Wondering how much difference there is between the two as far as horsepower and quarter mile times......................
They would be on the same set up, stock heads, full exhaust w long tubes and in an A4 with a SS4000 Yank and with a tune..........................

Also what lsa would be best

Looking for something to make a good amount of power, but still idle in traffic and have ok street manners...................

Car is not daily driven and might see 5000 miles a year

Having a hard time deciding how extreme I want to go and is the Magic 4 that much more horsepower

I will be calling texas speed on Monday to place an order

Thanks in advance!
