Thread: fuel pump selection

Tweet

No disrespect meant, by all means, but, in my opinion, if your friends are saying that they notice a power difference (as in HP) in a street car, they are probably imagining it. They think that it is so they feel that it is.

That being said, if you plan on racing quite a bit, I would go with the electric fan and fuel pump. The fan because of high RPM's (have you ever had a clutch fan sieze up. Not pretty) and the fuel pump for continuous fuel flow. I do know of one person that used to run a mechanical fuel pump and his car would starve of fuel at WOT and around 1000 ft. But that was with a lot more than 450 HP.

thats pretty much what i use it for is racing. it is my daily driver but i do cruise on weekends and street race. also go to the drag strip every friday night. i wouldnt normaly switch over but i do need a new fuel pump so i might as well go with electric and for the fans are good in stop and go traffic which i drive through everyday.

With all due respect, it sounds more like this is your only transportation, and you like to play around doing stoplight sprints and running at grudge night drags, but you still have to drive it home, and you want it to start and run Monday morning to go to work. The magazines, internet forums you're surfing, and advertising hype you're falling for are leading you astray. Go to your high school physics teacher, pose the question to him/her, and believe the calculations they do to show you that work is work, and regardless of the energy source (direct crank HP or crank HP making electricity driving a motor to do equal work) the resulting power to the wheels is very, very nearly the same. Dave (years of very real race experience) spelled out the reliability and replacement side very well; Bug pointed out that if it's a high rpm, race only application then electric might make sense; and Glenn explained the OEM system well.

Once again, do yourself a favor and replace your mechanical fuel pump, and leave your fan alone. The only thing you're going to gain is some "WOW" factor from your cruising buddies, and make your truck less reliable.

Yaeh, and he can tell his buddy's he's got MAYBE 1 -2 more HP @ the flywheel
3/4 or so to the ground !!!!!!!!!!!
I don't believe sum people !!!!!!!!!!!!!!!!!
