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???

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.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      By Murray_Calavera · Posted

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
