Carnage at the dyno... need some advice

[2toneregal]

Most of it is in my signature. But basically, it is a standard 109 block with steel crank, fully studded/girdled bottom end, J&E Pistons, K1 Rods, Bored .030 over. It has a custom ground roller cam by Don Cruz (he wont' tell me the specs on it but I know it's a good one). It has roller lifters and 1.55 T&D Roller rockers, Champion head with the Champion port matched intake. The turbo, injectors, and the rest of the mods are in my signature. Hope this helps.

I was using the mobile app at the time but sounds like a good combo...

Thanks, It's taken my three years to get the car the way I want it. After I replace the transmission and drive shaft, I think I'll be done for a while... I hope

I've installed the driveshaft and Jason White built the transmission. We were driving it back from Jason's house in Mississippi to Florida, got about 50 miles from home and broke the timing chain . Highway speed, 2500 RPM, 60mph... Wonder what damage that did... . I guess it could've been worse. It could've broke the timing chain in the Mobile, AL tunnel...

WOW !! You sure have some shitty luck! Sorry to hear about this new issue but wondering, what brand of timing chain did you break? Oh! I have a carbon fiber drive shaft in my GN.

Sounds like you were in the FWB area, or on I10 Crestview, got some local help here if you need it.
GN owners, trucks and trailers that can be rounded up, I imagine you have the rollmaster chain setup from your build data, that shold not have broken, hope it is not something else like a crank snout etc.

Yeah, I was actually in the Freeport area, just up HWY 331 from HWY 20. I appreciate the offer, if you guys are close by we need to get together sometime. There's about 6 of us here that drive them regularly (exept me lately...lol). When we went to pick it up, we towed a car hauler with us just in case. So, it wasn't that bad. I talked to Don Cruz about it yesterday and he was baffled at how it broke either, especially at just cruising down the highway at 60mph. If you look down the cam sensor hole, you can see the broken link so I don't know. I don't think it's the crank because you can turn the balancer nut and the flexplate will spin as well so it's working all the way through the motor. He wants me to pull the motor and bring it to him so I'm going to pull it this week and try to get it down to him in the next couple of weeks. I got to hand it to the people on this forum. The only thing that makes this whole car worth keeping right now is the members of this forum and those members that stand behind their work. I've never dealt with such a great group of people.
