Good luck man..Lets see a +700whp non sleeved block!!

 

I think the Warbro 255 in tank is failing!! It won't even fill the surge tank at idle
I think I breaking into it's GASHOLE to swap the pump

Good to know that the failure rate of the Walbros is so high. Especially since I just bought one of the piece of *****.

I really don't want to be like Kevin and have to reach up my cars gashole to switch the damn thing out all the time.

 

Ready to high boost map! Pressure drop fixed. The Walbro was not bad, it flows well over a gal. per. min. Here is a link to the problem.

We find that 9 out of 10 issues are install related..

 

All those woe's from a .0001 cent piece of rubber, ugh!!!! Glad you found it man, lemme know when your next tuning session is

 

tghat .00001 cent piece of rubber could have caused major catastrophie..

 

That chunk has been in there for over 2 years!!
I changed out the pump last summer because of pressure drop, it has been causing fuel issues sense day one. I still can't understand how that big piece got in there in the first place!
This might

 

Way to kick it's @ss Kevin!!! ANYONE WANT A BARELY USED FUEL PUMP!!!!
See Kevin
Jman

 

Always have to blame the G***HOLE don't you?

 

Back to Mac tomarrow for more tune, 1:30p till.... I run out of money!
Jason is kind enough to be there again, Juztin, feel the flu coming on at about 1:20???

Damn if I didn't have to go see the VA doctor tomorrow! However I'll be there Thursday. Hopefully you'll be all tuned by than though.

 

i might just have to drop by tomorrow...

 

If only i had a witty and clever way of getting out of work to be there!

 

LOLOL I'll do my best to be there buddy! I may bring a video camera along as my buddy let me borrow one and I'm still trying to figure out how to use it and all that.

 

Fake diarrhea? Or say you got the vomits

 

I like your thinking

 

Not good!
Any boost over 11.5psi causes the fuel pressure to drop at the top of the boost.
We are at a loss, I need some info from AAM on the stageII system I have in, why it is doing this!!
Did see a high # of 640rwh 531tq, but this was not consistant because of the fuel pressure drop!!!
?????

Kevin how much boost was that horsepower at and at what rpm? I beleive I have a pump here that you can use for testing if you think the Bosch is taking a crap.It is a big *** SX pump and you can plumb it in for testing purposes.We have used these pumps on 800+WHP cars.It is loud and obnoxious but gets the job done.

 

I'll send you the graphs on all them. I'll call you tomarow.
