what is the approximate horsepower and torque on the TC 88, 96, and 103 engines with no modifications?

 

That would be next to nothing, damn little, and completely inadequate, in that order ......

 

I would guess HP about 65, 75 and 80 with torque values about 10 points higher than the HP, ( or what hoofnhog said)

 

Are you talking about HD "advertised" specs or are are you talking about actual measurements at the back wheel?

 

LMAO
Capt Morgan & coke out the nose....

 

Good answer, lol.

 

stock anything is lame...we always make the last guy to the watering hole buy the first round!

 

64.8 66.3 69.9

 

If everyone here is accurate, the 103 is not much of an improvement over my 88. I'm running slip on exhaust, SE air cleaner and 204 cams, after the dyno tune my numbers are 70 HP and 80 torque. those numbers are certainly not earth shattering, though they look really good next to the 25HP my 45 Flat Head puts out.

 

Really hard to top hoofnhog's reply but, here are some dyno numbers I've seen:

Stock TC-88 - 55 HP, 60 TQ
TC-88 with Screamin' Eagle Air Cleaner and V&H Big Shot Staggered - 58 HP, 63 TQ
Stock TC-96 - 65 HP, 80 TQ
TC-96 with Stage 1 Kit - 70 HP, 85 TQ
Stock 103 - 68 HP, 85 TQ
103 with Stage 1 Kit - 75 HP, 90 TQ

Take those with a grain of salt. Unless you run them all on the same dyno (which these weren't), the variance in results can be staggering. I've seen cases where two supposedly identical dynos would give results that varied by more than 10% (with the same ambient conditions).
