BTR 750 SS \"PLUS\" Dyno Results..................
Hello All,
To help keep everyone abreast of what we are doing for VOI and in keeping with our mission of providing all data possible to Viper enthusiasts, we are testing our VOI cars and posting results here for your review.
This dyno pull was from yesterday. The Viper that made this pull will be at the VOI drags and we will have handouts on the pricing of what options are on this exact car. This is our 750 SuperSnake "Plus" package.
A couple items of interest about the dyno pull itself;
1. This tune up is very, very rich(which hurts horsepower)but will suffice for all of the different air/fuel readouts that we have seen from different customer cars over the years. All of our packages are based upon conservative horsepower numbers and the fact that many users are not mechanically inclined and do not want the hassles of increased maintenance or downtime from parts failures of products used on the edge of their design capabilities. Should a given customer want more power, a simple jet change should result in approx 50-70 RWHP gains above our numbers while maintaining air fuel ratios around 12.0 on most Vipers.
2. The Torque was above 800 Rear Wheel from 3100 rpm through the entire pull! and above 900 Rear Wheel for over 600 rpms.
3. The air fuel ratio peaked at only 10.5 which is very conservative.
4. We terminate all nitrous pulls at <5000 rpm, but it is clear to see that the engine was still making power.
5. The car made 518 RWHP @ 518 RWTQ naturally aspirated as a baseline.
This is corrected rwhp on a dynojet 248 with wideband O2. We use this same facility for all of our cars and customer cars.
We hope to have another session in a few weeks, at which time we will tune for 11.5 - 11.8 A/F by adding more nitrous.(this will not be the jetting combination of mainstream kits that we will offer, but we will on a case by case basis supply these jetting combinations to customers)
We also intend to drag test this vehicle as soon ase weather permits and will post results.
Tom
P.S. To convert these numbers into Flywheel horsepower, the industry standard is 15% which results in;
904 BHP and 1089 B/Ft/lbs. of Torque with nitrous
609 BHP and 609 B/Ft/lbs. of Torque naturally aspirated
