This is a car we did a year or so ago and it made 1022. Just changed from a ported LS7 to a MAST LS7. Car now carries the power all the way to 7k when before it fell off hard at 6100 or so. Look at the diff at 6800rpm... Over 300rwhp and trq

Car made 1073hp and 1030 trq

Here is the graph from before with the X-pipe open to now with the new heads and Boost activated cutouts.

Is that just due to the different heads?

LS7 BUD

How much better are the LS7 mast heads compared to a fully ported set of LS7 heads?

Good numbers and all, but question to farther my knowledge. What happened between 3,200-4,500? Specifically at 4,00, it appears to be a loss of 100+ hp? Is that intentional? It carries the power out really well on that graph. I don't mean to be "bashing" the results, not what I am going for, just curious.

The Highlander

there is no problem there... it depends on how yo make the dyno pass that it gets more or less power at lower rpms points. Depends on how the turbo's spool up.
