Boost psi?

[jonnie5]

I was in another Leon Cupra tdi today and it had a boost gauge fitted. At nearly 3-4000rpm it was at 1.6bar and spiking to 1.8-1.9 at times. Thats about 21psi is this true or just a gag? I would have thought the tdi would run lower than that?

Think the tdi run at a higher pressure, than petrol.

my old ford tdi ran 2.2 bar peak and 1.9 normal

I suppose that the diesel being to heavy and sluggish that it needs to run higher. What turbo does the 150 have. Any similar to the R?

Total different turbo, diesel and petrol
