twinturbo 4efte...

[HYBRID]

in all honesty.. the best way is to keep things simple.. strap on one fucking turbo, let it spool and enjoy the loss of traction lol :haha:

apart from that, if ur making a project for say uni, then yes id give it a go, for a normal day to day car (or track/drag car) id seriously stick to what is the simplest way of compressing air into our wee 1331cc engine lol..

Yeah man, the cost involved with a bigish VNT turbo will be huge. KISS, keep it simple stupid hahaha

lol u just reminded me about KISS haha.. damn that was a long time ago when i was doing my IT diploma lol.. Keep it simple, straightforward !! haha... very wise words i must say lol..

All we seamed to learn at college was things like that, remember another one Assume, to assume it to make an ass out of you and me. Instructor used that one alot and KISS.

 

[richglanzav]

will somebody ban that retard starletGT or w.e hes called, his posts depress me. i mean why cant ya have full boost by 3000rpm on a ct9 are u a total moron or what.

seriously cool project here, any idea of the power?

 

[Paul_JJ]

The project is very interesting! Looking at the manifold I imagined how hot it gets and that the hot pipe right on top of it - so basically it is hot anyway, but gets all the heat of the manifold on top of that, thus making a tiny intercooler do an extremely hard work. But yeah the idea is pretty good, but why don't go for a big front mount? having 2 turbo's I assume would give more performance and small lag, possibly running such low boost wouldn't put so much pressure on the turbo and won't make so much heat as if it was a big turbo!
What's the BHP like on the car???

 

[TheStarletGT]

I will not accept the fact that the person said he could get optimal boost by 3000rpm using 2 standard turbos at the same time. Single turbo, probably yeah, but two, i dont think so.

If you combine the exhuast housings, it would like be equivalent to a t3 turbo maybe. Plus each turbo in this application is powered by only two cylinders. There is no way this engine is allowing 2 CT9 turbos to spin super efficient. If they were two td01 or td02 turbos, i will than belive it.

What if the engine was built for very high compression, then it might work

you sir need to sell your gt and ride the bus

 

[pc18]

every post he makes is drivel. there should be a permanent warning in his sig saying "disregard the above post" i think hes worse than cal was.

 

[TheStarletGT]

What, you people cant handle the truth. tell the OP to do a drag race down the quater mile and see if the car does 11's. Or do a dyno run and see if it makes 230kws. No matter how bad you people refuse my facts i'm providing, your still gonna get it. Stop being sooks and accept the scientific proof. I dont give a shet if i get banned, big flop.

The scale has to be correct.

RB26 with two small size turbos
2JZE with two smaller turbos

Its like as if the RB and 2JZ came factory with GT30 turbos. For a 4EFTE to be a successfully branded twin turbo engine/setup, it must be super efficient with properly sized turbos. Two CT9 turbos is not the correct scale. As a knobhead mentioned earlier, he sees 3000rpm turbo bost with a single CT9, so imagine two, get it, do i have to draw you people a picture.

Just accept it, would you say its perfectly normal to run 1 CT9 turbo off 2 cylinders, this setup is equivalent of running 2 engines, 1 turbo per 2 cylinders.

1 CT9 at 3000rpm on a 4 cylinder engine
1 CT9 on a 2 cylinder engine

Dont care how bad you people think how magnificient this setup is, you may suck up to the OP as much as you want, fact is, its a waste of time, not worth the time or effort.

^^Amen!!

 

[TheStarletGT]

Congratulations in the setup.


All i want to say is that i have a TD04L setup with supporting mods and i have no lag. Its instantly boosting. If i were to choose between a single turbo TD04L setup and a twin CT9 setup, i will choose the TD setup blindfolded anyday.

 

[jpecc]

twincyturbine ct9's... did quite well little less lag for a 1.3 banger.. anyway it did work single or 2 turbo it still did work.. heheh...

rumor has it that f1 cars are goin 1.5l on twinturbo setup 4cylinder by 2013 dunno if this is true???

thanks again toyotagtturbo and more power ....

 

[AdamB]

I think they are just going 1.5l with single variable vane turbocharger, but only rev'ing to 9 or 10,000rpm. Still pushing 800bhp, with the Kers system doubling the kW power per lap.

^^^^^ This.

Back in the 80's when Turbos were in F1, they only had twin turbo set ups on 6 cylinder cars. The two engines that were 4 cylinder, were Hart and BMW, they only used single turbos. I'm pretty sure BMW moved to a V6 by the end, not sure.

Awesome documentary on it here:

After about 20 minutes it shows you the configurations of each engine.

I just have to revive this thread, what happened??

Basically Skalabala,

Starlet Sams Mum, spoke to bernie eccelstone, told him about this thread on tgtt.com and BOOM

Next season F1 will be small displacement Turbo engines all over again.

Sorted

nice tread this but loads of bull that 2 smal turbos dont work they do but its the way there plumbed in that has to be right like in them photos 2 turbos on the exhaust feedin the 1 intake manifold is wrong wont work well like that

when we did it more than 10years ago we used the 2 stock turbos and 2 carbs and made a exhaust mani x2 for 1and2 , and 3and 4 made 2 intake manis 1 for 1/2and a carb bolted to it then the same for 3/4 and it worked great on boost

the only problem we had we could not get her to idle right attal to much feul of boost

if we where to do it again i would swap to injectors that would sort the isseu
