^ this for sure especially on constantly discovering a new weakest link... been there and done that in the audi 1.8T pushing insane boost levels and breaking everything in the process... went different route in the audi b5 s4 and went tial 605s turbos with moderate boost for them (26psi ish) and ran close to 500awhp with no constant breaking crap... know some guys that are running GT kits on the s4's pushing 700-800awhp but they are on the audi forum everyday with a new problem and constantly breaking half shafts... at that point it sucks to own a 700+ whp car that cant reliably handle it... and even if you do fix every weak link, when you finally get it on the road its like you can only touch the gas for a second before you are "go directly to jail" speeds

Anyone test that blower? Any vids? Would be good to see how it sounds and what boost it can put out.

Ali_E55

that blower is for the older E55 W210. not for W211 E55K.

i think e55K can bee reached to 800hp like the SLR. but cooling cooling cooling is the key here. and larger injectors with >82 TB. and every other mod; cams, intake, etc.

e500slr

I agree, cooling is the key but like it was said before, companies don't care about this engine. There's just not much money to be made. So there's custom, which is expensive and usually can't match the R&D of a big company with funding a facility to work with. Credit is given that some people have come up with their own DIY cooling solutions but what we need is a company produced product with warranty that has been tested to work and is efficient and light. It's not that big of a problem if a reputable company does it. Evosport? Renntech? Kleeman? Come on guys

brad @ evosport

Sorry, late to the thread. But what cooling are you looking for? We have a pretty comprehensive 55 program.

thanks
Brad

Worth the wait

A real fix...not band aids.

More efficient intercoolers!

chiromikey

umm...that aren't $6k a pop!

e500slr

What they said ^^^^^

We need dedicated tuning, you haven't really paid attention to the 55k. People are prepared to pay for REAL solutions if you make them, but hey if you dislike Benjamins then that's ok, I'll hang on to mine

BenzoDoc

You mean like headers, pulleys, IC pump/ h/e / phenolic spacer package, lightweight rotors, bigger TB, exhaust?

Not enough, have you seen the SLR coolers? Their size?

gaspam

i believe that link is heat exchanger, not intercooler... i/c is under the s/c

GT-ER

Sorry, but my previous Pontiac Grand Prix had an aftermarket that would make the E55's wither and die. And it's a freaking Grand Prix...lol.

gaspam

thats because it was mass produced and so many of them .. not as many e55 amgs and most of the people that bought them are not really into tuning so we get a small batch or tuners availible...

honda civics have the biggest tuner market and theres a reason... its one of the most massed produced vehicles and dirt cheap so theres millions of kids willing to modify the crap out of them and if they blow the motor big deal, they got car for $1500

really, the cheaper and more accessible the car is to the general public, the more tuner market there will be... this is why there isnt a big Bugatti tuner market

GT-ER

My point was, there may be a billion Grand Prix's....but how many grand prix owners actually race them, and worse, mod them. As an example, I know of 3 E55 here in PR that have been moded. Yet, with the exception of my previous Grand Prix which I turbocharged, I have no knowledge of a single grand prix here in PR that has actually been moded. They are all junkers...lol.

gaspam

well your prob right for sure about grand prix in PR as its more if a redneck car, but i bet if you go to alabama, kentucky or similar southern state then you would see some grand prixs with giant blowers sticken out the hood with rebel flag on the roof made to look like dukes of hazard with posi-trac on the rear and drag slicks pulling up to light and lookiing over and saying "gitter done"

no kidding i see that kiinda crap plenty of times traveling through the south... and same thing for camaros, mustangs, firebirds and transams

gaspam

like this lol

GT-ER

LOL....they are FWD BTW and there are Quicker grand prix's then there are E55's...that's just sick.

gaspam

yeah its def annoying when someone in a hunk of junk can dust a 90K car but economically it makes sense... i mean you take a $1500 car and apply $20K in mods and you can easily have a sub 9 sec car but then again its still junkie...

i wish we could get these cars under 9 sec but that would take same thing it takes for all the evo guys and audi guys... stipped out interior, no dash no air, 15inch rims, chunky tires, 30+ psi boost, race fuel and some more...

but then my womens wouldnt want to ride in my car anymore without all the fancy stuff that weighs it down

e500slr

Stripped out interior? Sub 9s? I know we want to modify our cars to be fast but this is a Mercedes, it's blasphemy to strip it's interior and turn it into a redneck dragster. What's the point too, I mean why not just get a Corvette or Supra? This car wasn't ment for that, I'm pretty sure you didn't buy your car to strip it. I think we can safely say the interior and comfort are a GOOD thing.

If you really wants a street driven 4 door monster you need to spend alot of money on weight savings

1. Lightweight Battery
2. Lightweight Wheels (HRE claim they're working on a Dymag style wheel)
3. KW Coilovers (with the towers and the pumps and everything from AirMatic DUMPED)
4. Carbon Fiber Driveshaft
5. Carbon Ceramic Brakes (not sure if the car would accept Brembo Carbon Ceramics)
6. Bucket Seats (AMG or Status seats) (or HPF M3 seats 6 lb per seat!!)
7. Tools and Spare Removal
8. Full Titanium Exhaust (not sure if there is, might have to be custom)
9. Full Dry Carbon Body (roof, hood, trunk, bumpers, guards, side skirts) (custom job)
10. Replace Lug nuts and other bolt and nuts with Ti ones
11. Custom CF bumper support beams and radiator bracket (crazy I know)
12. You can look for other small ways which are too much to list, listed the big ones

Approximate Weight Saving 440-550 lb (Pano more towards 550 lb if you replace it with dry carbon)

This is all hypothetical though, only a guide to the extremes you can go to and still have a full interior with only bucket seats as a mod. It would cost time and money and is not feasible unless you LOVE your car. Pretty sure the dealer with also not be happy with pretty much replacing 50% of the car, you would also need a place for all the custom bodywork and the Titanium Exhaust. If you do though you would have a car with lower weight than an M5, C63, M3, RS6, RS4, Murcielago, GT-R etc etc.

Point is if your engine is putting out 600 wheel, which some here are, your car will be mid 10s to low 10s with radials EASY, power like that with the weight savings like those can't go wrong, it's Physics!! Plus it would still be a 4 door 5 seater and full interior and soundproofing. Not sure about the Brembo Carbon Ceramics but even with Evosport rotors you'd be looking at massive rotating and unsprung weight reduction. Unsprung weight is the coilovers, brakes, wheels and the rotating would be the CF driveshaft, lightweight wheels and brakes. It would dramatically change the car's handling, braking and acceleration. Maybe some carbon sway bars and bracings could be done for the handling to make the car stiff.

All in all this would be out of love or boredom and definitely WAY too much money so it is HYPOTHETICAL so don't burn me about how its not worth it

gaspam

my point was "IF" you want to get into the 9s like other 4 door cars have done, then you need to do pretty drastic and ugly things to the car.... which i dont... hell i dont even want to do that with my almost 12yr old audi s4 that i got for $6000

but that highlights why there is such a huge mod market for honda civic and not mercedes, bugatti, lambo, ferrari , etc... the owners of these cars are not willing to go to the extremes as civic owners and for good reason - we have way nicer cars

Havoc

I think they are refering to our future mod.

e500slr

I'm guessing they like money and more customers which they would get more of if they did find a solution, if not I'm sure someone else will find it and no stacks for them

e500slr

Havoc I had a look at your VRP 5.7 build, impressive stuff! Did you get any problems with reliability and did you actually dyno the car? Plus how is the cooling, you mentioned "SLR type cooling" in the project page. Also why did VRP get banned from the forum? Also one more thing did your RPM limit change? Did the engine redline become lower or did the engine take more time to rev up due to the larger piston and displacement size?

Havoc

I had a lot of internal issues and it's been a long road. Last problem was valve float and a valve hit a piston. Currently it's all apart. RPM limit was the same and it reved slightly faster. This time I'm going with Ti rods, different pistons with valve relief and increased compression to 9.5:1, and stronger valve springs. We will also increase the RPMs if needed. We never got the TMCs to work properly so we are going with a whole new design.

e500slr

I guess maybe you should have tried the cooling solution with the unmodified car to see just how much it made a difference. But seriously in your opinion is the whole 5.7 displacement increase necessary? Plus did you ever get to video or dyno it? You were going for 1000hp?!! .....and people give me beef for even speaking of 650whp. I love your initiative and dedication though, separates the enthusiasts from the lazy accountants (no offense accountants). You also said 50k on the project was spent To be honest I think the stock block and and displacement with the mods you did like the crank and the forged pistons and like you said, Ti rods. Beef up the internals to the point where you know you have a bit of safety and work with it. You sent the engine back to Canada a couple of times, I bet that cost some $$ right?
