07' throttle body question

[Lance03]

What size is the throttle body on a 07' Street Glide? One of the guys at the shop that is doing my 103" build, suggested the Screamin' Eagle Pro 50mm EFI, P/N 27623-05. will I get any gain. Is it worth the $400.00

[stix68]

OEM t/body is 46mm I believe.

[stix68]

double post, sorry. The 50mmm SE t/body would be okay to use on the 103, other t/bodies out there, I'm sure others will tell ya. Are you doing head work also.?

[Lance03]

Yes, head work, ported, flowed, bigger valves, S&S 570 gear drive cams,new tappets, adj. push rods, clutch spring. Already had Rinehart t/d, Forcewinder intake and SERT.

Baseline dyno showed 73.4hp and 84tq

call dan baisely he will do your stock one up just rite and will get better flow that the s/e one mine looks great

Just a question - Why gear drive cams on a 2007? Did you have bottom end redone?

Also no expert here but SE 50mm not the best choice and depending on your build, how your going to ride - it might not be needed any way - HPI 51 now thats a throttle body for a stout 103

Your better off going with the HPI!!! If your stock TB is a 46mm,I would go with the HPI 48mm if your heads are good flowing!!!! You can also send the HPI 48mm to Mr.Baisley and have him match it up to your heads & intake!!!

No, bottom end work done. Do you see a disadvantage to running gear drive cams on a 07'?

The existing hydraulic cam-chain set-up is absolutely fine.
No need to spend the extra loot.

I agree with Robby ,Dan Baisley does a wonderful job with the stock TB and it flows better than the SE 50mm too.
The biggest disadvantage to the SE 50mm is the clamps crack OFTEN and create intake leaks....I've seen this several times. The SE Tuning class at the MoCo removed all the SE 50mm TB's from the class bikes because of the ongoing problem with the stainless clamps cracking causing too much downtime in the class room.

Other than the cost, any other problems that I may encounter?

Does anybody make clamps that don't crack as often? and why are they cracking? is it the hardness of the stainless or un-even torquing during install.

The clamps are super thin (weak) at to top closest to the rocker boxes.
Yes they crack with uneven torque, vibration, and improper installation.

Your stock TB will work on your build but if you are going to go bigger, IMO buy the HPI 51mm TB... If you ever bump the size again you won't have to replace the TB...The Hpi TB is a quality product and you can get it for cruise control equiped bikes... HPI TB'S show real world results...

If your crank wheels are not true you could do other damage running gear cams.If your not sure about crank run out, or your not going to address it, I would stick with the chain!!!
