What oil temps are y’all sering on the track under hard load? I spent the weekend at COTA in Austin and was touching 260 degrees. thought our oil cooler would do better than that…

I have a DH and installed Kooks LTH. Under an accelerated right hand turn with about 1/4 steering input the knuckle of the steering shaft rubs up against the headers and vibrates my steering wheel. I installed BMR motor mounts to try and get the motor to stop moving as much under load. No luck...

Hi all, I installed JLT on my DH. Easy install. Looks great! Filters are HUGE. However, it continually throws a Mass Air Flow (MAF) error and check engine light no matter, even after resetting ECU with a plug in ODB and disconnecting the battery. Are any other DH owners with a JLT...

I installed Kooks LTH on my DH about 6 weeks ago. All has been great until this week. While turning RIGHT under load I get a vibration in my steering column that the dealership is saying is the headers hitting the shaft. 1. Is anyone else having this problem? 2. Any suggestions on how to fix...

I’ve been waiting on JLT to start shipping their Cold Air Intake but geeezzzz they keep pushing the ship date back on their web page. I’m seriously close to giving up and going with the Steeda or something else. anyone else as frustrated with JLT? Anyone one waiting for it too? I’ve never...

Purchased both of these thinking I would have 3” all the way back. No!!! Shop just called and said from the Kooks LT with the high flow green cats that they do not connect seamlessly at the mid pipe. Said there is the factory pinch down to 2” I gotta deal with. Only solution is custom fab from...

Hey everyone! I have my DH in the shop to get Kooks LT headers and Corsa Extreme catback exhaust. Had them do a dyno before so I can measure the gains. Completely stock motor. 2500mi. Handling package with a manual transmission. Dynojet this morning is Austin at 79 degrees and 89% humidity...

Hi everyone! Has anyone installed this Steeda brace with Kooks long tube headers? Curious if they fit without extensive mods. Thanks! CT

I own the DHHP and live in central TX. It’s consistently been mid 90’s this month and will soon be in the 100s until about end of August. I’m about to do an oil change and considering changing viscosity from the 5W-30 recommended to an AmsOil 10W-40 maybe even 15W-50. I’ll definitely do another...

Who can share photos of their Dark Horse hood with PPF installed? I am considering an XPEL PPF but the decals on the DH hood poise a problem. Do you do one solid piece of XPEL gloss for a more seamless look and risk the matte finish of the decals look glossy? Or have the shop try and piecemeal...

I know this is an age old debate but a lot of info I am finding seems dated so I thought I’d bring it up here. does deleting your PCV set up by removing the valve and replacing with a breather really cause long term damage to your motor? I hate the idea of reserculating oil back in my motor...

Anyone hearing anything on if any of the tuners are close to breaking into the ECU? In November, Hennessy told me HP Tuners was hopeful about before Christmas. That obviously didn’t happen! I personally want to put a ProCharger on mine but no luck until this is solved…

Hello everyone - my DH with HP is set to build on 10/16. I am currious for those who have taken delivery of their DH already, did you pay MSRP or did you pay more “market uplift”? My dealer did not give me an MSRP guarantee but they also didn’t tell me exactly how much the market uplift was...

Hello all. First time poster with a DH on order. Starting to watch some of these first drive reviews of the 5.0 GTs, I am a little concerned with the feedback on the steering. Sounds like it’s quicker but too light. Makes it really hard to “feel” the tires/road. I intend on using this car at the...
