Hi there am doing a single turbo conversion have been looking for info on bigger throttle bodies.... what is the advantages of this? i have seen a few names of some floating around on the posts but no actual info that i could find. any suggestions for a 550 600 hp at the wheels build?

Cheers Mark

 

Rotary works just came out with a billet aluminum one that claims power gains... either way it looks really nice.. do a search brotha!


They also have a website www.rotary-worlks.com the throttle body is on the front page in the lower right hand side....

 

On my 700rwhp rx7 i picked up around 50rwhp with one our honed our throttle bodies.

We house 3 55mm throttle body blades in the factory throttle body.

 

I just saw that billet one and that is an awesome piece of gear.

they would have me sold if they had a 120mm one.

 

would that 120mm TB bolt to a stock manifold or made for a custom plenum chamber type???

 

The RW TB is a beautiful piece. I would definitely recommend it.

 

yeah the rw throttle body looks choice. i love the black 1! thanks guys again

 

Are there any dyno sheets with before and after the RW throttle body

 

^ I was just gonna ask the same question! what size throttle body will i need to support say 600rwhp?

 

I think rotary works is a vendor on here.... you should look them up...

 

^ i had a look at there website so i will try contact them through there and see what they can come up with.

thanks

 

I'm not convinced that the factory FD throttlebody is particularly restrictive for normal/street power levels. I've seen plenty of 2nd gens making well over 400whp, and the 2nd gen throttlebody is smaller than the FD's.

 

I'd like to see some back to back dyno numbers between the two. I would think there is a huge difference between stock and ported UIM with RW TB on the FD.

 

This the route I will be taking soon.

any one used the 100mm universal ebay tb's?
they r cheap little over $200,

I tryed contacting rotary-works email, pm & by phone
past couple days with no luck,

I need to get one fast, have event july 9th,

any other recomend for tb?

thnx in advance

 

I was just messing with a rotary works TB the other day. Unless I missed something, you only have one idle adjuster screw which sets the throttle plate angle when closed... I don't think there is an air adjusting screw on the bottom. There's also no fast idle system. It's a single blade TB so you don't have the two-stage design that is used on just about every rotary from the factory. It seems ok for a hardcore high hp setup but I still don't see the point on your typical 350-450rwhp car.

 

Rw is overkill for the street or anything sub 500whp

no cruise control either

 

whats the max hp I can flow with 90mm TB,
I plan 91 or 94mm turbo
thnx

 

Have you tried contacting Rene Franco from Rotary works?

His number is (323)309-4375

He showed me one at his shop not to long ago, might be worth giving him a call and see if he has any in stock.

 

just ordered the the 90mm rotary works tb

 

3x 55mm blades is only equivalent to a single blade 95mm TB, not even taking into account wall friction. Why would anyone need a 120mm?

Marco at ForceFed performance made nearly 900whp on a 13bt with stock S5 manifolds/unported S5 TB, just some food for thought...

 

FEED also has a big throttle body. I have one

thewird

 

this is what i'm running;



of course, will require custom intake manifolds

 

One would think the ports would be a restriction well before the TB butterflies. If that is indeed true maybe we should switch to 4" intercooler plumbing, and aftermarket intake manifolds?

 

who has cruise control?
