Pfadt Tri-Y Headers on ZL1 Dyno Results

Just came across this video of the untuned Dyno pull on a ZL1 with Pfadts new Camaro Tri-Y long tube headers.

On a Dyno jet, it made +50 HP @ 5250 rpm without a tune.

Cool.

My guess is with no tune there will be a CEL due to cat efficiency codes. Also did not see if this was with or without cats. It would be interesting to see these installed with a Rotofab CAI. If the Rotofab is worth 20 RWHP and these are 30 RWHP I wonder what the combo HP would be? I would seriously doubt 50 RWHP (that would be ricer math ) but it would be nice to see an overall gain of 40+ HP.

These are going on my car in a couple of weeks, although it'll be tuned at the same time and also with a pulley change.

Either way I'll post my results - hoping for decent gains!

I was just thinking the same. I dynoed 499 stock, 520 with the rx chiller and now I have the roto fab but no dyno pull and if I can add headers still without a tune. wow
