You can see how long a gear change takes on the graph from the data logger, and starting in 2nd and crawling along at 30-40mph on a nice dry level road you'd be hard pressed to spin the wheels, unless you have monster torque!
I've just done a run, with the new turbos fitted, but not mapped yet so boost is down at 1.0bar. You can see my run isn't smooth so maybe the ECU is pulling timing a bit? I just thought i'd see where it is, 7.34 seconds is certainly in the right direction
I think when i get my RS Tuning map and it's boosting properly, it should be touching 7 seconds. That will be with around 520 flywheel HP, which is around 450 at the wheels?
Back to the 1.0 bar by 2600 rpm on a CIS car with 400HP at the wheels.......
This is a graph with my 930 when it was running a small Garret ball-bearing turbo, it is showing flywheel HP so maybe 350HP at the wheels. My engine at the time had 964 cams, ported and flowed heads, headers, tapered injector blocks to match the ports blah blah.... I'm not sure what model Garret turbo it was, maybe a GT30r, it spooled REALLY quick.
What turbo are you using to get to 1.0bar that much earlier than this, AND make a HUGE amount more power???? I may be an antagonistic pain in the arse, but I call BS
