I'm trying to collect as many dyno plots as possible of various turbo setups on our cars. Got any, send 'em my way with as much detail as possible on the mods... putting together something pretty cool that I think will be of benefit to all!
Cool project. I'm am so curious as to why certain cars with what should be technically the same mod's respond so differently. I think things such as if you bought the car new and how you broke it in would also help. I'd be interested even in things like oil weight, plugs, mileage and if you dyno'ed what was the weather like that day. Too much detail for you? Should we just toss as much info as possible and let you sort through it? Or keep it simple?
interesting. I think this is going to be ver valuable. If you wnat help compiling, sorting, etc. let me know.
Keeping it simple for now... but feel free to throw in whatever info you have and I'll store it. My main goal is to come up with a comprehensive graph comparing the various types of turbos so that you can clearly see where power comes on, how long it holds etc... but more detail for individual cars would be great. I'm thinking that maybe I can average all VF34 data I get, all VF39, all VF22 etc.. then graph each turbo type average against the others to get a good overview. Should help people select the right turbo; I for one love power but if it doesn't come on until 1000RPM later than stock I doubt I'd put up with it for a daily driver. The graph should also help figure out the area under the curve (maybe I can add that as a separate item) which will tell you how much power you really are getting through the entire band. Me and Genya chatted about this a bit last night and it seemed like a good little project to spend some time on.
Well, honestly, I don't see many people upgrading turbos while retaining stock uppipe/downpipe. So as long as a UP/DP TD04 plot is in there, that should be a non-issue.
I'll try and scan my dynochart tonight after work. I have a TD04 with UP/Stromung DP/and when it was Dyno'd I had a STi catback. 208 torque 212 hp. peak torque at 3000 rpm, tapering off at 6000 rpm. I believe max hp was at 6000 rpm where it then tapered off. My question is, does that mean that I lose my boost at 6000 rpm, so that would be the best time to shift? Craig
