Ohhh interesting stuff on the cam Karlos, i read t28* and just made the rest up lol,

my turbo is pretty fucked and i don't think the bodgetastic bleed valve is helping things but your graph did look nice pulling to the top.

Why is that Chip, surely Robs engine will be much more responsive than mine (going by the graph shape)?
Or just because of how it spikes and then drops dramatically?
To be honest the car drives/drove very nicely like that ignoring the high rpm torque drop off (which i think is due to knackered parts) i think looking at the two graphs if you weren't full throttle etcetc at high rpm the higher comp engine would actually drive better around town, ie @ 2800rpm high cr was making 65bhp and 125ft.lbs where as low comp even with mild cam was only making 50bhp and 100ft.lbs and @ 3200 high cr is 80bho 135 ft.lbs compared with 110ft.lbs and 70bhp.....

A nice graph would actually be karlos's top end and my bottom end, especially if it didn't have the t285t2 fitted, @ karlos i think it hit full boost rather quickly (even with the 2wd turbo) like at 35-3800 rpm however the spike was massive and the drop off quick lol, also i think totd quoted max boost at the spike which i don't really understand?

Point being that with the correctly speced and non knackered components high comp really is worth it, and more to the point karlos's new engine with standard compression should be something rather nice. Jambo your graph looks quality, but i cant help thinking max boost would be reached earlier and power/torque would look better with a higher compression ratio.

Rob,
