300E Performance
He is neither skilled, nor experienced at age 16.
I have yokohama AS430 tires, got my brakes changed about 3k miles ago. Anyways i don't plan on hitting over 100 MPH very often. I will spend a while testing the limits on the car handling wise, etc all before i will ever do much above 85 or 90.
If i planned on hitting over 100 very often then i wouldn't be too worried about 0-60 because the 300E would start fighting back at about 60 or 70.
Could i please just have a list of the TOP 5 best performance upgrades for under $1000 or so per upgrade. I might not even get any of them, i am just curious as to what i can get.
And i don't want the parts for top speed but simply for acceleration times.
As i have mentioned before on this thread my car has been VERY well maintained over the years. In Texas we don't drive on salted roads or anything, sometimes i drive it to the beach, but not actually on the beach. After i drive it around the beach i clean it off pretty soon.
It only has about 105k miles on it right now and at just over 101k miles we had a bunch of things done to it. From what i can tell, the car is in excellent condition except for the 1 dent in the back, and a few scratches on the paint.
The 300E is always kept in the garage unless someone is out driving it, so it has seen minimal sunlight, rain, acid rain, etc.
I was just simply asking for a list of the TOP 5 performance upgrades. I wasn't looking for why i shouldn't go over 100 mph or why i am an inexperienced driver etc.
Thanks
You see a car that wants to race you and then from there it kind of just happens on its own. You don't think about what CAN go wrong or what WILL go wrong. If you know what i am saying?
Can a K&N Air Filter (not whole new intake, just the filter) can make your car sound a little bit louder. True..False? Also would a high performance air filter add even maybe +3 HP or so, or not?
Then what about a chip, will it really give around 5-7 hp? Because a $100 chip that adds 5 HP or so is a good deal IMO.
Will a custom exhaust really add 8-10HP?
Could i just PLEASE have a list of the FEW upgrades i can get that will add HP?
What about getting the mesh layer under the headlights, will that make it perform better? Because that is where out Intakes draw the air in from, so i figured it would be able to breathe better.

Did not notice any change in power although the car may be breathing easier as I've noticed it has smoothed up a bit at higher RPMs.
Chip is doubtful to work at all. Exhaust may net you 8-10HP but you'd likely have to remove the cats/precats.

Also what Rear Differential should i get? Does the later 300E have 2.65 or 3.06 rear diff.?
I am probably either going to get the 3.27 or the 3.69. Right now i honestly can't decide which i want at all. The 3.69 is going to give me wayy faster acceleration times than the 3.27 will, BUT im afraid that it would be bad for the car if i go on trips where i am averaging 60-70 MPH. If running the car at 4k REVS for 1 a whole hour isnt bad for the car, then i definately want the 3.69. But if that is horrible for the car then i will just revert to the 3.27.
Also, just wondering, how much will 3.69 rear differential slow the car down top speed wise. I think the stock 300E is a top speed of 140 or so. So how much will the 3.69 rear diff slow the top speed down? I definately won't ever hit over 115 or 120 i am just curious.

That is the seller I purchased mine from. Arrived quickly and was packaged very securely.

Not sure. First of all, you'll never reach 140 as the car is limited to 135 (if I remember correctly).
These cars handle very well, so i would think im in a position to go over 100 MPH when the times are right. Not on an every day bases but every now and again ill push it into the 100s
You're fifteen years old and if you want to drive recklessly then go ahead...
Providing you only kill yourself and the passengers in your car.

If your parents allow you to drive over the speed limit, then it's easy to explain why you are as you are...
Your parents are less responsible then you !!!!
It's the innocent drivers that fools like you usually harm.

Stop encouraging a potential dangerous driver....

The Best of Mercedes & AMG
But anyways lets drop this subject about going over 100 mph. The ONLY REASON i want these performance parts is for faster 0-60 times. I don't know if anyone here has realized it, but 8.4s is pretty slow for 0-60.
And my car does 3k revs @ about 70 MPH. I will probably just get a 3.69 ratio if "taching" 4k revs isnt horrible for the car. I will just make sure my car has plenty of coolant, oil, etc before i go on any long highway/freeway trips.
Then i want a custom exhaust system, another perf upgrade or 2. After that ill probably get 17x7 or 17x7.5" rims, and get 1.5" or 2" lowering springs so its slammed on the ground.

And yes i know that larger rims will decrease 0-60 times, but if i get really low profile tires the rims and tires will be about the same size at the stock ones. As for being .5" wider, that will slow it down but only by about .05 seconds if that.

Anyways, what is that turbocharger..i havnt ever heard of it before. And it claims 485 HP which i know is BS. But could a turbo like that even give 50-70 hp? Or will that thing not even fit on the M104 engine.
My guess is that it is a universal part.
It looks like the turbo comes with a decent amout of parts including new gauges and stuff like that. I just don't know if i can trust a turbo like that selling for $1600.
IS that a trusted turbo? Or have you not even ever heard of that.
THANKS

I'd honestly look for a more efficient turbo or supercharger and keep the boost low.

And how much would 17x7 slow me down 0-60, and what about in the 1/4 mile.
How expensive is it to get the 3.69 rear differential??
PS......Don't be to heavy on the pedal, I learned my lesson right around your age and walked away from a totaled C280, with my life. These sedans tend to feel much more composed at high speeds than they actually are and you forget that you are driving 90+ mph easily in a W124. It's when you need to make a swerve to avoid something in an emergency that you are quickly reminded that you are in a semi-boaty 3500lb vehicle. Be safe above anything else!
So i might do as saijin has said and try to find a more efficient turbo or supercharger that i can run at about 6lbs of boost and still get good performance.
Also he said getting the rear differential would be expensive since it is a mercedes and i would have to take it somewhere to get it tuned afterwards etc.
Does anyone have a rough estimate of what the cost of a 3.69 rear differential is in the end? After any possible modifications must be done to it.
If this is all TOO expensive for an efficient turbo or the 3.69 rear differential swap, then i will just revert to custom exhaust, and a new tire/suspension setup.
Maybe get a K&N filter, mesh under the headlights, you know..any small cheap upgrades that will even make the verrrrry slightest differences.

I would shy away from a turbo setup if this is a daily driver. Get some bilstien HD's, springs, K&N and call it a day. Any kind of HP gains on these cars are very expensive and usually labor intensive.
That would be like the 300E 2.8L going 0-60 in 8.15 rather than 8.4. Can i trust that? Will it make 0-60 that much better?

A.You don't need mods,you need Meds
B.As evidenced by youtube video you need nothing added to make it faster than your little brain can make you shiete your pants.
C.Why not have your daddy buy you a quicker car?
D. That way we can be at the memorial all the faster

Anyways i am not looking to make my car go any faster than it already does. I want it to accelerate quicker. I don't think there is a car out there that the 300E 2.8l can beat off the line (0-10 mph).
And the reason i want some performance upgrades is because the car CAN be quite fast. Imagine if it did 0-60 in 7.2 seconds, thats not that fast, but that will cut the 0-124 time by 2 seconds or so. And 32 seconds 0-124 is pretty damned quick IMO.
Not that i ever plan on going 124, i am just making a point that it starts moving once you make it past 20 or so.
Obviously you have some performance upgrade rivcal4life. Because if your best 1/4 mile is a 13.805 @ 102.94 then you're doing it faster than the stock 500E.
So what upgrades do you have? Or is it only because you probably ran it straight off the headers at the track?
I'm not looking to have a car that accelerates and moves like a ferrari, lambo, or E55 amg etc. I am just looking to improve upon 0-60 by about .6-.8 seconds.
DONT EVEN TELL ME THATS NOT POSSIBLE!
