I am considering throwing a blower on my 2000 R/T.
Looking to get feedback from any/all who may have used either the Roe system or the Paxton Novi unit.
Would love to go with a Turbocharger, but too expensive for me at the moment.
Any feedback of pro's and con's of each unit ?
I've heard of ' heatsoaking ' with the Roe unit ?? For a bit over $7k it seems like a good deal and it looks to me like a Roots style blower which from what I've read is a much more reliable way to go.
If I go the centifugal route, not sure who the best installer would be to go to if I decide on the Paxton Novi, as I don't see many Vortechs or others out there.
Also, I never see ATI with any units for the Vipers and can't understand why??
The Vettes, Mustangs, etc, they are by far making the most horsepower with their air to air units ??? Why aren't they in the Viper game ??

Depends how extreme you want to go. On a creampuff, I'd go a simple Roe setup with water/meth. If you want a custom setup with forged pistons and 700-900hp, I would go with a custom Paxton setup.

If I do it, I'll most likely throw the forged pistons in there, whichever option I go with.
What is this ' heatsoaking' I hear about with the Roe units ?
With these motors running as hot as they do stock, I can't imagine how to keep these things cool with a blower, and/or turbo set up on em.
Basically want a daily driver, car show cruiser, that can go to the strip and run 11's flat in the mid 120's without issues and drive it home.

The Roe set up is AWESOME... two of us installed it in my garage in a few nights. Very happy with it. It drives just a docile as stock but has 200 more rwhp now. With the W/M it runs cooler than stock, I could lay my forearm on the blower and it was cold right after a dyno pull!! If you do a Roe you will be very happy considering what you're looking for power wise. Call 1TONY1 for the hook up on a kit.

Great info..
Can you hear the blower upon start up and cruising speeds or just when you get on it ?
I had a Carroll Vortech unit and LOVED the sound...
Fun to fire it up and hear that whistle right away.
Also, with the water meth, I had a similar set up on a previous Vette and had to keep refilling the bag when it got low. Pain in the ass
With the Roe is it to prevent detonation or to keep the system from this 'heat soak' .. Still not sure what the heat soak is.

It comes with a 2.5 gallon tank and does two things. First the methanol is a fuel and adds octane to enhance detonation protection. The water acts as a boost cooler and as mentioned makes a huge difference. Previously the Roe had no boost cooling due to it's location on top of the intake.

Well put.. as for your other question the whistle is barely audible until WOT then it sounds unreal!! heat soak robs power buy decreasing the density of air into the motor. the cooler the air and fuel entering the motor the more power can be achieved with less chance of detonation or (pre ignition). which also allows you to run more advanced timing to achieve the same thermal load.
As a side note, a twin screw supercharger puts out less heat than a typical centrifugal supercharger at 5-8lbs. That may be the main reason the Roe never had an intercooler originally and the base Paxton kits do. The water/meth kit lets guys run more boost and timing than the standard Roe setup/tune.
why no prochargers? b/c the internal step-up ratio is too much for the crank on a viper to handle. want to see pics of the snout that snapped off the crank? that would be mine...
prochargers suck on vipers. That is the F1R or the F2 (which i was able to make fit, BTW).

I knew there had to be a reason.
ATI's absolutley rock on GM's and Fords.
Totally dominate the markets.
i just ordered a polished paxton kit yesterday for my 97 gts. i did research on it and both kits are good but it depends on how much power you want to make at the end and when you want it.
i would have been happy with either. so i went with what i liked. my mechanic had some vipers at his shop and one had a paxton and one that had a roe. he took me for a spin. the roe viper was first, that car was putting out about 580rwhp (not sure how much boost he was running, it was a 98gts with headers and catback) at start up i didnt even know it had a s/c. when he floored it i heard that whine which sounds great!! throws you back int he seat right away power. i thought i was sold on that kit just because of the whine until he took me for a spin int he paxton car.
this car was a 98 gts, with headers, cat back, heads, cam, rockers too. this car was putting out about 680rwhp on the 7#s. when he started it up i heard the whistle sound and at idle you can really hear it. i loved it! we went down the street, it had power on the low end but not as punchy as the roe. you could almost tell when the paxton started making power and thats when you got thrown back in your seat. the sucking sound is very loud with the windows open. i could hear it over the exhaust. also, the blow off between shifts sounded great too!!
all in all, i loved both kits, but the bov and the idle on the paxton is what sold me ive had vorteched vett's and mustangs and i love that whistle at idle sound. also, the ROE isnt carb legal and i live in california so thats a problem.
i cant wait to get it installed!! next week!!
*edit* the paxton is easy to make power, but once you're reaching the 650rwhp mark its time for a new fuel system. which isnt bad, i got priced at 1500$ installed to handle the smaller paxton pulley.
who's doint the install for you on the fuel system for $1500. or was that the install for the paxton ???

im not getting it done yet. john from westcoast viper does the work on my car, right by your area he is going to do the install/tune and i was asking him about running a smaller pulley since i had the forged pistons already. he said with the kit right now i should make a little over 600rwhp with a safe tune and that my fuel system wouldnt support a smaller puley (anything around or over 650) it was just over the phone talk, but he was listing what i needed as far as injectors fuel lines new tune etc. in the end he said it would be about 15-1600$ to get everything to run safely. its something i want to do, but not right now. i want to get new rims so i can buy the stoptech brake system. then i will probably get a new fuel system to run higher boost
