Well John, you know these big lumps of iron aren't my cup of tea, but they're certainly good at what they do, which is going as fast and as quickly as you can in a straight line for a quarter of a mile.
My ideals have been shifting a bit in recent years and I find myself following & admiring engines that do more with less. Not to say I'm in love with the little 2 or 3 cylinder engines for their economy, but more the V6 EcoBoosts, and similar engines that are able to produce > 120 HP/L at a BSFC < 0.4 (or thermal efficiency > 34%)
No, I haven't "transgendered" from a hotrodder to a tree hugger, but you have to admire the engineering that's going into the new engines that allows them to squeeze this kind of power out while maintaining such high efficiencies. Wouldn't it be cool in the future to be able to produce 500-600 HP at the crankshaft and have so little "waste energy" going into the cooling system that you could keep it happy with a radiator the size of an oil cooler?
I think Ford has taken the right approach with putting the EcoBoost 3.5 in the Le Mans car, and it'll be a real test of their engineering to see if it'll hold up for 24 hours. When they beat Ferrari at Le Mans in the 60's, it was with big heavy cars, running big heavy iron lumps that were 2x the displacement of the Ferraris, and running far less stressed (7.0 liters @ 60 HP/L vs 3.3 liters @ 96 HP/L). This time, their engines will actually have smaller displacements than the Ferraris, and will, no doubt, be running at higher BMEP's. So it truly will be an "engineer's race" in 2016.
raising thread back from a coma as to not start a new thread and not sure this is the right thing to do as a newby?
please let me know what the procedure is but plenty of good info covered in this thread already and opinions....etc
By reading this thread I find myself always cursing at how much we cant get away with in Oz, its so tiring.
Im also getting old and appreciate bit hp per L but Im not fan of excessive wiring, sensors and short lived motors
There is a gentleman named TK that has achieved 120hp at low rpm from prehistoric v8 holden engines all in cast iron
and even more from other engines with alloy heads or all alloy engines. Sometimes its better to pay someone to port
or setup your engines with a well thought of set of camshafts albeit not cheap when yo need 4 of the suckers and all
the other bits to get them to work safely but there is no reason a 1/3uz could not make good hp with todays turbos
or superchargers atw if todays Nissan vq35de can with cams, itbs, headers, exhaust and tune can make 400hp atw!
in normally aspirated tune only!!. The VQ and VK are same architecture but apart from capacity and chain drive they
are not dissmilar to the UZ, UR and many other modern V8 engines in many ways.
Also many race teams eliminate vvl or vvti for racing such as in super v8s and indy racing.
As for emissions could you run a removable cat from a similar capacity diesel truck that is easily removable and can
be shared with other people on this forum to keep costs down?
Another thing is if you look at the old mazda, ford and jaguar v6 engines they are chopped down versions of the coyote
and voodoo heads but obviously more serious cams, capacity and tuning. The ford heads look very wide but seem to
be a cost cutting exercise or modular thinking!? to accommodate larger cam lobes if need be for racing purposes.
Japanese companies seem to focus on packaging and street performance then use different castings usually when
going racing so less worried about overall spenditure. Surprisingly I didnt know until recently that Ford bought the design
that became the Modular v8 which was originally designed by porsche at some stage when it acquired Jaguar.
Now the interesting bit I would like to know is, since all these modern v8 engines have bores around 91-94mm and
similar weights all up could a flat plane Ford voodoo crankshaft fit one of the jap v8s?
After spending week researching all the worlds v8 engine from all different makes Im still sold on the UZ for its size,
build quality, weight and potential both boosted and NA (albeit NA usually costs more to achieve 120hp per L)
