What dyno graph are you looking at?

At 2500rpm it's only making 130hp atw

G.J meant there was a power band of 2.5k where its making in excess of 500hp ie from 5000rpm to 7500rpm

Your obviously not reading it right because at 2500rpm its making more like 70hp not 130hp.

yeah and what I meant was the power band is narrow because there is no point using that last 1500 rpm.. power goes DOWN, markedly.

So you need to change gears at 6000, otherwise you lose.. the rest of that plot is a waste of paper. A tuned rb26 you can change pretty

much at redline, the drop off is so mild and only the last 400rpm.

sure it does 500hp from 5000 rpm ... but only for 1000 rpm of usable revs!

Quoting Mr.Alex

Hi Guys!

Thoght i'd share my big block evo experience with you.

Got the engine tuned and dynoed 2 months ago, been to the track for 2 days and the only thing I can say is that this is one crazy engine, all that tourque is just amazing on the track, pulls so hard after 3500rpms that i barely ever go below 4th gear.

i dont know if the scale on the dyno chart is correct cause the car is a beast after just 3500rpms, pulls just so hard i can hear my seats crack

Its a build from a local tuning shop here in Sweden, Autotech as said in the sheet :D They know their stuff, had time to to talk somewhat with em when a friend of mine mapped his Autronic controlled WRX STI on ethanol. Had this one in at the time.. gives you the creeps.... Got a couple of Evo's around here with 'big' hp's, many of them mapped at Autotech :bunny:

      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?
