So iminhell had dyno sheets showing before and after port?

I put my TB on the intake, put 3 of the 4 screws in and tightened it down. manually held open the butterfly and took a marker and made the ring. If I trimed to the outside edge that is where I will have no lip/step when transitioning from TB to intake manifold.

I will see how that matches up with the gasket.

I am doing it because I am waiting on funding to get other parts, and thins kind of work costs nothing (or next to nothing) since I have all the materials. Just takes time, and I can count this as working on my car.

If it gains me nothing then no harm done, just as long as it wont rob power or be a problem under boost.

When I have the TB on to mark up the outline I did not notice the butterfly contacting the opening at all but was not paying that much attention to that part.

I don't think he has dyno sheets before and after... I more meant that his car flows really well and from his dyno runs he puts down hella good power for a NA motor... He will chime in I'm sure... He knows a lot... I just meant if he feels its not a big deal to do it... His hp shows he must be doing things correct...

So since I am dealing with an aftermarket TB (The Focus-Central) that does not use a silicone gasket but rather a paper filter like below:


So if I fill in the marked areas in the picture in post #9 and then sand down the surface (mainly where the screw holes are) so that its a true flat surface, I should not have to worry to much about seal right?

Filling the voids with Epoxy on the intake manifold would increase the surface area that the TB, gasket, and intake manifold make which means I would be reducing the pound per square inch of force being seen. The paper gasket also unlike the silicone also has more area. The reduction in clamping force is likely not noticeable.

So with the paper and the raised area do I not need to worry about trying to get a seal since I am not trying to line up plastic with the narrow gasket?

Thanks for the help.

Interesting info as my 2000 manifold is still on my Kona. Been thinking about removing it cuz I would like a 65mm throttle body for the improved throttle response. Wouldn't mind portmatching it a bit to help with flow some.

My bad for leading you astray there, not familiar with the aftermarket TBs. Thinking they used Ford OEM type gasket. I would try NOT filling epoxy first. The bolt hole bosses are higher and so is the sealing surface, that allows for more pinch on the gasket or what I said at one point. I wouldn't go to filling voids until forced to since it all must be dead flat then and your gasket loses crush when the load spread out like that. Better to have localized crush at the high points, it seals better.

In your case grind away but be careful, plastic moves faster then sh-t and you can't put back on what you've removed.

^^ No worries. :-) Cant you use a epoxy putty to reform or patch? like JB weld putty or POR-15 Putty. its sand-able, seals, adheres to plastic. so you can recover.... but still. So with the type of gasket by narrowing down the contact patch I will be increasing the force seen so should be making a better seal.

Thanks for the input, I will move forward slowly. I may be doing part of it by hand or low speed drill press as my dremmel is stuck on high speed due to being burnt out. so it will be low and slow.

Yes.
And I agree with your summation of the reduced clamping force but increased sealing area.

The problem you will run into, and I can see the threads in that manifold are already shot, is the plastic threads don't hold TQ.
I never did it but, always wanted to drill and Heli-Coil the manifold and use studs instead of bolts/screws. It increases the clamping potential and should ensure a leak free seal.

I'm thinking it'd be easier to either double gasket it or cut the gasket holes around the screw bosses larger. The little rise should come close to matching the thickness of the gasket.
In stock form they are there so you don't over TQ the gasket.

So I think I might tackle this over the weekend (the fill in at least). but will use JB weld, I can get 1 oz tubes of the two part system to have 2 oz. where the plastic epoxy is only .85 oz for the same price.

I need to get new sanding drums for the dremmel before I can start the porting.

The studs are a good idea. I might swing by a fastener store next week and see what they have. once you take the TB off and on more than 2-3 times the plastic looks shot.

Take it from me who has removed the tb a dozen times. The top two screw holes are shot now and just free SPIn. I did get some studs to go in there but the nit just keeps spinning as well once it hits the tb

I have a die set So can drill it out, tap the plastic, but in a metal helicoil and then use red loctite on the stud in the body of the intake manifold.

This will be a nice improvement so I dont have to worry about a leaking TB gasket or poor seal.
