1UZ twin turbo

[love ke70]

I think Oldcorollas mathematically proved 2 SC14's wouldn't do shit

I think it was 5psi by 4000rpm, and causing a restriction by 6000rpm

just consideing this, why is the case that 2 sc14's only make 5psi on a 1UZ. when each bank is 2litres, and they came off a 2 litre motor?

might do a search, see what i find

Really?
I put the numbers into EAP and got some nice results?

well he better tell the guy that runs two sc14's joined together on top of the 1uz in a open wheeler that revs to 10k and has had the setup for many years and its might fast, that he is mathematically wrong!
He got the rear and front housings machined so they are joind together and run of the one pulley.
He had pretty good lap times of Oran park with the above setup in club events from memory.

Are they modified in any other way ?
I would have guessed they would be more of a drain at revs that high, unless they are near useless at the low end instead.

Sorry i should have edited instead!
Remmeber, a 1uz is 4 litres and a sc14 is used on a 2 litre engine so two sc14's will do close to the same job as one on a 1ggze with standard pulleys and more with a diffrent pulley!
Im sure oldrolla wouldnt have got the maths that wrong.



edit, forgot the NT of wouldnt.

I dont know much about it as the guy is a car salesman so a bit of a tool!
the pulley seemed small so id imagine its set for the higher revs.
As far as i could see it was a great setup for the money.

Stock 1UZ:


SC Setup:


Result:


That is with the boost limited at 8 PSI and a smallish TB.
Oh, and a 25% (small) efficient intercooler.

[edit]
No boost limit and huge TB:

Wrong!

ten char

[byteme]

what is ??

[kingmick]

turbo cheaper and easyer! sorry i should have said that!

[byteme]

*waits for barage of oncoming neg rep*

yeh i spose i shouldnt have said that, but then again its been done quite a few times, so it'd be easier finding the parts to get it completed. nothings easy and cheap when it comes to cars

[MWP]

Yup, i disagree too.
SC14s will be cheaper to setup than turbos delivering the same high end HP/TQ figures.
SC's will be better too... no boost lag.

[byteme]

fixed, now no one knows what i said.
what are the sc14 from?

[CrUZida]

Sorry, I was thinking of 2 SC14's, but it was actually one SC14 running at double speed that Stu did the maths for.

[CrUZida]

Twin SC14's will look shit though.
Much better off with a single M90.

Easier to plumb, and not much more expensive for initial purchase.
