I'm upgrading my pulley to an 84mm for more boost. Looking on Ebay i found two different ones. So which one is best? 84mm in the black or silver pulley?

FLINTY55

Silver is a clutched pulley and black is not. Stick with clutched 84 and get a tune for it.

I was new to all this once too. All of us were. You sound VERY green. My advice is to spend some hours reading this forum and elsewhere to familiarize yourself with these cars and their capabilities before you start modifying them.

I agree with wide ride, do a bit of research on here and you'll figure it all out. Most likely you want to start with an 84mm clutched unit. As a tech my advice is before you do anything and depending on the mileage and condition of your car, make sure all the maintenance is all done, plugs, etc.. You might also want to pay close attention to the fuel pump age and the filter/ sending unit. Take your time!

I would stick with the clutched pulley. They can be found in almost any size

Ruthle55

I would research way more. No offense, but you don't even understand how a pulley system works. The last thing you should be worrying about is modding the car.

The car is immaculate with maintenance all up to date. With only 19,000 original miles. Cheers

If I were you, I would enjoy the car in stock form first, and bring the maintenance items up to spec.

Do you research as there are so many mods out there, and you really want to add them in a specific order.

Just the answer i was looking for

Thank you

Hazeyboy94

Yeah if i had time to spend researching i would. Unfortunately i don't, hence my question to get a quick answer. I've already talked with Shardul and told him what i use my car for and he recommended the 84mm pulley upgrade and a tune and that's all i'll do. I was just unsure which pulley to get, the clutched or unclutched. Thanks.

I can understand not having the time. I would suggest looking at this message board daily and reading up. Even 10 mins before you go to bed you will learn a lot. if you get bit by the mod/speed bug you will make the time.

get clutched ... and smaller than 84mm ... the smaller the better

Ls1toAMG

If I had to do it over again, these pulleys where not made then, I would go 78 mm cluched.

Why? It does not max out the injectors and it's equal to a 178. Sure the 77/180 make a few more hp around 8 your AIT go up to a level you become slower without a tank and injectors.

Invest in a great set of headers. MBH or ARH. Add the 84mm blower pulley to that combo and you'll have a beast.

This. I would do long tubes before anything else. It really wakes up the E55. Almost like a different car

nanayaw6

+1 on the headers. Just for some perspective, my last dyno with headers and stock pulleys had me at ~504whp in 50f ambient temps. Headers really wake these up. Open her up (headers), cool her down (heat exchanger, meth/killerchiller), then add boost back with a pulley/pulleys of your choice. my $.02

DVC

Great numbers brother! Which headers are you running?

FLINTY55

What nanaywa6 said... I did Eurocharged mids and a tune. No dyno stats but the car is running very good and I lost a pound of boost in the process. That's a good thing! Stock manifolds a terribly restrictive.

kponti

77mm clutched pulley for the win!!! With ecu/tcu tune

FLINTY55

Personally and respectfully, after seeing the stock manifold restriction, I wouldn't put a 77mm on without headers. Not saying it won't work but lots of backpressure with stock exhaust system.

nanayaw6

I am running the old school eurocharged long tube headers from several years ago with some minor personal tweaks .

DVC

Nice!

Add you to the list of 99L, 2000UJZ, and I all making right at 500whp with stock pulleys and long tubes (MBH, ARH, EC LT).

dchl21

if money is an issue you can get kleemann headers ...its under 1k and very nice ... I fk **** up with it.
