I was looking at your dyno charts on your website and was noticing the HP and TQ curves with the cam you have (which is pretty big). I was wondering why you werent seeing any bigger numbers with that "cam-only" than the 322 rwhp and 313 rwtq? I would have thought your your rwhp to be in the 360 range at least and tq to be fairly larger? Just wondering out of curiosity.

 

360rwhp thru a 4l80e, tcase and 32" tall tires? where do you get your expectations from? i dont have a pile of bolt on's and no headers runing thru the cat's even.

 

With no headers and having cats I think he was pretty much in line. Headers make a HUGE difference on big cammed LSx motors. I've seen LS1 guys do a cam first and dyno 340rwhp then do headers and redyno at 380rwhp.

I think Blk6.0HD dyno'd like 344rwhp with a beefy cam, headers, no cats but zero tuning. So I think Parish8 was right about where he should be considering.

I'm trying to get Blk6.0HD to redyno now that he has tuning and injectors. The truck was much faster after the tuning. Sucks for me when we race though.... F'ing 6.0L bastards!

 

Thats right, I forgot you were spinning through a tcase, and I didnt know you supporting mods when you dynoed thats why I was wondering. Did you ever run with just cam only at the track?

 

i did but i dont remember my exact times. roughly think i was in the mid 13's with the stock 6.0 and a loose stall. then i got the cam and tightend the stall and it slowed me way down, into the mid 14's or so. big cam and tight stall are not a good combo but i was geting ready for the turbo set up and a 4500+stall is not ideal for turbo. it was a dog out of the hole but once the power came on it felt prety good.
