DR's and launching around 5,500 hundred works for me. I got better times leaving the hole in VVL than say 3,500-4,000. I've had over a dozen passes down the track with the VE and found that to be the best for mine.
Interesting Fidanza flywheel is listed as 8.5lb (assuming you are referring to a Fidanza) for everyone selling.
I saw on Fidanza's website - application guide section - that it's actually 9.9lbs. No mention of a 8.5lbs flywheel for fwd sr20. Contacted the seller of the one I am buying and he said it was a typo and it's actually 9.9. lol
My friend told me he weighed his and it's 8.5. I will surely weigh mine when I get this week.
Now I normally launch @ 3000rpm with sr16ve (16.25lbs) with sr20ve. Thinking of 3700-4000 with the flywheel and launch control.
But not sure how that will work on the 1320 as I will not be able to warn 50 thread wear tyres @ 4000rpm
Peace
I bought my Fidanza flywheel it was late 05 or early 06 and I remember at the time they had 2 flywheels listed at the time. I never put mine on a scale when I got it since it was lighter than my stock and SR16 flywheel I had lol.
