This will be a long post. If you help me, I'll really, really appreciate it. :SNSign:
Went to the track yesterday.
Last year, I was running low 13s. My basic setup was:
-Stock 5.0 from oil pan to throttle body
-AODE with B&M shift kit, stock torque converter
-Zex dry 125 shot
-4.10s
-190lph fuel pump
-Aeromotive fuel pressure regulator
-BBK-off road H-pipe, flowmasters
-BFG drag radials
-CAI
My best ET was obtained from launching off idle on the nitrous. Here it is, complete slip:
60'-- 1.943
330-- 5.685
1/8-- 8.710
MPH-- 82.32
1000- 11.268
1/4-- 13.343
MPH- 104.48
So this year, I made some changes. Here is the setup from yesterday, with changes in bold:
-94/95 Cobra intake manifold
-Proffesional Products 70mm throttle body
-Professionally rebuilt AODE w/"race grade" internals
-Edge Racing "Street Edge" 3000 RPM stall lockup torque converter
-Powertrax "No Slip" locker differential
-Stock rubber intake tube back on
-Zex dry 125 shot
-4.10s
-190lph fuel pump
-Aeromotive fuel pressure regulator
-BBK-off road H-pipe, flowmasters
-BFG drag radials
I ran four times. Here's the complete slips and their background:
Run #1: I wanted to be cautious as this was the first time I'd be spraying 125 with the new found airflow from the Cobra manifold and throttle body, so I bumped fuel pressure to 46 PSI/vacuum on. Also, I didn't know until after I left the track, but my plugs were gapped to .040, which is the gap I run with a 100 shot. I forgot to gap them for the 125. I launched off idle into the nitrous and spun both BFGs a bit:
60'-- 1.989
330-- 5.705
1/8-- 8.827
MPH- 78.33
1000- 11.535
1/4-- 13.819
MPH- 98.22
Well, MPH was WAY down along with ET, so I figured I was rich and dropped fuel pressure to 43 PSI/vacuum on.
Run #2: With fuel pressure now at 43/vacuum on, I launched off idle into the nitrous again. I turned the juice off during the 1-2 shift here, but didn't really need to:
60'-- 1.927
330-- 5.787
1/8-- 8.972
MPH- 77.20
1000- 11.711
1/4-- 14.006
MPH- 100.42
Run #3: With an increase of 2 MPH, I dropped the fuel pressure to 41/vacuum on. I launched again from idle into the nitrous:
60'-- 1.888
330-- 5.678
1/8-- 8.828
MPH- 78.05
1000- 11.537
1/4-- 13.808
MPH- 101.51
Run #4: I dropped the fuel pressure to 38 PSI/vacuum on. I tried launching the same way as the previous three runs...and the tires BURNED the **** off! I blew the tires off and had to completely let off the gas and get back into it...results were horrible and will be abreviated:
60'-- 2.582
1/4- 15.002
MPH- 95.49
Summary:
After adding a Cobra manifold, 70mm throttle body, rebuilt AODE w/"race grade" internals, "Street Edge" 3000 RPM torque converter, Powertrax "No Slip" locker differential, and the stock rubber intake tube I lost .5 off of my ET and 3 MPH (when I expected to GAIN .5 and 3 MPH!).
HELP!
