Procharger pros and cons

[windwolf]

I can only tell you that I ran this bike in the heat of Sturgis, the hottest it ever got was 210 degrees.My tri[ that yr was in temps from 90-105 degrees.
I once calculated that it lowered the incoming air charge by 20-30degrees.
In cooler weather, the intake tube in front of the carb would actually form sweat that was ice cold to the touch.
Not being a scientist, I figured any cooler air I could get would lower the charger temps a like amount. In three yrs it never ran hot. Before building the air to air, I had oil temps as high as 240 after a hard run, ambient air temp and humidity affected the oil temp far less after air to air install.
To me it was a success. windwolf

Thank you for the info.

We have installed 5 or 6 of them from stock set up to 15 PSI and real world 222 hp.. Heat wise , there is not extra that can be felt on your leg etc. However it gets a bit busy with the extra parts.. We have tuned over 2 dozen of these and they do make good power.. Most of them are just basic stock engines maybe a cam and low boost.. Its a simple bolt on for the avg guy and makes big power with out messing with the engine.

Downside look, cost, and yes you do have to stay on top of Both inner and outer belts. Use the wrong fluid on the inner and its a mess to clean up after the blets snaps and gets wadded up..

Clutch upgrade is a must, getting some one to tune it correctly can be another.. But all in all they work well and do produce great power and you cruise on the base motor until you wind it up then the big power hits.

We have done two of them on new harley tri glides with the 103 a basic cam swap and T max tuner.. They have never seen the dyno as we do not have a trike drum set up.. I can tell you that the 3 wheeler will broil the tires with just a bit of clutch and its rather funny to see that ... They pull like a monster and the guys like them.. as well they sell the bike pull the S/C off and re load a base map and let the t max dial in from there.

I say just take your bike to the wrench, let him build you a bad a$$ engine...one without a SC or Turbo and then be done with it....less money, more reliablity.

I've been running a Magnacharger on my 98 FXSTC for over 2 years without any problems. Completely stock except for the cam. I get 40+ m.p.h. on a trip and I don't run in the slow lane. The h.p. and torque it produces make it a blast to ride. It is a little pricey, but the advantages offset that. It looks really sick, and you have a ton of performance with the reliability of a stock engine. It doesn't fall on it's face at altitude like a n/a bike, and I can unbolt my h.p. and bolt it on my next bike.

So............ basically what I'm reading is stay away from the Pro-Charger. Any suggestions as to hop up my '11 103" motor? (cam suggestions are greatly appreciated)

I been running a Procharger on my 120R for over 3,000 miles and haven't had any issues except for shredding tires. With that said, the added "clunkiness/bulk" of the components does take getting use to. I only running 8lbs of boost, because of the 120R crank. I intend on having Frank do some crank work for me which will allow me to increase the boost to 12ish.

Check these guys out:
They make a unit similar to the Magnacharger (in similar I mean Roots type) with some mods?improvements....
Of interest to those that have a Magnacharger is that the folks at Thomson have developed a throttle body and fuel injection system for their set-up which IMO could be modified of ta Magnacharger.Im my quest to run FI withe the Magnacharger I have, I called the folks at Thomson.
I had an extensive conversation with Steve over there and he had good selling points for his unit. Also he did tell me that he would be able to supply the FI system independently.
Another place to look at is Hilborn, they have a stand-alone unit of there own.

Thanks Jbco2: I'm always interested in seeing whats out there. I'll be having a scan for sure. windwolf

I have seen the drive belt from the primary break alot,as well as, the primary chain itself. it then wedged itself under the clutch basket and had to break the clutch basket to get it all out. tore up the billet primary cover and replace it too. it is a very expensive oops if that belt breaks.

I have read the pros and cons and for every normal person theres a nutjob , Working with Star Racing and Procharger i just finished this years project bike with a S&S Star engine and a Procharger the bike is pushing over 200hp on two diff Dynos.

I suppose if all my screws were tight i would have just left the New S&S Star engine alone but understanding the Cons has they have been explained takes the same sense as pulling the arm on a slots .

Star finished a Road King on a Procharger with the same engine iam running with Juice and pulled 300hp. It takes having alot of faith in George Smith and the S&S crew to take the gamble to hit the mark and not explode the engine that i have . All three Star Procharged bikes were built knowing they would be pumped. A gamble maybe shreading a tire in 4th gear some would call stupid.

I wouldn't stay away from the procharger at all!!!! I have had mine on since 2010 (on a stock engine at the time) and it was great.

Don't listen to these guys saying that "it creates a whole bunch of additional heat"...they don't know what they are talking about. A high compression engine will create more heat than a stock engine with a procharger on it. I would take a procharged engine ANY DAY over a larger "high compression" engine. Look at it this way- with a procharged engine you have all of the benefits of a high compression engine (power when you need it) and non of the dis-advantages (additional heat, no need to have high compression pistons when you are running a procharger)

if you look at my numbers in my sig you will see you can get serious power out of them. (my comp. ratio is 9.7:1) I can cruise around town like i'm on a stock bike, driveability is great.

If you are interested call Frank at Dragos bike works..I personally know him and he is a great guy to deal with
