Pfp superjet problem

[AndrewMcEyes]

xscream says it can be a manufacturing error...
I await further responses from them

They are great to work with, I'm sure they'll help you.

This is the answer to my problem of xscream:

"Hello,


We contacted the designer of the PFP system, and he said that the shape of the chamber was designed to fit in a SuperJet hull with a stock engine; when utilizing after market parts and/or engines in the hull, the fit can change. The manifold looks extremely close to the side of the hull in the pictures; not the norm. You would therefore have to have the chamber cut at a slightly different angle for it to fit properly, or perhaps take the manifold down a bit."


Basically I have to make do...

Or u can take the manifold to the machine shop and have them Mill down the mounting surface to the cylinders a little to clear it more

Ur manifold seem super thick at that area

 

[just joe]

Where the bolt is (recessed area) my manifold is 16mm's

Those chambers can be off quite a bit. I friend of mine had the same issue with his chamber. They all should fit the same. Someone should make this right...they did for my friend.

Measure your flange thickness on the manifold so we can compare it with others.

Sweet it will be easy to tell what is off then

Not real sure how accurate those recessed areas are

Yes my manifold has the same thickness

 

[AndrewMcEyes]

But I do not think we can solve the problem by reducing the thickness.
I also fear of undermining it because it is very heavy.. I know of people who has already cracked so

 

[txsuperjetfreak96]

Right think thats your best option, mines going in an aquabot so hopefully wont have this issue

You think so ... thank you very much.
If this were not enough I could cut the mouth of the chamber and weld it with the right angle, but I think the entrance is "double", so it will be impossible for me to weld inside... correct me if I'm wrong

 

[txsuperjetfreak96]

If it was beveled good enough would b ok, if your worried about it cracking put an extra foam block closer to mani for more support for the chamber

The measures of the dasa engine are identical to those of an stock engine. So xscream did not tell me the right thing ...

@DAG i know he ran a pfp in a square nose...

Protip: don't do it
