Viper Exchange/Arrow Racing Stage II Heads and Cam Engine Dyno Vid!

[FLATOUT]

Here's an Engine dyno pass with a familiar face keeping close watch :) Our combo is making 90-100hp more than stock and putting 648-650 to the wheels SAE on the Viper Exchange Owned test mule on Arrows chassis dyno. Second video is a test car running hard at Gingerman just so everyone can see that our heads and cam package is working and that we are in the final stages of bringing this to production.

We have an active list of sold kits so if you have any questions or want to reserve your spot send me an email.

Thanks for the vids! Does the test mule car have AR Headers on it and if so is anything new done to prevent burning the O2 wires?

Yes the cars are running and were calibrated with ARH headers. We wrap and insulate the O2 wires and extensions in DEI heat wrap products, and have not had any issues. All three major header brands for the gen V will melt O2 wires on aggressively used cars so it's a precaution we should all take.

Sounds nice and healthy!

That thing sounds wicked on the track!

Chassis Dyno Numbers!

[1.8t]

Strong curve and numbers. Looks like a great N/A setup. Sucks for those of us who have to deal with emissions :(

I noticed on the vid that those are Mustang dyno numbers as well :)

[Dman]

Wow, that's north of 750hp at the crank ... not sure what else anyone could need while staying away from the challenges of FI, like heat, etc. Crazy impressive for essentially heads / exhaust and a tune.

[Voice of Reason]

I compared their graph to mine since my numbers are also from a Mustang dyno. Peak torque is only up 13, however peak Hp is up 65! So this thing breathes a LOT better in the upper RPMs. Very nice!

[Victxv10]

Awesome!!

[KB Viper]

i can't wait to get mine installed.

[Aspirations57]

I would guess this setup would kill the powertrain warranty? What would the numbers be on 91 octane Utah fuel:( ?

[Jack B]

Forget the peak numbers, look at the diff under the curve.

They used an aggressive filter/smoothing, this filter could have lowered the peak numbers by .5 or 10 hp.

I'm really liking this package. Looks like a lot of R&D has gone into this.

Be there or be left behind.

I agree Jack, I feel like for the guys that like big dyno numbers that there will still be larger SAE corrected numbers via dyno jet. I also just heard from a supplier that we are going to have some new header options that would bump this package number even higher. I don't see why we won't see something that's 660+ SAE

If you guys want to get on the list give shoot me an email awheeler@viperexchange.com

You can't beat a Viper package designed by Arrow and ViperExchange with guys like Winkles involved. It's been almost an OEM level effort and the time and attention to detail is what you would expect out of a company like Arrow.

Going to be great on the road course and drag strip.

[Murpowa]

650 whp is solid! Great stuff!

Agree and expect it to make a few more SAE on a dyno jet. Going to be the perfect compliment to an already wonderful platform!

If only the package included rear O2 simulators and left the rear O2 monitors on so that there were enough monitors in the ready state to pass an emissions inspection. But I'm sure that's an EPA thing that Arrow does not want to get involved with hence "off road" use only.

Also I think more people would be concerned with the dyno difference from before and after to see actual gains not just a high dyno number on a dyno jet. Or a comparison from a car with the Arrow PCM headers and underdrive pulley, and then one with the cam and heads. I for one would love to see that comparison in the same dyno SAE.

Great job none the less and I'm envious I'm in a state where I can not have this package.

On another note, when the supercharger becomes available, I'm wondering if you could swap with the stock PCM and drive it, obviously staying out of boost. I don't see why not.

When you look at the curve, it's basically 630WHP in the higher RPMs as the 648 was only a spike on the graph from ~6100-6200 RPMs. Voice of Reason put down 597 WHP with just the Arrow tune, also on a Mustang chassis dyno. So maybe 30-40 WHP more up top from the heads/cam/headers/exhaust and minimal gains in the mid range? Don't get me wrong, it's great that there are now these options available to us but $13,900 for only 30-40whp more than the Arrow tune? Just doesn't seem like a very good value whereas just the tune offers pretty decent bang for the buck.

[Jack B]

That curve is typical for our cars. Just a guess, he let off the throttle near the peak.

Secondly, you do not look at peak numbers, it is all about area under the curve. The real proof
will be at the strip

You can't just pick the highest dyno number you've seen and use it as the point of comparison - his car put down way more than it should have with the tune only (+62 at the wheels), and I'd consider it an anomaly rather than the norm. Even if we call it 630 RWHP, that's on a Mustang Dyno, and those always show lower numbers than a DynoJet.

Is it the end-all, be-all of performance? No, but it isn't meant to be...it is meant to be a plug and play solution for reliable power that can stand up to abuse on the street and at the track. I'm sure there are others that will shove donkey dick cams in their Gen 5s when they get the kinks worked out, but they'll suffer from the driveability problems that plague such setups (soggy low end, erratic idle, etc.).

I think they did a good job of catering to the masses...there will always be people that want a little more, but those same people will need to be willing to put up with some additional headaches along the way. Arrow has already ironed everything out and packaged it up nicely for everyone to just slap it on and go out and enjoy more power.

[FLATOUT]

The package will offer a substantial improvement over a Bolton car. As already mentioned comparing different cars and dyno's is a recipe for inaccurate information. We'll have before and after same car same dyno info available.

Glad to see Winkler enjoying his retirement!

We are very fortunate to have Dick Winkles involved on the stage II and the supercharged package. This is as OEM as it gets without being able to directly order your car this way from the manufacturer. Viperexchange offers the 700+ hp new Viper solution. Call Bernie and Courtney, pick out a new Viper and add the stage II kit.

[Jack B]

It is a positive perfect storm for the Viper community.

[G.OLI]

Awesome work! Congrats Viper Exchange!!!

[Orange TA]

Is OEM -- in terms of Gen V Vipers -- a good thing though? I mean just look at page 1 of the Gen V threads and you'll see three rod knock/engine replacement threads there alone, not to mention the ~15-20 other documented cases.

This is going to hurt some feelings on the street and at the track.

I can't imagine what a 750hp ACR Extreme will do out on the road course, good lord.

I also am very excited to see someone go 140+mph in these cars NA at the strip (it should be so with this kit). Exciting times to be a Viper owner!

Dick has been with Viper power train since it's inception, I couldn't think of a better team to be aligned with.

Appreciate that!

Your point is?

Any more info on this set up? When my ACR extreme comes in to Woodhouse, it will have this head/cam/header/exhaust/tune package.

What would you like to know? Glad you chose to go with our package you're going to love it! The installs at ViperExchange are dynoing from 640rwhp to 660rwhp depending on exhaust combos and small supporting mods. I own and drive our first original test car outside of our mule in Detroit and I now have over 7,000 miles on the package. ViperExchange has driven both of our test cars from Houston to Pikes Peak and back (3,000 miles) without issue with Dick Winkles.
