Not saying everyone agrees with this....but it IS in there

Interesting, as Randy Pobst makes a mention of the car being sluggish regarding high RMPS during his Motor Trend run at Laguna Seca during which he beats Z/28 lap time. He blames tall gearing, but I don't think this is the case. Any official feedback from team Camaro on this? Anyone else experiencing the same behaviour? Could it be a programmed safe guard for a break in period? Given rear end ratio and LT1 power levels the RMPS should have zero issues getting to red line very quickly.

I had no problem on track with mine, well, till it stopped working at 1,649 miles. BUT, I followed the Chevy manual to the letter and generally observe this with breaking in any motor. It screamed up to 6k with no problem. I also SUSPECT that the brain keeps you from the high revs during the first 1,500 miles but have no clue.

I test drove a brand new 1LE yesterday and loved the car. Recently sold my 2014 1LE and was looking to replace it with a new one. Everything about the car felt better then my 2014 except one thing. When I was accelerating to run it through the gears just to get a feel for the power, I noticed when the car reached about 5500 rpm that it seemed that the electronics were retarding the ignition and was losing power instead of accelerating right up to red line. I noticed this every time I attempted it. The car was in track mode, the weather was about 68 degrees and the tires were not slipping.

Is this normal? Did I have it in the wrong mode? My plan is to track this car on a regular basis so I need to know if I was doing something wrong or if there is a potential problem with this car. I test drove a 50th anniversary SS a few months back and didn't notice this behavior. My 2014 had no issues pulling straight to redline.

Thanks for any information.

I've never noticed anything like that with my car. But I also wasn't doing 6000 rpm pulls with 10 miles on the car. So I mean there could be some sort of protection set up until a certain mileage is reached? What gear/gears was it doing this in?

But also remember peak power is made around 5500-6000 rpm, so if you push it past that, you really can't expect to feel gobs of power.

I have seen features on GM cars where you can apply teen driver settings but I have never used it or know exactly what it does. Maybe it sets the rpms or speed settings...maybe that was on??? Shot in the dark and probably wrong but I have no idea.

Don't know since my car is 3.5 hrs away and I'm waiting, not patiently, for it!

Based on what I have seen of the factory calibration and what the teams at HP Tuners and EFILive have seen, there is no stepped/ramped calibration that is triggered by time or mileage in the OEM calibration.

Then it appears there's something "goofy" going on here as the poster's comments pretty much mirror those of Pobst. I sure would like to know why that is. Ditto on Vintage's motor failure re: cause. BTW Camaro LT1s are not exactly the same as the ones in the Vettes, yet some folks are saying "99% the same" etc. There are some major differences between the two (that GM has officially stated) including oiling (wet sump vs "semi" dry) and oil return design, which is very different. I am not suggesting this is better or worse, just saying even according to GM the motor has been re-engineered by "20%". Hence it really is NOT the same motor. Not in my book anyway

Edit: BTW going to test drive a Camaro tomorrow. Like the 1LE a lot. Wish it was much, much lighter though (especially given its intended use).

it was probably spinning the tires, that is what mine did initially and with the traction control and how these cars are setup you cant feel it sometimes and especially if you were not familiar with the car.

I'm sorry this thread is nuts!!! Let's get it straight.

Randy Pobst has mentioned the exact same things about the Cayman GT4 because it too has tall gearing. There is ZERO issue with this car's engine management system!

Any fool who beats the hell out of the car on their test drive and complains about High RPM issues before the car even has 10 miles on it is asking for engine issues!

Not sure why anyone needs to do redline pulls in a stock LT1 to make a decision on buying a 1LE or not. The 1LE is all about handling not drag racing! If you insist on feeling the car out at redline go rent a Camaro SS and beat it to death.

People like you are exactly why I will never buy a performance car without ordering it directly and knowing that no one else but me test drove it.

Then stay away from my car when it's on the used market.

I've owned several LS-engined cars from new. Built and re-built several engines both for street and racing (road racing). And was sponsored for racing by the pre-eminent LS build shop of its era, Thunder Racing (who, despite their accounting troubles, no one will dispute was one of the top-3 LS engine builders and designers of their time).

Every time, I drove the car HARDEST during break-in. The reason is to properly seat the rings and wear the cylinder walls. Are you at greater risk of breaking the car this way? Sure. Probably marginal, but let's say it's even 5% greater change (meaning, 1-in-20 people blow their motor). It's under warranty. You can get it replaced free-of-charge.

But, if you DON'T do this, you are virtually guaranteeing problems down the road. Not necessarily reliability problems, but problems where you aren't getting as good of a ring seal, meaning your compression will be lower by a few points. This translates to less power when you have 50k, 75k, or 100k miles. It also means more oil consumption, dirtier oil, and a host of other gremlins.

The people who write those books aren't engineers. They are lawyers, risk managers, and marketing people. If you want to find out how to break in a new engine, call a race shop. Not someplace like Lingenfelter (though they are really great, too). I mean a place that JUST builds race motors. As in, motors without a warranty. Ask them how they break in a motor. It's roughly the same as breaking in race tires or brakes. Do a few things at first on the easy-side of things, then run the damn thing HARD.

When did Pobst ever mention anything like the OP did? Only "negative" things he said was that the throttle was too sensitive in track mode for his taste and that he thought the gearing was a little taller then he would prefer.

FYI, only Z51/GS LT1's are dry sump...pretty much all the base Corvette to Camaro LT1 changes are just exhaust and accessory related.

I think it was the opposite, it was probably trying to spin it's tires (OP is in Jersey, pretty cold there now), and what he felt was the traction control kicking in and pulling timing.

That's what I meant, it was the traction management
