Procharger Crank Support:?

[80FoxCoupe]

What’s the crank pulley diameter on the gen2 procharger?

Stage 2 crank pulley for 15-17 cars is 8in., For 18up is 7.65in.

Stage 2 crank pulley for 15-17 cars is 8in., For 18up is 7.65in.

So how are people only seeing 13psi with a 4.25 or 4.13 pulley? I saw 14psi with a 4.38 and I have a 7.65 crank pulley. When talking to Jon Lund Jr while trouble shooting my fuel delivery issues he was pretty sure I was seeing 15-16psi based on the logs and a 4.38 pulley at 7500. I figured I was around 11-12psi but after really paying attention to the boost gauge it was every bit of 14psi.

Restriction = boost. Gen 2 heads flow more if you have stock gen 1 top end typical you would see more indicated boost. Plus it’s also dependent on weather, also cam swings

I need more info. What engine, mods, head unit?

I get all that, Gen 2 heads flow 5% more TMK and we’re talking April in S.FL

gen1, D1, ported Boss , kooks shorties, ORX.

Are people logging boost or guessing? I know I didn’t spend much time staring at the boost gauge at 7500rpm and it was surprising when I forced myself to watch it.

I dont put too much thought into boost pressure. If there is no belt slip, im just concerned about output. Dont get caught up with comparing boost with other combos. Barometric pressure, water grains and other variables will swing that number.

Anyone else notice the crank support is now advertised on the procharger website.

About to pull the trigger on the new crank support. Anyone jumping on this? I really want peace of mind and I'm about to max out my P1X on my 18.

Hi. I was questioning the crank longevity, reliability on cars using high loads on the end of the crank pulley. To me this is a must for any high output applications.
My Concern is, Is this new Crank End Support Bearing Assembly engineered to be perfectly centered with the crank to take into considerations the Crank hydrodynamic Lubrication (Crank and Main Babbitt Bearing oil separation clearance during operation). The 5.0 engine crank will float ever so slightly between the main babbitt bearings. The Crank support bearing I guess is a roller bearing which has a finite fit with little to no variation in movement except for the roller bearing normal play. Will this interfere with the crank main Babbitt hydrodynamic Lubrication Seperation.

Your crank snout will be fine, but you'll spin all your mains. It's a trade off.

I just wish I could keep my front sway bar. I'd have already bought it if I could.

Yep, sway bar gotta go.

Will this be beneficial if I have a H/O kit (non stage 2) with a stock crank pulley?

Not really. You have the least chance of anything going wrong. If you start running a trans brake or a 2step then yes but other wise you are pretty safe

 

[SolarFlare]

stage 2 is very safe. Install it right and you'll be fine. Stage 2>>>>>>HO
