Hey Mo....thanx for the info...sounds like you have a very nice, strong Vette. Ever had it at the track? What kinda ET's and MPH did u get ? MPH will accurately reflect your weight shifted HP.

So you havent changed the ECU at all - just added a another Hi perf fuel pump and bigger injectors ....and with 10.5:1 comp too ? Hmmm.....

Are you running an air to air intercooler with the water/alcohol injection? I agree, keeping intake temps down is crucial to getting great HP with no detonation. Good to see you have adjustable fuel pressure. I was thinking of running an rising rate fuel press regulator; this will alow fuel pressure to rise as boost rises. The ratios can be altered to suyit your combo. I know some digital aftermarket igns (MSD) will drag timing out of the ignition under full boost/load to as RPM rises to prevent detonation.

Keep in mind that boost gauges dont always paint the accurate picture - engines will show different boost levels in the intake depending on cam design, overlap, heat, intake runner design etc. So 10 psi isnt always 10 psi if you know what i mean.

Hopefully Vortech will come up with something that can be a true bolt on and then can be tweaked from there....

Good luck with your Vette and thanx for the feedback !!
