Just buy a heap of G size bottles... and while the import cars are running, open all the bottles into the dyno cell - extra power and a nice relaxed and cheerful mood for everyone :D It might cause a fire, but that just makes it easier to cook the BBQ food.

Ken/PIMPED, 400rwkw using 550cc Sard injectors... that's what i call pushing the limit!

I'm going to do my best to make it to this dyno day, as it sounds really interesting. It'll also be interesting to do a rough comparison (power curve, peak values, turbo response etc.) with my own dyno runs on Shaun's dyno - there's about 90+ of them saved on the thing ha-ha.

I might even have the tuning finished by then and could try and help bolster the import figures - I 'may' be able to offer low 300's at the rears - best of 302rwkw so far. It might squeeze out 315-320ish once the cams are set-up and a few more pounds wound in.

What we - the import team - really needs is for Darren's R31 to be up and running - 550rwkw would help push the total up nicely.

yeah im abit worried bout that atm, going to 1000cc soon, but i hope the 550cc will hold out for 400, fingers crossed anyway, but it makes 300 with easy, fuel is running really rich atm, was told rich enough to get almost 400rwkws with but i would be pushing it, i dunno, ill get it on the dyno and see what we can do, and the remap of the 32 ecu is wicked, better then my power fc in my old 33

Nitrous oxide is not flammable.

Correct. Oxygen is nonflammable too. However, what these gases are very good at is supporting explosive combustion, all they need is an ignition source and a saturated concentration - think dyno cell full of G size bottles opened fully and then add a red hot manifold. I'll be the one standing over the road :P

Next time you're at the drags and you see someone purge their nitrous system, don't stick your head near the stream of purged N20 smoking a cigar... unless you want to look like Micheal Jackson :O

I guess it depends on how 'real' those 400rwkw are, if you get my drift. To safely support a genuine 400rwkw you are going to to be pushing well beyond the safe level for 550cc injectors. I wouldn't risk it. Wait till you get the 1000's in.

just grab some NOS and spray it into the intercooler MRVLT style.

hahah yeah that was the funniest thing to see on the autosalon dyno

they could have just used fire extinguisher

it would have done the same job lol

even funnier the power figures didnt really improve though lol

Using LOX (liquid oxygen) would 'kind of' work nicely at externally snap cooling the intercooler :)

I can't recall the exact LOX temp off the top of my head (- a few hundred 'c) cryogenic freezing temp's that's for sure. It also has an expansion rate of 600ish to 1, as in 1L of LOX = 600L of gaseous oxygen. So watchout when it reaches a source of ignition! Great for speeding up the BBQ cooking times, it'll cook snags in microseconds, then melt the BBQ and burn a nice hole in the ground under it :)

Anyway, back to the dyno day conversation. Any info' on the domestic entries?

hey buddy who did u get to remap your 32 ecu??

jeff at turbotune, did a good job, isnt cheap for most people though, lol, also i wont be boosting her up anymore, keep her at 300rwkws, 550s wont hold out, it will lean out to much, 20 psi is pushing it with them, so 16 psi will have to do, will still be in the 300rwkw club though, if there is such a thing? lol, hope to see u all there

Good move mate, as it's just not worth taking the risk. Get those bigger squirters in there first, then you can crank up the boost safe in the knowledge the fuel system can support it.

We are both at a similar point actually, as I'm just about to upgrade to a new set of 780cc injectors in my 33 - my 550's are no longer up to the task... especially for E85.

so urhhhhh what are you going to be doing with the 550cc injector? :O

Ha-ha, yep, I'll be selling them. However, one potential problem. I have a custom top-feed fuel rail, which means my 550's won't suit the OEM RB25DET rail.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
