6766 Cea Billet Turbo On A Rb26

[Gtir-keiron]

Hey all im about to put my combo into the car going to run pump fuel atm as im 3 hours from the nearest e85 servo!

Any how my combo is

forged rb26

alot of port work done

276 custom grind cams

VCT

6 boost manifold divided

6766 cea divided .84 rear

45 mm turbosmart gate

Just can not find any info on these turbos on a rb26 like dyno sheets or hp figures id like to know what im getting my self into and where i should be on pump fuel hp wise at the wheels in my gtr.

Thx for any help

[The Dan]

550hp on pump 98

[Weapon X]

I have a 2.8 with a 6766

733hp on our 93 oct on 2 wheels

23.5 psi

I have a 1.15 AR

Wow, that is good power for pump gas - but that also looks really quite laggy on a 2.8litre!

[GTScotT]

Could be the 1.15 rear end, its a big exhaust wheel as it is so the need for the largest possible housing is debatable.

To OP: are you sure you have enough gate for that setup? I would have wanted 50mm at minimum for a single gate on that setup, I wouldnt be scared of a 60mm either.

[The Dan]

Shit I'd be interested to know the rest of the setup. 93 octane and 700+ HP is.....unheard of?

We normally see 650 on E85 on 26-28psi

[GTScotT]

Thats a 930hp turbo. These things are known to punch above their weight, are you sure E85 would only see 650?

Correct me if I am wrong but PJ has gone 850whp from a similarly sized unit from a 2L on E85?

im not suggesting 730 on pump is whats to be expected, but A: were talking US pump 93, not skip land pump 98 and B: were talking a US result. US results are always higher than ours, no matter what.

[Lithium]

700+whp on US-93oct sounds like heaps alright, dyno discrepancy aside (assuming 10% lower reading that is still not far short of 500kw) - would love to know more about the car.

On the flipside, 650whp on 26-28psi - that doesn't sound that huge if talking about a fairly serious setup (using a PT6766 to its potential is pretty serious by my reckoning). What kind of setups are you talking there? A mate of mine's stock stroke RB26 makes 865hp @ 4hubs on 22psi running on E85, which by my reckoning should equate to at least 770awhp/575kw on a Dyno Dynamics dyno.

I may be thinking about a different turbo. I'll ask the customer. Still fairly new to identifying PT's

[SS8_Gohan]

yeah i thought US 93 was roughly equivalent to our 98?

[The Dan]

I can't see he's from the US. This mobile version sucks the wang.

723hp on 98 is still a big number. What's the go with that?

[methz]

i got a mate with a 2jz made over 700 at wheels on bp98? its doable...

[SS8_Gohan]

as for the US results, well it's about 540rwkw.... so given US results are always very happy (or ours are conservative??) if it's say 10% out, that's high 400's... have no idea if that's realistic for that setup for not.

randomly found this on a Dutch tuning companies site - PT6765 - 611kw. - not sure if fly wheel conversion or at the wheels.

EDIT: never mind, looking at the other results, it looks like they've done some calc to guestimate the engine power... not very useful then...

US spec 93 is better than our 98 for sure. I would put our 98 closer to US 91, but a little better. There is no direct comparison.

As has been said, 700+ is a big number for pump fuel. Yet im not surprised. Its likely to be calculated engine HP, plus the level of discrepancy that we are used to seeing.

When I saw the result I gauged 450rwkw, which is a walk in the park for a 6766, the only questionable thing is US pump 93 and if its good enough to support the number.

I would realy like to find one of your guys dynos here in the states because I'd run my car on it Happily to see this big diiference.

Has this ever been tried down there?? Any Dyno Jets around?

[Lithium]

In NZ we have Dyno Dynamics, Dynojets, and mainly Dynapacks - I have considered doing comparisons between those 3 though the results I have seen from the bunch seem to have Dynojets reading marginally lower than the Dynapacks and basically add 8%-12% to Dyno Dynamics results to get Dynojet/Dynapack equivalent results.

[Weapon X]

We are putting car on my Dyno Jet and on a Mustang in the same day soon just for fun to end the what ifs and I thinks around here will be fun just to see the difference.

I post up the findings.

Don't know of anyone in NZ or Oz using a Mustang, but the general consensus seems to be they read nearly as low as a Dyno Dynamics

Low compared to what?

[Lithium]

Mustang dynos don't seem to read quite as low as Dyno Dynamics dynos with "typical" setups, assuming you don't count the way the Brits tend to set up DD dynos (to estimate Flywheel).

Will be interesting to see the DD vs Mustang comparison
