Exhaust manifold design

[RICE RACING]

Just buy a Precsion PT6766SP (ball bearing) Physical Exact same size as a T04Z and a Tial V44.

I have fitted many to cars recently and they make a jizzillion rwhp, much more than you want to make and the boost control is perfect and the waste gates are durable unlike any of the Aust trash you will buy.

PM me if you want to know what exhaust housing size to run.

The BW turbo HYPE is just that, these cunts do not make the power they state, they are unreliable and many people if you could actually buy one! have swapped to the PT6766, two such cases are the RGM R34 and R32 of Mark Berry, I saw these cunts and talked to them at this years world time attack and the cunts gagged over the switch the PT v's BW, on the straights these two cars were totally rapped and made the power!!! the speeds down the straights were gag factor to the max!

Pics I took of the R32 500awkw according to Russ and it looked it around the track!

Another great illustration of the power of these cunts is this car SR20 4cy making 900bhp anyway you cut it!

2700lb car and over 154mph! on track in 400m!!! and its driven with H pattern gearbox on the street, now that is POWER!!!!

Now why would you want a BW turbo that you have to wait months for?????????? and SFA people have actually made power with it.

There is a RX7 on here, only other one in the WORLD that has had proper VBOX testing and it runs a precision PT6765 smaller turbine wheel and he runs 10's @140mph! and does the FASTEST recorded 60mph to 130mph time of anyone ever in a true road car. I personally verified his power off the VBOX with my own formula. Easily do what you want with that turbo. See my FAST RX7 thread for proof. < Road car, road weight, real power. smg944 user name.

Or PT6466.
Sound Performance tested back to back 6466 against 6766 at same boost level (36 psi) on stock 2JZ. 6466 has significantly better spool-up and due to higher efficiency at these exact conditions (boost and flow level) it also produced higher peak power and torque. Both compressors have capability to flow over 90 lbs/min of air, which is enough for over 700 HP even on rotary platform.

BorgWarner EFR serie is very nice on the paper and some people are reporting very good transient response which is expectable thanks to very light rotating assembly, but Precision seems to be few steps forward, at least in aerodynamics of wheels itself.

Then again, Precision doesn't bother with some burst testing or maps at all But they have results like no one

I was going to post that for him but I did not for this reason.

The smaller compressor wheels heat up the air more in the 22psi + range especially when fitted to a rotary engine, thus I recommend the 67mm compressor (lots of experience running these at high boost) so its better for your engine basically, even at lower power levels, remember a wankel still munches a shit load of air! it just does not make the best use of it (IE power generation).

Go the 6766 mate, you will not regret it, absolute **** loads of them on E-Gay, to your door cheap as! will make the power and will be reliable, I witnessed that GTR getting rapped for two days straight, and before that its done allot of work, on just one turbo, no smoke, no snapped shafts, no excuses.

Actually ................ Try a 64mm if you like, I have not been bothered to do it myself, I'd be interested to see what you find when you fit it to a 13B and run 30psi boost like we do on the bigger compressor.

Look at my website and you will see I made ~500rwhp in 1997 on a 58m compressor H Trim Garrett T04! fitted with my water injection system.

These new turbo's are a light year in advance of that old shit I ran back then.

100% I say to you stick to the T04 platform, its the perfect turbo for the street, compact, massive power, BEST POWER BAND, and they just work.
