squeezing out horsepower.. cheap? So i'm at 334 right now and I'd like to be at 350 before I throw a cam in there. I'm putting on a 25% underdrive this week and also a smooth bellow. I know thats not quite enough to get me there so I was wondering if there is anything else I could do??

smooth bellows wont really free up anything at all..money is better invested elsewhere, and i doubt a UDP will give you 16 RWHP either, how free is your exhaust system and do you have to deal with emissions?

open cut-out gets me 8hp going around a magnaflow cat back.
udp it does seem to rev faster but iI have heard the numbers are not
real high. The best seat of the pants mod you could do at this point
would be a stall.

with an auto don't worry too much about dyno numbers. your track times are what you should shoot at. Once you go with a lower gear and stall your dyno numbers will be hurt compared to an M6, but the track will tell the true story.

i plan on stalling and camming and doing everything, was just trying to finish up all the bolt ons, I know at this point numbers don't matter compared to track times, but still wanted to squeeze as much as I could before doing the bigger items. My exhaust is fully open and no emissions are left on the car. I have a cutout sitting at home but I may just sell it to go true duals. I also went with an ebay bellow. 30 bucks, gotta be better than nothing

mjs. I'm going for it all. strong car on the track and high numbers. I do understand once I stall it that my numbers will go down. but I plan on doing heads/cam and possibly stroking if I don't go 6.0
and yeah it was on a Mustang.. I'm not overly concerned with numbers, just wanted to see if there was anything else I could do before I start with the big stuff and 350 was just a nice even number

In my opinion, once you have the heads/cam and a stall, that 15rwhp or so that you're trying to get right now will really not matter much. I wouldn't worry about getting to that 350 number whatsoever, especially with an A4. I would be concerned with making sure that the car is running the way it should be with the current mods you have and that it's properly prepared for the extra power that it will likely be seeing from a H/C swap.
