Just thought those with a 919 would like to know the results of my budget hp mods.
118hp, 69 ft-lbs.
Mods:
5 thousands off the head
comotec head gasket .018 inch thick.
Ported intake/exhaust ports.
Cams are retarted 2 or 3 degrees due to the thinner head gasket.

Tunos and s4Rs watch out.

Nice. What were the numbers starting off?

Well, that is a bit of a story. A year or so ago it made 103hp and 66 ft-lbs stock w/ 33000 miles. Well, it has sato slip ons. About a month ago it made a wopping 91 hp after all of my mods. Then about 3 days ago I realized I put the intake cam in 1 tooth advanced.
The intersting thing is. the air/fuel is about perfect just letting the stock ecu take car of it. The lower rpms could be leaner but throttle response and rideability is great so I'm not going to mess with it. The 118 hp is with the satos, i forgot to mention that earlier and its current mileage of 46000.
