Contour Enthusiasts Group Archives Forums General Dyno and Drag New dyno numbers on 8 psi

I don't know why it is doing that to me, but I went to cardomain and found it.
Pretty smooth curve. Nice power. I am still very curious as to what will happen with those huge ported 3L heads and the stock contour cams. I'm betting your peak torque will be out of this world as 15 psi but your peak numbers are going to suffer.
I don't understand why the small exhaust housing on the turbo when you are alreay running 1mm overbore? Technically your engine is bigger than mine and at the same boost pressure you should have more air in there than I do yet you are really just generating very similar power. Like Demon said, you will really see some gains at higher boost levels though I would wonder when the turbo will run out of steam? Probably enough breath in that thing to pull you 400 wHP though.

That rapid torque spike is probably the result of the quick spool on the ball bearing turbo with the smaller housing. Mine spools slower becaue it isn't ball bearing and it has a larger housing but it matches up well with my desired powerband.

I like it. I can't wait to see what it will be like at 14psi. Why don't you just turn up the boost now? Once the MAF is dialed in the pcm will keep things pretty tight as far as the air fuel is concerned.

Great job man!
