Would having custom made bigger surge tank make any performance gains?

AMGPilot

Nope

StarvingArtist

You can connect the two though.

V8Displacement

I don’t think connection will make performance upgrade

SICAMG

I had mine ported pretty good and did not notice anything.

AMGPilot

another waste of time and effort. it won't do anything.

If it did don't you think that MB and AMG with infinity deeper pockets would have?

SICAMG

V8...just add a little more boost if you are looking for some extra power, or a tune. Cheap and easy.

Wonder why they didnt put LSDs in from the factory, or better cooling systems, or more boost, or bigger throttle bodies, or what about that god awful exhaust manifold. But mercedes doesnt ever do anything we could do better ;-)

SICAMG

Those manifolds where the best !!

i am surprised that no one has come up with some way to isolate the intake valves in surge tank via new runners -- having the exhaust valve opening and closing has to have an effect on boost - probably to expensive to design/machine - am i wrong with my understanding of how the surge tank setup works

V8Displacement

But most people use smaller pulley than Mercedes design for more more power

V8Displacement

Is their any other way we get more power or increase the capacity of that super charger other pulley change

drothgeb

Why try to reinvent the wheel? What's your goal? You just really dont want to spin the SC faster?

V8Displacement

I already did and want more

drothgeb

Oh gotchya, hows your cooling? What temps do you see on hard pulls?

V8Displacement

I did the usual cooling mods pumps , heat exchangers
didn’t do any measurements for IAT

C32owner

So if you done cooling and pulleys already I guess you have done the exhaust and custom tune as well? Sorry on mobile and can't see your mods list if you have it there. Also what pulleys are you running? Maybe you have room to go more aggressive

drothgeb

Get some sort of data set up before anything else. If your temps are getting high better cooling can get you a lot of power.

V8Displacement

I did the usual things and looking for something out of the box

drothgeb

The usual things minus any sort of monitoring?

Makes even more sense to have it before you start pursuing out of the box ideas
