Would be nice to see any of the graphs....

My VTEC engages at 6.5K, tuned by Performance Autoworks.BMCC wrote:@ Merlin is your vtec change over higher approx 5800rpm?
Yup. We didn't get them printed either. They sent the lot to my email.wurlycorner wrote:Is that the print outs they gave you, scanned in?
They look like screen dumps from the live monitor, rather than pukka printed calculated graphs?
Sure but at 6.5K when VTEC engages you get zero benefit.The graph from 6.5K to 8K gains practically nothing (BHP). I've read the other page and the torque part is noted but at least on the other graphs they get some BHP increase when VTEC comes on. The gradient of the graph changes showing a quicker rate of increase in power gain for all but yours when VTEC's on song. If your happy with that then fair enough, me I'd want to know why VTEC does the best part of bugger all.Merlin wrote:BMCC - Remember my engine has been built and tuned to specifically not have a huge jump in torque. I get more torque at 3K than a stock H22 gets at peak torque. The torque dropping off is the issue I have been going on about with these dyno results. You can see torque dropping off just after VTEC in all the dyno graphs posted in this thread. Read the previous page.
