Thread: VE+t swap project ...REtuning with ALKY injection soon

pump and injectors more than likely, 470's @4 bar are safe to right at 550whp, Along with the walbro 255 pump. I pushed it to that and would not go any further. Injector duty cycle was pretty much maxed.

A 550whp SR is very easily had with very little money as well including the built motor. But to go further than that requires some major money in comparison. My entire setup and built motor cost me only 4500 to do, that was including cams.

Like they say, gotta pay to play.

Cant wait to see some great numbers at low boost levels from your setup man.

I have 1000cc injectors , and I have a intank walbro , I have a spare walbro.....but I still am thinking of sumping it and using 2 of the external walbros or 044s but we will see

550whp is very doable on the walbro pumps. Seen it a lot anyway.

Yeah, a single walbro can max out around 600whp depending on where you make your power and how much boost your running to get there. Whats on your side is your making that much power at such a lower boost level compared to the normal det motors. So less fuel pressure and stress on the pump to keep up.

Ill be doing a Walbro in tank feeding a bosch 044 inline. That setup is good to 750-800whp with a base fuel pressure of 100psi. Ill be using 1000cc injectors as well.

have you thought about e85. e85 with the fuel setups we run for the aem ems is easy as converting the fuel maps to a higher pressure of fuel, then a little bit of fine tuning for the afrs and that would be about that. there is alot of potential with e85, whats really drawing ym attn is the fact that the gas is only like 2.35 verses 3.10 here in ohio

But doesn't E85 require actually bigger injectors and a higher volume pump in order to flow the equivalent energy per volume of regular gasoline??

I saw your thread about this ...and we have talked about it this winter when we add more fuel capability , and then we will go to bigger inj. and possibly an inj. driver to run them more stable , and then do some changes to the pump gas tune to accomidate the lager inj. , and then we can tune it to its potental on E85 , because E85 is not avalible everywhere up here , only in like 1 place and it is 14 miles from my house ,but that way I could just flip a switch over to the NOS map and run E85 switch it back and run pump gas it will be interesting to see how it works out , but it looks doable with lager lines and two external or internal walbros

Correct. You need about 30% more fuel delivery capacity (volume) for the same power output with E85.

that is why I will need more pump-pumps , and larger injectors and possibly the driver box for them to run more better then just using the drop resistors ...

This seems to be your best bet as well Eric. The work it would take to do dual Walbro in parallel doesn't seem worth it to me when you can just add a Bosch 044 to the system in-line and get plenty of fuel. Sorry if this turns into a fuel pump discussion. =/
