why dont you have the compressor upgraded to a 20g wheel. The 20g will flow 400whp as long as that turbine can handle it...which is hard to tell. Its a quick spooling turbo so i most likely has a smallish turbine.

 

You may want to get that clutch fixed your results could increase.

 

i think there is a guy in the UK doing this; i'm anxious to see how it turns out

 

To be honest.. if you buy a greddy turbo kit and change things around or try to upgrade to get your high hp goal, than why buy greddy turbo kit at the first place?..

i am taking the greddy the way it is and upgrade at min cost.. hg injector, and my own labor..

if i want 400+ hp i go with gt30 ..

 

im confused; you are saying why would you modify the greddy kit, but you are modifying it?

 

injector is free.. hg is not part of the kit..

 

any reason you do not want to keep it on stock compression? 13psi on a 3mm HG.. isn't that very similar to running 7psi on stock compression in terms of effective boost?

 

Experience What it can do. it only 2mm hg. i stop at 13psi because clutch won't hold anymore, i still end up with more hp and torque.

 

i'll be curious to see what happens at 16psi

fyi, im making a little bit more power than you are, on a dynapack on stock compression, 7.5 lbs, 550cc injectors

 

Well here is the basic map for the Compressor you are working on:



at 13 PSI with a 1 PSI drop across the FMIC, you are looking at a Pressure Ratio of 1.95.

If you are making 13 PSI by 3500 RPM and keep it until 8000 RPM you CFM numbers would look like this - Compressor Map Calcs

Plotting those onto the Map gives you a efficency window of this:



This is assuming everything is perfect your efficency is falling off on the top side to the point you are at roughly 68% (and most like less as this assumes perfect conditions)

Getting more Info and finishing this post up tonight, but I think that attempting 13 psi on this turbo is a bit out of its range. All you would do is generate alot more heat on the top side which would result in a loss of HP where you thought you would have more.
