I'm entertaining ordering a new ACR and will track it often. Just wondering what you guys have experienced oil pressure wise on track. Having a wet sump track motor isn't ideal. I'm coming out of the Porsche GT3/2 world and they of course are all dry sump motors. Can this motor handle track days without issue?

Thank you for your time,

Dean

i'm in the same boat as you are, coming from a porsche 997 gt2 and considering getting the new acr for the track. Hopefully it does handle track abuse as i'd love to drive the car on the track and see what it could achieve.

I love seeing all you Porsche guys contemplating the switch to the Viper. You will not be disappointed in your decisions! The Viper is probably one of the most reliable track cars money can buy. I had the pleasure of attending a Viper specific event called the "Viper Experience" in Las Vegas, where we literally beat the shit out of the cars in 90+ degree heat with no breaks for hours at a time and not one of them had a hiccup to speak of. If you search the forums and the net a bit you will see that other than the occasional mishap with a few blown motors, overall the cars are built to withstand some serious abuse. I personally have had about 6-7 track days on mine since owning it and not a concern or issue to speak of, it barely even burns oil! This would be the least of my concerns if I was contemplating a Viper.

The Gen 5 Viper has an 11 quart oil capacity, and utilizes a swing-arm oil pick-up tube that shifts from side to side during cornering. The oil system is simple and reliable, even on Vipers making in excess of 1000 rwhp. Keep in mind that the Viper doesn't use the ultra-high rpm like some of the other brands do, most of the time you'll be in the 4500-5500 rpm range on the track. I find myself using the torque of the engine to exit most corners, especially on technical tracks. Winding the engine out to 6400 rpm is usually just on the straights.

I think you'll find that the Viper is the most durable track car made, they are overbuilt and tough underneath. They also require very little maintenance, and are simple to work on.

Been tracking my 08 Gen IV since 08 and the motor setup is pretty much bullet proof. Have added rear diff and transmission coolers though.

Does your TA have a clear bra? If so, how long does it usually last before getting a new clear bra because of the numerous track days?

Yes, I have full clear bra on the hood and front bumper...and also applied it to the rear bumper as well because of the kick up from the rear tires. My clear bra still looks great, very few marks if any, however, I have gone a little overboard on a few days where I thought there would be more debris and added an extra layer of TracWrap over the top of the clear bra for extra protection. TracWrap is awesome stuff if you are concerned about your paint.

the swing arm setup is a HUGE help. 15w-50 oil and you're good to go. These motors don't turn a ton of RPM's

2014 GTS purchased new last November. It now has 8,000 miles and about ten track days, mostly at Big Willow with its VERY long Turn 2. The car is nuts reliable and runs very cool compared to the 2008 Z06 which was my prior ride. No oil consumption issues either. It's a blast on the track.

Hey Matt, what brand of 15w-50 oil are you running and where do you find it?

You can take what NineBall says to the bank in terms of track behavior or race experience.

I suspect at the track (my experience is limited so, grain of salt here) coming from Porsches the gigantic torque that is essentially instant and is available through the power band will be what seems different. As well as all of this happening at lower rpms. Don't be thrown by seeing lower rpms than you are used to. Lower rpms, but much lower times ; )

Thanks for the response, just something for me to consider. :D

I'm also in the bay, in between Laguna and Sonoma.
