D3 Performance Engineering Gen5 Procharger Development

[moe.basilo]

We finally got the rest of the 3D components in, huge thanks to Engatech for helping with the prints since they were so large. We got them onto the car to test fitment and installation, we have noted a couple small changes we need to make in the CAD drawing and we should be ready to have a prototype CNC machined for testing!

Awesome job evan .. Thumbs up for all the hard work and the time spent on the car.
I have a question evan, How much psi it will handle the 8 rip belt with no slippage from your experience? Just curious because I'm planning to upgrade the engine internal in the future.

It isn't just a matter of the rib count. Has more to do with the surface area that this belt covers around the blower pulley, and the crank pulley. From the photos, both pulleys are large diameter (good) and the idler/tensioner design has maximum circumference belt-wrap in mind. PSI is also a measure of restriction, not a good relative indicator vs belt friction. Most Gen 3 Paxton cars can achieve 12-14 psi with a simple green Gates belt, and that is on a much smaller blower pulley size. The Viper engine makes 900+ rwhp at those boost levels.

Perhaps it is the angle of the pics, however is there any interference with the airbox / intake on the current set up?
thks

We will be making an airbox for the system but yes it won't use the stock piece.

[Evan@D3PE]

Is it weird that this pic turned me on a little?

It would be weird if it didn't

Why?
Is there a benefit to an air box in an FI application?
Or is it just to facilitate air filtration?

More so to get "clean" air from outside of the engine bay

Ah-ha!!

Good idea, if you have sufficient room for the volume demands!

It'd turn me on more if it was for a Gen IV...?? (sorry Gen V'ers, that's what i've got)

thanks nine ball for the info

As funky as the Paxton airbox looks, it still flows a lot of air and uses the hood scoop to feed it. I've dyno'd and ran the drag strip with the bellmouth in place, as well as the airbox. No performance difference. The bellmouth just looks cooler, but filtered air is better. haha

On my Paxton Gen 3 car, I ran the dyno without the air box and then with the air box back to back...it made an extra 130whp with the airbox installed.

130?? That's an insane difference.

Sorry...I meant 140whp http://driveviper.com/forums/threads...-running-right

Now that the brackets and pulley are out at the CNC, we started with the intake design. We installed the OEM airbox then scanned it to know our height limitations along with the point which meets the hood. Then we removed it and scanned the inlet of the supercharger for routing and the radiator fans for depth limitations.

Pretty awesome that you guys are documenting this!

[slovenom]

You guys Rock!!

[Jdmuscle]

Very excited to see the outcome... Good job D3

I believe that. Airflow into the blower would be horrible. But, all that is fixed with a bellmouth.

[DZnutz]

Running around without a filter is a very bad idea

Hey Nine where did you get that thing on the blower
Is that what you are calling bellmouth?
I want to get one for my paxton
thanks

its called a velocity stack

Goodies on the way from Nitrous Outlet just for kicks

In addition to the blowe?

Of course!

Hey Evan, the intake pipe it will be twin pipe from the intercooler to TB or single pipe from intercooler then Y pipe to TB.

Thanks,
Khaleefa.
