Precision Billet Turbos

[SimonR32]

that one is defs a 2.8, asking for ya boi vims see if there is a graph for a 6870 on a 26

Think it made over 800rwhp for about 3000rpm which is just silly!

Not sure on a 2.6L, it would shit out power but be fairly laggy. Doesn't vims want a track car?

Id agree with that, some good results happening on 3.0L and 3.2 stroker kits with the 6870 from what im seeing around.

Could be OK for a 2.6 if a small enough rear housing is selected, but it would be a issue up top end when at song. (depending on how hard you pushed it)

What kinda results we talking Gtr psi? I'm getting that turbo for my 3.0 [emoji106]

[GTRPSI]

Pm sent.

[jangles]

26/30

6466

24-25psi

265/35R19 if you want rpm scale

[SiR_RB]

Very very nice mate must come on song strong !

6466 is still my fav turbo, seen results range from 500- to over 600kw

No need for dirty big 6870's and 7175's etc

Haven't got it back yet. Imagine it would push towards 600 with another 3-5psi like other results I've seen.

Definitely a good choice for E85.

The 6870 on my old built 25 made 525ish hp at 28psi compared to the 35R making 475ish at 30psi. On 38psi it's making 676hp but out of injector at 5700rpm. Should go low 700s at 8200rpm.

[GTRPSI]

Do you have a dyno graph or 38psi 2nismo?

I saw a dyno result of a 6870 on a 2.6 today with cams, low 30ish boost, make mid 500'sKw, was as laggy as hell, not very impressed, looked like a slug to drive on the street, nothing then all.

Seen a few like this so far on 2.6's, seems like the 6870 is more towards the extra 15% capacity that a 3.0L or stroker delivers.

Looks like 2.6's run a larger area under the curve on the 6466....

It's a 1100hp turbo on a 2.6L, it was never going to be responsive. I would say my 6262 is right in the sweet spot for a 2.6L non drag application but it's rated at 705hp.

6466 would be a good all rounder for a 2.8L and a 6870 isn't too bad from what I have seen but more towards a drag power band.

I completely agree, 6262 or BW EFR 8374 is the biggest I would go on a real streetcar, up to 3.0L. I wonder how far off the compressor maps the 2.6 is with some of these giants? And I guess I will keep wondering because Precision doesn't need no stinkin' compressor maps!

No point until it has enough injector. Then you'll see the whole thing. Ethanol and a torque converter fill the hole that might otherwise be there with a petrol/manual.

Not a bad effort!
