CTS TR 1070-X

[unmarkedA4]

And your saying to me that that thing doesn't slip like crazy when you push hard on the gas? The steel belts in those transmissions aren't even rated to hold that level of torque.

No it doesn’t. Hooks and goes

Got ya. I’ll use vcds! They have that option when you have advance measurements up and select speed

I’ll do more logging this weekend. Suppose to be really nice! I’ll do a 93 log and maybe 100

Just ordered mine. I’ll get some pics up before install and do a side by side comparison of my regular TR 1070 vs the X version. Without a dyno I’m going to use some of my previous logs to compare performance between the two. CTS claims there will be a noticeable difference between the two so we’ll. I tried to get them to comp the turbo if I sent them the regular 1070 back but no dice lol. It was worth a shot.

If you can do some before & after Dragy runs too, that would be super helpful! Interested to hear your impressions

Logs are not a definitive way to measure performance of your car. You will be able to see if one turbo flows more air than another but does that mean it performs better?

The best way to gauge performance of your car is to measure how long it takes to accelerate. Buy a Dragy or take it to the track for a better comparison.

New turbo is here and ready for install when I get some downtime! I’ll do a side by side comparison of the TR1070 and the TR1070-X when I pull it but the X version does seem pretty solid. I don’t remember how many fins the exhaust turbine had on the 1070 but the X has 12 and you can see edges have been trimmed. Looking forward to see how it performs.

[Jason11213]

Couple of measurements on the new turbo. I am waiting on the turbo blanket to arrive then I’ll do the install and post some logs. The quarter has already been taken out of the turbine side in case anyone asks lol.

[SNice]

Really looking forward to the comparison and logs! My theory is that the only difference between the two is the CHRA. Here’s a similar picture of mine (1070) followed by the 1070X. This is just a preview - the true side-by-side will solve this riddle!

missing the only important measurement when comparing different K04

- Exducer /inducer compressor wheel size
- Exducer/inducer turbine wheel size.
- turbine not clipped or clipped (if possible get clipping angle)
- does compressor wheel have extended tip? What size?

other part measurement would have super marginal impact on power when comparing K04 shell turbo.
tolerence between wheel size and housing would have more effect that those housing measurement on turbo efficiency. ( how close blade are to housing)

So without taking it apart there’s not much to gain from this?

Here’s where I’m at with this: I’m hoping this 1070-x will perform similar to the Old CTS modified BW K04 (no longer available). I’m also hoping that the only difference between the 1070 and the 1070X is in the CHRA. If so, a CHRA upgrade would be a possibility. I don’t think it would make financial sense for CTS to have two separate molds for these two models. I do think they have different spec CHRA’a though.

CTS don't need different mold.
their is plenty of compressor and turbine upgrade wheel available to fit on a "K04" CHRA on the market
then just need to mill compressor and turbine housing according to your choice of wheel.
Easy for CTS to source some company in China that can mill with 5 axe's cnc the housing according to their choice of wheel. If they want to do so.

[Jason11213]

Finally had a little down time to pull my 1070 and swap in the 1070 x. First impressions of the turbos side by side is there is no discernible difference in size from what I can tell. Below are some pics of the two turbos and measurements. I’m tracking down a small coolant leak (one of those damn banjo bolts with a crush washer) and will hopefully be able to log some data soon.

Definitely keep us updated on power and maf differences between the two turbos.

[Jason11213]

Fixed the coolant leak and thx to everyone on helping me trouble shoot a massive air leak. The coolant leak was my mistake (I guess all the problems were technically my mistake lol) because I didn’t pay attention to CTS’ instructions. They use a thick copper crush washer for the coolant line that has to go on the inside of the banjo bolt closest to the turbo. I had it reversed but once I switched them it was all good. I must have not tightened the hose clamps enough on the charge pipe to compressor or the TIP. Not sure which one it was but that fixed the boost leak. I took it out and there is definitely a noticeable power difference between the 1070-x and the 1070. My butt dyno got used to the 1070 over the past year and the x does pull harder. The surprising thing I wasn’t expecting though is a lot less turbo lag. Normally in second or third gear I would get that 2-3 second delay before the turbo kicked in and threw me back in my seat. The power is almost immediate with the 1070-X. I’ll see how the software adapts to the turbo and what changes. I’m going to jack the car up tonight one last time and recheck all the connections before I do a third gear pull. I’ll post MAF, timing, n75 etc… when I get a chance. All of my old logs on the regular 1070 are buried in the thread for the B8 K04 follow up. But with that I was peaking around 265 MAF g/s with 16-18 degrees of timing advance by 6500 rpms. I can’t imagine timing will change much but fully expect to see higher MAF readings based on how this turbo feels.

You should still do a leak test, just because you don't hear it as obviously as it was before doesn't mean it is not still leaking.

Good point. I was going to log boost actual versus requested to confirm when I log but I can try a leak test too. Any DIY write ups you recommend? Also, I have a limited selection of tools. This was my biggest undertaking in terms of car repairs so I’m learning as I go.

That's horrible.... Great, I've got the 1070 waiting for me in a box on the garage floor.

[Jason11213]

Haha it’s not that bad. I got used to it and liked the “snap your neck” boost I would get in second gear. Third gear isn’t as noticeable of a boost lag. I drive a manual and am on Unitronic’s tune so it may be completely different on your setup. I ordered a boost leak test kit from ECS so I’ll double check everything is tiiiiiight before I log. Honestly, if the difference in horsepower is 30-40 (guesstimating based on CTS’ claims) then you’d have to weigh the additional costs. Is $500 more worth it for the 1070-x? Plus it looks like CTS is sold out of the x version online.

[flowhigh]

Heck if you have the money yeah 30/40 ponies and less lag is definitely worth it. That performance over a regular k04 is a deal breaker.

You probably sold everyone here on the x and they ran out 😄

I may have to invest in a gfb diverter adapter if the lag is too far off from stage 2.

[SNice]

Ha! Yeah - after your initial report - I went and checked — “out of stock”. Lol. I just put too much money into suspension and wheels. This will have to wait for a bit…
I can’t wait to see your results once you start logging. I have a feeling that MAF number will be nice. I haven’t been able to break low 270’s (g/s) on the regular 1070.
Also looking forward to how it spools on the graph!

And it seems to be running fine on your current OTS tune, right?

I would have stuck with the 1070 if I didn’t clean out my garage and sell a bunch of old parts. Once I sold my stock cat, stock IHI turbo, stock black optics grille and now the 1070 it was a no brainer to try the x version. Below are my old graphs from months ago on the 270 and I never broke 270 g/s either. We’ll see how well the x version does when I log it. And yes the OTS tune works fine so far. I haven’t pushed the turbo really hard yet but will soon. I would imagine if you went with a custom tune on this turbo you would see better gains. Unitronic’s tune does this odd thing where it quickly blips the requested boost around 2800 rpms up to 23 psi then drops it back down to 21-22 and slowly tapers down to redline which you can see in the graph. I noticed APR’s tune keeps the boost requested level throughout the rev range. I guess Uni’s difference is the timing advance is higher to make up for lower boost requested. I’m sure a custom tune could do a lot more but I’m not willing to deal with constant logging and revisions. I gotta say CTS did a great job supplying all the needed parts and the install was fairly straightforward.

[Jason11213]

Yes - my exact question and was never able to get a definite answer. I don’t understand why it wouldn’t work - or why it needs a “special” hybrid tune. I feel like the word hybrid is being used to mean more than one thing.

I also wonder if the only difference between this and the regular 1070 is the CHRA? Could I find a similarly spec chra and pop it into my 1070 and effectively have a 1070-x?

It seems like the benefits are quicker spool, reduced lag, and more power. Could definitely be worth it!

I think you hit the nail on the head with this. I’m not willing to dissemble the 1070-X but I bet the only difference between this and the 1070 is the CHRA. If you can replace the CHRA on the 1070 you should be able to make it effectively a 1070-X. The question is which CHRA do you use for the replacement? All I can see is the turbine fins are clipped on the X version but there’s got to be more to it. I am waiting on a replacement bracket bolt to arrive from ECS (the upper turbo bracket bolt is no longer there so the turbo bracket is just hanging on by the bolt connected to the block). I don’t know how much support that bracket actually offers since the exhaust manifold is bolted to the block but it’s a cheap part to fix. Once this is on I’ll be set. I also went ahead and order a turbo muffler delete to install. I looked at the forge diverter valves but it sounds horrible IMO. I’m used to the pssssh sound a turbo makes not the flutter sound these DVs make. Also have the turbo blanket to put on.

I would be interested to see if someone can find a comparable CHRA to the 1070-X and then just make their 1070 an X version.

[19birel]

I would be very interested to see how this turbo setup traps in the 1/4 mile, or better yet what it makes on the dyno. It seems like 320whp has been the threshold on this platform for those running meth or E85 (closer to 300whp for just 93octane). Would be cool to see where this falls in that mix.

Yeah - I'ma have to check back in some of the older K04 threads - those guys did all the groundwork as far as hardware goes - the info is already there (I think). I'm pretty sure there were some CHRA options listed there...

I'll second that the 1070 is the same as far as housing goes. I was comparing mine still in the box to the photos of your X and have to say that they are the exact same thing.

I didn't notice the possibility of a muffler delete(on turbo outlet) because it isn't bolted in...if there even is one. I peered into the pipe and didn't see any porting like on the IHI K03, unless I just didn't see it. I was thinking to myself that it was a waste of material just to make a fake muffler housing out of the mold.

I really hope all the little porting in the CHRA are good quality and not all clogged up with material. If not it isn't going to last if the oil doesn't circulate properly through it.

D’oh! You are right. No turbo muffler to delete. I was trying to throw something on the order to bring my total up for free shipping and wasn’t thinking. The bolt was only $4 and I didn’t want to spend $6 to ship it. Well it’ll be going back and they’ll be getting more of my money for brake upgrades. I can already tell the stock brakes won’t cut it with this setup.

Glad I told ya.

Yeah, kinda lame how they made a fake muffler...says China all over it. It would've been cooler just to have it straight like the original BW version. If you're b8, you can remove the plastic muffler on the cold side of the intake plumbing just in front of the driver's side wheel well. I think you can do it from the fog light assembly if I'm not mistaken. This may help, but not much as a delete adapter on the turbo.

I deleted that sound box you're referring to and I noticed a difference. Nothing crazy, but the car was a little more responsive for sure.
