Roe vs. Paxton

[RTTTTed]

Just found the Whipple site and figured I'd post the comparison graph. Here's the link to the page.

I don't know why this graph hasn't been posted before, but ...

doesnt look like any paxton curve ive seen..................

That looks like a "made up" graph - That's probably why it hasn't been posted before...

please delete this thread now, all we need is ANOTHER PAX vs ROE, rught?

That is obviously a BOOST graph not a dyno graph.

You got it. Engines make hp even at idle and the graph starts from zero.

I think the main point of the graph is to illustrate the power curve. That nearly flat power curve is the difference in power output.

That's what's scary about the new ZR1. 620hp right off idle is intimidating.

I have had both applications. I much prefer the Paxton. The boost on the Roe does come in full down low - too low. It's fun but traction, without drag radials, is almost impossible. The Paxton surges after about 3000 RPM like a high performance aircraft. It keeps surging all the way to redline. I can mainatin traction with less driver input with the Paxton. On the other hand, the appearance of the Roe sitting on top of the engine is a thing of beauty. Bottom line - if you have a Gen III with a Paxton, PS2's at the proper air pressure; you launch at the right RPM and shift properly, you should be able to blow the doors off the new ZR1. If you have a Gen IV with filters and Belanger headers, etc, the same result should occur. The new ZR1 is about the same weight as the Viper.

Had both Roe (Gen 1), and now a Paxton (Gen3), and I had a great time with both. I too prefer the Paxton for the same reasons as Bobpantax. Plenty of power......plenty of torque, and pulls scarey hard to redline.......it's a thrill.......no regrets with the Paxton at all.

[RTTTTed]

I bought a set of PS2s. Amazing traction! I think that now that I can actually use all that torque under 100mph ... I'll instal my Nitrous Bottle.

One other thing to consider is all that boost down low takes it's toll on the engine and driveline much more often stressing the motor etc. more that the Paxton will over the long haul.

The flip side to that is my 5 pound Roe can run the 11 turn Gingerman track in 4th gear all the way around with enough grunt to break loose on any corner exit in 4th gear. With my 3.45 gears and Fidanza flywheel, RPMs run from 1800--5000. I can pull a stock GENII/III Viper that runs 3rd gear all the way around this track. That would seem a lot easier on the engine than winding to up redline in 3rd all the time and/or shifting to 4th.

Is there truth to the fact that stock Viper valve trains are a little weak at high RPM...which centrifugal blowers like. I seldom go over 5500 when shifting. Typically 5000-5500 when running hard. My thought is this keeps wear and tear down on the valve train. As for the driveline, my stock tires are my shear pin, the same as it was when bone stock.

Do these assumptions make sense? I do have some back up in that I have almost 80K of our miles on the car -- over 24K on the Roe SC since 5/06. Zero issues. 11K Roe miles on the other car. No issues there either.

My car got the 10# boost at 10K mi. It got trophies at the V10 Nats in Ohio and ran in several other events. I bought it in Aug last year and have put another 14,000mi. on it since then. Now it has 34,000mi. and 24,000mi. were at the 10# boost level.

I love that it makes so much power down low that I can pass, climb mountains, etc. even at 50mph in 6th gear (with 3.08 gears).

Only problem with the huge torque is that I could never lend my car to anyone to drive, it is dangerous.

Well I'm not disputing the facts about the quality of the Roe and it's attributes, the reason I believe what I do is that under normal driving the Paxton car sees no real added wear and I think that even under normal driving the Roe will "stress" the engine etc. more thats all I think. it's just MY opinion.

Thank you,

Thank you,

If whatyou're saying is that more torque and hp put more stress on the engine I'll agree with that.

I'm not saying that the Roe is everyone's choice. There are a few posts that state that near stock bottom end power is what some people want and I agree that the Paxton will allow that and provide big power at higher rpms. I like the flat power curve is all.

It's great that there are options for us.

id still like to find 2 bone stock cars.
1 gets a roe (we can give it an 8 or 10lb pulley)
1 gets a paxton base kit.
let the same experienced (unbiased) driver go down the 1/4 and see the differences.

I nominate 1TONY1 by the way.
