SPEEDRIVEN | E55 Twin-turbo PKG (feeler)
i was trying to illustrate how silly, expensive and difficult the other options are, doing such a huge project on an E500 -- they may as well go all the way and throw a v12 TT into the mix of options---
but-- it would probably be cheaper to just sell the E500 and buy an E55 then Mod it.
My mistake was responding to the dreamer who posted the thought '2 posts' --- I should have known better

As for deisels...they use all kinds of boost. Turbo, supercharger...and in some cases both. Boost is good for diesel because the its threshold for detonation is much higher. ThTs why you can run 80psi on a stock diesel. Not even sure why we're talking about that but ok.
As far as build costs to forge the motor and add twins...its not gonna be cheap. I've got over $15k in my heads and block on my 350z. Spent another 15k on twins and supporting mods. Add a stand alone ems ($4k), a baller clutch ($2700) good to 1400 ft/lbs andin the wnd, you spend alot more than the car is worth. Just depends how much you love your car and how hard a time you want selling it. I have ovdr $50k in parts in a $34k car. Why didnt I buy a gtr? They weren't out yet.
On a side note..rear mount turbos are kinda blah. Pushing air to the back and then to the front again. I'd put em right next to the bell housing or sqeeze them in where your manifolds are now.if theres no room, a engine mount spacer kit would help make room on both sides.
Turbos > superchargers. Tuneable, more efficient, no paracitic loss, and sound better than a sc whine.

If I don't get any bites in the next few weeks, I might head out there just to see. Curious myself. Should be in the low 11s on street tires with the current power level. 800whp should put her in the low 10s high 9s. I sold my drag radials though, so I seriously doubt 9's can be done on street tires...especially with my suspension and alignment setup for road racing. negative 1 degree of camber in the front and 2.5 in the rear. Not really ideal for drag.
Anyhow, back on topic...next car is gonna be an E55, so I'm curious to see these twin kits. I want to keep the oem supercharger on the E in addition to the twins. Compound boost ftw.
Upgrade the cooling system (you'll have to anyway) and you won't have any heat issues. I have a picture somewhere I took on the road in traffic in the Z. 106 degrees on the outside thermo...and the Z's temp gauge stayed low.

I have not posted dynos on my current EV12 set up but the power results are astonishing to say the least. I will round, my set up is putting roughly 700rwhp at roughly 1.2 Bar...thats nothing, what makes it more interesting is the Air fuel is just in the 9.5, 9.6 range at WOT. Thats ridiculous rich. We are not even talking race gas yet, timing etc... The damn boost controller didnt let me raise the boost to 1.6-1.7 bar but I finally got it to that and threw in a new file. Just when we were about to redyno the intercoolers started leaking. we are fixing that right now and will jump right back in the dyno this weekend.
I went with this set up because I owned a 65 modded to the teeth. Everything I ran it killed at the track. While many will say its not practical having this set up, It is the best thing I could have made.
A V12 in the lighter boddy E class is my perfect recipe for a 9 second slip.
While I dont believe in bench racing and definitely dont want to run my mouth without first having this thing go on a track I will not rest until it runs 9s. Its the only reason I went this route. If you do the simple math you will see it will.
If someone has the patience, money and a good shop its definitely doable. The toughtest part is not the fabrication, its dealing with the smallest details in tuning, programming etc. Knock on wood the last gremlin I am going thru is tuning and speedriven just sent me a new file.
I am making it to MIR Oct 7th I hope to make her track debut that day.

also the tranny in e500 and e55 are not the same... e55 uses Speedshift 5-speed automatic transmission which has a torque capacity of 796 lb-ft while the e500 7G-Tronic which is limited to 542 lb-ft..
good luck with that custom 15psi turbo set up on stock naturally aspirated motor
