the boot and removed my airbox altogether, put a BMC CDA straight off the throttle body with a cold feed pipe down to the wheel well. It pulls like a b*****d at the 4k mark and it pulls and feels more responsive in the lower rpms too!

 

[Peperami]

His cup probably feels very restrictive now

 

[Jonff]

This thread has been dug out of the archives hasn't it? Lol.

 

[rexe]

My 172 in std form with a itg filter and std airbox was aweful, even worse with the standard exhaust. So as with sammy i binned the std airbox moved the battery to the boot and now have a halfords £25 filter with a feed direct from the foglight.

I also binned the backbox for a few weeks and it made the car a whole lot more responsive and it certainly shifted over the standard setup. The system was fooked anyways and the box was blowing so rather than it fall off mid corner i took it off

Same with chris's 172 his backbox fell off on the road and it turned it into a beast again, he also runs an open induction system.


ha ha ha ha, Just looked a the date as well... back to 2008 we go

 

[ash197]

Lol, well if it still counts then remap is needed to balance the extra air intake!

 

[.GAZ.]

Did u get the problem sorted Kev?

As im interested in the engine for my ph1...

 

[gaz44]

please try and bear in mind you are in a 2.0 clio you're not going to feel any real pull at any rpm. even at 5000rpm it's still pretty poor in the grand scheme of things!

What kind of bs are you talking? No real pull above 5000rpm?

It's actually quite good in the grand scheme of things. What are you comparing it to?

 

[Jonff]

PMSL. You should just buy the whole car off him Gaz

Done!

 

[type_rdriver]

Done!

Lol bringing up old threads!

Prob was sorted with a ph1 box and itg filter!!

 

[.GAZ.]

I have a nice ph1 airbox ready for it lol!
