Well... Crap man. I'm sure those weren't the results you were hoping for. Think you swap back or just leave well enough alone? Gains are gains at least!
It didn't surprise me at all. History has shown that the stock ported manifold Intake makes similar horsepower than both MSD and this lingenfelter Intake as well. That is probably one of the reasons Lingenfelter is highly recommending the 95mm TB....to show even additional gains if any. So without the 95mm TB we have no idea. Thanks for posting Arizona Z06.
This is why I'm only going with a set of lightweight OZ Super forgiato's which with a new tire i can drop about 45 pounds of un sprung weight + will do a set of lighter rotors . May do a Fab speed cat delete since i ordered it already . Question i have is the gains with a cat delete due to better exhaust flow or is it that the car is leaning out creating extra power ?
Kracka, looking forward to your dyno runs. I think the most truthful statement was from Cicio, about exhaust mods. Looking forward to paragon air intake testing. Bolt on 500hp C8 cars seem doubtful. But we can hope.

Yes agree our nature is we all can't get enough HP/TQ.
However, still pleased as compared to C8 stock numbers of 429/410, this particular C8 has seen an improvement of 27.4 RWHP/32 RWTQ along with a reduced curb weight, I'm good with it.

That's what counts.....as long as you are good with it. But you sure did opened up some eyes. Members now can make a wise choice regarding those two application. For probably a comparison......Matt the youtuber, installed the AWE Exhaust system which claimed 19 rwhp, ported 87mm TB to 91mm, ported intake manifold by Carlos RIOS, Blue Attack Filter, Michilen 4s and the soler Throttle controller. Drag strip numbers results in good air 10.93@122.51. Done at Bradenton Motorsport Florida. He eventually went with the ported 95mm to 100mm but it appeared that the car went slower certainly didn't not improve his ET. Hence should have stayed with the 91mm. Or maybe the track conditions were different. His latest dyno results was 435 rwhp....not even close to your results. Bone Stock C8 same dyno and time 424rwhp. I hope that makes you feel even much better.

I'm happy with the pTR. One difference between the two Dyno's I failed to mentioned is that the temperature was 20 degrees cooler on the first Dyno. Not sure if it means anything.
Dam.Having a car stuck at around 450 rwhp would blow. The most enjoyable part about having a fairly quick car is the ability to make it faster about every year. But really all that matters is that YOUR happy. Enjoy it.
