a decent guesstimate using the coversion from g/s to lb/min and the 10 HP/lb/min generalization at peak power

100 g/s = 130 FLYWHEEL HP

That's assuming an unmolested MAF, it's been VERY accurate for me.

So in theory, you should be able to accurately fuel up to 660 or so FWHP.
Thanks for the info, I was also guessing 550RWHP.

So where do you get these metal MAFs you are referring to? Are they from older ls1s or aftermarket.

PSJ, are there any links on the net about the TCI solution. I sent an email to Mack to see what he has on it.

I forget the link to TCI's website, it was not that great.

The metal MAF's are just normal MAF's (as opposed to the 6.0l/Z06 variants). The "metal" refers to the MAF ends, not the electronic portions.

ECU reads frequency readings from the MAF and not 0.0 to 5.0 volts (like in the Mustang) ?
