It only takes a small rock or bird or whatever to end your life.

I did my first track day last weekend at Brainerd Intl Raceway in Brainerd, Minnesota. Turn 2 is half banked then in to a lonngggggggggg wide turn. I tried 140 once and went back to 100-120. The sensation of going that fast and not going straight was...odd to say the least. So, I'm with you man. Until I have a cage I'll keep a vagina in my purse.

I've done 145 in this stock Roadster and it felt like there was plenty left, but fear of over driving the headlights and small game in the road caused me to back down. What an adrenaline rush! We have lots of flat roads with miles of good asphalt/straightaway here in North Florida

Just FYI .. thats a top speed of a stock 07-08 G35 HR sedan, but limiter was removed of course. (it did 280 km/h to be more specific).

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.

FPenvy · 09-09-2014, 11:50 AM

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

We hit that speed and stayed at that speed for almost 5km with an 7AT in 6th gear, same speed with 7th gear. The problem is the aero, not the power. You'll need a lot more power (FI) to overcome that aero problem. Oh and this is the GPS record, not the speedo on the car that has the 20km boosting, 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)?

You know you probably shouldn't say things online that incriminate you.

No, it's ok. He flew his car over to Ze Germany, and he drove it on Ze Autobahn

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.
