Low dyno results What is wrong? 150/106
tuned/broken in on a mustang dyno @ CFT tuned by Omar i believe
crome p28
82mm lsvtec [200psi cyl 1]
b18a block milled .005
stock b16 head milled .010
68mm pro products TB
gasket matched b16 IM
hondata IM gasket
Skunk2 pro2 cams
b16 pistons
450cc inj
cheap 4-1 header [focuz]
2.25"x22" resonator >2.5" exhaust with one round 18" muffler and an oval muffler at the end [magnaflow] stock path
deleted heater core and thermostat
the machine shop that built the engine degreed the cams in wrong. it was at the 10deg mark adv. but it turned right over and idles perfect. it seems like the person that degreed them in used the wrong marks on the pulley.
so cft put them back at zero and then it wouldnt start. they worked their magic but the car was sluggish at best. they really tried everything they could do short of taking the head apart.
it made
153.8 whp
106.3 wtq
on their mustang dyno
i am planing on doing a leak down test and if its good i am going to mill the head .020 more and using a 1 or 2 layer HG.
any suggestions?
and by the way...
CFT is by far the best shop i have ever visited, they took their time and were friendly the whole time. they also took care of me when it came down to pay. great group of guys i would recommend them to anyone.
hot s2ks at the shop too
EDIT: before the cams were zeroed out the car was making a lot less hp/tq and thats why they were zeroed out.

could the person who degreed the cams in have bent them. because the head was fully rebuilt with the exception of course of the valves.
the machine shop that built the engine put it together. but he had someone else degree the cams to cam sheet specs.

i just went and checked the oil to see how much it burned during break in and it was a qt low...
when i looked under the car there is a puddle of oil and it seems to from the oil pump area.
so on tuesday i need to go to the machine shop and raise some hell because it seems like he f-ed up the engine build. in more ways than one.

Re: (formby)
I suggest you go and raise hell, but dont let them touch your motor again....if they offer, get new parts but dont let them install it
Number 1 reason i do things myself.. right here folks..
Sorry about your bad luck

i want him to do a leak down test for me when i go so i can see if the valves are bent so he can get me new ones.
why would a brand new oil pump from honda leak like that?
it seems like the seal is bad....

when the intake cam was at 10 deg and i installed the engine ir cranked and started right up. but on the dyno it made like 110/88
then we took it off the dyno changed the cams to zero and redid the tune and the best after about 2hours was 153/106.
cft seems to think that the car is over cammed and that i dont even have 10.5:1 CR with the B16 pistons. but from what i understand i should be close to 12:1....
so if the guy does the leak down and it is the valves i shouldnt let him fix it? he did tell me someone else did the degree.
and the oil pump needs to be reinstalled...does the il pump need to be pluged at a certain place if i am not using a crank sensor?
or should i tell him to buy me new valves and have him pay for another shop to fix it. i doubt that would happen...

don't let the shop touch your motor again!!
leak down test, compression? could be valves, i would take it home and check it myself, i.e. take your head off and see.
pro2's need lots of compression 12 or higher...
get a better i/h/e combo, maybe edelbrock performer x
sorry to hear man, i feel for you.
hope it comes right

i went to talk to the shop i explained the situation and he told me that he has a 90 warranty against things like this and that he would fis the problem, so i needed to bring it in if i wanted the engine fixed at no cost.
he told me that he needed to check to see what was wrong and that he could not just take my word and buy me parts.
which i understand & i am as broke as i can be with out going hungry or not paying the bills . [my 7 month old is more important than any car so i cant spend more money on this; its supposed to be the last build for a long time.]
He also did not degree the cams in a guy from a shop down did it because his wheel was bent up. so i gave him the benefit of doubt.
he picked up the car and he is going to do a comp test, check the valves, fix the oil pump and take out the pro2s and put in my old set up.
SI int/GSR exh
he said that i would see a psi increase with the stock cams. because the low psi could be overlap on the cams and he recognized the engine should be at around 220-230 psi.
i dropped off a new timing belt and some oil today and ill give him a call by 5pm for an update.

the oil pump was leaking through the main seal which he replaced and he is going to install the oem cams.
i should be picking it up tomorrow.
if another compression test comes up low and he doesnt think anything of it i will take it to another place i know to do a leak down test and do a charge back on my card

My engine dyno reads 13% higher thana Jet, therefore the Mustang reads 28% lower than an engine dyno, WHY ?are they just that dumb? or is the dyno just that bad? If your Trans is sucking up 28% of your power, it done siezed, along with your wheel bearings.

82mm ls with b16 pistons should be reading way more.

82mm LS with b16 pistons should be like 270-290psi or more... My 81.5mm LSvtec with ctr pistons last time was 300psi across board.

Change the header to a hytech or something along those lines, different intake mani/TB .....u might already make more power with just the oem cam setup lol
