and the RESULTS of 17.5PSI I must say I am happy with the results just wish I could use the other 8PSI that are on the table.

431 HP and 441 Torque (by GTECH PRO)

Long time no update... last time I took it for a drive it was absolutely ridiculous amount of torque available instantly actually 0-18PSI in less then 0.89 second below 3000rpm with a little more then 1/4 pedal travel I almost bent my passenger rear wheel hiting the sidewalk...It was a lot of fun... but I let go the pedal instantly as I fear boost is more like 23PSI+ total and that is too much boost for my stockish motor at this point. I had miscalculated the amount of total boost multiplied compressed boost looks like this

On my twincharged setup I have 8PSI from turbo and 10 PSI from my Roots supercharger giving me total of over 23PSI..

So I had to find a solution I research the web on how I could limit the amount of boost (at this point I already tried a bigger pulley spinning the Supercharger slower but still too much boost) Plus I enjoyed the quick torque of the charger with more boost. So I found a BLV (boost limiter valve) made my 928 motorsport its a beautiful quality valve made easy to adjust from 0-30PSI. I adjusted mine to 17 PSI.

So I welded the Bung that came with it and used JBweld high temp on top of my welding to make sure to block any pin holes.

Car is now COMPLETED :) all I am missing is tuning a little more part throttle and WOT on the street and its Dyno time for spark tuning, numbers and drag racing time oh and videos of course...lol...

Here it is twincharged M20 fully completed.

M30 sitting patiently for my soon to be next project...in 2 months as soon as I finish parting out my parts car.

Interior pic all business...

front shot.....needs a clean and polish! but it will have to wait until tuning is finished.

Stay tuned ....
