Gen 4/5 head

[Revolution]

Just gauging how much interests there would be in a high flowing CNC'd head option with little down time? All heads well be tested and flowed before release with or without standard size valves. This is not a for sale thread this is just gauging interest thread.

[IndyRon]

I'm interested, especially if performance would be on par or better than the reputable porters like Arrow or Greg Good.

Good to know Ron! I'm expecting azing results as I have never been disappointed with his development work yet he's top notch! Also hoping that a quick turn around time would make this a lot less painless.

[ACRucrazy]

I would be interested.

[FLATOUT]

I'm interested. Greg is not far from me here in Houston so I might go that route, but I am definitely interested in other options.

[J TNT]

I would be interested in the horsepower gains through out the power band and the cost to make it happen

With head porting, there is a component of "black magic" involved in that, often, the heads with the highest flow numbers don't always translate to the most hp area under the curve. Obviously midlift numbers and velocity are important as well as platform/engine specific tricks that may only apply to these V10's and that is why reputation is huge when it comes to headwork. If this is someone new to the Viper platform, they'd have to be proven performers and if that can be done, I think you'd have a hot product.

The heads will be proven before they are released and are being worked on as we speak, just like my view on dyno's, flow bench is only a tool. Were also using airflow analysis to monitor velocity and other crucial factors. My partner has been in the business for years and holds many records but all heads well be tested both on a dyno and track.

Who is your partner?

[Revolution]

My partner is Bret and I just received my first set of new cores so the fun is about to begin and more details will be added, also just put a big order in for header and exhaust parts should be a fun spring

[XSnake]

There is def. a market for these. Last I knew ordering a set from GG takes about 6 months to get as he is very busy and has that many orders. I know he was working on C&C program to speed up the process but never heard the results. I found a used set as I wasn't willing to wait that long.

And who is Bret?

[Revolution]

Got a new set of Gen 4 heads to start working on

Shhhhhh! It's a secret.

Shhhhhh! It's a secret.

Not a secret I will see if he will join the forum!

Here is some other work were doing for my other car in hopes of producing 600Whp per liter

Specific tapered runners


velocity stacks on each runner entrance



Injector boss's, and flange to mate to plenum


Picture of the Cnc runners as they enter the CNC intake ports!

That work looks amazing.

[Revolution]

Glad you like it Ron! Those are just a couple of teasers on the mock up head my head is running Ti valves and beryllium seat and his bowl work is amazing!

[FLATOUT]

Well Damn! Artwork man you can't put those on a car.

[Revolution]

Thanks but that's why I build this stuff is to put it on and use it. Just like a car if its not used its wasted in my humble opinion.

[IndyRon]

Can you imagine if we just made 1/2 that...say 300rwhp/L. Crazy!

That's what my next viper will be a twin turbo car and keep this one NA!

Now that is craftsmanship! Beautiful work.

Thanks Mark I appreciate the comments guys and hopefully have some Viper stuff to show you in the next month

Will this be just gen 3/4 specific? Any Gen 1/2 love?
