That being said, he also kind of agreed with you: "So in that essence, torque is killing it." You saying torque kills motors is like saying fatness kills fat people. No, it's the fact that a human heart can't support 250lbs of extra weight. In the same way, yah, you could say torque kills these motors, but it's really the sudden onset of a lot of cylinder pressure at low rpms that kills the motor. This pressure subsequently generates torque, but the torque itself is not what's killing the motor. In the same vein, you saying that a bigger turbo will make more boost is sorta true, but it's not really. On a log, you'll see more boost in the upper rpms, which can fool you into thinking it's making more boost, but that's only because the bigger turbo is remaining efficient where the stock one becomes inefficient. ilivas also didn't flat out call anyone wrong, he just said he can't understand how a rod bolt could be damaged by a lot of low rpm torque, not that it doesn't happen.

Yes, but how far along would the medical community be if we just went along satisfied with saying that fatness kills fat people and never dug deeper to find out why? Sorry to use such a crude analogy but it works, and I think you get my point... if he just came on here to brag about his Corvette or something I'd get it, but relating his experience on that platform to this platform is often helpful, at least I think so.

That's pretty much the recipe for a blown track motor on quite a few before they started building them. Then everyone redid the con rods/bolts and custom oil sump pickups to make up for this issue. As for the overboosting, it's all from JB4. Piggybacks cannot react fast enough to save this engine from failure once that occurs. Events were almost always the same: boost to 25psi+ and cylinder blew due to a ring failure. Not saying that it will always boost but due to the lean conditions that JB4 runs the car in plus that overboost... yeah.

While I’m new to this platform, I try to use things that I know apply to all cars. I have been bringing up my Vette because it’s something that I’ve been heavily involved in right now since I’m in the middle of a build. But the concepts should apply.
I do concede that they are not the same car though and not EVERYTHING applies which is why I ask questions as well. I do like to remain skeptical mainly because the aftermarket support of this car is so limited and not many are going past FBO. I do have a large car community here and have learned to respect all cars and I try to get a good understanding of the popular platforms especially. |

Lol! I would configure the safety down to 24psi and cross your fingers.
