I think Markski is doing a fun experiment as well. Put GT3 heads on a turbo block with upgraded rods and pistons. You will have great RPM range, and due to the higher revs you won't need as much boost to attain a particular HP goal. The N/A GT3 makes 400HP as is.
The higher redline will negate needing to regear as each gear will go 23% faster.
IMO that would be very fun car indeed. Ferrari RPM levels (or GT3) and turbo torque and HP.

I think you are definately plowing new dirt and we will all learn form your and others endeavors. Thanks for sharing and good luck. Ps what would you guess your car was capable of running the 1/4 in even soft launching it? Sounds like 10 flat or maybe high 9 to me. Anyway keep the tip owners proud my brutha! Later.

Im keeping my fingers crossed.
CJV helped alot in parts....
like the cams and cam housings....markski

The OEM MAF has a voltage that runs through it in a direct relation to the airflow that passes over it. It is this variation in voltage by which the MAF reads the amount of air coming into the engine. When about 550-600 HP, it is also at it's maximum voltage capacity. Air flow increases above this level are not registered by the MAF. Said another wat, the OEM MAF has very poor resolution in the upper HP range. Some tuners use a MAF that can handle a much higher voltage and hence the engine can be tuned better in the higher HP ranges. I believe Protomotive use this approach. Other tuners use a larger diameter MAF tube, in conjunction with the OEM MAF. The larger MAF tube mean less air flow at the same HP as a norrower diameter tube. With this approach, you can get better resolution in your tuning in the high HP ranges. I believe UMW and Sportec use this approach.
If pushed too far, the voltage increase running through the MAF can cause it to "pop". Strangly, some cars experience this much more than others. I, unfortunately, have a MAF eater. With the added air flow of the having a V-Flow installed, I can blow a MAF in 20 mins. With the OEM air box installed, the MAFs seem to stay alive.
As was posted by Mike at EVO, several months ago, EVO are working on a MAF solution for the GT700+ cars. As to thier progress, I haven't heard.
