Gee, guess I will let the cat out of the bag. He he! I compared a stock TB
with Patricks R&D TB. Here are the results:
RPM Stock TB TQ/HP RD TQ/HP Results
with RD
3500 328.4/218.8 332.7/221.7
+4.3/+2.9
4000 325.5/247.9 322.4/245.6
-3.1/-2.3
4500 332.7/285.1 335.3/287.3

6000 265.1/302.8 263.1/300.6
-2/-2.2
Stock TB made peak power at 5500 and RD at 5800. Both had peak torque at
4900. After 4700 the RD made 6-7 ft/lbs more then the stock and 5-6 hp more
(all though the numbers above dont represent that till after 5500. I didnt
want to spend all day mapping this all out from 3500 every 100 rpm!!!)..
Note that after the stock TB falls off at 5500, thats were the RD starts
really working. Till 5900, where it drops big time, then picks back up.
Thats as far as my dyno sheet goes: 6000. If anyone wants copies of the dyno
sheets, e-mail me private, I will scan and send.

P.S. With the RD TB and a reworked computer the motor made 360 ft/lbs at
4800 and 347hp at 5600. Another interesting note: with fuel presssure
DROPPED to 30psi, it picked up 5hp at peak and dropped 2 ft/lbs at peak.
