Turbo manifold design

[RICE RACING]

Fuck that is a nice looking turbo!

[RICE RACING]

This turbo like the sierra sierra cunts run would be nice to use, it looks good too. > read more here > http://www.importtuner.com/features/...x/viewall.html

EFR 9180 ~900bhp @ 2.4 bar boost pressure

The long to short runner thing is a classic and it WILL do your head in LOL.

One of the classic examples of a horse cock manifold is to look up the old TWINS TURBO converted Red Time Attack FD3S, running massive horse cock exhaust manifold with BW turbo and PENI GROW on steroids 5" dump pipe! and 4" exhaust !!!! you can actually see video of it doing ~480rwhp on the interwebz on a dynapack machine when set to ~20psi boost pressure. The amount of fab work and shit on that engine bay set up is homo in the extreme for very little return in performance.

You can see at least two other examples of short manifold cars running same or less boost and dyno'd on the exact same dyno types returning more power and with the same power band if not actually better. All around 500rwhubhp @ 1.3 bar boost pressure.

Rice I have talked to you before about a t3t4 or t4 .I'm gonna stay with the t4 like you advised ,you also gave me some good info on how to get the turbo to spool faster ,my WG goes to atmosphere now ,if i run the WG outlet into the exhaust will it create better mid range for my street port ? Because it is fucking loud.

[RICE RACING]

100% you will get better mid range with it plumbed back in.
if you copy any of the good set ups pictured here (lol mine maybe hahah) then its not going to cost you "that much" top end HP honestly.

if you look at the majority of 900bhp 2lt to 2.4lt 4cyl split pulse tuned turbine housing race cars (honestly fuck all difference to these and a 2 rotor in operation), be they Toyota, Ford, LOL Chev ECOTEC! they all have the WG plumbed back in and have minimal losses for power 3" to 3.5" turbine outlet exhausts is more than ample for up to 1100bhp output as shown by many OEM race teams too.

I do have some great pics across all these platforms should get around to scanning some and posting them up.

Ya don't think i will be putting pics on my walls , but i do appreciate the good advice . Like I have said in the past I'm not a turbo guy (this is my first and not my last ),I'm a vintage rotary guy and the shop i work at only tunes spec rotary race cars ,so my info comes from books ,theory and as little forum talk as possible.(when pertaining to my car).

[speedjunkie]

The only thing I was ever concerned with as far as routing WG back into the exhaust was that it was MUCH quieter than not plumbing it HAHA. I didn't realize there was a science to that as well lol. I kinda regret that I won't be doing it still with this setup, because I'm trying to get quieter, but it's kind of a PITA with my current setup trying to line the WG up to both flanges and get them tightened down. I can only imagine the mess from TWO wastegates.

Thanks! I can't wait to get home and molest it haha.

Yeah it's the same kind of turbo, just much smaller than theirs lol. I checked out that car quite a bit when I was deciding if I should get it or not.

Alright, I'm definitely doing as short of runners as possible then. I was searching for a pic of the HKS manifold you're using and I came across the pic attached. I'm shooting for something similar to that I think, but with a WG flange off each runner. Now my concern is whether the oil will drain out being that low, since it probably won't be directly above the oil drain on the engine anyway. I have to find a way around this.

I like their talk of turbo speed, not many cunts measure this, its how pro's talk and do things

I am near the end of my turbo's range running it at around 118,000rpm (comp map only goes to 120,000rpm) but fuck it I'll push it a bit beyond LOL, all these things are under rated for safety LOL I rekon you can run the poofter to 140,000rpm not a problem.
