I dont know either man, but I was having a similar problem out at Houston Raceway Sunday night. My best run was 12.047@117.46 with a hundred shot but my sixty foot time was no better than1.958 all night long and I have front runners with 26x10.5x15 MT ET Streets. I know my next mod will be a torque converter..my buddy with a 3500stall was cutting 1.6 60fters. I know I should be in the 11s I was running 13.8 N\A on nittos and a 100shot should atleast take off a full sec plus the front runners should help out and the et streets are cutting the same 60ft times as my nittos but worse...does not make sense... I was really getting frustrated!! People kept telling me it was my tire pressure but now that i look at my slips ...the time got worse as i lowered the press. After reading that post about the endlinks and unbolting them i just remembered hell i took my entire swaybar of when i was running the 12.8s N\A and my sixty foot times were better....This friday its coming off again!!!! GOOD LUCK MAN!!!

 

Fresh plugs, preferbly Delco or NGK, gapped at .035. At .060, you might be blowing out the spark. Also, I can't believe no one said anything about tuning. HP Tuners is a wonderful tool if you know how to use it. Lose shift delay, and torque management. You'll pick up a couple tenths there. Take unnecesary weight out of the car as well.

BIG Thanks to Scott at WWW.NITROUSDIRECT.COM for a SUPER deal!

Ok, well I can guarantee you are knocking. SLP Maf does not work well with spray, also the IAT mod is preventing you from receiving proper fueling. Also, lose the heavy C5 wheels. If they are repros, they're way heavy. Some of the stuff you are doing here is counterintuitive.

 

These are my new and only mods. The wheels are OEM GM
my 98 a4 T/A mods are exactly: WS6 hood,FRA mod, TB bypass, Lid, filter, bellow, Borla exhaust w/o plate and 555r D/R's
Plugs: NGK TR6 4177 gapped at .36

 

I do have a K&N, and my buddy oiled it up last. But he's real picky about how it's oiled. Im going to pull it out to check anyways.
Thanks

 

Cool, I wouldn't want to see someone pop a motor because of the previous combo listed. Your altitude plays a big effect, and your 98 heads are holding you back. As a reference point, my 00 241 headed Formula went 13.60 @ 102-3 bone stock. With an SLP lid, Magnaflow catback and tuning went 13.000@106. Adding a converter and rear hal's took it down to 12.20 @109.

Have you done any preventative maintainence? Fuel filter and the ilk?

 

the track is about 560FT. in altitude
The heads in a 98 are different then 99 and up?

 

60 foot FTMFW!

 

I agree that it's the 60' also. I know when I would run on my street wheels and tires (17x11's with 315 nitto 555 drag raidials) I'd have to drop the tire pressure to 15 lbs and heat them up pretty good.

 

Whats 60 foot FTMFW, mean?

 

I would not use the nitrous until you know the bottle pressure. stall = quicker 60 + engine stays in the desired racing rpm throughout the rpm range ,shift kit= more line pressure , less heat and a longer lasting trans , less clutch slippage , TUNE and a aftermarket Transmission cooler = once again less heat, heat is the enemy . Do those following mods and you will be spanking ***

 

60' 2.164

That is your sixty foot from your timeslip above , dragstrips timing devices measure at different points 60ft , 330 1/8mile ,1000ft ,1/4 mile


60' Time - Time it takes a vehicle to travel the first 60' of the track. Good 60' time is a crucial to achieving superior elapsed times. It is a good indicator of above average driving skills.

 

my buddy in his 01 ws6 first time at the track, got a better 60' than me on street tires. he was cutting 2.068 60 footer's

 

When i was trying out my nittos on 18-20 psi my car was loosing major top end.. i bumped em up to 25psi and that seemed to really help out on the top end.

 

what kind of 60' would you get on 18-20psi vs 25psi?

 

im looking at all my time slips from the past couple months, and it looks like all my 60' are above slower than 2.1XX.
the best 60' that I have done is in my sig
the only difference is that on this run i drove around the waterbox and then backed up into the damped area, but still my buddy was drivng through the waterbox and cutting better 60' than me.
60' 2.099
13.7 @ 102

 

Work on your 60'. It's way high. If you get the 60' down to 1.8, you'll break into the 12's.

 

any pointers?

i have nitto D/Rs 285/35/18

 

 

If you don't have a n20 gauge you have no idea what your n20 to fuel ratio is. You could be low on pressure even on a full bottle because its cold out and be running pig rich. Or worse its a hot afternoon and your bottle pressure is sky high and you lean your motor to much and its toast. This would be like FI car with no boost gauge. You gotta have one to know whats go in on.
