Just a quick question, i was wondering how much boost a stock 6.5l TD can really handle, considering the 21.5:1 compression? Ive heard of heath diesels pushing 22psi of boost with stock pistons, but yet ive also heard of others not being able to handle more than 15psi or so, then breaking crankshafts or destroying pistons when pushed too hard. Just wondering if anyone has any thoughts or info. Ive had mine hitting 15psi with no trailer or weight, and i dont want to do any damage if it builds any more when pulling hard.
