Awesome!! Now there are 2 of us! Our numbers are growing.. Soon we will overpower them.


Thanks for the kind words!!

I was going to type up a nice response, but, Jrocket summarized it nicely for me.

The car pushes enough boost as it is.. Its just very restrictive and generates way too much heat in stock form.. Why compound the problem by raising the boost another 3psi???

Adding headers first opens up the exhaust path (gained 30rwhp for me on my stock car) and removes some restriction. This drops effective boost by 1 - 1.5psi with evosport headers. Right off the bat less heat (coated headers, plus increased efficiency).

Next, 80mm TB.. more air going out, now we can feed more air.. The whole car responds much better with this mod.

Pulley & ECU last because you only want to program once so get everything you want installed on your car and then have the ECU tuned to take advantage of ALL the mods.

Headers: $3000
80mm: $2400
Phenolics: $289
Cooling kit: only 2 retail packages available RIGHT NOW (more coming SOON) $3,000
ECU + Pulley: approx $2,500

That's a basic overview... Rflow's car is at 531rwhp with a mix of these mods..11.3 in the 1/4.

 

Id say coolin upgrade first...then ecu/pulley then headers and TB's... Good luck

 

I would say ....

1. 80mm TB is a must, what ever you do, and almost undetectable as all parts are AMG.

2. Pulley is a sweet and easy mod .... There is some evidence that the 175mm pulley is too parasitic and while it adds decent boost adds loads of heat. Only go 175mm if you going to add a coolling package. But either way this is best bang for the buck. If I would do it again I might go 170mm.

3. The biggest baddest cooling package you can fit - regardess what you do above. If you going 175mm pulley fit this at the same time, and remember too much cooling is just enough here.

4. Headers - here I am a bit stuck. The Evosport is a great shorty, but has stock diam primaries. I would have liked slightly larger primaries - but maybe I am just annoyed 'coz they wont fit my right hand drive . There are a few log style manifolds masquerading around as headers but mostly all they have going for them is larger diam primaries.. so not all together a bad option with reasonable pricing and some fairly incredible power increase claims. Any other headers involves some chop-chop and unless you going to delete the CATs I would not bother.

5. Airbox ... good power claims - but even if it did nada it looks gr8 and it complements 80mm TB, headers, Pulley VERY nicely. I think a must on a Pully/header/TB car. You also get some decent flow air filters with it.

6. ECU tune ... tricky - custom would be ideal but not many do this ...

7. If you going to track (real track) the car at all then change diff ratio to 2.82 + add Quaife ATB (LSD). The 2.65 gearing is way too long.

8. Brembo GT brake upgrade kit. Again for any track work these will be a must. You will need 19" wheels for the brakes to clear. 245/30 & 275/30 rubber goes well here with no clearance issues - you can go slightly larger but then rim offset gets a little specific and makes gearing a tad longer and lowering a little restricted.

9. Lower car by min. 30mm. either via STAR or after market module. Better handling and more agressive look. With no. 8 above lowering is easy and clearance again is not an issue.

10. Some interior detailing, Alu door pins and chrome seat adjustment buttons, but I digress....

11. Finally , a spare pair of underpants in glove compartment in case your SBC brakes fail...

Think that covers it! Enjoy!

 

I can attest to this one.. It's not fun!!! And I hope no one has to go through it... Good recommendation Steve.. You dont want to wreck that expensive leather...

 

Thanks VRUS for the updates..........So if I understand correctly, The headers and the 80mm TB/Phenolocs could be installed without the cooling kit?

Just want to verify when the NEW IC has to be installed.........

What are the install hours for the Headers? Install hours for the 80MM TB and Phenolics......

I will add roughly $5,700 (cost of headers and TB) to the labor cost of $95/hour to install both mods......

it seems 50/50 split with ecu/pulley or tb/headers... Has there been a recall on the tb? I was told that there was in the past.

I am proabbly going to start with pulley, cooling, headers, tb and then have the ecu programed to work everything correctly. should I have the exhaust replaced and have straight pipes installed?

 

Get the best of all worlds, do all of it at once. Less down time...

 

Hey buddy,

Talk to some of your fellow crew members from SD and they'll point you in the right direction.

As usual, most people miss the obvious, which is better tires. All you're doing with the power upgrades is working your ESP overtime unless you get it to the ground. The cheapest, least intrusive and most reliable mod there is. The cost margin for R compound is modest and perhaps even negative.

 

I can unfortunately attest to this one also...

 

I can unfortunately attest to this one also... jus glad that it was LATE at night and no one was on the freeway...

 

I will try and check out creative and group 5 in SD. I received some good feedback from everyone on this forum. It is obvious that cooling is a big factor in the process of mods for an E55

 

Is there a good R compound tire for our cars that won't get you killed in the rain?

 

Toyo RA1's I had on and no problems. Also, found it very difficult to smoke the tires with these, unlike the Nittos I have now. I would have put RA1s back on but I may be turning the car back in at lease-end and didn't want to have to buy new tires then as well...

 

did you stick with the same size tires or can you go wider? maybe 275s?

 

Do the RA1's come in 19's as well as 18's?

 

275s

 

just for the sake of keeping everything in one thred .

Which out of these two headers would you guys think to be better
evosport or kleeman?

i understand that the kleeman ones need you to do some chop chop.
but whaich of the two is better ?

Thanks

 

Or try brabus like me, mb warranty, 580hp not bad at all. Running now with just over 70,000km no problems at all, I ordered the car new like this

 

wayy to revive a four year old thread...

 

Just figured it could do with reviving as I keep getting asked about these things here in Spain mate
