Most of the system is low pressure. The only high pressure line is the one from the pump to the rack. The lines I need to disconnect are from the cooler to the reservoir and rack.

 

I had the pleasure of seeing (V8 Roadster) Shandelle's car at Sebring last weekend. He has an LFX swapped NC. I was totally surprised at how nice the exhaust note sounded.

He also did a few hot laps in OG Racing's LS powered NB which was pretty cool to watch.

 

I wish I would have known that I want to here what it sounds like I will be at Sebring for the 12 Hour race, no more Mazda Coral :-(

 

The NC has a full Borla exhaust and it sounds very nice, the NB has custom exhaust and sounds a little more angry/exotic but is quite a bit louder

Ryan,
The build is coming along very nicely. I'm anxious for you to get it on track and see what you think

 

More fittings arrived, working on it this afternoon.

Regarding the exhaust note, I'm equal parts excited and apprehensive for how loud this car's going to be. I expect it's going to sound fantastic, but with the side exhaust the volume level will probably be... up there. Thankfully it won't matter for most of our tracks in SoCal out in the middle of nowhere.

 

Any mufflers at all or are you just running open pipes out the side?

Nevermind, went back and see the mufflers you're using.

 

I know what you mean, my side exit came out a little louder than I expected but god damn the sound is worth it

 

Perhaps the one saving grace will be that I designed v-banded cats into the system from the beginning with the plan to later make short test pipes that can be swapped in. If it's absurd with the test pipes I may end up running the cats to quiet it down.

 

That's a similar idea to what I was thinking for mine, but 300-400 for a 4" cat is hard to justify. On the other hand when driving it on the street at stoplights I end up breathing some nasty fumes so it might not be a bad investment depending on how many street miles it sees this year.

Currently I just have a burns muffler and it definitely quiets it down but I'm trying to quiet it down some more this year. I'm guessing the cats will do a better job seeing as you have two and they're a bit long than my 12" muffler

 

looks so clean. i love and hate that lol.

 

Doing some napkin math for other fun places the car may fit in.

Looking at NASA, when you move above the complicated mess of the lettered classes on up to ST/TT 1, 2, 3 things get much simpler. With a good bit of power taking the tighter-regulated TT4 out of the question it gets even simpler. Basically take a dyno and weight baseline which then applies modifiers for certain mods and you end up with an adjusted power/weight ratio and that's that. Everything in class is same adjusted ratio. Obviously this favors a wide torque curve, and this motor should be great for that.

TT2 cars have an adjusted wt/hp of 8.00:1 or more (up to 10.00:1 which is TT3)
2300 lbs with driver / 300 whp = 7.67:1
Relevant adjustments:
Comp weight over 2200, less than 2599 = -0.2
Tire size 245 or smaller (DOT approved) = +0.7 or Tire size 275 or smaller (DOT approved) = +0.3
Non-production vehicle = -0.4

A note on the non-production vehicle bit.. have to take that due to the tubular front subframe, but this comes with some benefits. First, I don't have to take the -0.2 for cutting the rocker for exhaust routing for production vehicles, so it's really only -0.2 more than if it was considered a production car. But more importantly, with it considered a non-production car there's no concern about the tubular/removable front nose being OK.

So, with adjustments, 7.77:1 with 245 tires or 7.37:1 with 275's

Ballasting up to 2375 lbs with 245 hoosiers puts me at an est. adjusted 8.01:1, right at the pointy end of TT2.

While RLTA and GTA are my primary focus... and yeah, TT2 is full of Vettes and Vipers, it could be fun to mix it up there and see how it stacks up. Always love a challenge!

 

I ran my E car at 2375 most of the year. It would be bonkers to have ~double the power + aero in my car with as good as it handles.

Has Sean been poking you about NASA as hard as I've been poking him about it?

 

don't let corvettes and vipers scare ya off. i monster the tt2 vettes in the braking zones. and that's me on rc-1's and them on Hoosiers.

 

I'm not eager to do a ton of TT with NASA, my main focus will be GTA, but more options can't hurt. Also, in RLTA and GTA the class is limited to 100tw (245 RC1) whereas in NASA TT it'll need to be Hoosiers, so cost to play increases substantially.

 

Continuing to wait on a few more parts to arrive, so I took some time to get some of the suspension bits assembled.

Pressed out all of the old polyurethane bushings and now installing for evaluation a spherical bearing kit for the factory control arms from a shop up in Canada.



Spherical bearings within the press-in sleeves:



I've run into a couple snags with some of the parts in the kit, shot some feedback to them to get those bits resolved instead of having to machine my own solutions, and hopefully we'll get things sorted out. Nevertheless, the majority of the kit is installed and ready to rock.

Also going into the arms are Bauer extended lower ball joints and V8Roadsters rebuildable front upper ball joints:



Finally, I'm replacing the rear upper arms with V8R's tubular Pro series arms. Feedback from Steve about what they've seen on other cars, the rear upper arms are the ones responsible for wheel hop and other funkiness when putting big power down as that factory arm twists with enough torque. The tubular arm solves this, and the pro series has spherical bearings to match the rest of my arms.

Oh, and in my recent powdercoating frenzy I had all the factory arms done.

 

A lot of jealousy right here.

Spherical bearings are Le Sex.

 

 

^what they said. given.

 

Just curious:

why ballast up ~75lbs instead of tuning down to 287?

I might be overlooking something but since Im building my car for double duty as well - its relevant to my interests

 

I imagine the only way that is happening is if they are getting on the brakes too early by a measure of football fields, and likely also running at TTC pace like yourself.
