Default Gt2871r pump gas, skinny tires dragstrip fun

Best run of the day

Worst run missed a gear into 3rd

Fastest run of the day

Turns out a Miata doesn't make the best drag racing car. Car is on 205 45 15s on 15x8 storms. weather was cold around 10*C

Had launch control on for all of the runs except the one I missed a gear. Times ranged 2 tenths over the 6 good passes I made

Car will get some slicks at some stage otherwise needs more power or some e85... or which ever comes first.

I'm happy though the car is making around 270ish whp and is still going

You just need to practice, and wear the right shoes for the job.

Nice runs man. People don't appreciate a low 13's pass until they've taken a car to the track.

If there's any extra weight you can pull out of the car I feel like that helps a lot. Spare, jack, tools, and passenger seat will take 5 minutes to dump ~100lbs, and in a car that light it's a significant difference.

Thanks I am at the point where I don't think i'm going to improve much without slicks did you use launch control for your runs? Or just sheer driving ability? Either way seriously impressed with your car

Thanks! I have enjoyed reading on your progress and I understand the frustration of not being able to lay down that 12 second pass, The car scares the crap out of me on the street but on the strip you always seem to want moar power. I also agree with you that we could have some more activity in this section, keep it up I'm always excited opening up your thread

Hi

Basically ran it how it would be on the street, lowered the pressures down to around 19psi but found 22-23 psi was best for these tyres and the cold track. It must feel pretty sketchy dropping the sway bar I hadn't thought of that. Suspension is set for the street as well but far too low really.

Hope it goes well for you interested in the results

No launch control, just the right combination and practice.

The current trend in drag racing is to keep the sway bars and make other suspension adjustments.

I tried racing without the front sway on the Miata, and I don't recommend it. I think the only advantage of removing it is weight reduction, but the car almost undrivable. In a high powered car, it is way too dangerous.

there has to be a way to 60ft better out of one that was one of the reasons i went auto

15x9's with 275 hoosiers
ive also been looking into helper springs for my coilovers get that inital squat

in oz we have a large sedan people drag all the time they go get the oldest highest stock spring to get as much mechanical traction as possible

We should discuss this in your thread.
