Faster track car

[Arizona Vipers]

Let's start a thread about how to make the Gen 5 a faster track car.
I'm ordering the TA sway bars and springs and getting TA alignment (probably with a little extra front camber).
I've already installed the TA 1.0 splitter and spoiler. I run Hoosier's on Sidewinder II's..
Any other ideas (aside from obvious horsepower upgrades)

My car stock was light was lighter than most Gen 5's, just under 3200 lbs when I got it, empty fuel tank, and Track Pack.

I dropped another 28 lbs with Lithium battery install and another 52 lbs taking the passenger seat out.

Next is windshield wipers/wiper fluid tank... That should be a few pounds, and a reduce my drag coefficiant a small amount....

Any other parts/ideas out there to trim lap times down? (before getting hardcore with things like A/C removal, stereo removal ETC.

[Voice of Reason]

I want to add the ACR diffuser to my TA but I'm waiting on something aftermarket that's a lot more economical than the insane OEM pieces.

TA aero with ACR difuser out back will look awesome.
Those TA2 / ACR front canards look reduculous though.
Any version of the front splitter.
Active suspension.
Upgraded brakes.

Boom! Faster than 95% of the cars out there. No hideous aircraft carrier bolted to your decklid either.

I got the exhaust, I don't like the way they do the bend, looks to me like it will cost me horsepower. I've been trying to talk Lou Belanger into making me some titanium exhaust with smoother bends..

Has anyone confirmed faster lap times with this suspension package? I would be interested if so..

[Arizona Vipers]

Buy an ACR!

hehe, I might. But right now I like being the underdog out there with no aero etc. I bought my '13 for $64K and have less than $70K into it now. An ACR will be more than double the cost.

Did you happen to dyno before and after the titanium exhaust?

I've got the factory track pack brakes and have been very happy with them so far. I'm running SRF and bleed every 4 sessions and there's no fade. So bigger brakes for me at this point is just adding more weight.

Absolutely, CJ Wilson set the track record at his home track with them on his ACR, Michael Levitas has been absolutely flying in his TA around VIR, and I know we have another member here in CA that set new personal bests with the dampers on his car as well. I also went faster than I ever had previously at COTA with them on my car as well.

I've driven on a few suspensions. That VE suspension is one of the best I've felt.
Put down some solid lap times at Buttonwillow and WSIR

I love the MCS....2:23 at COTA.

[ViperDaleE]

Adjustable shocks and set up and then learning the proper adjustments for your shocks is the fastest way around any track. Taking 2 pounds or 5 pounds off your car will make no difference in lap times. Very few people reading this thread have the driving skill to show a lap time advantage with a 50 pound weight difference on a 3200 pound car unless Ben Keating or Kuno Witmer are reading this thread.

There's truth in that statement!

I might buy some 19" fronts and give this a try...

I disagree. Not even counting increased cornering ability with less weight, a 50 lb weight reduction would shave around .05 seconds off your average straight. It doesn't matter who the driver is, skill for skill a 50 lb lighter car will accelerate faster than an identical 50lb heavier car. .05 seconds on a track is a HUGE. Same with cornering. Identical cars, the one weighing 50 lbs less will have more cornering ability, no matter how slight this may be. For me, .05 seconds on a straight is huge.

[Memphis]

It's not cheap at $8k but ESE has CF wheels that would knock a good bit of rotating mass off. In the Corvette configuration they have an 18x13 wheel weighing in at just under 13.5lbs and 14lbs for a 19x13. A set of those and race scrubs would be a mean combination.

[BLUETA#1]

[QUOTE=Arizona Vipers;208222]Do you have a best lap time with the stock set up?

I never had the car the stock.....I picked it up from Woodhouse with the suspension installed. I did however play with alignment a lot. I have never even tracked the car with the OEM tires. I remember that my best lap in my first ever session in the car last April was a 2:37.

[Jprince]

Another change that made a huge difference on my car is the nth moto Carbon clutch. It is 15lbs lighter than stock and it really makes this engine rev way better. The shifting is 1000 times better than a stock clutch as well.

[serpent]

I thought the fronts are 18? I know the gen V runs a staggered setup, why not get 18" rear wheels? Smaller diameter wheel will drop weight. Carbon DS? Do the vipers come with an aluminum fly wheel?

This is one of the reasons that my car has been so successful running the 1/4 mile as well, and the weight savings was a nice side benefit to the Tractive/DSC dampers along with getting to keep your bi mode suspension in tact. The car rides much better on the street and books it on track.

Num, num num !!!! Waiting to see what's up with the 2017, but I'll def want these goodies !

[TheKosherStogie]

I'm selling my Viper and will sadly be selling my VE suspension. Man how I wish suspension were universal and I could just install it on the next car!!��

If they made Viper wheels in Viper sizes that weighed the weights you quoted I would buy them..
I made another post about carbon fiber wheels and everyone posted about how they aren't really any lighter than the Sidewinder II's.
The Shelby GT350R carbon fiber wheels are quoted as much heavier than what you quoted and they are much smaller wheels.

Are you getting an ACR? Or graduating to a track only race car? I wish I can afford a dauntless racing car (stohr). Shatter all the times at any track!! Yeah, different car.

Wow...I think the Viper is by far the best shifting car I ever drove. I love how smooth and precise it is. What changes / specifics did you notice with the new clutch?

[Jprince]

With the stock clutch the engagement was toward the bottom on the pedal and when running the car hard and speed shifting I had problem with it not releasing and sometimes a grind in second or 3rd. The stock clutch also did not like a lot of slip when making a hard launch and it aggravated the problem. All of that is gone with the nth moto Carbon clutch. The engagement is about 1/2 way in the pedal travel and this clutch handles the slip no problem. The clutch disk are feather light therefore the synchronizers are not working at all. Even though the clutch is 15 lbs lighter the flywheel is heavier than stock, so the weight is where it needs to be.

I am a fan of the VE dynamic shocks. I have not run willowsprings with them yet but I was as fast in my GTS as guys with my skill level in an ACR in my run group at Chuckwalla. Willow would be a different story in that comparison as it is a much faster track in terms of overall speed. ACR could damn near drive upside down through 8 I suspect. ok....maybe not...but aero is gonna help in 8 for sure.

Tires and brakes would be next.

It's not just about adding go fast parts. It's as much adding stuff that makes you fell more comfortable in the car, keeps the car planted at speed, knowing your brakes are not going to fad, etc. Smooth is fast. Getting rid of bump steer or having weight balance set as close makes it easier to be smooth.

A few years back I spent at least two weeks setting up my Gen 2 ACR for an event at willow. I was meticulous with the alignment, balance, bumpsteer....everything I could adjust. I picked up 4 seconds over my best times before because of spending the time on the details. It drove where I placed it, stayed there and drove like a dream. Well....until Sunday......but that's another thread.

[Nine Ball]

It is important to note that you don't have to be a pro to notice lap time improvements, but you DO have to be a consistent driver. If your lap times (sans traffic) are within a couple tenths of a second on each lap, then you will certainly notice improvements made to the vehicle. If your lap times are all over the place, then the best advice would be to take some driving courses and get more seat time. Throwing modifications at a car should never be the first choice, if the driver isn't conditioned first. We all drive at our different skill levels, but gaining consistency is key.

[Snakebit10]

Sounds like he is getting something non-viper as I would think that the Tractive would just port over to the ACR if he was getting one. Anyway can't go wrong with MCS or Tractive from all the data I have read and heard on both. Would be nice to see what Randy would do on Laguna with a Tractive equipped ACR.

Their website says no fitment for the Viper. Am I missing something? Is it in development? $9000? Plus I would assume it would need a lot of bracing?

What color was your GTS? I thought I was the fastest non-ACR Viper out there in Chuckwalla.

Yeah, there is always room for driver improvement for every driver in the world. I was just looking for modifications to a Gen 5 Viper that make it a faster track car. Obviously seat team helps make the driver better. Your shifting tutorial has helped me out a LOT!

[Nemesis]

I am going to say this and I think you understand it, by the time you spend what you think you need to spend to get where you wan to go, you will have paid for an ACR........It is cheaper to buy it then try and build it.....

Yeah that's the case for most in the long run, but I got the car for $64K. It had a rear bumper repaint so I stole it.
The TA spoiler front and rear was about $3K through Xtreme Supercars. I just ordered the TA shocks/springs and sway bars for about $3000.
So I'm in for a little over $70K at this point, about $70K-$80K less than a new ACR. That being said, i'll probably order an ACR soon. LOL!

I'll try to get by without the aero and adjustable suspension for as long as I can!

I remember your car now, I saw it on the paddock but didn't get a chance to see you on the track. Nice looking car dude!

Yess ! Randy in a Tractive, Heads & Cam ACR !!!

Randy spent almost a full day in one of our stage 1 ViperExchange TA 1.0's, with our tractives on Hoosiers. He said it was damn near as fast as the Porsche Cup cars he races. But what I liked from his day the best was that he said that it was the first time he had truly driven the Viper with a proper damper under it. He drove the ACR E a month or so after that and loved that as well.

[catwood]

I didn't run red as I had never been to Chuckwalla. I told myself to go easy and I did for the most part. Right up until I caught up to someone.
