Wow, thrashed it up pretty nice… I’m completely unfamiliar with volkswagons, is that a stock turbo that has had some work done to get it to 20psi, or aftermarket, etc? Any work done to the bottom end or anything before it blew? ---

Any work done to the bottom end or anything before it blew? my stock turdbo pushes 20 all day… not an issue… they are tiny turbos… although, he was pushing a t3t4 50trim? dont remember… but you figure he was a solid 300+whp and was pushing it. bottom end was stock… there are motors running 400+ on stock bottoms, but then again, he drives the hell outta his… still don’t know what happened… we’ll figure that out soon enough. eric: he was running the revo big turbo software for a tseries… what i was thinking is that he was putting load on the car uphill when it popped… so my guess was the fact that the revo software is written for 440’s but also maxxes them… so you figure going uphill high boost on a maxxed injector can’t be the best situation… still dunno though. ---

my theory is oil issue… as dont see rods go w/ fuel issues–pistons go w/ fuel, rods w/ oil. so uphill, blocked pickup tube, motor under laod, rod= bye bye. will see when tore down. ---
