hi, i just picked up my C32 and have been interested in the Evosport components for quite a while. from what i've read, it seems their Pulleys/ECU is a good combo.

how is the longevity of the C32 with these performance modifications, i have 27k miles now, but may not get around to installing them until around 35k(+ ) miles. is it still healthy and will the C32 still last long, because this is my daily driver (i will be driving about 10, maybe 11 thousand miles a year). also, should i look into the aftercooler upgrade for longevity? to my knowledge, the overdrive pulleys come with the intercooler resorvoir upgrade, is that correct?

i'll probably get an eisenmann race 83mm round too.

a question, how much will the Evosport pullies and ECU cost, and how much can i expect to pay total with installation? i have been browsing the boards a bit before i picked up my C32 and have observed that Evosport and Vadim have had quite some success with their C32 components - i assume Evosport is the best route to go. how does the Evosport setup compare to the RENNtech setup, with realizing that the RENNtech will be paying a lot for name. is its performance actually worth the money?

oh yeah, and is the SL55 intake hard to get or install? can i just get it from my dealer without an Sl55 VIN, or do i need to get an SL55 VIN? i have read it is $420, i'm not exactly a DIY guy and don't want to mess anything up so is it still a good mod for the money - it does not affect longevity realy does it? how about the E55 throttle body?

lastly, sorry for the long message - which of these parts will void my warranty. if it is voided, will it just be the engine warranty, or will COMAND still be covered, because i have heard several issues with COMAND. also which mods would you guys do in successive order, as i don't have too much $$ right now? pullies and ecu should probably done about the same time, i suppose.

sorry for the long message. thanks, i'd appreciate any help and info or opinions you guys have.

 

btw, what kind of figures can i realistically expect from 91 pump gas if i got Evosport Pullies and IC resorvoir, Evosport Powerchip, and Eisenmann Race (does it make a differnece :p )?

also, if i added the Sl55 intake and E55 throttle body, how much RWHP and RWTQ can i expect? how about with race gas, say 100 octane?

thanks!

 

Not to hijack this thread but its along the same lines....My C32 will arrive in about a week and has less than 10K miles on it and about 2.5 years of warranty left. Which mods, if any are the least obtrusive and least likely to be a red flag on visits to the dealer for service? I know that super light wheels will be fine. I'm just thinking I don't want to risk my warranty to pick up 20-30 HP with an intake, ECU chip and exhaust if they'll spot items like those and cancel the coverage.

go through stage 1 (pulleys, ic reservoir/software $2890) and stage II (pulleys, stage II software, igntion wires, plugs, headers $5490) vadim has 45,000 miles on his--no problems

i have about 1500 miles, no problems~

with just the stage I, my dyno came out to be 340rwhp and 330ft-lbs of torque. that is with the chip and pulley alone. i have not had a chance to dyno my stage II yet, but i will post result as soon as i get on the dyno.

i have my car serviced at a local dealership for service A. the guys doesn't even know i have modded my engine except for my exhaust system. and... i did alota of research before i did my upgrade... renntech only runs on 93 octane... which is useless in Cali... unless you want to add octane booster everytime you fill up.
the mods will NOT void your warrenty unless they can prove that the failure is caused by the modification.

any further questions?

I have a motto, dont play the mod game if you cant afford to pay the price. You have to be ready to have your drivetrain warranty denied. Lets say you blow the supercharger, bust the tranny, or even worse blow the engine. There is a very high chance that MB will inspect your car for mods. If they see any mods such as an aftermarket pulley, or modified ECU, I bet you my car that they will find any way to void the warranty and you will be facing a repair bill in the thousands.

Most likely you would not have problems with the minor mods, but its a risk you have to know and be willing take to play the mod game. I don't care how much someone tells you the mods are safe, because in the end if you screw something up, they wont be there to pay the bills.

 

Yep - this is all VERY true! No doubt!

Coupe of points though:

1. The ECU is invisible to the dealer - they cannot tell it was flashed.

2. You simply have to trust in the parts that you buy. You are right that you are somewhat on your own. As such, you don't want to be the first one with the mods and you want to be sure that the company that is selling you the parts has really tested them to make sure they will not blow your motor.

Thanks

So what kind of gains would exhaust and ECU mod give?

Kevin

 

Upgrading the ECU without pulleys is good for a little over 10whp (regardless of which software it is). We recommend not doing the ECU without pulleys, as the software we have designed for our pulleys will add 20hp on top of the 30hp the pulleys add.

Modifying the exhaust (cat-back) does not do much for hp; at least not in a positive direction... We found through testing that removing the rear muffler completely only yields 1hp. Removing the resonator was not helpful, until combined with headers.

Thanks,

Ben

 

Ben: Will there be a quad exhaust for the c32 from Evosport?
Or any aftermarket exhaust for that matter?

 

Is there an exhaust option for the C32 that doesn't sacrifice HP/ TQ or audible joy that would save 20+ lbs. in weight off of the car?

Kevin

 

Yes - exhaust is a go!

We have headers now. The H-Pipe (with or without cats) will be ready soon, and the Supersprint mufflers for the C32 specific will be here in Jan. We will also do a quad if we can get at least 10 people interested.

Here is a pic of one of the 2 tips from SS:



Thanks

Brad

 

How much are we looking at for a cat back quad setup? I know you cant give a specific number, but are we in the high hundreds? low 1000's?

I would like it if we could do the cat back, then add the headers at a later time if wanted. One last opinon, Id like something like the stock C32 tips, more oval than the pictured SS tips. Please keep us updated.

 

Count me in as well.

I really want a quad exhaust. But I don't want to loose any power.

Would your solution be any different than the ones that silva and the others did. Is it basically just a bypass and then cutting out the bumper. That is great for the looks but I really want something like what one of the new clk55 guys got done at amg. It looks like a quad through and through from where it originates.

The only problem is I am in boston but I would ship my car if it was really worth it. In my opinion this car would look simply awesome with 4 amg oval tips perhaps a little staggered like the sl55.

 

thanks guys for all the replies and help. guess where my money's going towards next

Accomplice8 - no hijack taken. i think about the exhaust/ecu, it would be best to have pullies as well since the ecu is tuned for the pullies.

SilvaC32 - your car is AWESOME. i love it, and your engine must be very powerful. i admire your C32. was the stage I dyno on pump gas, if so, where are you located (i.e. in Cali, weak 91 oct). thanks for your firsthand insight, so you think its worthwhile mods :p so no problems yet, how does it idle and is it as streetable/is it like stock when you're not on the throttle? thanks again, please keep us posted with your mod progression, very nice car.

s4iscool - i share your concern, that is my main fear of engine mods since the Merc is stock supercharged at near 1bar, which is quite a bit IMO. that's the only thing that's holding me back from whipping out the cash right now, i want to see when people have more miles on the mods, how reliable the car is. that's why i'm thinking of the aftercooler options, as seen on the Evosport C32 at SEMA. i see your point very clearly.

otoupalik - thanks for your insight. can the dealer tell the car has aftermarket pullies? also, how much would the Evosport aftercooler options help for reliability? yes, i am waiting a bit to see how the mods hold up after more miles, because this will be my daily driver. thanks.

mach430 - thanks for the info. do you know if a catback system would in any way hurt performance figures. i had a uuc system u on my m3, and i lost some low-end torque. also, have you heard the eisenmann race on the C32, if so how does it sound? how does it compare to supersprint's new (upcoming) system? does RBTech or MKB make one yet? thanks.

btw, is evosport going to make an intake? if so, i would be more interested in their intake than the SL55 most likely. any other C32 performance parts coming out, power wise? thank you!

 

I think the costs of a quad would skyrocket if it was done as a straigh dual from the headers. It is going to be cheaper to do if you use the bypass method, albeit a bit more refined manner (heat shields, exhaust hangers, h pipes etc.) In the end, Im honestly looking for cosmetic gains and any HP increase is a bonus.

 

Brad,

How about a header, resonator, muffler package?

Jason

 

my car idles like stock...drives like stock. nothin different, but just that i have more power~

thanks for your comments~
