Oh my good Lord. Where the HECK is it gonna go?
That sidewinder is absolutely sexy. The motor being turned that way is the only way this would have worked. On our cars a compound build one would almost have to be rear mounted. Either that or some crazy hard bends which probably wouldn't flow too well.
I've often kicked around the idea tho 50 trim off a log style manifold back to a similar turbo you have "rear mounted". Not that big tho. Basically an STS style compounded with something else. Would need an oil pump as well.
But anyways this is ridic man.
I'm actually a little confused. Shouldn't the 60mm gate be before the 28r somewhere?

yeah, my original plan was rear mount a gt35 with the stock manifold and ko4 upfront. But I go to car shows a lot, and having a rear mount will not really be "visible" to judges and people. I have to explain to them the rear mount set-up...and they have to bend down to see what's going on.
That's why I decided to try to fit everything inside the engine bay, so its more "visibly appealing" at car shows....and no more need of bending over
Plus it just looks cool having an overcrowded engine bay anyways, we're still on the initial phase of this manifold fabrication. You'll see the 60mm wg attached soon on the set-up!
maybe!

Now both the gt2871r turbo and the gt4294r turbos are positioned inside the engine bay!
Once the god forsaken notches required for the gate placements (the 60mm primary uses 2.5" pipe man, it's ******* huge) are finished so they have no seams, serious bracing will be constructed across the top of the Valve cover and to the turbos, headers and specifically where the gates attach.
They are so far away from the engine they will be prone to oscillation at certain frequencies and eventually cracking without significant bracing and double wall at the gate attachment points.
THEN having guaranteed placement of key components and they're v-band orientation, we will add 3 flex/expansion bellows to allow for thermal expansion and to some degree vibration/misalignment.
The proper kind of flex bellow, NOT the braided variety. those have no place upstream of a turbo!

If you have not already sourced the flexes you are talking about, I get them from Ameriflex- Copper Bellows, Metal Bellows Stainless Steel Bellows. They make them for Formula One cars, fwiw. I use them on my drag car and they have never let me down-

This is so f***ing nuts. It would have been sweet to see a 7670efr compounded with the 6258 or something. I still wanna rear mount a big one some day with a small one up front. Just to say I did it

the EFR turbos are a bigger in physical size compared to the garret turbos......due to the all in one package. That's why I don't think two efr turbos will fit inside the engine bay. Unless the big one is rear mounted.
We are currently using tial turbine housing to get the most out of the full v-band benefits..........easier fitment.....compared to non-full-v-band turbine housings.
But who knows, in a cobalt LNF set-up, two EFR turbos might fit! I know that in a kappa platform like mine, its already cramped up inside.....and lots of relocation needed.

will try 600-700whp!
If it will go higher, why not?
I'm not really going for the highest possible whp that I can get for this set-up...........I just want to to have a decent power with a minimum lag....and hope it to be reliable/driveable/streetable on a daily basis...and that's why I tried the set-up

I don't see the need to use EFRs in a compound setup. The whole point of the compound setup is so that it will initially hit as hard as the small turbo will make it. Plus they are much happier at higher pressure ratios which means you would need to run 60+ psi after compounding in order to utilize them efficiently. Although it would be pretty cool to see 60psi at <4000 rpm.

Plus with the almost 1:1 turbine/compressor weight ratio.......due to the gamma ti turbine wheel.....the EFR has a very fast spool up compared to any turbos in the market.
so not really needed to be compounded.......

ZZP stage 1 w/ bigger fuel lobe just arrived today!
these cams together with my secondary fuel system will compliment each other to provide enough fuel for lipstick!

If you guys didn't receive the notes in the intake cam box, install the hp fuel pump without the gasket when installing the cam with larger pump lobe. We designed it to optimize the pump stroke in that configuration and also take advantage of a little more spring pressure for better control at high RPMs. Just use some RTV on the mating surfaces.

yeah...saw that note when I opened the box.
thanks Matt!
yup thats me!
