what power can wagner manifolds take you to

[Jamo]

OK, good to know that. I always thought it was just a difference in inlet diameter. I have a GT3071R in my car, so what would you like me to measure? The outside diameter of the cold-side?

Yeh i'll measure my 3076 and post the details up. I didn't measure it last time just did a visual on the two.

I'll do it in cm not inches

It's the coldsides that differentiate the turbos in the GT30R range.
The GT3071R has a compressor A/R of 0.50, the GT3076R has an A/R of 0.60, and the GT3082R has an A/R of 0.70. It's easy to see the difference.

ok, that clarifies it

Just to highlight, tried ct367 on an evo manifold, and sits there without mods or spacers. That is a nice 800hp turbo, if You wish to push to the limits.

Only need to choose gts turbine housing to avoid grinding of the turbine inlet.

Evo em turbo side outlet is garrett BB specific, and practically all other T3 flanged turbos in the world follow the old style, which is a couple of millimeters smaller on each side, and a bit more round. Bolt pattern, nevertheless, is still the same, so even if You had old skool turbine, grinding is a three minute operation with a good die grinder.

here is a Dyno Sheet of a Customer Car with

EVO Manifold with 3K Flange and Oldschool K26/27/29 Turbo
Short IM with RS2 IC

not to Bad for these Components...

Hello, what power can I reach with Wagner exhaust manifold, original but new K24/7200 turbo and RS2 Evo Intercooler?
Thanks a lot!
Bye

[A80Avant]

i would assume it all depends on what map you have. It is not a matter of what hp you make on a cold day in a dyno, but what you can make on a daily basis. EVO intercooler and EM will help in that direction but the EM being larger diameter than the original EM might bring a tiny bit more lag.

id guess around 380-390 is possible if you dont want to worry about rod bending

All depends on the map not the manifold, the Rs2 turbo won't even scratch the limit of the Evo IC and Evo IC.

At 2 bar the RS2 turbo can hit 400 bhp

Ok, so do you think that a Evo Intercooler and a Evo exhaust manifold are oversized for the K24/7200 turbo? Can the reverse intake manifold reduce the turbo lag and the power loss that have the original intake manifold because the air after pass on the intercooler pass on the exhaust manifold and so arrived in the engine that is not really fresh?
Thanks a lot!

my advice would be start with the exhaust manifold to keep egt down and stick with the stock inlet.

keep the air velocitiers high withy smaller tubes and inlet.

there aint much time to heat up the air through the piping as it goes. it travels further thats all.

The reverse Im is a must mod if you have the money, the throttle response and drop in lag is day and night

[GazzaG60]

even on a small turbo? id like to see some comparisions. we know it is higher. way back when i installed mine i saw 500rpm on my sc6152e.

cant see it on that small snail.

Even on a small turbo, ask s2_Bo or Sonic, they did it on a K24 and could not believe the difference.

Do remember you are removing 1.5 m of pipework and the air temp will be lower.

Any car will benefit from the reverse IM.

[Audi-Porsche Avant RS2]

Ok Jamo, so also with the K24/7200 turbo the intercooler kit and the reverse inlet manifold is a good upgrade.

Thanks a lot!

Yes it is!

That's what I'm running on my car. It does the job quite nicely..

Even before the RS2 setup went on, using a larger IC and the reverse inlet it raised boost threshold by .2bar with generic MRC chips compared to the stock 3b IC and normal inlet track.
