boost a pump by kenne bell?

[klaasjoe]

Has anybody used the kenne bell boost a pump on their 7m or 1jz? I am gonna use it on my mustang but was thinking about getting one for my new 1jz build. Let me know if anybody has used it and if so how did it work out

it would be nice if you had posted a link- so here: http://www.lingenfelter.com/Merchan...ode=KB89067&Category_Code=C307&Store_Code=LPE

Kenne Bell, The Innovators, have done it again: An ingenious, reliable yet simple solution to your fuel system needs. Just tap into your existing fuel pump wiring. Imagine 50% more fuel delivery and horsepower without the hassle and expense of draining and removing the gas tank, tapping into fuel lines or adding a noisy in-line pump - and it doesn't heat the fuel up. The Kenne Bell BOOST-A-PUMP is fully adjustable from 1% to 50% with the mere turn of a dial, so pump output can be varied to match your engine's needs. No longer are you "locked in" to a fixed pump capacity and/or pressure. It activates ONLY at full throttle (naturally aspirated) or at 3 psi (turbo or supercharged). And it acts as a voltage regulator by compensating for any and all system voltage fluctuations.

So you actually expect 50% more fuel delivery out of your stock pump? Doubtful, at best. Would you actually trust the stock pump being pushed that hard? If so, you've really got to re-evaluate your decisions. Seriously.

Another note- You'd rather spend $240+ on something that'll likely end up melting your motor, rather than a $100 Walbro or MKIV fuel pump? Yikes!

This is one of those things that you don't do, as far as I'm concerned. What exactly is it doing to provide 50% more fuel delivery? I would imagine it's pushing past 12-13v, which, if I remember correctly, is the operating voltage of a Walbro. (maybe 14v max?)

That's just my take on it, hopefully others with more knowledge than me will chime in.

Ah, but you have to look at it the other way around. It can REDUCE flow as well...

Interesting product, might be nice to have a huge loud pump and get it turned down so it's not so loud and it doesn't have to cycle as much fuel through the system...

Fitting a Walbro pump isn't hard and they arnt that loud unless you have a stripped interior like mine. Look at a flow chart for a stock pump V a GSS341 Stock pump at 60psi = 30lph GSS341 at 60psi = 196lph.

the paxton booster pumps are the same thing, but with out mustangs we usually have to bump them up to a 255 walboro, then the booster on top of that.

they don't work as well as expected, and cause alot of the older stock pumps to fail. that's why everyone goes with a walboro

Agreed.

When I bought my N/A Supra, it needed a fuel pump. Since I knew I'd be going turbo someday, I spent the $100 and installed a Walbro. Best $100 I ever spent for the piece of mind knowing that I'll never have fuel related problems because I did a half assed job on my fuel pump.

I still have the stock interior in my Supra, and I can't even hear the Walbro.

It is a popular upgrade for my particular stang. I have the 01 cobra but with an 03 fuel system. I dynoed at 575rwhp but now am running out of fuel at 13 psi I want to pulley it to around 17psi. I dont really want to go with an external pump yet and have seen alot of good results with the boost a pump. it has already been expensive just getting the upper and lower intake,fuel rail and injectors. I just thought that maybe someone here tried it on their supra with a walbro and I was curious about the results.

 

[klaasjoe]

Thats the kind of info I was looking for. From kenne bell they say on an 03 dual intake pump which is what I have you can go no more than a 20% increase which is probably a little more than 14v. So I guess your saying that the walbro cant operate safely over 14v? Now would it make a difference that this a a boost activated regulator? it only comes on after like 5psi

 

[Insidious Surmiser]

forcing the pump to work overtime?
sounds like a terrible idea to me, just go ahead and get the appropriate fuel pump for your fuel needs

 

[Supracentral]

Using $250 piece of electronics which performs a questionable action to replace one $85 pump that has been proven to work time and time again = stupid

Next.

 

[deabionni]

Out of curiosity, have you considered using two Walbros? I've seen Supra owners use two Walbros to meed their fuel demands with great success.

Even the cost of two Walbros and some fabrication to put them both in your tank would cost less than that $250 boost pump; and you wouldn't have to worry about burning up your fuel pump.

Mike,

Did you ever find out from your dealer what the Walbros were rated for voltage wise? Someone else might have been looking into it, but I thought it might have been you...

The answer I got wasn't 100% what I was looking for. It was something like "the pumps were designed to be used on vehicles with a properly operating 12 volt negative ground electrical system"

Meaning they don't want to step on anyone's toes. Overvolting an electric motor is rarely a good idea.

I don't like boost a pumps (and I have worked with them before). It's a solution looking for a problem.

It's still easier (and cheaper) to run dual walbro's.

Overvolting an electric motor is NOT a good idea.

fixed :biglaugh:

at what hp level do you more than just 1 walbro? will 1 support around 500 rwhp?
