Just received my 90mm Rotary-Works TB such a great piece can't wait to install it and test it, too bad it will be a while since the car is still hybernating.

And I thought I was done with this car...LOL..

Here some pics

 

I am very tempted but got too many parts that I NEED to buy already.

Is it longer than the stock TB?

 

It one of the parts on my list during this rebuild.

 

so this eliminates the transition from primary to primary+secondary ports and you lose intake charge velocity affecting low end right? is it significant enough to be noticeable on a dd street car? is it even an issue?

another thing, there are people making crazy power with the stock tb, why change it?

That thread just advertises it for sale, but no performance data/dyno info offered.

 

KaiFD3S- let us know how it is. I was going to get one of these my self.

so your not selling the car.... thats a good thing.

 

It is a long thread with many parts, but one of them is the TB. He tested it on his stock DD car and noticed 10RWHP

Great looking TB to say the least. I just can not decide what the best route to go is. The way I see it you have several options.

1)Modify the stock TB like BDC. It keeps the same size butterfly, and removes some of the obstructions.

2)Modify the stock TB like the Feed unit. Larger butterflys and I guess you could still do some porting work like BDC does.

3)Get the large single TB like above. The single TB has less surface area to slow down the velocity.

4)Leave the thing alone.

I personally do not know what the best method is, and I guess it might depend on how each car is modified, and what it is used for.

I have been bouncing back and forth between these four choices for a bout two months now.

 

Wow. That looks cool!

 

Another month and I get to test this thing.. For me I would rather run this TB than a modified stock one, but that's just me...LOL

This one is actually cheaper than a modified stock one that are being sold.

 

u still wasting money on your rx7.Long time no see budy
kakakakaka

 

I am interesting in hearing the results too. For some reason Rotary-Works is not on the forum and his posts have been removed. Too bad he had some pretty nice stuff on the go :s

 

You can send it to me and I'll test. I'd be very curious to know about the drivability of it as well given the secondary comment.

 

very interesting, im with railgun, send it to everyone to see if we all like it before buying it, your cars hibernating so i don't think she will mind

 

No longer hybernating, sun has been out, just cant punch it too much since the roads are still cold, my intake temps are in the negatives..LOL

 

just go sliding,, learn to keep it under control and you can be the king!!

 

Looks interesting but for the seq twins guys it may not be worth it. Making the low end suffer for a possible 10hp gain at the top end dosent sound good.

 

hey kai what are thos carbon fiber pieces in the picture?

 

Looks like the hood and mirrors.

 

Looks like a really trick piece, I'd love to see some before/after dyno charts!

 

me too!!!!!

 

Sorry guys, there are no Dyno's in this part of AK that I am in, but there is a lot of information on Rotary-Works Website...

 

There is a group buy going on at the "other" forum
