Comparing Throttle Bodies (Harley Stage IV vs HPI) | Shop Talk Episode 9 

Can you imagine if Harley would just ship out the new bikes with the best parts to start with. I am burned out on spending thousands to get the power they should have had in stock form.

You guys are wrecking my sleep habits. Up to 1-2 watching your videos. And some watching for the 3rd time. Nick and I have spoken numerous times. Look forward to visiting you next month!

Good info guys. Keep the good Videos on performance coming !

New to your channel, but love all the videos. Keep them coming

Just put 55intake 475 cam chest stealth air cleaner power duels all S&S IN 107 22 STANDARD. Dynojet power tuner. Picking it up the 19th .. wish me luck ..

Branch & O’ Keefe and RB Racing! I gotta hear this thing! 👍

Thank you for all the information you provide, love the videos. I can't afford to start braking parts on my bike pretty happy with the upgrades I did, please let me know what you think. 2019 RGS with RS468 cam SE air Rinehart 2 into 1 Thundermax tuner. I ride very aggressive 😉

Like hearing about all the differences in the screaming eagle and the aftermarket. Getting ready to start building my 107 and want to get the most bang for my buck

The HPI costs around what? Well done video. Explained very well I might add.

Moonshine Harley, does either the 64mm SE or the 62mm HPI eliminate butterfly valve clapping/chatter/knocking that comes when you put a cam in like an S&S 475C? I put that cam in ('20 Road King Special, 114) and now have that butterfly valve knocking and am wondering if an aftermarket throttle body can make that noise go away or lessen it. Thanks and love your channel!

Just subscribed and am addicted to all your vids 💪

will harley m8 air cleaner kits bolt right up with the HPI and fuel injectors ?

Cant wait for the next vid ! Im dyin over here

Nailed it on the explanations!

That bike behind them though!

Lol. Calipers are +or- .002 from the factory. 👍🏻. Lots of info. I like the HPI throttle bodies. Which I think I will be putting on my bike.

Australian Performance Engines APE ,Manufacture a 55 mm CNC Intake manifold Producing a 150 HP and 145 lbs coupled with a 6.2 gps Injector.

Screamin eagle 131 heads with the HPi what’s your thoughts and what size total for it 62mm set up as 62mm? I’m going with Klock Werks Outlaw 2:1

Finally a video from moonshine I was able to watch. Was about to click of when they said the idiot was not going to be there 🤗

Thanks Fellas! You get any calls from da ladies wit dos phone numbers?

I am wondering about the trask turbo system. Are they actually worth the cost of the turbo? And what kinds of mods must be done to the entire drivetrain? I would imagine you would need stringer internal engine parts and maybe swap the belt for a chain, and some other things that come with stock bike.

Do you or Harley warranty everything you do?

Do you plan on releasing the dyno results between the HPI as is and Okeefe ported TB? Thinking of using the HPI with a set of match ported and blended SE heads on a 124” @ 11.5:1 with a TTS250 or Tman 234 cam. Very keen to know if there was any significant differences between those two TB.

I recently picked up a 64mm SE TB, I only paid $300 for it. The HPI unit is just too expensive, especially considering that it still uses the oem throttle servo motor. I suppose if you're building a big ole mountain motor or something you could justify the added cost.

@moonshine 02 ultra 95 big bore kit,635 cams ported and polished heads, have a 06 tb on it right now,what would you recommend for tb size

A larger throttle does not hurt low end. That plenum could certainly change the flow rate and velocity. A larger throttle body would make tip in throttle much more aggressive though. That little bit of difference isn't changing much anyway. 62mm will flow way over 150 160Hp.

Man you guys are pro's wish i lived there and had you guys build my Harley.

Every show the dyno numbers on these? I'm getting ready to do Branch heads with the 62 mm TB on S&S 131 jugs., S&S 550 . What pipe did they use. Is Supertrapp's 2 into 1 good ?

HPI are the best and made right here in the USA, been using them since 03

Curious what pipe you plan on using which can make a big difference as well.

Outstanding video. Thanks for the truth - instead of the million opinions you get on the forums.

Moonshine what you guys think of basani road rage 3 for baggers as far as performance?

I love the stuff you guys are hitting on/I suggest though that you use a 3 point digital bore gauge not a caliper to measure bores.i work in the CNC world of +\_ .0002 everyday and would slap a bitch for checking diameters with a caliper.other than that you guys have a cool gig rolling (keep it up)we out here depend on that knowledge your putting out

What do you guys think about the SS 55mm aluminum throttle body to replace the plastic one on my 20’ 117 CVO with an SS 475 cam and Khrome werks 4.5 mufflers with louvered baffle and fuel moto 2/1/2 head pipe

Were can i get the red tb

What air cleaner would work with it? I have one similar to one on bike behind you but it's an HD performance part when I did stage 3?

Results?.?.? Which made better numbers?…

Heritage or lowrider s. I can’t decide

Dial caliper reads 1.780 diameter...Pronounced 1 inch 7 hundred and 80thousands. You guys are saying...1.078 dia..... Pronounced 1 inch 78 thousands.Almost 3/4 inch diff. I play a machinist on the interweb LOL Love the channel!!!!!!!!!!!!!

so what should I use with a 110 tire shredder kit 🤔 👀 😳 HD NEIL AKA THE KRONK

Is the bike done yet? I'm not seeing it anywhere

I need all the torque for my 114

What size throttle body comes stock on the 2018 Heritage Classic 114 Anniversary edition? Mine already has the Screaming Eagle Ventilator Air Kit... If I switched to something like the HPI 62mm throttle body, would I be able to keep my existing cleaner or would I have to buy something specific to fit the HPI model? I'm looking at doing a stage IV upgrade with the S&S 114 to 128 Big Bore kit, along with the S&S Camp Plate, Oil Pump, 550 Gear Driven Cam, Lifters, High-Lift Valve Springs and Tappet Cuffs. My focus is on as much low-end Torque as possible. Do I need to upgrade the throttle body as well, or is the stock version on the 114 big enough? Also, I had new lifters and push-rods installed when I got my Stage 1&2 done last year... but that was for a TTS-100 Cam... Should I replace those again with S&S specific parts? Any help is appreciated!

Shake - N - Bake!

i subscribed just for the ricky bobby reference

Did Aaron used to be at Kutter?

Its pretty widely known that a smooth surface does not flow air over it as well as a surface that is not smooth or textured. Example: a golf ball, offshore racing boats hull design, 24hr Le mans, formula 1, and many other markets where science dominates "opinion".

Ride 2 up tour pack on it and I rode like a stole it a lot LOL hahaha You die once, but love every day might as well live it and enjoy it.

Dimple the flow path like a golf ball. Makes everything better... Flow, velocity, and turbulence.

Fkn beasts brothers

You guys should do shows on TV like horsepower TV do twin engine builds I'm sure you will have a lot of ratings a lot of viewers and make sure the host is a fine women that doesn't mine getting dressed up looking fine as hell that also helps there is no shows like this Twin power TV is a must plus help benders sale products and Harley's to i want a new bike for my wonderful idea street glide with 131 build i like hogs and can be the first show

So your saying you have a smaller head.😆

Bro 😎 come on it’s not Jamey it’s himeh Jaime jaimito

good video..... let Mike do them! you guys have terrible acting skills! Love your channel!

"Cams and intakes are a black art" Uhhh... no they're not.

F me I guess.

Never understood why you'd spend all that money on the bike to begin with and immediately start looking for power that the bike should have had in stock configuration.
