    Any new info. on Roe S/C for Gen III

    Hi Onerareviper, We've been testing different intake manifold configurations and charge coolers. With a peak of 6.5 psi at 5,600 RPM, we have a flat torque curve from bottom to top at 614 RWTQ and a peak RWHP of 607 at 5,500 RPM on a stock car. We're not done yet though. Basically, since brand...

    Just had my 2000 ACR Sean Roed - tell me what you think

    Hi everyone, Thanks for giving Ken such a warm welcome. He's new to Vipers, but has quickly found an appreciation for them and certainly enjoys owning one. He's now got a Cobra for sale if anyone is looking for one. Regards, Sean

    What Kind Of RWHP Are You Guys Getting On Dyno??

    Hi Dimitrios, Your numbers sound like Bill and the guys got the car tuned very well, considering those are Mustang Dyno numbers. The only thing costing you some peak HP (say above 5,000 RPM) is the size of the header primaries and the throttle bodies. However, your car is making great torque...

    The VEC2 Update was Easy

    If you have a scale of what voltage equals what AF ratio on your Dynojet WB, we can write a sensor definition and add it to the configuration file. That's what we did using the stock O2 sensors. Just takes a few minutes. E-mail me if you have the data. [email protected] Regards, Sean

    Roe racing fan kit- worthwhile addition?

    Hi Chuck, Your ex-Justin Bell School car had a kit made by a Corvette shop in Orlando. I forget the name, but the guy does a lot of tuning. Obviously, I remember the kits in the school cars as I was both making kits for our shop and doing instructing for the school in 2000. Theirs had some sort...

    The VEC2 Update was Easy

    Hi John, Was that with firmware 5.79? If it was FW 5.78, update it to FW 5.79 by downloading your file at http://www.roeracing.com/support/index.asp . The firmware that we first came out with on the naturally aspirated cars was FW5.75. That was the one that got the V-notch when adding more than...

    VEC2 System Updates With Multi-Channel Logging Now Available...

    The system with a programmable target air / fuel ratio is in the testing phases at the moment. It makes the system more of a "stand alone" engine management system and would not be OBD2 compatible, where the current system is. We'll see how testing goes before making any further plans. In...

    Dyno sheet from Gen3 Supercharger kit testing

    Hi Everyone, Things are finally calming down a bit and I'm getting time to work on the kit for the Viper and Ram again. Below is a dyno sheet from some testing I was doing. The boost varied from 4 psi to 5.3 psi throughout the pulls with major belt slip occurring at 5,100 RPM, causing the boost...

    VEC2 System Updates With Multi-Channel Logging Now Available...

    The current system can log a wideband sensor input, but cannot alter its injector pulsewidth according to the the voltage value. However, testing of new firmware and software that allows the user to program in a specific air / fuel ratio and have the VEC2 maintain it began about 2 months ago...

    VEC2 System Updates With Multi-Channel Logging Now Available...

    Hi JW, The VEC2 works well on engines "when" the stock PCM programming is not optimized. From our experience, the 1992-1995 RT/10's have pretty good factory programming. Yes, there's some power that can be gained, but it's more in the 15-20 RWHP range as opposed to the large gains we're seeing...

It has fully functional real time multi-channel logging, viewing of the active fuel / ignition cells, no "bugs" in...

    Help w/ Roe radiator hoses

    Hi Simms, Sorry to hear of your trouble. Your timeline of buying the hoses a few months ago and having the bleeder seized unfortunately makes sense. I've let two guys go this year for not doing what I tell them to when preparing and packaging the hoses (among other costly mistakes). Call me at...

    Roe or Paxton Supercharger?

    Hi Everyone, To know anything significant about the twin screw supercharger system we're building, you're going to have to wait a little longer. It's entirely pre-mature to be included in a comparison at this time. If you want a SC kit right now, a Paxton SC is your only option. What we're...

    Car will not start..

    If you have power on the green and white wire, but the pumps isn't running / no pressure, Craig is spot on (pump not working or bad connection inside the tank). When you turn the key on, the fuel pump relay is activated and will shut off after two seconds if there's no crank signal to the PCM...

    VEC2 Help

    For those who don't understand what MBN is trying to do, he's attempting to alter his older wiring harness on his yellow Viper to the newer design we're making with no connection into the cam sensor. Normally, we had people send them in to us and we did it here. Only two people (including MBN)...

    AEM Systems in stock and priced right!

    For those interested in one of Dan's AEM systems when using one of our Supercharger kits, we can leave the VEC2 out of the kit and reduce the price by approximately $750. I know of one person who has tried it so far. I don't think any additional power or benefits were gained, other than...

    What causes your exhuast to pop and burbble on deceleration?

    If you do a dyno pull on a Viper and leat the dyno continue to sample on deceleration, you'll see that the A/F ratio goes super rich at more than 10:1 (that's as rich as the meter reads) for quite a while. When you get off the gas, the injectors stay on. If someone with a VEC2 wants to turn them...

    Hi Miles, Drop me an e-mail with what you're after for compressor displacement, or what size the engine is if you're not sure. I'll forward it to one of the guys in Sweden that can hook you up with the appropriate compressor and let you know what drive housing lengths are available. Regards...

    Roe Racing Supercharger Intercooler Pic....

    "Thanks for the update. From my point of view I worry about the heat of the air charge, and overall additional protection for the engine in the long run, and not so much about squeezing out a few extra ponies." Realistically, the two go hand in hand (in my mind). We have the same goal...
