Hung Like a Stang

so I don't run her hard, as much as I should...or maybe thats a good thing depending upon how you look at it.

Anyway, today I noticed some bogging when I floored it. I hadn't noticed this before, well at least I don't think so.

but anyway, I felt like going a little faster so I floored it, and it went, but i could hear the engine bogging, and there was no power.

I have been having that hard start problem.

One thing I think it possibly could be is my fuel pump, I have a 255lph with no reg, and the return system might not be able to keep up with the flow of the pump at WOT.

what do you guys think?

i'd definately invest in an adjustable FPR

gearbanger

+1 yup you should do that...

I've been running it w/oa reg for months and havn't noticed a problem before though.

My MSD box did fail me yesterday, do you think the extra spark could have kept it going before?...

89 fox

very possible......you are losing 20* of spark timing

do you even know what fuel pressure your running WITHOUT A REGUALTOR AND A HIGH VOLUME PUMP.


Fix that asap man and replace them plugs before you blow the engine. and replace the O2 sensors if its a slug afterward still. Hope the cats are not melted either

stock pump had me at 54 psi unregulated no ,my meter was not malfunctioning i guess your alot higher than that

and change your oil , its more than likely contaminated

um, i don't think its that big of deal. I was at like 38 psi with a stock pump.

stock=110 you have 255 38 x 2.5= WAY TOO MUCH!!! i'd definately check into it man

aode08

if it was at only 38 psi with a stock pump UNREGUALTED, THAT PUMP WAS SHOT

they put a fuel pump regulator for a reason, to keep a steady Psi and Volume, the injectors and ecm can only take so much then its washing down your cylinder walls.

I wanna c a picture of your plugs too,. and dont clean em
