Yeah, me too. Mine only runs high 10's at 8 psi on the baby 2.8LC and a shitty tune. And don't get me started about the shop owners car who installed mine. He has to get by with a measly 900 hp and 8.80's out of his. KB's suck.
My N/A car runs 10.8's. Color me unimpressed.
Your shop owner isn't running 8's on a stock long block. Both the Paxton and Roush TVS have run 9's on stock long blocks. No KB kit on the 5.0 has come close to matching that.
Don't mistake what I said, my reference is for the 5.0 only. The KB's have proven themselves on the older 5.4 and 4.6 applications. Just not the case on the newer 5.0.

Agreed. Their horrible intake design is the limitation on that kit.

Yes his MPH was pretty high and the tune was crap.

It ran 131 mph, I just can't keep up with the shifts with my bad shoulder anymore. There's an auto swap in her future. And I never said that 900 came on the stock long block. I'm sure the KB could do it, but for every 1 KB you see out there, there are 100 Roush or Paxton cars. Much harder to get decent stats if no one is really running your product. Shelby seemed to like them enough for the Super Snake projects. But they are junk, I understand. And I'm actually less impressed with the KB stuff on the older cars. My kit, right out of the box, with no changes at all (stock pulley, factory throttle body, etc.) made enough power to go 10.80's at 131. Color me impressed. Wonder what she'll do when get around to turning it up? The bottom line is, everyone has an opinion, and that's great. It's exactly what's kept me doing this for the last 35 years. Not everyone has the same ideas, or does the same things. Keeps it interesting.

He went 9s on 18s with the stock motor and stock converter. Full weight premium. I believe he posted its gone 6.19 or 6.20's with the built motor still on 18s. He doesn't post on forums much.

Pretty sure 8.8x's is his best so far. Car is pretty sick for a full weight automatic car with stock converter.

If you are happy that is fine. Bottom line is the KB just isn't as efficient as the Whipple or Roush kits.
An auto will do wonders for your car.

How much boost? I would like to see some video of said runs if it exists.
True, thankfully there should be a CAI with it here soon.
It's been a while and I am not sure where I read it but I recall some significant gains to be had with an improved intake setup and some enlarging of the throttle body area.
I believe there is a pulley size limitation as well which means you are going to be stuck at a certain level of boost.
This is where the Roush and Whipple designs shine.
Lol having owned Paxton, Procharger, And most other blowers. Procharger > everything else out there. Every Paxton kit I've had has been 100% junk.
Of course this isn't in reference to the Coyote setups. Just Procharger vs Paxton, isn't even a fair comparison IMO.
I will agree that the Prochargers work very well on the Vettes with anything a d1 and up. The P1sc just isnt great.
On mustangs its a different thing all together. There is a reason why there is so many more fast 5.0s running the Paxton and JT Vortech kits so its hard to argue that. In order to run the same ETs as the Paxton/vortech group the Procharger guys have to move up to a F head unit which some (not all) find it too obnoxious to run on a street car.
Search any of the major boards and you will find what i am saying is true. There are some fast procharger cars out there but its not the norm and almost everyone ofbthem had a bitch of a time to get the car running right.
