Garrett -5S Vs -10S Or Other (Tuned On E85)

[Daz]

Hi people,

I tried searching for the -5 Vs -10 thread however I could not find it, this topic may be a little different as the car is running on e85.

Key considerations

- Motor is a fully built Rb 26 (26 bottom end)

- 262 in/ex cams

- Car is built for street/drag

- The car made 420 rwkws on 20 psi, we tried raising the boost however there was no power gain (I believe turbo’s were out of puff)

- Fuel system is more than capable of 500+ kws

My questions are

1. How much laggier would -10s be compared to -5s (running e85 can put more timing into it)

2. Is there an in-between turbo or any other turbo suggestions that will get me up to 500rwks?? (please keep in mind that this is a street car and needs to be low mounts)

Attached is my current dyno graph

Thanks

Daz

There you go.

Quick answer. If it's a 2.6 don't bother. It will become a nugget.

Gav made 460 + on the baby -5's. It's just a matter of setup.

Question answered, close thread

For a twin set up chasing that power I wouldn't use -10s, it will just be a laggy peice of crap.. Especially on 2.6.

You probs won't make 500 on -5s but It's probs your best option if you wanna make big power on twin low mounts..

Unless you wanna run a pair of the new GTX turbos.. You should do that

I've actually been asked for a test guinea pig for the GTX2863 in pair format on a GTR. Who wants to volunteer?

[Piggaz]

If only you weren't 1000 kms away!

-10's are notorious for surging & shuffling not to mention an awful option for street duties. HKS 2530's are slightly bigger than -5's but nowhere near as big as -10's.

I'll drop mine off on Friday

There was no indication of distance limitations. Pricing would be very appropriate but testing would need to be reported comparitively

What would you like to know?

Comparative dyno results vs -5's on exactly the same setup and roughly the same time of year for both dyno runs. Also a non-WA dyno result would be preferred

[R31Nismoid]

lol at least it's comparative if it's on the same dyno

Anyway results are in the GTX286X thread:

Do it Piggaz

[Piggaz]

I don't need you egging me on Joey! haha.

It wouldn't be fair anyway. New head and cams!

[N1GTR]

He won't, he is being a big softy, "450awkw will be enough" to quote him

[N1GTR]

Here he is.

Try -5's first then do the swap to GTX5's. Winner.

[GTR_JOEY]

Haha "450 is enough" mean while yas a trying to convince me to buy a 1000hp precision single...

It's either the GTX or single Paul, decision time

[Piggaz]

At my wallets arse raping.

No!

Lol

Dan, what's involved in being the test dummy?

Bahaha that didn't take much convincing

Someone is already interested in trying them but I could ask for a second pair maybe. Still waiting for info back to confirm the comp cover is going to fit against the standard manifold
