ran at rock falls times are a bit slow?

[cudvig]

I think my car is messed up? I ran a 14.4 at 80 MPH with a 1.9 60'

but i also ran a 14.1 at 92 MPH with a 1.9 60' the first one was on 16 PSI and the other was on 22 PSI

With my mods, i should be in the mid 13s or so?

right?

I have 3 inch turbo back, rewired fuel pump, datalogger, intake filter, MBC was at 16 and 22 psi both were on race gas, UICP, larger outlet off compressor, ported 2g manifold and o2 Housing, and a southbend DXD/TZ combo clutch. that should be good for more than what i was trapping at?

[Onefast99gsx]

turbo size is listed where?? I don't see it in your list anywhere.

[AJ]

Your sig says you are waiting for dsmlink for the 1Gs to come out (which I think is already out) so I assume you have a 1G with a 14b still?

Yeah, you need something fixed in that setup, unless with the temps being what they are today you may have just heat soaked the fuck out fo the stock IC. On a day like today a FMIC works fucking wonders over a stock side mount. Sounds like a good tune and a cooler day is all you would probably need for an improvement of a full second at least.

14.4 @ 80 is pretty slow. You probably got out of the hole ok, did you let off? Did your car seem to die up top? I had a similar issue last year. Car seemed like it was heat soaking and seriously lost power at the top of 3rd and all through 4th.

[Shane@DBPerformance]

Post up the entire timeslip.

Your traps are way too low. Cher and Mara were running 12s and trapping in the 106-109 range with the same mods and a couple more psi of boost.

[JET]

Yeah, something is off. Like Shane said, post up the whole slip. My DD talon had a MBC, K&N, wires, UICP and ghetto 2.5" cat back and ran 13.6 @ 99 on ~ 16 psi and pump gas at full weight. You should be high 12's at least.

How's your shifting doing? You must be taking too long during shifts or not shifting at the right RPMs.

[cudvig]

i shifted quick enough i think? and i missed 4th on that 80 MPH one. I also shifted at like over 7000 in 1-2 and near 7000 2-3 and at like 6500 3-4 does that work for shifting?

[JET]

That is pretty high shifts for a 14b. The 1-2 is ok, but after that shift more around 6500. Has your car been tuned?

It looks like you need some tuning. You are down on power the whole way down the track.

There has to be a misprint unless you let off or hit the breaks on the first run. It took you 3 seconds to gain 3mph in the end but on the 2nd run it only took you 3 seconds to gain almost 20mph? I bet there is a misprint and its suppose to be 89.65mph or something, cause compairing it to the 2nd run, things just dont seem right.

[SuperSleeper]

i think i missed 4th gear on the 80 MPH run most likely

Yes he did miss fourth.

[cudvig]

But all i have are some bolt ons? why would i need tuning? I know it might help but not a whole second. I think my plugs are old and now i have a huge ass boost leak.

[Shane@DBPerformance]

Bolt-ons can make a huge difference in the tune also. The car is tuned from the factory to run with a stock exhaust at stock boost levels. The more airflow the ECU sees, the more it overcompensates with the fueling. Some people can run fast without any tuning device because the MAF screws up and overruns and doesn't actually get a correct reading of the airflow and the car doesn't go insanely rich, or they don't have enough fuel pump or injector, which can help lean it out. Or if the MAF messes up too much, you go too lean and knock. What did the datalogger say for knock? Have you checked for boost leaks? They are main cause of mysteriously low power.

[cudvig]

my data logger displayed like no knock, sometimes i would get a 1 or something. My timing was at about 20-21 at 6000+ RPM. I think its boost leak since i have a huge one now, it wont let me boost past 10 without become way rich and stuttering. I might just go ahead and get some new piping, and maybe some new wires? they are old anyway.
Ill post if/when i find that leak.

thanks for the help

Well, I assume you would have noticed the car not boosting past 10 and concluded that was the problem at the track. IMO, wires are wires. As long as they deliver spark, they are good enough. I would do a boost leak test to fix the new leak but I do not think that was your problem at the track if you could boost to 20 psi. Usually with a boost leak you will knock. If I were getting 1 count of knock, I would have upped the boost more. 1=0. Might want to check the plug gap or replace the plugs as maintenece.

[JET]

If you have a problem with plugs/wires you are going to hear it. The car is going to be missing badly. The problem probably was a boost leak of something. Maybe you just have it tuned way too rich or something?

[niterydr]

My question is...why is everyone assuming he 'tuned it'? Where are his mods that will physically allow him to tune it?
My guess would be boost leak. Start there, then move on to the air/fuel mixture.
The car seems healthy from what he posted from the datalog's (for info) just a little flat, which would lead me to assume its not getting full power due to heatsoak/boost leak, not a overly rich/lean condition. Plugs could also be an issue, like mentioned, but as Jet said, you would hear that and feel it.
