6466 + stroker = loves it. Ignition breaking down over 29 pounds so this was the limit. I think it will do for now. :)

What's redline on this?

Looks like it will want to break things. Lots.

I want one.

Well had the exhaust done, did not pick up much power but it helped where I wanted it, response.

since I changed the Turbo,Cams and Exhaust the car has gone from a pig to drive to being fun, enough up top and good bottom response,street drive :)

Here is the latest Dyno

New Dyno 345.4 KW

Red = Boost off

Blue = Low Boost

Orange = High Boost

Old T78 = 337.9KW

That is a significant different there in where peak torque is made, good job.

Poor old T78 :) Did you end up getting my PM?

Epic result Mitch must be an animal?

That on a 3.4L?

Is it in an R?

She's a beast on the road, i love it more and more each time I drive it.. Yep 3.4L kit in my R34 GTT.

Upped the limiter to 8000 now. Peak power is at around 7400. The whole driveline has been upgraded so here's to hoping it doesn't break anything!

Hi Micheal

Sold the T78 and the bloke is happy, crap it was just about new, well 5 years ago and only 3000Klms on the car since it was installed

No I did not get your PM as it would come in on this Laptop, it does not allow me to gain access to anything other than threads and posts, but better than nothing. If you would like get me as TT350GT I can access everything on my PC.

I have caught the Mod bug and going to have the RB30/Nitto 3.2 Stroker kit shoved into it, keeping the PT6262 may get a bigger back housing and go for response, it is a DD and I want it to be what I thought it was when I bought it.

I have to say that since the last modifications I got to love it but need more and might have to come out of retirement to pay for it,bloody cars ,haha

Haha, that's great :D can't wait to see how it turns out!

does anyone know if precision will release a gen 2 6766 or a tubo slightly bigger than a 67 but still retain twin scroll, as anything larger than a 67 seems to be only able to be bought with a single entry rear housing.

7175? Or FP Super94 :P

OK so the Precision PT6870 CEA is out now - from the initial testing it is serious serious serious business, ultra impressive.

See here: http://www.supraforums.com/forum/showthread.php?859938-PTE-6870-CEA-GEN2-Test-Results-by-Sound-Performance

PT7275 versus PT6870 (all testing on the same engine setup):

7275div981010whpvs6870811059whp_zps5ba3a

PT6766 versus PT6870

676681949whpvs6870811059whp_zpsb7426611.

Spool comparison:

PT6870SpoolComparison_zpsa6432d6b.jpg

Those dyno results are all "max effort" on a good motor and high ethanol percentages, so likely to do them all justice. The spool and the relative power versus the 6766 and 7275 impress the hell out of me, nuts.

Yep, quite interesting. All results were impressive, though that particularly made me think of the GTX3067R result someone on here got.

Not sure if referring to my GTX3067 result, or typo, but nonetheless also found the results of 0.81 v 0.96 very interesting.

Below quote from the original page in particular:

The .96 A/R only added lag and if you reference the boost spool comparison below, we also weren't able to see as much boost with the duty cycle all-in. This tells us that we were at a limitation of the compressor wheel flow itself and not because of back pressure.

Not always beneficial to go larger A/R it seems.

Anyways, sorry to digress from subject of thread. Thanks Lithium for posting above info.

Keen to max out a 6870! Hopefully they release divided housings for them sometime soon. Certainly looks good on paper, gotta love those GST yankee figures as always :)

6766 rated to 935hp, makes 949hp atw.

Yeah those numbers seemed high for a 6766 on a Mustang, though I am still shocked that people are taking hp ratings as some kind of gospel. How much did you make atw on your old GT3076R? And what are GT3076Rs rated at?

The 6870 is certainly looking the goods, no matter how you slice it. Would have loved to have seen FPs Super94/99s on more things - they are in T4 twin scroll and imho until this came along the best thing since sliced bread for the ">6766 power without going BIG frame".

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
