Yeah, see pic...lol

Well the only place to safely test this out is really bonnevile or the Texas mile. I'm sure with the right sponsors and team this could be achieved. Road kill guys hit 217mph in a 1200hp camero so i guess that mark is phucking hard to get.

day 1 of owning my Z i hit the limiter.

tuned and limiter removed hit 170+ couldnt get a exact read at that speed while watching the road.

car feels solid at high speeds. 120 feels like 70.

sadly the one day doing a pull at around 150 the ducati i was playing with just walked away from me lol

Id be curious to see how accurate this thing is I made. Most of you have probably already seen it. All the data you really need is on the first sheet and you can scale the hp curve with cell B10 or change it to mirror your dyno graph. Its just simple physics applied to our car. You can change the air density and CD of the car as well as the frontal area to see how it affects the acceleration of the car.

A stock car shows about ~170mph. You can scale up the hp as needed to see what it takes to clear 200mph. 420hp to the wheels would eventually reach 200mph in gear 6 with a FD of 3.357.

Yeah but what did it take for the GTR to get to 200? Didn't it take 1000hp or was that to get it to 200 on the track (that long straight in Japan)?

phunk · 09-09-2014, 02:18 PM

I have raced to 175ish a few times, but my comfort zone for full throttle speeds on the stock engine is in the 150s.

I feel like the power I am making is already stress enough on the connecting rods and pistons. Adding in all the accelerative resistance from aero and gearing, I fear that somewhere in there I might be approaching the point where bending the rods becomes easier work than quickly accelerating the crankshaft. I dont usually stay in the throttle heavy in 6th gear for very long... and I dont usually have the space to bring it way up there slowly.

Several production cars get to just over 200mph with a little more than 600 hp. I suspect it would take about that to get the Z there. 600 hp should be about 480 whp on a Z.
Viper 206 mph 640 hp
SRT Hellcat 204 mph 707 hp
ZR1 Corvette 205 mph 638 hp

Can confirm a stock Nismo will do 155 without difficulty.

1slow370 · 09-11-2014, 01:58 PM

I've done 155 under moonlight with no headlights, true story never doing it again.

how hard were you afterwards though?..........

Thought I was going to have a heart attack. As a side note the factory brakes can only stop her 3 times from that speed before they go full fade.

I have a video of me riding on the stock speed limiter, which was indicated as like 156ish according to the needle. Back from when my car was mostly stock, just test pipes/wheels/suspension, or maybe I had the exhaust on too.

But, it was on public roads and I am passing cars... so I cannot post it because I do not want to get banned!
