HP conversion

[Opntop@aol.com]

A friend of mine in Belgium has a supercharger setup in his otherwise stock 
TR6 which he had tested on a dyno. The reading taken at the wheels is 135 KW in 
3rd gear at 5500 RPM's. He tells me to multiply that figure by 1.34 to 
convert it to HP, which gives me 180 HP. Could anyone verify this ?
Thanks and Happy New Year to all.
