    Odometer shows 21,000, has to have turned over. Car shows better than most with 21,000 on them, as noted above.

    87 Astroroof GN for sale - Chicago Area

    Thanks 99...motor has less than 3k miles, probably less than 2500 so no on the seals. And yes you can eat off the motor if you choose :) If you mean could i have made bigger dyno numbers by leaning it out some and/or adding timing and boost absolutely. But I wanted to know how much power I...

    87 Astroroof GN for sale - Chicago Area

    Hi there, The time has come to sell my 87 GN. I've owned it since 2005 and it has been great, but hobbies change and our local McDonalds killed the cruise night in town so I really don't use it. I am very picky so consider the description that follows conservative...you won't be disappointed...

    Chassis Dyno Tips?

    Chassis Dyno Tips?

    no AF was in that range. But we did have some big knock numbers, they were not real. See my other post on that.

    Chassis Dyno Tips?

    Knock...See my other post too! We did see some knock and it was hard to decide if it was real or not, especially with AF ratio coming down instead of up. Could have been rich knock, rather than lean since the AF above 5K RPM was about 10.9 or less. I'm definitely looking for people's...

    Knock with Forged Pistons?

    At the dyno today the guys working mentioned that a car rebuilt with forged pistons that didn't originally have them will have very different harmonics. Thus the knock sensor won't behave nearly like it should. I was getting some wierd knock numbers today, that would come/go for no real...

    Chassis Dyno Tips?

    Results! OK, just got back, not bad I would say: First hit was base 19/20 lbs boost, base fuel curve, 5.5 on the alky knob made 370HP 448TQ at the wheel. Not locking converter. Last hit was 24/25lbs boost, plus 5% fuel, 6.5 on the alky knob made 411HP 544TQ. This was good air, the...
