I'm thinking mine is getting tired. 107 is about all she will do. I have a block in my garage with 40k miles on it (rebuilt by Rotary Performance, Dallas) I'm thinking about installing it. I guess I should do compression tests, and all, but I think it's just showing it's age. I'd like to know what others get out of there's on top end. Stock only, please..

 

I went around 130mph in 4th gear. If I remember correctly, the engine was at around 8,000rpm. 5th gear didnt make any power since its an overdrive gear. Make sure all your tires are in balance and your brakes are in good shape when your doing these high speed runs. Also, please dont make this kind of run with other traffic on the road. the last think you need is some guy pulling into your lane.
When your going that fast, your going to run up on people so quickly, they wont expect you to be there.

 

Very true, but people never expect me to be there anyway, someone is always getting over on me or cutting me off. I made 120 in my car, its got 172k on it.

 

Are your 5/6th ports working correctly?

 

135 downhill in 5th when I first got my car.

 

Mine hit 146 and it has 90,000 on it. It can't do that anymore though. I am lucky to hit 130 now.

 

I'm pretty sure my 5th and 6th ports are working. It's pretty strong at higher RPM's. I probably could get more out of it in 4th gear. I don't want to sling it apart though.

 

I can hit 235kph. That's around 147 mph

Around 6800rpm in 5th gear running a 0.801 5th gear.

Well, I have some mods .....

 

I hit about 140 mph in my 88 SE when she was stock. This was at 7500 RPM in 4th gear. Redline is 7k.

This took me probably two miles or so...lol.

I haven't tried with current mods...which are in sig.

 

I hit 140 in my 90 GXL, with about 135k miles on it at the time. It was still accelerating. I don't know what it would have hit. That was on a flat highway.

Edit:That was the indicated speed, I don't know how accurate my speedo is.

 

134 mph in 4th is fast as mine will go an that is with a new motor. These cars for the most part go faster in 4th gear than 5th.

RXXXED

 

i was at 120 at about 4k rpms in 5th.... had much more to go, still pullin, but i ran out of time and *****... never on that highway before. 87 stock gxl w/ 90k miles

zak

 

about 127 according to my speedo. At the time i had just under 48,000 miles on it. I was in 5th and ran out of straight road. 0 Mods

 

127-128 was all I could hit with full RB exhaust and HKS intake
