Increasing top speed?

You are probably gonna need better oil coolers, big brake kit, coilovers to lower the car, better tires, forged wheels. then pray the motor doesn't blow with repeated pulls.

Shep is amazing! Had their ultimate racing trans in my evo 8. They do some amazing work

I bet that even people in countries with no speed limit on public roads like german autobahns rarely drive >200 on regular basis. Once to get a feel? Sure. Every day for hours at top speed?

Thought our cars topped out at 168mph? This was on a supercharged car so maybe a stock car doesnt have the power to get to the end of 6th gear?

Ya, stock doesn't have the power to max out sixth gear

Not my car but it was someone from this forum. Maybe one of the CSG guys I forget. Pretty sure the car was supercharged though. you get to about 168mph and then you run out of gear.

Well I was in Germany for a good year and more. I had my e46 m3 there and I got to tell you people fly over there on the autobanh. I prob drove about 140-150s on the normal long stretches. But cars would fun past me like its nothing. But yes not often do you see people go 200 that's insane.

200 more rpm before fuel cutoff :P

Hence the about 168. Could probs squeeze a few more mph out of it. Raise the rev limited in the tune and maybe get a few more if you have the ponies to push it.

I've done 135mph personally. OFT Tuned E85 EL

km/h. Highest I got on stock was 232 km/h, but it's not a pleasant experience.

OP, power and aero dynamics hold the stock car back from a higher top speed not the gearing. If you are turbo however, a taller final drive may help you achieve a higher top speed.

I did 131 with passenger in the car. Then get caught by copper right away...../facepalm

First, is to find a place to do it safely

Second, make sure their aren't any incoming planes.

Then, after you reach about 130 mph, I'll betcha you won't want to go any faster in this car ....

I suggest putting a sail on top of the car.

Is that Bremerton? It's been so long since I've been home.

The first picture is of the airstrip at JBLM (Joint Base Lewis-McChord) near Tacoma.

The second landing strip is at Swanson Airport, near Eatonville, WA.
