I a exploring the idea of having Trask Performance add one of their big twin turbo kits to my 2011 CVO Road Glide.  While I don't race or hotrod my bike, I like power and torque.  I am trying to determine how/if a turbo affects reliability, longevity, rideability, exhaust noise, heat, etc.

I'd really like to communicate with someone from Central Ohio who has a Trask Turbo to see if I might look at it firsthand?  Thanks in advance for your assistance and thoughts!

I have not owned a bike with a turbo or a supercharger but what I have read a supercharger may be a better choice for low rpm power and torque. What made you choose a turbo over a supercharger?

There are several members who have the above supercharger and they have good reviews. I think one member is even selling his 2009 SERG with a supercharger I believe his screen name is WTS, he may be able to supply you with more info if you want to check out that option too.
Here is his bike for sale with photos :

Thanks much on that!  I am contacting ProCharger as well!

I originally got the '09SERG with the intention of installing a Trask turbo system, I liked the fact that it was all on the right side and is pretty much plug and play (which means all the heat is on your right leg), you will have to remove your lowers for either turbo or S/C.

Trask installs them at Sturgis and I think Daytona also.

Trask says they are fine on stock motors. I spoke with a gent in the midwest that had a Trask on an '09 (I had just bought my '09 a month before he put his up for sale  ) and he said that he had installed a S&S welded crank and forged pistons as a precautionary measure.

WTS has a nice ProCharger setup on his '09 and I think he puts some miles on his. The biggest question I have about the ProCharger is, where is the air filter?

Let us know what you decide to do...

was at the local track friday night and there was a sreet glide with a 103 that had a procharger (no air filter) runnning 8 second 1/8 passes, may have had some better ETs if he could get to hook up? he said he had 6k into the set up

I did a little research on using a turbocharger Vs supercharger on the bike.  It appears that the superchargers are harder on the engine and have a shorter working life.  I know that turbos are very common in the car and commercial truck worlds, so they have proven themselves for day to day use.  You very seldom see a supercharger for daily use vehicles ... so that is what little I now know.  Trask indicates that there does not seem to be anyone in my area doing installations, so I will keep trying to locate an end user somewhere in Ohio that I can visit with.  Thanks!!

I have the ProCharger on my 2009 Road Glidge Custom Show Bike. I am very happy with it but it is not a daily rider. I don't know about wear/fatigue compared to a Turbo. See the following link for the Power/Torque curves (near bottom of section).

Hope you enjoy the results, whatever your decision.

Thanks much DH.  I know they work well, but one article specifically said something about not using as a daily runner.  I guess we'll see what my research results in.  It's not like my bike without a turbo is a loser!  LOL

[hrdtail78]

The air filter is in the bonnet (where AC use to be) of the procharger.  To see the gains of force induction on harley's.  It really needs the combo looked at completely, but if you do throw on junk pipes.  140 is still with in reach.  I have a few customers with prochargers.  A 2010 CVO w/ fueling 594, and Drago's Fang pipe is a daily runner.

I would do a little research on Trask as a company also.

[GMR-PERFORMANCE]

We used to be very close to Trask and have tuned , ridden both set ups..  In the end the biggest thing I found myself was the heat off the ex plumbing on the turbo was too much for me for a every day ride. Not taking away from either kit they both made a chit ton of power and are both a hoot to ride. Region may make the choice for you but in 100+ temps anything that puts more heat on the rider can be a killer. Nature of the beast on that turbo system.. There are other turbo systems  out there is the turbo become the choice of pressurized power.

Met and HD Rider Saturday with a 2012 SG and a proCharger. He had just dynoed out at 214HP at one shootout and 180HP at another shootout.
Does seem like a large difference between the two dynos

Were these Dyno Drag setups?  If so, I can see the variation.

I went to a local Dyno Drag with my '09 SERG.  It has 2" Fullsac baffles and their TTS Mastertune canned map.  I've been very happy with the setup for several years now.

In reality, my bike on a true dyno will probably be in the low 90's.  The dyno drag readout set me as much as 110 hp and as low as 97 hp.  Neither of which I would believe.

In these cases it may boil down to the setup of the rolling resistance of the drum and how well one shifts.

Most semi stock Procharger setups I've seen with s dyno readout shows in the 150 hp range and maybe just a bit more.  I would still think that 180 hp is still a bit high.

Just my 2 cents of rambing information.

[grc]

One thing I don't see being addressed much in this thread is the wisdom of trying to produce 150 plus horsepower with an otherwise stock late model Twin Cam, and then expecting it to be reliable.  It's hard enough to get reliability from a stock Harley these days, unless you think reliable is something that manages to go 25k-30k between failures.

If you look at the supercharged or turbocharged vehicles sold by major auto companies, those are highly engineered systems and not just a supercharger or turbo bolted on to a regular normally aspirated engine.  They also have extensive electronic safeguards built into the engine management system.  I'd think long and hard about this kind of modification to your Harley if you plan to actually put many miles on it.  I'm willing to bet the vast majority of these kits are installed on trailer queens/show bikes or barhoppers, not bikes that actually accumulate a lot of miles.

I am with Jerry on this one.  How much time will you be spending in the usable power range of the turbo or supercharger?  It is a major expense.  If you are looking for a once and a while boost of power for acceleration.  Then you might think about a nitrous oxide system also.  Much cheaper and might find some one that has it already in Columbus.  I live in Delaware and there are sever people that have choppers with turbos but they don't ride them same with the superchargers.  They gust take them to shows.  At the drag strip up by Marion there is a harley that shows up with a supercharger and n2o once and a while.  He is using the n2o to cool down the intake charge. 


But I sure think any are cool to look at. 

I am not sure myself on how big the drive is off the crank to drive the supercharger.   I haven't heard of any body shearing the end of the crank off but that don't mean it can't happen...


As for the heat issue with the turbo exhaust.  I have used the header wrap before and it did make a big difference in my application.   However I would recommend not using it on a mild steel exhaust.  It seem to hold moisture and the exhaust life was shorted.  But it sure reduced heat.    Some don't like the looks of it either.   I believe they are making different colors now. 


There is a older guy on south high street I can't remember his name he builds harley hill climbers. 
He may have something down there to look at.

His name is Riser and he is good but obnoxious, LOL.  His son is the one making all the T man performance products. He learned all his stuff
from his Daddy.  Tom is one of the finest machinist in the business.  But I think he is kind of spent his time.  But Id be guessing he would be
up to the task if approached properly.
