What-his-name wasted countless hours and dollars supercharging his Zetec and he ended up with, what, 170hp?
i believe you are talking about Hector who is a highly regareded CEGer. he still drives a 4 banger.:laugh: its a very fast 4 banger at that.
my point is that just because its a 4-cylinder does not mean that the engine does not have potential.
Lets do some math.
the standard duratec comes with 170 hp. 85% of that (drivetrain loss) is 144.5 hp at the wheels im gonna assume the average ceger as atleast done intake and exhaust so ill say 150hp for the duratec at about 6200rpms and has a displacement of 152.5 Cubic Inches.
VE=(5600*hp)/(rpm*CID)
VE=(5600*150)/(6200*152.2)
VE=.89
the engine is about 89% efficient meaning its only using 2.225L of its displacement.
now for my car which has intake, exhaust, and 230K miles. ive put it on the dyno and have these numbers to back it up.
121 Hp@~5800rpm at the wheels so i dont have to calculate drivetrain loss.
122 CID
VE=(5600*121)/(5800*122)
VE=.957
so my car has a VE of about 96%. it uses about 1.92L of whats available. thats only a .305L differeance. the stock zetec breathes better from the factory than the duratec. the potential is there. most of this site doesnt see it however and bash the zetec like its just a little $#!^box engine that cant make any power no matter what (proven by your statement about hector only making 170hp)
this brings me back to my point that you can spend a total of about $3-4k and have a nice little zetec that will outperform the standard duratec that you could have bought for the same 3-4K that includes upgrading the suspension to out manuver it also. for another 2-3k you can be pushing similar power numbers as a stock SVT and still out manuver it. so your looking at about 6-7K for either a nice stock SVT or a modified zetec that outperforms it in every aspect. and if you can find good deals on body parts, looks just as good. the reason most people dont do it is cause they dont have the knowledge to do so. instead they spend the 6k on a stock SVT or mildly modified SE.
as for why hector didnt make anymore HP, i assume he didnt want to risk blowing it up as it was his only ride and daily driver. you also realize that it wa 170HP at the wheels through an ATX which means he was making anywhere from about 210-230 HP at the crankshaft. he could have very easily made more power if he wanted to. he still wishes he hadnt sold it.
