just got back. good god!!!!!!! first pull at low boost was very impresive. up top we ended up maxing out the turbo so we couldn't even get back to the same boost level we had before the cam swap so it isn't all that great of a test but at the pump gas level it is a great before and after test. the change is hardly believeable.

Good Deal Parish, Looks like i found my next Mod......

set up. mp70 turbo, stock 5.3 other than springs, t400 with an overly loose converter.
first chart is a real good before and after test of a stock 5.3(blue) cam vs a 2001 zo6 cam(red). minimal variances, the numbers prety much speak for them selves. WOW!!! this is our max pump gas setting
next chart isn't the greatest comparison but you definately get the idea. we ran out of turbo so we couldn't get to the same boost level. you can see we are up 48peek hp even though we are down almost 4psi. does this seem insane to anyone cause it doesn't seem possible to me. at 6100rpm we are up 87hp even though we are down 5psi
last chart is us maxing out the turbo. there is a funny story here. we had a 6psi spring in the wg and though it might just be out of spring so we swaped in a 13psi spring. we forgot to hook up the boost refrence line to the wg
, the thing should have hit 30+psi but it didn't go up at all from what we were seeing with the 6psi wg spring and the boost controler at 100%.
you can see where the boost went up some. the exhaust back presure went way up. even with quite a bit more boost we only made a few more hp. the iat's were going up quickly too. the wg was esentialy blocked off.
we are not going to run it at this maxed out setting since it is only gaining us a few hp. probably run it at a max of 15 or 16psi. right now we are likely near the limit of a pile of other things on the car so steping up to a better turbo to get more power doesn't make much sence. now iguess it is time to get this power to the ground
