Drag Racing Tech - how street able are 4150 tb

just built a me a 408 stroker with tea stg 3 5.3 heads etc. and want to know how good are the 4150 tb on the street i want to be able to drive it around town and to track 45mins away..so 4150 tb or arrons 92mm elbow and tb on my ported super victor jr intake..

I don't have one yet but I think it's like any other throttle body setup the drivability is in the tuning

deffinately go 4150 over an elbow, especially a low profile one.

ive heard people say that the 4150 tb is only good for track not really the street

It's in the tuning. They're fine for the street.

Anybody running the 4500 ??

4150 is streetable. I DD mine. If the tune is right then everything will be fine. Feels kinda sluggish at lower RPM's compared to a LSx style intake but it's not bad at all. No bucking etc. Mine is speed density tuned. I would reccomend an extreme velocity elbow for when the car sees street duty but take it off when u race it. It makes a huge difference in power.

i think my 4150 and vic had better street mannors than when i was on a fast 90/90. i have like above a hat piped to my stock airbox when i street drive it and then take it off to race

Sounds like you have a progressive 4 barrel (in theory more streetable, since the first half of the throttle is only the primaries.

who makes the progressive 4150

who makes the progressive 4150

The majority of them made are progressive.

The Accufab/Fast TB are the best. I have a 4500 on my car and it is great and a 4150 on dads drives like a stock car.

how is the performance of this throttle body ?

any result?

It is not just put it on and the car is xx faster. You need to make the hood and airpan work with it.

They do work well when done right

PM thedudez (Wes) about that. He's very knowledgable about the 4150 setups!
