I have a 93 z28 a4, current mods are a flowmaster 2 chamber muffler, high flow catalytic converter, airhog airfilter, all royal purple fluids, air foil, throttlebody bypass, fusion zr1 tires (new). I was wanting to break 13s in the 1/4, whatdaya think? Im getting a shift kit soon, but i may run before i get the shift kit.

prolly around 270 whp, and you could prolly do a high-mid 13 if you launch it nicely and get a good 60' also a cold night will help

i dont know about the 93 model a4 but i know that 94 6speed does 220 rwhp stock, so based on that:
-5rwhp (a4 drivetrain loss estimate)
+10rwhp for the muffler
+5rwhp for the high flow cat
+.000000001rwhp for the tb bypass
+4rwhp for the air filter
the tires and stuff dont make horsepower so my guess would be 234.000000001rwhp if you have good low milege.

tb bypass has dyno proven 4 hp before...the flowmaster in no way gave you 10.....

tb bypass doesnt give you anything. at most its 1whp.

ur gonna dyno 240rwhp and ur gonna run 13.9 in the 1/4

i believe a little more than 220, ive saw a stock 6 speed pull 234, and an automatic with 140000 go 225, i dont know if the tb bypass does much, i know the muffler dont give 10. I did a little research and people were gettin a few from the tb bypass, but like 4 or 5. The airfoil was dynoed to actually give 2 hp, and smooth out the hptq curve. I also seen it tested on an ls1 camaro where changing all the drivetrain fluid to royal purple gave 8 1/2 hp, and i saw 10 hp on another car. So i figure aroung 5 for my camaro. My car has 130000 miles

Those are some real dog LT1's to dyno that low stock. Ive seen bone stock a4 lt1's dyno 250 regularly, either that or there is horrible conditions at the dyno such as a potato in the tail pipe!

erickeown

do potatoes not come stock in the tail pipes? guess i better get rid of em

I was going to say a typical LT1 B-car will dyno in the 213rwhp range. LT1 F-bodies dyno more than that.
