Chris is the man!

@josoup this is your car

 

'pretty basic street car'.

'922rwhp'.

The future is wild and we're living in it. 😆
Amazing numbers for a turbo of that size!

 

Chris is the goat!!

 

Thanks for sharing Chris.
What kind of exhaust manifold is being used?

 

Virtual works racing single gate

 

Incredible work guys - just saw the video on IG !

 

900+ HP from 5400-7100 RPM. Wow!

Goddamn! That has to be a pant shitter on the street, tires fighting for their lives. Wonder what same setup with a Next Gen 6466 would be like? Same power but earlier response?

 

Based on what I've seen from friends like Chris tuning the larger Next Gen offerings - likely identical or faster spool with another 100-150whp.

 

Sick setup

 

Bro 😎

 

That's wassssssup!!!!

 

Late to the party but I have to say AMAZING work @Patrick94TT and @cwtt.


Ken.

 

Thanks Ken! This was a fun car to build.

 

Would love to see how a G or EFR turbo does in the same size.

 

A Garrett turbo would never let us push it this hard. Ask us how we know 😂

 

I tuned a pretty basic street car tonight. I really like these precision turbos. This was the older generation precision and it still made impressive power for such a small turbo.
I personally like seeing the drvabilty gains from the VVTi.

PBR built short block @Patrick94TT
Motec M130
10:1 3.0
NA VVTi fully built head with BC S3 cams (272)
Gen 2 6466
SD RMR intake manifold
T56
FIC 1650
2 fuel pumps
R35 coils

Tuned by myself @cwboosted on IG

44psi 100% wg duty cycle falling to 30psi. This is all she has.

80% pump ethanol

This is VVTi only tuning (no fuel, ignition or boost changed): Note wastegate has boost creep on the wastegate, but it was consistent.

Nice numbers and great street turbo

 

Wow, drivability is going to be awesome.

44psi falling to 30psi, back pressure stacking up? I'd be curious to see EGTs or pressure ratio, if those sensors are present

 

This is a good point. The customer lives in a coastal beach town out here that’s kinda known for pulling modified cars over so he requested we build an exhaust for him that would quiet it down a bit. We did a 3” to 3.5” right off the back of the turbo (.96a/r) for a “full” 3.5” downpipe, to 3.5” midpipe, to a 3.5” exhaust that had a Vibrant resonator as well as a Vibrant muffler from the axle back. I think if we didn’t have this restriction it would have allowed it to breathe up top a bit more.

 

Curious on the Garret as well. So far my gen1 6266 performs really good, but those next gen turbos are insane. Patrick and Chris, how do the nextgen perform on pumpgas? Do you see a difference in spool and power as well or only at high boost/E85 levels?

 

I haven't seen anything impressive from nextgen compared to Gen2 yet. Done a back to back on 6870 and was identical. Maybe at some ridiculous boost theres a gain, but not something you wanna be at for a long period of time.

 

I don’t want to muddy this thread with discussion about Garrett turbo failures but if someone wants to start us off fresh with a new thread I’d be happy to share my experience with those dogshit turbos.

Also @Mike2JZ I think there’s a thread elsewhere discussing in general the new Precision Next Gen turbos and the comparisons with their Gen 2 counterparts but if there’s isn’t maybe we can start one as well. At this point Chris @cwtt and I have tested basically every “normal” Next Gen turbo out (6266, 6466, 6870, 7275, 8085, 8685) on multiple different displacement 2JZ with both VVTi and nonVVTi and every single time we have seen significant improvement. The 6870 might have been the only turbo we weren’t overly impressed by. The 70 wheel is probably just out of efficiency at that point.

Well, this is having me rethink picking up a 6670 in favor of a Next Gen 6466 with the "H" cover.
What was the block build parts list?

If you were in FL, I would definitely be at your shop with my car Patrick!

 

What has happened in recent years? I remember the days of Garrett turbos taking anything you could throw at them while PTE made great boat anchors after a few pulls

 

I remember that too. Seemed like Precision used to put all their budget into advertising and little into R&D. They have certainly come a long way. I do run a G30-900 in my Civic and have no complaints... however Supra will get a Precision.

 

Amazing numbers , I‘d love to see what would be the 100-200 km/hr or 60-130 mph , if you test it on dragy , please share the time as I‘d love to see how it performs on the street with this power on a precision 6466.I have the 6870 , best I could reach was 4.84 seconds 100-200 km/hr with V160 manual, engine stock minus the HKS 264 cams.

 

Those are some scary numbers Chris😱
