ProCharged Time slips
2001
8/24/2001
Bob's car is finally back together,
and we've been slowly working on the tune, while Bob has been working on his
driving tecniques. Mustang's car number was 7353.
Tires were 28x10.5 MT ET drags. Boost was set at 14 psi. Temperature was about
70F. Fuel was 116 VP Racing fuel. Initial base timing was set at 10 degrees
and the Interceptor was used to retard WOT timing 4 degrees. Rear gears are
3.27s and shifts were made at approximatly 5700 RPM.
At this point this was the car's fastest time to date,
Bob (with a very big grin on his face) headed back down to the staging lanes
to give it another shot.
Not bad as far as consistancy is concerned. This pass
had a slightly better 60' but was just a touch slower for the remainder of
the pass. At this point Bob was qualified and waited till the first round
of eliminations.
Allright!!! Now that's getting somewhere! After talking
to Bob, best we can figure is that he left softer out of the hole which helped
keep the tires hooked. Hopefully he'll be able to repeat this in the future
or maybe I can find someway to detune the car for launch. Either way I have
a feeling that we will be seeing single digit passes out of Bob's ride as
soon as the cooler fall air gets here...

Bob's Mustang
car number was 7353. Tires were 28x10.5 MT ET drags. Boost was set
at 14 psi. Temperature was about 70F. Fuel was 110 VP Racing fuel. Initial base
timing was set at 10 degrees and the Interceptor was used to retard WOT timing
4 degrees. Rear gears are 3.27s and shifts were made at approximatly 5700 RPM.
Bob rolled through the burnout box with his D-1 procharged
mustang and improved again!
Nice! He returned to the pits and I told him I wanted
to remove 2 degrees of retard from the engine at max boost (add 2 degrees of
timing) He said OK, but don’t blow it up, and walked away while making a couple
comments about damn Sitar wanting to lean it out…..I grabbed the Interceptor
and brought full boost timing up by two degrees.
Bob headed to the lanes again.
My jaw hit the floor. If two degrees of timing did that,
how much more is left in this setup? When Bob got back to the pits I don't
think we could have beat the smile off of his face, I told him I wanted to
remove the last 2 degrees of retard that are being pulled out by the interceptor.
At this point the car would be running on a completely stock EEC IV and I
think it could improve to at least 9.70s maybe even 9.60s. Bob reminded me
that we did not have the cage certified yet nor did he have a license…..details,
details…..I left the timing alone and added 4% more fuel at full boost to
slow it a little and Bob ran his last time trial.
Bob said that that’s just right as he put his 10.00 dial
on the window….His car is still running only 14 psi of boost, all passes are
made through the mufflers, the car remains completely street legal and passes
PA state inspection.
