I'm in upstate NY Hudson valley region. I would be shipping this stuff to Boostin because that is who AMS is recommending. SSP would be receiving the transmission.

Razorlab - the gtx Garrett compressor seems to need higher boost levels to make power vice Borg or precision. Since I'm aiming for 600whp MINIMUM and more like 650, I was thinking it would take Max she is capable of which is 3.4 Bar. Any downside to using Omni 4 bar sensor ?

 

I would say the stock frame needs higher boost levels to make power. The GTX wheels in a full frame do not. If you are going bigger than 32psi, then yea, you need a bigger MAP sensor. Buy two Omni MAP sensors. One for now and the second for when the first one fails. Rinse and repeat.

 

Is there a different 4 bar map sensor I should be considering ?
I scored a set of GSC S2 cams for the head.
A co worker of mine who is familiar with old school v8 engines was telling me that the cam profile of the S2 with beehive springs "wouldn't last long, and count on replacing them every 5-10kmi". I think he doesn't know what he is talking about when it comes to modern dohc design. What is the life expectancy of the valve springs with a cam profile such as the S2 ? I never heard of that even being mentioned as a concern.

 

I recently came across this manifold. I was wondering if this would be an alternative to the MAP manifold. Looks like there are options to use a v-band setup as well. Maybe someone can chime in on it.

Looks nice but no ewg designed in.

 

I just saw this posted today, on a Evo 9. Interesting that for the 9, they have a ewg in the manifold. I wonder if you can get an Evo 10 version with one?

 

Holy crap, I could have bought a G-series with internal wastegate and used that manifold. Wonder if I can return the turbo unused. Cast stainless is where it is at.

 

Well, then again without an EWG there are NO DIVIDED v-band inlet turbos that I can find. It would need an EWG in order to keep the divided runners. Otherwise having the exhaust housing have collected paired runners doesn't make sense if it goes into an "open" turbine inlet.

 

Pretty sure my MAP manifold isn't divided in the collector. I think you might be over thinking it.

 

Yours is open all the way, different design. I have a strong desire to keep twin-scroll, which is what lead me initially to the AGP manifold. I landed on the MAP OEM style cast stainless manifold also because it is durable and twin-scroll. I want my cake and eat it too; v-band, cast stainless, twin scroll. I can't have it !

 

I wrote the company to get the scoop on this. Garrett does make g series with IWG and vband (not twin scroll), so that's an option. I have to decide to stick with what I have on hand: MAP stainless and GTX 3076R gen 2.

 

I never heard back from ARTEC. However, I have been starring at the design and I think it is superior to the MAP manifold. The MAP runners are too large, and this design keeps them tight and much more EQUALIZED which is part of the point to twin scroll (to keep the pulses timed correctly out of phase). I just might grab the stock flange one, bolt on the GTX3076R Gen2 and sell my MAP manifold as a used item. I would probably only be out 500 bucks in this change up. It looks vastly easier to get to the hardware for mounting!

 

What a beautiful manifold!! I know I'll need a new mani at some point, still with the stock one, this has moved to the top of the list!

 

So I grabbed an ARTEC with MHI twin scroll flange to bolt to my Garrett GTX3076R GEN2. I'll sell my MAP manifold on here, and won't even charge for the pretty color "upgrade" it has now vice when new....

 

Back to back pulls with the MAP vs ARTEC! 😁

It looks like an easier install for sure.

I am about to completely pull my MAP manifold to fix the remaining installation issues the “professionals” couldn’t handle. I will update my thread with what I have learned during the process.

What is your timeline for the build?
