Had a good night with no issues.
Ran the car on 17psi until I got beaten by a barra. Then I just went to map 3 30psi for the night. Antilag works really well but the timi g would never recover until 2nd gear. It would be on 0 degrees until I shifted. Thr rest of the night I just launched without antilag. Tyres were dropped pretty low at 25psi. They did not spin at 17psi antilag, no spinning or chirping it just hooked. Lost to 3 cars during the night. First was unknown barra, but i had 0 timing in 1st gear and in 2nd I was gaining very quick but didnt catch him. 2nd car was 1000hp or maybe 1200hp supra manual. I was ahead after the launch for 50m then he got in 3rd gear and just took off. 3rd car 900hp lsx turbo vu ute t400 I got out first then he slowly went past and beat me 2 car lengths. There was 4 or 5 cars that were faster at the event but I didnt get to race them all. Car went really well. Having grip really helped as no other cars had a chance for the first 50m even the 100hp ones. It was so easy to just hold it flat and just bang up a gear knowing it would just work every run. Really happy with the racing and how my car went. There was a fair few having a look at my car when I was in the pits wondering why it was quick and so quite. Next step is taking turbo kit off and making a single scroll manifold and 4 inch exhaust for 7675 turbo. |

Congrats mate. Sounds like the car is running great and putting down the power. More in it with timing etc to iron out. Awesome to see it out on the strip after missing so many. You must be smiling |

The drag strip wont be used this year. Nothing to do with rona.
All they care about is getting 1 top fuel round up here each year. Its cancelled due to rona but they wont put on a local meet. Closest track is Alice Springs. |

You should call the complex management and see if they can run a Test N Tune to see what interest they get.

Its pretty hard launching with a small turbo. it just spins if you put the throttle down to early on the street.
Its only taking around 14psi before it spins in the first 20m or so. |

The g forces at the track were much higher when taking off from 40km then what I have had on the street so 60ft will go down. How low depends on the tyre really.

No more mucking around.
4 inch dump pipe and 2 inch wastegate. Might cut the exhaust a little bit. Last edited by Brule; 09-28-2020 at 12:32 AM.. Reason: Add video |

Tried to go fast today.
Pb et and mph but still in the 12s lol. Sorta not funny I want to go faster but that was it after 3 goes. other runs were 12.1 12.3 at 125 and 126 with boost under target. Accidentally warmed the tires up so they were ready but its just hard to hook on non drag strip places... 1/4 12.02 @128mph. 1/8 8.11 @ 97mph The front half was slower then my pb on 17psi but obviously made up a bit in the back half with 26psi of boost. pb 1/8th is 7.71 @84mph with 5.07 330ft and 3.75 0-60mph at let iff early like real early. Todays run..pb but I want faster obviously. |
