I had my stock TB ported today, pick up the car tomorrow. Also having the downpipes heat wrapped. I hear the TB port its good for 10-15 hp...doubt I will be able to tell on the butt dyno but I am taking the car back in 3 weeks to do a methanol setup for 1.3K installed.

The port including un/reinstall was $200.

Hope I can find 510-520rwhp after all is said and done. I will put her up on the dyno to see the gains. Should I expect to see gains only up in higher rpms or through out the band from the TB port?



Victor, where do we go from here? 520 wheel is about 650 hp...need to find 50 more! Its gotta be in the exhaust porting and IC.

Wow, that's a great price E55 baller. Did they fabricate a new plate also? Boy I sure would like to know what porting did alone for rwhp.

I just ordered the rotors from Evosport, that at least should help preserve power loss during acceleration.

SLcharger

Whats a TB ?

I have a lot of experience with methanol engines, so i would appriciate it if you would explain a little more about the system tou intend to install.

stevebez

Its same / similar to the kleeman K4 throttle body (TB) mod.

Rgds Steve.

650 HP already...Wow...

Do you have your primary Cats removed (they are worth another 10 HP), 100Cell rear Cats instaled of stock another 5-7 HP, bigger pipes 70mm front Header to CATSinstead of stock 65mm pipes is another 10 HP...Diff CAM another 15 HP...complete this with Kleemann ECU and you should be very, very close...

$200!!!! WTF

e55 baller, help a brother out. I am having the Kleemann TB installed $3,000 plus $400-$600 for the 4-5hr install. I know they have to remove the SC to complete this modification. Kleemann's kit consist of a modified inlet house and throttle body. They claim this adds up to 30 Hp and 75 Nm (55 lb-ft). No ECU re-flash is needed with this addition.

What am I missing? Is this essentially the same modification that you had completed?

dsc

For the Kleemann TB you have to remove the SC and modify it to fit the new larger TB & add a new Y pipe.

There is one question I have for you e55 baller, did they open a new gasket to 76 mm and grind the opening on the intake the TB is mounted to 76 mm? I may have my TB opened to 76 but you also have to have the gasket and mounting plate opened or the opened TB will have no effect. Was all this done? Just trying to help.

JamE55

Not exactly the same modification but somewhat. Kleemann uses an SL600 TT Bi-Turbo TB which is 80mm good for about 25-30HP. e55 baller only ported up to 76.2mm. Price maybe steep but stick with Kleemann. Just my 2 cents.

blackbenzz

Damn E55baller, you're going all out. Maybe you can make it to our next track rental. By the way, I might be joining the ranks of the E55 people soon (its either that, a modded 996TT, or a HEAVILY modded Supra). If you come to HIN Chantilly this saturday come say hi. Ill have my silver clk in the show. I am on the same show team as Curtis.

Rock

Jam and dcs, thanks for the replies. I knew there was a reason for spending all that extra cash.

Hey Isaac,

I am going through the install of the meth/water injection right now and will be doing some testing with it in the next 2 weeks.

The only place left to go after the TB and water injection is heads and cams. I am working on these 2 areas right now. IMO that's the only way to break the 520rwhp barrier. Next to that, SLR intercoolers are required in order to get more aggressive with the ECU tuning. The alternative to the SLR intercoolers is to possibly get enough of a cooling effect with the water injection so as not to need them at all.

Between the 2 of us testing the water/meth injection we'll see what works and what doesnt..

I'm still pushing for 700hp and I know we can get there..

vrus

Rock,

The 80mm TB is the best way to go (so far) if you want to extract the full potential of the motor and are willing to invest the $3,500. But, for $250 you can port a stock TB to 76mm and get 75% of the gains.

V12TT TB is good for 25rwhp - 30rwhp
Stock ported 76mm is good for 15rwhp - 20rwhp. ( I beleive Vadim got 15rwhp and 18rwtq when he tested it).

It all depends on how far you want to go with your motor. A stock V12 TT TB is $1,200 from the dealer. But, to make it work you need a few gaskets, an adapter plate that mates the V12TT TB to the Supercharger inlet, and an electronic harness that modifies the signals from the ECU to work with the V12TT TB (the reason for the harness is because the butterfly on the V12TT TB opens in the reverse direction so the harness needs to be modified to make it work on our motors).

Hey all,

I am having www.fcct.net in Sterling, VA do the work. They said it was 1 hour install and 2 hours to port. 3 hrs, $200. I am pretty sure the blade was kept the same.

From what I undestand only early '03 models are capable of having the TB ported -- Victor knows more about this but than I do.

If you guys want to speak to the expert who did the work call Wes Skinner at 571-434-7374 (shop), cell 703-220-9494 however I will try to get answers to all of your questions and will consider doing a dyno pre methanol kit.

They want me to get another head to do a port job. Thats $$$ I don't have. They have just built a Nissan 350Z to run a 6.9@215! That car stock went 14.0. I think they are pretty good if you are in the DC Metro area.

Blackbenz,

How was SEMA in Philly last weekend? Got any photos? I wish I could have gone but was on vacation. I would like to get my car sponsored on the team, never done it, seems like it would be fun.

What/where is HIN in Chantilly?

SLcharger

My car was born with the 80mm TB bore. The early cars had 520Hp. stock, and were later reduced. So in some way, it must be possible to get that TB from MB as a sparepart, as a direct bolt on part.

vrus

Wow! Really? This is the first I have heard of this??? Are you saying all 2003 SL55 had the 80mm TB?

Let me just clarify 1 thing just so we are on the same page... The O.D. of our TBs are 80mm.. The I.D. of our TBs are 74mm.

Are you sure the I.D. of the 2003 SL55 is 80mm? If so, is the O.D 85mm and the connecting pipes 85mm???

e55 baller

wow that would be very interesting.

fyi -- we measured stock 2003 E55 ID=73, OD=80.

SLcharger

I am pritty shure that I.D. is 80mm. When my car was mod. by Kleemann, i ordered the stage 4 kit, but when they dismanteled the engine, they discovered, mutch to their own surprice, that the TB was 80mm, so they called me to tell me that i didnt have to pay for that option. I cant say for shure when this TB was canceled/altered by AMG, or if it ever was exported to US, but i know for shure that it is on my engine.

dsc

If that is an 80 mm ID, is the SC the same configuration as an E55 so that no "notching" would need to be done on the E55 SC?. Would it require new air boxes if it has a bigger Y connecting pipe?

vrus

All the points you mentioned below is why I am very skeptical about this.. If it really is an 80mm ID TB then that would mean the Y-pipe and air boxes would have to have 80mm connecting tubes unless there is a reducer on there from the normal air box to the bigger TB???

Also, if the TB is 80mm ID then the supercharger inlet would have to be 80mm in order for it to make any sense... The only way to know for sure is to get a look at a 2003 and physically measure each piece...

SLCharger: Can you take some diameter measurements of the Y-pipe, TB inlet, Y-pipe connecting tubes, and air box openings?

SLcharger

I will try too, but i quite bussy right now, so be patient.

e55 baller

Ok, so here are more details. The stock 74 mm butterfly plate was kept the same. The port was done of the front side of the TB from 73mm to 76.2mm.

EvoSport did a 76mm port front, back, and changed the butterfly plate on the early stock E55 TB. As a result I would probably expect to see half? of the 15 rwhp...

More air will be available at WOT but the restriction will exist exiting the TB. I have a call into Simon at Evo to see what a new plate would cost and a port on the back side.

FlyByNight

Hey, remember in December when I wrote this in the other detailed thread about throttle bodies? That's what I meant... the 80 had been on some 55 cars in the beginning... including some European E55s... then got dropped down to the smaller ones... per Cory at Kleemann...

"At one time, for just a brief moment, they actually CAME on a couple Euro versions of the E55, then they pulled them if favor of the smaller ones. Pretty sure that's what I remember him saying. Basically, they are just different Mercedes part numbers you order... confirm with Kleeman. "

e55 baller

damn, so they detuned our cars....and probably kept it as a trick among other changes for the E63 to get more HP

dsc

Beside the TB did you hear anything about the Y pipe and air boxes? Any info on mounting? GIVE ME MORE INFO, PLEASE!
