Upgrading P1X to…

[Angrey]

In drag racing, most people are stating the weight with driver. You shouldn't be adding another 100lbs. I know that won't change your mind and you'll still think a P1X can't run 175mph.

Look at the X275 cars. They shouldn't be able to run as fast as they do with the given turbo/supercharger rules, but they do. Your comparing Street car run of the mill stuff to sorted out dedicated racecars. They aren't the same thing.

Most people quote the weight of the car, and if they include the driver, they INCLUDE that piece of information.

So you generally hear/read/see someone quote (3600 lbs) or (3800 lbs with driver). In this scenario, I think you are correct and I think SOMEONE is trying gimmickry to exaggerate the potency of their product. So claiming that it's "full weight" seems more plausible if you include the weight of a driver. In either case, the driver is a woman (and I'm assuming she's not the size of a typical man) so in either case, it's not going to move the needle enough to explain the issue.

Even if you run the numbers on the HP required to accelerate a 3875 lb car to 175 trap, it's still WAY beyond what we've all observed in the real world as possible with a P series blower.

How much HP do you think her engine makes WITHOUT the Procharger?

700-750? More?

On nitromethane maybe. On anything ethanol based, I'd be shocked if it's putting out more than 625-650 at the crank. It's possible, but it would be crazy compression and crazy to the moon revving (both of which aren't really compatible with the blower RPM limits or borderline knock limits on high compression). There's no free lunch here. You can either run low compression and gobs of boost or high compression and boost limited (based on fuel).

Nitromethane and all bets are off, but if that's the case none of it matters because it's not an apples/apples comparison.

Now you think her car runs on...nitromethane.

Already been covered it runs on e

Only 625-650?

Here's a Holbrook racing Coyote engine going 850hp crank at only 7800rpm



Wouldn't be surprised if she makes 700 if not more before the blower. They also did the engine in the runner up for that class that runs a 325 shot of nitrous (and also gets to run a couple hundred lbs less weight, no penalty for a blower)

On ethanol, in the most ridiculous max'd out condition, you could make probably 550 wheel to 575 at most. (for a coyote based 5.0/5.2). That equates to about 630-650 at the crank.

I’m happy with upgrading to the D1X

Wow. What is your mod list? Over spinning the blower?

Forged rods and pistons
Fore fuel system running E85
3.7 pulley probably spinning around 67,000.
This dyno run lost a couple pounds of boost because the belt slipped. Was tired of beating on the car that day so called it good.

solid ass power.

Damn yall are stuck on that over spinning stuff LOL

I know, it’s a habit. Like if it wasn’t a worry why would Procharger cap it so low… ideally, for me, it’s more to gather data. The fact he made that power by barely going over with having virtually no other mods is very impressive.

But how far can you go? I imagine they set an rpm for various reasons - internal bearing limits, impeller wheel load in reference to rpm (its billet so there’s no alloy flex), to excess amount of heat - again we can’t dismiss the laws of physics… compressed air generates heat, but after 65k does it heat up like crazy?

But, again, you’re right. I’m used to hearing about all the horror stories of Paxton 2200SL failing because of it. :/

Just bought a 3.625 griptec pulley. Hope to help belt slip and what’s another 1000rpm blower spin

sure 2000 over max rpm is nothing, but how far can you go? I’m used to hearing about all the horror stories of Paxton 2200SL failing because of it. :/

But how far can you go? I’ll imagine they set an rpm for various reasons - internal bearing speed, impeller wheel load in reference to rpm (its billet so let’s of a worry), to excess amount of heat - again we can’t dismiss the laws of physics… But not only that, I’m used to hearing about all the horror stories of Paxton 2200SL failing because of it. :/

Sweet. Get it! Haha

Once the weather turns I’ll see if the car will hit 1050 if it stays together. Let me know what other information you’d guys be interested in. I tune the car and own the dyno.
