For those of you who’ve gone as far as stage three; what are the biggest pros over stage two? This coming from a 2020 street bob with a stage to torque cam, Bassani pro street duel turn outs, Screaming eagle ventilator extreme air filter, and power visions map. I feel like the stage two is pretty awesome, I’m just wondering if the stage three would be more explosive pick up and throttle response. Meaning less cracking of the throttle for more instant power.

 

How are you liking that bassani setup? I damn near got it for my bike, but hesitated because of how they lose low end tq vs the 2-1.

 

I like it pretty well. It was kind of recommended, and I went with it because I like to look a little better also. The only thing I don’t like is if you lean pretty good and tour slow corner a real carver, You can scrape them. Probably would’ve went to in the one had a known I was going to go a little further into the stages.

 

It is a butt load faster. To me the difference between a stag 2 and stage 3 as far as my build is bigger then the difference from a stage 1 and a stage 2. And my bike is just louder and pounds harder with the extra cubes and compression. My friend had the same stage 2 setup as I had before. And we delivered the same side by side race results. After my stage 3, I walk away from him like he is standing still, even when he has a couple of bike lengths on me at the start pulling from the light, I can real him in and pass him like nothing. Now I have a stage 4 in my Breakout and the addition of a 64mm TB and manifold just helped me move my curve to the right a little still maintaining my bottom end and it is just a freight train. And she liked to pop wheelies on the stage 3.

 

That’s awesome! Not that it really matters but is that the 114 or the 119 stage three?

 

No, it does....lol. It is a 128 S&S at 10:75 compression . I honestly cant stand the mono sound of 2:1 exhaust and the popping without tone the cats on a softail are in slipons and my rineharts have such an awesome tone and nasty bark in stereo .lol. And they don't make any aftermarket headers for 2:1:2 or just for duals for softails I can find only complete 2:1 exhaust kits. I still yielded 126/149 when my builder didnt believe my set up with stock catless header would result as awesome as it did. Is it due to the short exhaust system cuz my curve is flat and the torque comes on early at 2500 rpm its at 135 ft lbs of torque . I got high torque due to the RS 468 torque cam. I did not care about high HP but knew id have way more then stock anyways so its good at 126 and because the way I ride I needed the grunt of torque down low and to the mid and with my setup it takes it to 5500 rpm where the horsepower basically kicks in and at that time or before I am shifting. I am not saying HP doesnt matter but I am not racing on a racetrack staying 4000 rpm and above near redline where a horsepower outfitted cam would work. I am riding on the street light to light , back roads and all I can say along with weight saving because I have a softail from my friends baggers I walk all over them and they have 150/150 builds and live by dyno numbers. Torque caries a Harley.. You could have 160 hp, but if the torque doesn't come on until 3500 or 4000 rpm, your gonna have to beat up on the clutch to stay in the powerband when ill be already gone by by. I am right beside my buddies GSXR 1000 for 150 ft lauches and of course he leaves me but he cant believe how I am there for a little while after he leaves and he is fighting to keep his front end down. I love it. I want to keep the bottom and mid torque so if I go to a taller cam I may go RS548 but I may have to sell out and go 2:1 and the only one I like performance wise and sound is the Burns. It has no baffle and for racing but I hope with my setup I don't lose any bottom.

 

I did a stage III (96 to 103) on my 2011 Heritage Softail and it ran great. Sounded awesome. It had V&H True Duals, V&H FP3, and SE AC. After some research, I decided to go with a stage II on my 2019 FLHSX (SGS) (M8 114). I went with the torque CAM, Trask Assault AC, V&H Raider Slip-ons, and SE Pro Tuner. I also added the upgraded oil pump and A1 Cycles vented dipstick. Couldn't be happier. Great throttle response, runs great and sounds decent. For my money I would stick with the Stage II. If after riding her you feel like you need more, go with a stage IV. Hope this helps.

 

Hi. I look at it this way.
A stage 2 will maximize your current engine's setup: exhaust and intake with a cam install and a proper tune.
Stage 3 is a displacement upgrade.
Stage 4 is a ported polished head upgrade with throttle body and injector upgrade. After a stage 1&2 I had the S&S 106 hot set installed.

I went from a well tuned 96 ci engine with 101 pounds of torque and 95 hp to a 106 ci wit 108 pound of torque and 103hp with a very flat torque response. See Dyno tune graph.
Adding ported and polished heads with a larger throttle body would push it up above 110 pound of torque and 108 hp. The key to any mod is a good tune by a competent Dyno tuner.
I Use a TTS tune interface instead of a piggy back tuner. I'm very pleased with my bike and it's performance.
