I'm keeping my fingers crossed for someone with these turbos posting a 93 octane run without meth!

Does anyone know if these spool faster than Vargas Stage 2+?

DCT cars can't brake boost and I was wondering what option would spool about the same as stock.

Jb4 has anti lag now in beta. If you really need something like that.

From what was said in the videos seems like they spool pretty close to stock turbos.

I wish Hexon would make a different bigger set of turbos also. These dont seem that bad at all but for people wanting more than 550-600 hp it seems like a waste of money. Those numbers can be had on the stock turbos from what I have seen (although not very safe of course). Interested in seeing more from them though. I wonder why they are only rated to about 21 psi

Edit: Or am I reading that right? Is EACH turbo rated to up to 21 psi? Or together? They make it sound singular.

FYI - Hexon has the RR650's in development as we speak. Rumor is they'll have potential to be in the 700whp range. I've also spoken with Wayne at Hexon and he said that the current RR550's can push up to 30psi.

Larger turbos are in development. The RR550s are in line with most stage 2 offerings, so they will produce much more power than stock. The RR550s will hold over 30 psi to 7000 rpm, so I think they will make a comfortable safe 25 psi all day long.

Nice! That will be interesting to see, especially their pricing since the RR550's seem to be about $1000 less than other offerings out there.

That is good to know! Kinda of hard to beat for the price if that is the case, especially for someone that doesn't need a ton of power but wants a little more oomph out of the car. Or even someone needing to replace stock turbos with the potential to up the power down the road.

Either one of you know a time frame for the RR650's? I'm looking to do something with my stock turbos over the winter.

The RR650's went through some major revisions after testing the RR550's. We should be looking at an Alpha set in 4 to 6 weeks.

I think people will be very pleased when the information is released.

That completely false. U can't make 550 plus hp on stock turbos.

It's all about waste gate duty cycle.
After you go above 500 it's starts getting expensive
More fueling
Clutch upgrades etc.

I thought there were people with meth and inlets running around 550 wheel on stock turbos ?

There is a big difference between making 500hp on stock turbos and 500hp on upgraded turbos. With upgraded turbos:

- You make the same power on less boost
- Cooler everything (charge air, cylinders, EGT). Allows more timing and leaner, further improving point one and better fuel economy.
- Less likely to need as much ethanol or meth to make said power level.

I plan to upgrade to Hexon RR550s and make 420whp on Australian 98 RON (Equiv to around 92 "(R+M)/2" grade US fuel) with no meth on as low boost as I can get away with, hopefully holding boost flat all the way to redline. Could I make that power with stock turbos? Yes, with lots of boost and very little timing, sending EGT through the roof and tapering off hard after 5000. Do I want to do that? NO.

Not sure how much more abuse they would handle considering I pushed them to 30 psi. Unfortunately I took my meth off and my AMS FMIC can't handle the heat. I was hitting 200 deg IAT at Shift Sector. Time for an AD Engineering FMIC...

Any plan to up the boost when AD FMIC installed? or if meth is reinstalled? Or do you think anything past 30psi is its "breaking point"

I'm excited to see what they will do @ 22psi with inlets and E60. 30psi is crazy high and thanks for pushing them there Wedge!
