Do you forsee the car needing a Nitrous kit in order to spool the nicely large turbine on that?

Also, question about the design approach to the Manifold. I was looking at the runner that's going to Cyl 1 (going from left to right). I was thinking why not make the runner on Cyl 1 go to Cyl 2 instead, and the Cyl 2 runner go to Cyl 1?

thats not what i really expected the manifold to look like for a set up like this.

To each is own......

Whats it supposed to look like?

Manifolds are not designed based on looks but function

the product is too raw, i'll make my opinion when its done.. i didnt like the version 2.1 at first but when they came out, its a different story.. and looks should not come first before function

Looks very nice, positioning that monster must have been hell. Welds look excellent as well as the outside of the collector. Hope you have a brace or some extended exhaust studs *LOL* That baby looks heavy

because its a twinscroll setup. the flow of cylinders 1 and 4 are separated from 2 and 3.


this should help explain...


"The concept is to DIVIDE or separate the cylinders whose cycles interfere with one another to best utilize the engine's exhaust pulse energy.

For example, on a four-cylinder engine with firing order 1-3-4-2, cylinder #1 is ending its expansion stroke and opening its exhaust valve while cylinder #2 still has its exhaust valve open (cylinder #2 is in its overlap period). In an undivided exhaust manifold, this pressure pulse from cylinder #1's exhaust blowdown event is much more likely to contaminate cylinder #2 with high pressure exhaust gas. Not only does this hurt cylinder #2's ability to breathe properly, but this pulse energy would have been better utilized in the turbine.

The proper grouping for this engine is to keep complementary cylinders grouped together-- #1 and #4 are complementary; as are cylinders #2 and #3. "

Beat me to it, But a much better description than I was going with haha.

So, the manifolds Flow tested?

rhythmnsmoke

So, are you saying the extra length on the pipe to Cyl 1 is suppose to help with grouping it together with #4? Then what's the point of having equal length? And with our motor, does it actually follow that firing pattern (1-3-4-2)?

DAMN THAT SUCKER IS HUGE!

rhythm...Todd's new mani's look off cause of that first straight runner...makes it look like it's not EL from the most commong (top down) view...but looking at it from the side, you can see that the other 3 runners are actually longer then they look, so they are actually EL.

What kinda coating is going on that mani? I still prefer black...

Ok...im a lil late seeing this thread but...WOW that is beautiful! THE TURBO LOOKS ALMOST AS BIG AS THE ENGINE! Cant wait to see whose getting this monster and what it can do...PROPs Todd for never sleeping!

rhythmnsmoke

Were are side view pics located? Did you see this in person?


Also still curious to know if Todd flow tested it, as well as what means is the owner going to use to spool up the 42R.

Mr_Meaty

I have not seen this particular one in person, but the way the runners are going are similar to his version 2.1 mani, like the twin scroll dual WG setup he has. There are some side views of that somewhere.

And I do beleive Todd mentioned that his manis were flow tested, but I can't answer that with any certianty...sorry.

prolly this one is not yet tested but yeah its almost similar to the 2.1, i have side views on my thread

krazylowgsx

I'm pretty sure the owner is just going to use his crazy built motor to spool that monster! he doesnt like nitrous

What is being used for cooling Todd? OEM fans are probably outta the question and odds are you fabbed a working fan set-up. FYI I'm curious since I have that current problem (overheating)

There is no need for me to flow test it....

I was part of a "study" a few years ago when we did a test on manifold design.

All I will tell you at this time is that this manifold with these size runners will flow allot more air than a GT4294R can throw at it.........allot more. Granted there is a sweet spot, but this setup wont make it there for a bit.

Why do you think its going to be so hard to spool?

Don't always judge a book by its cover......just cause its big doesn't mean when paired with a few key components it wont get up and going.

Plus its pretty obvious its not really a "street" car set-up.

Yes the car will be driven on the street, hence why I had to make it work with the factory radiator, and AC. But it wont shine there.

Todd

todd that is beautiful end of story cant wait to see mine will it look like kdogs? basik manifold or a little different for the xb2? you make the sweetest manifolds

rhythmnsmoke

I'm not big on the "just take my word for it" type answer. Are any of the rest of your manifolds flow tested?

Why do you think I was saying it was going to be hard to spool? Obviously it's going to lag more than a standard setup. I was wondering if there were going to means to make it spool faster, hence the question. No implication bro.


Again, hence the reason why I asked the question. Here, let me rephrase..."What's coupling with the turbo to make it shine"?

krazylowgsx

you just dont quit do you travis.. lol. obviously this turbo isn't goin to spool as fast as say.. a 16g but sometime you have to make sacrifices to obtain a goal. if 300whp was the goal here, I'm sure the guy would have picked a more logical turbo.. if turbo spool was a concern, again... there's a better choice. but if I'm correct, this guy is doing an all out build.. very little will remain stock.

Todd's manifolds flow tested? lmao.. have you seen everyone roses manis? the runners on that _____ are 1.5"... do you think there's restriction there? Todd knows what he's doing, and alot of the cars out there with his kit are making more power than any other kit on the market. idk... maybe I'm wrong. Todd... maybe you should bolt that 4294R to a log manifold!
