That is fair, I never realized how ugly my original front end was until the facelift. I think a Mavman spoiler will balance the front and rear. Maybe even a diffuser.

I posted these in the FB page since I get so many questions about my intake. Colt, understandably, has left a bad taste in a few folks mouths... But my IATs are phenomenal. With the new HX, I got IATs (read from the lid / IAT2) within 1* of ambient with highway cruising, and 3-5* consistently with spirited highway driving (shoots up and right down WOT), and 5-7* in moderate traffic in the city hitting every light (Bell rd). It is important to note that due to the law of thermodynamics, it is not possible to be below ambient air temps without something like an interchiller, which is overkill for my setup of just 7lbs where I will stay. It gets 110+ here, and on days like that it'll sit in the garage lol

Mid day here. First time driving in two weeks so I drove aggressively on the backroads and pulled into an empty lot and idled for about 10min taking photos. Short highway drive and I snapped this photo.



This was later that evening. Peaceful cruise. Temps switched between 1-3* of ambient at 70mph.

I have, I do want some 15x10 welds in the rear. Traction is an issue. I bought some Racestars but them shits said made in China so I sold them. Welds are made here in the US and look much better anyway, they'll probably be my next mod.

Geez that exhaust is quiet! Can barely even here it running! I like it, makes the car more unassuming despite the sinister freaking front end look, great job on that btw. I'm looking at billet specialties streetlites and welds for my junk.

3" Magnaflow. Pure garbage, so many people like it but I miss my 2.5" Borla (vids of it on my channel), but wanted a 3" system for the blower. I'm cutting the mufflers out and replacing them with Borlas again.

Only credit I give to Magnaflow is it is loud WOT, and I get a lot of compliments from people who spot me on the road.

I am catless LTs btw. Infuriating how quiet it is.

Front bumper quick release latch mount idea is cool. Ease of access to service things and it eliminates the problematic factory piece, win win.

I agree. They were only 26 bucks each, support up to 150lbs, and I figured since I'm not removing the bumper frequently, the push-button mechanism will be free from failure for a long time. Removing 4 screws (2 on top, 2 on the sides) and pushing 2 buttons gets my bumper off! The SAP lower and splitter make the bumper much stiffer/sturdier, so it goes right on and off without issue - I hope that makes sense.

LOL, they have a mind of their own. When I upload them they are the proper orientation, when I post, they have a 50/50 shot.

Some minor upgrades

Took her apart for a few minor mods:



DMS billet manifold. Upgraded this to tidy the engine bay, but peeking inside the OEM manifold, I noticed it is has jagged portions on the inside that could negatively affect flow.



12AN ORB fittings



12AN SS braided hose w/nylon cover

I pulled the trigger on a Nick Williams 92mm throttle body. My previous 92mm Warr Performance TB made a LOUD screeching/whistling sound for the first 20-30 seconds of a cold start. RPMS would dart up to around 1100 and it would "cruise control" coming to a stop. It was evident the moment I looked at the Nick Williams that it featured a bigger IAC opening, as well as a small pinhole in the TB blade. The moment I fired the engine up, it had ZERO screech/whistle, and the IAC counts quickly dropped to ~49 counts as the car warmed up. Coming to a stop there were no more cruising, and the idle issues (random surges) were solved - even the VCM scanner showed a more stable idle. I was shocked it made such a drastic difference, but I see why people avoid the "china" TBs. And yes, I adjusted the Warr Performance TB almost weekly and I could never get it right, while the NW throttle body took ZERO ADJUSTMENTS.

Nick Williams on the left, Warr Performance on the right:

As everyone knows I absolutely hated my 3" Magnaflow cat-back setup, so I finally deleted the mufflers. I replaced them with 3" Carven r-series mufflers. I will upload a vid with some exhaust clips later today - I have that distinct idle from a LS9 cam again now, it isn't drowned out and quiet like the Magnaflow. Exhaust RUMBLES, and the butt dyno feels something extra. Very pleased, it is just as loud as the Borla ATAKs, but with a deeper rumble.

How is that fuel pump working out for you? I have the same one and it idles at 55 psi, but drops down to 20 at wot. I have 80lb fuel injector clinic injectors on the stock lines.

61psi idle, 50 wot, returnless stock lines, DW300, FIC injectors that flow 72lbs IIRC (MAP referenced, 60lbs @ 40psi so whatever that is at GM pressure). AFRs are ~11.5 WOT on 91 pump gas, 66% IDC.

I am going to a ATI 10% overdrive and stock upper, with a choppier stage 1 cam, or keeping the LS9 cam and going with a 18% lower and stock upper. I'm debating on going flex fuel sensor and e54. Either way, I'll be staying returnees but opting for Proxes fuel system with DW400.
