You dont need to cut anything.. Just hook it up on the left hand side of the engine.. See my pic..



Hope this helps

 

[LeeroyBrown]

yikes!!! sorry about the big pic lol

 

[hadz]

i thought u had to cut intothe vacum hose? what is that bit that you have pointed out on the pic?

 

[LeeroyBrown]

there should be a nipple on there just pull it off and slip the pipe over..

 

[hadz]

i dont think im going to have enough pipe to reach that bit where you have put urs! is there another place that i can put it? i have seen that quite a few people have cut into the vacum hose that comes off the dv? where is the best place to get the most accurate reading?

Yeh you can 'T' into the vac pipe on top of the dump valve or as Leeroy said into the brake servo line. I personally fixed mine to the fuel pressure regulator as it gives the most accurate reading i found.....

where is the fuel pressure regulator found in the engine bay coz i havent got a clue where it is!in the instructions i got it says to hook it up 2 where u have!

have u got a pic please?

ive put mine on the vac hose going to the dv but the fpr hose is one of the two coming off the inlet manifold

 

[gazjones]

just looked at pic at the top mine is a different intake manifold so not sure where the fpr vac hose is on that

 

[hadz]

any1 know where it is?

wicked cheers mate! how did u run the hose to there then?

 

[-pseudonymous-]

I removed the plastic water catch tray at the bottom of the windscreen then fed the vac pipe through the rubber grommet next to the wiper motor back under the dash (above the pedals) Then all you gota do is run the pipe to wherever your mounting the gauge and 'T' into the pipe running from the inlet manifold to the FPR. But bear in mind you will need a fair amount of vac pipe to reach!

I think Leeroys is the more preffered method as its probably more straight forward and there is no cutting involved.

Also check the guides section on http://www.leoncupra.co.uk/

in the end i put the T piece in the vacum hose that comes off the DV but when i boot it the boost gauge only reads 5psi? is that right or have i got a leak sumwhere? on idle it reads 21 vacum if that makes sense!

hope sum1 can help!

I presume its a standard Cupra (not re-mapped)? When at idle it should be reading around -20ish vacuum and around 5-6psi peak boost. A re-mapped cupra will be spiking at around the 20psi mark depending on the mapping.

[hadz]

ah right thats alright then! i forgot to mention that it was standard! even tho i thought that with a standard cupra you would be able to get 7PSi?

cheers for all your help by the way CUPRA OILLIE!

mine still hasn't been remapped and mine reads around 7/8 psi or 0.5 bar

 

[hadz]

oh dear that now makes me think that i have a bit of a issue sumwhere then! i will go and give her a bit of a thrashing later and see what it tops out at!

 

[gazjones]

thrashing it dosent give you full boost if i thrash mine i get around 16 psi but putting my foot down in 5th from 20 mph up through rev range i hit 20psi try loading and letting turbo spool up on full throttle that give max boost
