New Best 1/4 mile

Installed some new parts on Keira so it was time to see the difference. I installed a TPI air foil which I didn't expect anything from and March under drive pulleys which made the engine feel a lot more responsive with better mid range.

I didn't improve as much as expected but consider my run had an average 60' and not the best trap speed with shitty gas, a 13.602 is a definite sign of improvement.

 

This car has some serious rubber!

And I started mocking up flares on Megan

New Best Time

Supposedly the L98 c4 is plagued with false knocks so at some point GM produced a replacement Knock Module that was less sensitive. Through some cross referencing online I found a new knock module for $30 from rockauto. Install took 30 seconds and then I decided to perform a very scientific test known as "seat-of-the-pants." In all honesty I thought it made the car worse. However my car consistently managed 100mph trap speeds at the track with shitty launches. Temps were slightly cooler then my other runs but its safe to say it didn't hurt the performance of the car.

My first launch being my only good one and best to date resulted in a new best time 13.675. Woot!

 

This car is awesome!!!! The aero body looked extremely well designed, nicely tight and compact too. Center lock wheels FTW. However I don't understand why this guy just sat in the pits tightening the odd bolts here and there and not even attempting to drive the car.

These guys just spent the evening hiding but there was plenty of nice cars on the track to provide apple action.

New 1/4 Mile Time

Set a new best 1/4 mile time this past Friday and new best mph. 13.8s and on a separate run a top speed of 101mph . New mods were light weight battery (-27lbs) and Z51 front lip.

FYI car in the left lane was a Jeep SRT8... damn!

At the end of this week I'm going to order a number of parts that most people probably wouldn't consider a performance mod. Hopefully we get some good results!

This Fridays weather isn't looking to promising but mods on order are Z51 lower front lip, and light weight battery probably arriving by next friday.

1. I'm expecting to save 25 pounds on the battery by switching to an odyssey light weight battery from the current optima redtop. I'll probably leave my emergency tool bag at home to save an additional 25 pounds. total -50lbs

2. I Don't expect much difference from the front lip if any. I'll probably increase the tire pressures considering I had no issues with traction.

3. Finally I'll see if removing the license plate has any effect as well. (popular myth)

These are relatively cheap easy mods that I want to get out of the way. Slowly I'll work my way up to more expensive mods including my super ram intake that I have collecting dust in the basement.


Dreams... If my car did this everything from the drive shaft back would explode :(

Quarter Mile Baseline

I headed down to Toronto Motorsports Park this Friday and baseline'd Keira (85 vette). I'm happy with the results considering I did nothing to optimize the car for drag and didn't really do any fancy launches.

Best time and mph 13.913 @ 98.47mph
