1badgsex -- i respectfully disagree with your post, that mindset does not help advance our sport in any way.

the car you are speaking of in the above post has our twinscroll 40R turbokit and after my recommended setup made 640whp on straight pump gas... a different customer of ours just made 540+whp on buschurs dyno with stock ecu and pump gas (i think that was the record)

when there is room for improvement, take it.

I spoke in detail with Sean today. The head testing was not done back-to-back. The head that was on the car was on the car before it rolled over in the old chassis. Then put in the new car, dyno'd here, dyno'd at Sean's etc. In other words, used for some time. The actual difference in power and not in back-to-back testing was 11 whp, 694 whp with our head and then 705 with the HG's head. I can live with that, especially when I'm not shocked to see 11+whp from a fresh valve job and springs and nothing else done to a head.

There was also a cam change done in the car. Peak power was up by 2 whp with our cams over the new ones.

Looks like our parts are doing pretty well compared to the thousands of extras being spent to replace them..........
