Ninka Donating Members 1,850 Member For: 22y 10d Gender: Male Location: Perth, WA Posted 24/02/12 01:43 AM Author Share Posted 24/02/12 01:43 AM hey mate how'd you go?Well we are doing some more work on the Dyno on Monday, as my new soft rear Kumho KU31's did not agree with the Dyno rollers, and basically were spinning giving inaccurate readings. What we could see was a discrepancy of up to nearly 800 rpm when comparing engine rpm and actual wheel speed on the dyno, and the tyres were getting VERY warm. We are going to try again with Simon's 'dyno tyres' so hopefully a better result. At the moment I am only running 17psi which gives me something north of 330 rwkw, but not sure exactly what at this stage...... Doesn't feel super fast yet though Engine still sounds terrific though, quiet as a mouse, runs extremely well and pulls better then any I have had before from low rpm, so somethings are going right.

What was the final boost pressure?Spike to about 20 psi, then drops to about 17. Better mid power range as well though.Simon reckons I can't do anymore with the stock turbo, as exhaust back pressure cause slight pinging if we go any higher.

turbowelshy89 Member 147 Member For: 14y 5m 7d Posted 21/03/12 10:03 AM Share Posted 21/03/12 10:03 AM Ninka what oil did you use to run in your new engine. I have been told from a few different ppl a few different things. Like one bloke said to run it in with the same oil as what im going to run it on, then from someone else they reckon to run it in on a "run in oil like penrite". Figure I may as well ask someone who has good results from tried methods. Link to comment Share on other sites More sharing options...
