You don't mention what you have for a fuel system.

With your mods you can pretty well go where you like if you can get sufficient fuel and a clutch that will hold up.

Have a scan through the RB26 mods list and you will get a good idea but for ~320 rwkw you will probably need bigger injectors and a bigger fuel pump and run anywhere from 1 to 1.4 bar to get your target depending on who is tuning it.

^^^ cheers

how long can the motor hold 25psi for, will it blow up??

not if i built it...hehe

my last engine with 2530's saw 34psi and made 467kw at the tyres...on the dyno

and ran low 10 sec passes on 28psi for 3 years until.....N1 oil pump shat itself launching at 9500rpm

rev's will kill your engine before boost will (provided its properly tuned)

In terms of you wont make 440rwkw on PULP regardless due to needing decent fuel, then you need good ignition etc, its a domino effect

my interest relates to your statement of running 22-24psi then spark breaking down, obviously making 440rwkw will require fuel and solid ignition upgrades

    • He obviously had his reason for flipping you off. I wonder what it was...
    • Thats why I stay far, far away from Eastwood. only go there if I wanna eat Korean food 
    • I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal
    • HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.
    • I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
