I headed down to AIR tonight (06Dec) to lend a hand to Shaun, Ben & co as they were running the 'Boost Worx' backed yellow 2JZGTE powered Supra (ex-RPM car).

Ben ran a string of low 11's @ over 127mph before finally getting the car to run closer to its potential with a PB of 10.8 @ 125+. The mph was down on the earlier passes as an IC hose blew off going into 3rd gear. The car should run closer to 10.4 with a few more tweaks.

All passes were on ET Streets (DOT approved) I'm not sure if they qualify for the HPI Street Drag Challenge or not?

I'm sure most will agree that the 2JZGTE is an awesome engine. Ben's Supra runs a dead stock internals 2JZ.

Another car worth mentioning was the factory standard new 3.5L V6 Magna (base model) whose female driver ran back to back 14.8 - 14.7 mid 90mph passes (best of 14.7 @ 96mph). The only mod was a slight change to the air box feed.

Yeah mate sure have!

I remember reading articles on the MKIV JZA80 Supra when it was first released in Japan. It was my #1 choice when I got interested in imports back in the early-mid 90's. They were a touch too expensive back then though :) Hence I got the Skyline instead. I've gone too far with the GTS to start again now :)

Hip,

Brand new ET Streets & a good suspension aligning session made a huge improvement on the strip.

ET Streets are a drag radial tyre made by Mickey Thompson. They're DOT approved which technically makes them street legal.

"There's a simple way of identifying whether or not a tyre is legal for road use. If it has "DOT" or "E" written on the sidewall, it's passable - no probs. DOT is the US abbreviation for the Department of Transport, while "E" is the recognised European compliance symbol. Having said that, it wouldn't be unthinkable to get pulled over by the police for supposedly "bald tyres" - regardless of their technical legality."

The car is with Boost Worx now as the mechanic linked with the car moved from RPM to set up his own workshop. So the car moved with him.

Tim,

I'd say traction would've been a huge factor in who hosed who on the street! Neither cars have/had a lot of traction on road rubber. Ben mentioned turning the tyres @ 180+ on the road.

      Its also worth mentioning that 30 years after it left the factory and god knows how many missed oil changes since, there is every possibility that one or more lifters are ticking because they are sticky/gummed up. To resolve that you need to pull the cams then pull each lifter, disassemble, clean, reassemble, soak in oil and re-install, and they should come up good as new.

      What air filter are you running? Is it a panel filter in the stock air box, or a pod filter? Is the air filter the type that is oiled?   If you unplug the IACV, what rpm does the engine idle at?

      Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.

      This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.
