Today October 2nd 2009 is a day for the Star VMax history books.
In preparation for the upcoming www.starVmax.com Drag Fest event on October 25th 2009 at Sacramento Raceway, we have done our near final race modifications and put the first bike through tuning.
We set ourselves a lofty goal of beating 200 rwhps in at least STD correction, or about 195 rwhps SAE. Months of tuning and design have gone into the setup of the bike and we plan to have two very similar configured bikes at the track in three weeks, to see what they can do in the quarter 1/4 mile.
There is still work left to be done to get the final adjustments and touches put on, but today was the day we should find out how close we get to our goal of 200 rwhps. The conditions where ok but by no means perfect. While we had nice and cool weather early in the week, the temps went up the past two days - certainly no record setting air.
What happened next blew the most optimistic predictions of us out the window.
The new setup tops the wildest expectations and we finally have found the holly grail to get the new VMax well beyond 200 hps at the wheel. Not only did we manage to make 200 hps in STD (the older - more optimistic correction factor still used by many), we exceeded 200 hps in every correction factor available on the Dynojet 250, even in raw uncorrected numbers.
You read that right, 201-206 rwhps depending on the correction factor with the best run pulling a solid 201.46 hps (SAE) or 206.01 hps (STD). Not only did we manage to push the top horsepower well beyond 200 hps at the wheel, the torque figures are equally impressive: 126.96 ftlbs (SAE) or 129.84 ftlbs (STD). As always all numbers with the Dynojet smoothing factor of 5 (commonly the lowest numbers reported by the dyno).
These power figures are without NOS, turbo, blower, engine work. All modifications are external like partial exhaust system (utilizing stock headers), Monster Big Air velocity stacks (utilizing the default K&N filters for the setup) and of course fuel tuning & re-mapping.
We are still working on a few additional details but are planning to release a 200 rwhps guide for the 2009 VMax right after the Drag Fest event. Less than $3k into a stock Star VMax and 200 hps at the wheel at sea level are easily possible. So hold your curiosity for the next 3 weeks - we will be super busy setting up two bike with a similar race trim.
If you plan to attend the event, we are happy to help you get your bike setup.
Less than a year ago the very first 2009 VMaxes started shipping. We all hoped to see 200 hps at the wheel at some point in time. I can't believe we finally did it! And not just by a little, as you can see from the attached charts, the bike now makes more horsepower from 7200 rpm up compared to the stock bike at peak. Its stays up solid to 9750 where the engine now produces a whopping 33 hps (!!!) more than stock!
Thirty Three Horsepower - think about that for a moment.
And torque is equally impressive. While the Big Air has a slight dip in torque at 5250 rpm, it still makes more than the stock bike. Peak torque gets made at about 7250 rpm, where the bike pulls almost 20 ftlbs stronger than stock. The bike now makes more than 100 ftlbs of torque all the way from about 3400 rpm till redline. As you can imagine, the upgraded clutch (double spring mod) is a must.
We are getting very exited heading into Drag Fest weekend in 3 weeks. If you are in California, make sure you join us for an unforgettable event with some of the fastest VMax bikes in the world!
