It should be worse!

[Snakebit10]

Wow a TA 1.0 with Levitas suspension was 1 sec faster than an ACR extreme....That's a good test of suspension and tire between the two on this no down force track. That really makes me wonder what an ACR with that suspension would really do. I wish they swapped cars just to see if the gap would be the same thus lessening the driver being most/part of the reason. I really think its the suspension though because Ralph is no joke as a racer.

Last post from me about this on this thread so as not to hijack it any further. Ralph has our active dampers on Storm and loves it.

[AZTVR]

Ralph is very fast, ran Viper Cup and still runs quite often I would put his times up against just about anyone's. .

I remember the Viper cup race video where the introduction displayed the head shots and names of all of the drivers except one. That one just had a helmet/visor-closed shot and a name of Corey Vettsux.

[VENOM V]

Ralph is very fast, ran Viper Cup and still runs quite often I would put his times up against just about anyone's. He was on R7's with the grill inserts removed and the front fender inserts removed. Randy Pobst was in Mikes stock TA with our Active Dampers car was also on R7's. NCM is not a downforce track so not much advantage for the ACR.

The TA on our suspension ran a 1:55 the ACR was in the 1:56's Luke on slicks was in the 1:57's I think.



Lap times

TA 1.0 stock with ViperExchange Active Dampers, R7's, Randy Pobst 1:55
ACR Extreme stock with R7's, Ralph 1:56
TA 1.0 on Pirelli slicks, Luke 1:57 (I don't know much about Lukes car but he posts here)
TA 1.0 Gary W ViperExchange Active Dampers not sure what tire or mods on Gary's car but I'll find out more.

I'll chat with Mike L today and get more specifics about the temps both ambient and what they saw.

That's cooking! And I aint talkin about the engine temps, LOL.

I know you said you've made your last post, but if you do get any specifics on coolant, oil and ambient temps on any of the cars, please post here as it is very relevant.

No C7 Z06's out there to beat the Vipers this weekend, on their home turf?

[lmcgrew79]

Im Luke, TA 1.0 with arrow pcm and high flow cats and slicks. Ill start a new thread ive got piles of great video! Day 2 Randy took my car to a 2.09 on a different config, i ran a 2.11 pretty much inline with day one. We both got around a half second to second penalty for traffic, i also drove Gary's car with the DSC suspension, much more planted than stock, even down the back straight there is a hump that kind throws my car a bit, its ok if your used to it but could be unnerving, garys car with the dsc's felt like it had aero it was so planted, much more confidence inspiring, the car is just much more compliant everywhere.

[serpent]

I won't sell it for a while. My new car will not be in until March April. I am not announcing that to avoid the flames.

No matter what I bring to the track, there is something faster. 2 events ago a guy showed up in Michael Schumacher's 2002 Ferrari F1 car. He passed me and it didn't bother me.

Whatever I drive, I prefer to have the car up on its skis a bit without worrying about the engine blowing. I ran a bunch of races in a spec Miata…not the fastest car, but driving it was a freaking ball.

Yea I was about to respond that there is always someone faster. I know you are a highly experienced and skilled driver, would be bad ass to see what u can do in a stock ACR and see how well you stack up in comparison to the pros like pobst and winkler. Maybe your name will be up there with the viper record holders.

What were your oil, coolant, and Intake Air temps? What was ambient temperature that day? How long was each session?

[lmcgrew79]

Highest oil temp i seen was 270, coolant hit 241 toward the end of day two toward the end of a session following close behind another TA, ambient temps was 60-78 degrees, never looked at iat. Stayed cool day one and most of day two, end of day 2, the car got ran by myself, randy, myself, and then i took out a passenger in another group, so there was a few back to back session. The car seemed to run alot cooler this weekend than in past weekends and the only thing changed on the cars is ive went to high flow cats. This track as alot of 2nd gear turns as well and on ive added a water temp gauge to my smarty cam. Even when i hit 240+ i just keep running and it seemed to be perfectly fine, never made it close to 245-250.

Sorry Randy is simply a better and much faster driver than Ralph imo, to be expected anyway

To the OP, you can see temps in Randy's vid. The ACR will crush the competition with appropriate driver

In factory form yes the ACR will crush the TA. None of these cars ran are in factory form. Giving all equal tires/drivers/hp im not sure they will be as far off as you may think. Depends on which way you look at it.

Brakes and aero account for something, not to mention suspension tuned for the car; don't need hp to substantially faster

Thanks, those temps are pretty consistent with what some of the rest of us have been seeing. I wonder though what temps you would see if it were 90-100 ambient. Also what mods, if any, do you have?

Arrow PCM and High Flow Cats.

How'd you get coolant temp to smartycam? Was there an update? Last I looked it wasn't available.

[FLATOUT]

An ACR with the active dampers will make that car (ACR) faster. It's easy to look like a faster driver when the car isn't fighting you. Much easier to put power down on our dampers. Ralph is a great driver and everyone was on a tire as well so it's not like everyone was out there drifting around the track.

On a tight track like this down force won't make near the difference it will on a bigger circuit. I doubt anyone will argue the benifits of downforce on a high speed track.

[BLUETA#1]

I just notices that I made a major typo…the headline of my post should have read " "It could have been worse." Not "should." I was implying that by buying a Corvette, I would have been in more trouble.

[lmcgrew79]

You can add it from the smarty manager. Make sure you have the updated manager.

[SSGNRDZ_28]

For what it is worth:

The most dramatic thing that happened was this: During our first day of track testing at NCM, the Corvette displayed some engine oil and transmission temperatures that were definitely all the way into the red zone. Some of that is design, and some of that was just due to our decision to have eight drivers in a row take the car out for multiple-lap evaluation runs.You wouldn't ask your own Z06 to endure that many track sessions in a row without a break, and in truth the only one of our eight cars that didn't appear at least occasionally troubled by the demands of our regimen was the Viper ACR. Each of the other cars managed to overheat something, even if it was only the brake fluid.

[TrackAire]

I hadn't read this article, thanks for posting....but in it was a sub article listing the maximum temps for the Z06 that GM recommends:
http://blog.caranddriver.com/fahrenh...06-are-insane/

Look at some of those numbers....I don't know how accurate this article is, but they are claiming the not to exceed coolant temps is 239 degrees. Brake fluid not to exceed 338 degrees (seems kind of low while tracking). This is an interesting chart.

In Grassroots Motorsports magazine they did an article on the Camaro SS as a project car they are building a few months ago. They were pissed at GM because instead of displaying the actual temps for the coolant and oil, GM uses some sort of predictive software to "guesstimate" what the oil and coolant temps may go to and display that number instead of the actual temps.

Who the hell does that?? Maybe this predictive software is actually displaying higher numbers than what the Corvette is actually producing and causing the car to shut down prematurely?? If they're using it on the Camaro, I wouldn't be surprised to find out that it is on the Corvette also.

Cant wait for the results on the track lap part of it. I'm pretty sure the Ferrari or the Merc will win overall. I will be surprised if the ACR doesn't win the lap time battle but that 488 is no joke.

Its worthless to me....I don't have an ACR!

[Bruce H.]

Someone is sure to experience and question higher temps in an ACR and before long the internet will be claiming the ACR overheats on track. Maybe this forum needs a sticky with dozens of links to videos of the various models being flogged around numerous tracks running scorching times with temps in check. Certainly lots of them out there.

I think that with the design differences in the dual splitters (TA) and the ACR's full splitter and sculpted under side, the cooling will be better on the ACR.

I must say, the underside of the ACR including the diffuser design is just as beautiful as the exterior! Amazing work from those guys.
