Sure. Stock cadillac ctsv makes 485 whp on this dyno. Stock focus RS mashes 318 whp on this dyno.

But it's inertia so mine looks like it spools late. I also live AT sea level. Was like 5 C in shop that night so cold dense air.

update to a 100mm cooler mate

Solid 11 mid to low 11 second car there Adam  a car I built was tuned by Yavuz. It ran 11.3@125 with 330rwkw

I see 3.5 in Trust exhaust and instantly think TR  One of the best exhausts ever made for any Nissan!!!!

My R32’s previous config was setup as a Targa car, roughly 300kw @ the wheels using a pair of GT-SS's and some supporting mods.

It was time for a change – my new setup is focused on track days.  To be clear up front, I’m not chasing dyno numbers here!  The brief to RacePace was to build it once and give me a responsive engine with reliability. 

·      N1 Block

·      RacePace stage 2 2.8

·      9 litre sump

·      100mm Intercooler

·      1,000 cc Injectors

·      Borg Warner EFR 8374 T4 1.06A/R

·      Twin 40mm waste gates

·      98 PULP (E85 on the cards in the near future)

I'm super impressed with the response and looking forward for its first track shakedown..

My New R32 GTR
Stock RB26
Stock dumps
Greddy downpipe
R34 GTR Intercooler
Garrett -7 turbos
Intake Pods
17 psi boost (looks like cut on top end)
Same dyno as used on my old car
93 octane pumpgas (USA)

Dynos start at 10 psi and move up from there.

Great fun to drive. Makes half a bar at 3000 rpm.

Hi do you know what rpm full boost?

I had a similar setup (except the .92 IWG) and would make 20 psi at 3600 rpms if I punched the car from 2k in 3rd. 30 psi before 4k rpms. Stroker 2.75L on new N1 block and stock bores. Almost same power on pumpgas.

I see that this dyno is in question. On my previous post you will see new garrett -7 turbos (extremely similar to N1's) on my RB26 car which is a stock engine with greddy downpipe, HKS hi power exhaust, and intake pods on 18-19 psi boost. We are making the exact same HP at 5k and the curves look VERY similar aside from your max power. I find hard to believe that this is a stroker engine on those turbos. It's either a stroker on -5's or is a really healthy high-flowing 2.6 on the -7's (which I find more believable). Check your stroke by running a rod in a spark plug hole and measuring high and low of the stroke while you roll the engine to know for sure.

32psi

Same turbine housing as mine. Your dyno figure kind of matches my results. All things being equal... 580ish @ 32psi hub dyno figure vs. 530ish @ 26psi on a roller dyno.  I'm looking forward to seeing what mine makes at 32-33psi.

 

Looking forward to seeing your dyno sheet to compare response between the RB26 vs. RB25/30. Also looking forward to seeing what MPH yours runs at the drag strip.

Thanks for reply. That’s great result. What power it made on what psi? I’m looking for get 8374 iwg or 9180 iwg. But no result I can find.
