Mazda 626 Intake Mani Info thread

drrrr They said there might be an opening at 2 or 3, so I called when I was on my way and the guy that was getting his car tuned at 11 was still on it.... That's a hefty bill. Anyways, I just ordered the QTP cut-out, so I think I might wait until I get it in so I can run some comparative pulls.
 
Depending on how your dyno goes, i might get a 626 mani. Otherwise I'll get a protege mani, remove the vtcs, and port it.
 
Why not get the 626 and port it that way you don't have to remove the vtcs and go back to stock if you want.

There's nothing to put to rest. It adds hp and SU has the dyno to show it. Maybe there is a difference or two on the one they sell, but dynoing the manifold isn't going confirm anything.
 
I wouldn't mind dynoing my car but I have a lot of stuff going in to it at the same time so it will do no good to you guys.

I want to see dyno numbers from a forum member. Not a webpage promoting the item.
FWIW, the butt dyno says the SU website was pretty close with those numbers. 10psi before the manifold feels like 7 now.
 
So let me get this straight. Someone, somehwere is going to dyno this thing both N/A and F/I? I am interested in using it for N/A and selling the ported VICS (less VTCS) manifold I have and getting the 626 if it shows gains.
 
Just from experience on N/A engines, I don't think that there's much benefit without work to compliment the manifold.... Otherwise I'll have pre/post manifold dyno's shortly... Maybe I can get an hour before I work Wednesday..... But I'm thinking I'll buy an hour or two once I get my exhaust cut out on.
 
is the EGR pipe required to get with the SU intake mani? or do you not really need it..i was just curious because its a 70$ option.

STOP IT!
There is no SU talk here in this thread....Lets keep it focused. PM Cullen or SU if you want answers about their product....This thread is about the 626 Mani info and NOT SU's mani....
Thanks
