I am very disappointed, I have installed all parts of performance, but it's 106 miles to the quarter mile, just 13.1, please tell me what can decrease r the trap speed, I want to achieve 109 or 110 miles, please tell me to do

thanks

Drag radials and lighter weight wheels.

Post all your mods, data from logging and your last slip. It can be any number of things, including you and the way you launch the car.

gwin

Have you stripped the car? FRP/Carbon bonnet/boot, removed all carpets, light weight wheels, replaced seats with racing one piece seats, removed back seat and all audio equipment and the entire dash?

super-amg

my mods are

pump jonsonm
SC 62MM pulley eurocharged
tune eurocharge
manifolds , and DCAI needwings
shorty headers eurocharged
magnetor cables and NGK bkr6eix-11
alcohol-water injection
resonador and cat , delete
a big HEAT EXCHAN
NeedsWings Intercooler Fluid Isolation Kit

with all that mod , only 105 mille sometimes 106 , somebody tell me what i need to check

Lenin

The mod list looks good. How about the time slip? If you want any help, it's important to understand where you are losing the time (at launch, mid or top end).

super-amg

i think my problem it a top end , i need more mille , please tell me what i need to check , the spark plug?? or wat

Lenin

Your problem is the first 1/8 of a mile. To finish at 12.9 sec. your 330ft should be 5.45 and it is 5.55. Your 1/8 time should be 8.3 @85 MPH and your are at 8.5@82.6 MPH.
What kind of gas are you using? Do you get good gas in DR? Did you get a tune for your specific mods or is it a generic tune?

super-amg

yeah we have goog gas here , but too spen , but the normal gas have around 89 octane , y told jerry the octane of my gas here , and he made a tune for this octane , when i put a 100 octane gas i feel the car more slow

i have a OEM heat range spark plug , i was think buy a 1 range more cold

I run OEM plugs.

you are loosing traction on the line, you need either slicks or drag radials to cut a 1.8 60ft and it will all come together

super-amg

so , what you recomend me , for improve my trap speed , and me 1/8

Lenin

Even if you get drag radials and lighter weight wheels, you still should be faster than what you are running. Look at other people's time slips and you will see that even with 2.0sec 60ft you should still get you 12.9 or faster. 1.8 sec 60ft can get you to 12.7x or better. Only data logging can tell for sure what is wrong. I would be looking at the timing, boost, IATs and AFRs. Somehow the ECU is not giving you the full power.

Rob (Needswings), is my thinking not right here? You are the real expert.

raf12690

Yeah he definitely is not pulling like he should. I had less mods and a 2.002 60ft and had a 1/8 trap of 87+ and 1/4 mile trap at 110+. I think that he might have something holding him back, like clogged fuel filter etc. I told him he needs to datalog to really see the problem.

Super AMG. Look into getting a zeitronix zt2 wideband system with some type of display. Dashdaq is one of the better options but there are some others for better price.

Or just use the EC one, although it's not as fast and AFR isn't logged you will at least see timing, boost, etc.

super-amg

exactly you have the same 60ft mine , and you run 12.7 with 110 milles , i was think my engine have problem or something like that

i have a boost gauge aem , and the car boost 18 psi , in the morning 19 psi

super-amg

MRAMG1

Everyone here has missed the magical question, what tires are you running on?

Next, pump the fronts up to 45psi, and drop the rears to 30-22. Do not go below 20 psi for safety.

You'r 0-60ft time stink, to run into the 12's.

Buy some good tires, think Bridgstoe PP's, nitto's, or ANY tire with a treadware LOWER than 160.

Have fun

Newzchspy

In addition to DRs, look at reaction time? Driver needs some mods too!

moosejaw

What's your elevation?
Are you in the hills?

super-amg

no , im front the sea , seach autódromo mobil 1 , and see

other think i bougt a new sparkplugs 1 heat more cold , i have ik20 imgoing to install ik22 for see

Reaction time doesn't affect the 1/4 mile time at all just to let you know.

I think this is your problem....low timing from 89oct fuel Makes sense that the car is slower on 100oct running the 89oct tune. You need EC to send you a hotter tune for the 100oct and you'll be in the 12's
