Wish it was smaller. Seen a couple on the track and they have power, but they are bigger than you would expect. What happened to small compact sports cars.

I ran a 1:38 on worn street tires at Pacific with this engine on my first track day in my Z06. On R-Comps and with practice, there's atleast 4-5 seconds to be gained. the LS7 engine is one of the most amazing engines I've ever owned! Extremely linear and predictable at the track, monster torque and power that is always there. At WOT, you'd better hold on because that torque wave hits you hard! I had to manage my throttle very carefully at the track and there were only 2-3 places where I could dare go WOT. The event I attended was the proformance afternoon lapping and as its open lapping, I went and lapped for about one hour straight and the engine coolant temp never got over 195F and engine oil never over 235!! Yes the Z06 is much lighter but the new Z28 is the real deal - conceptually very similar to the Z06. its going to be an amazing car with a monster engine, sticky tires, awesome brakes, great suspension and lots of cooling.. I think its a great deal for a HPDE driver looking for a turnkey track car fully under warranty. Requires no mods to go crazy fast. Last edited by w00tw00t; 03-26-2014 at 08:38 AM.. |

How good are Holden compared to your typical GM? Well in 2000 Car UK took a 402hp HSV GTS around the Nurburgring and it lapped faster than the current CTS-Vsport. Even Car and Driver had this to say when it tested the 2000 GTS. Quote:

But the rest of the story is that the 7-liter Vette/Z28 motor is slightly more compact overall than the 4-liter V8 in the last M3, and weighs just about the same as the 414 HP Bimmer motor. So installed in an E9X chassis, the Z06 motor would be a killer, performance-wise, and with 15/24 EPA mileage in the Vette, would likely be a little better on gas as well. The 7-liter Euro motor would be a fair bit bigger and heavier than the Z06 powerplant. It's basically all in the heads. |

I think you make size more important than it really is. Either engine dissappears in the engine bay of an E90 sized car. Look at the positively huge sedans that Chevy installs LS engines in - wouldn't make a lick of difference of the engine had overhead cams or not. Just as it wouldn't make a difference in the Vette. And if they supercharge/intercool it in the Z06, then the weight and size issue are pretty much irrelevant. So the main reason they extracted power via supercharging is because it's an easier solution, not because it's better. Just my opinion. I'll also be curious to see if Chevy has a problem in their hand with the Stingray engine - if there will be more track engine failures like the one at C&D lightning lap, or if that was just an isolated incident.

By all means, although that wasn't the topic of that reply. I continue to enjoy my S65 on track, so what.
Quote:
In the case of the LS7 vs say the S65, the weight difference is what, 20-30 lbs at most. We're talking minute amounts compared to the overall weight of the car. That doesn't mean people should stop enjoying it, I simply disagree about it being some sort of world class engineering. And it's my personal opinion of course, I don't begrudge anybody their car choice.

I get that! But it doesn't take away from the fact that you can create a phonemonal track car that has extra weight on it. Looking forward to what chevrolet does with the gen6 camaro. Should have a solid 300 lb weight reduction. I'm trying as hard as I can to hold out for that one! |

There was a guy with an LS Miata on the forums. Full hardtop aero conversion, ramped up LS (not sure which), the whole nine yards.
I'm not sure my driving skills are up for something like this, not even close.

Topic 1: A 20-30lbs difference in engine weight (which is the difference between the S65 and the LS7) means absolutely nothing in the context of a 3500 lbs car. Literally it is not measurable performance wise. Topic 2: despite the advantageous construction of the C7, using aluminum this, CF that and a super duper lightweight engine, it weighs only 50lbs less than a 4 seat coupe. In the context of a conversation where less weight means more performance, this is not very impressive. Or perhaps the M4's weight achievement should be given more credit.

Yeah me either yet. Gonna continue to develop my e46, lowering the weight and upping the power as I go.
