Must have the prime..... eeeryone has the prime..... the prime....mmmmm

don’t mind me....

Prime is life! Nothing is better than ordering something around lunch at work. Get home at 530 and bam its already there!

I do. Well, Jenn has Prime. I just use her login info to buy stuff. I think she has Prime Video, if that's what's needed. I'll have to get her to turn the TV on and pull it up so I can see what we even have.

Yep use prime video and search the motor trend channel or something like that. Its weird because if I go directly to the motor and website it doesn't work but through prime all is possible

I'll have to give this a shot. I know I've watched a quite few shows on Motortrend TV, but I never know how to find them with all the damned apps Jenn has and uses.

So back when my spring broke and dropped a valve a buddy offered to have me send him a few and he would test them to identify which model spring they were since I truly didn't know and don't like to spread misinformation. The test results just came back here is what he said.

"Finally had them tested. Looks like they were PAC 1219 and not 1218

They have a 120Lbs. of seat pressure at 1.8 installed height. At 1.3 Height they are 280lbs

The PAC1219 are rated at 340Lbs per inch so that is 170Lbs for 1/2 inch. So 120 + 170 = 290. Being 10lbs lower is acceptable for a used spring and would be considered within spec.

The 1218 are rated at 313Lbs per inch which would be 156Lbs for 1/2 inch So 120 + 156 = 276. The springs wouldn't test higher than they are rated for especially after being used.

1 of the 3 Springs you sent had some odd wear on the top retainer area. Where they just stock OEM retainers? Did they have a locator underneath or did they sit on the hat of a valve seal?"

They were indeed on stock retainers however the spring did not break on a coil directly touching the retainer. Either way this should be a decent thing to consider for people wanting to run high lift cams with single springs even if the spring is rated to that lift.

The BTR stage 3 is what your running right? Its around .550/.550 lift which is well within spec for a set of behives. Also I believe there was a manufacturing issue with the set of PACs I had fail. Hopefully BTR doesn't use the same springs. Either way I wouldn't worry to much I did get over 30k on those springs which is pretty good for anything modified.

Another rescue mission in the Tahoe. My little sister turned left on a green light, not a green arrow and pulled right out in front of a 2019 Jetta going 60mph, totalling both cars but the drivers had no injuries. She didn't have collision insurance since its a $1,500 beater so I had to go pick the car up before we racked up any more $35 a day storage fees. Trailer worked great, the harbour freight 12k winch is amazing and the Tahoe pulled it without any drama, I think its about to roll over 260k too which is cool.




Check out my Japanese lawn ornament. It can be yours for a couple hundo$$$:jester:

Oh yeah, could have been much worse! Maybe it will teach her to look harder and think twice before jumping out in front of someone. I think I can salvage some stuff off it to get some cash back and put it towards another one.

I don't think I'm that bad about high RPM I typically shift around 2,200 rpm. Although when I first got it the rev limiter was set really high I think above 7k and I rang it out a little too far a few times on accident. The failure was at idle so I doubt any high rpm caused a fracture I drove nearly 20 miles that morning gently putting to work before it failed.
