It´s hard to estimate the number of HPs of a modified engine but you can check
Kastners competition preparation manual to see the power gain that comes only
from a 10:1 compression and a S 2 cam.
However I found the formula to calculate the HPs on the clutch of a TR 6. All
you need to know is the exact top speed of your TR 6. You can also use it to
calculate the HPs you need to get a desired top speed.
HP on the clutch = (speed in km/h) EXP 3 / 37 EXP 3
(37 is the product of all the drag factors of a TR 6 with cw, front area, drag
from tires, gearbox and wheel bearings etc. considered . Ragtop up.)
Example for a TR 6 PI:
POWER (HP) = 193 km/h EXP3 / 50653 = 7189057 / 50653 = 142 HP
In a motor magazin a 1969 TR 6 (German version) was measured 193 km/h or 121
mph
and the claimed HPs were 143.
Example for a US TR 6:
POWER (HP) = 174 km/h EXP3 / 50653 = 104 Hp
(R&T Feb.1969 maesured a TR 6 109 mph or 174 km/h and the HP number they gave
was 104)
