my car is stock and i thought i would get a higher mph/better time with the cold temps - this was my second time at the track with this car and i wanna know what time/speed you guys think i should have run with better numbers? where did i lose speed?

R/T .335
60' 1.967
330 5.406
1/8 8.223
MPH 87.21
1000 10.648
1/4 12.688
MPH 110.94

Just like benz said the first thing is to change intercooler pump, it looks like ur car is dying up top u only do 87 mph in the 8th

are you on street tires? from the looks of your 60' did you spin the tires causing your ECU to cut power? because after once you got rolling your #numbers look good

i was running 25 psi in conti pro contact 2's and didnt spin too much. it felt like the power was fading when i was in the top end.

ok then just as Benz O & Infiniti said change your IC Pump with a Johnson CM30 or Meziere wp136

i was reading about density altitude and today it was -2100 at MIR, so calculated that makes my 12.6 actually a 12.9 - bad h/e pump seems logical. does the h/e pump quit pumping all together or just become weak? i will replace it next week just to be done with it but here's my my newb question, if i had a good pump would i've run closer to a 12.1 - 12.2 instead? or even better than that because of the DA?

12.6 with a 2 second 60 ft is not bad at all,if you would cut a 1.7 60 you would of ran a 12.0 1/4 mile.I gave up on trap speeds since at my track every stock e55 is gettin 111-113 and my 500whp car only traps 121 here.

12.6 with a horrible 60ft is awesome!!!

Also did you have the car in s2 and in SD on the dash? The car will short shift gears if you don't run it this way.I pick up 1.5-2 mph from just keeping the car in drive instead of having it say S1 ect.

Replacing the stock pump would be a great and cheap start to figuring out why your car is trapping lower than usual. You should also consider purchasing a cheap data logger to log your IAT's. Diagnosing the problem would be much easier and eliminate a ton of guessing.

Racing in -2100 DA is extremely rare and it's probably some of the best conditions you'll see. I would kill to have that kind of DA to race in, especially a well prepped track like MIR. Good luck and get back out there!

You should take your car to Atco and run with Loco. His car has been doing extremely.....

His car is running awesome!!! I think Im done for the season,I wont be able to get my TB on in time and the ecu needs a few tweaks still.I would love to run with him sometime though but I know it will just push to go with a bigger pulley and turn the car into a dragster.I swore I wouldnt mod this as much as my M-power but that didnt last long lol.

I can't enjoy it now with this cold weather we have.When I say first and second is useless I mean its useless,its like punching it in the rain.I havnt got on boost in the first 2 gears in almost a month and 3rd gear is blah lol.

I miss stock pulley and cold weather,I could nail first and second and get full traction!!! 23D out tonight and had to baby the thing home.
