New In The Box Paxton For Sale

[dun4791]

But seriously, a paxton is harder on an engine than a ROE b/c it a) takes more power to spin the blowe (by a factor of 2) and b) it puts a torsional force on the crank leading to many a car snapping the snout off of the very weak viper crank. Some cars faster than others.

How does the centri use more engine power to spin than the Autorotor? I would personally want a centri/intercooled setup before a twin screw/unintercooled setup.

the cool thing about a Paxton, is it doenst really stress the engine all the time, under normal driving conditons, nothing is happening.

being a centrifugal blower its a essentially a belt driven turbo. it uses a step up gear box to spin the blower faster than the crank speed. that gear mulitplication is easier for the crank to spin the blower, and a centrifugal blower is rpm based, meaning it only created boost as the rpms rise, so you can drive you Viper around all day like normal, and never build boost. keep it under 3000 rpms, and everything is the same as before, stab it, and then hold on!

THATS the reason i like the paxton over the roe.

That is a good deal!

That's a shame. My car is coming back from Underground soon with over 900 to the wheels. That's how Underground Racing configures a paxton for the Vipers . But for the record, I will be running an AEM, fully built fuel system features the 3 in tank Garth Weaver pump setup, **** inj, and some stage 3 cnc'd JM heads.

right on man, Underground is awesome, and they know how to do a Viper right and show how the potential of a Paxton! Kevin and KC are first class. if they did your Viper, you got the best!

 

[X-Metal]

That is a good deal!

6000 for a NEW in the box Polished Paxton is a steal, it should go soon! someone should make out like a bandit!

sir, i personally have installed over 75 paxtons-not to mention how many we have done on Mustangs and camaros, and vettes.

if you start running over 18 plus lbs og boost, then you might consinder the limitations of a stock crank. --how many people running more than 16 on a viper??? very very few. just like a $250,000 prostock engine, **** can happen if you push the envelope.

do a search on how many broken crank snouts are out there-then narrow that search to JUST how many of them were done only running the normal Paxton setup of 8psi, and you wont find any, that were installed properly.

you have a better chance of hitting the lottery, than breaking a crank snout on a paxton running the normal out of the box configuration.

like i posted in the dyno run earlier, you can hit over 720 rear wheel horsepower only using 8lbs of boost-and thats the way paxton configures them for a Viper.

i have several vipers and viper trucks that have banged OVER 20,000 plus miles, and hard ones, with drag race weekends thrown in there, all running a Paxton and the owners are loving it.
like any perfomance mod, excercise care and sensiblity when installing it, and or have a qaulified tuner do the work for you. its not splitting atoms, its an engine.

Paxton/Vortech are ISO certified, and the OEM's, Ford, GM, Chrysler all use them for prototype work, and that says a lot about the engineering and capabilities of them as a company.

the cool thing about a Paxton, is it doenst really stress the engine all the time, under normal driving conditons, nothing is happening.

being a centrifugal blower its a essentially a belt driven turbo. it uses a step up gear box to spin the blower faster than the crank speed. that gear mulitplication is easier for the crank to spin the blower, and a centrifugal blower is rpm based, meaning it only created boost as the rpms rise, so you can drive you Viper around all day like normal, and never build boost. keep it under 3000 rpms, and everything is the same as before, stab it, and then hold on!

not that it matters much, but Paxton owners report even getting better fuel mileage when they purposely moniter and drive normal.

Great information thanks! So if you go higher then 8psi then you run the risk of breaking that snout off?

How does Paxton deal with the fuel and tuning issue for reliably sake?

What exactly needs to be modify as car has cutting or hacking goes to installing the Paxton? Also, how much weigh does it add to the car?

you can run the boost up to 12psi and still be just fine, but what do you really want with your car? is 700 rear wheel HP enough? if so leave it alone.

the complete system prob adds 100lbs to the car.

the paxton comes with its own piggy back controller for timing and fuel pump turn on.
it also has supplemental fuel pumps and boost referenced pressure regulator.
it is a complete kit, with Everything needed, all the down to k&n style airfilters.

how much is a pulley for a 99 engine? can it be switched easily? any experiences?

yes, so far still here!

Just so you guys realize what kind of offer this is. I believe kevin at ugr was saying he needed to buy 20 kits or more at one time to get the kits around 6500 cost each. This is a great price. Boomer, you may be able to sell it to kevin, he has dozens of these lined up to do and I am sure he isn't adverse to saving a couple bucks.

thanks man, i will give him a shout. i am not trying to step on anyone with this kit pricing, this is a kit i bought for me-and i just need the cash to cover some med bills.

We have never broken a crank snout with any of our Paxton systems. There are some custom systems out there that require their belts to be very tight to avoid slipping and that may very well be the source of the broken crank snouts that have occurred.

Underground uses a proprietary tensioning system that avoids this excessively tight belt configuration and at the same time prevents belt slip with the smaller pulley's that is common with the stock tension configuration. The fact that we can run a very small pulley with very little belt slip is why our kits make the power down low that we do.

How much is your tensioning system? The web site isnt ready but anywhere I can read more about what you shop sells?

My Roe did 720rwhp with 10# and stock heads.
Ted

Every stock head Roe 10# system I've ever heard of is in the 640rwhp range. How did you get an extra 80rwhp out of yours?

 

[RTTTTed]

I am a friend of Scott and I know that he has a Paxton on his car ('97 blue/white RT/10). You may be confusing him with Bud (also a friend) who has a Roe, nitrous and a whole bunch of other stuff on his '96 GTS. I haven't seen dyno sheets on either one but I don't think they have close to 1000 hp at the wheels unless they have done some things since I last talked to them.

Bob K

Just repeating what Scott told me on the phone (and info in a few emails). He was recommended to me by one of our memebers as having the fastest Viper in the Pacific Northwest. I had a question about my Vec 2. He said he had changed to an AEM when he built the bottom end. I had hoped to see his car at the Mission Father's Day show this summer, but it rained all weekend and he didn't come up. The inso is wrong?

We are hoping the site will be completed in the next 30 days.... If you have any questions call me anytime..
