150 head on a S1 Elise?

[L100NYY]

The S1 Elise that I've just purchased has the following mods to the 'engine':

Janspeed straight through exhaust (no cat) :ears:
ITG induction :cloud9:
150 head :confused:

The query I have is what is the 150 head exactly? Oh and any guestimates on the power output of my car?

Your thanks in advance :thumbup:

depends who did the headwork really - it may be a Janspeed ...if its lightly ported with maybe bigger exhaust valves then with your other mods you shoul dbe making 140bhp+ ...if it has different cams too then maybe 150bhp

Cheers Bogie, i's only so that I've got a rough idea as to be totally honest it does feel very quick and doesn't feel any slower than the 111R I'm using.
