So question for you. Should I wrap this manifold? I know you guys have a coating option, but I’ve always used wrap on pretty much all of my exhausts.

So is wrapping the manifold suggested or no? I’ve seen some mixed reviews/opinions.

Curious to see myself what Killer will say, but I'm sure from the safety/liability/warranty point of view, they will tell you to not wrap it. But I still would.

I personally would black anodize it. Anodizing has the best heat reflection.

Fore and Turbosmart are the best regulators on the market, in terms on holding differential pressure, as far as Cams Kelford 272 will touch pistons with over 15 degrees of advance on AVCS, problem is some times the target thats set in ECU can be overshot, iv had cam go 45 degrees on me before due to oil pressure issue. So if you going with kelford 272s C's i recommend deleting intake avcs. As far as injectors min PW is just to low to have good idle on pump gas, and you will end up compensating it with loading up the engine with lower timing = more heat //

What? You can't anodize SS. At least not the way that you would for aluminum. Not to mention anodizing would make it act more like a heat sink rather than keep heat in. But then there's also the fact that an anodized finish cracks at higher temps.

Ceramic coating is the most effective for keeping heat in as well as reducing corrosive damage to the material. Wrapping will keep heat in but also corrode and potentially crack the material faster. If it's a race car application and you'll be taking everything apart a few times a season to inspect for damage, then it's a wash either way. But for street use, ceramic coat is the most practical option.

So fuel line question for everyone. I’ve been doing some research and following a few builds. I know I need to upgrade my lines from the new dual pump setup to the engine.

From what I’ve gathered I’m thinking 6an from each pump to the “Y”, then 8an forward, with a 6an return and 6an crossover. Does that sound right?

So I have been busy working and buying parts. Ask have been in talks with my shop about fuel lines and things like that. So far I have the following parts:

-Cobb 4 bar map sensor
-killer b holy header
-aeromotive a1000 fpr
-Cobb flex fuel sensor kit
-Id f750 fuel filter
-id1700cc injectors
-grimmspeed manifold and manifold to uppipe gaskets
-IAG competition series engine mounts (90a durometer bushings)

Only things left are my fluidampr, and radium dual pump hanger. Looks like the norm for my shop is -6 fuel lines from the pump to the Y, -8 line forward, and -8 return if I remember correctly. Will also be running a Hobbs switch for the second pump. Looking at early April to get in and get everything installed and tuned.

If you haven't wrapped em already, +1 for getting the headers coated.

FWIW, an -8 return isn't really necessary but never hurts to have it I guess.

I ran -8 feed -> Y -> rails, and then -6 AN return. -6 return is still a substantially greater cross-section.

I'm running a Hobb switch to my dual radium hanger as well. No issues there

They may have said -6 return. I don’t remember. But I trust my shop to build the lines! They have done it probably thousands of times lol. Just can’t to get all the stuff on the car!

All parts have been bought and the STi will be at Andrewtech on April 5th. Hoping to hit that 650+whp mark!
