Well to say I'm pleased would be an understatement. The first run was 161.5hp and 155fpt, run 2: 165.61hp and 160.10fpt. Run 3: (removed the air cleaner element) 167.38hp and 162.18fpt. run 4: (mocked up a ram air for the air box and set a small fan in front of it) 171.68hp and 163.97fpt.
To recap:
Dyno runs HP TQ A/F Comments
1st 140 151 10 Car had 146k, Mods: FR 9mm Wires, K&N drop in filter, Autolite D-Plat
spark plugs.
2nd 142 152 10 Cleaned uim/lim, IMRC quit working during this session.
3rd 149 151 11.5 New Bank #1 O2 up stream, New IAC, New Coil pak, changed oil in
MTX to Valvoline Synth Power ATF, repaired IMRC
4th 151 152 12.5 Installed 98 SVT ECM and SVT 19lb. Injectors. Not the power gain I
expected. I figured the cats were done in and that the ECM needed more
Intake and Exhaust flow.
5th 171.68 163.97 13.2 Installed my own designed exhaust 5A. 165.61hp 160.10fpt
Mocked up Ram Air/fan 5B. 171.68hp 163.97fpt
Also for this run I changed oil to Valvoline 5w20 Synth Power and added
a can of Restore, I don't know if it helped with the HP but the car no
longer smokes.
The cost of Mods to this point:
K&N $0 was in the car when I bought it.
Ford Racing 9mm wires $52
Used SVT ECM and injectors $100
Custom Exhaust: $200
I'm not listing the cost of the other parts as they are maintance items that normaly would be replaced do to age or failure.
Total cost of Mods:$352.
To figure the cost of HP/TQ increase per dollar I'm going to use the 149HP/152.07TQ figure as the starting point due to preforming normal maintance got the car to that number.
171.68 - 149.50= a gain of 22.18HP/163.97 - 152.07= a gain of 11.9TQ
$15.87 per HP increace/$29.56 per FPT increase
As soon as I can I will have the sheet posted on my Blog
