Bad day at the dragstrip!
Was searching for a 14 second 1/4 mile when I went to Englishtown today. Only got in two runs. First run I ran a 15.8@86mph. This was Chike's car previously and he was running a 15.0 1/4 mile. The temperature outside was around 44 degrees F so hot air wasn't the problem.
My 2nd and final run I was staged against an Acura RSX. On the last yellow light, I went to floor the gas pedal and the car died. :eek: This has never happened before and I could not duplicate the problem afterwards but it died on the line. I turned the ignition off and turned it back on and took off. I did not get a time for that run for some reason. I know my 19" rims are part of the reason my time sucks. The wheels are three sizes higher than the lightweight RX7 wheels I have in my basement. I may put them on next time. I decided to stop while I was ahead before something else happened. Sorry I could not represent the SVX community. :( People did like the car though. |
You might wanna preload the tranny next time you floor it from a stop with those huge wheels on.
-- I cannot fathom the source of your stalling problem. |
It wasn't your day. That happens sometimes. :o

Kevin,
I agree that your rims are a major part of the problem here. Another thing to consider is that Chike is a skinny guy:rolleyes: :p -Bill seriously, how much gas did you have in the tank and how much heavier do you think you are than Chike? |
you were at e-town and didn't tell the Jersey crew? :(

I had a little less than 1/4 of a tank of gas. I weigh around 208lbs. Chike is around 160 something if I remember correctly. Yeah, that doesn't help things. :D Quote:

Okay, if we use the old 100#=.1 second rule, we might have .2 of a second worth of the problem. Wasn't Chike's 15.06 before he installed the cams? (not to say the cams are a problem, just trying to establish a baseline). I also remember that Chike always removed the passenger's side front corner to allow air to flow into what's left of the air box in the wheel well. Even if you didn't do that, I doubt it would be worth more than a .1 anyway. My sense is that there is something else going on. What was your 60' time? -Bill |

I would also brake and bring the trans up to stall speed before launching. I got consistent 2.1 60ft times this way. |

I would LOVE to do this. Two things bother me though. 1) The clicking axle problem, 2)No tranny cooler. I am a HUGE fan of a tranny cooler. Somehow I feel if I start brake torquing this car, I'm going to start having issues. I know how to brake torque since I have been doing it for years. I am just a little concerned on this car since it doesn't have a tranny cooler. I didn't brake torque properly the first time. The throttle response threw me off and was so snappy, I thought I was going to red light. I let off, hit it again and still redlighted. :p I know this is irrelevant to the whole 1/4 mile thing though but I was bracket racing. Will see about swapping out the rims to see what affect it has. Here are the drag slip details. Reaction: -.172 60': 2.304 330: 6.556 1/8: 10.089 MPH: 68.68 1000: 13.188 1/4: 15.802 MPH: 86.34 |
Chike Bob's theory is brake torqueing reduces the impact of a sudden leaden take off.
I think if you take it to 1k or so you can be good and not worry about heat issues. But with the massive rims, I think more harm would be done by not preloading the converter even slightly. Your 60' is faster than mine. Everything up to the 1/8th is, but your 1/8th trap is somehow 2.7mph slower. Seems in comparison you lost mid range, so I wanna say the hugenormous wheels did more damage then your 40lbs or so of Myxalweight. Picked up .5mph by the 1/4. ___60': 2.304___2.465___-0.161 faster __330: 6.556___6.669____-0.113 faster, slowing _1/8: 10.089___10.142___-0.053 faster, slowing _MPH: 68.68___71.410___-2.730__---- _1/4: 15.802___15.627___+0.175 slower, gaining _MPH: 86.34___88.560___+2.220__---- |

Couple other questions: 1) Did you use the factory intake set-up with the STI panel filter? 2) Did you do the rudimentary MAF bypass mod? We know the car is making 170-175whp depending on which correction scale is used, so power should not be an issue. Not sure what caused the stalling, but I'd check simple things like the ATF level in your trans. |
sell those bigass bling blings and get some smaller wheels
|
my car stalled exactly like that at a stop-light when i was jokin around with a friend... i stomped on it and it killed... pretty funny at the time, didnt think much of it though..
|
Any light blue smoke or gassy smell starting up after the stall?
I wonder if there was a sudden massive vacuum loss. |
nothin of the sorts for me... cant vouch for him though...
