AN EXCELLENT UPGRADE TO IMPROVE THROTTLE RESPONSE AND TO YOUR ECOTEC PERFORMANCE.... IS TO REPLACE THE OEM STRAIGHT BORE WITH A TAPERED DESIGN. THE OPENING AT THE THROTTLE BODY BEGINS AT 69mm DIAMETER....TAPER TO A 60mm BUTTERFLY.... THEN OUT TO 62mm TO MATCH THE INTAKE MANIFOLD OPENING. THIS UNIQUE DESIGN CREATES THE IMPRESSIVE VELOCITY EFFECT FOR IMPROVED LOW RPM AND MID-RANGE RPM POWER....THERE ARE NO COMPUTER PROBLEMS....NO CODES....NO LOSS OF DRIVABILITY.
WITH THE 60mm THROTTLE PLATE.....THE THROTTLE BODY AREA IS LARGER THAN STOCK.... FOR AN INCREASE IN HIGH RPM FLOW VOLUME.
THE BIG BORE THROTTLE BODIES ARE PRECISION MACHINED TO PRECISE TOLERANCES TO PASS OUR QUALITY CONTROL STANDARDS.... THE THE OPENING OF THE THROTTLE BODY GETS A TAPER THAT BEGINS AT 6 DEGREES THEN 3 DEGREES. THE NEW LARGER BUTTERFLY PLATE IS MADE OF BRASS AND IS CAREFULLY FITTED TO THE THROTTLE BODY BORE TO ACHIEVE THE PROPER SEAL FOR CORRECT OPERATION AND PERFORMANCE.
sounds correct to me. i personally wouldn't get that unless i was running a turbo or a supercharger. Ive read some people use them and get more hp up higher at higher rpms.
well i will be running a turbo so ... this guy doesnt ahve these all the time
For a turbo setup, a straight-through BIG bore TB would be more beneficial. However, for a non-FI motor, the tapered design acts similar to a velocity stack, increasing air velocity. Not sure why they'd use a brass butterfly though...

better a delay than a disaster.
Brass Butterly....?../\/\..Agreed!

well why couldnt they do a 69mm all the way threw it?
this would not be really effective for the air velocity!!!
so just stick with the 62 big bore tb then huh
69-62-60 is ok for N/A, I've heard good thing about reveco. Having a 69-69-69 would be a waste cause you'll lose air velocity, the air would just enter at the same speed. The way the reveco or any good throttle bodies are done is to help the air getting some speed when entering the manifold. With an N/A car you'll lose some low end power for sure but gain some top end. It always depend of your plans and where you want your power band!!!
Its 69-60-62, I have one. I will be putting mine on ebay soon, need some extra tax money

why get a bigger throttlebody? you do know GM has a 440hp crate 383 that uses only a 59mm throttlebody right? imo 59mm (eg. the 2.3L) is the biggest i would go, even thats on a heavily modified engine..
** unless its boosted ** then i'd go bigger.

well if i get it and then fianlly get the turbo will this tb make me lose any power?
^^^ Firefighter...I would be interested in your Revco TB unit, I've got the RSM right now...maybe it would improve my low-mid powerband? How much you lookin for.
Silver Stripey makes your Day!
silver stripe if you get that tb what would you take for the rsm tb?
^^^ ^^^^ RSM TB killed my low end too! Would a reveco be a little better over the RSM one or not? Any suggesstions?
Nick - Ill let you know...depends on the answer to my last question.
Silver Stripey makes your Day!
No set amount, I am just going to put it up on ebay.
