We have discussed this on these boards numerous times and my car is still running w/ sleeves when others said they would fail. Running the car on the street, track events, extremely hot summer days, and multiple dyno passes to count for. Never a overheat, coolant puking or headlift so Im happy. Can't speak for the others that have had these issues, with no true fix for the problem other than band aid repairs. Vinny and his team must have the issue down packed, and good for them as they have been working with this platforms at all H.P levels, and different driving conditions to figure it out. Whomever decides to come to the dyno shoot out will see my car there for verification, as Im sure I will Turn the Boost up!

^you have the JWT 850 kit correct?
