Rb 2860-5 Highest Hp?

[Jc052685]

As instructed ........

What is everyone's thoughts?

Just got my car tuned 703rwhp 524rwkw. Does anyone know the record for these turbos?
Built bottom end with 87mm pistons
2860-5 turbos
Pon cam type A
Tomei manifolds and dumps
Apexi down pipe
ID1000s and tomei fuel rail
2 walbro 400lph fuel pumps
Nismo inlet pipes and hard intercooler pipes
Custom intake pipes
AEM series 2 ecu tuned for flex fuel

So I'll start this off by asking what have you modified on the turbo to make it more efficient in some way?

[sneakey pete]

I'm interested in hearing what you've done to the intake system, if you're willing to give away any of those secrets

[Jc052685]

The turbo its self is unmodified.

[Blackkers]

Need trap speed to confirm a result like that

[Jc052685]

Simply a dual 2.5" Maf-less system I built for it. I am wishing now that I used 3" as I may have left a few hp on the table. I welded 2.5" v-bands to the turbo inlets as to minimize the inlet turbulence that a couplet could induce. Took care to make sure all inlet pipe fitment was perfect.

[Jc052685]

I personally feel that if the customer wanted to truly max out the turbos by freeing up some restriction that still exists in the inlet & charge pipe sections that I could get another 25-35whp out of them. Car is still on the factory intercooler & intake plenum after all.

[mr skidz]

You're in Inlet pipes might be 63.5mm which is great but you're inducer is like 47mm from memory.

yep

Lol I think ur s14 550hp is bullshit as well only trapping 129....my Aus 500hp went 135...

[Piggaz]

What's done to the head apart from drop in cams?

[sneakey pete]

I was talking about post turbo piping, apart from the nismo (I think?) Merge its stock cooler and stock plenum etc?

your race weight?

I was at 3260lb.

[Jc052685]

No more nismo inlets I am assuming Ricky? lol

[Jc052685]

I am curious what everyone thinks this setup actually makes?

[XKLABA]

Got a pic of the cooler, Nismo is not factory and there is two versions with one being far superior to the other

Looking at the parts list I would say the exhaust and ID1000s are the most limiting factors and would guess a realistic 400-420rwkws and give or take 130-135mph

[Jc052685]

Intercooler is factory. ID1000s are running 97% at 58PSI base pressure.

[XKLABA]

List says Nismo cooler, factory cooler starts to measurably pressure drop from around 350kw, 500+rwkw on a stock cooler is where I call mythbusted

Nismo intercooler hard pipes

Car made 490whp on 13psi...... Mustered a 507whp pull at about 15psi but the 93 octane pump gas was the limiting factor.
