dont be like that, it was a shake-down meeting and it was well worth it by the sounds of it. although the ET were dissapointing the MPH is encouraging. Its not easy to get a boat to run 11s. I guess you found that the transbrake is a no-no on radials with current suspension set-up. but wont say i told you so.

Its time for 30 psi and the bottle back...... :)

Fixed. :)

I said at the start of the day that with the current tune-up, an 11.xxx would be a success. Job done. Now it's time for 30psi. Bottle later.

yes the boost will definately help but unfortunately the car will never sixty without the bottle.

i though you were building your car to run in a street tyre bracket where you could be somewhat competative, ie no transbrake and radial tyre. you put a slick on that car and you will brake every component in the rear end and be at least 3 seconds slower than your field. i think you may have lost your way somewhat........ :) car ran quiker with standard turbo and manual box on a street tyre.

how much quiker do you think its going to go?

What do you think the transbrake is for? Shopping for real tyres now.

1/ The class you're referring to now allows transbrakes and slick tyres. See www.sportcompact.net.au for details. What's more, they now only run 2 events per year. Not worth building a car solely for that many events.

2/ Slicks will be softer on the drivetrain than radials and you know it.

3/ The car is within hundredths of a second of its PB on its very first meeting out and with a 2.00-sec sixty instead of a 1.6. You do the math and tell me how much quicker it will go by just getting it off the line that quickly.

you dont need to put a slick tyre under that car dude...that would be wrong!

yes the sidewall of the slick will soften the initial shock loading but the lack of tyre slip will see you turning driveline components instead of tyres.

you are a street dragger and reasonably good at it...fu(k Ray Box's stupid new rules..race Andra Super Street and get the car running 11.0 all day. Thats the best option for you that i can see.

At least with Andra you will get a proper track instead of the debacle at last years Compak. The track was a 330' strip as clearly the rest of the track was unprepped. Watch all of Marks vids...the car was 330'ing quicker than its ever gone and then sideways for the rest of the track after he passes the 330 timing boxes.

I love racing on street tyres and the Street Car Superstars event was great but I've always said I'll stick some slicks under it and see what it can do and I reckon it's up to me when I do that. Just a thought.

Isn't the car bogging off the line now? I cannot overpower the tyres in my car on radials...mind you i have twice the grip but also double the power. Why don't you run the car as hard as you can first on the SDR's then maybe think about slicks. You can do what you like with your car honestly i couldn't care if you put wheels on its roof and drove it upside down. Just a thought.

      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?
