    Thanks James. This is a project I'm working on with Owen Wuillemin. The aim is to produce an exchange head/cam package that will work with the std. engine management on a 205, be emmission legal and produce 100-110 hp at the wheels. The head in the picture has had metal added in the chambers. After machining, it should flow and burn more efficiently via improved chamber shape and increased C.R. At this stage I'm having trouble with the tool path, but once resolved, we'll cut a wax model on Owen's CNC mill. I'll keep the forum posted.

    hi peter. u said this head and cam package should produce 100-110 hp at the wheels. i have a 205 gti 1.9 and understood they had 130 horse standard. is this a flywheel figure or is your head/cam set up on a 1.6 gti.

    Fly wheel figure dude

    shame 130 at the wheels would be sweet

    A std. 205 1.9 has approx 75hp at the wheels.

    So if your'e formula is correct I have 176kw at the flywheel !?!? Hmmmm.

    Have you had the head under the cnc mill yet ?

    A couple of known benchmarks. A 2L Mi16 has 116kW flywheel and 116hp at the wheels. A 200kW Holden has 200hp at the wheels.

    Sorry, haven't been near the mill.

    I can see you're point, is this coincidence for these particular cars or is there something karmic in this.

    What is the actual hp/kW conversion ?

    the conversion for kw/hp etc is 1hp=0.7457kw or an easier way i remember is 100hp =75kw

    PeterT,

    Have you any idea on a cost for your head/cam exchange?...and what do you find improves, torque or power at higher revs?

    OK, i'm back on it. I've ordered some new software which should speed up creating the chamber surface. The idea is to create one 3D surface of the completed chamber, which the milling tool will follow.

    Cost? I've got no idea yet. Depends on milling time, guides, hand finishing etc. Guaranteed to be awesome though! It definitely won't need 44mm valves though!

    Peter, what size intake and exhaust ports do you propose to use. Any other porting ? How about valve springs and cam timing ?

    After reading <a href="http://www.pumaracing.co.uk/pug2058v.htm" target="_blank">http://www.pumaracing.co.uk/pug2058v.htm</a>
    I'd start with stock valves if they're in good condition. 43mm if new ones are needed.

    Pete,
    Is this 100-110 bhp at the wheels based on putting the head on the catalysed 1.9 8V motor that we 'know and love'?

    What is normal percentage used for drivetrain loss in a 205?

    Would be interested so please keep us up to date

    100hp would be about the same amount of power @ the wheels as a Pug 306 Style with the 2.0L 16v motor (which is rated at 96kw or so from memory).

    That would be quite sweet in such a light car.

    Cheers,
    Adrian

    I didn't think there was any interest, and 8 valves had died a natural death. Glad to see some interest! If people are keen, I'll keep going. The original aim was to get 100hp @ the wheels, which is appox. equal to 100kW (135hp) flywheel, using the stock ecu and cam. I think it's achievable given a stock UK 1.9 GTi was "supposed" to have 130hp. The remachined head will have higher CR (aiming for 9.5-10:1) and better combustion swirl. I'm going to use the stock valve sizes first, then try larger valves later on. New big valves will add big $ to the project. A friend has a new cam ready to add to the package, which should be good for another 10hp, hopefully still with the stock ecu.

    I'll keep you all posted.

    Keen to hear how things develop. Definitely interested in more KW evil but not keen to bolt in twin cam mallet . What sort of cost can we expect?

    I'd expect an exchange head will be $1500 -$2000. Won't know for sure until I find out the CNC machining costs.
