My car is not geared for the 1/8. And, interestingly, neither was my '03 Cobra, even at LACR, when Bernie shut down to the 1/8th due to slippery conditions. Of course, it depends upon gearing and tune, but, I know that the 5.0 slug is a dog to the 1/8th, and I hate to not be able to represent.

And, FYI, I checked and there was an extremely tight relationship between 1/8 ET's and 1/4 ET's worst. They march in syncro so well, that my two worst 1/8th ET for an 11 sec run were directly associated with the two worse 11 sec passes.

7.772 @ 91.35 netted a 10.997 at Fontana, and 7.773 @ 90.32 netted a 11.995 at LACR. So, it would seem that you would need to do a solid 7.7, 1/8th lap @ 90+, at the Dale, due to good DA and prep there, to have any reasonable belief that any kind of 11 sec pass at Famoso will happen. And, if you have stock 3.55 gears, you too will be a bit too tall geared for the 1/8th, as I seem to remember that 3.55's do about 105 @ 6500, so. third is a bit tall for the 1/8th. In fact, those Terminators that have moved their rev limiters up to 7000 RPM, are geared better for the 1000' at WIllow, as they can use all of third on a pass, yet, save a shift to 4th.

Good luck. It will be interesting to read about your experiences at the Dale.

Bummer, that would be taking a lot of vacation time for just a little 1/8 mile racing.

I hear you on that. If I wasn't in such need for 60ft work and seat time, I'd probably never consider visiting an 1/8 track, especially with a Terminator.

Thanks for the 7.7 @ 90 target! :violence-bowandarrow: As always, I appreciate the specific data to use for comparison!

I'm looking forward to getting some baseline runs which will help me know how much work I have in front of me. :tools-hammerdrill:

:occasion-xmas: Although I'm in no rush for the holidays to be over, I am anxious to get started!

It would seem to me that your reasons for visiting the 'Dale are to work on your burnout, (too short less hook, too long less hook), your rpm and tire pressure at launch, and the 2-3 shift under real event pressure. This is "basic training" for you, for the guys with hundreds of passes it would be a time waste unless they are having "drag strip fever" and just need a couple of runs. I can't imagine anyone "optomizing" his car for the 1/8 unless it was stated that all 1/4 tracks were being closed. Your car will be, in theory, one of the fast cars at the track except for the "real race cars", and you will run faster than some of them too.

Go practice, have a good time, meet some other folks working on their game. You might need only two visits, 3-4 runs each visit to say "I'm done, nothing left to learn here". Or you might find that it is not all natural for you and your car. And you might find that there are some good folks there, some helpful folks there and you might want to check in from time to time to "sharpen the saw". We can calculate your anticipated 1/4 mile times from your 1/8 times. If you are not getting a good 60' time at the 'Dale, no way will you get a fast time at Famoso.

But most of all, have some fun with that toy. :whistle:

Outstanding advice from all, leaving me with nothing to add. I guess that is a good thing.

Well, I'm really grateful for the advice to get some practice runs in at Irwindale.

I could not get the R888s to hook at all.

I had massive wheel hop in first and second all night.

I even lowered the pressure each pass starting from 20 down to 15 psi with no success.

60fts actually got progressively worse through out the night ranging from 2.0-2.2 on the first three passes. The last run of the night I did a "Willow" style "no launch/leave from idle" and it clocked my 60ft at 2.8! LMAO. Even this soft of a launch the car still wheel hopped as soon as I got into any decent throttle. The MPH on that run was 86.

I'll be picking up some rims and tires to go back and get some baseline runs on the different set up.

Good for you. Just doing it, and planning to do it again.
