Cupra 290

[DanielQ88]

Morning all

This topic may have been covered before i dont quite understand the on board psi boost if i accelerate harder ive got it to go up to 26.7psi surely this isnt correct for a stock car , dealer has assured n me its stock

The EA888 gen 3 from an S3 has charge pressures listed at 17.4psi (1.2bar) - so a stock 290 should be around this I would suggest.
Boost pressure can be read in two different ways - relative or absolute - how does your gauge read?

Though your 26.7psi seems to align with google for a remapped car!

Its just the on board psi so im sure this would be absolute

Leon MK3 290 - how many bars of boost should I see on a stock car?

Hi guys, quick question, I’ve just purchased a seat Leon cupra 290 and I do not think it’s stock. When looking at the Sports display I saw upwards of 2.15 bar of boost being generated. I read online this number may be stock as it takes into account atmospheric pressure however if anybody could...

Its probably with ambient pressure included, so you need to subtract about 0.9 bar (13 psi). I remember seeing a high value there with my unmapped 280. To be honest I never used those gauges again after I added a separate boost gauge, which purely reads out boost pressure.

Yea i googled and the inbuilt one on screen is with ambient included

That looks like a nice bit of kit mate

It is! Not everyone likes the look of a turbo gauge, but I love it

I gave my some boot to the floor treatment earlier come up with 36.7 psi reading now i no you have to minus 14.7 or so thats 22psi is that stock readings im new to all of this always had old man cars lol
