I've done the crazy 700HP cars in the past and am not looking for that again, however, I am really tempted to get a little extra kick. Maybe 40-60hp

My car has 60k miles, great shape with a EC Heat exchanger, new bosche 010 pump with split cooling and gutted mufflers

I was considering, 2 or 3 options.
1. and 83mm pulley with EC tune
Or
2 Long tube headers
(or 3, both lol)


Would the power increase be about the same (83mm vs LTH)?
My guess would be the pulley would add more and be a little cheaper then LTH, but if they are the same, then wouldnt the headers be better for all around? less heat and stress?

thanks guys

 

Let me just say this because you know it and I know it. You will do all 3 and then some eventually.

I still own a 900whp (Turbo Ws6 Trans Am) and now just bought the E55 for more basic fun without all the work. But I still find myself almost daily looking at all the sites for pulleys, exhaust, etc.

Its only a matter of time my friend.

But do the exhaust first.

Exhaust would have better benefits

 

Your probably right, but I'd like to think I'm more disciplined now then my younger self Lol.

Headers would also sound pretty good

 

I just bought my 03 and the guy before me did the eurocharge headers with no cats and a tune. Thats it. I couldn't believe he stopped there.

It sounds perfect. He left the factory resonator and mufflers.

 

I say either or is fine. If u do mid length headers and 83mm SC pulley and a tune..then u will be very pleased indeed.

 

I would open up the exhaust meaning do the headers and let her breathe a little bit.

My vote is long tubes. Preferably MBH or American Racing. If those are too expensive, then Eurocharged or Kleemann mids. Single best mod you can make to these cars, bar none.

 

You should do headers first, as you will find that an 83mm wont cut it for your power desire, youll end up going with a 76 or smaller in my experience, also the Longtubes with Tune will Net you more power than an 83mm with tune.

Check out our website to see our various >Pulley< and >Exhaust< Options, there are quite a few to choose from

 

How long have you had experience for? lol

 

I'm sure it will make more power, but like I said, I'm not looking for the monster 9sec car. Been there, done that. Just need a little more kick lol.
I've done both, and Not even taking reliability, practicality and cost into factor, I've learned"fun fast" brings more joy than "scary fast"

 

With the money for Long tube header $2K+ why not invest in Mid-header (Kleemann or Eurocharge for $1K) and add the pulley. You will get much more gain than long header alone. I currently have Kleemann header, tune and 84mm pulley. The power and the sound is perfect for me.

 

My 2006 E55 has ONLY an 83mm pulley and a EC tune and it reduced its V-box 60-100mph time by a full 1/2 sec. 5.0 down to 4.5sec. My 500lb lighter, cammed LS7 Ute, 11.8@120 does the same 4.5sec. My 77mm pulleyed, tanked, EC stage 3 and tune, no cats, SL55, does it in 3.9sec. I actually prefer the silent Tesla like thrust of the E55 to the much stronger but very loud SL55.

 

Funny you say this, I made my decision and ended up doing exactly this.
The long tubes will likely make a 10-20 more Hp if we are generous, but you are paying a lot more dollar per HP for those last few ponies.
I got the:
83mm upper clutched pulley
EC with tune
EC mid length headers.

 

Congrats...good call. The 83mm and tune are the best bang for the dollar and you have addressed the basic cooling needs. The headers also make great gains and help the sound/fun factor.

My car has similar with the exception of ARH LongTubes. Thanks for the SC oil...recieved yesterday and plan to tackle soon.

 

Called it

 

Good call you wont be disappointed

 

Do people just round down the wrong way, or this pulley actually 83mm now? Mine is closer to 84mm but I bought it from Shardul a while ago, and not EC.

Not that it matters...just wondering.

 

Haha...5.4L but 55...84mm but 83. Offsetting penalties I guess

 

Ill measures when i get it. i guess it depends if your measuring in the valleys or on the peaks of the v's.

I'll admit its hard to go back to an older platform, feel like im late to the party compared the cts-v or z06 etc. Topics have been discussed to death, but they were discussed over a decade ago and so when you search everything you find just refers to previous threads with out providing much info.

 

Chuck lets run, we have the same set up basically. I have shorties with a 77.

If you can do both get Long tubes/ 77 SC Pulley from Shardul. If you have to choose, long tubes/tune are a healthier route imo.

I have a 77, Shorty headers, tune and make 480/530
My friend has the same set up but Mid Lengths: 77, Mid lengths, tune and makes 510/550.

Long tubes /77 would put you closer to 530/540 WHP im assuming.

Either route you will need to add cooling mods otherwise youll be back to square one after a hard run (HEAT SoAK )

 

I agree. Good older info posted, but a lot of new info and ways to do things that may not have been posted.

 

Hey Josh, just come over and let's run !
Is your 77 with clutch ? Shorty header which brand ? I think I have about the same power as your car. I have never running into problem with heat issue so far. (upgrade the CM30 7 years ago...)
