First time at the dragway, as spectator and participant. Had a great time. Still trying to figure it all out...ride height, suspension settings, RS, Sport+, etc.

Nice evening here in central Florida. These were my two best runs, and also my last two runs. Will definitely go back to practice a bit, and I'm sure I'll look for some incremental power gains as well. Good times.

These were both brake torque runs. I did utilize race start a few times as well with similar results, but these were my best.

2nd best...11.573 @122.91 mph
best..........11.552 @122.20 mph


DA of 2374
93 octane

Are you stock? Those are pretty darn good results congrats

Ralcbah

Not stock, Peter. Tuned w/ catless downpipes. First time out. The numbers are what they are, but I'll be back. Highly recommend getting out to the strip....pretty cool.

Fairbird

For tuned and catless slow , hello rentech.

Ralcbah

Yeah. I realize not even close to the fastest tune/piped times. Just sharing with the group.

Fairbird

I'm looking at your 1/8 mile , 7.5 / 96 , my stage 1 , not even catless , same DA

Ralcbah

You and your car are definitely a good bit faster.

Fairbird

I'm stage 3 long time ago , just saying , your result can be better , your 60 ft not bad . should be faster .

Ralcbah

For sure man...I follow your build journey. I'll go back in a few weeks and play around some more. Faster would be better, of course, but it's all in good fun.

Fairbird

keep us posted , good luck

Heyy, that's great for your first time out! I went to the track yesterday and had almost the same results. The biggest problem I found was the car heating up in the stagging lane.

11.66 @ 124
1.88 60

i cant remember if was you or other member, but didnt you dyno around 620whp after the addition of your dps to your tune?

i am surprised at low trap speed for the amount of hp/ mods you have... 122mph is close to stock trap... do you log your runs? maybe your car was pulling timing on those runs

Ralcbah

Very cool. Nice way to spend a Friday afternoon.

Ralcbah

Yeah man. Car dyno'd at 620whp. No, didn't do any logging. Sounds like that may be a wise step for the next experience.

gaspam

yeah i would do some logs or give renntech a call if i were you as something is a miss... you should be around 127mph or so given your power

Ralcbah

Hit the track this weekend. Another warm Florida evening, but good attendance.

- lowered tire pressure to 45psi (was > 50 last event, as my tires had just been swapped)
- mix of 93 octane and 100 octane (1/8 tank 93 & 3/8 tank 100)

Best: 11.53 @ 124.25 mph ....used race start

Tried to brake torque once, must've been too high in rpms, bogged it, ran a 12.x. Going to practice launching with no RS.

I bought a ODBii scanner, but didn't run it yet. Will do when I have more time to prep next visit to the track.

Ralcbah
what were your 60ft times? Did it take a few runs for the car to get used to the race fuel mix?

Ralcbah

I want to say in the 1.8x range. Don't have my slips with me, but will post them on Wednesday.

I put about 30 miles on the car with the mix prior to racing. First pass trapped at 124mph....about 2 mph higher than with 93 octane only.

sdg1871

Exactly. That is where I am on a Renntech full tune and Renntech sport mufflers -- 11.1 at 127.56

sdg1871

My best times are without the race start. When you brake torque it release the brake by sidestepping it at or before 2500 rpm's

Ralcbah

Those are great numbers. If I recall, you brake torque, as opposed to using race start. If I can figure out how to launch without RS, I would expect to shave a tenth or so.

Ralcbah

Folks, what variables should I log?

sdg1871

Thanks. Yes we had at least 50 to 60 launches that day and we tested it both in race start and brake torquing and found that the best results were from brake torquing where you release the brake at about 2500 RPMs.

To do it properly you step on the brake first and floor the brake. Then your floor the gas and simply let the revs come up to about 2500 and release the brake. it's that simple

Ralcbah

Cool deal. Thanks much. I'll forget about the tree and focus on watching RPMs to get consistent with this method.

sdg1871

Exactly. Forget the tree. You're not racing against someone else. Just perfect your launch. These cars don't launch as well or easily as Porsche 991 Turbos which are fool proof to launch. You have to use a little more skill with the E63z
