i had a posting awhile back about freshen up my motor well i did a compression test it was 200 psi at 250 rpm all around and also had it on dyno to day and ran it 3 time the best we got was 156.95 hp and 121.56 trq in 4th at 9k rpm what do you guys thing is it necessary to do a freshen up at 105k mls timing belt and water pomp was done at 90k mls

 

give us some more accurate info on your car mods etc then we can help you better
it just depends on the shape of your motor , burns oil , rings are bad or needs a rebuild etc. do you have a chart of the dyno you can post up?

 

your owners manual should be able to tell you what is reccomended at 105k

 

assuming you checked all the obvious. Those numbers don't tell much. Those numbers corrected? These motors can vary greatly

 

r01516 (7:15 PM 9/10/2008): well my motor is stock and this is my 1st time on dyno so i dont realy know how to read it and my teacher and i did the compression test and thos are the numbers we got

 

also what kind of dyno was used? is the ECU stock also?

 

how about starting from the beginning with an oil change new fuel filter and new spark plugs was this on a mustang dyno becuz those read lower than a dynojet would did you try a pull in third gear is your car modded how about using periods next time you post so its easier to read. Just a thought

 

see if you have any leaks in the head. i made 164 and 120 tq at around 8600 with i/h/e and ecu .
and i made 200 whp with upgraded cams and injectors and ctr pistons at 8000

 

the motor is 100% stock. just the clutch is not. not sure what brand it is though, but that shouldnt matter.

i talked to him on the phone yesterday, he mentioned a fresh oil change/filter before the dyno run.

compression results were 200 across the board, good deal i'd say.
