XR8 Sprint motor

hi guys,
just a quick question,
The xr8 sprint had a 43% larger air flow meter, larger throttle body and free flow inlet manifold. it also had GT40 modified heads with bigger exhaust and inlet valves, a performance camshaft etc... Because the sprint had all the mods on it it would obviously wouldnt cost too much more to get it to over 200kw, say 230-250fwkw right?. what would be needed to produce this and how much. i read alot of the guys with modified 5L's have unichip... what kinda change does this doto the output? any other suggestions would be great!(i.e. cams and exhaust) thanx evry1, cheers.

Re: XR8 Sprint motor

To get much more power you'll need to rev it harder..to achieve the airflow required.
The Sprint/ Cobra engine had a small std cam in them, the 1:7 rockers made up for it. Infact the Cobra cam was adjusted to allow more torque at lower rpm..Good Crane cam,springs, port std heads Gt40, better inlet, bigger t/b maybe?? Exhaust as always..Like modding a 200 kw mill to 220...

Re: XR8 Sprint motor

damn, I'd just be happy with the sprint stuff on my XR8, let alone pumpin more kw out of it.

I'd save for a vortech s/c with 12lb and push out over 300kw at the fly!

Re: XR8 Sprint motor

Strokin won't realy give you much more power unless induction etc is increased to supply extra capacity, more low end torque tho.
YEP forced induction best bang for buck no question..

Re: XR8 Sprint motor

The heads and intake are still the most restrictive parts on the Sprints. With the right heads, even with the standard cam they'll be making a decent amount of power.

Re: XR8 Sprint motor

Yes I tend to agree. The airflow restriction on these things let alone a standard e-series 5ltr are shocking.
Improve the airflow i.e. get the air in as quicly as possible and get it out just as quick.
Its all about air speed. Thats why some here have opted to go the supercharger route. Way better bang for ya buck!
