did you ever upgrade to a double pumper?

i agree with cursedsm's statments to a point, i think you should have done more research before you purchased 3 turbos for you car.... you could have got the ef4 to spool quicker with more fuel, timing and ecu boost. then when you decide to tap into more power you would have had it already there.

 

No. I have not nor do I ever plan to purchase a double pumper as I can make the power that I need with a single Walbro.

Again, the issue was not the EF4 turbo as I stated that I had a pre-turbine exhaust leak that I thought were lifters that need replacing. It is not an issue of turbo research as I know what the stock IX turbo can do as well as the FP Red. At the end of the day, I tried the EF4 and it is too large for how I use my EVO here in southern Arizona.

 

Levar is looking for a smaller turbo that spools sooner giving him more response and torque downlow.. i don't know what the big deal is.. Levar wants response and torque over peak power at high RPM's (top end).. nothing is wrong with that.

Quite honestly before i became a tuner to the public that is all i was about on my personal cars.. spool time and all the torque i could get downlow.. Now im trying to go fast at the track so my goal has obviously changed and now i am sacrificing low end for top end..

Levar doesn't want more then 500WHP, so why would he stay with a laggier turbo when there are others on the market that will spool quicker and make a broader powerband for him to use and still reach his 500whp goal?

Honestly the FP red is still large.. a FP green or BBK full could get the same result, but i think hes going to be satisfied with the Red.. and when he updates his fuel pump he will have the opportunity to make more top end then either turbos i mentioned are capable of achieving.

 

Tom, this is what I have been trying to explain all day, my friend. I thought I was making it clear about my goals and intended use as they have not changed whatsoever.

 

500whp+

400wtq+ < 4,500 RPM

Insane power band from 4,000-8,500 RPM

Single Walbro on E85

 

When are you expecting to have the red on the car? Should be a fun daily driver.

 

I estimate that it will not be until next week assuming the turbo is shipped as I have been told.

 

you will make 500 on e85 but you are taking a huge risk if that one pump were to fail.

 

Single pump failing...? Would that not apply to everyone that runs a single pump or is that based on how much power I will be making? I was thinking about a Walbro 400lph for an added peace of mind. Thoughts?

 

Levar, I feel as if the 400 will suit you quite well, especially since you are not looking to push a ton of power, but are more after a simple, reliable setup. If you need more, re-wire with an AFPR.

 

definitely get the buschur double pumper if you get anything. stay away from the rest.

 

Understood, my friend. I will order it Monday.

Are you talking about this one...?

You beat me to the punch, Tom...! I live on mi iPAD and you are still quicker than I am. You believe that it is double pumper or bust, right?

 

the br double pumper is the easiest solution there is.. and the great thing about it is you can keep your stock FPR and all relays in the car.. no need for rewiring the pump or doing anything that can effect driveability, startup, etc..

I recommend the br double pumper because the car will still run normally on 1 walbro 255 as it is now cruising around town and it will drive the same.. sacrificing nothing.

once you get into boost the hobb switch then kicks the 2nd pump in, so you're essentially only still running 1 pump unless you pass a certain boost pressure.

trust me.. go with what i say.. i have a lot of experience with these cars.

i have been running a br double pumper since 2009 and have zero complaints.

 

Done!
