Question About Twins

[RabbitJockey]

i think it should run alright, spool of a ko3, flow of a k24, might have to play around with how the wastegates are set up because you are still limited to what the k24 can flow.  if your ko3 is set at say 10psi, and your k24 is also set to 10 psi, then when they are both spooled, the engine should be seeing a pretty efficient and fast spooling ~27psi (if my math is right.)  and really i don't think you can go much higher on either turbos boost setting with out exceeding the flow and efficiency of the k24.  especially since it's on a tdi and they move quite a bit more air.

the math (10psilpboost+14.7ambient)*((10psihpboost+14.7ambient)/14.7))=41.5psi absolute pressure or 26.8 psi boost

Yeah the vnt is a lot newer flows same amount of air more efficiently from a smaller wheel but I still think k24 would flow a bit more since k24 is 38 trim so the 40 trim t3 map would be pretty similar. The outer appearance is not always a good indicator of its flow.  I think k26 is good to try as a second turbo really tho the dodge turbo u have is pretty comparable it and maybe a better option. But ur gonna be limited to low 200s for hp which is good really

the Chry T3 turbo? its CONSIDERABLY bigger than the VW/pug T3s i have.. would it perform better than the K26?

the K26 has no wastegate, the T3 has a wastegate port, but i guess you dont NEED to run it..

i think itd be better than k26, but they look to be pretty similar in flow over all, the t3 does better at higher pressure ratios tho, but that doesn't matter if you are doing compounds.  the chrysler turbo is mostly just bigger on the exhaust side in comparison to the pug turbo.  i think they are kind of medium sized turbos for doing a compound tho.

but what i was saying before was that in compound the spool would be faster than with just the smaller turbo by itself

This setup is in a Toyota pickup truck.  We don't plan on running more than 26psi so we should be good to go.  We also chose the k03 because it is a heavier vehicle and quick spool is very important.

. Has it been driven yet I'm curious how it runs

I hope you don't plan on much more than 18 psi with that turbo..it week never home up to 26 psi

what turbo? the K03? what about if it was in a compound tho? if both turbos are only making 10psi, then both are WELL WITHIN there efficiency limits..

because, obviously, if the K03 is being fed with 18psi boost, there will be more than 18psi coming out of it..

as long as the wastegate is big enough to allow the hot side to NOT be a restriction, i could see this setup working AMAZINGLY..

but i dont think the STOCK K03 wastegate will bypass enough exhaust to relieve the restriction of the hot side housing..

the exhaust side is the only thing i could see being a problem too, but it sounds like he will be monitoring all of that.

yes, he definitely has it covered.. if its a problem, i see it being corrected quickly..

Such kind words R.O.R.  Are you feeling okay?

no, i just know you wouldnt jump in with both feet without having some sort of gauges to monitor everything.. i know you arent looking at lifting the head with this turbo setup..

so wahts the word

Last night would have been the first test drive but we have a coolant leak at the water pump.   We had just finished all the other plumbing, power steering, intercooler, and we're hooked up to the fuel tank now.  The last thing we did was add antifreeze and discovered our first leak.  We'll take care of that this week and the first real test drive will be this weekend.

So I have a small update.  

We have a couple of test drives on the truck now.  No exhaust yet other than a stack coming out of the k24 pointing straight up.  I have no real numbers yet but emps are reasonable, roughly 30 psi under load.  Seems to be a good combo for a truck.  What surprised me is how much boost it builds just by bringing the revs up.  It makes over 5 psi at 2000 rpm with no load and both turbos are building pressure by 2500.  My only real conclusion so far is that it has ZERO turbo lag.  Absolute blast to drive.   Time for some exhaust, put the hood on and get some more runs in!

so, this is a K14/24 setup?

maybe my 24/26 setup isnt such a bad idea after all.. because im not looking for boost at idle, just lots of boost once it picks up, and all while not making one turbo strain..

GREAT JOB!!!

Can we see some pics 410?
