Default Cam/headers/bolton guys in here

What should my 01 formula A4 run with mac headers,y pipe, no head work, and all basic boltons? It still has the factory stall and rear end. What kind of MPH?

High 12's to low 13's. MPH should be around 110 to 114.

there are bolt on M6's that trap 118 without any motor work, but they are gutted. A4's can trap 118 also bolt on, but those are extremely light. If he has full all his seats in and etc he isnt trapping 120 unless he has heads/cam

I only trapped 112 bolt on with stall converter in my A4. Many trap 113-114 average bolt on. I trapped 117 with a cam, and I hope to trap 120-121 with heads

Get a good converter, I would have purchased that before a Cam But without the converter I would say mid 12's @ 115. It's really hard to say it depends on so many other things, like weahter, raceweight, and if you can hook.

its a full wieght car will only the rear seats deleted. I have no stall right now,but plan on getting one in the future. You said you trapped 117 with your cam,what do you think you would have trapped without the stall?

not 01Z's car buddie he holds the cam only bolt on record

without the stall I woulda probably just have trapped 114-115.. the converter really doesnt add that much MPH. Just gets you down the 1/4th QUICKER

What's your raceweight? You are either making a ton of power or your car is a shell. You must have a pretty good cam/head combo as well with that trap speed. .

Oops, sorry....forgot to direct that towards 01Z. That's pretty amazing for "stock" heads. How much does the car weigh?
