Well We knew it was to good to last

We got the new RPS tripple disc Street Slayer Clutch installed and my friend just finished the 500 mile break in on the clutch but there will be no runs at the strip any time soon. Today on the way back from lunch with less than 100Yard till his parking spot the engine started knocking. We knew she was never going to live at this power level and had already started making plans for a LSX with a 4 leter supercharger but we thought she would die at the track not in the parking lot. So today Brandon got to join the " wrecked an engine with less then 10k on the odo".

I told him to cheer up and not look at it as a loss because now the gloves come off and we can put a real monster in the car.

With so many CTS-V owners in the 700s with no issues I'm scratching my head on this one.

The car has made as high as 752 and as low as 728 RWHP and it has been otwo different dynes many times now. It has never sprayed nitrous through the inner cooler while on the dyno.

The car is going to the shop tomorrow morning and there will not be much to see because it is just rod knocking.

The problems we had where with traction control and torque management, as far as air fuel ratio, timing, fuel trims, that was all great.

The car has been at LMR and Power Fab, it has been on both Dynos.


We had issues with all the different torque management systems pulling timing and controlling the throttle body blades. Before we got it all figured out the clutch burned up and we had to wait for a new clutch. We just got the new clutch last week and they wanted a 500 mile break in before we went back to the track.

Like I said before we new that we where pushing the factory internals and that they would not last long but we figured we would get enough time to at least get the new motor built.

For a new engine we are looking at the LSX but that new 502ci LS block is also pretty exciting. 502 LS-sleeved and stroked

Strange that the rod started knocking during a 500 mile break in period where it wasn't being run hard.

I guess the silver lining is it will be bullet proof when you're done. Can't wait to follow this build.

Yes I would agree back in the day but I myself have been snake bit by the LS3. My C6 had 2000 miles on the odo when it let go. I had a cam, stall, exhaust, and tune so it was out of warranty. I ran it that Friday at the track with no issues and I scanned each run with HP tuner. The car was 100% perfect and the next day was my birthday. Several people asked to go for a ride and I got on it a couple times with zero issues. Later that day my cousin asked to drive the car so we took it out to the hwy and at about 55mph he asked if he could get on it a little, I said sure and when he hit the gas it sounded like I hit a sack of gravel. He almost put the car in the ditch because of all the oil under the tires. It sent a piston and rod out the side of the block above the starter, I have pictures of all the damage. The engine was a total loss and from that point on I don't trust the factory internals at all. Why on earth it let go is a total mystery to me, why didn't it blow at the track or when I stomped it? It even sent metal up through the intake and puked oil out of my cold air intake. You would expect to see this kind of damage from a high RPM failure not a 55mph roll into the power.

I know it's a huge shot in the dark but I wonder if the knocking is from a broken or loose flywheel??? They sound a lot alike and sometimes you can't tell until you drop the trans.

I had my timing chain snap after a cam install. I wonder if it was that? My first sign was a ticking, then the engine shut down on it's own. I had 4,200 miles on it. We replaced the chain (and a lot of other parts) with a Katech c5-R and an LS2 Dampener
