Hey guys

like the title says


How many of you running 180cp or 77mm sc pulley

with stock fueling ?

no one ...its about 18 psi of boost ... stock fueling is max out at 15 psi i think

yeah sorry ... just use one of them and it will be ok

180 OR 77. Not both.

I ran a 180CP for 6 months on stock fuel. No issues but was always fearful so I went back to stock.

I run stock fueling on a 74 mm fixed s/c pulley and a dyno tune from BIP. Boost on that should be about 14 psi.

I do have an upgraded heat exchanger and split cooling from BIP, and a Bosch 010 pump.

Worth the wait

A 180 should run fine on stock fueling with a proper dyno tune.
Of course if you are running a lot of other mods, or your pump/filter is running slow, that's a different story.

I have been running a 178CP for almost 6 years
I also have shorties and intake mods. OE dyno tune.

I make almost 700whp on 18-19psi and I run stock fuel pumps. I do have Eurocharged 550cc injectors though. And I have NO looped fuel rail either because you don't really need it.

But then again, what do I know?

So it's ok to use the 77mm pulley with stock injectors, also interested to know for sure if this works, looking to make it my next upgrade

sircl55amg

yes its about 12.5 - 13 psi no problem with a tune

How about that plus MBH headers?
And by that I mean injector size
