Nice work... 175kw is a truckload. Must be a good 150-160 at the treads.
Should do 11 or 12's now...
What did that goldcoast DC5R run on the 150-something kw output?
My car made 153 fwkw on toda dyno and made 145fwkw at Brisbane AutoSalon with a std bottom end k20 and toda spec C head. The best i managed to run down the 1/4 mile was 13.9 @104mph and this was spinning 1st, 2nd, 3rd. Car used to do 150kph in 3rd @ 9000rpm and 190 in 4th @ 9000rpm.
You need to get yourself a RBC intake manifold from the states and a 70mm BDL throttle body as well as a 3" exhaust, you should be making 175kw at the wheels with a full engine build. Your current intake manifold and exhast is very restrictive. Also if you do this you will need bigger injectors to feed it enough fuel.
Congrats on the build sounds like your very happy with it.
153kw at the wheel, and you did a 13.9sec...you're kidding...does your car weigh 1.4tonne???? or you missed 2 gears????
hmm..the 3 inch exhaust, u mean the tip or the piping size???
You really mustn't know much about 1/4 mile racing otherwise you would have realised that my trap speed of 104mph suggests that the car is capable of a much better time (flat 13 possibly high 12), and as someone else mentioned my times were done on street tyres spinning 1st, 2nd, 3rd gear.
The car was built for circuit racing not 1/4 mile, last time i went to the circuit i was doing the same times as GT3's and a 500hp R34 GTR, dont believe me then go to http://queenslandraceway.com.au/ then go to calendar and click on sprint results, then once the excel sheet opens click on the Wednesday Sprints tab at the bottom, name is Anthony Goulding.
Exhaust i mean a full 3 inch system from headers back. 2.5inch has been proven to be too small for a k20 with big cams and even JDM k20 with I/H/E/K-pro. Problem with a 3" exhaust is that its gonna be f'ing loud.
