AMG E Power

I think you will be fine if ur not taking it to the drag strip alot. 750lb ft of torque being put down to the ground from a dig something will eventually break if not upgraded, just my opinion.

The compressor wheels in the turbo E63 M157 are also replaced by bigger and lighter Billet Compressor wheels

This is all you had to say ^. 500lbs is a huge difference.

Previously you were saying the cars weighed the same, one was down 70RWHP and had a passenger and was beating the other car, didn't make sense. I call it how I see it is all.

All your other comments underneath are completely unnecessary after stating the weight difference.

jrcart

Sorry bro, I took your comments as you questioning the stated claims and hp, I was thinking this guy is usually cool and a straight shooter why is he starting, but I can see how my post could have been confusing.

This has been posted by Weistec in the past. They explained that even though the M157 makes so much power on the dyno, the M156 puts it where it really matters. That said , The M156 redlines at 7000-7500 RPM, whereas the M157 redlines between 6000-6300 RPM. Therefore, as the M157 loses potential, the M156 would still be pulling hard. In addition the airflow in the M156 6.2L will allow it to reach a desired value whp quicker than the M157. there is no replacement for displacement


BTW, JRcart, The E63 weighs 4100 lbs. Not much diffrent than your C63 BS. Check out the reviews and the offical AMG website, the E63 is around 4100-4200 lbs

The BS pulls away from the E very easily.

Did not expect that result.

@jcart - what power is the BS putting down now?

Is there a dyno graph available for the E63?

jrcart

My C BS in this video is only putting down 660ish whp, my CLK BS is putting down around 900whp.

The E is no slouch, the only car it lost to all day was my C BS if I am not mistaken. The E is an absolute monster, they just make and put down power differently. 60-130 I feel the Weistec M157 E is quicker than my C BS. We raced a few times and the E alwasy jumped out to an early lead and the C had to play catch up, no competing with the torque the Weistec tuned M157 makes. Pretty sure Aero and weight came into play at the big end as well.

jrcart

The weights i am quoting are real world weights with fuel and drivers. MB says my C BS is 3800 but it weighs over 4100 with me and fuel, trust me I had it on scales.

jrcart: your cars are simply amazing! Congrats on the awesome runs along with the weistec builds! That run on your clk with the gtr is something to be proud of! Regardless of the numbers of horses on any of your AMG's.. They're a mark of engineering respect!

Weistec

The E63 is a heavier car by a few hundred pounds. As Jrcart mentioned, it's the up top where the Stage 3 catches the E. Based on how fast a Stage 3 C63 is (10.50's in the 1/4 mile) we would say our upgraded biturbo E is right where it should be. The Stage 3 Supercharged cars are pretty damn fast as well. Comparing any car to this is saying something good.

jrcart

We just can't win....we post up CLK HP numbers and people say and No Way and now we post C HP numbers and people say and think we are sandbagging lol...damned if we do damned if we don't I guess.

The BMW, SVT and Vette forums are all calling us liers and sangbaggers, they all say the C is putting down between 700-900whp I WISH!!!! i take that as the ultimate compliment though, never hurts to exceed ones expectations.

jrcart

Thank you and I am not ashamed of losing to that GT-R, I am actually suprised and happy just to be in the same camera frame when we crossed the finish line, that is one serious monster of a GT-R. I was not expecting to show up at this event and have the second and third quickest cars, there was some serious muscle at the event, lots of VERY quick cars. Weistec built me a couple of monsters and I am proud to be able to go to these events and represent for all the MB/AMG owners out there. Every car forum on the planet is taling about "AMG's" "Black Series" and "Weistec" this week...and the BMW guys are taking it the hardest LOL, the Mustang guys are actually being pretty cool with the exception of a couple guys. Corvette guys are being cool too.

Point2Point

Great job by you and Weistec in showing the potency of the M156 cars!

I saw how angry some of the BMW guys are getting about this. There's one particular dude that has just exhausted his mental capacity in trying to make arguments against our cars and falls back on threats of physical conflict! Talk about

AKnight55

Congrats to Weistec and Jcart.. You have built some awesome cars together. Way to represent.

emericr

Congrats on all runs. Amazing accomplishment on both cars.
Sad that people being beaten by others start doubting their words.
We are all gearheads after all.

JamE55

M5 board says they love you long time after that video. LOL What would more interesting is how about a tuned M5(F10) vs your WS3.

G55AMG

Jrcart

You have 2 amazing cars, great builds. And you done some great runs.
I have really enjoy watching the videos, very impressive.
And the BMW guys will not be happy for a long time. I thank you for that LOL.

Great job.

vdubpower

who tossed out that allah akbar in the beginning


jrcart - so what is the difference in mods between you c and clk,....out of curiousity?

weistec...post some pics of the E with the diffuser

props to all

jrcart

I will try to get Weistec to chime in becuase I do not want to mis-quote something but off the top of my head I think the following differences should be accurate.

Biggest differenc is boost, CLK BS is making 14-15psi as where C BS is at 10-11psi. The higher PSI CLK requires major fuel system upgrades. The CLk is running Weistec race ported heads, Wiestec forged rods and pistons. The C is running stock internals and stock heads and valve train. The CLK is running a totally custom intake system as where the C BS is running the stock intake with Weistec filters. CLK has heavily modded trans and C trans is basically stock with the exception of some cooling upgrades that I had them add for road course use. The CLK runs a race fuel Weistec tune and the C runs a pump gas tune. Both cars have primary cats deleted. There was about a 200-250 whp difference between the two cars at the event but there were obvious traction issues so the CLK could not lay down all the hp.

Hey jrcart, have you tried a run with the rear wing removed?
Would it be too unstable at 170? Not that you need it but, You would certainly gain a few mph, if stability is not an issue. If its adjustable, I'm sure you've already set it for least downforce.

GeorgeSmooth

is this with a 55mm pulley? I am seeing a bit over 12psi with mine. If I knew how fast the car is with this configuration I might have not gone the full engine build monty.

GeorgeSmooth

I thought about this again and ten minutes later I have changed my mind. Happy I went full monty and cant wait to boost the cars pistons out.

jrcart

You went the correct route, you will have the flexibility to run smaller pulleys and more boost when you want to, not to mention stronger internals should you ever encounter detonation issues. Keep in mind I have two cars with Weistec blowers, the CLK running big boost with the Weistec internals for drag racing, I didnt want to go as extreme on the C BS, the 660whp I am making is just fine. Nowmhurry up and get your running already.

GeorgeSmooth

MMMakes sense. I am running well now on low boost. Gotta do fuel upgrade next weekend and boost to see what the big yahoo is about

Ezec63

Weistec

I see Jrcart is running 11 psi/660 whp on the stock engine and trans. I know you've said the mct is stronger and can take more power than the old 7G. I have a 2012 coupe so I have the mct but no P31 or black series internals ! How much stronger are the p31/bs internals compared to the regular m156 internals? You guys change them either way when going for big power so the black series forged internals obv aren't as strong as your internal upgrades. How much boost/power will I be able to run with the mct but non PP internals?
