Could've had my car back today from the tuner.....

But there's another issue with the XCESSIVE Lim .
(On top of the hole issue on the first page)
The tuning shop started the engine up, No problems idles sweet.
My 2nd engine rebuild successful !
But there was a whistle down from the lower intake. It wasn't sealed 100% , so they took the XCESSIVE lim off and found the surface that mounts to engine wasn't flat ...

Doh not again!

 

That is really annoying! I was going to order that manifold this week and I am really starting to question if its worth the money... If I pay 500+ for something, it better perform out of the box like advertised!

 

Yeah I don't quite understand why its so bad! A lot of ppl use these and I haven't heard anything bad besides the runners needing to be matched.

Machining something like this flat again is awkward and expensive because of its shape.

I think the only option is to run a paper style gasket instead of the factory steel mazda and see if it takes up the gap. Hopefully that doesn't push my manifold out too much closer to the turbo.

Will post photos soon of the Xcessive un-flat mounting surface.

 

I have heard of people using HondaBond HT in conjunction with the metal gasket to seal unflat flanges... May be worth a shot.

 

Ok thankfully I have resolved this issue directly with Xcessive and they are sending me a new manifold, for which I'm grateful.

 

^Nice!^

That makes me feel a little better about ordering one!

 

On the dyno today !

 

WTF kind of Dyno is that?! I have never seen one like that!

 

Dynapack, supposed to be the most accurate

 

Yeap dynamic hub dyno. Very accurate with repeatable results. Becoming very popular here in nz.
What were the results? Who was doing your tune?

 

Interesting, I have never seen a dyno like that!

 

417 Rwhp at 15 psi. Will post the dyno sheets soon.

 

Nice .Probably got quite a nice tourqe curve aswell I imagine.
Edit re read first post. Factory ports and Elliots tdx61mm

 

 

That just on gate spring pressure? Not controlling boost with link?

 

Seems quite slow to build boost on factory ports

 

Great first run on the dyno. It is very rare not to have to make adjustments and go again. Is there a reason the engine was not revved higher ? It would have made a lot more peak hp with another 700rpms.

I would also check for boost leaks and exhaust leaks and do a compression check to start sorting out the sluggish boost response.

 

Im unsure why the dyno sheets stop where they do. They rev limit is set to 7800rpm.

There is a loud whistle from the upper intake manifold area when boost builds up, but two smoke tests of the system show no leaks?!?! The double butteryflys are wired open.. also ive never used the Xcessive LIM before. Does this create more intake noise then the factory LIM?

But you are right it will be back on the dyno in a couple of weekends after its had a few KMs on it.

 

Also who knows of a quieter external fuel pump than the 044? Too loud

 

Trying to post a vid ...not working

Wait now...

Ok so I have this strange whistle... Also I'm sure that's the turbo fluttering not the BOV.

 

YouTube video


Anyone else heard this ?

 

The whistle is coming from the gearbox bell housing I think...
Is that a feature of Reamemiya twin plates? Lol

 

It sounds like its coming from the turbo, but I have never heard anything like that before. maybe a boost leak?

 

Where is your BOV situated?
I had a slight whistle on my BOV when in idle but never heard anything like that before.

 

It's on the back of the compression elbow . I know right... So strange
