Video of my heads cam viper with exhaust reconnected

Car got dropped off yesterday. I love the sound of it!

[BrianACR]

That sounds nasty!!! Love It!! Creampuff no longer lol.
I see in your signature you're the pilot car for Havik Performance Gen II HC. What all did they do to your heads? Custom cam? Cam specs? Dyno results??
Which exhaust you running on it?

[CSXT802]

It's hand ported heads with 2.02/1.60 valves, springs, retainers, seals. Custom cam (not disclosing the spec). Hopefully will be dyno tuned at the end of March along with a gen3 car under going the same treatment. Exhaust consists of M&M headers, cats deleted, and mopar performance borla 2 muffler system.

Nice. I'm impatiently waiting for my heads to come back. Basically the same treatment. Ported and polished, same sized valves you got and custom cam. Putting in 1.7 rockers too. Also getting the intake manifold port matched. I've got M&M headers+cat delete. Only difference there is I don't have the Borla system. A friend custom built mine for me
It'll be interesting to see what kind of numbers you put down!! Make sure you update this when you get her dyno tuned!

I've got to stop watching all these videos, the need for a head/cam upgrade is getting really bad.

[BrianACR]

That sounds so awesome! Can’t wait to get mine put back together!

[CSXT802]

Dyno results!

[Camfab]

Great results! Hows off idle drivability, that's usually the toughest part of getting these cars right.

Dyno results!

Scaling looks a bit off. HR and Tq should intersect at 5252 and not 4500. Other than that, numbers look good.

[BrianACR]

Those are pretty impressive numbers!
Ya I second what ellowviper says. Hp and TQ should always intersect at 5252RPM.

[Camfab]

Good catch on the graph, I didn’t even notice that! Oddly enough the graph seems to have differing scales on opposite ends, making the hp appear to be greater than the torque. This motor makes more torque than hp. I’m guessing the shop is trying to make it more marketable and “normal.” Torque wins races, hp sells parts and labor.

Looks like great results and the car sounds fantastic! Do you have the SAE dyno graph?

[CSXT802]

It's my understanding that it's not crossing at 5252 due to the torque and power scaling being different from left to right.

For reference here is the dyno sheet form the gen3 car with the same head cam package same dyno same day.

You can see in the video the dyno screen at the time had the scale the same left to right showing the cross at 5252. I must have inadvertently changed the scale on one of them while plotting the 3 best pulls. We made 14-15 pulls during the tuning session. So it was alot to go through. Trust me there is nothing funny going on here. The subsequent highway pulls with the gen3 car prove the power.

Here is the gen3 car on the Dyno.

Car sounds great ! Enjoy !
