Well as is you can see my numbers in my sig which are probablly closer to 300whp with the new dp. Ive been running that way for 3000 miles with very little problems... im currently on dsm450s which are maxed out because of no fpr... my plans are to run 2 more lbs of boost with bigger injectors and a more conservative tune in hopes of netting about 320whp ish... as is my afrs were 11.5ish... so my question is to others who have run around 320whp ish mustang dyno, how long have your motors held together?

My 330 dynojet WHP B16 lasted about 10 passes at the strip and one hard pull through all four gears before the ringlands let go. That was on pure 110 octane.

ive made two passes at the drag strip (a 12.8 @ 120, and a 12.5 @ 118, both at 7psi)...

but every once and a while ill step on it on the street...


its been boosted for ~30,000 miles, and a year and a half. gone through a couple headgaskets however.

290 whp at 9-10 psi, will be more once I get my 3 Bar. Been boosting for about the same time as you. Then again I will be building my new engine, during my cold *** Canadian winter.

to all of you guys what have you done as far as tuning, cuz obviously u can make it last if you have the right tuner.... blundar has tuned and will be doing the further tuning on my car... you might recognise him from his article in honda tuning magazine...

for tuning you want to keep it as conservative as possible. with an aggressive tune you are more likely to blow something

at 70psi rail pressure on 440cc's you should be at 80% duty cyle at 335whp, Your running 450's so you should be plenty fine. Get a decent FPR and Gauge and run a higher pressure. You'll be burning much more efficiently and its a hella lot cheaper than having to up your injector size.

The higher pump pressures help vaporization of the fuel by making a more finer mist. Breaking the dropletts up even smaller. Id suggest only going to 80psi as a max of raising tho. But for the power your looking for 70psi should work great.

which fpr do u reccomend that i could use with the stock fuel rail...

well I'm running a B&M FPRw/ B&M gauge. I did have an InlinePro Rail i was going to use w/ an inline style regulator but I changed my mind and went with the stock rail and B&M. (a friend offered me a B18b bottomend for the rail so I went with the OEM rail instead)
