Yeah it sounds about right but I'd definitely be interested in seeing what he'd make with LTs. Theoretically with the headers, he'd make ~470 whp if we're basing that from his previous numbers, which definitely seems like a very high percentile. Maybe his buddy forgot to mention the headers? I know it's tough to remember all the mods. I'll go watch the video, maybe I can tell from it.

Also, slightly related, what's the expected outcome between an R and the gt350? Saw a local guy with Chinese headers, 18 mani (not ported I believe), cai, and e85 lund tune put a couple lengths on a stock gt350. I imagine the R would do the same? Forgive my gt350 ignorance

Edit: Nope, I can't tell (maybe someone else can). Regardless, everything about the 18 mani is great to me. Just saw a ford dealership post some for sale for $200 on fb the other day. Not sure there is a better mod for that kind of price.

He does not have headers as BmacIL stated but I wouldn't doubt he would get close or into the 470whp range on the same dyno. This dyno usually reads somewhere between what a dynojet and mustang dyno would read and uses SAE.

I got mine from Levittownford for a good deal. In the upper $200 range with free shipping. Honestly, for the price it's probably the best and depends on the application. For boost a ported boss manifold is the best option for the price. But I'm not disappointed at all with my setup with the ported 18 manifold and boosted. I made peak hp @8000RPM+. :headbang:

Ah yes 8000 rpm... that’s really what makes this manifold so glorious. 500 extra rpm of pure freedom and bald eagles

I’ve never heard so much nonsense about “DA” and online calculators. It’s simple, go to the track before and after with similar weather conditions and see the difference. If you don’t live at sea level and you’re in the mountains then oh well. Your car runs what it runs like everyone else around you dealing with the same weather and altitude. Lastly, these lesser minded people who claim stock manifolds flowing less air is better overall / peak power than a manifold flowing more air makes absolutely no sense. You either are in it to win it or you’re obeying local traffic laws.

[MENTION=10281]BmacIL[/MENTION] is picking one up for me! Some collaboration between fellow forum members. That’s pretty cool.

Looks like I will be joining the 2018 manifold club lol

It makes peak power at 7250 with this manifold, provided it's got a CAI that allows for it. 500 rpm shift up and huge power increase over 6500.

My hp curve and stock cams are stubborn and say otherwise ;)

I could definitely see 465-470 with headers being possible. Ronnoc made 455 on pump gas w/ headers, e85 adding 10-15 whp is not unheard of. Mind did 423 on E85 with headers on a Mustang Dyno that reads about 10% lower than a dynojet. So it is definitely doable I would think.

[MENTION=9177]Demon Coyote[/MENTION] you were sitting shotgun for this too? Man that car is fast!

Yes I can see that with E85, I gained about 11-14whp when I was N/A after switching to E85. Most definitely, but unfortunately I don't think we would ever get to see it since he wants to go with a TT setup.

No sir I was not sitting shotgun. Yup and that 18' had a GT350 manifold, 10 speed, and I believe a tune from Ford.

So the '18 mani makes power up to 8,000? I thought I should be shifting at 7,500?

For my car it did but I am boosted. For N/A 7500 seems about right.

It makes peak power NA around 7250. Shift at 7700.

Also, an FYI that [MENTION=9177]Demon Coyote[/MENTION] and his friend have demonstrated. The IMRC solenoids DO have a open spring, so if you just leave them as they come on the manifold, and don't hook them up to vacuum or to the harness, they'll always be open. No lockouts required.
