ported/polished/coated manifolds 3Q's in 1

[RoughSilver92]

I was googling earlier and came across this:

Near the bottom are some svx manifolds. The coating of both sides seems like a solid idea. These would help the performance of an NA car also, correct?

Also, on the first page they talk about coating the intake manifold, and also removing the tgv (tumble generator valves). Would thermal coating the intake be a benefit or a bad idea? I know my intake manifold gets hot to the touch, so I would think coating it would trap heat in.

Now on to the TGV. I could have swore I came across a post or two before mentioning TGV on the svx, but now I can't find any. Do we have them, and is there really any benefit to removing them?

I've seen those manifolds mentioned before. I think Svxfiles has his intake manifold thermocoated.

Yes, yes he does!















No, we don't have tumble valves.

Check out my old locker about the coated manifold, plus the PHENOLIC spacers.

The idea of thermal coating the intake on the inside is to isolate the heat to the metal, and keep it from radiating into the incoming air. Cooler air charge = more power.

As for coating the manifolds on the inside...not sure there's much point. Maybe to keep the heat in the exhaust gases, instead of heating the manifolds as much, which then radiate heat outwards. If I had an F/I car then that might be important, but I don't see any reason for that with an N/A.

So...
Coating the inside on intake+phenolic spacers = good
port/polish exhaust manifold = good
coating exhaust manifold = ok for NA, but probably $ spent better elsewhere
and we've already got tgv delete

When you get something like an intake manifold CERAMIC coated, they abrase (sp?, Di is not here to ask)
both the inside and the outside, they coat both the inside and the outside, at least that is the procedure at Thermal Tech Coatings.

The only person that I know who has had their exhaust headers coated, at the same facility, has had the 2000°f coating flake off.
I have been VERY happy with their work, and have sent and will send them more things in the future.

Yes.
Yes.
My supercharger engineer tells me that coating at a lower temp would last longer.

Yes, GrimmSpeed has recently started offering PnP on the exhaust manifolds. They will also PnP pretty much anything else. I am currently talking to Mike @ GS about the pricing for the intake.

I say $280 is a ridiculous price...

For the benefits and specifications of ThermalTech's "cermakrome" ceramic-metallic coating, click HERE

For the benefits and specs of Airborn Coating's Aluminum Ceramic coating, click HERE

I have used them both and they are great to work with.

Well to get the coating it's $339.98!!!

My lord there is no way this could be worth THAT much money...

[Sov13t]

It is all relative...

If that $339.98 is going to keep your $18k (referring to your signature) investment from burning up - I bet you will pay that much without blinking.

However, if its purely for looks and presents no gains (on a relatively stock engine) $339.98 is a bit expensive. I recommend sharpies instead

I didn't think of that.. Protecting the "investment", that is.

Good point. As for the sharpies, I'm not sure why people would want it colored anyway. Not like anybody is looking hard at your exhaust manifolds in the first place.. lol

I had my Buell xb12 headers coated by jet-hot and am very satisfied. I think it cost me around $170 with shipping and all. I have no idea what it would cost to get an svx intake or exhaust coated. They do offer discounts and run promotions regularly, I got 10% off.

Yeah the coating is only around $55.00 but it cost a lot more to have them ported and polished...
