I think my next pass was 12.740 @110 1.9 60'

murphinator May 11, 2017 09:17 PM

nice , bigger gain in trap than I expected , nailed the et though , well I was off by .016 lol.

That trap and 60 foot say you are making the power to go bottom 12's if you can fix that 60 foot time - time for a convertor

Allstock02 May 11, 2017 09:21 PM

Yeah I want a stall but just haven't pulled the trigger yet. Shooting for 12.6 so I can race a money class

Cahill93Z28 May 16, 2017 10:23 AM

That's a good time for 2.73's, nice

Allstock02 May 17, 2017 10:09 AM

well its that time of the week again weather looks good 75 this evening and the DA is 1287 at 5pm and 800 at 8pm, just maybe ill get 12.699999, you never know. guna play with the launch and do a better burnout to try to leave harder will see.

I see you have free mods listed, do you have the air box bottom cut out? It would be worth it to get a SSRA or chrs1313 ram air duct and seal the front of your air box. That's worth around 2 mph

Allstock02 May 17, 2017 11:20 AM

Yes it's cut, how dose the ssra affect cooling sense it is in front of the radiator

I run the Chris1313 on my car and I can confirm it is totally worth it. I have not noticed a difference at all with the cooling. Overall it's been great, you will find that some of the cutting can be a bitch to get everything right. Great product still imo.

Allstock02 May 17, 2017 12:35 PM

what all did you have to cut? where can I buy one only ebay?

Ls1Ryan2002 May 17, 2017 01:36 PM

I started to have to trim the bumper support when I decided it was just best to remove all of the support anyway. Other than that I had to trim a bit of the radiator support (Nothing major) then I used some self - tap screws and sealed everything together. I enjoy it because you really don't notice it at all for the most part. When you start it up you can hear it sucking in air and it's pretty badass. They are proven to make quite a difference. You can find them used, I see them for sale on here quite often. I don't recall where I exactly got mine, It was a Black Friday sale. I believe it was off of the SpeedInc website. As of right now they are $200. I have the non - ac. But I've seen people say they didn't see much of a difference from Non - ac to the ac version. Here is a link from where I purchased mine. http://www.speedinc.com/shop-by-manu...3-ram-air.html

Allstock02 May 17, 2017 02:31 PM

yeah I will have to pick one up or look into making on myself, id like to be a solid 12.6. that would be real good for a car with lil mods on it.

fst100 May 17, 2017 02:45 PM

what RPM are you brake-torqueing, if you are? I'm so tempted now to go to the track this season. also what PSI are you running? deep/long burnout or just a quick blip to clean the tires off?

Allstock02 May 17, 2017 02:56 PM

my best 60' was off idle (1.9). Before I got nittos I was hitting 2.0 launching at 900-1100. I ran my nittos last week at 28psi (woops) they did spin a lil, going to 18psi tonight. I did a mild burnout but will be doing a longer one tonight( waiting until I see smoke). everything depend on the track too. my local track has been having big events on Sundays so I hooks good early on wensdays.

gesto May 17, 2017 04:07 PM

If you can, open the hood and let the car cool down for a while then push it and don't start it until right before you pull into the burnout box -- especially if your tune has stock IAT timing pull. You might pick up a 10th or two.

My theory is the stock tune pulls timing for IAT if the car idles and the sensor gets hot. The sensor doesn't react to the temp change fast enough when you leave the line so it's pulling timing the first couple of seconds.

I did this last Friday when the D/A was in the 1350 - 1375 range, air temp of about 76 degrees. There was a track shutdown for about an hour allowing the car to cool down and then pushed and started right before moving into the burnout box. The car picked up 0.07 60' and 4 tenths in the quarter while only picking up only 0.8 mph. Some of the ET decrease was multiplied by nitrous but the 60' was not.
