FWIW, the A10 ZL1 weighs 3,925 lbs with a 54/46 front/rear weight distribution (M6 is slightly lighter than the A10, but not much, with the same distribution). The SS 1LE referenced above weighs 3,735 lbs and is 53/47 or 54/46 front/rear depending on the test. So, in reality, the weight is essentially distributed the same in the ZL1 and in the SS 1LE, the ZL1 just has 180-190 more lbs to carry around.

Amazingly, the GT350R, despite being 200 lbs lighter than the ZL1 and obviously without a S/C, is also 54/46.

CURB WEIGHT ZL1: 3,912 lb GT350R 3,713 lb
WEIGHT DIST, F/R 54/46% 54/46%

For further comparison, the base GT500 is 4,171 lbs and 56/44.

GM did a better job with weight distribution.

I'm certain the 6th gen ZL1 has much better intercooling than the 5th gen, which helps w/ the consistency.

Maybe that's why you are driving a ZL1.


Yes I agree that the Mustang exhaust sounds better.

I significantly upgraded the cooling in my gen5 and still didn't care for it. Pictures here of the big Lingenfelter cooler, compared to OE, and Rotofab reservoir.

The LT4's 1.7L blower has a 3.1:1 drive ratio ...to small and fast IMO. The LSA's 1.9L had a 2.6:1 drive ratio. Both generate 9 psi boost.

The ZR1's LT5 has a proper 2.6L blower with a 2.4:1 drive ratio generating 9.4-14 psi boost. That's a nice setup.

I'm good with the power of the LT1, naturally asperated, with an manual. You can still drive it hard on the street and is adequate for the weight of the car. 12.3 sec 1/4 and 0-60 in 4.1 sec is fine.

FOMOCO in all their Mustang products always has to compensate their old chassis design with providing wider expensier track tires in order to be able to perform: Mustang GT PP2, '19 Shelby GT350, Shelby GT350R, Shelby GT500 CFTP and now the Mach1 track package, all of them have Michelin R compound cup tires, that on a DD if bad weather is present (rain or cold) they would be hazardous to drive on them, tramlining present on road groves and their tire lifespan would be very short besides being very expensive to replace them. The Camaro SS1LE and ZL1 ride on just GY Summer extreme tires that perform greatly in all type of weather, street or track, would last longer and with no tramlining on the road for less $. GM couldn't make it better for us, Camaro 6th gen is the best handling sport car for the $ thanks to its design, not just for its tires compounds.

Its amazing that Ford has made so many variations (attempts) and the old SS 1LE still stands up. Chevy isn't even competing anymore and is still relevant.

Cool pics.

The LT4 blower is spinning faster, but the LT4 heat exchangers (HEXs) have a higher cooling capacity than the LSA HEX. For comparison, the LT4 intercooler HEXs have about 10% higher cooling capacity than the LS9 in the C6 ZR1, despite being physically smaller. They are simply a more efficient HEX design (internal ribs to cause turbulence increasing the heat transfer capability). As far as supercharger heat...for any blower (whether on a car or in an industrial facility), the heat of compression is what causes the charge air temperature to increase (heat added to the air stream), which is typically 10-20 deg F per pound of boost, depending on the blower efficiency. So, if both the LT4 and LSA blower are producing about 9 lbs of boost (slightly over for the LT4, not sure on the LSA), the heat increase on the charge air will be directly related to the efficiency of the rotors and blower assembly. The Eaton 1.74L rotors in the LT4 is more efficient than the LSA blower's rotors, so at the same boost pressure the LT4 will be making less heat due to compression.

That said, the HEXs are sized for the stock conditions for a given ambient air temperature. Once the rotors are spinning faster, most boost is being made and thus, more heat (obviously). Also, spinning the rotors faster may decrease the efficiency (I'm not certain on that but it's possible), and thus even more heat on top of the extra boost, compounding the heat issue.

Anyway, just some HEX 101 for the group...

But...but...but Camaro sales suck and nobody wants one and they have to be discounted and you can't see out them...

Are you talking about the 1LE? Depending on the tests, the LT1 engine is 0-60 3.9 seconds and 1/4 mile 11.9


Car and Driver got 3.9 seconds out of the 2019 Camaro 2SS

Yes. I was referring to 1LE M6 test I had seen in the past. I hadn't seen the C&D test you reference. Is this the one? 0-60 in 3.9, 12.2 in the 1/4

https://www.caranddriver.com/reviews...y-the-numbers/

I personally ran a best of 12.2 sec at 116.4 mph in my 16 2SS A8. It would easily run consistent 12.2 to 12.3.

You have to admit that the Camaro’s styling is a bit ...masculine. That can be intimidating to some. And if your daily ride is a mini van with captain seats, the Camaro’s cockpit layout may feel ...frightening.

The best endorsement is this man. Randy Pobst drives a 1LE every day.

It's like pulling teeth tryna get a laugh in here you guys, haha!! Geez...

The point I was soo desperately trying to make is that the 6th Gen Camaro has been soo awesome in everything that the opposition had to resort to fishing for any silly excuse they could find to discredit it despite the performance it comes with. I remember back when someone stated that they think the V6-1LE could beat the non-PP GT around a track. That is how good it is. The way I see it is that GM poured a lot into the frame/chassis of the Camaro while Ford just tried to work around the lazy chassis they had back in 05. And then you have the Vettes out there pushing things even further. Imagine how things will go when the C8 Z06 shows up and destroys everything Dodge and Ford has to offer. And then imagine the leaps and bounds that the 7th Gen Camaros will have...if there is one...which I think there will be. I mean, the fact that GM hasn't even touched the ZL1 since it was released means that all this time has been spent slowly developing the next thing!! I can only imagine!!

I'm surprised that Randy chose a 4 cyl Turbo 1LE for himself instead of a SS1LE.

He said he wanted the driving dynamic. The SS power would get him in trouble.

I thought it was a V6 ...but IDK how to tell the difference between it and the turbo.
