Idaho BS thread in the PNW

Correction it was free.

 

I thought about an add a leaf. I already have the All Pro Standards, def should have gotten the expos. and Thanks Lisa, I was already in the process of reading that thread when I came back to check this one. Ill probably have to go 3 when I get my rear bumper.

 

Correct. 2jz aren't parallel. They are sequential. Smaller and bigger turbo.

Still best way to go is 1 big single. Amd 1100? Lol that's nothing man. Plenty out there at 1200-1400 now

 

i think the 2nd gens are twice the price.

 

I don't think adding an Aal to the allpros is possible..thing they are designed a bit different..or maybe I'm wrong..

Either way I'd just save for expos maybe..

 

Anything over 500hp is useless.

 

Yep. Agreed. But they are lots of supra Dyno queens at 1400hp

 

and diesels with over 2000Ft/Tq

 

I have the expos on my taco i think they do great.

So answere me this if one bigger turbo is the way to go then Y are all those diesels pushing over 2000ftlb on the dyno running sequential turbos???

Its not usless power it's great for killing tires. I have a friend with an AWD DSM pushing 700 horse it breaks almost every time he takes it out but he can take a hyboosa in a 100 yard race.

 

Yeah,I should have bought them instead. They woul be great but snce I dint looks like I might be frankensteining my leaf pack.

 

If you want to make peak numbers, then I would think one big one would be the way to go, but I would think that running a small one followed by a big one would give you a better edge when racing assuming you can keep traction. The exception would be if you could spool that single big turbo really good before launch, then one might be a better way to go.

 

Different engines yes but in my mind boost is boost and if you have a big turbo for top end and a little turbo for bottom end then i think thats better. Just trying to learn/make sense of the one bigger turbo.

 

I have a few friends that work for BullyDog and they run Small Big turbos and one guy is pushing 120 lb of boost doing so. now i wouldn't go that far with a 2jz but that same idea is what i base having twins off of.

 

Damn that's a lot of boost!!

Why not just run one of those procharger things? The turbo that has the S/C pulley on it for the low end

EDIT: Hmm... I can't see to find it. I thought they were made by procharger, maybe I'm crazy. I can't remember where I have heard of such a thing...

Re-Edit: Ah, I think I was confusing the word "Pro" with the word "Twin". Twincharger was what I was looking for. This is close, haha:


This is from a VW Golf GT, I guess.

 

Not gonna lie that looks like a cluster. URD makes a super charger using a the compressor wheel of a turbo and it's belt driven. paxton makes them as well.

 

Looks pretty clean to me




URD's is a basically just an S/C though. This makes instant boost like an S/C and then when there is enough exhaust it makes peak boost like a turbo.

It wouldn't be as efficient as just a turbo since you have the S/C pulley drag, but again, it should make boost way faster than a turbo.

 

There's looks like it knows about when the Turbo will start to outperform the S/C and opens the bypass and clutches the S/C, so it is basically switching between the S/C and the Turbo.

I was imagining a turbo, that is setup just like a turbo but also has a pulley on the front of it, so it runs off the crankshaft until the exhaust starts to drive it faster than the crank and have the pulley on a clutch so it won't slow the turbo down (kind of like how you can stop pedaling on a bike and the tire can keep spinning without the pedals moving)

 

I consider it a cluster cuz of all the electronics involed in running the two properly. i like just a SC on my truck and when i have a supra i want twins on it. and ill build it up to be fast but not so fast i have to rebuild it all the time.

 

I see. If my idea is doable (I'm guessing it isn't if it hasn't already been done) That wouldn't be much different than installing a turbo in the first place and would only require an extra pulley and belt over a turbo.

 

I have seen it done on a supra. But it's really really hard. Not a lot of engine space mostly but it just tent
Des to work better if you have one larger effecting turbo on a small gas motor. 2jzs are only 3.0l motors.

Correct. Denials work much different obviously but they also are better for turbos as they push out a lot of exhaust.

I love how the Frankenstein term has caught on haha

Kinda already answered this. But it can work quite well. You have to be very picky on turbo choice. Plus cost is a big part of it.

But yes it can work better. Actually an even better way is to twin charge. Run a supercharger and a turbo. That's the best way to obtain low end boost really.

While the one big turbo will move the power band to high rpms, you'll usually get more power as you can actually fully utilize the turbo. And on a 2jz that's not a problem. Get some new cams and some valve work and head work and it'll rev to 9 grand no problem.

Actually it doesn't..well it can I guess depending on the size of pipe after the first turbo. You would tie the waste gate and turbos exhaust into the inlet exhaust port on the second turbo so you'd still get most of the exhaust. But the first turbo might not run as effient as it could cause you might have to use a smaller exhaust pipe to make it all fit.

Actually it's quite nice it goes along with the twin charger principal. A belt starts the turbo off so you get boost at low end good but as soon as the exhaust starts to really push through the belt no longer spins the turbo. Instead the exhaust takes over and spools it up to full boost for high end power.
