I'm hoping to build this as a data-base guide for reference for all of us to reference in the future. I searched but didn't find a thread like this one, so here goes.
Please list what turbo you're running along with the amount of boost and HP #'s you're getting. Also and probably most importantly, tell me by what RPM you reach full boost when starting from a very low RPM in 2nd and 3rd gear I want to base it from a gear that doesn't load the engine too much as we all know it's easy to build a lot of oost in 5th at an early RPM.
Also your cam setup would be helpfull for this as well, as i know it effects spool times.
Here's mine as an example ( in my current configuration, not my previous motor that made the 468/429 which is in my basement waiting to get the main journals re-sized)
T3/T4 hybrid (non ball bearing) - To4E cold housing, 57 trim wheel, .62 AR hot side with a stage III turbine..stock 1g cams
Starting from 2500 RPM in 2nd gear i reach 18 lbs by 4600 RPM then the tires explode into massive wheel spin ( 4200 RPM in third and the RPM point gets lower with each progresively higher gear due to load)
~ Aprox 340-350 HP on 91 octane, depending on ambient temperature and timing curve @ 18 PSI
I'm hoping that with this database, people will be able to pick a turbo that suits their needs as closely as possible. Much like i'm hoping to use this for...Compressor Maps and theory are one thing, real world experience is another and that's what i'm wanting to base off of.
