Where are your oil coolers located ? excellent fabrication by the way ! I can see that a lot of thought and imagination and work has gone into your system ! It absolutely shows !!!!

im going to have to agree with rotarygod that exhaust manifold looks great. merging before the turbo will work better then merging at the turbo. and yes other people have thought of the Orings before i use them on a regular basis on intake manifolds and restricters :P.

Thats a really nice manifold is that your own 2-1 merge collector pipe?

I suspect that its a generic merge collector as can be purchased through companies such as Burns and such. It has a slight joint that was welded, yielding it a usesless slip joint, I suppose if its already there though, its easier then trying to butt weld it.

My first post here:

I am the guy responsible for the fab work on infinit1 and our road race RX7, driven by Jack Mardikian.

I'm glad you guys like the fab work I have done on these cars, so thanx for the nice comments.
I pour allot of energy into these projects, and most people cant see all the details, so thanx for noticing.

If anyone has any questions about the project, feel free to ask me, I will answer when I can.

and as far as the header /turbo / gate combo goes, this is a proven set-up, that works pretty well on our race car RX7. it is the fastest car in it's class NASA-SU here in Kalli, even faster than our supra..:confused: makes great TQ. and is pretty tough to beat on any Road race track, viper.. porsche..what ever. the RX does not discriminate...

any way just wanted to introduce my self and say Hi.

and some pics of the RX-7 race car are up on our site www.twinsturbo.com in the project car section.

oops, I said slight I ment slip joint D'oh!

really incredible fabrication on these cars, much props to you...

i am a little curious about the setup below:
http://www.twinsturbo.com/project_ca...s/IMG_2025.jpg

What is the function of this bracket and the lines running into it. (i am still kinda new to single setups) i have never seen this before.

It's a vacuum manifold.

very cool, thanks aaron.

looks like a great way to cleanup and manage the vaccum lines

What size downpipe are you running there?

the DP is 4" it transitions to a 5" oval and goes all the way back in 5" oval, transitions again to 5" round and vents to the atmosphere no muffler.

sucker is loud! loudest car we have ever built.

spot on, we have never built an FD before, this was our first attempt, glad you guys seem to like it.

can i get a "goddamn?"

Damn, awesome fab work. I've seen you guys on tv before with your Supra project.

infinit1 - your car is turning out great.

Both the manfiolds look great, I would love to have one. I recently saw the supras in super street, you guys do awsome work.

Hi , and welcome to the club ! Your work is top notch , I wouldn't mind trying something like it when I put together my next manifold ......., It wouldnt be the same , but I really like the LONG runner concept for the rotary ! , how long are they exactly ?

thanx for the compliments.

the runnres are pretty long...so long, that I fear posting the actual numbers,

I dont want start a "that will never work" debate.

How long?

I don't think anyone (including myself) was saying that it wouldn't work, just that it wasn't ideal. It's very rare to see a long runner turbo rotary manifold. Most people keep them short to maintain turbo response. Same with the use of divided housings. Probably not an issue for a car that is designed to operate at high load in the higher gears...

Awesome work so far...do you have a picture at another angle of the wastegate arrangement?

Aaron, dont be offended, I wasnt directing that comment twords you or anyone particular here..I just dont argue on the internet..too many "armchair experts" for my taste.

and we were trying to make TQ with the manafold design, turbo response is not a problem, we data log alot of stuff that helps us determine if the turbo is doing what is expected of it, and adjust accordingly, to suit the drivers needs...ETC.

Nice. I wonder how their twin turbo set up would look for the FD's.

those things have got to be close to the 3' mark - give or take. i'm rather intrigued. oh, and it really doesn't matter what you do, someone is still going to question, disagree or just flat-out try to discredit/undermine it -even if it's just to be a dick. so don't let that stop you from sharing anything you wish. let your craft or unfinished research stop you, but never one of the crabs that sometimes lurk around here. i think you'll find out quickly who the open-minded and/or scholars are - and they will always respect you, even if they have a different opinion.

if all else fails, i'm still a believer ...

Its a new "out of the box" approach that hasn't been widely tried yet ! so I doubt anyone can honestly say what it will do . On a side note , I saw a turbo kit on TV for a V8 that locates the turbo at the back of the car next to the gas tank ! the dyno sheet showed boost response very early in the range , somwhere around 2000 rpm !

Looks very nice...what kind of torque are you guys getting out of it? I would be interested in something like this if in fact it does improve the torque significantly

http://i15.tinypic.com/4ypftar.jpg

all most 400 LBS @ 5300
and 500 HP @ 8500 RPM

at 19 PSI, and it does this all day long, on a race track, sometimes but not often, it is inches from someones bumper, and it stays cool.

keeping this thing cool during a door to door race, has been challenging.

again this is the first RX7 that we have ever built, so I guess that makes me pretty FAR out of the box..
:)

Nice! But you need to load your company bitmap image there. ;)
