On standard N\A what is the maximum RPM you could reach?? Mine stop at 6.300 rpm with dbilas intake, full custom free flow exhaust, 266°cams and 68mm TB,probably i could reach 100 more rpm without the rear wing(medium tilted) but no more.

Haven't had a long enough runway to try? Muncher has done a Vmax sprint in his Stage2, so he may be able to suggest a figure.

To be perfectly honest I can't remember what I got to, I don't think it went past 6k though and that was over approx 2 miles. That gave 139mph laser verified with a passenger. Without a passenger and with the hardtop on I'm pretty confident it would do 142/143 at the same venue.

Hi cicastol, can't help on the RPM but..... I reckon you now need to get a performance head to increase airflow from the dbilas into the combustion chambers I think that will be my next step. The standard head appears to be somewhat of a bottleneck!

I ordered the 68mm TB Saturday night

My speedo gave me near 230km\h (142mph) at 6300RPM there's something strange if you could reach 139mph below 6000rpm!

Sure this will be my next step for next winter time mods!!

Congrat. for your's TB!!

Hi, as far as I know max. RPM in 5th is 6250 RPM and 6400 RPM in 1,2,3,4th gear (standard software). Not sure about reverse gear

completely standard NA i was getting speeds up to 241km/h (each day when going on that road). On the speedo that is and downhill a bit... When i switched to fatter fronts (16") i didn't reach that sort of speed again.

My standard Speedster did max out at exactly 220 km/h on the Autobahn. My speedo is reading 100% accurately according to my GPS. I did not take note of the rpm, but you can calculate that with a gearing spreadsheet in excel or similar.
