what was the pop noise as you aproached 140

 

nipper

 

sounds like a blowoff.

I believe you're correct. The car isn't mine (and I wasn't even in the car for that video), but I'm pretty sure it's a 91 SS, which would mean that it has a turbo - which means blowoff.

you probably wont gain signifacant power unless you change the injectors and edit plug gaps.

 

ps. Hit 115 mph in my 91 Loyale, 5mt.

 

105 in an 85 GL bone stock with exception to the weber and full exhaust...going down hill of course. beat that!

Back when I had my Brat it was doing around 100 when the speedo said 80+... combination of larger tires and speedo sticking at those speeds.

 

One day I opened it up and the speedo stuck around 85 and then sweeped down past 6 o'clock!

 

Yeah, downhill also.

 

 

But it was more fun following a BMW 760li in my Sport Sedan as he bounced off HIS limiter.
