Your correct about flow, but on the EXHAUST side. PSI is PSI. Your CFM of the turbo determines what you can push into the engine, yes, and how efficient you can maintain a pressure. But pressure is pressure. 28 psi is 28 psi is 28 psi weather the turbo is off a fork lift, a semi, or a sentra. The difference is how much heat and flow is behind that pressure, which is where power comes from with a larger compressor wheel. Less heat, more flow. So in regard to the intake manifold, cfm wont kill the manifold, it is just pressure. The added heat of a smaller turbo obviously does not help.

Say your blowing through a straw into a pressure gauge with a balloon on the end. your trying to pop the balloon. With a small straw, you have to push the air a lot harder to build the pressure to pop the balloon. With a larger straw, you do not have to push as hard, and the balloon pops sooner. It took X PSI to pop the balloons in both cases, or really X volume, one way was just more efficient than the other.

As for the head stud thing; I ran 24 psi on my qr with normal arp studs without issue. On the jukes I run normal ARP studs well north of 28psi. Shit, the 400 whp 28psi juke I built was on OEM Nissan Head Bolts. Same diameter as the qr ones (i had not sorted out what studs from arp fit at the time and said fuck it)
Fair enough. Pete from v1r ran 24 psi and saw coolant issues on his 700+qr he holds the fastest 1/4qr in a b13 in the 9s i think he would know what psi is safe with which arp stud. Mind you this is strictly track car 8500rpm at 160mph in 4th gear

not saying you shouldn't, I was more focused on the intake manifold thing, all i was saying in regards to the studs is that its not 100% required at a certain point. A lot of factors play into it.

Yeah man very very nice car. Dont be afraid to take a video.

I also was concerned about the manifold. I think about that often. Ill probly only see ~20psi on high boost but if its documented to hold up beyond that, Ill try not to worry about it. Thanks for sharing.

Also I think you will be just fine on the rogue crank ;)

Appreciate it man! my car/build is all over my Instagram 👉staticdrivenspecv👈 videos too need to get a more in depth video made sometime in the future but first its dyno time 🙂

Sweet. I'm annoyed with this fuel pump project I'm trying to figure out lol. Just trying to hardwire the pump and bypass the oem relay so I have constant charging/ battery voltage to the pump I have a 30a 12v relay installed in the trunk (battery is In the trunk) but I lost where to go from here I have one pin going to the battery with a inline fuse one pin going to the chassis ground one on going to the fuel pump power and not sure where the other goes ..another write up on this site says connects to the fuel pump connector side whatever the hell that means ...I was experimenting with priming the motor by unplugging certain wires to see what functions what and the only wire the pump seems to be worried about is the black/yellow wire which is power..why do we even have 5 wires then ? Makes no sense if I de pin the black/white green and green/orange wires together leaving the black/yellow and the black it still primes if I remove the oem relay nothing happens so something is still wrong and I'm sure it's this last pin for the 30a relay just not sure what wire I need to tap into now

pin 87 on a relay goes to the thing you want to power on when the relay turns on. pin 85 is 12 sw+ and is how you signal the relay to kick on with low amperage power. Make sure that is a 35+ amp relay. If you are running 30A through it continuously and its a 30A relay, its going to get insane hot and possibly fail. Always go bigger on relays. Your going to want a 8 (at the smallest) gauge wire, and if the relay terminal doesn't have the same material volume as an 8g wire, then your going to have a hard time getting full amps through the relay itself.
