VRP Supercharger
I see that VRP supercharger kits will make around 775-800 WHP. My son has a 2012 P31 with the forged internals so the question is do these engines take that kind of power and stay together?

Ive seen 2 installs on stock engine and they put down 630-650 whp the high 700-800 claims seem to be a unicorn with tons of other mods and or fudged dyno numbers... but to answer your question yeah upper 700 whp to even 800 seems to be fine. Getting into the limits of fueling at that level. The transmissions seem to only hold into the 6xx whp levels though so you may end up needing a transmission upgrade if you are into the 700-800 whp range

Agree with deadly, I've read 650whp is the transmissions limit stock, so that will be the actual limiting factor as the internals have been showm to be ok to near 1k crank hp.
VRP has some good builds behind them and also a ton of unhappy people. Some tuners refuse to work with you if you have their kits or parts though.

None of those cars have any box times, 1/4 mile times or anything to verify they are making the power. Also shady when vrp claims those numbers with only the supercharger kit not the cams e85 etc. not even saying that's not what they make but it is sketchy at the very least

Transmission is easy as I have been an auto trans builder for over 30 years. The trick, in my opinion ,is to have the parts Cryogenic treated and that has proven to make a HUGE difference in all my performance builds and tow vehicles.

So as far as numbers go around 650-700hp is where you for fueling limits and shortly after that the trans limits. VRP kit the use the Whipple 3.0 great head unit but for some reason a few tuners who will not touch it. also, it's still running a 6-rib setup and have not said if an 8 rib is in the works. last part of the VRP kit that was already brought up is not a single one of these VRP kit users Big HP guys have hit the 1/4 mile for times. Weistec maybe using an outdated Whipple 2.9 head unit but still holds all records for power and times also haven't heard of anyone refusing to tune them.
My pick on blowers that are available in this order would be.
Weistec
PTG
VRP
if I could find a Used Magnuson kit I would go with that first.

63 Motorsports cam adjusters, BS tappets, VRP street cams, PTG crank dampener, 800cc injectors, a Wavetrac and a smattering of ARP head bolts and stuff. Have decided to go with Barry at eightysix for the tune.
Hoping to be wrapped up before Spring hits in Ohio with all the details. Sticking with the stock Magnuson 5.5psi for now and seeing how close to the transmission's limit I get before even contemplating more boost. As is, the 2 out of 10 times the fueling, SC and trans are all in the same page it's brutal. I can't imagine post-build.

For those wondering, I’ve run both the Whipple 2.9 in standard and in ported blower forms, plus the Whipple 3.0 standard as well (all on my Camaro). The 3.0 made over 100 WHP (1059 WHP vs 955) on the SAME pulley combo. And even at 1059 WHP it’s far from tapped out. The 3.0 is a very potent rotor pack. For cars making 600/700/800 WHP, it’s cake for that rotor pack.

Excellent information. I am starting to wonder if the VRP/Modern Masters dyno numbers that they show live are really that high. I would think to myself ...775-800whp with just a blower install was crazy.

It's not. That car has cams,e85 etc. that's my point they claim 800whp with their kit. But in reality it puts down mid 600s out of the box. They do so much shady stuff it's hard to warrant using any of their procuts which is unfortunate as the number of aftermarket companies making things for our cars is so low to begin with

Modern Masters is running a 62mm pulley, E85, Fueling, Cams, Full Exhaust, Tuning and you're easily in the 800whp+ range.

Horsepower is dependent on what pulley setup you're running, the kit comes with a standard 76mm pulley and 630cc Injectors for 93. The standard setup makes roughly 650rwhp.

The process essentially work hardens them, without making them equally brittle.
I’m not even sure I have heard of cryogenic treatment.
What does it do, to the metal, and how does it work?

The parts treated are taken to 300 degrees below zero and it changes the molecular structure of the steel. I works great for brake rotors to prevent them from warping.
Go on "300 Below" web site and it will explain it in better detail. It's cheap to do as well.

I had this done on my Volvo XC60 which I have taken several times to tail of the dragon. Previously I could count on one set of pads and rotors to last me about every year or so with a trip to the dragon. They weren't fancy pads, just EBC Red pads with Volvo branded rotors.
After cryogenic treatment of the rotors, it was a dramatic difference in the wear and longevity of the rotors to where I wasn't worried about gouges and excessive wear that required the rotor to be replaced every year. Those rotors stayed in service for two additional trips to the dragon, and another three years after that with simple street driving before I replaced them with standard rotors since I don't drive that car as much as I used to anymore.
