Increasing boost pressure does much more than you'd think on the surface, but "I figured, if the motor has compression of around 400 - 450 PSi, another 28 - 29 psi wouldnt hurt would it ?" At atmospheric pressure which is 14.7 psi, or 1 bar, we add 2 bar of boost (29.4 psi) to get a manifold pressure of 3 bar, or 44.1 psi absolute (psia).

Extended cranking requires lots of reserve, way more than run of the mill gassers. We also use quite a large battery, bigger than the std. Group 34, probably the most popular battery of all. A lot of people here have sought a 'better' battery for their TDI's, most turn to Interstate or Optima. whitedog. Your boost leak (if it's on the intake side will be between the turbo and the EGR valve. Pull the hose off of the EGR valve, pull the accordian hose off of the pipe to the turbo and plug both of these. Now put air into the PCV port. If I have this all pictured right, this will show you an intake boost leak.

When found in the 1.9 L TDI-PD (BLS): Check vacuum supply from the vacuum reservoir located in the valve cover for leaks. Using a vacuum gauge, wiggle the valve cover and hose connections to check for a leak. The following photo was submitted from a customer working on a 2010 VW Caddy (2K chassis) with this vacuum reservoir problem. New video:

Location. Ohio. TDI. 2000 NB. Oct 7, 2012. #1. Hi, I'm considering a swap from a 2000 Beetle into an 05 Ford F150. I'm not worried about the power aspect, the Ford has the gutless v6 and would be my daily driver for mpg not for real use as a truck. My major concern is bolting the 1.9 up to the m5r2 5 speed.

Re: 1.9 TDi Sportline GTB22 Boost vs RPM. by waynemodz » Wed Jan 21, 2015 8:51 pm. hi, a full log is confidential but i can assure you its done to spec, 78% at 4000 rpm on 4th gear. 80% is the norm but i went 78 because on 5th gear and 6th the it goes to 2 bar, where as running it at 78 and setting the map at 80, solves this issue. You mention on using a turbo from a 1,6td in your 1,9liter engine. I suggest you drop the idea. The 1,6td unit has a turbine housing of a 0,36 ratio. This will make your 1,9 liter engine perform really well from approxiamately 1000rpm to about 3000rpm. Might be great for heavily congested city traffic tho'. .
