Can we talk about triples?

Ben Miller is running triples this year too...... That is all I know :gag:

AAAAAAAAAAAAAAAAAAHHHHHHHHHHHHH

2 stages, 3 chargers, 2 Primaries, 1 secondary.


Like a pair of S480's and a single S465.


Not 3 stages, even I know that isnt a good idea.

Two s480's??? Wow, that would be a lot of air. I was looking at doing two hx-35's as it is a lot cheaper then a single S480 / GT4708, and they move about the same amount of air (both ~120lbs/min). My problem is that I don't have near enough fuel for that. I need something more like a pair of GT28's.

I have also been thinking about mismatching the primary turbo's like have one T3 60trim, and one Hx-35. I think that combo would still be a little big for what I need but getting close (~85lbs/min). Regardless I will try a few different setups, mostly just because I can and I like to see what they do.


Anyway back to a pair of s480's (~240lbs/min) I would have to say even an S510 would be a little small as a secondary (depending on the config) Maybe an HX82? or a GT55? Regardless sounds like a mod puller setup to me. :charger:
 
I was just thinking out loud.

I have no clue what the sizing would be for a 1200 truck
 
It not the number of turbochargers, but the tuning that is killing parts.
Billet block are here to stay, there are too many out there to go back.
Billet blocks are not breaking, but being broken. Cast blocks are getting blown the f up.
One thing is for sure though. Divided, our class will fail. Pretty soon no organization will want us because of low attendance numbers, and the fans wont back us up because we can't get down the track.
 
it would be cool, but i think it would be more benificial on a V type engine, run one turbo per head of equal size, feeding a large tubo, i guess if you had a manifold for a cummins that was two piece, matched the turbo's for 3 cylinders, and then found one that would work well for the third turbo, probably work pretty well, but im just a retarded ferd guy!

Your thinking of it backwards to what is being discussed here. :kick:

Cool looking setup... But still backwards from what is being discussed.
 
I don,t think they are running two smaller primarys to make up for one big one,they are running two big primarys because there is not a big enough single for the air they want.So on a street ap it would be kind of pointless.

how's it back wards? you thinking of one large on right off the manifold and two smaller ones driven off of the large one?

Yes.

As discussed previously 2 hx35's = ~ 1 S480

So a setup like an Silver 66 over an S480, you substitute the S480 for a pair of HX-35's in parallel.

Or in the case of a MOD puller you substitute one of those huge hc5a's for a pair of S480's.

Yes, 1 manifold charger and 2 atmospheric chargers, hence the 2 stacks

I would think a single that flows the CFM they want is made, maybe there are packaging reasons they dont run them.

What if the 2 primaries arent equaly sized?

I know a set of twins will work for any street truck, Im just wondering if it could be done without a loss in power on an application that didnt really need it.


dvst8r and DISTURBED have it correct on what Im talking about. The Hamilton setup is the reverse of what Im talking about.

Any sizes on those turbos? If those are 66mm's over something like an 80mm, its pretty pointless as the two smaller ones will flow the same or more as the big one, which means zero compression compounding, and a ton of lag.

I'd think something like 3 HX35's, two feeding one could be a cheap and effective setup.

That was my thought as well, after seeing an HC5A in person, even with a first gen I am not sure where I could put it, but I could probably figure out a place for a couple of S480's (not that my truck will ever get to that level)

That has been my other question that no one (as of yet) can give me a "tried it" answer. I am building a set right now that consists of:

-HE351 manifold charger (with external gate) -> T3 60 trim in parallel with an HX-35

Now I have no idea how well, or if it will work at all, but I am going to try it anyway. :bang

Maybe with a big external gate, as I think the manifold HX-35 would choke out pretty quick as it would be like running an HX-35 over an S480.
 
The more I think about it you would almost have to run an external gate on any double primary setup.

Maybe a 1000hp truck would need a 66mm manifold charger and and a pair of 71mm's for secondaries with tight housings. Like a .8 on the primaries. Have one of the primaries on a wastegate to come on when the other gets to say 25psi. Run a large 1-way valve on the pressure side of it?

Just a thought....
