Yup, Bruce told me 5th gear. I should have asked before though and I would have done all in 5th. Live and learn. Im happy I did at least 1 5th pull and the power was the same as 4th but the torque was higher.

4th is not a "wrong" gear to dyno in, it's just different. I've seen many dynos in 4th, then 5th...pretty much the same, cars with headers and without, back to back runs. I think a 4th gear pull relates better to the track anyway. You may be 1:1 in 5th, but you still have the final drive ratio.

I got my c63 also tuned by OE-tuning. Damn pulls like a ****. I had the charcoals removed-CEL. So I put them back no more CEL. Anyway screw the dyno. I ran my friends 10 E63 tuned from 40-140 I beat him by 4cars-we couldnt really tell gap was too big. Stock for stock-even. Jeremy is the man!

A bump for the OP and Jeremy.

Here's a thread that might interest people here in the Bay Area https://mbworld.org/forums/w211-amg/...gathering.html.

Sick!

bassn_07

Thanks Eugene!

The last time out to the track I vboxed a few runs and I was consistently running 8.40's. Not the fastest but given that the temps were around 91 degrees when we started and by 9:30 pm they dropped to about 80...not too bad. The vbox had me trapping right around 128 mph so I was a little off my times due to the weather. When the cooler weather hits I'll definitely get some much better times, but for now it's 8.40.

How's your car running?

Jeremy at OE Tuning FTW!!!!

James@ACG

4th gear is used when doing a baseline to tuned graph as you will not be able to get a full pull done in 5th gear without hitting the factory speed governor. 5th gear is the best gear for the 63 AMG's however if your trying to do a apples to apples comparison you'd have to do it in 4th gear when comparing to a stock run. but the great thing about this is propain has a 5th gear pull now, so from this point forward he is going to be able to get a apples to apples comparison with any other mods he does from this point forward as 5th gear results can be used.

Congrats! impressive numbers. I'm thinking about getting a tune soon.

I have done 5th gear stock Dyno and 4th and 4th gear was always lower for me. Btw my car stock stoped 5900 rpm in 5th gear so I do understand what u saying

mthis

This is my 4th gear pull the 364 is the baseline the other WAS my PC tune.


This is 5th

Any suggestions on how to cut the airbox? How much of the flat part should I remove basically?

Jons95c36amg

Dont touch the airbox-doesnt do jack.

propain

Wow.. that was obviously a bad tune. You got an MHP tune since then right? No numbers since then? Who cares, your running an 11.5!

propain

You have any data to backup that statement? Before and after numbers?

I don't either, but im not making any statements like this about it. Just curious.

mthis

yeap

Jons95c36amg

Let me tell you what my car did today with just a tune-airbox not touched. I met the guy with the 440 stroker motor-Jr 666 yeah he wanted to run you he told me. Well the run was very close. But way up top I started to pull. He yelled at me after that This guy runs low 11s. But his brick like aerodynamics slowed him.

After I posted that I read on here I think from Superlubricity that if your car is stock and has the speed limiter then 4th gear is the gear to use. But if you have the speed limiter removed, then 5th gear is the one to use.

I baseline dynod my car, which is stock, in 4th gear. So, I guess it's good to know that my car actually has more hp than it made on the 4th gear pulls.

BerBer63

My car made more in 4th than 5th gear on a DJ so I don't think that's absolute.

EUGENE-Taiwan

those are some awesome times.

my car had a rebulilt of the engine. with sleeves lowered compression the works basically.

I'm waiting for a new fuel system now.

should received it by this friday. and after that I'm hopping on the dyno to get my car tuned by OEtuing

and we should be seeing my car going 650whp+ on Gintani's dyno

but there is a learning curve for me to lear now the drive that thing after

I can't wait!!! I have a AAM P800 GTR waiting for me.. its going to be fun

SonnyakaPig

My bad. I thought 5th would make more. But I guess sometimes it doesn't work that way.

SonnyakaPig

I bet your car is going to be so much fun to drive. Enjoy all that power.

What kind of fuel system are you going to be getting?

propain

4th and 5th made the same power for me. The torque however was higher in 5th. More load.. more power.

TTMotorsports

If we have a client that wants the CORRECT gear used for his stock dyno pulls all we do is raise the speed limiter so we can do a proper 1:1 dyno pull.

Can't you just raise the limiter with SDS like we do James? I guess that explains your above post and excuse, I mean explanation.

Seems like using the proper gear in pre and post dyno pulls is the only true way to properly dyno and get your apples to apples IMHO!

Even Money

Why 1:1? I know that's what everyone says, but have yet to see a good explanation.

Seems to me that you should use a gear that mimics driving on the strip/track, offers enough of a load on the motor, and gives you enough data points. I would think that running in 5th would exacerbate the lack of air on the top end.
