I use to hit the 1/8 at 9.1 and the 1/4 at 14.8791 at 91.65

What have you changed since last time out when you got the lower times? You didn't happen to put on some 18" chrome wheels did you?

[foff667]

what mods did you add? your mph is faster then the last time out yet you say you werent spinning so im as confused as you...92mph is good enough for mid 14's with traction.

[MO6969]

all in all i have msd aftermarket coilpacks msd wires ac delco iridium plugs full exhaust including headers cool air intake shift kit running same gears been running nothing but 93 octane stock 16's same size rubber 245 50 16 and since i have last been out i have just recently added the msd coilpacks wires and plugs the temp that night was beautiful 57 with the humidity at 48 with a nice cool wind out of the north at 5-10 mph and and the way the track faces that would have pushed me instead of hurt me and then when i tried to spin the tires nothin changed them out to 205 50 15 and still nothing no service engine light i am almost wondering if there is a problem in my valvetrain and suggestions

[dmw319]

exhaust leaks? that happened to me once.

[FunkZ]

Well, 14.8 with basically just intake and exhaust is good. I see lots of 3.8's run low 15's with those mods. Still, you're right, that doesn't explain a low 16 second time, especially with those speeds. Were these runs at the same track?

[12secondv6]

Ok.... please add spaces here and there... it makes things MUCH easier to read.

So.. consistent high 14 sec car went to low 16's now.

MPH remianed constant

What were the 60;s on the high 14's vs low 16's?

I'm guessing traction issues.... but I do not know... give us more info

[MO6969]

running the same track the 60' time on the 16.2

is 2.2384 and the 14.8 60' time is 2.2107 and

there are no exhaust leaks had to get my car

checked with emisions so good on that and as far

as temp pretty close to the same when i race

maybe 1-2* difference so i have no clue any more

info you need let me know so i can get as much

help as possible.

[FunkZ]

You've got nearly the same 60' time and the same trap speed, but almost a second and a half apart? That seems impossible.

Is your tranny shifting right?

[foff667]

id like to see the two slips posted ie
60'
330'
1/8th time
1/8th mph
1000'
1/4 time
1/4 mph

so we can see where your loosing so much time...i doubt its an engine problem...i would assume tranny problem if its an auto or driver error if its a manual or slipping clutch.

yes please post a slip... sounds like its an issue going down the track, you miss a shift and forget about it ;)

[Tyler]

did you miss a shift on the 16 sec pass or something?

[FunkZ]

He said a shift kit was one of his mods so I'm assuming he's automatic.

[blacksport]

Transmission hanging up or slipping? That could explain it.
