Pump Gas dyno results


Wish I had another Buick!
We put the car on the dyno to tune in the FAST. Best of 13 pulls was 554RWHP and 501RWTQ. This was on 93 octane, 17* timing, and 22PSI. :eek: We had to quit before we finished after the WBO2 died on us and left us with no O2 correction :mad: and the spark plugs were blowing out. :frown: Gonna throw some more plugs in it and gap them tighter and get the trans swapped over.

Looking good. Watch those EGT's with low timing.

Maybe high egt took out the WB?

Most (maybe all) of the dyno charts i've noticed for our cars show much more torque than HP - until I read this one. Maybe because a 70 is happier over 25 psi???

That is some serious power - maybe the higher HP cars are reving a lot higher pulling the HP over the TQ in the upper revs???

we tried alky and or higher boost but ignition started skipping out so that was best we could do

I believe the car would have done better even as is since even without the alky or higher boost the ignition would start to missfire at 6000 rpm

there is 0 knock retard at the level it is now :smile:

someone asked and yes its on a 70 p-trim
