First, I'd like to say congrats to my friend E55W for joining the 500whp club. Also, OE tuning for doing a grate job on tuning the car and TTM for providing the best fueling solution to keep our motor happy!

We took this virgin E55 down to DRT in Queens and got some impressive numbers. Our first pull was kind of disappointing at 469Whp but after scratching our heads, we figured that the dyno fan was not in a good spot. We made our adjustments to the fan, let the car sit for about 15 minutes then dyno again and the results was 513whp with 605tq.




Our final numbers was 518whp but we didn't get a torque reading so we left it at that for the day. The car was getting stronger but we called it a day and plan for our next list of mods.





List of Mods

ASP 185MM pulley
TTM injector and rail
OE tuning
Cat & Resonator delete
Meziere pump

Wow those numbers are high for a car without long/mid-length tubes, maybe a little too high. Im sure the car feels hella fast from that 185 but those numbers seem suspect.

Johncy2000

Nice numbers man!

BenzoBoi

Very good numbers for the mods...

As I started making my way down the post, I was expecting at least headers besides the posted mods...

KLR CLS

Nice to see numbers like that, but I would take it with a grain of salt. No way the car made more than 600WTQ through stock manifolds. What was the net increase?

_AMG_

Those are some very strong numbers!

CLKCLK

I make sure I move the fan around and bring an extra fan next time I dyno to get that 40+whp jk. Very nice number

Black_55AMG

What should the numbers be with a 185 pulley ?

Black_55AMG

Thanks, now all we gotta do is get MBH to do a group buy.

Black_55AMG

From you statement i guess you're impressed...

Black_55AMG

Thanks and yes stock manifold, net increase from what?

btw...the first pull was without cool down coming off the streets...it does have the stock heat exchanger....

Black_55AMG

It's a good start, we expect more with headers,tb and custom OE tune.
I cant wait to see the outcome.

im curious what air charge temp these cars start pulling timing out. cooler the aircharge the more power

GregMB

MBH did a group buy last month!




Impressive numbers.

Your car loses about 80whp in the upper rpms...not good. I'm shocked it even touched the 500whp with stock manifolds.

E55W

I was very impressed with the results , with that list of mods

Hammer Down

Was this a OE "box" tune or OE custom tune by Jeremy?

skratch77

your dyno has a wacked correction factor.1.17 in the middle of winter? it was 37-40 d out that day and the air pressure was 29.65

You sheet says the air pressure is 26.01 and temp as 74? was it that hot in the room and did they dyno with the doors closed?

Ask the shop for uncorrected numbers to see how it did without multipling by 1.17 I would be at 620whp with your correction factor.

GT-ER

You are right. Usually in winter in the US the correction factor would be under 1 ( .96 for example ).

The barometric pressure is low...I smell fish.

skratch77

I think his first numbers of 469 were right and then the air pressure was changed after.

No way a fan can make that much of a difference,heck even dynoing from 90d days to 40 d days only made about 15-20whp max difference for me

chawkins2001

HOLY High numbers Batman!

Couple things from that graph, firstly it makes great peak power, but as mentioned above, that is all it is. The power does not hold through the upper rpm range which makes sense for your mods, the 185MM gets it up there quickly, but due to your lack of cooling mods, small throttle body, stock manifolds, and big crank pulley, the motor gets heat soaked extremely quickly.

Once that happens, it pulls timing fast, and you see a major drop in HP in the upper rpms.
Dont get me wrong, those are great numbers, but peak numbers mean nothing on the street, you want it under the rpm range and to carry out to redline. That graph is a nice graph for bragging rights on the dyno.

E55W

And also the dyno only had one small fan

Black_55AMG

I did not SET the correction factor multiplyer to 1.17, it's based off condition inside the dyno room. C'mon scratch get hip to the program already. SAE (Society of Automotive Engineers) correction factor, otherwise known as "corrected numbers" is an established baseline, to help increase the accuracy of the numbers a person sees, no matter what dyno they are on. So No I'm looking for uncorrected dyno figures. With SAE I can take two cars for example; anywhere in the world at any time and compare their SAE corrected numbers as though they were being tested in that same room, at the same time under the same conditions.

Black_55AMG

You're always wrong and make the dumbest comments.

Do some research about big pulleys, air temp, and E55 with limited cooling. you've been on this forum long enough...to learn something

Ok wait let me help you....

If this car can make 469whp with stock crank pulley, upgrade supercharger pulley, cooling, cat delete on dyno which appears to be a lower reading dyno that a dynojet. why can't we make 518whp with 185MM pulley and TTM fuel setup which has been proven to make 20+whp alone?

the baro pressure that they used is WRONG and usually they hook up the software that pulls that info of the weather station.

that is the lowest baro ever and close to the lowest ever recorded on earth.Enless your dyno was done in the middle of the pacific near the equator with a typhoon about to start lol

I know how the sae system works and have dynod my car more than I can remember and I already looked up your pressure and it was 29.xx not 26

We live in the same area of the country and I put my car on the dyno and SAE actually LOWERED my numbers because of our great conditions now to make if even with the people in hot weather areas.

Going from memory it was 68 deg in the dyno room and about 45 outside and the baro was 29.xx and sae used .97 to lower my numbers.

Im not saying your car is not making good power Im just questioning the CF and baro used.
