Turbo Zetec Dyno

[striker2]

ok i finally got a picture of the dyno plot. as you can see something is not flowing enough air up top. Hector thinks its the 2.5" downpipe. i think its not helping but i dont know that its the main contributer. i think i have either some collapsed lifters or i have maxed out the cams (after looking at several foci running almost 300HP on stock cams im starting to believe the cams themselves are not the problem).

meh, I GUESS its okay.


... I guess.

I doubt its the downpipe. ADC kit came with 2.5" downpipe and people are making 400 whp on that.

I bet its the cams, that power band is extremely similar to that of a stock zetec motor, just on a much higher level. I think its just the way the cams are tuned on the stock head because you get "lower" end torque/power that way. Get a better cam, I bet your power band will go much higher.

find me some stage2 or 3 cams for the hydraulic lifters and ill think about it.

in the process of replacing my LCAs (that sucked) i removed some of the intercooler piping. one of the pipes i removed was the BOV pipe. when i take it out i notice that the snap ring was not seated all the way. so i reset the snap ring and finished installing my LCAs (did i mention that sucked). during the test drive at WOT it is no longer running at 10-11:1 and it feels like it has more power up top, although it does start to lean out a little (12.5:1 so im not worried yet). i guess it was just enough of a leak under boost that i wasnt getting all the air into the manifold even though the gauge still read 10PSI

i need to get a few things done and then i will start slowly turning up the boost. then i need to find a dyno in the Kentuckiana area.

I too second the notion on the cams.

[striker2]

like i said, if someone can find me some cams that work with the hydraulic lifters or can tell me what it takes to convert to solid lifters of use of the focus cams im all for new cams.

Seems you have plenty of exhaust side pipe diameter.

What filter you running?
What MAF?
I wonder how much valve overlap there may be on that engine you have...
How much timing is being pulled?

[striker2]

What filter you running? right now its a generic cone filter. it was the only one i could find easily with a 4" outlet. K&N will be ordered eventually.
What MAF? Lightning 90MM
I wonder how much valve overlap there may be on that engine you have... factory valve train so whatever it is from the factory.
How much timing is being pulled? not sure. ill see if i can find out though. i know he went pretty aggressive on the tune cause its only 10PSI right now.
