Yah I know the emission isn’t equal but I feel diesel is way more stringent on their emissions as a whole. Vs gas is. I don’t see any gasoline engines being reduced speed

Oh, wholly agree there.

My Cobalt has a perpetual rear O2 sensor code (I have a high-flow cat, but it doesn't "see" that it's there) and I can do whatever I please.

But God forbid the Cruze have a sensor go bad. Car is operating fine, sensor is just reading incorrectly...better limit my speed to do...what?

I know... im slacking I am going to the dyno soon gotta see what I can do with my new project and I will see what the new turbo does... it definitely has more top end even without tuning.. Oh and I have to put a new cv/axle in as it decided it didn't like summit point last saturday.... easy fix... cheap part.....nobody had one till monday.... sigh..
I haven't really looked into it much but the only difference is in the intake side... can't these be mixed and matched? and then change the cartridge?

What you can do is install a billet wheel on the cold side. Hot side won't work with billet wheel for some or other reason. You can change the core to a higher spec one as long as you can still bolt your wheel housings to it. One of two ways to go, install n better core or even ballbearing core, you'll be seeing boost as soon as you put your foot down from the line and you'll never break it, upgrading the turbo core with one that has a thicker shaft is normally wat we do in our lovely southern part of africa. Then you can also install bigger wheels on hot and cold side, turbo will need less rpms to produce the same amount of boost, that equals a turbo that can handle more boost or the same amount just more reliably. Quite simple really

The cruze looks like its' pretty flat going thru the corner. Not leaning like the car behind her....

 

[MP81]

Looking **** hot at an angle like that. No body roll FTW.

 

[shimmy816]

coil overs full tight rear.. 2/3 tight front.. and the car tracks almost where you want it. very little understeer

Hyperfest coming up down a VIR oct 2-3. The grids are full but they have all kinds of stuff to do. Ride-alongs in regular cars and drift cars and off road too.. I think there are even helicopter rides and power wheel racing.. Tons of fun... If anybody makes it look me up car 803... cruze or bmw.. not sure which one yet.. sorting out some stuff on both.

Hyper-fest was awesome... tons of fun the next one is in may so if you can get to VIR you need to come out.

Moved to HPDE 2 ... so I guess I don't have anymore excuses for driving like a total newbie...lol

Time for VIR is now down to 2:39.. top speed is 119.. both those are because I am finding better lines.... next is getting the nerves up to go faster in some places I am letting up on the throttle that I know I can go way faster in.

 

[pandrad61]

shimmy816 at any point did you install a front and rear strut bar? I’m thinking about it to combo with the coil overs and rear sway bar.

 

[shimmy816]

I actually met another Cruze driver at VIR in oct. He had a custom front brace... lets just say he had alot of time on his hands.
I don't have any bracing at all. No sway bar either. I'm sure if I installed all of them it would cut times, but for now I found with the coil overs and tire pressure changes the car is almost neutral when it comes to under/over steer. Oddly enough I learned some tips on adjustments from a team that was racing a Honda Oddesy. Not my picture but this is the same guys from the track..funny but they are in same class as miatas.

if you do ever get the rear sway bar or any strut bars let us know. I know they supposedly make a big effect when pushing hard in corners. Not so much on daily use, strut bars do look cool too lol

I'd expect the rear swaybar to make a big impact on daily driving if you have any number of roundabouts - it was certainly night and day on my Cobalt for that, but especially for AutoX...it just makes the most impact (at least with as big of a bar as I have) if you have a lot of grip up front.

The rear lower chassis bar (UR) did make a small but noticeable improvement, especially considering the price.

 

[shimmy816]

I have the front sway bar but never put it in as apparently you have to drop the sub frame.. I may do it someday. my garage is tied up with my other track car. we think it jumped timing wouldn't even start on liquid glow plug. I am in process of pulling it and will probably rebuild whole engine depending on what we find.

Yah I’m sure the rear sway would be a huge difference. But I’d love to hear how coil overs no sway would feel vs sway-coils-and strut bars. I have the coils and sway bar rear, Would the strut bars be worth the $$

The Bilstein B12 Pro kit and Whiteline rear sway bar made my car oversteer with the stock 215/55R17 V-rated tires and wheels. Now with 225/50R18 Z-rated no oversteer. I’m running -1.5 deg camber on all 4 corners for fender/tire clearance as well.

When are we gonna see a dyno sheet with the X-MAN hybrid turbo?

I got the B14 kit and rear sway ready to go. I got BFG sport comp 2 AS. Hopefully the car will be neutral/little oversteer. I am tired of plow and got to get that rear end to rotate a bit.

It won’t react like you expect. It was abrupt oversteer not gradual. In my case the stability control would take over when the rear would start moving. It was scary.

I have Michelin Pilot Sport A/S 3+ on it now and it’s planted. I’ve never seen the SC come on since the wheel and tire upgrade.

Whiteline also makes poly bushings for the front control arms. I recommend you buy the ones that come with new arms as it is a PITA to remove the OE bushings. Replacing the plastic front sway bar links with new steel units from MOOG, Proforge or Mevotech is also something worth doing while your down there. Mevotech also makes camber bolts for the front struts.

I never tried driving with the stability control turned off. I think that would be a bad idea and probably wouldn’t try it if I were you.

I drive 100% of the time with SC and TC off. The car chassis even stock handles really well with good tires. Unfortunately the throttle is so **** slow to respond that it’s a challenge unless you anticipate it’s lag. Hoping the trifecta tune helps negate some artificial computer throttle lag.

Wow that’s crazy. Good luck with that. I had VW TDIs before the Cruze and I thought they were more nimble and tight, especially the MKV Jetta with multilink rear end. This 2014 Cruze stock reminded my of driving a turbo diesel Buick sedan.

I read the throttle response with the Trifecta tune isn’t linear. I got the OZ tune, it’s mostly midrange power 2000-3500 rpm. The torque feels the same at 70% vs 100% throttle but at full throttle it revs higher and shifts at 4500.

You shouldn’t brake or accelerate in a hard turn, it reduces your dynamic grip.
