Critique me!!!

Allright, I know I'm not the best driver, but I like to think I am better than the average driver. I was wondering if I could get some input on my times.

1/8 mile: 8.58 @ 89.24 mph

I am still learning how to launch with the mickey tompson's. I ran the above time spinning the tires off the line with about a 3k dump. I can't post a 60 ft time because the track here doesn't print them out, and it is renound for being a crappy track.

I also have an exhaust leak on my driver's side header, and an intake leak that I can't seem to find. My rear end is still not aligned, and I need to double check my pinion angle again, because I am still getting a little wheel hop.

Edit: This was not on the bottle

More data is required to have anything useful to say... Without a 60 foot time and DA, and without some sort of real benchmark constructive comments are almost impossible to provide except that your mph seems pretty good in comparrison to your ET. I generally run 7.5-7.7 at that mph, but without incremental times I have no idea what is going on with your runs.

TNTHUB is correct, without the 60ft benchmark to analyze on each pass you’re just running blind during test-n-tune. Drag racing is nonlinear progression. Basically you’re making ET more quickly in the first portion of the pass (i.e. 60 ft, 330 ft) and less quickly towards the end. For example; in ¼ mile drag racing you make 64% of your ET in the first 1/8 mile and NHRA uses that factor (64%) to prorate their 1/8 mile class indexes from ¼ mile ETs.

When I have a slow ET (under my normal run), the first thing I look at is my 60 ft time. And, typically I’ll have a corresponding slow 60 ft time (that is where I lose ET, w/ a poor launch). With the nonlinear progression, normally 1 tenth (0.10) at 60 ft will equal 1.5 to 2 tenths with some cars in the ¼.

Hopefully you can find a track that can provide all the incremental ET information (60, 330, Etc.) then you’ll be able to properly analyze each run.

That 8.755 is a really good ET for the few mods you have! To convert an 1/8 mile ET to an equivalent ¼ ET (calculated only), you multiply the 1/8 ET by a factor of 1.5625. Therefore you should be close to a 13.68 in the ¼ mile.

Again, I’m impressed with your ET. What is your race weight?

Based on my previous LT1 bolt-on experience and watching several of my friends with their LTs, to run 13.60s typically you'll need headers and possibly 3.73s. So, you're really running well. Where is the track you've been running at, including evevation?

When I started out I had headers, cold air, drag radials and a short throw shifter. 13.5s and 13.6s at 100-101 all day long as long as I could hook up.

For consistent launches at the track during bracket racing, you’ll need some ET Streets, or some drag radials (DRs). I’ve never run the DRs, but a large number of people use them and they perform well at the track.

I’ve spent a lot of time in your hometown a few years back when the AT&T-Lucent plant was there at MV. I can’t remember how many times I’ve been there. But from 1996 to 2002, I would have three, or four trips each year to Haverhill. Typically, one to two weeks each trip. We always stayed in Haverhill and found some really great local restaurants and a few bars.

If that is the case I will be giving you roughly a 1 1/2 second head start in Street. You better start working on your reaction times.

Yea Haverhill is a great city....they are starting to actually clean it up and utilize the merrimac river (if u didnt know that river, it is that big one that runs thru the whole city lol) they are setting up parks and resturants and condos along it downtown and cleaning it up within the next 10 years.... i've lived here all my life and it really is a nice place right near the highway, close to the beach, close to the moutains, 40 min from boston....its a great location... also Haverhill is the 172nd largest city (land area wise) in the nation. we also have a lot of history....

A 12 second car is slow enough to run Street and fast enough to run Mod. Consistency wins bracket races although in my opinion, there are some advantages in being close to the cutoff. I will probably have a second, slower vehicle, to run Street this season. I like the game.

There is something about driving to the track, changing tires, and racing that simply makes me feel good but the Camaro has reached a point where that is really difficult to do...

I slowed it down as much as I could but I think I will be speeding it back up again before the season starts which will keep me out of street.

I used to race every week to chase points at two tracks. The last two years I have only made a couple of events. This season I plan on travelling a bit further and I am trying to finalize my schedule.

I did notice they has the 2004 points still online... Going into the last weekend my car the champion that year and I were within one round of each other.

Unfortunately my car crapped out so I had a rental car. He won both days. I went out in round one the first day and I think the third round the second day.
