Exhaust Advice - R32 Gtr - Twins

Heard my name mentioned.

Just get your gases out as fast as you can AFTER they have been used by the turbo charger....YOU DO NOT WANT BACK PRESSURE HERE PERIOD.

Exhaust manifold design is what governs turbine behavior and that is all you want to affect the turbo...After the turbo, gasses do nothing, they are waste and if you don't get rid of them fast enough they will effect the turbo's performance in a NEGATIVE way....NEVER IN A POSITIVE WAY...NEVER.

MY RECOMMENDATION IS:

Speak to an RB workshop that do this for a living and have done all the R&D on multiple setups to know exactly what you need.

More factors then just the manifold govern the turbine 'behaviour' such as turbo design, PSI, engine design, displacement, cams, Volumetric efficiency and off course witchcraft.

But your theory is no backpressure is the best, so have u tested this on a dyno by running back to back with an exhaust and then without dump pipes to run straight of the turbo like u said?

I'd be interested in the results..

If you really want to learn about RB turbo R&D I would ask these guys before you post anymore garbage.

Or these guys

They have have so much knowledge that it would make you head explode. And it's all based on 20 years of real life R&D.

When they talk you listen because 5mins with them teach you more than the years crap that you think you already know.

discoPumpkin - Enough is enough. Just give away the posting on this issue

Thanks.

After speaking to JEM they've told me they i could go a bigger exhaust but the minimal gains are quite pointless on my setup...

For the 1kplus id be spending for not that much of a gain...

I'll be keeping the current exhaust and ill upload a dyno when i'm finished it all.

[Piggaz]

Sounds good mate.

Post a graph after the tune!

Good stuff mate. That's the best way to do it. Everything else healthy?

Yeah man the car is really healthy and im fussy with all my maintenance.

So hopefully she stays healthy haha.

Hoping i can run the 10.99. Ran 11.8 on std turbo n std ecu.

i think its doable but wont be easy.

Awesome mate make sure you post up your time and mph. When are you heading out?

Won't be draging till at least December because november 30th powerplay is on and i've got a garage once again.... Knowing my luck ill break shit before powerplay if i drag hahah.

It will happen though... For now you can check my video of my stock run haha.

Ben, I hope you don't mind me asking on your thread but I want to get advice on my potential exhaust setup:

I have a basically stock RB26 (R33) in my BNR32 with a R32 std mani, turbos, dumps, front pipe, cat, and 2.5" mine's cat-back.

After reading this thread (all bullsheit aside), I'm thinking about upgrading to BNR34 std mani, BNR34 std dumps, 3" Titanium front (short design vs long pipes), ARC Ti 3" de-cat, and Mine's Ti 3" cat back.

My BNR32 is a club racer so Response > WHP. Can I get this ya'll opinion on my setup before I enter my credit numerals into websites?

[KiwiRS4T]

If you have read the thread carefully you will know that you won't lose any response but on a stock motor you will not see any massive increase in power. But it will stand you in good stead when you do go for more power.

Make it atleast 3.5 inch from the merge of the front pipes back. 3 inch is wrx toy junk!

Lol. In my situation, I'm going for weight saving via exhaust, lighter wheels, rotors, etc. I'm not sure if there's a Ti exhaust that's affordable and 3.5".

My theory about the BNR34 manifold is: If the BNR32 dumps are crap and the BNR34 are better then won't the BNR34 manifold be better than the BNR32 manifold...? is it a waste of money to but a BNR34 manifold?
