New Best

Made some changes yesterday on the 68`.

Removed the .920 t-bars and installed .880 t-bars.
Swapped 90/10 shocks replacing OEM style.
Removed sway-bar.
And.......changed the blower drive ratio.
Went from 2.23 ratio to 2.72 ratio.
Made 3-lbs boost @ 2.23 ratio
Now makes 6-lbs. with 2.72 ratio.
Took it for a drive WOW! what a difference...

So went to Quaker again tonight expecting to see improved hook and more power,did`nt exactly work out that way.
#1 1.71-60ft. spun bad lifted at 1,000 hoping to stay above 11.50.
#2 1.69-60ft. spun [Email]11.50@116.23mph.[/Email]

#3 Backed timing down to 28* and did harder burnout right up to the starting-line.
1.56-60ft. PULLED left wheel off the GROUND!! WOW ran [Email]11.35@115mph!!![/Email] New Best

Now the bad,,,, trans. has waved the white flag.
Slips into 3rd. Its a stock rebuild with my manual-valebody thrown in it.

What I learned this trip:
When it can get on top of the tires and spin on the street its a beast,feels ALOT more powerfull at 6-lbs boost than 3-lbs.Even at 30 MPH in 2nd gear it will come around under throttle.
More boost didn`t make any faster only harder to hook up. 3lbs versus 6lbs no real gain
More RPM on the shifts improves MPH,,slows E.T.
More timing is quicker,but harder to hook.

So I`m thinking for max performance: more gear,more converter,more traction........

Nice Dennis! nice RR.. mine's a lot slower LOL

Nice going. Congrats. Ron

uh oh

Mission Creep

Congratulations!

So me knowing almost nothing about boost: is it true that if you raised the boost to 14.7 psi then you would effectively doubled the displacement of the engine?

Then why didn't the mph pick up when you went from 3 to 6 psi?

good job, when you get traction don't be shocked if you break something out back. Good luck getting the trans worked out.

I`m having fun just seeing what it will do right now,has already exceeded my goal.
I would need to put in a roll-bar to really go much further.
Getting a 1.56-60ft. and getting one wheel off the ground was a suprise!! 3.30 gear and stock converter??? Never would have beleived it

I am yet to understand how I doubled boost and saw no power with it.
Tried less timing/more timing/ jet/RPM no real benefit............

I am VERY happy with its road manners/driveability and would have to really think long and hard to ruin that.....
Overdrive????
