N75 Race valve

[JIMYU]

yeah its fine. I do have the EML and TC light on permanently but I'm quite sure its not n75 related as its running fine....still searching for a kind vagcom user

i take it you stil get them lights on with a C F J valve on?

I still have the EML on with a n75c so it's deffinately not related.

Mine is spiking at 20- 23 psi and holding about 18..

 

[p34ch3y]

not realy sure about this H valve

spikes fairly bad dont it

 

[JIMYU]

I'm happy with mine, doesn't seem much different to the J to me reallly.

but if i was spiking at 20 and only hold 10-12, i think I'd be swapping to a J

maybe mine's working better because i had it mapped to a J

 

[p34ch3y]

thinking about putting my F back on

 

[p34ch3y]

i will have to try make a vid of what going on with mine at the mo it flicks up to 20psi then it likse somethings let go it drop back to 15 realy realy quickly like it just let go

 

[JIMYU]

Here's a clip of mine if its any use. It normally spikes 1 or 2 psi more, but it wasn't under full load here..

 

[p34ch3y]

god i wish mine held like that

 

[p34ch3y]

well ive been in contact with the people i got my h from of ebay because i was starting to think the valve itself eas faulty this is what has been said to me


David,

We get this request a lot and have taken returns in the past but the valve never seems to be faulty. A replacement valve will not solve the issue.

The H valve will only working properly if you are using high boost levels, if this is happening, you may need the N75-J valve which is an upgrade to the F valve. The H valve is an upgrade to the J valve.

I own a VW Golf 1.8T 25th Anniversary. The car is mapped and I put an N75-H valve on, it did work but then I experienced similar problems to yourself. I then tried the J valve and that solved the problem.

Can I ask what remap you are running?

If you would like a J valve, just let me know and we can see what we can do for you.

Kind regards
Andy

its sounds like he might be willing to swap for a J...if so, go for it.

Could you ask jabba to adust your map to suit the H...?

 

[p34ch3y]

ive asked him if a swap would be ok, havent herd back from him yet

thats another idear i was thinking mate

 

[thewiizard]

that makes the most sense out of any description so far,

F-Valve --> J-Valve --> H-Valve

J-Valve it is, until i start forcing 20PSI through its nose

 

[p34ch3y]

im hitting 20psi an haveing issues with the H so im trying for the J now

 

[rogers]

wot is on a standard engine? iv never changed mine, running apr stage 2 so wot should i go for......

 

[JIMYU]

standard will be a c or an f. i'd probably try a j if i was you but not all cars like those eiter. it seems n75's are a bit of a gamble

 

[rogers]

saw a link to vagparts for a j valve do u know wot it is?

so is there a difference between the j valve and the race valve?

 

[DaNnY_LaD]

Im getting surging problems with mine at the mo...Its holding at around 11-13psi @ 4krpm and hits at 21psi.
But it does surge a fair amount...

Can the ECS N75 Solve this,,?

I have jabbasport stage 1

The 'J' is an upgrade to the standard valve and the 'H' is an upgrade to the 'J' valve. I think?

 

[p34ch3y]

ive just asked the bloke about a J causeing limp mode because every one seems to think it dos and this is what he said


No mate, a J valve is used to oversome the usual limp mode that may occur with the F valve. You will not get limp mode with either the J or the H valve.

People use the H valve instead of the J valve as it holds a lot more boost and can give an extra 2-3psi but is only worth it when running very high boost.

Hope this helps.

Kind regards

Well thats not 100% true is it as we know if you fit the J valve it can cause boost issues and limp mode. People have experience of it on here.

 

[nogutsnoglory]

how high is high boost? i think im running boost 8 timing 7 on revo stage 2, would it be worth it?
