NEW BEST AND IN THE 9'S!!
Went to track on mon for a rental with some buddies.
New 4.30 gears got the 60' time down to consistant 1.38s and 9.81 ets at 138mph. 1/8th mile was 6.2's at around 110mph. Last tire gear combo was 28' tire with 3.73 gear and best was 10.18 at 134 Now it is 4.30 gear with a 315 m/t drag radial (30"). Think there is still some left in it! This is all motor,pump gas.still 11.3:1 comp,468 c.i 455 block Was shifting at around 7300rpm,went through traps at around 7000-7100rpm. Ill get some vid up. __________________

Still same converter,a 9" continental,stalls at 4800rpm on transbrake. Slip comes in at around 6%. I was leaving off a 2 step,worked my way up to 4600rpm leave. 60's were consistant 1.38s all day. Old 3.73 gear/28" tire combo was doin 1.53 60' but thats was leavin off a 1500rpm footbrake. Gonna look to see how i can drop 60' lower then 1.38,i think there is more et in it with the 138mph. Also cldnt look at afr logs till i got home and found out i was way lean at 13.5-13.7 afr!  so maybe a little power left in it to!

Great run Congrats!
It is amazing how close are cars are setup. I have a 9" Continental, same gear, same size tire, 3.5" exhaust. I hope my 60fts as good as yours does. |

FWIW, an old table I have which has proven very accurate in my experience, shows @ 138 MPH an ideal chassis setup would yield a 1/4 mile ET of 9.75, 1/8 mile ET of 6.17, 330' of 3.96 and a 60-foot of 1.34. If so, it would mean you do have a little more there, even at your current power level. And, if your MPH goes up, even more room for improvement.
Again, great job! That's a huge change from tires and rear end ratio. Gets me to thinking. Jim

It's amazing what a little tweating dose. Right gear...getting the converter
right and a little money, to do these things. Yeah I believe there's another tenth or two there.

It would be interesting see if the ET improved with the addition of a cage, even though you're adding weight.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
