[QUOTE=zildjian4life218]it was discussed earlier in the thread i think right around 200hp but that was at 7psi[/QUOTE
If that is correct, then you should be able to push 250 each out of them. Most manufacturors design a margin of error and try to keep the turbo in the safe range of the compressor. However, you can usually safely get more. The only way you will know for sure is to find out exactly what they are and get a compressor and turbine map for them. To discuss without those things is pure speculation.
