Injector Leak Down test

[VP_07SRT8]

im looking to get my injectors tested for efficiency and see if its time for some new one

any one know where i can get one i was thinking Ford?

 

[stang8u]

injectors are like water pumps they tell you when they are going bad thers a spot on top of them that seeps fuel when there going out get a set of ford racing watch ebay you can get a good deal just make sure they are new thats some thing you dont want used i got my 30#s 150.00 retail 299.00 befor tax

 

[stang8u]

it is good to also use some good fuel injector cleaner every so often injector nozzle holes are very small and not hard to clog

this is what im thinking about doing :

thats cool but new bigger and better is allways the way to go do you work on your own car

 

[VP_07SRT8]

yep done almost everything myself. but if i get bigger injectors ill need a tune right? i was thinking about getting new maf, TB, injectors and a tune?

 

[stang8u]

a tune is not nessesery unless you go overbord like me you just need to recalibrate the mass air to the injectors very simple and also a ajustible fuel reg

BBK makes one for my car im guessing i should get one of them too. but could i get a tune and fix all that as well? what else would i need?

 

[stang8u]

and yes more fuel you need more air and it needs to exhale i have a guy that makes costom **** for a good price i got a 3'' h pipe tucked up there beater than any 2 1/2 bbk pipe

 

[VP_07SRT8]

yeah for exhaust i got the FR ceramic shorty headers BBK O/r Xpipe, Flowmaster super 40 exhaust

 

[stang8u]

i would put in new o2 cencers and a air fuel gage too a good way to tune fuel press

well for the injector cleaner all i'll use is lucas. if you go bigger injtors@maf you can run a more aggresive tune the one thing that might limit the tune then is octane. i would watch your pipe size tho. mod motors like back pressure. the best thing is mandrel bent tubing insted of crush bends. and no cats. if you go with 3in pipes you'll probably lose some lowend torque and N/A COBRAS don't make much as it is. if you had a big supercharger with alot of boost i'd say try it, but i think you'll need it.

have you guys ever heard of the tcs kicking in at 80-110 under full throttle. the wird thing is it does't start till i get in 3rd. i can firewall 1st and 2nd and no problems.

 

[beejay31000]

weird

 

[fangs99]

yea on the first cobra i had the only time i turned off the tcs was to burnout, or for the strip. but this one kicks in hard to.

 

[fangs99]

maybe this motor is a bit stronger than the last.

I turned my TCS off permanently with my Predator. I've never had any issues other than after the last time I reflashed the car, the TCS was ON rather than OFF, so I had to reflash again, turn TCS on in the tune, disconnect and reconnect the battery, and reflash again with TCS turned off. It is normal now... OFF... LOL
