The Skyline has won the most prestigious award yesterday at Santa Pod Raceway yesterday.
The Japshow trophy brought all the top Japanese Car tuners in UK to compete in this year's final run. Intense qualifying rounds and elimination has caused a few fatalities. Brief list of line-up includes the famous Norris's awesome Evo, Alaskan's "Roger Clark tuned" Subaru, Supras and Skylines. The final honour went to Gary Passingham's skyline who made impecable progress durng the day. His quarter-mile time recorded on the day was 10.7s, 10.5s, 10.22s, 10.078s and finally beating Roger Clark's Nitrous equipped Scooby by 1/400th of a second, clocked at 10.20s. Here is a couple of pictures to celabrate his momentous win against all the top Japcar tuners in UK. We will continue to help devloping this car on the water injection front. Just to confirm the a/f ratio we were running was 12:1afr/33 deg. advance.

After four hours of sleep (they all live 40 minutes drive away from home), they were back at the workshop at 5.30am and loaded the car onto a trailer and set off to Santapod raceway- 3 hours drive. Only to find out the road to the venue has an one mile long tail-back and took nearly over another hour before entering the gound. One of the them has to drive another skyline to the raceway on their customer requested - imagine dring a car with a straight cut dog box for four hours! I am soy please for them that tou came home with a well deserved trophy. I was lucky, only ten minutes from home, so I got a good five hours sleep. One other good news, their non-pro class customer has also fullfilled his dream on hitting 10s (10.99s) on his well-under powered skyine :razz: :razz: :razz: Three 10 second skylines made the show and drove home without any breakage on the day.

"Three 10 second skylines made the show and drove home without any breakage on the day."
Even more impressive. Must be nice working with some good mechs and racers. I like the bleeding edge and winning just like everybody else...but I also like not breaking things and can understand how much money and effort it takes to try and prevent that. I know these guys must be exhausted....but it seems like theres been a really nice pay off for that work. Again, very nice, I salute you guys. |

Those guy arrived back home at 11pm, got a bit lost on the return journey but back at work at dawn - I didn't think the adrenalin level has quite subsided. Richard

We looked back the dyno plot back in April and the same race fuel only managed 704whp. The car was hovering around mid 10s then. It could have easily gone into the 9s yesterday if the driver was not under pressure in the race condition against another car. I have made a mistake on the heading of claiming 790whp - will correct very soon. Here is the latest power figures we achieved with about 10-15% of water/methanol. Pump fuel (98 ron) only .... 610whp Pump fuel (98 ron) + ~WAI ... 643whp Race fuel (106) only... 704whp Race fuel (106) + ~WAI ... 760whp EGT was kept between 880-890 degC Will be increasing the w/a/f percentage continue to extract more power in the coming months - race season is now over. We will continue around 50/50 but push up the ratio against fuel. I would like to see the w/f ratio going up to 40%. Richard

I saw that car at the Pod, so it was the one used for the precomp nozzle prototypes, eh? :smile:
As for the W/A/F ratio, I've got a SAE paper claiming increasing gains at an excess of 100% :wink: (might be useful for fire-engines rushing to the scene of a fire, lol....) |

According to SAE, we should be able to reach 1500 at the wheels :razz: The turbos were only rated at 380hp each (at the crank), I think the WI has extended its output beyond 760hp since it made that at the wheels. I will scan the the "night before" power graph and post it here.
