V Rod Muscle turbo speeds?

I'm wondering how fast a VRSCF would go with a turbo kit? I understand that the stock bike does 0-100 km/h (62 mph) in about 3.6 seconds. I'm not interested in outfitting my bike with turbo: 3.6 seconds is plenty fast for me, but I am curious about the performance numbers. Also, would a turbo kit ultimately shred the engine by getting it to perform at a level beyond its design?

No turbo kits do not shred the engine...the top speed will not change no matter how much power you have...not sure 0-60 would change much...but 30-100 sure is a lot funner!

Standard Trask kit is like 8psi.... however I've noticed that the boost is very temperature dependant..... on hot days it doesn't seem to get much past 6psi though.

It gets hot here in NC and never had a problem getting 8lbs on a hot day. I'm now running 10lbs with Destroyer injectors.

There is really nothing to go into. Power does not change gear ratios.

A stock Vrod running at 9k RPMs in 5th gear will be going the exact same speed as a Turbo'd Supercharged, bigbore Vrod running NOS at 9k RPMS in 5th gear.

Now if the OP wants to know how much faster will a Turbo bike accelerate compared to a stock bike...here is an idea...

Mine is at 6psi and at 150mph realy bad speed wobble. The bike is still pulling hard so I know can go much faster have to first overcome the wobble.

Greg...
I have a 2009 VRSCWA and I am interested in the Trask kit. I would like to chat with you and get some info. Also, I live in Northern VA and could drive down to see an actual set up rather than photos.

Troika,

I have a Trask turbo on my bike in South Riding, VA. Let me know when you would like to see it. I would have done this much sooner if I had been able to actually see and ride one (I had many questions and was just not sure it was something I could handle working on). Rod and the Killer Service Inc guys helped me with the install. I have since taken it off and on several times doing maintenance (Rod is all about showing you how to do it yourself).

Iknosp... Thanks for the reply. Sure, I would like to see your VROD.

He never mentioned changing gear ratios. A stock vrod running at 9k will be slower than a turbo vrod running 9k (in the same gear) because of the increase in HP from the turbo. compare it to two identical snowmobiles. Both running 1:1 as a final ratio. Snowmobile A has 140 hp stock and snowmobile B has 240 hp with a turbo. Both are running at 9000rpm. Assuming that the torque values are consistent with the hp, the turbo will be faster. A better test is just put two VRODs side by side at 9k in a drag race, all other things equal (beside the turbo on one) and the turbo will be faster due to the increase in HP that is created from the turbo.
