Good times for your mods especially it being a 98 car with i'm guessing still the stock ls1 manifold... on a shitty 1.9 sixty foot I went 12.57 @ 110.51 mph. with mods in sig. except the Yank PT3800...

 

do your 373s whine a little bit

 

wow very impressive with these a4 guys. those are some low *** 60's

 

i think his trap was like 109, the car just pulls so hard i cannot keep my foot off the gas, next year i will do a fast 78 with a ported TB, pully, and switch to 410's. i think this should get me to the high 11's or low 12''s.

 

congrats man!

 

Thats pretty impressive

 

my old 00 formula a4 went 12.7 at 108 with a lid, random tech cat back, ported tb, HPP and 160 stat & plugwires, some suspension on nittos with a 1.8 60ft. Car was otherwise stock. After that I put in a Vig 3800 but never made it back to the track with it. Sold it for a truck

 

Yeah those times seem pretty solid i have around the same setup. So what do you guys think are the best shifting points for each gear. My shifting points are also somewhat high like 6400 out of 1st gear.

 

The stock cam peaks around 5300-5500. Shifting at 6000-6100 is more than enough, shifting at 6300+ (with stock internals) is just prematurely killing your transmission for no gain.

 

Nice avatar! thats my old car, Its cool to see people using that pic.
check the link in my sig for a video of it.

I borrowed my buddies superchips tuner last night, got it down to 6000. That thing is actually pretty decent, i mean its prob not s nice as a true tuning job, but it fixed my problem.

 

Thats funny bro! Ya shes deffinently got a hot body! The link in your sig didnt work for me though... I WANT MORE PICS! lol

 

Here's a comparison of your mods and my mods from last year


1998 Camaro Z28--------------99 Formula
Stock Supspension-------------Same
Stock Rear w/ 3.73 Gears------3.23 gears
Yank SS3600------------------TCI 3500
Lid----------------------------same
Headers w/ Dual Cutouts-------LT's with bullet in I-pipe
Radials------------------------M/T street radials
-------------------------------ported TB
-------------------------------SSRA

6500 is way too high. 6000 is fine for a stock internal LS1 since the power really drops off after that.

My best pass with that setup was 12.31 @ 109 on a 1.65 60' at NYIRP in western New York.

 

Thanks a lot man!

It was hosted on videos.ls1tech and it looks like the sites down, I'm at work now but i'll fix it once i get home

 

My 02 SS a4 w/ just LT headers,stock cat back,stock converter,Hypertech tune,underdrive puley,LCA,PHB,STB on MT ET streets ran 12.61@111 w/ 1.91 60ft.Thats @ sea level your car would a couple of 10ths faster in Florida than New Hamrshire.

 

Those are great times man, especially for what your car has. Don't worry about the 10 bolt, I have had 2 H/C A4 cars before this one, first went 12.0's, second went 11.60 with a 1.60 60' both on the stock 10 bolts. This car went 11.00 on the brakes hard, no idea on the 60 but it leaves HARD and its fine.

 

turns out Videos.ls1tech turned into LSX.streetfire so my link quit working heres the correct one

And to the original thread poster your car runs good, and i wouldnt be worried about the rearend. my 10sec A4 consistently saw nitrous out of the hole on slicks and never broke anything. A4s are able to make the 10bolt last alot longer then the M6 guys can lol
