Top End Speeds Vs pull

[Klone]

Hi all,

Took my car down to a bit of private land the other day, and i tested it out to see what its capable of... and i found that in 5th im at redline at 120.. is this normal?

Ran out of road before i could change.. and my friend didnt want me to keep doing it lol.

Had the car scanned for faults the other week, and all i got was Lambda sensor fault but that could have been when the cambelt was changed right?

Is this normal behaviour for a mapped Cupra? supposed to be running 210bhp.. it pulls quite hard up to that point.. then starts slowing off.

Im being a bit neurotic i think... having a turbo has done this too me!

and i know i shouldnt be worried about it because i shouldnt be doing these speeds on the normal roads which i why i use a friends land

Lucky for you that your best friend happens to own the RAF and their airfields

I can't imagine that the gearing is too different for Cupra vs Cupra R is it? I would have though that 120mph would be 4th gear speed seeing as 3rd can hit 100mph

Maybe you have a boost leak and the car is struggling?

his parents own a reasonable amount of farm land the roads are pretty ****... but there is a line to follow... although he drives a car daddy bought so doesnt car if he breaks it!

I dont think the gearing is all that different either.. wouldnt vagcom tell me if i had a boost leak?

spose the only way to find out is to connect up a boost gauge right?

Not necessarily, it's worth checking all the usual hoses just in case. Do a run and see what your airflow is like, that'll be low if there is a boost leak.

I dont actually have vagcom a member here did it for me

I will have a gander at it later when i get it back from the garage.. it chirps from the DV (as it's reversed) and it does boost hard..

Boost leaks shouldnt affect the top speed of a gear, as the leak would only mean that it would take longer to get to the speed. Its all about the gearing inside the box.

 

[JamJay]

Maybe the Cupra is just geared that way then. I guess you'll have to find 6th gear before you know

hah i only posted this because its been bothering me for a while and i just though i would ask after seeing Andy_lang saying his cupra did 120 in 4th on the autobahn... :/

120 on the redline in 5th sounds a bit odd, should be closer to 130 iirc, and from youtube vids of folk hooring around

Lucky you finding a mate with some open land to play on.....

yeah maybe the gearbox is just suffering with old age.. as the car is on 100k now... unless the clutch is causing me grief.

Yeah it's nice having a friend with land... also helps if you want to work on the car as they have a barn too. bit of a trek to get to him but a good laugh.

its your bloody fault andy!

it's always bugged me... but then seeing yours makes me think "oh ****"

Im terrible these days... and seeing your thread made me ask the question.

 

[andy_lang]

Haha, wait til I finnnnaly get round to making a readers ride thread a year later, why not ehhh!! but yer, 120 red line in 5th isnt right! Is yours a cupra engine or a 1.6

you must have a different box as my LCR does around 135 in 5th!

 

[DJ-LIAMC]

I know that mine redlines at 140 in 5th (LCR)

 

[Klone]

haha *******. i will have a look when i get it back later on. i might be wrong when i say redline... might mean just as i approach it... i dont ever redline it... but i was dodging potholes!

if someone with a stage 1 LC wants to go try it id be greatful go go

 

[andy_lang]

Ill look at the gear box code of mine over the wknd, but I rekon Klone has a 1.6 hehehehe!

You got a diesel 02M in there instead of a petrol??

Check the speedo is accurate using a GPS. Have the circumference of your wheels changed?

Also, a boost leak or something like that wouldn't cause you to go slower that you are expecting at the red line. It can only be down to your gearbox, clutch or wheels assuming your rev counter is accurate.
