Well, it's very cold out and the car isn't quite finished so let's hear your thoughts. Pending the arrival of a couple small parts this week, I may finish it (are they really ever finished?) and start it this weekend after a long winter of changing parts. I should be able to get out (weather pending) in mid-February but wanted to hear everyone's opinion before then. Here's what I have ...

'94 A4 Formula with 130,000 miles

Stock LT1 other than fresh valve springs (no roller rockers, TB, etc.)
Ed Wright tuning
Pacesetter 1.75" LTs with 3" Dynomax race mufflers (no cats)
CPT Pro Race 4L60E & Vig 3400
Moser 12-bolt with 4.30 gears
QA1 shocks and springs on the front
stock rear suspension with bolt-on traction bars from a Super Stock racer
Weld Wheels with Moroso fronts and Hoosier 28" drag radials
MSD opti
Accel wires with NGK plugs
Fresh O2 sensors, fluids, filters, blah, blah, blah ...

Weight removal including AC, PS, EGR, AIR, sway bar, etc. delete
Race weight (with driver) will be just over #3300

Assuming it will hook, and considering I'm fortunate enough to live in Eastern NC where track DA is often below sea level this time of year, what are your predictions? My index for IHRA C/PS is 12.75 and I'm hoping, under perfect conditions, once I have it sorted out, it will have an 11.999 in it.

 

im guessing around 11.99 but who ever knows for sure lol.....i hope some day i can hit high 11's just like urself...i have ur same plan in mind! please post ur times after...i am real interested in seeing them

 

You asking alot out of a stock motor. What kind of race weight are we talking?

 

#3320 is the minimum weight for the class I'll run. I've removed a bunch of weight though and I'll be able to move it to the back (gas, 12-bolt) to come up with that weight.

 

I'm not thinking you are there yet... With the stock valvtrain the stall will not be as effective, but the tranny should be quite efficient. The 12 bolt is great. The gears are great, but I think youy be running out of rpms at the top end. The 28" tires are good but I'm still thinking you are in the mid-high 12s.

When my Camaro was pretty much stock it would turn 13.5-13.6 with drag radials, shifter, headers and cold air... If the stall and gears take off .5-.7 in ET that is 12.8, and if losing 300 pounds drops it to 12.5, you still have a ways to go... Having the taller tires might help the gears eek out another tenth but I'm thinking you need to do something to generate a tad more power...

 

run a 28" tire on it. she's going to be pissed off on the big end with a 26".
should go a low 12 MAYBE a high 11.
get another 200lbs out of it and she'll be fast!!

 

i have faith in ya man!!! 11.99's!!!!!

 

What I'm basing this on was my bolt-on Impala SS that was basically set-up the same way and ran 12.80s at 4000 lbs. Subtract 700 lbs. and 0.7 and you get low 12s. Of course though, "drag racing" math doesn't always work out that way.

 

11.99-12.4 i bet weather and track prep depending

 

You and I have talked about this before, but I’m more interested in your trap RPM w/ the 4.30s and 28” slicks. Again, I’m going to the same combination this year.

On the possible ET. When I was doing bolt-on’s my LT didn’t really “come-to-life” until I added the cam and increased the RPM and torque curve. The next best upgrade was the Vigilante 3200.

My ET prediction is mid 12s (maybe 12.30s) with the upgrades you currently have. Also, let me know about the trap RPM.
