Low HP (Tork Tech)

[bakos24]

13psi Thats kind of high for there standard kit. Did you change out any pulleys?(not saying this is your problem) I am seeing about 9psi with mine and still using the SVT fuel pump that came with the kit and have no problems(besides the one you know bout already)
You should defiantly be near my numbers with your mods. Even on a very, very conservative tune, those numbers are really low.

Yup 13psi on the dyno, and i'm seeing 10-11psi on the streets, i didnt change any pulley.

I'm starting to hate this car, first the radiator problem, and now this

did u sort out your problem?

is it possible to go to a different tuner?

I'm off tomorrow, so I’ll do the compression test 1st, and see the result, if every thing is fine (which I hope) then I’ll try another tuner.

Ok guys, i have done the compression test and below are the results,

Cyl#1 165psi
Cyl#2 165psi
Cyl#3 couldn't test it
Cyl#4 couldn't test it
Cyl#5 145psi
Cyl#6 160psi
Cyl#7 155psi
Cyl#8 155psi


the reason i couldn't test Cyl#3&4 is because its location under the tork tech intake, which is PITA to remove as some of its bolts are behind the blower in between the blower and the intake, with the tools i had its not possible to reach them.

but what do you guys think of the result above?


something else i have noticed is the condition of the spark plugs, see the pictures below,

the plugs are from cyl 5,6,7,8

all of the plugs are showing that the car is running lean, except for cyl#6, it looks different

Plug#5

Plug#6

Plug#7

Plug#8

Plug#1

Plug#2

the guy that was helping me today said i should take out my injectors and test them at a workshop because of the difference we found in plug#6.

do you think that is related to the issue?

What kind of plugs are you running?

I'm thinking it has to do with the tune...

Assuming cylinders #3 & #4 are similar to the rest, the compression seems fine. Before you go changing any more parts, I would consider taking it elsewhere and having it redynoed and the A/F ratio rechecked just to ensure it isn't an issue with the dyno calibration or the tune. What kind of dyno was it you were using? Dynojet....MustangDyno?

I'm using TR6's.

It was a Dynojet.


And to compare the A/F, i have connected my AEM wideband to SCT analog input and dataloged it, i think its similar see below picture

This is a vid of the car drive by after the dyno, sorry for the bad quality

have you datalogged the timing? and the iat's?
