There is a stock Coyote with a Boss intake and a PAXTON (lol!!) making 759/593 with ID1100s and a BAP. That's with pump gas on 12lbs.

It's probably a ticking time bomb like the rest of the 650+hp coyotes, but damn...

I think he shifted like 8 times too. lol.

I like my D1 and it isn't loud. I have heard a few with the straight cut gears and to me it sounds like shit. The fan that came with the kit is louder than the blower.

I'm not interested in having a big horsepower car like you.

Then Vortech/Paxton may be the kit for you. It's hands down the cheaper of the kits. But there is a reason for that of course.

Paxtons advertised hp numbers are typically at the crank and you pay extra for a proper CAI to gain an additional 20-30hp (example http://tiny.cc/1d0knw). Their intercooler is less efficient than Procharger as well. By roughly the 3rd pass, Charger to Paxton, the charger will be consistently quicker back-to-back. Paxtons brackets etc. are simple by design but difficult to install. Both manufacturers offer standard warranties but as far as upgraded warranties go....Procharger's warranty options are sick!

In the end, it all comes down to your interests (what you can & can't live with) goals, and ultimately....your budget.

I can't open that thread. Which blower is it?

Well, I'm open to the Procharger which is why I asked for the price. I'm just not interested in the P1SC headunit though just the D1 like on David's car. I looked at David's car and it looks and sounds good.

The blower Danny is referring to is the Paxton 2200. It's making over 1000rw on Beefcake's street car. It's an excellent option as a base bolt on blower that gives lots of room to grow.

I can't remember the last P1 kit we sold. The chump change it costs to upgrade to the D1 is always a no-brainer.

Yup.

What did it make? Im trying to work out a deal on a stage 2 p1sc kit over on svt. I want over 600whp out of it...

I believe the formula is. Lower pulley diameter/top pulley= X engine rpm= X step up ratio= blower rpm

The max is written on your blower along with the step up ratio. Engine rpm would be where you shift at or the max rpm you want to run. Hope this helps

(Crank pulley size / Blower pulley size X step up ratio) X max rpm= impeller speed

Bold items are simply to separate the math

So how do you know if you are over spinning a blower? I bought my P1
used and it came with the smaller pulley. The shop said it was fine so I didn't worry about it.

I'm assuming a lot here as I don't have all your specs. So your roughly 630whp? I'll also assume you've got headers & full exhaust?

P1SC-1's max impeller (max efficiency) speed is 65k. It should also be a 4.1 gear (step-up) ratio. Your blower pulley roughly a 3.60? And crank pulley a 7.5.

So [I](Crank pulley size / Blower pulley size x step up ratio) x max rpm= 61.5k impeller speed @ 7,200rpm. So your around 95% the max efficiency.

To see that kind of power on a P1 I'm guessing the car is around 12-14psi. What kind of psi are you seeing?

Ok lower pulley is the crank but hey the math was right. I wasn't thinking when I wrote lower

Hey what's the stock crank pulley on a fox. I think it's a 6" but can't remember.

To clarify; the crank pulley in this scenario is in reference to the crank...blower...pulley. In other words...the one that comes with the kit for installation. So, yes, the "lower" is still correct lol

I know which pulley is which. Just because I didn't write it out the way you would like doesn't make it wrong. I was also typing on a phone while taking a shit so give a fucker a break.

So what is the stock size crank pulley on a fox or does a cripple have to measure when he gets home.

The car has 1 7/8" JBA longtubes, H-pipe/ no cats, and axleback. I don't know what size the pulleys are. I will measure when I get home. It makes 10.5 psi. Car is stock other than exhaust and procharger.
