Thanks @evilhighway! This is why I love forums over social media, Things stay where they are and doesn’t get washed out, people can come back whenever for a read if they need a reference for anything. And also it’s also more formal~ish and I like that haha.
Months has come past and i’ve taken the car to Sydney Dragway for baselines.
With the HKS Intake and custom exhaust (with cat) My PB is 17.1 @ 78MPH.
She’s nothing quick but quick enough to surprise a whole crowd of people for staying door to door with a XT BA Falcon LPG hahaha. Most fun drag race i’ve ever had. David vs. Goliath
But again found out a few little things that I could improve on.
Heat soak being the biggest thing I noticed. The more and more runs I get, the slower my times got and wondered why.
Then someone brought up heat soak. The intercooler was pretty hot to the touch so we squirted some water on it to help it cool down a bit faster before the next run and it worked! My times had gone down to around 17.2xx from 17.4xx when hot. It’s still an issue I need to resolve, just haven’t thought of a way to work it out without making the charge pipes 3ft longer haha.
Second thing was not having enough revs. Yes, 8000 is not enough hahaha
Why? Because a few metres just before I pass the gates, I had to shift from 3rd-4th. But that takes time and have another maybe 0.5 seconds to build up full boost. Therefore affects the ET.
Luckily someone local was about to sell his Copen and he had a D-Sport ECU in it, As soon as I found out he was going to sell his car, I straight away messaged him about parting out a couple of parts, one being the ECU. The next day and a few $$$$ later, I’m a proud owner of a D-Sport ECU hahaha.
This meant 9000 rpm, Higher Boost Cut and adjusted Fuel and Timing for higher boost levels and up higher in the rev range. (so I’ve read, don’t count me on that haha )
