This car went 7's with a P-1X and a 10 rib belt.....

[80FoxCoupe]

It's curious why one would need a 10 rib on a P1X. At what pulley size do you start getting slip at typical coyote redlines?

It's possible that 10rib may not be needed. But as we know in a race application you do more than the minimum. You exceed the minimum to increase reliability, service life etc. That's how you get to the front.

Maybe, or maybe again, it's misleading and to get into the 7's you have to spin the blower with a tiny pulley way beyond what you or I or "normal" consumers are allowed to do without voiding the warranty.

This is where the questions about PC's own CFM data come into play and how an alleged 3800 lb vehicle can trap 175 mph with a blower that's "rated" for 1275 cfm.

If you're spinning the thing to oblivion to make the power to do that, fine. Just admit or be open about that. Then the whole "we went 7's with a 1275 cfm blower on a full weight car" becomes less impressive. When you're either a sponsored race unit or one of the cool guy click you can do things like spin it to the moon because either the manufacturer will help you out or you can afford to replace things at a race team interval. For mere mortals who are restricted to the published limits, it's dubious that you could propel a 3800 lb vehicle to 175 mph on the stated blower limits.

they rate the blower cfm and rpm at their limit

they aren't saying anything about "you can do this too"

Prochargers own hp figures are exceeded by customers that haven't even maxed the pulley out, they publish that on their site as well

"Exceeding the published supercharger RPM, failure to follow service procedures, or using improper supercharger orientation will void the warranty."

the site says "P-1X™ is 875+ HP capable"

and on another page:

"THE P-1X AND D-1X BECOME 1,000+ HP PERFORMERS:
We rate the horsepower of these units at the crankshaft, however, our customers have already started to show off numbers far exceeding our expectations. They are doing this by having well-dialed camshaft/engine combos and some wizards behind the engine tuning. We just love seeing our customers meet their goals and exceed them! "

I suppose that I look at it in a simpler way. She took a p1x with a pulley ratio set by NMRA, put it on an optimized race car and tested/raced it until it was a record holder. That's it. Getting caught up in what a chart says, what you think it should do, what it could do on a mere mortals car is irrelevant. There is no stage that is more scrutinized than a record holder at a legit sanctioned race. To question if this car fit the rules is a slap in the face to NMRA tech efforts. Make no mistake while that setup could be street legal, that is a prepared, purpose built car. Moore's efforts are witnessed and documented, it's not some FB rando making claims to hype up a brand. Look at Prochargers winners page. Those people make a living racing, they are known in the drag racing world, respected and winning on the biggest stages. Go to a race, talk to them, see what they got. Nobody here will convince you.

I got it.

Here's the summary. Go buy a P1X. You too can trap 175 mph in your full weight car.

Everything is impossible until someone does it

@Angrey

stock unopened Coyote engine record is 8 something at like 155 but that doesn't mean everyone is going to do that on their stock engine

 

[80FoxCoupe]

I got it.

Here's the summary. Go buy a P1X. You too can trap 175 mph in your full weight car.

If you have a car like Moore's, then you will be close. Your car, not a chance. Again you are grouping an oem like setup with a prepared car with the intent to race, and win.

Just cause you wear Jordan's don't mean you can dunk.

Wildly overspun blower, super secret HIGH oxygenated fuel, race weight lighter than a Honda Civic.

Only way it happens with that impeller,.

It's overspun when it breaks. Fuel spec in class rules. Weight spec in class rules.

I don't understand why people are getting bent. If someone was so niave to think they could slap some race car parts on their car and repeat the results of a record holder they have no idea what goes into getting a car to that level. This is no different (well maybe even more complex) than the crazy NA records in the same platform. It would be ridiculous to think I could do a FBO NA coyote and repeat the results of the record holders. Sure in all cases the potential is there to repeat the records, but open up the checkbook and be prepared to spend the same money and time those folks did. Same is true for pretty much any record, if it were easy it wouldn't be a record. Also, doubting the cars weight as measured by a professional racing organization. I get it people cheat, but changing the gravitational constant is rather difficult.

It's funny there are people that think this car didn't actually have a P1X or weigh more than 3100lbs

The weight had to be checked after every pass and win. (Since it was a class legal race car)

Do tell....
What wheel HP does it take for a 3800 lb car to trap 175+ MPH?

Probably around 1,500....

Best part, she had to dial in the motor perfectly, because she could only run the "class legal" pulley combo on the blower. So no crazy over spinning the blower, had to make the power with the engine combo, and engine RPM.

But at least it has "total street car stuff" cuz everything in the photos looks "street car", in the same way that an F-18 Super Hornet is just a "passenger Jet"

This is her new combo, which is yes... very much "race car"

So where is all the weight coming from? Did they add 500 lbs of sandbags to the trunk

What's the size of the motor and the fuel?

What's the RPM limit (i.e. are you overspinning the blower or within the warranty limits).

This is the "new" combo in the photos... and YES she added weight to "make class weight" with the old combo. And that weight had to be checked after each pass/win, due to it being a class legal car.

It's curious why one would need a 10 rib on a P1X. At what pulley size do you start getting slip at typical coyote redlines?

It was an 8 rib for a very long time. She did 10 rib later on, just to keep any chance of slip away.

Wildly overspun blower, super secret HIGH oxygenated fuel, race weight lighter than a Honda Civic.

Not really, cause she wasn't the only one going this fast with a P-1X. Stacey Roby did as well. They aren't just slapping a blower on, calling up a mail order tuner and putting E85 in the tank.

Both have very well built motors with a lot of compression, and very well dialed combos.





At the end of the day, it was a HEAVY car, with the same bracket, blower, belt that every ProCharger STG2 customer gets...going 7's .

NOTE: She did build her own large air-to-air intercooler, cause the ProCharger STG2 unit is pretty tapped out around 1250hp.

The best part about this cars owner is....

- She builds it
- She tunes it
- She drives it

Pretty freaking rad!
