I was doing some research on the Rotary-works Throttle body and came accross this. Not really to sure on the quality, the core sizes sound good, i guess its more or less about ducting but if someone with more knowledge could step it id greatley appreciate it.

im interested in this as well.....

the deal breaker for me is if will be able to keep A/C.... if not..... i cant use it.
Texas summers suck!

 

make sure you guys do the proper ducting to direct flow into the rad/intercooler...otherwise its just gona be spilling air all over your engine bay

get a vented hood
and a proper BOV not the one in that kit

as for the AC...its pretty easy to relocate the condensor and then have some lines made you'll be good to go

looks like a real nice kit otherwise

 

it looks like they are using intercoolers & radiators from CX Racing.

the intercooler obviously has modified end tanks:


$900 seems like a pretty fair price though. but keep in mind these are not japanese-made parts. i'm pretty sure they're made in china, but the quality isn't so bad. i'm using a cx-racing intercooler for my custom stock-mount IC at present.

 

personally, i don't like it....primarily because you can see how much space is on both sides of that intercooler. granted, even a larger one would need ducting but why not go with a larger core nonetheless.

 

That is a modified ebay core, I wont get into the merits of it as some people will insist they are ok. As far as the core size being too short and leaving space, I would rather have a properly sized core over a core that's oversized to fill a space These cars need no longer than 18", at most 20", anything more than that tends to just trade response for little or no gain in power.

I been looking to purchase this kit myself, it seems as though no one has gotten the FD kit to check out the fitment. I was hoping it wouldn't have the fitment issues the FC guys were having. I can clearly see that the radiator neck has been welded to the top unlike the FC kit at least...

 

rotary works and cx racing is the same thing i bought the v mount intercooler from rotary works and it came in a cx racing box.

 

I was thinking about purchasing this kit too, however after all other's opinion, I might as well just have RotaryExtreme customize one for me.

i feel like ive read this from you before...

18/20x__x__ is the ideal size? what are the other dimensions? i was planning to use my greddy fmic core and modify it..

 

Lets take a core that is 3.5 x 12 x 18 that is known flows 620cfm@10psi, conservatively. Your engine will flow approximately 590cfm+/- @ 10psi @ 8500rpm, (about 300whp). As the P/r goes up so will the flow on the core. You have good matched flow and plenty of cooling area especially on v-mount setup. If we take that same core and add length (24") you will now drop flow to 540cfm@10psi. You're already a restriction on flow at 10psi and the major work of the core is done before it reaches those last 6" of core. So... the little pick up in cooling you may see, isn't worth the extra work, weight, plumbing, the engine/turbo has to overcome more often than not. Some applications sure it helps, v-mounted rotaries I'm not seeing it, especially when most of you guys run 20psi or less. Save the weight, pick up response and don't worry if somebody has a bigger core than you.

Interesting, I'm having a v-mount built this winter and will need to figure out what size Garret core to go with. I think my 4" thick ETS was overkill and this time I'm just going to have something made so I'd like to match it to my specific needs.

 

Generally, you're better off with a thicker and taller (more rows) core than a longer one. As Sean alludes to, by the time the air reaches the end of a long core, it's been cooled and all you're getting is pressure drop slowed response.
