14.73 1/4 mile time.....whats wrong with this picture?

[Sbeing1]

I went to the track last night and pulled a 14.73 quarter mile time (forgot the trap speed). i dont get it, is my auto weighing me down this much?! or is it because i dont have a safc and injectors? any help is appreciated. my mods are...
Super 16G Turbo TDO5H,
1g BOV,
MBC,
Injen Intake,
Greddy 3" Cat Back,
Greddy CAT,
Walbro 255 Fuel Pump,
Boost Gauge,
Air/Fuel Gauge
new plugs, oil, and boost leak test all good

i just dont get it. I thought id be in the low 13's easy. Maybe auto is to blame? would high stall torque converter put me in 13's? My car is super slow at the beginning and i dont get boost till maybe second gear or high 1st gear, so my launches are as slow as a civic till boost kicks in.

Have you checked for any boost leaks. Post up your full Timeslip like 60ft, 1/8 mile and 1/4 mile and trap speeds as well. It will help to diagnose where you are losing power at. Also do you have a FPR for your fuel pump? Do you have a Datalogger? Answer these questions and it will help people to help you...your Air/fuel is probably all messed up

Yeah I'm not sure what that pump is doing for you without injectors, an AFPR or an AFC. Do you have a logger? You are probably running ungodly rich, which would mean I could probably take you in a shopping cart. That turbo isn't making things any easier either. Basically your air and fuel are all out of whack.

Bingo. It's all about tuning and matching the right parts together. Loved the shopping cart line the best though.

In all seriousness:

1. Log it
2. Check for boost leaks
3. Add injectors and fuel control (AFPR, etc) or step down to a 190 pump
4. Post the time slip
5. Tell us how much boost you were running

Cookies to doughnuts says it's the 255 and no AFPR that's killing the A/F ratios. I'll bet your drowning at levels below 9.5:1 from all of the excess fuel. You might want to pull a plug, take a picture and post it so we can read it for you.

Get back to us and we'll see if we can help.

I'd like to add that although I don't know that much about autos, you should see low 13's once you are set up correctly, if not better. There have to be threads on here about launching auto AWD's, check around. You should be building boost at the line, the advantage of autos. You should be flying out of the hole!

Wow! fast responses! no i dont have a afpr, or any logger and Ive never tuned my car ever. I just changed my spark plugs (is that what you mean by pull a plug and take pic) i still have the old ones if thats the case, i can take a pic today. I already did a boost leak test and the only place i didnt fix the leak at was in the throttle body (that o ring). also im running 16psi (ran 21psi accientally a week ago, found out it was set at 16psi then i fixed the leaks and didnt change the mbc down and i ran 21psi, hope that didnt do anything) i lost the timeslip, i only rememeber it was a 14.73 1/4 mile. but i can tell you my launches are sooo slow. ill get a video of it and you guys can see, its slower than you think. then when boost kicks in it runs o-k i guess.

just checked to see if i still had my old plugs but my dad threw them away. but i remeber they were pretty brown and the white peice in the middle of the plug (bottm of the metal peice that cunducts elcetricity) was shatteres on all my plugs. i dont know if this helps

lookes like this but a little browner...

also, my air fuel gauge ( i dont know how to read it) it goes from left to right, it fluctuates from red (far left) to almost mid green and back to red.

If that thing is shattered it's because the car is knocking, how much boost are you trying to run on the stock injectors? WTF

 

[92awddsm]

That plug you posted has been subjected to detonation so if yours looked like that, thats bad. Turn your boost down, get injectors, afpr, afc or maft, and a logger and then start over. Keep up at the rate you have been, you will be spending your money on a new engine instead of the mods you want. Also with plugs like that, I would do a compression test and see if you still have any. Plugs like that tend to lead to broken rings, burnt valves, and pistons.

 

[Sbeing1]

thing is i just bought the car, has 114k miles. Im guessing the previous owner beat on it a bit. But i turned down the boost now. so how do 750cc or so injectors, a afpr with gauge (any specific i should get?) and a safc. will that make me run the times the car is capable of?

 

[Sbeing1]

also, i did a compression test and they were all about 140-145

That compression is pretty low. Try it again with the car up to temp and then add a capful of oil to each cylinder and redo again. That will give you a better idea of the condition.

If you plan to tune with only an afc, you shouldnt go any larger than a 650cc injector. The afc doesnt have enough adjustment to properly control anything larger and timing will also go nuts trying to compensate for something that big. I would also reccomend sending your eprom ecu(I am assuming its eprom since you have a 95) to Jeff O. at dsmchips.com for a socket and eprom with compensation for whatever injector you plan to run. He can also mod the eprom to display knock values on the factory boost gauge so you can prvent something like this from happening again.

 

[Sbeing1]

that sounds like a great idea, thanks alot! i guess that will be my next step, thats sounds really good, they actually prgram it to my specific injector? awesome. also,I have one more question, this may seem stupid, but where is the factory boos gauge? , i have a aftermarket one on my a pillar and i dont think ive seen a stock one anywhere.

The factory gauge is located on the smaller gauge on the left and below your tach.

I think you're on the right track by re-doing compression. While you're there, make sure that ALL of the preventive maintenance has been done including timing belt, balance shaft belt, tensioners, idlers and water pump. Change out all of the fluids in the transmission and make sure she's in a good state of tune.

As far as what you're thinking in terms of injectors, those are out of the correction range of an AFC and you'll never be able to lean out enough to make them work for you. I would recommend 550's or 650's on a 16G. If I were you, I'd ditch the 255 pump and use a 190 instead since the overrun is mild enough not to cause an overly rich condition.

Keep your tuning simple and effective and you'll have the best results.

Great advice there. I would certainly listen to it and also consider that you can have Jeff make you custom airflow and timing maps that will make an AFC a requirement of the past.

When you get to that phase, let me know and I'll help you with all of your parameters.

Cheers!

[Sbeing1]

great thanks alot guys!!!! i will follow your guys steps to a t. ive already done all the preventative maintanence so i guess im ready.

 

[pianoman]

How about a 3inch downpipe to help get that turbo spooling. That is a hahn super 16g with the 10cm housing is it not?

 

[Sbeing1]

i really have no idea, guy i bought it from said it is a super 16g turbo, i know for a fact its a 16g but i cant tell who made it or if its big or small
