I didn't take those conditions into consideration...how careless of me

Stock
130 16 sec
150 23 sec
So 3.5 sec / 10 mph
It will increase above 150
At least 33 sec to 175

then how am I hitting 220-230km before I hit the top of this hill? I start from around where this photo is taken. it doesn't take 30 seconds to go up...it's like a 500 meter hill...I'm sure i can hit 250+ on that hill if I start far enough back but theres a gnarly turn at the top

jrcart

I'm not sure, but if these numbers are true I will give you $100K cash for your car today. Show me a video synced to a V-Box and I will wire you the funds this afternoon. Download Harry's lap Timer App and send make a run and post up the video

avery.whss

maybe being right at sea level helps? i'll take a video in the next few days of a run on that hill

Ingenieur

Big difference between 140 mph in 500 meter ( looks more like 200-300) and 175 in less than 15 sec

And you aren't hitting 140 in that distance
Looks less than 1/4 mile (400 m ) and up hill
Nope

Ingenieur

Maybe 10000' below sea level
That would add 50% hp if fueling could keep up

jrcart

All he needs to do is download the $19.00 Harry Lap Timer App and go out and make some runs and post up the video. Best App in the world, might put V-Box out of business lol

avery.whss

i'll download it this weekend, is it for android? or ios only?

jrcart

It's available on both. There are a few versions, pony up the $19.00 for the top of the line version. You will also want to buy yourself a suction mount for the windsheild to hold your phone.

I'll have to check it out
I have dynolicious and it has quelled more than a few bench racing arguements
What i find amusing is the lack of understanding of what it actually takes to go 0-175 in 15 sec!
That is no mean feat

avery.whss

im uploading a video right now i have from when my car was stock..going down a slight hill, i'm doing 30km-ish to 165-170km-ish in around 7-8 seconds ..so 0-175 in 15 is totally do-able..these are KM i'm talking..are you guys talking MPH?

Ingenieur

It will be a somber reality check

Ingenieur

20 to 105 mph in 8 sec
Easy
Stock is about that
That I can buy

And yes 0-175 mph in 15 sec is doable
But not in your car
Jrcart's yes, yours, nope

0-175 km per hour?
In 15 sec???
You were saying mph (if kph makes no sense since that is 4 sec slower than stock)
A stock car will do 175 kph (108 mph ) in 11 sec

avery.whss

yeah then why is a tune with straight pipes 0-250 <20 seconds so hard to believe then? I'm hitting 170km in 7-8 seconds..with a tune i'm hitting that in probably 6-7 ..that still leaves me 10+ seconds to add another 80km-110km..not that hard if you just have the pedal floored

theres guys in calgary with mods on their c63 that get walked by 300whp evos...they probably do 0-100mph in 7-8 seconds

Ingenieur

Your post
0-280 kph or 0-175 mph
In < 15 sec

I use this App, in conjunction with VBOX Sport. Its great!

avery.whss

11 seconds to 170km stock? you sure? I'm hitting that quite a bit sooner..although it is on a slight hill..i doubt it makes that huge of a difference

starts @ 1:33 ..

car is bone stock in that video..even was having issues with CEL it was choking sometimes in 3rd

Ingenieur

No one said 0-150 mph in 20 sec on a heavily modded car is not believable
Only that 0-175 mph in < 15 sec is not believable

'Flooring' it doesn't matter
Hp/torque does
You not hitting 105 mph in < 8 sec

It takes much longer to go from 105 to 175 mph than 0-60 mph
> 20 sec vs 4 sec

Ingenieur

Most tests have 0-100 imph n the 10 sec range maybe a bit less
105 will be more
Grade matters a lot
5% grade 3 deg is a 5% hp advantage
Yes it matters...a lot

AMG893

Look,
The only way to end this, is go on FLAT ROAD, with VBOX + Video, and do it.

I appreciate that vid you put up, but you were on a downhill gradient (even slightly, makes all the difference, as does the negative in a slight uphill)

The rate of speed the vehicle gathers (our types anyway), slows down after a certain point.

175Mph = 283.5Kph.

Audi R8 V10 Plus. Does it in approx 22 Seconds.

F10 M5 Approx 26 Seconds

Benz E63 AMG-S 4 Matic- Approx 27 Seconds

NO WAY C63 is beating ANY of these with Tune & Headers

sure can, these are probably stock doing 0-250km in 20 seconds...another 30km would add another 2-5 seconds...not bad honestly. No way do those c63s have headers in those videos..they sound stock,

AMG893

+ in your vid, your not at a dead start. Its a rolling start.

C63 2012 Coupe with PP- 31 Seconds Approx

Summary
Stock
0-120 13 sec
0-150 23 sec
120-150 10 sec
So 150 - 175 at least 8 sec
But since accel tapers off a lot > 150 closer to 12 sec
So a stck car will take AT LEADT 35 sec to jit 175 mph

A tuned (software, filters, decat, headers) will not do it < 15 sec
Lol
