I recently purchased a 1.8T from a 2003 VW GTI with 65K to drop into my Jetta race car. I started to do a leak down test on it, but stopped after a bad result on the first cylinder. The problem is that the engine is cold and dry , so i don't expect to see 2-5% numbers. What would be good numbers on a cold and dry motor? I've also read that the ring gaps on turbo motors are wider and the leak down numbers will be a little higher. Is that true?

Thanks in advance, Mark
