ive searched for a while and i cant find out what the benifits of this mod are,
is it worth it to do on an 88 s4

 

You gain some thottle response by removing the plates. If your hard up for HP removing the rod they sit on will gain you a pony or two up top.
Check out the beefy N/A thread, lots of info

You might get 1 hp at the cost of street drivability.

 

thanks that thread is very helpful.
any one have a link to a good write up on how to mod the tb?
also a write up on how to do the emissions delete

 

That depends on how you "mod" the throttle body.
I recently removed the throttle plates/shaft and the dashpot and thermovalve but left the thermowax intact.
Throttle response seems marginally crisper and "street driveability" was affected not one whit.

 

The problem is that most results from this mod are felt using the butt dyno....

 

lol all over this thread.

search - my thread debunks some myths and gives you some legit data.

 

That's only a problem if you want to make hard, quantified claims.

I did it on a whim, just to see what happened.
And yeah, maybe my butt had some hope invested in the outcome.

While the advantage is arguably marginal, the downside is equally so...to the point that I wonder why Mazda bothered with the secondary throttle plates at all.

 

you make horsepower by enlarging your smallest orifice in the 'pump' system. (from an airflow standpoint)

 

emissions would be my guess?

 

that's a bit vague and not totally true

 

Waste of time.

 

check out rotary resurrection's website he has alot of detailed write ups that helped me with all of this

 

exactly

 

thanks man that site is wicked

 

I did it because I was bored. Didn't notice any differences, positive or negative.

 

Benefit?

It's more aesthetically pleasing.
