New 2012 Trask 120r Road Glide.... 1500 miles todate with no problems
189 hp / 190 Tq Torque fantastic and comes on early.... Dyno Chart Attached.

 

Nice numbers!!!!!
But why do they having you running so lean??? you will melt that motor. at 11 lbs of boost on a turbo its like running a procharger at 15 lbs10.5.1 motor. And I am a Trask dealer so I am not knocking this at all.

It looks like the injectors were to small and they ran it lean look at your dips on the curve going up. It should be progressive decline like 13.8 to 12.1 at wide open your goes the other way. Is this a stock 120r?
What size injectors?
What efi system?
Is this stock 120r?

Thanks.

 

Bike has dual exhaust, with the probe picking up some back feed thus leaning out the real number..... fist run was 16 to one prior to moving back probe... Nick and Trask team did the entire job, they did a fantastic job on the tune.... Only dip on top side came at the higher boost... The larger number at 11lbs is a about two more than I run on the street... That's about 15hp less.
Thundermax auto tune runs great in this bike as well as the 103 turbo I have.... The 120r runs like a stock engine, at idle, at high temp, in all areas and delivers fantastic milage as on our poker runs it uses the same or less than the 110 cvo my wife drives. I have had turbo's on more toys and race equipment than most, and the tune up is critical and the team at Trask hit a home run on both bikes. Given you are a turbo dealer, give Nick a call for details on the bike... So far nearly 2000 miles and not one issue or problem.... Great set up...

 

Wow bet that's a blast to ride.

 

Holy crap!! That would be insane to ride.

 

what are your riding impressions with the turbo......how does it ride in stop and go traffic and around town? I think we can all see how it goes above 4500 rpm...

 

DO you have a video yet?? I wanna hear this thing!!

 

The 120r from what I can see and hear runs like a stock engine... Idle and up perfectly smooth.... With the turbo, the magic comes that the power comes up quick... as the graph will reflect 120plus torque at 2500 rpm.... The power with the turbo is perfectly smooth and linear. The bike rides like a stock bike only you do most of your driving with 1/4 throttle.... Mileage is better than what my wife gets with her 110 road king.... With the torque, I skip gears and run nearly all times in 6th gear. For ride ability, I have no issues with turbo heat at all.... What I do get is hot air coming from the left to right at the air gap behind the trailing cylinder.... Yet I believe this is typical of Harley's.... As for power, it's great, yet like most everyone, one can never have enough power. I have an identical bike with a trask 103 turbo with cams and trick heads... The power with that bike is pretty much the same only 30-40hp less.... The real trick and magic of a power adder bike is with the right tune up.... Trask and team have nailed this with both of my bikes... I am a gear head, my main ride is a 600hp plus boss hoss.... Now that is crazy fast... It has gone mid 7's at 222mph on the drag dyno in the quarter..... Not sure how quick the Harley would do ???

 

Must be a lot of fun, I'm curious as to why you went with a turbo instead of a supercharger.

 

Past experience with Turbo's and the fact I have not seen a Supercharger system that would leave me secure in long term reliability.... The other huge factor is that the torque comes up much much quicker with the turbo... unlike the supercharger which requires rpm to make higher power.... I would suggest this however, the Tune up is what is most important... I have had lots of experience with turbo's over the years with race equipment... You can break things 1000 different ways absent the right tune up.... Air, spark , fuel must be matched perfectly for long life.... After doing a turbo 103 last year and with 6700 miles with NO problems, I had Trask build me the 120 r.... Right now 1200 miles with NO issues or problems,.... None....
