One step closer to the Bolt-on LT1 record
The weather was decent today and I wanted to tweek with my tune as well as tune the suspension so I hit a Test & Tune session at my local track...
I was happy when right off the trailer and todays baseline looked like this: 60' ... 1.676 330 .. 4.968 1/8 ... 7.752 MPH . 87.98 1000 10.150 1/4 ... 12.161 MPH . 112.64 A few changes got me to: 60' ... 1.655 330 .. 4.932 1/8 ... 7.704 MPH . 88.28 1000 10.100 1/4 ... 12.107 MPH . 112.76 Playing with it a little more got me to 12.0's, an by this point it was well into the afternoon and hotter: 60' ... 1.642 330 .. 4.921 1/8 ... 7.694 MPH . 88.36 1000 10.085 1/4 ... 12.088 MPH . 112.99 I followed that up with another new best of: 60' ... 1.639 330 .. 4.910 1/8 ... 7.684 MPH . 88.29 1000 10.076 1/4 ... 12.078 MPH . 113.16 Just another lightweight bolt-on LT1 car... :p |

The last time I weighed it we were at 3190 with me in the car, that was a few weeks ago, I think today it might have been +- 5# today depending on fuel level. The car itself is about 2975 depending on fuel level, and I try to only keep between .5 - 1.5 gal. in the tank, but one time today I lost track of the number of runs I had and ran out of gas in the staging lanes, with keeping it that low the gage is alway on empty...:eek:
Wow, that's light LOL. I was looking at some of your pics on another site, nice work man. Mine's a pig compared to that. I worry a little about you keeping the tank that low, it seems like the fuel pump might overheat. Then again, that's an extra 10-20lbs you don't have to lug around. (I run with about 4gal) Great times though. keep up the good work :D |
I forget guys, what is the record? Thanks, Rick.

Randy - what weight reduction have you done? |
just the simple stuff, front bumper support, carpet, seats, and little things. I'm about 235lbs, so that puts the car at around 3150, so if I could knock another 150lbs off I'd be happy. Just like it sits it should run high 6.60's this fall and I think I need to have it retuned again, it's a tad lean for what I need.

Ok I was getting the car ready for my race tomorrow, and decided to change the oil since I honestly don't remember when I last did it, well I was working off the 3000 miles thing but forgot that I don't drive the car on the street anymore... :no: So I decided to try royal purple, it is actually purple oil :think: , and when changing it the old stuff was black, and when I pulled off the oil filter I found that it was the same one in there when I installed the headers last year in May because there are still marks on it from the header install... :eek:
I also checked my fuel filter, and it was pretty dirty too, and realize it hasn't been changed in over 4 years... :eek: I guess we'll see what tomorrow holds since I actually did some maintenance on this damn car, I wonder if this would be enough for 11's, I guess only the weather will tell... |

I pulled the pan this last winter after running RP oil and will never use it again. It had an 1/8'' of black coating on the windage tray and the pan bottom after just 2 seasons of using it. Keep in mind that my car goes one season on the oil, that's 100 miles. Never had that with other oils.
