You are correct! Glad someone said it besides me lol

here are the innards of the m113 stock manifolds, hardly acceptable for any v8 over 300 horsepower, let alone 493hp from the factory

I know this is an old post but a lot a lot of people don’t understand how truly sad the stock logs are on these cars

Those are similarly as restrictive as the M275 turbo manifolds. On second thought, the turbo manifolds on the M275 may even be smaller but they will flow close to 700 hp and maybe more. I'm guessing the 4 extra manifold runners help with the flow.

Bad for super chargers, just fine for turbo applications.

I have headers on both my AMG's, but wow I really didn't own how bad the factory logs were with the shields off. Thanks for posting.......but wow, they are like something out of the 60's just stainless rather than cast iron. Then beyond the NO engineering side of design the primary tubes are a small 35mm while the stock ports are 40mm. It's like the engine engineers and the packaging guys were at odds with each other. Why would you purposely go pick a header flange that's too small from the get go? Wonder if the 430's were 35mm and the exhaust team just kept on keeping on with the same.

These would help

Did I miss it or what was the ECU tuning solution? Stand alone replacement or just tuned the stock ECU for boost?

Little snippet of the carnage coming….

That's a biiiiiig pulley !!!!

Bigger is always better, isn’t it

SICAMG

Curious as to what boost will be and if you will have the common boost drop at high rpm's.
Is that a 195 lower ?

black06c230

it better be a 195!! He needs to get back strong in the game again!! He will build an awesome car for sure. Craig isn’t this like your 3rd m113k car?

chawkins2001

SICAMG- The lower is bigger than 195mm, and I have a upper too

H- Thanks brutha! I have had 5 m113k’s, only one wild build that you know of in this thread!
