Question...?

Is this (1131410125) part number for a 80mm or 82mm throttle body?

Hammer Down

Not sure but 2731410325 is the part number for the MB 82mm

Ok thanks....

Hammer Down is that 82mm plug and play.

Hammer Down

Yes it's the part number for the 82mm from the 550 engines

hammer down, would you happen to know a ball park estimate of how much does a 550 V8 throttle body with welded adapter on the stock snout cost with whatever else needed?

74mm throttle body is really small for a 5.4L V8 Kompressor. I think a 82mm and tune should add a nice amount of power. Without touching the boost level. Would you agree?

Hammer Down

Hey Max what's up stranger? I cringed when you said welded tb plate. You can pick up a snout and have it bored to 82mm and then extra material added to so that you can relocate the mounting holes. I paid $300 to have my snout bored and extra material added and about $325 for a brand new snout but unless you have MB hook up I would suggest buying a used 550 tb for around $400 or so. You can get a brand new GT3 82mm $300 but you have to switch two of the pins due to the blade opening in the opposite direction (any competent MB tech can do it) if you choose not to.

Ohh sorry buddy that's my mistake. I think you need to weld the plate for 90mm throttle body. So, if I pickup a 550 throttle body I can bore out and weld my stock snout. Obviously would need a tune right?

Hammer Down

Correct on boring of your stock snout and on the retune. Since you would have to take the SC off go ahead and add phenolic spacers and a heat shield in the valley between your block and SC intercooler. DEI makes a heat shield

carguyshu

you also need the y pipe that goes from the 2 air cleaners into the TB from an 07 or 08 SL.

HeissRod

This is the first I've heard of the DEI heat shield. Link?

Also, I thought I had read on here that phenolic spacers were about as effective as an intake Tornado. Something about the air moving too quickly to absorb much heat.

Hammer Down

It's actually from Jegs. I only bought one to put in the valley and I wish I'd bought two.

Anybody know the part# for the sc inlet to fit the Mb 82mm TB

you can use a 80mm inlet with a flange to bolt on a 82mm TB.

Right way is to modify a stock inlet without the use of a flange to mate it to a 82mm TB

ghlainez

Thanks Shardul, now I just need to find the y pipe to fit the 82mm tb

youre saying its better to bore out the 74mm stock inlet vs starting with the 80/82mm blower inlet? Can you explain why? Thank you. All this time, I have been looking for a larger s/c inlet to do this mod...

m3j0n

also, if the TB is for any other model 550 other than the E, lets say an s550 for example, are there any differences? P/n is the same so I figured its identical, just wanted to ask. Thank you.

Hulk

You need to find a 82mm Benz tb, try the S550, for the snout you can port the stock plenum and after weld a plate to attach to the 82mm tb

OR

You can get the 80mm plenum and add screw holes to mate the 82mm without any adapter plate, it's a cleaner install.

just bought a 82mm TB Should have it by Tues. Now where can I find an 80mm plenum? and have a partnumber/application for that? should the 80mmm plenum be bored out to mate to the 82mm TB?

Hulk

Yes the 80mm plenum should be ported, I don't have that part number any more

m3j0n

do you remember what cars they came on?

cost. unless you would like to say 400 plus for the 80 snout and what ever the flanges go for these days.
with the flange the y pipe and air boxes are post back toward the firewall by the thickness of the flange which sometimes will result in air boxes not being fastened to the original mounting points on the valve coves

Hulk, if you just port the stock pletnum why would you need a spacer?

Hulk

You will need to weld a plate to attach the 82mm tb
