My Nth Moto TT GEN5 Viper and half mile results

[racegate]

After having Nth Moto do some work on my old 99 ACR TT and being very pleased with the results, I decided to send them my GEN5 Viper for some go-fast treatment.

Pertinent details:

2015 Viper
Nth Moto Bolt-On Twin Turbo Kit w/ Air-Water IC & RaceTank option
Nth Moto MoTeC GEN5 Viper Package
Nth Moto Triple Carbon Clutch
Nth Moto fuel system w/ Ethanol upgrade
Nth Moto built rear-end and high-strength axles
Stock Engine and TR6060 Transmission
Toyo R888 on the factory 19” SW2 wheels

I sent the car to them in October and it was ready in December, however due to some issues with my transport carrier and some other out-of-scope items not related to their work I wanted to address while it was there, I did not take receipt of the car until the middle of January. The process, communication and experience was first class just like my initial experience with them on my older Viper. I was always kept informed of where things stood, in the detail that I wanted, which kept me comfortable throughout the entire time it was at their facility.

The idea was simple: to build a fun street car with stock like driving characteristics that would do work on 19s. And that’s exactly what was delivered.

Here are some pictures of the final product which testify to the high artisanship of the entire Nth Moto team.

The attention to detail in machining the mounting for the MoTeC wiring harness is one of my favorite aspects of the engine bay. If you didn’t know any better, you would think it’s OEM. That’s exactly the type of fitment I wanted. While its a very minor detail in the grand scheme of things, this is the kind of attention to detail I’ve come to appreciate and expect from Nth Moto.

Engine Bay

The “OEM looking” theme continues in the overall engine bay. I have had folks that weren’t Viper/car enthusiasts think my entire engine bay was stock. The quality and finish of the prominently displayed Nth Moto A/W intercooler is amazing. It’s another piece with OEM looks & fitment which really adds a subtle yet sinister look to the engine bay and most importantly facilitates the requisite charge cooling for my current and future HP needs w/o sacrificing any engine cooling ability.

Water Tank

Completing the A/W Intercooler System is the race tank located in the trunk which allows you to pack the water system with ice to really bring those charge temps down if you desire. I however am pretty lazy, and am not #AboutThatLife, so I just leave it filled with water. Even just leaving water in the tank and not servicing it with ice, the IATs stabilize around 100degF in the Southeast heat and barely climb when driving around on the street and while making back to back pulls. While it's designed to hold a decent amount of water/ice, it does not take up a significant amount of trunk space due to being form fitting into the right rear corner of the trunk cavity.

Boost Control Knob in the Glovebox

Here is how I change boost. 2 settings for Pump Gas (White), 2 settings for Ethanol (Blue). The best part is the entire enclosure is covered in OEM style texture and finish, not some cheap powder coat or paint. Again, the smallest of details making the biggest of difference.

With those features out of the way, now on to the good stuff, power.

On 91 octane and 10psi the car made 1000whp and on E85 and 11.5psi it made 1125whp. We decided to stop there with the boost/power due to the completely factory long block in the car. The car also loses no power anywhere in the RPM band compared to stock. The system on the car is designed in such a way that if/when I’m ready to go to a built motor program the turbos, fuel, clutch, etc are all ready to go and it’s just a matter of turning up the boost. Let’s see how long until I get bored with the current power and decide to build an engine.

Driving Impressions

As great as it is to have a nice HP output, there are certain aspects that are equally important in a street car. How it starts & drives, how the clutch feels & engages, and the power band while just tooling around on the street are all paramount to an enjoyable driving experience, and the car does not disappoint in any of those segments.

Cold Start Video: https://youtu.be/oZGtSoR6gzo

You can see the car fire right up and hold a rock solid idle. If you pay attention, you will also see a very cool feature of the build. When the “+” button is held on the steering wheel, the coolant temp read out changes to Ethanol content! It’s reading off the same sensor the MoTeC uses to do all it’s on the fly tuning changes for Flex Fuel — how cool is that!

The turbo system is so responsive that it makes darting around in traffic really, really fun. No matter what gear and what RPM you are in, it’s “always there” and ready to go when you start applying throttle. This makes it very easy to drive on the street without having to rev the car out at WOT to get moving briskly to pass a car or something like that.

The drivability itself around town is just like stock. Anyone can get in this car and drive it. And with the TC system (which I sometimes turn off for fun ), its is quite safe and predicable even on the higher power settings when hitting the go pedal.

The clutch. The funny thing about the clutch is that when I was first backing the car out of the transporter, I totally forgot the car even had a non-OEM clutch in it! The pedal pressure is very reasonable, the engagement is smooth, and it allows for some very quick shifting when racing.

Now here is a cool story. I took delivery of the car two weeks ago and sent it straight to the fine folks at Shine Auto Salon to detail it and install a clear bra. I got word that a spot had opened up for the WannaGoFast 1/2 mile race in Ocala, FL taking place the following week. So as a last minute decision, I decided to drive the car 500 miles from GA to FL and run in the event. The entire drive down I was taking work related calls on the bluetooth system with the AC blasting and the cruise on. When we got to the track, I put the Ethanol in the car and got it up to E70. First pass out the car ran 185.9. By the end of the day I managed to run 191.8mph in the car, which to date is the fastest recorded speed for a stock motor GEN5 Viper in the 1/2 mi. All of this was done on the 19s. It was so impressive to drive the car that distance, run those numbers, and then drive it to dinner, and then to my parents place in Orlando to go visit them. A true testament to the quality of the build as this all happened a week after I took delivery of the car! Man this thing is so fun!

Summary: I sent Nth Moto my 2015 Viper for a TT setup and the build has exceeded all expectations in terms of quality, performance and drivability. To be able run 191.8mph in the 1/2mi on the 5th pass after driving 500miles is astounding. It makes for such a fun street car that can also do serious work in racing situations as it’s literally a push the start button and go drive type of integration. Nth Moto has really knocked it out of the park with their bolt-on TT kit! But more importantly they created an awesome customer experience for me. The questions they answered pre-sale, to world class support I received after I took delivery of the car, at the Ocala event, and afterwords is second to none. I’m looking forward to continuing to enjoy this car and seeing how it evolves in the future…. with their continued help!

Thanks for reading!

That 1/2 mile video just made my winter that much longer cool car and it's really nice to see a fantastic customer experience! Congrats to Nth Moro for creating this kind of feedback as it is truly priceless as far as marketing is concerned.

[outnumbered]

Loved reading that build story.

[pdv25]

Such an awesome build with great results! As always another great build from Nth!

[7TH_SIGN]

Excellent work Nth! On stock motor! Love the innovations you guys create. I've never seen a boost control like that. Almost looks out of this world yet so easy and simple. 191mph rwd on 19s! Congrats!

[plumcrazy]

very sexy

[Jack B]

It is hard to comment on the obvious, however i do not think I have seen a more complete package in my 16 years with the viper community. Good luck, have fun and enjoy the "obvious".

This is a yummy setup. Great pass and driving!

I'd love to see this OBJECTIVELY compared to a Calvo setup, as I may go this route at some point.

[IndyRon]

That's the way to build a viper. Right up there with UGR or any top tier builder. I'm hoping for something similar once I get my hands on a Gen 5. It's so nice to see custom fabricated pieces and OEM or better quality in their manufacturing.

[DADS ACR]

CONGRATS! Great build story. Enjoy and be safe.

[1.8t]

Badass!

[Ripper]

Very Very cool!!!

[99RT10]

Nth Moto is top tier, great build, great car. Congrats to both parties!!!

[Bleed viper]

Beautiful build and awesome results. They do some great work. Did you say you are from GA? What part, if so?

I can help you out with that. I work for wannagofast on the side and have seen just about all the different build combinations there is. I can honestly say they are both good builds and are doing things the right way. These are not cheap by any means, but that's also what makes them great. When a shop doesn't cut corners to save a few bucks here and there, it allows them to do things right. As a gen V owner, who would I go to for a big build? It would be a flip of a coin. In addition to the build, the staff with both companies has always been nice at events and are true gear heads.

That might sound like a politically correct reply to your question, but it's the truth.

I had a feeling that would be the case. We are blessed to have such great tuners paying attention to this platform.

[Junkie]

Great right up man, its nice to see someone actually out and about beating on these cars! This thing makes me really excited for mine!

Fantastic driving, fantastic build quality. All around winning combo!

[Space Truckin]

Woohoo... BadAss on oem w 11.5 boost...wow....

[ViperDC]

Nth moto does incredible work. Sick car!

[Geronimo]

What was the build time on this? Cool as hell.

[mnc2886]

This is freaking baller!

I agree, I love the simplicity of the boost control. There are other ways to accomplish this like via CAN integration into the steering wheel, but I prefer this approach because it provides a quicker and more straight forward method to get to the setting I want when compared to scrolling through an arbitrary menu on the dash display. The colors are a great way to easily determine which setting is for which fuel.

[Space Truckin]

^^^U have a PM^^^

[TooBlue]

Congrats. The car looks and sounds great!!! 191 mph is flyin'

Just curious, were you using any of the Motec traction controls? Car looked a little loose in first and second. I do realize you were running on 19" rears.

I'd love to see this OBJECTIVELY compared to a Calvo setup, as I may go this route at some point.

I think it would be hard to get a truly objective opinion unless you find someone that owns builds from multiple shops. Additionally, there are so many parts of choosing a builder that are subjective such as the aesthetics or design philosophies. I personally feel that the Nth Moto product is the most aesthetically pleasing and most detail oriented system on the market.

With that said, I'll offer my $.02 on how I thought about making this decision. This is not limited to Nth Moto & Calvo, but also applies to the numerous other shops that offer services for the GEN5 Viper platform. We should feel lucky we have so many options!

First and foremost do not let the distance to the shop be a factor. The cost of shipping a car is minuscule compared to the dissatisfaction of a sub-par build.

Next, and I know this will be controversial, remove any influence by how their "shop cars" perform. Shop cars by definition are generally built and tuned beyond what a typical customer would do simply because they have to be a rolling advertisement. Thus, you will often find that the shop cars run more boost, are tuned more aggressively, and generally take on more risk than the average customer would accept.

The next course of action is to talk to customers of the shops you are considering. Send them a direct message, or give them a call. Most customers love to talk about their cars and experience as it is this hobby is their passion. I would even suggest that if the customer is willing, schedule a trip to check out their car in person. We are all spending a considerable amount of money on these cars, and a flight ticket to check out the quality of the work, drivability, and in-seat experience pales in comparison to making the wrong decision. In my case, there was another local Nth Moto car that I spent a LOT of time around, so I didn't need to do this. However, if not for that, I probably would have bought a flight ticket to GA.

From there, call the shops in question and discuss your goals & requirements. Pay attention to how they advise and guide you to reach your goals. Goals are not strictly performance oriented but involve NVH, drivability, responsiveness, and the overall power band (NOT peak power). Case in point: my car dyno's in the low 1100s and runs faster than many cars out there in the 1/2 mi that dyno 1200hp+.

Consider who has the most experience with the Viper platform? There is no compression algorithm for experience, and some things you just have to learn by doing. You, as a customer, want to benefit from this experience and all the Vipers the shops have built and made successful and lessons learned.

Finally, from an objective perspective, pay especially close attention to how the stock motor cars are performing. Stock motor cars do not have the luxury of turning up the boost to the moon to make up for any turbo system inefficiencies. They have limitations which require them to perform within a certain window, and this tells a great story around which turbo systems work better than others.

After considering all these factors, the decision for me was a simple one: Nth Moto.

Good luck in your journey!
