Just curious if anyone has tested an 18 manifold. On a boosted 15-17?

I have one on my car, no clue if it made an improvement yet. Feels a little softer in the midrange though.

Where does your car shift at? I would think the 18 mani would allow more rpm.

I'm running it on my 16 and was pushing 18lbs of boost with twins but I never ran it back to back with my stock intake. It does like to rev though!

I have an 18 manifold in my 15 Paxton charged. Was shifting at maybe 7300 nothing crazy. Trying to make the motor last a little longer but didn’t work out that way. Power was 771 with e85 no before intake numbers

I'm running an 18 manifold with my Procharged car. Wastegated centri + 18 manifold is the perfect combination for power everywhere.

It feels amazing compared to the stock mani. There might be a hair less torque on the initial hit, but past 6k it really pulls hard. Very noticeable difference. On the stock mani I couldn't really feel it flatline, even though it did. But now that I have the 18 manifold I can certainly feel that it *doesnt* flatline. Power just feels relentless until it shifts. I rev to about 7900-7950.

Didn't work out that way? What happened?

That's why I scooped one up. So cheap for solid gains, and very long powerband. Ya a CJ may make slightly more, but engine mounts and/or modding hood are not worth it to me.

Anhhh I just have a hard time paying 1100 dollars for a piece of plastic. When my aluminum victor jr. On the old race car was only $300. This and a bigger TB look like the ticket.
