2012 Gt-R Goes 10.67....

[GT-R OZ]

Why spend 20k++ on mods when this is all you need!

Another great package here too!

SBD700 Package: The Ultimate Pump Gas/E85 Stock Turbo package! $4095 (10.5 @131 MPH)

it's well known cars in US (even Japan) are always a good .3 -.5 sec quicker down the strip compared to what you can achieve on aussie soil - like for like

i think the main reason is the way they measure roll out, which on a hard launched awd car is a noticeable time advantage

Martin's 10.3 for eg would be close to a 10 flat on a US drag strip

a more accurate comparison when looking at acceleration times from different countries is the 60-130mph

The point I was making is value for money you get over in the US for the horsepower gains you receive. I agree the 1/4 mile times seem to be measured differently.

Seems pretty good value IMO. Of course stockies like me would need to fork out another US$1295 for the Cobb AP + TCM on top of the base price.

re value, it's to be expected price of parts will start creeping lower given the tuning scene is now 4+ years old - you won't see similar savings from jdm parts though

Its easy to make big power out of these stock engines. The trick is to keep the stock rods inside the engine over the vehicles life......

Getting a one-off drag number isnt so hard if you put your mind to it. It certainly impresses a lot that dont understand the risks, and the massive potential cost, involved

[GT-R OZ]

Why you would spend 10's of thousands of dollars on modifications for an extra 0.1 to 0.3 of a second over a 1/4 mile is beyond me. Especially with these kind of results with just a mid pipe and tune. A good video this one, some nice shots taken from inside and outside the car.

power gains vs costs is a law of diminishing returns, no one is forcing you to play the game

That's exactly right. People who spend that kind of money to get such a miniscule increase in performance (which they would hardly ever use anyway) don't do it because it actually makes any sense, they simply do it because they can!

Some NHRA tracks have advantages over WSID, Willowbank, Kwinana, et al. Soem of our Big Dogs would run PBs at Atco or E-town fer sure.

[domino_z]

the difference bw 1st and 4th at the last 1km event was a pair of mod'd turbos

you may call it miniscule, others call it....

Lol don't know if the owner of that AMS Alpha 12 would agree with you. Didn't win and couldn't even crack 300kph! Money well spent?

[domino_z]

wrong event..... but, traction issues

[maxzugkraft]

Sorry off-topic.

Hey Domino, how did you install your rear diffuser fins? Did you have to drill the carbon panel under the car?

I like the look and should reduce soot on the back of the car. Did you find any difference?

Thanks.

[domino_z]

i get absolutely zero soot daily driving on e85, that's the best solution to reducing carbon emissions..... or Martin should have the new injector end pulse tables for cobb which may help on 98 Ron

im not sure what part you're referring too

I am running the top racing carbon lower diffuser which replaces the oem part

These are the hks kansai diffuser fins I bought a while ago. I haven't installed them yet, looks like you have to drill into the oem carbon diffuser. I had to paint the leading edge on both pieces matte black as they were quite rough looking with excess resin

but i can't see how either part could possibly reduce soot

Just to put this topic into perspective.....WR450 package, which is exhaust, pumps, injectors, E85 tune on a 2009 using the old LC2....

Running 10s on an E85 tune with stock turbos isnt exactly new, that was 2010.

[TOMMI MAKINEN]

^ Whoop-dee-do!

What would that cost the average consumer... just to put things into perspective.

[maxzugkraft]

Hey Dom -

Yup, that's the one - the Kansai diffuser fins. I thought you had installed that (saw your NAGTROC post).

Apart from the the good looks, the diffuser fins should extend the turbulent wake further behind the car at high speed, therefore reducing accumulation of exhaust output onto the rear face of the car. It should therefore reduce drag and improve rear downforce in conjunction with the rear upper spoiler.

Around $5K all up is what most GTR retailers will sell this kind of package for depending on existing mods already in place (ie. exhaust etc). and what brand parts they use. Not bad for a daily driven 10 second car

Many different kits from many different parts upgrade manufacturers to do this on these great cars. GTRs are a great base, which is why we all like them so much here.

[GT-R OZ]

Plus another 8k to ensure the transmission remains compliant. Or have we forgotten about that?
