How much power were you making when that happened ? What pulley was it on ?

 

[lx347cd]

that really is sad considering it is bone stock with Whipple supplied tune. Maybe OPG and sprocket install was an issue?
what did Whipple have to say about this?

I can’t say i didn’t have it dynod and it was the a 3.75

They didn’t have much to say other than sorry to hear that. I had an open case with them before that becuase i would do 3 pulls and my cylinder head temp would reach 250deg they said it was normal to see that i never felt good about it but now speaking the the engine builder he thinks that played a big roll. He didn’t find any degree that might have blocked oil to the rods really weird but hopefully after what’s being don’t to this engine i won’t have to worry about that again

Which heat exchanger were you running?

I’m confused, you installed the kit and didn’t take it to a dyno to check out the tune before making WOT runs?

It's going to happen to these motors eventually with boost some happen faster than others it really depends on how lucky you are. Every motor is different and sometimes you get a part that's just good enough to pass the QA and is weak enough to go with a little boost.

At least you caught it before you shot a rod through the block. I'm saving up for a fully sleeved motor after my warranty is up.

Are you going to resleeve the motor?

The stock engine if tuned & fueled correctly should last thousands of miles?

There’s plenty of them out there doing fine. Now if your pushing it (Boost) with improper tuning, or at least checking the tune then your looking for trouble.

Ticking in the head you say?

 

[Stymee]

Ticking in the head you say?

Ahahahaha

 

[DavidHuff]

Ticking in the head you say?

WHY?

 

[sigintel]

What oil? 5w-30 might not be enough if knocking at 250F CHT. Even 5w-50 might not stop the bearing making contact on det.

250F CHT on 91? Uhhhh should have been knocking.

Reische 170, pull the coping, GT350 rad, 4.0 pulley. At least short block is cheap.
Or snag a predator block, pistons, rods?

Yes that’s exactly what’s going on now it’s getting all forged internals, sleeves cylinder, cnc Head porting and studs. Hopefully it will be done within the next 2 weeks

I did not but don’t think that would’ve changed the outcome but i might be wrong. Whipple assured me that was not needed if i was running there stock tune that it would be safe but then again i don’t really believe it was the tune or there product that caused this probably would’ve showed up eventually just the boost accelerated this
