    Disappointing Dyno Results - Help!

    Mark, your numbers are way too low, definitely outside of any acceptable parameters for a Gen II motor. You should expect 400-410 RWHP in showroom stock condition, without K&N filters. Add K&N filters and you should expect 415-425 RWHP. You probably already know this, so let me ask a few...

    Race calibrated chip ...part# P5007313

    At Desert Venom, we've removed the MOPAR computer upgrade from our Viper racecars. We found no improvement in performance but eventually we began to have problems with starting and idling after we installed the upgrade. Our cars were prime candidates for the upgrade, with free flow filters and...

    New 2000 problem!

    On hard acceleration, if you suddenly lift off the throttle, the fuel pump does not immediately stop pumping fuel. I understand there is a lag of as much as 2-3 seconds. On Vipers without cats, this results in the unburnt fuel making contact with the hot tips of the exhaust pipes and turning...

    Dyno results for MOPAR ECU and high-flow cats

    Sounds to me like your cats are costing you a minimum of 20 peak RWHP. I don't know anyone running the belanger header/exhaust system with cats off that make less than about 460 peak RWHP. You can have the cats flanged so they can easily be removed and replaced with straight sleeves for track...

    why is corvette beating viper at lemans,texas and sebring???and how?

    There is a huge difference between the old factory efforts involving Team Oreca and the private efforts of the Viper team you have seen at both Texas and Sebring. Race car setup, budget, driving abilty, and engineering technology play a huge role in what you are seeing. Some of the Viper...

    Looking for pics of GTS with different colors

    Check out www.trakcam.com for every conceivable Viper color combo ever seen. You'll have to click on the Viper Days events to get into the Viper pics.

    I need GTS Alignment specs

    I'll offer you a range of acceptable values, however, the optimal set-up depends on the track you are at, the type of tires, driving style and experience level, etc. etc. These should get you in the ballpark. Use a tire pyrometer religiously when you are at the track to determine what tweeks...

    Motul 600

    Motul 600 can be purchased directly from Porterfield Enterprises for $89.00 per case ($7.42 per bottle). Individual bottles sell for $8.95. The bottle size is 1/2 liter. The only reason I can see for using Motul is if you do track events..then it is a must. I'd recommend you bleed/flush your...

    Woodhouse A+

    Bobby Woodhouse and his faithful right-hand man, Bill Pemberton got a 99 ACR built for me that nobody else would touch..all black with no A/C or radio. They gave me a great deal and delivered the car to my front doorstep in Tucson. Both of them are avid participants and supporters of the Viper...

    Viper Days at Buttonwillow?

    Spoke with Skip Thomas last night. It appears that we have 11 Vipers, 2 Porsches, and 4 Panoz GT cars for the wheel to wheel race. That would make 17 cars on the starting grid, which would be the highest ever for a western region VD event. Should be way fun! The Vipers are: Woodhouse...

    Viper Days at Buttonwillow?

    The Desert Venom Race Team will be there including Phil De La O, Fat Albert, Ritch Marziale (in his Le Mans GTS-R), and myself. I believe there will be 10 Vipers in the wheel to wheel race group including the 4 of us.

    Will demand for 02's be really high because of the new 03' styling?

    Re: Will demand for 02\'s be really high because of the new 03\' styling? Here come the flames again. GEN I and GEN II Vipers are awesome today, but they will be technologically obsolete compared to the GEN III Viper. The GEN III Viper should be significantly superior in terms of performance...

    ALMS rules 4 Vipers??

    You might as well get used to seeing the Vettes pummel the Vipers in the ALMS this year. Messley and Borcheller in the #45 car are experienced drivers but were nearly 4 seconds slower than the Vettes. Weickardt and Ellis in the #44 car are rookie drivers from Viper Days and were 7 seconds per...

    Awesome Dyno Results on Factory Warranty Rebuild

    I wanted to share the before and after dyno results on my 96 GTS motor. It was rebuilt under factory warranty in January of 2000. This motor is completely stock and has never had any internal engine modifications done to it. The orignial dyno was done on the car on March 6, 1998. At the...

    Transmission Upgrades

    IMHO, leave the stock tranny alone. Those of us who have track-dedicated road racing Vipers thrash the holy heck out of the tranny and I can tell you they hold up amazingly well. You should never need anything more for the street. Dollars are wisely spent changing the tranny fluid on a...

    Shifting RPM

    Ben, you're definitely on the right track. I love your engineering approach....we need more of you contributing to our learning curve. Been here, done this. See if this helps: To correct your analysis I believe you have to calculate the cumulative total force (rear wheel torque) throughout...

    Roll cages

    There's only one kind of roll cage to put in your car: the absolute best you can obtain. This should cost $4,000-$5,000 installed. Be sure you use 1-3/4" X .120 DOM tubing. The best way to butcher your car and waste money is to have someone who doesn't know exactly what you need do the work...

    Big Changes in Viper Days Wheel to Wheel Racing

    Thought some of you would appreciate a recap of some major changes that have taken place in the wheel to wheel race series for 2001. Skip has reduced the number of car classes from 7 down to 2. The fast class is GT1 and the slower class is GT2. For all practical purposes, there is only one...

    Viper Days racers to team up against Porsche

    Thanks for the well wishes Deano. The driver of the ARCA stock car was the NASA Pro series champion in 2000 in our class. He has a 6 cylinder motor that puts out 560 HP. He wieghs 2900 pounds with fuel and driver. He bettered both Phil and I at the last event at PIR. He ran a high 1:04...

    Viper Days racers to team up against Porsche

    Even though we may be arch rivals in the Viper Days wheel to wheel series, a few of us will be teaming up to kick some serious Porsche butt in the NASA Pro Series scheduled for Feb 23-25 at Firebird International Raceway in Phoenix. Dan Downs, Rob Foster, Johnny Yuma, Phil De La O, Fat Albert...

    HRE WHEELS QUESTION

    HRE makes a beautiful looking wheel, however, it's suitability for high performance use came into question last weekend at the Viper Days event. Johnny Weigel had a set mounted on his wheel to wheel race Viper. During the feature race on Sunday one of his HRE wheels broke in half. I spoke to...

    What color stripes to put on Black RT?

    Have some courage? Try a pearlized Hemi Orange! You can go to your nearest vinyl sign shop and bring home some free samples of different vinyl colors (used for decals, etc.) that you think would work. Lay them on your car in different light.

    POLL: After seeing new photos, who likes the 2003 look?

    I'm very happy Team Viper took the styling cues from the next generation GTS-R racecar to develop this new street car rather than designing a street car and then trying to force it into a racecar. I truly believe all the naysayers will be astounded when they see this car in person. Mega kudos!

    After-market Brakes

    The Porterfield R4S may be a great street pad for the Viper, but it is absolutely unsuitable for road course use. The R4 is the proper pad for the track. Bob Stevenson ordered a set of Porterfield R4 pads for the Viper Days National Championship wheel to wheel race. As we determined several...

    Viper ACR

    GTS Bruce, Try setting the rebound on the front shocks to full soft and the bump on the rear shocks to full soft. This will help your launch considerably. The ability to adjust your ride height and shock settings is an awesome performance tool if you take the time to experiment with them...
