Yea the AC delco is the stuff most recommended for the rear diff because it has the additive. The old stuff didnt used to, you had to add it in manually, but now it does.

Progress looks great! Nice job! Excited for some warmer weather, getting the itch to get the car out too. haha

Yup, I could have went with that stuff as well, but I've had good luck with Mobil 1 fluids. I just couldn't decide which aftermarket was the best to use for the T56 I have in my car so I went with OEM.

Re: Back into the big leagues: Project FRC
 

Either should be good!

What NGK plugs did you go with? The colder copper plugs (non iridiums) can cause issues with the charging system in C5s and C6s. Hopefully you dont have to deal with that, but if after a couple hundred miles you start seeing charging issues, that could be the cause.

Wideband review:

So being a tuner and a DIY car owner on a budget, I constantly find myself at a crossroads when it comes to tuning things. Knowledge is power and for me I end up chasing details that truly don't matter. This is especially true when I am logging micro changes to get 02 feedbacks to within 3% and other parameters tighter than the factory runs things.

What does matter is accurate sensors. I dug around and looked at other options and came across a product from 14Point7.

https://www.14point7.com/products/sp...a-controller-2

I have been running two of these Spartan sensors and they are very responsive and accurate. The housings themselves are weatherproof so I mounted them in the engine bay of the corvette.

I don't have many pictures of the install unfortunately, but here are the widebands in the x-pipe
https://scontent-ort2-1.xx.fbcdn.net...29&oe=594C5E14

I've been tuning with them using Lambda as my logging PID and I can say they are very responsive, very accurate, and I will be recommending them for customers in the future that need a wideband. Cost effective, reliable, fast to warm up, accurate, responsive, rugged; you need nothing else but a gauge.

You also can't beat the price of $125 each using a new Bosch LSU 4.9 sensor. Granted this isn't lab grade stuff, but for a permanent install they are the way to go. Readily available sensors and easy to find. Much better than the older 4.2 LSU sensors and closer to the older NTK sensors I am used to using.

You can order them even on Amazon and get free shipping.

With how cheap these are, there is absolutely no reason to not have a wideband in your car. What is really nice about these is they will also emulate a narrowband sensor output, I haven't tried that as I added them and kept all my stock 02 sensors hooked up; yes that means I have 6 on the car. Standard 0-5V output means any gauge can be used, or you can feed them directly into the ECU or logger; such I am using with HP Tuners PRO.


I would say 2 thumbs up for sure.

Re: Back into the big leagues: Project FRC
 

I've always heard good things about 14point7, just never had any hands on experience.

They are back from the homemadeturbo days i believe.

Re: Back into the big leagues: Project FRC
 

14 point7 is what I used to run on my car. Some people would ask why I got that instead of the more well known brands. It's because I did the research, they are so knowledgable. Glad to hear you are having good luck with them too. Very good choice! Only reason I don't run them now is Infinity has a built in WB Controller so you no need for an aftermarket Controller anymore, just plug the off the shelf bosch sensor right into the ecu.

Car is finally coming together, did a little photo shoot last night. Got the Z06 Speedlines and the RE-71R's on there this weekend.

Only a few more parts to install prior to the season start which includes:

Doug Rippie Motorsports Steering Rack Bushings
Rear tow hook
Then brakes all around including:
Doug Rippie Motorsports Stainless Steel front brake caliper pistons
Russell DOT stainless brake line kit
Centric Brake Rotors
Stoptech Street Performance Pads (Sport)

Then it's STU autocross time! :spin:

Pictures were noisy due to being shot will cellphone in twilight hours, I'll see if my real camera got anything better and swap these out.

Re: Back into the big leagues: Project FRC
 

Looks amazing.

Re: Back into the big leagues: Project FRC
 

I went from those pads to the Girodisc S/S pads on my Evo X and the difference was night & day in both initial bite and stopping power. Dust and noise was about the same between the two.

http://www.girodisc.com/Pads_c_200.html

I'm currently running the Powerstop Z26 pads on my C7 are they are practically dust-free and silent, but they did give up some initial bite vs. the OEM pads. If I were to do any autocross or track use with the car I would definitely either go back to OEM or throw in a set of those Girodisc S/S pads when/if they ever release them for the Z51.

Truth be told, I'm now a bit tempted to try out Autozone's new Duralast GT brake pads since they supposedly have some pretty legit R&D testing with Team Penske to back them up. They're priced about the same as the Girodiscs I mentioned.

Re: Back into the big leagues: Project FRC
 

Awesome! I'll have to try those next, thanks for the recommendation.

Re: Back into the big leagues: Project FRC
 

Great track mod, very nice!

Re: Back into the big leagues: Project FRC
 

Car looks great! Really dig the white!

Re: Back into the big leagues: Project FRC
 

Looking good!

Re: Back into the big leagues: Project FRC
 

Rebuilt the driver's seat this week, installed a DRM steering rack bushing and got an alignment. Novice school practice tomorrow, first MOWOG event next Saturday!

Re: Back into the big leagues: Project FRC
 

Went autocrossing at the novice school on Sunday with the below settings:

Car setup and ready to rock Saturday night:

After the sessions were completed, collected 2 cones all day:

And also one final image of it lined up.

Overall impressions: :sasmokin:


Car is wicked fast. I haven't fallen off as a racer/driver as much as I thought I would have. I heard nothing but compliments all day and I think I nearly set FTD, had one instructor beat me out in a Golf R that I know of. I was told I was faster than the rest of the novice group and the majority of the instructors; so I am REALLY excited to see what this car is capable of throughout the season with Ryan and I campaigning it in Street Touring Ultra.

There were a lot of great cars and drivers out there and everyone showed great progress. It was awesome to corner work and see it "click" for people. For me the course had a few elements that were very challenging. If I could have gotten a clean run I think a 37.9xx was possible, my best run I recall was 38.3xx. I know I ran a 38.4, 38.5, 38.6, 38.6, 38.7, 38.8, 38.8 and a few higher ones. I also had 2 mistimed runs that would have been mid to low 38's by "feel" as well; overall consistent and fast. I can't stress the importance of seat time and how valuable these sort of events are. Hopefully the car and driver(s) will be towards the pointy end of the stick.

This week, weather permitting, I'd like to install the upgraded brakes to get a bit more initial bite. I may actually throw some toe out on the front at MOWOG, depending upon how tight the course really is. Overall the car is fairly neutral and an absolute hoot to drive. The input you get and the confidence the RE-71R's inspire is mind boggling.
