Throttle Bodies

[moddedsixxer]

So I'm lookin at a BBK 70 mm throttle body because I'm getting a blower but I was wondering how important is a throttle body?

Im not sure how it is on the 4.0's, but on the 3.8 cars the throttle body is worth maybe 2-5hp, even with a blower. its not that big of a restriction

 

[moddedsixxer]

oh ok so its really not worth the 300+ dollars that it costs in your opinion?

 

[Grkstang]

You won't see much of a difference... Might have a little power gain, but it's not worth the money.(personal opinion)

HAve you upgraded the rear end gears?

 

[mustangsally1]

you can also go to a garage and ask them to bore your throttle body out it wont be as expensive as a new throttle body

 

[moddedsixxer]

I'm actually getting an 8.8 rear end with trac lok and 4.10 gears and ya its probably not worth it then

The only thing its really going to give you is better throttle response and you may "feel" it on the butt dyno but not really that necessary.

 

[NYstang]

much better putting that money towards a tuner, an FI fund, etc

 

[moddedsixxer]

lol understood and NYStang you know I have an FI fund going

I think Jerry Strannigan actually sells the factory ported and polished TB for the 4.0 on ebay.

I looked, I didn't see it. How much was he charging?

I don't think he has any up right now on ebay but you can email him. I think he sells them for around 70-80$

Jerry's email is plenum1@sbcglobal.net

As an engine starts making a lot of horsepower (500 plus) that when the throttle body will really show a resriction. Dyno pulls have been done to prove this. A 500 hp engine will see a 15-17 HP difference between throttle bodies. You might see a little better throttle response, but thats about it. Use the 3 bills on something more worthwhile. Not to say a T.B. isn't worth the cost, just not at this time.

Jerry did mine instead of buying one from him, better throttle responce from my X-charger. Can't really say any more power because I also installed a cooling mist!
