Exactly. The end results are the same. You are really only shopping for characteristics.

 

I'd rather not rev to make power, that's just me. I also should state that I went back to 3.55's from 4.10's after losing the Procharger. I'm also on street tires. Michelin Pilot Sports.

I still say the dyno sheets don't lie. The Whipple pulls hard to redline. The more I drive it the more I see that. The Procharger only pulled hard from mid to top. That made the top seem so strong. We took my boy's car out 2 days ago and tried some different acceleration tactics with the Procharger. Then we took my car out and we both agreed that when cruising at 4000 rpm's staying at 4000, both cars pretty much felt the same from 4000 to redline. The centri bottom end is weak making the top seem (and is) the show stopper.

I will admit, you can push more air into an engine than you can suck into one. That's a quote from Art Whipple..ha ha

 

When you say the procharger only pulls hard from mid to top and that made the top seem strong thats where you are when your WOT , mid to top right Unless your pulling from one gear at a lower rpm theres no difference

Well all this info is very compelling. As a newbie it is interesting to see how everyone is all pro Twin Screw and anti centrifugal - In my day is was the exact opposite.

And in closing no one really gets behind a turbo kit but they all agree it makes the best power and torque.

Why is it that there is no group of Mustangers that circle the wagons when it comes to the turbo?

 

Welcome to the site.......

I have a hard time believing that the Procharger couldn't beat the Whipple on overall horsepower....... what boost levels, etc. are these numbers supposed to support?

 

Correct me if I am wrong, but I've always thought that in overall efficiency the centrifugal wins.

 

It does.

 

HUH??... I thought the T/S was more efficient.

 

I have the Saleen SC at 8+psi, drive on street tires and drive in the rain.

Pay attention and you are fine.

No big deal.

 

I'm the first to say that if I was hitting the track regularly I'd go with the Procharger. For street driving and an occasional trip to the track I'll take the Whipple any day over the centri. I should know, I've had both on my car and that's my opinion. The bottom end power is freakin' huge. No centri or turbo is going give you the bottom like a twin screw. I have 2 other turbo vehicles, so I have some experience with this. I know the turbo will peak out with more power and torque, but I prefer a big block feel like I stated before.

Tom281, if you look back on the last page I originally posted the Procharger and Whipple #'s. The Whipple is at 10.5 psi. The Procharger was at 11 psi.

2005sonicBOOST, You're missing the point. Yes, if I'm running the **** out of the car the Procharger is one bad mother. While running the car hard it was the ticket for sure, but my Procharger produced 1 psi at 2500 rpm's. The Whipple produces 5 lbs at 1500 rpm's and NO, I'm not revving the **** out of the engine through every gear while heading down the road. The Whipple just added another dimension and that's not debatable, it's an obvious, radically noticable added dimension that the Procharger lacked while I was driving normal or with some mid level aggression. The Procharger HAD TO BE SCREAMING for that kind of pull. You guys just would have to feel the difference for yourselves, then form your own opinion. I have mine and the experience to back it up, not to mention the dyno sheets.

 

The thing that shocked me about Anthonys Whipple vs. Procharger comparison numbers was that at half a pound of boost less the Whipple produced more overall power (Hp/tq) then procharger all through the powerband.

His hands on experiance, facts, and overall opinions about both systems has been extremely helpful in me deciding to pull the trigger on a twin screw system. Sure, I have a while to go before I seal the deal- but unless I get an unreal deal on a Procharger D1, or Novi 2200 I will be going with a Whipple, or possibly a KB 2.6H.

 

On the track I'd probably prefer the Procharger because it will give a better 60 ft time due to less traction troubles and still produces screaming top end. Haven't had a chance to hit the track with the Whipple yet.

I'll say this too. I highly recommend Procharger for their customer service and the same goes for Whipple. I had Art Whipple on the phone twice for over 1/2 hour when I had a defective part in my kit. We shot the breeze mostly, but this is the old guy that invented the twin screw. He even called me back to make sure everything went smoothly.

 

I get the point anthony05gt... I like the fact that the procharger only produces 1psi at 2500, I hope my paxton will do the same... The whipple makes more boost at lower rpm's but I don't want 5lbs of boost at 1500rpms for a daily driver... Thats just me though


Edit: The whipple is still my favorite s/c but for my driving style I think the paxton will be a better fit. I have always wanted a turbo and the paxton is the closest thing

 

It's all about what you like. I agree with that. I was referring to your comment about WOT. I'm doing like 50mph in 5th gear and want to accelerate to 65 mph quickly. I don't downshift at all, I'm at WOT and the engine never revs past 2300 rpm's. It's so much more impressive with the twin screw in this scenario. Same goes for taking off in 1st gear, give a little throttle and WOW, it just pulls like mad without revs, yet it still pulls hard at revs. What's not to like?

 

I don't necessary agree with this. A properly sized turbo on these engines spool very quickly. A turbo will make quite a bit more tq than a belt driven blower. Take a peek at some of turbo dynos on these cars.

 

Sorry I missed that!

+1, I agree..... Anthony has always been honest about his stuff- a good benefit for this forum!

 

I agree, a turbo will makes much more torque than any belt driven blower...period. I've never driven a vehicle that had a turbo and the same off idle torque as a twin screw though. I know about properly sized turbos making great low end power and torque. They are absolutely wicked. Some of the fastest modular Ford Mustangs in the world are definitley turbos and just watch the way they launch. It's less aggressive and they have less wheel spin. Once they are moving a bit that sucker spools up and it's all over. Twin turbos are scary though. They can lay some absolutely deadly bottom end power.

One thing is for sure in my experience...When I'm cruising with a turbocharged engine with the tach down low, the engine has to begin to push air through the exhaust before the turbo even does a thing for power. That always takes some time no matter what set up you have. The exhaust spins it and you need exhaust pressure before it will spool up at all. Properly sized turbos speed that process up greatly, but it can't be instant like a twin screw.

If I had an 8 second stang with a modular engine, I'm sure it would be turbocharged. Turbos are the king of F/I. There's no debating that. Of course, John Force might.

 

I also heard vortech requires more maintnence than some of the others? is this a myth or is it true?

 

No, it just requires more to install than a Procharger because it shares oil with the engine which means you have to tap the oil pan and plumb the oil to the blower head unit, but that's just install stuff. All blowers are easy to maintain. Centris require oil changes much more frequently, but that's it.

 

My buddy has a APS twin turbo 350Z and it's pretty amazing. The kit comes with ball bearing garrett turbos that spool almost instantly.

I'd like to see Funny Cars run turbos. They would definetly be faster! The rules dictate blowers though.
