Was wondering if there is much of a performance difference between the two styles of S/C? I would like to get a s/c soon - within a month so i would be able to install and test over the winter. I would be doing an install without help of a certified dealer... i do have a shop that works with drag racing cars so they would have a good idea but would a certain style be that much easier to mount?

I'm keeping everything stock (internal) on my '06 QC but i am also going to purchase headers/mids/exhaust/VEC II/ and CAI if i go paxton. I'd also like to drop it 1.5/2.5 while i'm doing all this.

My goal is to end up near the 650-700 rwhp range, i'd like to get there while staying stock... there just aren't any reputable Viper techs or shops anywhere near here, so i wouldn't trust too many places to start replacing internals!!
 
Please check the Mikey thread!!!:) Sorry to Ho around...but I'm doing it for what I believe in....I know you guyz understand!!!:) Thats why I'm Krazy......
 
You have asked a tough question. Come by the house Sunday...we will have two Paxton's and one Roe here to look at!

Lots of issues revolve around what goals you have. There are supporters of both approaches. The Roe is very new...mine was the first on the streets, and I only have about 800 miles on it. It was designed as a street machine, and has only been on the track twice, both times with horrible traction issues. Watch for NBT to solve the traction issues, and 1fast400 has the monster Roe installation that has run in the 10's in a QC. The twin screw in our trucks is cutting edge technology and there is a lot to learn.

Many people have the Paxson and most are very satisfied. It is the most tested and installed. There may be 30 or more installations in our trucks, many by very techically oriented people. There are lots of threads talking about problem solving and setup.

In either case we all agree, the tuner is the most important factor. "Good tune=Zoom...Bad tune=Booom.

Then there is the appearance issue...some like the top mount (traditional) look, some prefer the side mount (kinda like the turbo) look. The Paxson has lots of "bling" possibilities, The Roe options are still to come.

I have a feeling that the Nationals this year will be really fun when we have a little fun running SC's against one another...there will not be a winner...too many variables...but it will be a great good natured competition with lots of fun.

Get one or the other and join us....by the way, welcome to the nicest place on the web!

Please excuse my long posts...we academics tend to lecture and go on and on about nothing...

:dito: IF you get the chance... drive them both. One may trip your trigger over the other.:dontknow:
Have fun with it. :D
 
If your looking for flexibility I Would go Paxton sinply because there are alot more choices for tuners. Although I LOVE the sound of the Roe/Whipple setup. Its more pronouced.

Yeah that's my problem being so far away i would never have a chance to drive any or even get a look at before it would arrive at my doorstep. It's hard enough to find other people who even own/drive their trucks up here.

I guess i should have put too that this truck will see the track maybe 1-2 times a year, the closest track is 2 hours away.. so it would be a street beast, leaving traction as an afterthought, i wanna break traction :rock:

I like the top mount style too.. but what kind of availability is there on the Roe s/c? Would i even be able to get one within the next 6 months, lol. As for blowing it up, i don't think i'll push it that far. I'm just looking for a good boost so i can take most vehicles i meet on the road. If i ever have the need for speed i can hop on the Motorbike, it's insane!!
 
What I see as one of the major differences is maximum safe boost levels, and subsequently maximum HP. Although you can raise the pressure on both designs, only one allows for thermal intercooling. Obviously our engines are very susceptible to heat and detonation damage, so this is a real factor to consider (depending on your goal).

Yes, the Roe TSTM does include chemical intercooling, but you can have this AND the water/air intercooling included with the Paxton, allowing higher boost with less risk of detonation (Although the TSTM could be side mounted to allow for an intercooler). Therefore, the Paxton should be the peak HP winner every time.

Power "under the curve" advantage goes to the Roe. If you compare the output of the two, the Roe is certainly building more power earlier. However, if you overdrive the Paxton higher AND your engine can stand the higher peak boost, you should have comparable power output at the low end, and higher output from there on up with the Paxton, as the centrifugal design's efficiency rises with RPM. It has been mentioned that this lower output down low on the Paxton can actually be a benefit, as traction becomes the more limiting factor.

Looks-wise, you gotta love the "I mean business" look of the Roe. Bling be damned, it just looks like a classic hot rod part.

Just my .02 worth...:)
 
Sure you can get a Roe shipped to you within that time frame. Call Dave at Roe Racing. (904) 529-1219, he will ask all the necessary questions...

I'm running 5.6 lbs of boost (very conservative) and it is more than I can handle. I think this setup is ideal for the street...and yes there will be very few street machines that will stay with you from stop light to stop light...but then again maybe in Red Deer there is only one stop light:dontknow:

All of the tunes I have for my truck are "safe" tunes. It can be made to be very radical, but us old farts need lots of error room.

And by the way if you leave now you can be here Sunday to see the Paxsons and Roe in my driveway...
 
IF you are running street tires your gonna break traction with Both systems. If you look at a dyno of the Roe your boost is applied inside a window of abput 4-500 rpms. Meaning that you have ALL of that power hitting at once causing the severe traction problems. With the Paxton its applied gradually over the entire range of power. By the time you hit 5800rpms with the Paxton your at max boost and power. With the Roe your HP is back down at 400 or so HP, BUT the converse of that is at 3500 RPMS with the Roe you are at max boost and the Paxton your at 50% boost. So, like Mike said, its 2 schools of thought but with the same end result.....SHREDDED TIRES!

They are both good systems and I think you should fly to Bradenton Dec 8th-10th and come see which one you like best. Ill be more than happy to let you drive my truck.
 
That's an awesome offer Blake! Deibs, I would be booking a flight asap!
 
Lmao,, i know i would do almost anything to get out of this dammed hell. -18 celcius (Feels Like -30c with wind chill) today going down to -26c by Monday,, that's without wind chill. Although it makes for a great cooler setup!

I originally liked the TSTM for the look factor, it does have that old school mean look to it. This paxton is sounding like a good street machine,, would allow me to keep the read-end and tires stock while still having enough power to make me happy :)

As for the offers i would love to come and see these things first hand, just wish i would have thought about this earlier.. as for the Winter months we are working non-stop in the Oilfield and getting away is nearly impossible.
 
I like both systems. i just think that the Paxton has more miles on it therefore is proven. I like that the Roe gives you all the power on demand but i dont like that it Doesnt address the heat soak issue but with Water/meth which is a bandaid at best. I think running a shot of nitrous is gonna help mike out alot (100+ rwhp with a 50 shot), because its helping with the heat as well as the HP. Well see....Im most likely gonna run motor only at Bradenton unless we get alot more done than I think we are. If I do run the nitrous I dont think Ill be running the 250 shot....prolly a 150 shot. Well see.
 
Dont waste your hard earned dollars that ya made in the oil fields brother:rock:

Have a turbo system installed, much better drivability, much more capable of making tractable hp.

the drivability is awesome, unless you are under boost it drives like a normally asperated engine.

besides the superchargers are wwwaaaaayyyyytoo slow:D :D :p :burnout:
 
Yeah Turbo you say? Should i give Hennessey a call and order a Venom 1000. Maybe i should get a STS on one side and a Hen on the other.. hmm. :D

As for heat issues are you running an intercooler Blake? If so is there a top mount option on the intercooler. Guess i just need to find a vendor so i can get going !

NNNNOOOOOO!!! hennessy or sts!!!LOLOLOL

Heffner or underground!!

yeah Blake has an intercooler, but I dont think its an option on the top mount, but custom ones can be had:D

Not enough for me to be under there and measure when the hood is down!

Sorry, in a smart ass mood. Just took a look...have to look in the scoop...looks to be more than I thought...maybe four inches!

But Turbo wouldn't give you much power off the line.. ? The idea of having a BOV on a V10 would be rather cool.

I thought from what i had read that Turbo's = Boom, i wasn't really reading too much into it though.
