e-303 installed

slo5.0 · Jan 3, 2009

Just installed the E-303 in my car advanced 2* with 24lb injectors and 73mm mass-air calibrated for the 24's. If I go from a stop the car will take off slugish untill 3k and then it comes on good. But since it has no power untill 3k the car will NOT do a burnout!

Any ideas? Maybe fuel pressure is off or a vaccum leak??

Thanks, Matt

double check timing, doubt ur cam has anything to do with fn up the fuel pressure

We have tried 12* 16* and now we are back down to 14*. I think 14 was the best so far

Who floors it below 3000 ???

How did you advance the cam?? Degree wheel????

With the new cam your name now fits you better.........

why does everyone on here not have answers but always post stupid ****?

93mustank · Jan 3, 2009

Go out and find your own answers....dont be a baby because you cant put together a car right...

First of all your running an E cam...dont know what heads...probably stock e7's

Sounds like you didnt use a degree wheel....

Go out in the garage and get to work......

Umm u floor it below 3k when u go from a STOP. The cam is advanced with adjustable crank gear from Ford racing.

baine21225 · Jan 3, 2009

well did you have this problem before the cam install? chances are its not the cam itself but something that you adjusted/accidentally botched as you installed it

baine21225: I have had the problem ever since i got the car, but not as bad..before it would do a burnout, now it wont do crap. It wont even bark the tires from a stop...

93mustank: thanks for the help, sorry i dont have money to go buy more expensive parts like heads, and crap like u can..the car is getting faster slowly and thats all that matters.

baine21225 · Jan 3, 2009

is it a bogg and then just stops bogging once you hit 3K?

slo5.0 · Jan 3, 2009

Yes..thats exactly what it does..it will bog and then once it passes 3k it pulls good.

87gtmustang · Jan 3, 2009

have you tried looking at the spark plugs might be part of it

slo5.0 · Jan 3, 2009

Im gonna go do that when it cools down. thanks

White Thunder · Jan 3, 2009

if you had the problem before the cam why haven't you tried to fix it before....not talking **** just wondering

91cobra5.0 · Jan 3, 2009

Are u just getting it out of gear and trying to take off really fast? Or r u trying to dump the clutch and get it to spin?

If you still have stock 2:73 or wtever stock is I forget then its not gona get up and go real well

Chris951 · Jan 4, 2009

Mine kind of does this but the opposite. Engine is all stock. When I floor it, it looses power at 4500. Like you can really tell a difference. Timing maybe? sorry to thread jack

izze01 · Jan 4, 2009

u dont have a problem its just ur stock heads and intake choke the motor up top, especially since u have 4.10 gears it comes out of the whole alot faster than the stock 2.73's

qwkvert · Jan 4, 2009

sounds like u must have an automatic in it? if so, get a 3k stall converter, and ur problem is solved. I have had many older mustangs that would barely do a burn out with a stock auto and 273's.

baine21225 · Jan 4, 2009

ha, thats one way around it

qwkvert · Jan 4, 2009

I am just saying that this is a solution, but it will obviously need some gears also...then an intake...heads....headers.....stroker kit......blower.....control arms.....k member....upgraded fuel system....anti roll bar.... lightened up....cage.....lmao. It never ends does it?

I would check to see if you have any engine codes and go from there.

1slo5.0 · Jan 4, 2009

Why did you advance it 2 degrees? Is the car an automatic? If so, you need a higher stall torque converter and I'm willing to bet the tight stock converter is your problem.

slo5.0 · Jan 5, 2009

THANKS for all the info..the car is an AOD wit 3.73 gears..I found out today the car had 50lbs of fuel pressure! Lowered it down to 38, bumped timing to 16* and then found out my TPS was broken and reading 0 volts..so brought a new one, and the car pulls a little better down low, and feels WAY better in the upper rpms.
All that gas floodin the cylinders may have fouled the plugs so gonna have to check them tomorrow..BTW still wont do a burnout =(

qwkvert · Jan 5, 2009

glad you are getting somewhere though! how do u know it has 3.73's for sure though? I would just jack the rear up and spin the tire and count revolutions of the d/s and tire and find out for sure.just for ur own sanity. If it does have 3.73's, you should be roasting the tires, and need to find yourself another mustang enthusiast to help you figure out what is going on with it. I love helping when people have problems, wish you lived closer....

slo5.0 · Jan 5, 2009

We have done like u said (jack car up and spin the wheels) and its 3.73s..im lost to why it has no power down low...
The cam was advanced to help the lack of lowend torque it had..

1slo5.0 · Jan 5, 2009

Did you try the cam installed at 0? If not then you don't know if it helped anything down low. My guess is it hurt more than it helped. You need a higher stall torque converter. That will solve your problem. Anytime you use a performance camshaft with an automatic transmission you need to upgrade the converter accordingly. When you get into bigger camshafts the car won't even idle in gear without a looser torque converter.

93hatch · Jan 5, 2009

take it to the track dude, prob feels that way cuz its an auto

slo5.0 · Jan 5, 2009

I am when it opens on the 25th. Car went a 13.82 at 101 doin the boggin crap, with a crushed airfilter (got ran over lol) and unknown fuel pressure..so it should do better now most of that is fixed!

slo5.0 · Jan 5, 2009

Quick question, how do the Delta 40series sound with a hpipe? I found a pair with flowtubes and turndowns for 105bucks shipped to me.
