Hi,
in stock ready to ship.
From our experience on track the 2.5 was fine at 450 BHP all season in 2007 time attack, for Silverstone we cranked one up to 475 BHP 3 laps in and two split liners.
There are two schools of thought to why this happens, some say its the thin liners letting go, some say that the head gaskets fail due to the lack of support for the upper cylinders which allows coolant into the cylinder, it tries to compress it and splits the liner, whichever comes first, chicken or egg upshot is a split liner.
However, we all know a fast road car never gets the pain a track car suffers so to be fair 500 on a road car may well be fine on the 2.5, we don't like to take the risk though and cap them at 460 BHP, that's a whole lot of power for a road car, it usually comes with 460 + ftlb's of torque thrown in for good measure.
500 BHP has been seen from an SC46 Billet with 20% meth or E85 fuel.
Hope the above answers more questions than it raises.
cheers

As a road car there is very little that will touch it, as higher output turbos will take longer to gird their loins and require more revs to work, by which time you'll be off. As for lesser cars....forget it: it simply drives away from them.
Had a mate with a 996 turbo in the car the other day, his conclusion: "it's as quick as mine...... you barsteward. Can I have a go?" Since he has yet to give me a shot in his car, I politely declined

Glenn got his 500bhp on LP 930cc and upped boost! Cool! ^^^
What was the target boost? And what % meth - 20%?
On a relatively 'small' turbo/2.0, that's simply stunning in anyone's book! Just goes to show how efficient the b.b. and billet combo works.

Hi,
printer thawed out at last, Graph of SC42 Billet cracking 500 BHP .
Great result for all, turbo, mapper (JGM) and Glen, have you broke the gearbox yet.
