What are the main advantages for the forward facing vs. the center mounted. Also what is the advantage of the divided flange? I just need these answered and i'll more than likely be joining

forward facing allows your down pipe to go over the wastegate. also different turbo location. center is going to give you better room for a MAF setup.

divided flange if done correctly, is twin scroll i think? matched to a turbo its suppose to be better response.

^dont quote me on that, i could be completely off. someone care to chime in? iirc its half the cylinders go into one side, the other half the other.

UPDATE:

I talked to kyle about options for the manifolds.

So:

1) forward mount is no extra cost

2) twin scroll is no extra cost (divided)*im still talking to him if he understands what it is. i believe we want 1-3 cylinders into bank 1 and 4-6 cylinders into bank 2.

with that being said, you want dual wastegate locations to accompany a true twin scroll (fullraces manifold). if i understand the concept correct, you want each bank completely seperated. so youd require 2 wastegates. Some manifolds combine both sides into one collector for the wastegate though.

3) if you want an additional wastegate dump, its 50+

and he also clarified, he does not add the wastegate flanges.

Here's the responseI got from Kyle:

"for your first question, there is no extra cost for any options, be it split pulse, forward mount etc etc, the ONLY extra cost is twin gates, which will be $50. I also need to point out that we do NOT supply wastegate flanges, as they cost me $50 each plus delivery, and its a complete waste when the end user will get them with their gate anyway, surely if a car has o have intercooler and dump pipes made they can do 1 single weld on the gate flange:P"

Besides that, I'm sending a full payment today. The GB is still on but I'm watching USD loose against the AUD. As of right now the price is $805 USD a $75 increase in just a couple days. With the rate cut I think it will fall even more.If the GB fails I'll just pay the difference.

ASAP for our own good. The USD keeps dropping value. contact Kyle at [email protected] let him know about this GB.

Mine was twin scroll with 123 and 456 being separate. Each points up one side of the scroll in the turbo. If there's only one wastegate, then there's a small gap between the end of the divider flange and the outside edge of the runners so gas can waste from each set of cylinders. Hard to describe.

I can't believe you guys are getting such a good deal! I could sell mine to a sucka and get a new one for wayyy cheaper than I paid for this one. Then I'd have to get a new WG flange :D

eh? - Did you do a gb too or is he confusing me with you in your first post?

We are in the same GB. Krayton got a response from Kyle before I did.

BTW: do you have installed pics of your setup?

Put me on the list for a twin scroll, t3 flange, and have it forward facing. Im ready to get this thing goin

Also is it actually beneficial to have twin wastegates?

"Happy to do the same deal for you again mate, altho last time I had like 5 orderes to start with, and only ended up with 2.

Other than that, the price would be $1175 AUD including shipping to any state in the US. Regards.......................Kyle
This is the phrase I was referring to. Sounds like the gb I did when everybody backed out at the last minute except me and Seth.

And yep I have installed pics on my "Winter Project Update" thread.

And no twin wastegates will not benefit you since you want most of your exhaust gases to be going thru the turbo to spin it. Probably don't even want a wastegate bigger than 40mm either. Depends on the application.

i talked to kyle more about the twin gates. he completely understands the concept and how it works.

heres the email:

99% of the manifolds I build are a proper divided manifold, but have a single wastegate outlet, it just combines both sides of the split. At this point in time I have only done testing on one vehicle, specifically with twin gate vs single gate with pipe joined, and found very little difference. I agree with the PRINCIPLE that the outlet should be split, but in practice and application, I don't feel its worth the hassle.

It definately doesn't hurt performance a great deal, as a I have done mUCH testing of a split turbo on an open manifold and then using a proper divided manifold(with merged gate) and in ALL cases picked at at least 10% more power and 500-700rpm of spool:P

ok that really clears it up. I guess the twin gates would be beneficial for really high power goals but im shooting for mid 400s so one will be good for me. And was he saying that the twin scroll picked up 10% more power and an earlier spool? and would this be ok for me two have twin scroll if my turbo isnt twin scroll?

Twin scroll is referring to the divided collector i assume. I'll just go ahead and get the divided collector(twin scroll?) for the future

Ok here's the "list"

1) eh- paid in full2) krayton 3)MATTs144)dualcert (uber95?)5)s14_sport6)DriftingisLame

I'll need a deposit from you guys or you guys can get together and choose one person to collect the deposit.

toadx8u- I wasn't given a specific time frame but I'd like to get mine asap. I paid in full already but you guys can give a $100 deposit and the payment for balance due won't be until they are done (2-4 weeks first come first serve I guess). I think these are all custom built to order so it does take some time.

Krayton and myself were originally talking about overboosting and such with the ssac manifold. I saw how low the AUD had fallen and figured I should do a new group deal for the 6boost manifolds with the same terms as the one you did. I referenced you GB in my email to Kyle. Krayton was the first to know about it.

I also already paid too guys. Sent him the full payment.

Im trying out the twin gates since im going for high HP and want a true twin scroll.

Anyways, if you guys need someone to collect, im sure eh? or myself could do the 100 deposit collect and send off.

eh? is that ok with you?

Okay Let me get this clear.

If I were to order a Forward mount twin scroll, t3 flanged, Single gated manifold, the cost would be the regular $1175 AUD, or $805? USD?

The price of the dollar is fluctuating quite a bit, and I'd like to get in on this before the price changes. If I send a $100 deposit now, is the $800 price locked in? Where do I send the deposit?

price would not be locked in. the fluctuating dollar doesnt affect him with AUS vs US dollar.

yes for that setup, its 1175AUD.

Damnit, I guess my first question should have been.. Will this fit an S13 chassis with an R32 crossmember? I dont see why it wouldnt but I really should have figured that out first lol.

Who is collecting the deposits? Or do we send 6boost the deposit directly? When is the rest of the money due?

The price is $1175 AUD. When you pay with paypal you can send the payment as AUD, there you will see the real final amount (mine came out to $807 USD) . If you wanna lock in you're gonna have to send the whole amount soon. If you wanna pay in full get in contact with Kyle himself and let him know about this GB and which style you want. Or you can send the deposit to Krayton or myself.

I'd personally rather be transparent and let Kyle handle everything but Darius didn't do a good job harassing the other potential people in the first GB.

j/k lol.I emailed krayton and we'll see who's going to collect the deposits. Also beware there are paypal fees, so in the final payment you're gonna have to add a few extra dollars.

I know it's a bit confusing.

im wondering how the fees go. i dont think they keep de-ducting.

but someone should prob check. Thus, dont want someone sending 100plus the fee, then if we had to send it to kyle, it would deduct another fee....and there for be short.

maybe we should just try to see if kyle can take the deposits, im sure we can keep in contact with him and try to get everyone situated.
