I got a great deal for this 2013 on here from the generous member here Swexlin.
Coincidentally it's the same exact car I started with for my current track car (Red 2013 Track Pack car)
My current track car is the fastest naturally aspirated Time Attack car in the country, maybe the world? But at tracks like COTA, the turbo big boys were over 20mph faster than me on the straights with WAY more aero and drag. I am choosing to have the car built locally with my shop UMS Tuning https://www.umstuning.com/
The owner runs most of the Global Time Attack/Super Lap Battle events I go to. We aren't concentrating on power like the Turbo Gods Nth Moto and Calvo, but more on just seeing how much we can run and keep cool in a road racing environment. I think 1200whp would win Super Lap Battle at this point, but every year the LYFE GTR just gets faster and faster so we'll see.
Before we gut and cage the car, going to put the ACR aero on (Thanks to Doug Shelby & Extreme Supercars), ACR brakes and then the turbos and just see if it works the way I want it to. Who knows maybe I'll hate it. If I like it and it works and is faster than my current car and stays cool for a couple laps, then we'll gut it, cage it, sequential etc.
The car is so nice it's going to be hard when we get to the gutting/cage point. LOL. I'll be selling all the interior, wheels, Stoptech brakes etc soon
Here she is bone stock, she has no idea what she's in for. LOL

Going to be a fun one to follow the build and how it performs. I don't think you will even need that kind of power to make a track monster.. Mild 4-6 lbs of boost should do the trick.

Yeah E85! It sucks to add the extra weight by having to start with double the fuel, swirl tank, lines etc but it's a necessary evil.
In a road racing environment it'll put the power down just fine. The limit won't be traction, just cooling. Most tracks I'll never be under 50mph, most time spent way above 100mph. Lots of huge power RWD time attack cars.

You guys might be forgetting the capabilities a MoTeC system brings to the table. I would bet the final product has loads of mechanical grip, but the ECU will fill in nicely when needed.

I'm curious about braking on this project. 1100rwhp will make for some sketchy speeds on the straights.

Yeah that too. Even without Motec, the factory Bosch traction control is just as good. When I switched to Motec, I had to adjust it to to level 8 (goes from 1 to 10), 10 being the LEAST intrusive. That got me to where the factory Bosch setup was, basically would never slow you down, only make you faster. Brakes are going to be factory ACR CCB's. With my 800whp car, never once felt any fade. There is no better brake system IMO

With boost at that power level, you will be the only car on the track running 93 pump gas. ������

All kidding aside, for what you are doing I'd run race fuel just for the safety factor.

For reference, Nth has been pushing 1300rwhp on 93.

I posted this in another thread, and not trying to hijack, but my factory Bosch system ('13 GTS) is SUPER overactive. Constantly cutting out when not needed at all. I have to turn it off or it get's extremely annoying. There may be something wrong with my car though. Wheel speed sensor problem maybe.

You are talking straight line traction control right? Mine never does this, but I'm also on slicks and never use 1st gear. Does that only happen in 1st? For my system to interfere whatsoever (traction and stability control) I have to really fuck up, or when I hit tall curbing and catch a lot of air, then i'll hear the spark cutoff for a split second.

Any fast or rough upshift that shifts the weight of the car to the rear calls for ignition cut in my car Lol. It's infuriating. Yet it'll let me spin the tires in gear in certain scenarios.

We have seen variances in the OEM modules pertaining to G sensitivity and such - some cars will trip plausibility limitations and simply a module swap makes it go away.

Excessive HP many times can become more of a problem then an asset.
We took a porsche GT3R to button willow for a quick shake down weekend after a big time attack race. GT3R only has 525hp and we were 200lbs heavy because of endurance setup on car. 1:40 best time and we ran 1:41 consistently. Im sure we could have squeezed out 1:39 and probably a 1:38 or 37 if we put a more aggressive qualify setup on car but it was just a quick shakedown day for us. The big trick in any type of motorsports is , (and this is an extremely encompassing statement) "efficiency of your setup".

That's why we are going to start with the stock motor and just play around and see what happens. If it blows, will send to Prefix for a stout bottom end and heads/cam.
Remember, in one 20 minute road race session, I'll have more high RPM time on it than a street car would do in a year. If you watch my videos I'm basically pinned to redline the entire session.

Those cars are badass, but I could never afford a $600K track car. And I'm only interested in making Viper's faster for the Viper community. Not sure how I can make mine more efficient as it's the lightest Viper in the world as far as I know. Ceramic bearings? I cannot modify the suspension pickup points as per the rules, so there's always that street car compromise.

Spending 600k+ for a properly designed, engineered and built car is just a fast way to get "efficiency of setup". Weight is just one part of the formula, a big part for sure but still just one part.

About the only thing "reasonable" left for you to do is have a chassis made from Aluminum. That's a easy 150lb weight loss plus you could do some cool suspension tricks.

The smartest thing to do would be mount the turbo's on the outside of the car like Feras's vette- https://www.instagram.com/feras_qartoumy/
But it won't look good on the Viper IMO, trying to keep it stock looking. And we want to keep the radiator 100% clear, so will mount smaller multiple intercoolers on each side, so will cut into the bumper. We'll see..

If you remember Austin Barnes, he dominated the road course in the Optima Challenge in his Viper. He recently switched to a C6 Corvette so he could get more style points for major modifications (I guess he didn't want to cut up his Viper) and to add power with turbos. The C6 makes about 1100 hp and he mounted the turbos near the back of the car. I'm not real fond of that set-up as it is not quite as thermally efficient, but if you are not trying to make killer power it could have the advantage of better weight distribution. Packaging might be a b....h. Turbos hanging off the front of a motor will put undesirable weight on the nose for road course handling. Feras's set-up is a pretty good compromise.

The only potential problem with mounting the turbos up front like that is the compressor taking damage from FOD. Sand, gravel, etc. For drag racing, not a big deal, but for road racing, I'd be a bit more concerned with it.

Not a huge deal, but something to keep in mind.

That is one sick road race Vette. How does your N/A snake match up to that snailed Vette, lap-time wise?

Looking forward to your new build. Ever thought about aftermarket active aero wing? It would help with braking from 1200hp worth of straight line speed. But.....It will kill the aesthetic of the ACR and none of the retrofitted active wings I've seen look good or match the Vipers looks. Too bad someone couldn't rig the ACR stock wing to be active aero. I'm sure some cleaver engineers like DSE et al could do it if it made financial sense.

I don't know Cable -- I think you could leave the stock outer panel in place and route the exhaust into side pipes in the stock tunnels. It would require moving some stuff around (like the ECU), but is doable. Would have to make some provision for the waste gate and perhaps duct some cooling air into the area plus heat shielding on the inside of the panel. Looks like he used pie cut titanium to fabricate the exhaust much like my son did on the Lambo project.

That's a good idea Pappy, you won't get as much cooling effect though.

A lot of folks put thermal blankets around the turbos to keep the heat in - makes them more efficient to a small degree. The cooling you would need would just be to keep the heat from building up around the turbos and damaging other components. The way the side scoops are built, they would be a great air exit with low pressure behind the scoops. It might not hurt to direct a little cooling air toward the turbos with air hose from the front of the car, and you would like cooler air near the turbos inlet if possible. I like the idea of coming off the turbo exit right into a 4" side pipe in the side pod - would be very efficient.

BTW, G-Speed is big on removing the back of the front fender tub and the body panels behind the front tire to extract air from the wheel well for aero. The ACR does a pretty good job of achieving the same effect with the fender vents above the tire.

Both amazing companies, but we are going to be developing this for the track, on track. I've got access to a local track close by the shop. We are concentrating on cooling moreso then power. Power will be easy, it's the cooling that will be hard. Doing a few laps on a track is like doing non stop half mile runs back to back. The shop I'm using is very capable with motec and turbo's etc, it's what they do.

A possibility would be mounting the turbo "mid-ship". The slight lag that "might" be created would probably be minimized when using an sequential or air shifted trans. Also keeps ALOT of heat out of the engine bay. The mounting place is under the car near he fuel take. This "sounds bad" but really isn't. You can't ask for a better place for the added weight and heat. Depending on how creative you are willing to get I have some interesting ideas for the intercooler.

But I thought that I had seen Viper installs behind the front wheels also. I thought it was very low, nearly impossible to see from overhead. It would have been a Florida car (a yellow Gen V GTS). Was I dreaming this up (not the car, but the location that they used)?

Take a look at this link. The car - the Juggernaut - has the turbos mounted on each side of the motor with the exhaust going into the side pipes. I think the turbos could be moved back and outboard a little to get the heat a little further from the motor and to provide more room for big front tires. The air being pulled out the side vents past the turbo bodies should help with moving hot air out. Aluminum heat shields between the motor and the turbos would also help. I wouldn't want to be around when you see how much the extra tubing for rear mounted turbos weighs - I'm not that good with CPR. LOL

The air being pulled out the side vents past the turbo bodies should help with moving hot air out. Aluminum heat shields between the motor and the turbos would also help. I wouldn't want to be around when you see how much the extra tubing for rear mounted turbos weighs - I'm not that good with CPR. LOL

LMAO on the weight!
Yeah, that setup is badass, gonna show it to Tony. That's my favorite Viper of all time I think! Aaron is an artist.

It kinda goes well with Feras mad max style car. This car is in my class btw.

He just posted a 1:10 on the local MSRC 1.7 mi section... and they're pretty sure it has a 1:06-1:08 in it. I believe the track record is around 1:05 and was set by a prototype car...

It's a little insane to think about the difference in speed compared to what I've done on that track - My GTI does the 1.7 in Spec Miata times (~1:30, LOL!). Hell, even on the 1.3 mi section, I'm still slower running a 1:14 with three different cars: a 458 Italia, a Gen V Viper, and my GTI.

The vette ran a 2.08 at COTA first time out 2nd lap, then had issues. He hit 184mph with 3-4 times the aero drag of my car, so we are talking 1300whp minimum, car has dyno'd 1500whp. He should be getting close to 2.00 flat next year which is what it will take to beat LYFE's GTR. It ran a 2.06 this year coasting through the finish line with broken driveshaft. You can see it here start at 18 minutes. This is one of the most exciting/amazing things I've ever seen in amateur racing- https://www.youtube.com/watch?v=rFib0J2zeH4
If you go to 21.18 you can hear my car going down the front straight right after.

My buddy ran a 105 in a daytona prototype and while he's an insanely good driver in a very fast car, I'm pretty sure open wheels have gone faster. I want to say right around 1 flat.

1:10 is still comically fast

I would hope the proto's have gone faster. Remember, even in unlimited, Global Time Attack cars have rules. Production based and we are not allowed to modify things like suspension geometry. A 3000 pound car can never beat a 1000 lb car around a tight road course, even if you had 10,000 horsepower. COTA yes, normal tracks no.

Daytona has half the aero and less than half the power, lol. It's definitely lighter, but it's nowhere near 1000lbs lol. It's 2300lbs. Heck, just an LS long-block and fluids is around 600lbs.

There's a guy in Cali that runs Nasa unlimited class with a 700whp Ginetta G58 that weighs 2100 and a 240whp Mazda DP02 that weighs 1100 and the Mazda is like 5 seconds faster same driver. Seeing that thing on track in front of you is like watching a time warp. Your brain can't believe what it just saw lol

Yeah they're wild. They can somehow run low 2:11 at COTA with a top speed of like 135 in those huge straights. That's insane given how much it's giving up in straights.

https://www.youtube.com/watch?v=n7xgPUkCVVs Last 2 min for the fastest lap.

Off she goes to UMS Tuning for some boost!!!! Growing up poor it feels really weird chopping up such a nice car. Almost had second thoughts, but didn't. LOL

You know Jordan? He is a hell of a good driver.

Where did you settle on for turbo location? Can't wait to see this thing done.

We are putting one intercooler on each side of the radiator, we didn't want to block the radiator at all... We will also be putting in a huge oil cooler in the rear. The oil tank will also be in the rear

Building my dream car! TT Viper. That Time Attack Corvette setup is nice. I think he said he only gets 3 laps before it starts to pull timing. His build is budget though. How do you cool your turbos?

I too thought that removing the rocker panel would have been the best route. Best would be to have a fiberglass mold done of the rocker panel with a few pieces made to cut up and get the design perfect. You can cut away as much as you need to while still retaining OEM hardware along the sides. The rocker panel is very "wheel well" fastened. Meaning along the center there is barely anything holding it down from the top and bottom.

He gets 1 lap only, then hits 290 oil. Same as all the monster power time attack cars.
Good idea dude! We'll see how this goes! LOL.
