Sunoco...it made 420awkw at 22psi on BP98...we put the Sunoco in and it went backwards to 390 odd kw. Then i adjusted the timing and leaned it off (Sunoco is a slow burning fuel and likes it lean with lots of timing) and power started to climb again. Then once the correct plugs were fitted it really started to make the power it should have. Then a couple more psi of boost until we saw 450kw (600hp) at the treads.

A more experienced tuner may have gotten more power but considering my limited experience it was as far as i was confident of pushing it without hurting it.

Congrats on the figures, have to be happy with that out of a street registered/driven car :)

Interested to know what plugs you were running and what you changed to see the difference???

Have 2 say a special thanks to paul for all his time in helping me. He knows his shit. As well as glen from esp racing thanx heaps.

Yes its a animal to drive on the road. :happy:

We run vpower plugs

dirt can you post up bp98 tune as well because i want to see comparison of hks t04z with garrett t04z on same fuel

mine made 428rwkw on 24psi (garrett) and another has made 468rwkw on 25psi (garrett). both were standard stroke 2.6l's

is this a 2.6l?

Were they run on the same dyno??

the plugs are NGK v-power coppers

Thats great but you stated "then once the correct plugs were fitted" im assuming you weren't running the v-power plugs at first and just curious as to why???

my hks t04z has gone 585rwhp (440rwkw from my calculation) on 18psi on 98 pump fuel on a very very low reading dyno, another brand new dyno dynamics one i went on recently read 40hp more (520hp to 560hp) on lower boost tune, so i reckon it would of been a bit over 600rwhp on any other dyno.

Dave still had the platinum street plugs he likes to run on pump in the car

platinum + race fuel = ignition breakdown

what sort of afr's do u tune for on race fuel Paul? and how much extra timing is usually able to be added safely ontop of the pump fuel timing? i dont want the timing numbers (unless u want to post them) just wondering how much extra can be added with race fuel?

for fear of being flamed i care not to publicly post what AFR's and timing. Most people fail to understand how this fuel reacts compared to normal pump. You can run it a lot leaner and give it a lot more timing....more than what you would think. But each engine reacts differently to the increase... so there is no hard and fast rule of thumb. Just got to keep an eye on the exhaust temps and listen carefully to the engine.

if i posted the numbers the uneducated would think id lost my mind...lol

no worries, what sort of egt's are the safe limit to go up to? i run 6 egt probes (one in each runner) and wondering what the safe limit is temp wise?

egt probes??

fancy pants :)

we do it by look and feel...lol...those overfuelling backfire flames can be nasty.

So you stick your hand up the exhaust and have a feel, Paul? :)

Nah i was in the car punching the numbers in...i nominated Glen from ESP racing to keep an eye on what was coming out the back. :)

yep, overkill maybe :)

when the last engine was destroyed i decided it was worth it, plus a knock detection setup and datalogger setup for afr's and egt's. The last repair kill was $4000 in parts and machine work, something i dont want happening anytime soon.

i tell you what the egt differences between cylinder is rather interesting, definately something worthwhile for pushing the limits of an engine.

    • What can't be done with a little bit of decking board or similar timber bolted to a hub flange via 2 wheel nuts is not worth talking about.
    • I noticed something. On the tps sensor and the sensor behind the adjustment screw is adjusted towards the far left. Are these screws supposed to be centered? (this sensor was in the same position before the tune as well)  Also attached a photo of where my car usually idles at when warm (sometimes a tiny bit above that). I think I might have screwed up the calculation and it might have better than I thought lol at 750rpm still not 650rpm though.      
    • So for both general interest of engine health, and to rule out any coolant/oil issues, I organised an oil analysis done on the 125,000klm oil Results below, all good, just a bit of fuel dilution which I'm not too worried about
    • This is actually a really good way of measuring what wheels fit. If only there was a similar measurement between hub face and suspension :p That said, it's probably pretty simple to actually measure it all with the wheel off the car for the rear. The front is a bit more complex but.. 
    • Being the top Google search result for R34 wheel-related inquiries, lemme throw down my experience. I calculated that 100mm from hub face to wheel face is about the perfect fitment for my ENR34 sedan.  I've been running 18x8.5s, ET35, with a 1" spacer. So, 8.5in to mm = 216mm. 216/2 = 108mm. 108-35 = 73mm. 73+ 25 (1" to mm) = 98mm.  If you wanna get close to this on dif widths, here are the offsets you'll want: 9" - ET around 15mm 9.5" - ET around 20mm 10" - you're crazy, but ET around 30mm All these should fit perfectly on a non-widebody, non-GTR Skyline. Note that it's probably the absolute max, and you're probably better off running a couple degrees of camber in this config, but it looks great, super flush.
