explain to me why my best time is 13.5@101 with a 1.9 60 ft?

last night my best time was 13.8@99 with a 2.0 60ft!!

temperature and humidity play a part i know, but it was cool last night (around 72-74) and the humidity was relatively low...

i hear cats running mid 12s with this setup!!

i know the car needs to be dyno tuned for the best results, but come on, at least a 12.9!!

 

Your car needs to be tuned to good run 12s. What is your "conservative" tune? What a/f ratios and timing are you running?

 

i don't have the timing harness in yet.. no wideband, but a friend of mine does sr20 swaps and turbo kits for sentras... he just took out some fuel towards the high rpms... i felt a difference from stock... like i said, it needs to be dyno tuned.. but that shouldn't be the ONLY thing wrong

 

My stock Evo's faster than that...hmmm, that sucks man. Can't realy help though, sorry.

 

Without any datalogs, you have no idea what's going on inside the ECU. I would guess you're detonating and losing timing. That is why your car is slow for the mods it has. What octane gas were you running?

 

93 octane...

 

Tuning is EVERYTHING

 

liek he said Tuning is everything. I would recommed getting a professional tuner to take a crack at your ECU, not sure if you live near Vishnu, or Boost Solutions, or Dynoflash, Works, TT, those guys could get you running right. I wouldn't have someone that wasn;t overly familiar with our Exacr cars foolin around with the ECU! Good Luck. You may want to try at least a mail-in flash

 

i was thinking Turbochargers.com or fi-systems.com to dyno tune with the E-Manage... i don't want to get rid of the E-manage because doing a flash would defeat the purpose of me buying it... nobody in Louisiana has an AWD dyno so my nearest bet is Houston... i have some family that lives there so it would also be conveinent (sp?)

anybody have experience with these 2 companies?

 

Could be your clutch since it's stock right? I've heard all over the forums that the stock clutch is crap, specially for drag racing.
But yea I agree tuning is really important, especially when you start getting into the tunable ECU's. Got a fuel regulator?

 

it's not the clutch... no fuel regulator..

 

try a mail flash or following a tuner upgrade path... something is seriously wrong with your setup...

 

I feel like my stock clutch isn't holding after my mods, although I seem to be the only person that thinks this...

 

It's quite simple, your not driving good, 1.9 and 2.0 60FT times are not very good, and I can only imagine how bad your shifting is? I mean, this may be hard to hear, but maybe it's not your cars fault but your fault. Tuning? What? You definitly have enough to run 12s, and just because his car may not be tuned it doesn't mean he is gonna run slower than stock, so what are you people talking about??? One last thing, there could be problems with your car, I would get it dynoed to make sure you are laying down the power you should be laying down. If the dyno goes well, then it's your driving, practice makes perfect. I shaved almost a whole second off my VR4s time with just more experience and better driving.

 

Maybe having Travis (if that's who you are reffering to) not touching a 4G63 when he blows up QR25 motors will help...but if it is not Travis, then disregard what I am saying because I am a moron...but if I am correct...TAKE THE CAR FAR, FAR AWAY FROM HIM!!
