Can my non-flex fuel pump support 450 whp? thats my power goals with my new setup and i was curious. Ive tried searching but im getting mixed reviews. new setup will be a 67mm turbo on low boost. and by low i mean 6-8 psi.

 

What year truck

 

2008 5.3. non flex fuel.

 

So in 5 years nobody has tried to push a stock pump?

 

I've run it to 600rwhp or so.

 

Thank you. Thats all i needed to know. i only plan to push 450-500 at the most.

 

You will need some good sized injectors. Your fuel pressure will go down with increased flow and so your delta pressure will take a dive as well. FWIW, I haven't got a clue how much power I'm making, but my truck is flex fuel, I'm running 60# injectors, making a maximum of 8psi, my injector duty cycles hit 95-100% and my delta pressure goes down to about 36psi.

 

I ran a non flex fuel pump to 10psi on a TVS2300. The fuel pressure did start to drop at that boost level though. I ended up spraying meth as a suppliment.

 

This is EXACTLY the route I'm taking. Talked to Julio at Alky Control this morning. Ive got a 2 gallon Trick reservoir and I'm going to send it to him to modify for his system. It will be set up to activate through MAF frequency so it can be a true daily driver meth system.

 

Monitor your current WOT fuel pressure at the rail and then report back.
90%+ IDC results in too little leeway for any legitimate tuner to optimize the combination, and increases the likelihood of melted pistons.
