We are not discussing about full bolton here. Full bolton c63 traps 123+mph. 335i full bolton is not touching that. Anyway back to topic. We did 6 runs the last few he started to fade away right then he backed off 130 I wouldve got him few cars if he didnt back off. Mine is bonestock with the charcoal filters lol.

Here you go making **** up again. At no point were you ever pulling hard on me and you were nowhere close to getting me by a "few" cars. Sure, if I bumped my governor at 155MPH yes you would win since yours is at 175. That's hardly a win.

I suppose if you want to play that game, the first two runs if we kept going I would have had YOU by a few cars if you want to play make-believe or what-ifs.

It's amazing how a report of virtually equal runs now turns in your favor.

Yeah that youtube video the c63 didnt even have headers lol. Other little mods there doesnt do jack. Basically a tune. Put headers on that c63 the 335 is going to lose

If you guys do this, get it on vid and upload it somewhere. It should be pretty obvious who's telling the truth and who's "embellishing" after that.

Say what? Mods listed for the E63 at the beginning of the video:
- MHP ECU/TCU tune
- no secondary cats
- no resonater
- MHP 180F thermostat
- BMC filters

Umm, according to MHP, who produce the ECU used in the car in the youtube video, they "re-tune" the de-tuned 6.3L motor, and it picks up a substantial amount of hp; they claim that:
This is a pretty substantial claimed gain, and I'd like to see independent verification for that level of gain (didn't think they were detuning these things by that much), but if it's accurate, picking up 60-65 rwhp is "jack" in most people's book, and I do know in any event that they're picking up several mph in trap w/these mods, indicating a not-insubstantial gain in hp in any case. And that's excluding whatever they'd get by removing the resonator & secondary cats.

If that c63 had headers it becomes a different animal really opens it up. Somewhere in the 30whp. I was looking into renntech tune and airbox. My c63 would be trapping 120+ easily

I did not have meth on my 335 but I did on my WRX. I am willing to bet that bog you are now getting has something to do with your car running the same ign timing as it was without meth. If that is the case, you are likely losing power as soon as the meth starts to flow. I had to adv the timing 2-3 degrees when I was using meth (50/50 mix), I would talk about the fuel trim too but the WRX was not DI.

Jons95c36amg

From what Ben(135i) was explaining about meth. It makes whole alot of difference because there is no heatsoak. Meaning car doesnt cut timing. Put it this way if he turned off meth his car wouldve got a beating.

I'm sure headers will help (though not sure they'd help to the tune of 30 rwhp = 37 crank ), but my point was that your point that the mods on the C63 in the vid didn't "do jack" is off the mark, at least going by MHP's claimed HP increases.

Anyway, from what I've seen the C63s' non-nitrous max traps (at least in a very quick scan of dragtimes.com) are equivalent to the 135/335i max traps with it, fwiw....if this is the case, then a non-nitrous modded-to-the-hilt C63 should pull a non-nitrous modded-to-the-hilt 135/335i.

all8up

Yeah I know understand the benefits of meth. I had a stand alone ECU before and the tuning solutions (thus far) for the N54 are far from adequate IMO. Since they are piggy backs, the manner in which things are controlled are by manipulation.

So if I use your example and noting the car is not properly tuned....if the car sees a drop in temperature, it should add fuel, and if timing remains constant you will not likely see any more power.

How do you fit a family in c63?

I could put your 63 in the back seat of my S55

on the other hand, I could almost fit my 55 in the back of the Maybach I saw yesterday.

Jons95c36amg

You would be surprised how much room the C63 has. I put 2 bicycles in the trunk with the rear seats folded down. Also had 6'5,6'2,6'3 guys in the car thats about 600lbs extra. They said it pulls like a **** Well I did feel the extra lbs!

Jons95c36amg

A typical tune in the c63 gains 30-40whp. Add headers thats another 30whp. So total roughly thats 60-70whp meaning it increases 5-6mph 1/4. Add it all up thats 121+mph. Mhp claims 60whp just tune is hard to believe.

When I said jack about the little mods-cat delete,resontr delete thats maybe like 15whp the most.

Improviz

Impossible to believe with most cars, but since Benz uses the SW to detune the motor by a large amount, it still gives the car a big boost, more like what a turbo car would get and far more than a "normal" NA car(i.e., one in which the maker hasn't taken a high-horse motor and detuned it by 40-ish hp) is gonna get with a tune.

Well, that's a total of around 50 rwhp, which should have it trapping in the upper teens, so for that Bimmer to hang with it means it's a pretty fast Bimmer in my book. Point is, those things are impressive and very impressive in the bang-for-the-buck category.

i_am_amused

no disrespect meant, but I know exactly how big a C63 is, and it's small.

I know it "pulls like a ****" (even worth 600 extra pounds of cargo), and it's a hoot to stomp on the gas

Deuuuce

That is very impressive. I can do that with my SRT-8 and never would have thought a C-class was capable.

Jons95c36amg

The older C-class is smaller.

Jons95c36amg

Well the S-class has much bigger leg room thats for sure.

This is my race vs the 335i... http://www.youtube.com/watch?v=emZb4B3K9Qc

They are very fast cars and great engines for sure but these HIGHLY modded ones all have problems holding all that boost. Bogging is common in almost every modded 3.0 twin turbo 35. But when they are holding and not bogging those dam things are moving .

E55AMGGG04

LET ME KNOW WHEN YOU GUYS GO OUT FOR SOME RUNS. I CAN GRAB THE DIGITAL AND COME ALONG FOR SOME SIDE BY SIDE COMPARISONS.

Jons95c36amg

Is your E55 stock?

Jons95c36amg

Lol that 335i got a beating. I dont think that 335i had meth kit.

lauer87

Actually, some 335's are in those trap speeds.

lol, I got my 135i for 35.6k brand new, considering I got it that fast with less than 1000 bucks in mods, I have no complaints. Final thing on my mod list needs to be a FMIC, but no rush. I don't do 6 runs back to back to back normally... usually it'd be a long pull, a cooldown period, another long pull, that's normal right? No problems equaling or beating 60k+ cars.

btw, that 335i is fully bolted on in the E55/335i youtube video, and looks like he's suffering the same notorious JB3 6MT bog. I have heard from many fellow 6MT meth users the Procede resolves that issue, so I managed to get one for far less than market value and will try it out.

I am also going to a dyno day this coming Saturday with Jon so that we can get figures on our cars. We will definitely post our results here!

I also will have an 11 second 335i possibly coming down to dyno as well, so we will see.

Brisk335

Yea i was in the 335i recorded in the passenger seat, he was BOgging REALLY hard, so much you can see its like he hit a wall and the E55 jumped out and in front and he was never able to catch. I could have beat this 335i in my tune only 335i for sure that night..

He was on pump gas, almost full bolt on, no meth..
