Is an LS3 a ticking time bomb at the track?
Many people on the Corvette forum say that it's very foolish to take an LS3 anywhere near a racetrack without a proper dry sump setup. How true is this? Would running a thicker oil, with a baffled oil pan, an oil cooler, accusump and keeping a close eye on oil pressures not be sufficient for the occasional HPDE? I've seen a few videos of C6's literally blowing up on track and it's pretty scary...
This is for a project car that will have an LS3 crate engine running on MoTeC ecu. Car will weigh 3000 lbs with me in it. Car will be used about 70% street, 20% autoX, and 10% track (Laguna and Buttonwillow). Car will have no aero and will not be running tires with more grip than a DOT rcomp like NT01's or R888R's. 275 square will probably be the most tire I'll be able to fit. It's hard to believe with this setup that I'll be able to surpass or even match Corvette levels of grip. I would think I'd see sustained lateral G's slightly over 1G. Maybe 1.2-1.4 G's if I really got it dialed in. I would think running Buttonwillow clockwise I'd be fine as sustained long lefthand turns seem to be the big issue, more worried about running Laguna. As this will mostly be a street car for now I really don't want to give up AC. Eventually when Commufornia decides they will no longer let me drive on the street then the car will be caged and trailered to and and from the track. At that point I'd add dry sump, fuel cell, fire suppression, aero, etc... Car is a 2016 BRZ, so it shouldn't be due for a smog till 2022. Then I'm going to try my luck with my dealers plate. Please save the just go buy a Vette comments. |

The 1LE is a certified track car from the factory and is an LS3. So unless your some pro hot shot on the track the LS3 is an awesome unit

Just say no to thicker Oil FOR #1......the ls is made with 5w30 in mind and its oiling system, and the same jokers who on the Corvette forum say oh this has to be dry sump...do they even drive with Racing oil? I use driven racing ls30 full synthetic oil made for modified ls engines.. they make specific oil for direct injection, forced induction etc I believe in a high volume not high pressure pump as that's whats recommended and its much better pressure also, I also believe talk is cheap and if your not spinning 360's don't worry so much. There is a good aftermarket maker of oil pans that are baffled for the ls3 engine should you desire not to go to dry sump.

Throw in an improved racing crank scraper/baffle while your building. You won’t regret it.

That is a pretty ridiculous statement. A dry sump system is nice but not that many cars have them in the first place. As long as you have a good pan on the car you have nothing to worry about. The LS3 is a great engine and extremely easy to make power with. Should be a killer in a BRZ
