Got Over 400kw Atw?

Kenne belle pump voltage boosters are popular in the u.s with the supra crowd

Usually running weldon 2345a 's and massive singles on e85

Could switch them on or off via boost switch aswell

I have been thinking of trying the voltage booster on my 044, rather than going twin pumps and putting more heat into the fuel. ( its already an issue on long drives.)

Anyone seen good results from them? How much more would i get out the fuel pump ifbits close to max flow now?

[sky30]

This is where im at with stock fuel line size and 044, couldnt push anymore boost as it was maxing the injectors, i have some id1000 to try but suspect the pump/ fuel line may be close to its limit.

Is that on petrol or E85?

[zebra]

What turbo is that?

On RB30?

His sig says RB30DET with GT35/40@24psi

What injectors do you currently have sky30 ?

[sky30]

Turbo is gt35 with billett comp wheel, injectors are 750cc

[SiR_RB]

Pretty much my boost and power levels

I think the stock fuel lines could support more power

up to how many volts can the walbro e85 pump run safely ? I thought 14.4v was the limit

Why you think that?

[sky30]

i have run a Kenne Bell Boost A Pump since 2004. i find it an easy way to solve the fuel flow challenge of our thirsty motors. especially nice as it only juices the pump while in boost.

given the rotary needs about 30% more air to make similar output to a piston motor, it also needs 30% more fuel. in addition, it needs to run on the rich side at higher power levels and then there's E85 which requires 30 to 40% more fuel.

there are many ways to get it done and most work. you can do multiple pumps, or one monster pump or swap in what is currently the best 21st century single intank pump, the Walbro 9000262 (gas) or 9000267 (E85).

if you are approaching 600 rw on E85 the Walbro may be marginal.

at 13.5 V the pump makes 389 L/H

at 16.0 it makes 568!!!!!!! more than enough for more than 600 on E85.

at 16 V the pump is happy BTW.

of course life can't be that simple. Kenne Bell just changed their BAP to a 17 V minimum... which is too much for the pump.

/////////update: the 13.5 V base model is back by popular demand, see post 11 in this thread/////////////////

other than an FYI on this i would like to ask the board, someone who knows electricity better than me...

would it be feasible to run the BAP at 17 V and add some sort of resistor so as to end up at 16.0? if so please add the specifics.

I coppied the above from rx7 forum. Intersting that the walbro 460 will flow 568 l/hr compared to 389 l/hr at 13.5volt

[SiR_RB]

Pump life at those volts ?

Sounds promising...

The post was made in 2014 and says he has been running one since 2004 so 10 years and still going.

What pump and injectors you running, and what duty cycle the injectors at?

[SiR_RB]

Walbro 460 and id2000's

Not sure on injector duty

They would have plenty left u like the pump...

Ive been thinking of trying a walbro, but not sure they flow much more than the 044 at high pressures.

What power are you at with your set up and are you having fuel shortage issues with the pump/ fuel line size?

[Lithium]

Turbo is gt35 with billett comp wheel, injectors are 750cc

Is it still the HTA86?

448kw @ 24.5psi on caltex eflex (E70)

Pump is at it's safe max limit

I rekon lines can flow more if I had more fuel flow
