Aiming to get back to the dyno the weekend (or Friday) after the easter long weekend.

Guilt, will you be free sometime around then?

I want to wind the boost up from 17PSi to 19PSi also. Hopefully then with a bit more boost and the hi flow cat, it will crank out ~300AWKW.

It will be interesting to get a power run done on a Sydney Dyno down the track to compare results.

How did the dyno run go Bakes?

Due to Paul having to go to Qld for work I took the car to Sydney to get it final tuned. Car got tuned today by Scott at Insight Motorsports. Ive spoken to him over the phone, it made 396 Horsepower (295Kw) at all 4 wheels at 1.3 Bar.

This is with my 19 inch Volks on also so with stock wheels it will pull 310-315 All wheel Kw. Im looking forward to driving the mofo.

Ill post up graphs when I get them.

Why would it make more power at the wheels with the 18's ?

of all people i thought you would know this dude... unless you use a hub dyno.. the size of the wheels and friction properties of the tyres will affect the power output on any particular dyno.. high reading or low reading.. his volks have a rolling diameter of 675mm while the original gtr wheels are 654mm, so the original wheels will give a higher speed reading and slightly higher power reading. the big wheels will give a higher torque reading and less speed.. it doesnt matter anyway as the dyno was just used to tune it.. scott @ insight said it has got more to offer and its a very safe tune for day to day driving.. and its been tuned for maximum low down response... not top top end power.

regardless of power readings and dynos and crap thats gone on and what anyone thinks.. this car now hauls. it has fantastic driveablity, excellent fuel economy, and power to boot.. for the amount of punting bakes does.. the money has been spent, the parts are fitted, and the result at the end are what matters, it should keep him happy for a while..

simon, if your not content with anything about bakes gtr, feel free to line your r31 up anytime you like (or your mates mp3 player) .. until then.. let him enjoy his car stop worrying about what you could have done for him..

;)

Car made 400HP at 4 wheels but was pulled back a bit on final tune to keep everything nice and safe (stock motor) Not running crazy boost either. (only ~1.2/1.3 Bar)

The tune is fantastic, runs so smooth. Tuned for cold start also, Im very happy with it. Ive found no need to give it more than 70% throttle yet either, she goes pretty good ;)

Here is my performance mod list:

* HKS Front pipe, HKS rear pipe with Hi Power Muffler, Hi flow cat

* Garrett 2860R-5 Turbos

* HKS SPL full piping kit with HKS super power flow pods

* Nismo Fuel Pump

* Turbosmart fuel regulator with pressure gauge

* Hypertune Billet fuel rail

* Siemens 610cc Injectors

* OS Giken Cam gears

* Nismo twin plate clutch

* Vipec V44 ECU

* Tech Edge Wideband AFR controller

* HKS EVC6

Tune results at different boost settings on Insight Motorsports Dyno, ALL WHEEL HORSEPOWER: (19 inch volks on)

Now for those interested I had some fun with excel to compare my results from where my car was stock except for exhaust to where the car is now:

Notes: Above dyno graph is in All Wheel Hosepower, the graph below I made is in All Wheel Kw

: Blue line was done on IS Motor Racing Dyno with stock wheels/tyres

: Yellow and red lines are on Insight Motorsports Dyno with 19 inch wheels

My biggest loss in response is ~ the 100Kw mark with a loss of ~550/600 RPM. The -5s catch up ~ the 4400 RPM mark

Would be interesting to do another power run now on the IS Motor Racing Dyno.

    • I used to have Walbro 255's when they were a pretty common update. (or were they 044? 040?) In any case I had a dirty tank. I thought the tank was good, but I would find the filter would clog in maybe ~50km of driving. If the issue persists, well, your fuel system or tank has crap in it that the pump is sucking up.
    • Hi. Ok thanks for the info. I/we do not know what tune is on that Nistune ECU so it is why there is stock ECU and that Nistune is for later when the car is done. I have guy who tunes Nistune and other ECU so i will then take it to him to see and properly tune for the car   And for the update. On 99,9% it is bad fuel pump. Which is wierd cuz it is like 2 years old(brand new walbro 255) and that filter (also brand new) was dirty.  I was alwaya pumped premium(100) on very good petrol station so i dont know how is that possible...  
    • Dear folks My family members have 4 different cars : Triton 2015 and Corolla 2011 and Mazda3 2012 and Hyundai Elantra 2014 Looking to buy engine oil funnel spill free What I found are are below  https://www.amazon.com/gp/aw/d/B0BBTTJNKX?ref=ppx_pt2_mob_b_prod_image&th=1 https://www.ebay.com.au/itm/145553221359?srsltid=AfmBOoqYBU6Ptw0LU_bAp_k67U3qkF97HHvePkA7iHZw8vUmiwoIRaRr https://www.amazon.com/gp/product/B09X23TCS5?th=1 Is there a funnel with attachment that fits most cars ? Don't mind to spend for a decent quality  Thx  
    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here
