hmmm...so what you're saying is that though I AM blazing bye right laners, I'm actually closer to the limit than I thought? Cool! I guess I need to press down the ole right foot harder!

Hey guys instead of speculating.

I can;t figure out how to post a link to a thread in Rennlist.

Anyways, look up the user name "jim morton" in the 944 turbo section (there are only about 4 threads).

There are posts in one of the threads talking about radar verified top speeds in a 951 during open road racing.

Anyways, that thread a 951 was clocked at a max of 178 and had multiple clocking over 170 during a race.

Does that give an idea of what one will do?

With stock gearing and stock tire diameter and stock rev limit, you're not going to get much faster than 170 without bouncing off the rev limiter. There is no doubt in my mind that a well-tuned and modified 951 could top 190 with the right gearing.

DanaT

That could be true.

However, you made two assumptions. 1) Stock tire diameter and 2) a stock rev limiter.

I tend to believe the radar numbers, especially since there were multiple clockings over 170.

I am not disagreeing with you. That's why I made those assumptions explicit in my post. Also, I made three assumptions, you forgot that I assumed stock gear ratios as well. I didn't think it was necessary to point out that no race car would fall under all three restrictions, but it seems I was wrong about that.

You'll further note that I stated that I have no doubt whatsoever that a properly set-up 951 could top 190.

I broke my personal record! Today I managed to get the needle at 270 km/u (= 168 mph) on the Autobahn. I think it was just passed 6000 RPM.

Pretty easy to hit 190 IMO. Vitesse turbo kit, 7100rpm rev limiter, and 18" wheels/tires will definately do it. I hit 189mph with my rev limiter set to 7000rpm when it bounced off it. Just a few more revs and I would've cleared 190. It was pulling at a fairly slow rate up to 189mph. Would've pulled harder if I had cams since my TQ starts to drop off near 6000rpm.

Such a slacker rage!! LOL Would adding a couple of pounds of air in the tires give you that extra 1mph??

Rage you're right. 18 inch tires will do it. I've done 194mph...

DFASTEST951

Oh, and I was at 6800 or 6900 rpm. Tried not to look at the gauge too long while going that fast...lol

My modified electronic limiter is set at an odd number of about 6875 RPM, or something like that. I have 26" tall tires and hit the rev limiter at a real 304 km/h which is a hair under 190 mph.

DFASTEST951

Way to go! How did the car feel? Do you have a front splitter?

Mike Murcia

I'm too much of a woman to bounce the limiter in 5th, but I'll ask a question to the brave...

What size 18" tire are you fellas running? By my calcs, a 26" tire (285/35/18) will hit 194.7mph by 7100rpm. If you went one size over on the stock phone dials (235/50/16) 190.1 could be seen by 7100rpm, so I don't really see the advantage to 18" tires. Does the extra rubber slow you down?

they are talking about rim size not tire height

hehe 26 inch rims on the 951
