Alright guys sorry for the delay.

I got slammed busy with steering wheels and stuff but I did manage to remove the old gaskets last week and have been testing the new ones I got made up for this manifold.

As you can see from the pic, I melted CYL 3-4-5 pretty badly and the new ones are below the crispy ones.

No leaks to report and things are good to go! Theses new gaskets will ship with the SC Manifold at no added cost! You're WELCOME!

New gaskets are made from FluroSilicone (spelt that wrong possibly) and are rated for about 400* temp and are fuel resistant to degradation.

These suckered aren't cheap on a custom application like this, but will outperform OEM gaskets all day.

Can I buy a couple sets, or can you direct me to where i can get them for this? It seems that stock ones wont fit this manifold.

The OEM gaskets won't fit and tend to melt due to the added heat transfer from the block onto the aluminum Manifold. It disparate quickly but it's saturation point still occurs.

The gaskets should be available from Sharp Customs If you reach out to Marcus. :)

This thing flows air nicely. Some results with our F21-series turbos at only 18psi plenum pressure. E85 with supplemental methanol fuel. Oh, also: emissions-compliant stock downpipes.

These turbos are in testing and not released publicly. But the manifold is working great. My only suggestion would be for some kind of resin/insulating spacer between it and the cylinder head. Heat conducts through that flange really quickly.

I believe you but on what basis does this show that it flows more air? Am I missing something? Do you have a before and after?

And I just wanna say that may have came off very forum jerkish but that's now how I meant it.. I meant it like I wanna know lol

To be clear could we get a list of what injectors WILL work?
I'm guessing you can't go too short be a use Ls7 is the shortest.. Then you could use spacers for what ever else?

Install this over the weekend and the brake booster line definitely needs to get replace with a rubber hose. Does anyone know what size rubber hose would work?

I can sort the jerks from the folks who want meaningful data. I reckon your question puts you in the latter category. And I have to admit I don't have comparative airflow values for the stock versus this unit. Not that we can't do that. We have a standalone mass airflow sensor fitted to our intake system that gives us those data every pull. But for now, and on a less "qualitative" standard I am simply saying that this manifold is performing well.

Do I think this upgrade will breathe new life into your stock turbos? No. But is it well-suited to a more advanced setup? One which requires supplemental fueling? Definitely yes. I'm really pleased with it.

Hey Doug, since you're having luck with this manifold. Thought I would ask. Are you using the gaskets supplied?

So I've been driving myself nuts trying to compile exactly what injector will fit this Lil fella.
After speaking to sharps they stated that it is designed for an Ls3 style injector.
These are the smallest of the bunch.
They measure 38mm center to center of the orings..
That's what your looking for..

I'd assume that you could use a larger one with spacers if you choose but I can't confirm that it clears the hood ect.. I think it would but not sure, only thing I could think of with it not fitting.

My e92 has new motor mounts & 1/4" rail spacer; hood appears to clear approx 3/8"

Good to know.. If how ask me 3/8 is as close as I'd wanna be with a high power motor lol

If you could can you post up some pics.. Kinda like eye candy and underwood porn lol.. I'm sure the vendor would appreciate it too :)

Also where did you source them?
Basically
What Injectors?
Where did you source them?
What if any issues?
