Wonder if a pure 3rd gear pull would give a picture of the entire powerband? Regardless, I'm going to use this method to test out my car before and after mods.
I have a c5z with a lot of hp and have done the 3rd gear pulls for years because 1st and 2nd are traction limited. Op, you are doing a great job on that car. Inexpensively too.

Thanks chuck! As long as you can do your own labor, it's fairly affordable to go fast.
Awesome!! I will hook up my goPro and try track mode with full E85 this weekend. My goal is 4.8! Great job on the shift!
I lifted on the shift like a sissy. I haven't driven the car in like a month.... I did get some wheelspin so I think I can get the time down, this was also on 93. I have to run out of gas first, then E85!

That ported intake and TB really help out! I'm on a beta flex fuel tune at 50% ethonal so I'm excited to see what this thing can do. I like our new measurment!
What size headers did you go with? How much did you pay for those headers? I show those headers are 2K on their site so must have found a deal?
You can find the catless X-pipe and ARH headers for around 1800 or so.
I bought the Texas Speed headers (1 7/8) and AFE CAI "package" for like 1300 or 1400 so that's where the HP/$ is....
I had ARH on my C5Z and they were fine. I really don't find any difference except the TSP primaries are significantly longer. Which is better can be debated all day long and at the end of the day....they don't perform all that different.
I have been slowly but surely adding mods to the LT1, and have my own unique way to measure performance. Below are my findings
Due to not having access to a track any day throughout the year I decided to gauge my performance by measuring my acceleration time from 40 - 100 MPH using the track stop watch feature.
40 - 100 MPH
Bone stock:
I was able to perform over 20 passes when stock, and my absolute best I could get was 6 seconds flat.
Dyno: 417whp
Mods: Stock
Time. 6.0 seconds
Intake/Tune
I did another 20 passes, and my best time was 5.7 seconds.
Removed RunFlats
Started to get cold outside and snow was becoming a issue. I ditched the stock tires, and got a non runflat all-season (traction for days!)
Flex Fuel Sesnsor + Tune
Installed a Gen5 Flex sensor, and tuned the ECU to allow the Corn Syrup. This pass was done with only 50% Ethanol blend for testing purposes, I confirmed that % by reading the ECU. I have only made ONE pass, and this was the result
This car is ***** to the wall fast now. I trapped in the quarter mile 117 MPH bone stock when I was turning out 6 flat with my tests. Once I go full E85 later this week, I expect to be in the 4's with ease. I don't want to start the troll wars, but I feel with just bolt ons and Flex fuel, this car will trap well... like really well, dare I say faster than a C6 Z06?
I'm currently only $2K (not including tires, i actually needed those) deep in mods, and now have a car that is capable of 10 second passes when it's all said and done (with slicks). I will post more details on my findings when I'm full E85!
Who is excited?? THIS GUY IS!
This is a great idea. Thanks for sharing. Wish I could go back to stock and try it. Will give it a shot before the meth upgrade.
