1.6 RR & springs. CAI, EWP, weight reduction, gears, TC/Clutch, TB, TUNING.
The goal of 320ish is doable, 360 might be a tad high.

320 MAYBE doable. 360, I just can't see without heads and/or cam, and cam-only on stock heads would be tough.

Headers are definitely on the bolt-on list. EWP, if you didn't know, is electric waterpump. Pulleys, too.

Now, it ain't exactly a bolt on, but raising compression by a thinner head gasket or shaving the heads has been done before...

To get that youd need every bolt on.
That includes:
CAI Intake. Vortech,Trickflow, or 1LE Elbow. 58mm TB. 1.6 RRs. New Springs. Headers. ORY and one of the better flowing Catback. Gears
And somd damn good tuning.

I think I have just about every bolt-on possible besides RR and springs. And my full list of stuff is in my sig. I also will be going to the dyno on Saterday so if you want I can let you know what all the stuff I have on my car could possibly get you.

Depending on the weather (both temperature and humidity) low 13's high 12's are pretty easily attainable. In ideal weather mid 12's are possible.

On a stick car I honestly have no clue cause my my car is an automatic with a 3200 stall converter in it so I flash the converter at the line.

Also another thing to remember is if you want to get into the low 13's to mid 12's you'll most likely need a set of good sticky tires on your rear wheels in order to dead hook of the line.

320/330 ish is do-able if your prepared to do every freak-in bolt-on and trick known to the LT1. I made 323 rwhp / 343 rwtq with all the bolt-ons except PCM tuning and cut-out. I pretty sure the car makes over 330 rwhp / 350 rwtq with the addition of the last two mods (PCM tuning/cut-out). Car ran the numbers in the sig when it was making 323/343 and I think it's got a 12.20/30 in it at 110/111 with the additional that I picked up with the last two mods.

6 spd car with race prepped T-56 (viper snychro's, the whole 9) MOSER 12 bolt with 4:11's, Denny's Metal Matrix 3.5" polished drive shaft (weighs about 6lbs), Mcloud Street twin clutch. On the 12.61 @ 109 pass I did a 1.80 60ft on slicks and the car had more 60ft in it, but I could not hook it up at the track. Now that I've got tons of suspension stuff, I'm thinking I should be able to get into the 1.60 range. If I drop two tenths on the bottom I should pickup two tenths on the top, plus the PCM tuning and cut-out open. I'm pretty sure I can get the 12.20 range at 110/111 My car is a fully optioned 1996 WS6 T/A and everything is functional. It is a little bit on the piggy side at 3500 + lbs.

Maybe a bit more up top even.

According to the dyno, my full weight A4 94 Z28 can do a 12.20 1/4 with 275 hp... IF I could pull a 1.43 60 foot!

Those are already some great numbers the car is laying down. But to be honest looking to drop 4 tenths is a lot. I'm not saying that its impossible. But I would guess it would be more in the high 12.3's or low 12.4's Cause I agree that ET's are all in the 60 ft times but theres only so much that a N/A stock LT1 can do. But then again I'm not an expert. I'm still rollin on my stock 10 bolt with a set of 3.73's and stock drive shaft too

the dyno may say one thing........but unless you can do it on the track teh numbers don't mean anything Thats why I never bother doing a 1/4 mile simulation on the dyno cause to be honest it isnt very accurate from what I've seen.

I'm thinking 2 tenths from 60ft reduction from a 1.80 to a 1.60 hopefully and the extra 20 hp or so from the cut-out and PCM dyno-tune (another .15 tenth) I did not have when I ran my 12.61 @ 109. So, 2 tenths from the 60ft and .15 from the extra 20 hp or so, that should just let me sneak a 12.20 something into the mix. I'm guessing I will gain at least 1mph to put me over the 110 mark, maybe a touch more. If the DA and weather co-operate I'm very confident I can get the numbers I will be on a full slick mounted to a Bogart 3 piece bolted RT (very light).
