still trying to figure out how to post/host a video to the forum. i'll update when I figure it out.
girlfriends cousin owns a shop 45min away from me and just bought a dyno. during the grand opening party they did $100 deal for 3 pulls. it was quick and dirty. nobody tuning. just getting as many people on and off as possible. The shop does general automotive work but does some performance diesel stuff also.
I was the only gas engine vehicle on the dyno for the 2-3 hours I was there, and the only "classic" car...let alone "classic" Volvo. all the modded diesel trucks where putting out between 800 to 1400ft-lbs of TQ. it was fun to turn some heads when the little Volvo's turbo spooled up, and you should have seen this guy in his cowboy boots trying to pull my little car up on the dyno, he stalled it 3 times with everyone watching ha-ha.
I was using 91 octane and was scared of knock and high intake temps, so I used a bottle of VP's "madditive octanium" supposedly good to increase the octane rating of 10gal of gas 8 numbers(I have a 12gal tank). they where nice enough to let me sit passenger and log the pulls.
unfortunately I only got a sheet for my second pull. or at least I was told it was the second pull, max boost in the log for #2 was 17 psi. I question if it wasn't my third pull where the car was running closer to 20psi. i'll get with the owner of the shop and find the other graphs when they have time to confirm.
3rd gear pull from 3500-6500rpm. I don't quite understand it all yet, but I was told they do a 17% correction.
