Ok, so im just throwing around potential mods willy nilly in this forum, but this one seems like it might actually be worth it.
After reading the whole of that Puma Racing tech site, and emailing them, I think the $800 odd that I was looking at putting into brakes would be better spent on performance.
I rang Advance Performance Center (thanks jr) who put me onto a bloke name John Hill I think. He specialises in engine engineering, much like Puma Racing. He has quoted me $770 for full porting and flow bench work which will give about 20-25% more power right away. This will take my est. 164hp up to over 200hp, the magic figure of 100hp/litre I am after.
John has done the head mods on the 405Mi16 Targa Tazmania car which was at UQ for the Grand Display, so at least he has seen one head like mine.
Furthermore, the 16v engine has large valve seats that will take 2mm larger valves, seeing a 10% increase in size and arounf 8% increase in power, but this would be about $600....diminishing returns.
Anyway, has anyone had any experience with head porting and flowing, either doing it or having it done (engine head that is
)?
Are these figures realistic and what downsides are there. I REALLY dont want to loose the low rev tactility of the as I rarely rev over 6000rpm. I am more interested in a better power curve rather than pure HP, although 200hp would be sweet.
