Awesome!

Looks like that thing hits hard. How is it on the street? The hotside and downpipe swap made a huge difference, good work!

I’ve got the xona 7864 with the new uhf 64mm turbine wheel and tial .82 hotside, can’t wait to test it.

Totally different car! Would have liked to try the uhf rear but you have to buy a supercore which is a joke. The motor could have taken more boost but the turbine wheel design is still causing back pressure so left where its happy.

Comes on very hard and torque steers quite a bit, turned the tyres when cold

Interested to see how yours goes!

I’m curious as to why you went with this particular turbo over a ball bearing FP black

At higher power yes. Ive seen 600+ from a black in stock location at lower boost and stock heads. Hence the question

Silver, someone had to test the xona 7164

Here’s one way to look at it, the largest exhaust housing fp black is offered with is 10cm, the op was having issues with .86 exhaust housing choking and swapped up to a 1.03. If we crunch some numbers 10 cm2 = 0.73 A/R. Although these two turbos share the same compressor wheel, the turbine wheel on the black is a bit smaller 67.3MM Inducer / 58.8MM Exducer for the black and 68/62.2mm for the 7164.

Also FP says this about the black “This combo nearly maxes out the stock location possibilities on this platform.” The 4” inlet paired with the correct sized exhaust housing/turbine really does make a difference, that’s the advantage with rotated setups vs stock location.

Another angle to look at, with the ported heads and 284 custom billet cams this car “gulps” some serious air per combustion event.

Understood that its a bigger housing for back pressure reasons. But now im confused as to why this is making less power on more boost, headwork, and bigger housing than some of the fp blacks. Id expected this turbo to surpass the black especially with headwork and the boost being 5-7 psi higher

hub dynos load the car weird

I bet this thing spools so much faster than an FP black will on the street while making similar power.

+1 I agree with waddlz.

You seen a black make 600whp on 21psi? IMO that must have been a high reading dyno. Or was the map sensor maxed out and it was flatlined and 21.7 or something? I guess who knows, 25 degrees at peak torque and 35-40 degrees up top might do it, and it might do a few other things too

Dyno numbers differ. You never know how much ignition timing is being run by the tuner. Maybe one car is rolling with a tune on the edge of doom, and the other is safe for years to come. So many variables come into play when comparing numbers on the rollers, especially between different dynos.

Now if we could get some 40-100mph times via logs between cars like xlubens old thread (don’t quote me on the mph’s can’t recall) I think that’s a pretty good look at the power a given car is making. Especially for the people that don’t make it to the track or have a local track available.

where were you when I was selling a brand new 7864 for $1800


The Xona rotor turbos are hands down the best for making power and especially reliability. Australian stuff always seems to be built with a much higher degree of quality and knowledge, thank you for sharing your graphs. Would you mind sharing any pictures of your AWIC setup?

In post number 25 the OP says he was wrong it was 28psi.

Mine is an 04 with VSR Motorsports built block. It should be pretty close in specs.

So they both made 600 @ 28psi. It’s pretty much down to who’s dyno reads lower and what’s the curve look like.

Since tgxnavy deleted basically all his stuff and sold the car after that Texas street racing fiasco I think it’s safe to say your never gonna see that particular curve.
