isn't it closer to 20 extra bhp ?

I think it varies depending on how good a mood the janspeed tech was in at the time

RO55
That link is brilliant.
Got my answer......

which relates to a previous post i done about the high lift cam.
Robin reckoned i would get about 16bhp if I ported the head.....

What are you actually starting with - I cannot see a post on that other thread that has me saying you'll get +16BHP ... if you're starting with a standard 120 head and you port AND put in bigger inlet valves, you'll get +27-ish ... if you're starting with a 135, the job is a bit different and you may not get the same results as Janspeed (or whoever makes them) have already removed some metal that cannot be put back ...

Cheers,
Robin

kiwirog was telling me last year the 135r head is as near perfect as it is and best mod is larger inlets

Robin,
I've got an 2001 S2 120bhp Sports Tourer
With a Janspeed Backbox & a Pipercross Filter.

thats it......
sounds good, but needs a wee bit more oomph...

Remember, I sold a Westfield Megablade to buy this !
(0 to 100mph in 9.1 secs!)

Ah! I see - Campbell's before figure is probably quite good for a standard car - I think you'll see similar final performance as he has - i.e. it's not +16, it's more about the final head flow you'll end up with - so I would guess that even if your car really only has 120 in current form you'll still end up with a similar final figure to Campbell, IYSWIM.

Cheers,
Robin

OK - Heres goes.
How much would it cost to port the head & fit bigger inlet valves?

(approx)
