I do not think anyone has said anything about the Centri's not having any low end torque, they just do better at upper RPM levels which is exactly what your dyno chart proves. At 3000 rpms, your getting around 400 lb/ft or torque. At the same rpms, Evowake has 550 lb/ ft and his torque curve is much broader and flatter compared to yours. Now different engine specs are certainly going to produce different power levels but on average, from the dyno charts I have studied, the PD blowers make a very wide, broad, flat torque curve and the centri's make a gradually building torque curve. This is the difference between the two, this is why a Centri may be better for a race car as they do not top out like a PD does. This is why a PD offers more usible grunt at street rpms. Both are very different, not saying one is better then the other, just need to see which one matches up with your wants, needs and goals better for the way you will be driving your car. Both are great, both have their advantages, both have their disadvantages. All you have to do is look at the shape of the dyno graphs to tell you what each blower will do at different RPM levels.

All that torque will be useless if you can drive, have drag radials, or both. Everyone has their preference and mine is a Centri. The whole centri's are better for racing and pd's are better for the street is a silly argument too. It all comes down to driver mod and traction. If your pd car doesn't perform at the strip it's because you can drive not because of the type of blower you have.

First off nice numbers man! I had a P1SC on my last camaro just to validate that i'm not trying to start a fight here. That being said, i have to point out that your statement.....

Is utterly false. Horsepower is a function of torque. if you are generating more torque across a wider range of engine speed, you ultimately have a better performing vehicle provided you can put the power to the ground. Because it is difficult in most cases for any car over 500HP to put power to the ground, this is where a centri. gets a point for most street applications in my book. as far as the PD falling on its face, my car has a cam that runs out a bit up top, and if you want more, build up, pulley down Either way, PD or Centri, you'll have a bad ass ride.

oh, and OP, I went with a PD because i liked the OEM nature of its appearance more than anything. Any FI setup is going the be fun as hell and more than you can realistically use on the street without a LOT of suspension work.

This is also a great option. I've rode in this car and it's a absolute monster. Totally stock looking and once you've found out its not it's too late.

I'm going to tell you the same thing Ted told me...with an auto, the PD blowers will do more instant torque. A Centri will make power up top and not take away anything down low...also, easier on parts.
IMO, Whipple, Vortech, or ProCharger. Pick from those three. You want to drag race a lot...do a centri. You want something easy to install and less lines to deal with...do a centri. Ted's mail order tune is spot on with my car. I'd recommend Whipple or ProCharger and just get it from Jannetty.

Who cares which one beats the other, it can go either way!! Pick the one you like the best and go get it. I have a whipple so I'm going to tell you to get a whipple, Tom, Dick, and Harry have prochargers and they will say get a procharger. Get the one that you like the best (I bet you already have one you prefer) and pull the trigger. I have seen all different types of FI run the same time slips at the track, comes down to driver in the end. They are all a blast to drive so go get blown lol!!!

Before anyone's panties get bunched, I'm not saying centri's aren't capable of making great power. That's not what is being discussed here. 7 to 8 psi on a street machine.....What a YSI does at 15psi is very impressive. If I wanted those boost/power levels, that would be my choice. I don't and I'm guessing the OP doesn't either. Last edited by old motorhead; 04-07-2012 at 05:05 PM. |
