Manual Vs Auto Mph

[Pazzo]

12.53 stock? Fark not a bad effort.

[aussie1926]

I got 12.95 with stock suspension, and down to the 53 with coilovers

[#96]

I found I was only slightly lifting between gears (noticed a spike on the tacho) and certainly didn't hear the BOV like you would on the road.

13.2@108 all stock manual.

Fwiw, the stock BOV seems to vent quite slowly (ie its not a TSCHT! more of a Tsssssssschaa) and I'd imagine this helps retain intake pressures off throttle. Reducing lag on gear changes.

Had a side by side pass with an auto, and every change saw him creep forwards about 2-3M.

Very interesting. I went 118mph with 330kw with a 6 speed manual. What mph does a 310odd kw auto get ?

slightly old thread, but dynos readings vs mph is very inconsistant.

in my BF2 manual with 295rwkw, street tryes, I did 12.9 @ 118mph, 2.2 60ft (bogged down)

as a stocker with 205rwkw same dyno, street tyres, I did 13.4 @ 105mph, 2.0 60ft (almost perfect launch)

118mph seems high for 295rwkw, but dynos arnt gospel...

285rwkW in my old car equated to 102mph.

[discostig]

That's below stock mph?

[k31th]

BA mk2 F6 typhoon... I'll re-check the figure... 110.34mph 285rwkW

Edit: it was 102mph when I missed a gear hahaha

More like it!

I ran up 317rwkw on XFT's Dyno Dynamics brand dyno in 2010. I trapped at a highest of 121mph, with 120mph on my 11.9 PB. Raced a month or so after it was tuned.

The same tune years later was 322rwkw on the Mainline they now use.

Since every dyno is going to read somewhat differently and how the car makes power with different ambient temps is going to give variations in power compared to trap speed. The way both cars are tuned would create variations - the power curve also has to be considered too not just the peak power reading as your always putting down different amounts of power from standstill to finish not just one figure.

I'd say if you had 2 cars that were 100% Identical in rear wheel power and the way they make their power across the rev range, the Auto will be quicker by a bit as you would lose some acceleration on the manual when your shifting gears.
