N75 query!!

[The MoffMeister]

I know this has been done for the beezer boys but im wondering if its the smae for leon cupra's, not LCR's.

Firstly i know the valve controls the dv etc and amount of boost, but the different types what do they mean!! I've heard of J and F i think, but which one would be best for a mapped car..

Have done a search but nothing major to read about!!

Cheers all!!!

p.s best place to buy also!!

Stick with the STOCK N75 (F).

Remaps are designed to work with the standard components - change them and you'll need to change the map to suit.

N75J's have prooved to cause a lot of problems for people. Very few (CupraUK springs to mind???) have had a good experience.

ok see what your saying there, so if i got my map adjusted to work with a different n75 would there be a better one for this or stay standard as i know alot of people go to the j version for some reason!!

 

[Pabs]

if you search on this, you'll find that most leon drivers stick with the standard F valve, as it gives the best results. I think there is very little difference between the valves, they just adjust when the boost is applied... i think the F is earlier boost, and J is later....

Not really sure. As i've said there are loads of threads on this. I'll see if i can drag some up.

As Pabs says, more bad stories than good. I like mine for the delivery but it has knocked a few bhp off on the RR. My 1/4 mile times are better but that could just be because of more practice or luck

I'm going to a SCN RR day in February, lets wait and see how I compare to other stg 1 Revo LCs, not just the peak bhp but across the range.

Brendy's post is quite scientific so is probably the best comparision that has been done.

there u go - knew CupraUK would be along soon

I'm just a sucker for the poor J... it gets a bad rap!

Stick with the 'F' mate. I replaced mine with a new 'F'. Only really need to start looking at the N75 when you've got stage 2 remap. Best place to by is www.vagparts.co.uk and look under the VW passat section.

See you Sunday.
