You going to make and sell any more of your plenum? I'll buy a plenum if you do

Nice bro. I have same project. Hope 512whp too

Fuel Avgas with 104 Ron
Piston n rod = CP n hbeam
Head stud Arp
Turbo PSR G35
Its possible 512whp @26psi?

*Fuel pump walbro 450lph and injector 550cc
Your pushing shit up hill with 550cc injectors. Likely to run out of fuel

Upgrade 1000cc and push 30psi my engine strong Enough with those specs ?

Hey, as @6A13TT TYPE S said those 550cc are too small, you need to go 1000cc +. Also you have a built buttom end so that's a plus. All my builds so far is on stock internals so you should have no issues reaching your goals
@Silvervr4cibodas I have over 400awkw on my single turbo build and running 3 fuel pumps (1x Walbro 255 in the tank and 2x Walbro 460 in surge tank) with 1350cc injectors.
Very interested to see how the G35 pulsar turbo performs for you.

Its the high boost threshold thats keeping these stock bottom ends alive. 300ftlb doesnt hit till 5krpm
If the turbo came on earlier youd be making more cylinder pressure (torque) at lower rpm where it has more time to transmit force to the rods and bearings. and that ultimately is what kills rods, bearings and stretches head bolts.
The higher in the rpm range you move the cylinder pressure the less time that force has to wreak havoc on the components. Until you obviously reach a certain RPM limit where Valvetrain stability or conrod tensile strength becomes an issue.
Case in point the single turbo car i completed recently makes 300ftlb (400NM) at 3800rpm and I wouldnt risk that on stock rods. It could make more power even earlier too if we were to run it on ethanol based fuels instead of the pump 95ron it was tuned on. But this is a street car running on street fuel. It only makes 460hp on 21psi but light to light i can guarantee that this car will be faster than the car that makes 80hp more (540).
On a drag strip itll be a different story and a Circuit race situation will be different again. but it all comes down to how the car will be used. And how much lag the driver is willing to put up with. Depends if your racing dyno sheets or racing cars

Yeahh bro. I got 504 hp @22 psi on dyno dynamic. I try on track 1/8 miles 7.5sec but its too much spin. Shifting @8200rpm. To preven the pump oil issue I install accushump/dryshump. Next target 600 hp next year

Yeahh bro. With 550cc fully duty so I cant push my engine.
