My mods are websites tune, weistec filters, weistec plugs, ams catless downpipes.

Fuel used was 93/100pump mix that I think was old 100 octane here in(Long Island, ny)
Ambient temp: 62
Da: +268ft
track elevation: 105ft
Full interior
Gas level was inbetween half tank and a 1/4 tank.


Times ran:
93/100 pump gas mixture
11.33 @ 125.48. 60' was 1.834(brake boosted launch at 2k rpm)
11.28 @ 125.71. 60' was 1.809(race start)
11.31 @ 125.86. 60' was 1.829(race start)
11.28 @ 125.10. 60' was 1.840(race start)

That's impressive!! Nice runs and nice consistency

Interesting how everyone's experience with race start is a bit different at the track

How do you think you did... What are your thoughts on the times considering your investment in mods

Well I'm a bit disappointed. Thought if see an easy 11.0/11.1(for sure) considering some run that with tune only. But I had a bit much gas in the tank for that. And I'm convinced my 100 octane station had **** fuel.

I hear ya

You had ideal elevation and temps are ok... The weight of the gas shouldn't have given you 0.3

I have seen a guy with a rebellion piggyback tune ran 11.25 and he ran 11.5 stock both runs on pump gas

Every car is different in how it launches

Next time I plan to be on fumes and 93 only or straight 100. No mixing octanes. What's ideal tire pressures. I'm running 46 front, 51 rear. Is brake boosting a launch better than race start?

Sdg, a member, stated that brake torquing at 3000 rpms was ideal for him

Maybe drop to 41 psi all around (cold)

Your launch is single handedly going to be the key to getting to 11.0-11.1

I shall try. I couldn't catch traction in first. That killed the 60'. Will try the 41 all around.

3k brake boost jeez. Can't be well for the tranny lol

Nope, not good for tranny lol!

You have 4-matic right? Or are you in Europe and have rwd?

I'm in the states. New York, Long Island to be exact. Not far from sdg.

Good consistent runs. Trap speeds leave a lot to be desired.
Looks like the second Weistec E63 with traps in the mid 120s mph

Is that good? Mid 120's lol

Yup ... It speaks to how much power you're making

Is it my eyes playing tricks with me or are the video of your runs, you started late? If so I think you would have more impressive numbers than what you got?

Question. Which website tune did you go with ?

I got my best times using Race Start, gas tank at 1/4 or less, on 94 oct, 40psi front - 35 psi rear. Times in sig.
UPD CAI and Crank pulley on order, will go back when I get those installed.

Clock doesn't start until you move off the line so the late start has no effect on et's.

I made a mistake. Track elevation was +515ft. Not 102ft I said earlier in the first post. That's why my times were hurting a little. I'll retry at Atco within the next two months when we get a track rental.

I heard these cars like hot lapping. And to launch and get a 1.6 60' you turn traction fully off and brake boost 2.5k for the launch

Oh you didn't have traction totally off with brake boosting?

That can explain a lot

your DA was 836 ft for that day and weather, not great but also not a DA that is going to totally kill your times.(see calculator results below).. I think not turning traction control off would be more the issue with your times, but i still would of expected a little more mph on your runs given your mods

DA calcuator :
Correct your ET and MPH using the DA (Beta Testing)

Density Altitude: 836feet above sea level
1/4 mile ET: 11.284 seconds
1/4 mile trap speed:125.10 MPH

DA adjusted results:
Stock and Mildly Modified Naturally Aspirated Engines
11.195 @ 126.076 MPH

Extensively Modified Naturally Aspirated Engines
11.268 @ 125.45 MPH

Extensively Modified Supercharged and Turbocharged Engines
11.271 @ 125.252 MPH

I think so too lol

1.80 - 60 ft is decent, but should be better considering 4wd and all that power. That trans really does hold the car back off the line. Were you on winter tires?

125mph is not that great when the average should be 127-129mph. Maybe traction control killed it for you

Stock summer tires with 4K miles on them. Still new
