Approx what would a 500hp A4 2.56 c4 do in the 1/4 mile?

Youd be crippling yourself with the stock gearing...

That Golen engine is really only going to be ~430 hp as installed. That should be good for very high 11's. That gear would hurt your 60, which will directly hurt your ET (but not your trap)....so, I'm going to say mid 12's with a decent converter.

I would guess anywhere from 12.2-12.5. That is, until the Dana 36 breaks. If you're running 500hp, you really should upgrade to a Dana 44.
Find out from the engine builder, what gear ratio they recommend. Most standard gears are 3.45. Maybe 11.9 -12.1 after that.
It will take practice to launch without a lot of wheel spin.

The cam it takes to make that may not like that gear, your converter wil be slipping too. Wont run the way youd think it would

The answer is not what the hp will get you, it is how to use the hp.
Stall, gears, and planned trap speed have to be taken in to consideration.
Are you just looking at improving the car? The hp will feel better, but what parts?
A 2,59 gear will not do well with a higher revving cam and in intake platform. The stall will affect those things as well.
You can drop it in and it will run, but it might be terrible and act terrible. Most likely it will. Meaning it might be more boggy than stock motor until it gets in to its happy range, and any little block making any hp is making it higher up closer to 25-3k for sure.
I think a proper burnout while at the tree and let it fly while the tires are still spinning she will work great. LOL all about timing. j/k
Edit: I see it was already addressed.

I actually gave Golan engines very serious consideration and my car has the same 259 gear. I wasn't interested in quarter mile performance though. I was looking for 70 mph to 150 mph performance, and I think Golan engines would be perfect for that.
At one point I had started a thread about Golan engines but Pheonix97 messed it up ....

Unless you're tracking it constantly the 36 is fine. You probably don't need 3.73 either. 3.3 something or 3.42 would probably be fine.

The goal for the car is basically more HP.. When I drive the car ALOT of people are punking me. I tell myself, well "..this is just a clean A4 2.56 cruiser car. I have a LT4 w 4:10s for when I feel the need for speed.." But that thought is waning to my thoughts of different things I can do to make it more on par with current sports cars. The golen engine has a very attractive price tag to me.
The stock cam is a small cam and is built for low range and higher torque in the mid range. To get higher HP you will have a larger cam. The 383 will make up a little for that but not much. Better off finding a used 3.07 diff and installing. New gears and install cost a lot.
i have had and tried all kinds of c4;s and gears. Big difference with a 3.07. Anything higher up to 3.73 is ok if you have an lt1. If you want fun in a l98 no lower then 3.54. I forgot what year this one is.
You have the wrong car for not getting punked.
I have a decent sized motor and cam, gears and stall matter even with it making silly torque or hp.
For example my current set up is: TC is set for 52mph, but my cam is not happy in OD unless 65ish-70 is happy. This is with 3.45 gears and it lugs. I need lower gears. 3.73-3.90.
your car will do the same but worse. Gears are the answer or gears and motor

To be honest, it is fine to add more power, again it will NOT respond well.

Tax season is right around the corner and Im going to spend some money on my cars..
Id like to Stage 3 transmission from Pacific Coast Transmissions in Lomita ($3k) and/or Paint the black car ($3k).. Seeing the price of ~ $8k for crate motor seems doable, but I know in reality when its said and done that project will prob cost more like $13k when all said and done.
