Unforgiven
solid fixture here in the forum
Now on to something else, I have problems with belt slip with my 177 blower, if i ease in to throttle it makes boost, but if i mash the loud pedal (kickdown) it makes hardly no boost, how much tension do you have? My tensioner rest in the middle, seems ok?
its a 10 rib belt.
Thunderbolt...... the 85-90 percent was using a 7" lower pulley along with a 2.85 upper pulley and the belt in the pic below.
That was the race engine set up.
The replacement engine which is in the truck now uses the same belt and top pulley,
but I installed a 6" lower pulley.
The tension pin is at 50 percent on this combo. The pic below has a red arrow of
where the pin sits with an 7" lower pulley.
The pic below are the log results of the backup engine...350 SBC 0.30 over.. stock cast iron 64cc chamber heads... 10.5:1 static compression...cam has .501/.501 lift.
Don't recall the duration, but it works for a back up.
No where near the power output of the race engine....but as Coty keeps reminding me...it still runs!
I highlighted the numbers in the left column . it shows what happened at the point where the WHITE crosshairs are on the right.
It was about 95 degrees with very high humidity ....Take note of the MAT....it only reached 101 degrees F at 7.6psig boost.
The afr's are on the e-85 scale
