4500 RPM cutout

[Blue Flame V6]

ok I was on a back road down hill decided to see what my car had well in 5th gear when I hit 4500 rpm it had a fuel cutout limiting the speed. Anyone else ever hit this? I have the gov shutoff but this was a new one.

Yes, our cars are limited to 118 mph because that is the speed rating of the stock tires.

I've got Z rated tires and a hypertech I was doing guessing by unexact math 143 mph with my new gears. I know it was 150mph w/my old ones and I hit it with those also.

maybe you should stop guessing and buy a LS1 guage. ;) sounds like my firend with his 85 z28 who says he can go 140 when his guage stops at like 85 or something

150, come on, most vetts can hardly get there.

I changed from 3.23 to 3.42 not a big one but I also got better gas mileage out of the change too. So I'm happy with it.

Well, I used to own a 65 coupe with a 4 bolt main 350, 202 heads, turb 400 and all the rest of the "stuff", then a 82 LS4, which was not much to bragg about. My sister has 94, and it runs ok, (she wouldn't let me take for a thrill ride [img]smile.gif[/img] ), my brother has a 64 roadster with the factory 327 with a 4 speed, and it is fast, but not 150. The new ones will go 160 to 180 depending on the model. I should have been more specific when I made my comments. More power to you if your car will go 150.

If you have a hypertech'just set the car for 3.42sand raise rev and top speed limiter .i have my rev set at 6000rpm and speed ithink around 147.

I hit 4500 rpm. Hmm never thought about that wonder if hypertech makes the computer think the car is in neutral
