Z1 Upper and Lower Manifold
Anyone currently using the z1 upper and lower manifold now or in the past? Looking for some feedback on these items. Thinking of pulling the trigger in the upcoming weeks.
I have seen a few people saying motorydyne upper has better torque pick up in the the mid range, but the z1 has a more consistent increase throughout the entire and better top end. I know motorydyne does not make the lower so I think I would end up just getting the 2 from z1. But anyone that can chime in is always greatly appreciated it.

Not for nothing but isn't that something you should have looked into before your recent trip to RT tuning? Have you priced out the retune?

Just from what I have seen on the bill, it won’t be that bad. I think the dyno is 520 somewhere around that, labor about 90 per hour. I know lead times on some of these kinds of parts from z1 could be a few weeks, and motordyne seems longer. Rochester from your build I know mine is never going to be truly done lol. So I know having to go more than once was something I am ok living with. I’m coming late to the party a lot of you guys have been at it for years, so I know there might be somethings I can’t get done all at once. Slow and steady.

I've had good results from ported upper and lower nad retune. The Motordyne M370 is a HR manifold with longer runners that been fitted to work on our VHR. its not ported. the longer runner is what that contributes to the torque increase but will run out of steam on the top end.

I have had the M370 in my car for over 4-5 yrs, I really enjoy the torque - getting up and going from a dig is very nice. I don't track my car, so I'm not worried about any top end loss. I picked up the M370 from a fellow member here via the classifieds. Honestly, a guy who lives around my area has the Z1 upper manifold and he was impressed with the overall speed of my car compared to his. He is on a stock exhaust as well, so really not apples to apples. I'm not sure what the hp difference is between the two, but would be interested to know.
