DYNO TESTED: Ported Throttle Body For Mustang Worth It?

Ported throttle body is another one of those common modifications for Ford Mustang. And while it's super common, there's to be little consensus in terms of real gains. Some claim 5hp gains, others claim 20hp, and some say it's useless. So, we decided to do a controlled test and find out the right way!

To some those numbers don't matter but those that have 2-3 here 10-15there in different parts then it all adds up n it matters...

interesting to see a ported intake where they dont change the actual diameter of the throttle plate. i got a stock body ported on my old car from 55mm to 60mm and bigger plate and it gave a 8hp increase on a 100 wheel hp car xD

When I was a teenager and had no money to upgrade my cars in edition just needing to tinker with something I would remove the throttle body shaft and cut off one side of the shaft horizontally. I would cut off the side that originally held the head of the screws. This side is not threaded. Then I would used countersink screws then cut off the end of the screw making it flush with the half shaft. I would even fill in the countersunk screw Philips slots or hex hole with epoxy that would stay in but I could burn or chip out if I needed to remove the screw.

Preferably you only want to remove the part of the shaft that is exposed at half throttle. When a half throttle the throttle plate would be completely smooth with no shaft speed bump.

Would be interested to see if a 85mm throttle made any difference, it could just be that the car doesn’t need any more cfm

It all adds up for a simple bolt on might be worth it idk. Or maybe just put a bigger throttle body on depending on price i guess. I do all my own port work so definitely be worth it for me.

The only reason I'm considering having my throttle body ported is to smooth airflow in from my 4.6L 2V's ADTR ziptube and out to my Trick Flow 75mm upper plenum. The slight venturi effect of necking down to the throttle blade will increase flow speed, while porting out to the plenum will increase intake pressure. Hopefully, that'll improve throttle response, something the dyno can't measure, even more than adding the new ziptube and upper plenum did.

Adding Trick Flow heads and aftermarket exhaust will add the power I want. I'll need a dyno then.

Mkay, So IF those gains are consistent at running temp and the owner is willing to put the time in to do it themselves then 3 HP is 3 HP, It's better than three less hp...But is it worth the money? Probably not. it might be useful for those trying to keep it stock looking, probably more useful in totalitarian states like California.

Interesting. I just did this to my ISF as well as porting the intake. I am hoping to get around 10-15hp increase with both. (ported intake on the ISF has shown 8-12 hp)

The TB by itself not worth it but in combination with the inlet maybe. Will find out in a few weeks next dyno test.

Thanks for the info. Great channel 💪👍

I'm just throwing in my 2cents but I've been told by other enthusiasts to stick with an 87mm tb for gen 1 and get a 18 intake manifold w/ whatever cold air intake preffered for max power in my gen 1 5.0

I have a 6.2 Escalade with a ls3 ported by chuy TB & manifold

[hobronco]

Would the gains be greater as the engine optimizes its tune for the improved airflow?

[CLka]

Now you gotta do TB coolant bypass mod and dyno stet it. I have seen on some ls1 cars 6hp gain.

[georgedomse]

That's well within the margin of error...

The hump or convergent duct acts as a ventri. The engines stock throttle body is sized to deliver the engine requirement for CFM. The design uses physics to speed up the incoming airflow right before the throttle blade. This allows for crisp throttle response and moving the airflow at lower RPMs. Do not oversize a throttle body or it will make it a dog down low in the RPMs

[harrym]

You get those differences between runs any way's. The NA engine has max its power input. Now put that on a FI car and your talking gains.

Can I install two on my truck stacked to get more? Asking for a friend!

[tjwise]

Good video definitely not worth it glad I didn’t waste money

[chrismadison]

I would like this throttle body, on my Crown Victoria (1998) do you have this available?

[jacecrain]

what if i installed this on a gen 2 with a 2018 manifold

[Angry-Little-Fish]

Will I did it for my gen 2 and supercharger it works but I run out of gas quicker 😢 in my f150 1000hp
