Take it to the track to back up those #'s!

Here's a video of my car on cold start.

whats the actual rwhp/tp with 18% drivetrain loss/sae.

Jason Anthony

that's what's being measured.... rwhp. 497hp to rear wheels.

Ppl can post their pretty Dyno sheets all day long.

Track numbers don't lie.

i'm sorry but your mods do not make that power, more like 450-475 rwhp at best on a DJ...

Jason Anthony

Do you understand how to read?

GHAZAN

SAE #s?

... and what makes you such an authority? Can you please post your backup including means and medians for all cars on DJ's with the exact same mods in the exact same atmospheric conditions and the same dyno settings? I've seen C63's on this forum with just a tune and rear cats removed make close to 450whp (not sure if DJ).

To the OP,

You list some stuff but you don't list a tune on your list. Is your car tuned at all?

Jason Anthony

It says OETuning in my sig.

Yes....it's tuned.

Hi Jason

Jason Anthony

Do you have headers? Are you catless? Row airboxes? H-pipe?

mr747

I have 200 airbox s afe air filters 200 cell cats and same tune

Jason Anthony

So not same tune. My tune is Stage 2. We have a completely different set up.

I will have my c63 on a dyno again soon, i only make 310rwkw lol with tune + headers + filters. With a different tune and different dyno where i made 330rwkw i was .2sec and 2mph slower!!! dynos r just dynos for tuning.

mr747

I agree bud

Jason Anthony

Nobody knows kw guy. You've basically posted on an English written post in gibberish.

aussie e55

hey jason cool down & act like an adult even a child knows to google just type in kw = hp not that hard. why not try the 1/4 mile strip & prove your point & put an end to these back & forth emails all the best.

mr747

It is the same tune bud I don't want to argue

As aussie said u should go to the track and prove those number if u run over 121 mph I will believe u

mr747

Either way ur car sounds great congrats

I'm curious as to why it matters so much to everyone?

It's on a dynojet, so the numbers will be affected by what gear he runs the pull in, as well as the fact that his choice of wheels / tires are lighter than stock, etc. Heck, a different diameter / overall circumference wheel will affect the results of an inertial dyne.

If he pulls a 497 rwhp on a steady-state dyno vs everyone else pulling 450 rwhp with the same mods, then you can complain that something is wildly wrong (either with his testing or with your mods....).

Any numbers you get from a dynojet are pretty much meaningless except to compare peak output from the same car, on the same day.
