So even with the drop in KPA you gained some HP that’s pretty sweet!
I’m still debating if it’s worth the money to get a ported 95m Tb to match the ported LT2 or if the stock tb ported will be enough.

i was expecting to see the kpa drop after the intake swap, well hoping at least. if i planned on keeping this manifold on the car, i'd have modified the intake to accept the lt5 tb. after looking at the LT2 manifold up close, idk that it would gain much from porting other than the use of a larger tb. the runners look pretty good as delivered.

It's a v8, it's a bolt on ss 1le m6 with a high-ram. The guy is on the FB Camaro pages on FB, him and Pray have been pretty open about the build. Basic high-ram fbo car. It actually doesn't have a UD pulley so it's arguably not fbo.

Car performs great for how "little" hp in put down on Prays dyno. There was a regular ss recently with the same combo that made a little more. Better E content and lighter non 1le brakes and tires.

I think you might be hearing things.

SS 1le did jump a little early right on 3 during the honk.

According to GPI should gain me 20whp from 6000-6500 over stock and not lose any low/mid range, and from what I’ve seen 2’ longtube headers with a 3’ x pipe should gain around 15whp over my Cat delete pipes and should help with top end. I still need to send out my tcm to get unlocked too, that should really wake the car up.

How about a 150 shot for more "top end"

I can’t wait to get mine!
I’m curious if I’ll need any tune adjustments because it’s currently tuned for the stock intake
Or even if it doesn’t need a tune adjustment I wonder if it’ll gain anything from one

That would definitely be the best equalizer forced induction vs N/A (nitrious assisted) 🤣
Maybe later down the line.
I would like to get the car to run 10.9-11.0s with bolt ons first and see what a 150 shot will do
