Road Racing Carbureted?
 
I recently purchased another FB that I plan to slowly make into a race car. At first I was thinking of swapping in a TII engine, but It seems like for less work, I can get similar power from running a decent carb setup, even with a 12A (still want to go 13B though)

Is racing with a carbed engine practical for a budget, or am I looking into something that will be more trouble than it's work. The only experience I really have with carbed cars was am SA I owned for a while, and my only problem with it was that it would sometimes cut off while corning on downhill turns.

Just wondering if I'm looking at the right choice. I want to try to make between 250 and 300 hp if possible, but I'd be pretty happy with anything over 200. Not sure if it's really something possible with a track car, or something more suited for drag cars, or if it will work correctly long enough for me to participate in a track day and come out without any worries or replacing or repairing things.

Thanks.

The only issue I see is your hp goals.

Carbed setup can be reliable but make sure you have jet extensions so you don't go lean.

Pick a class you want to run in first. Read the rules so you don't spend money on something that won't fit within a rule set.

+1 pick a class first. i put a PP 12A into an ex-pro7 car which puts me right into TTB/PTB in nasa, so its up against, stuff thats WAY faster (potentially).

2. holleys are mounted sideways on a rotary, so they don't like turns. weber or EFI

3. you hp number basically puts you into peripheral port territory. see #1

+1 to above, you're treading down a path many have trodden down before, only to run into the wall of 'I have no where to run this car', especially when you're on a limited budget. You're going to find the classes where you could possibly make your car (as described) work are going to be super expensive, and your car will have limited potential compared to the competition.

Thanks for all the info guys. So it's looking like I may be better off going Turbo on the 7. I need to look more into the different classes. Right now I'm thinking track days until I can get all my safety stuff done and up to par. Not trying to go out with other cars in an FB. Not exactly safe cars as I'm sure everyone knows lol.

I'm really just starting to get into racing (well, trying to start racing that is) and I'm still a bit clueless on some of the things. I'm comfortable going fast, but I'm still really slow on braking and getting back on the gas, things like that, that don't really matter on a road, but could make all the difference on a track. Also no so sure how comfortable I'm going to be on a track with other cars, but I'm going to try to start hitting the go kart places around here. They hold actual events that use their karts. Seems like decent budget racing while I'm getting my car put together.

You should consider autocross. It's a great way to get your feet wet, and you can start with what you are currently driving...

I plan on auto crossing, but I work Sundays right now, and our local races are always on Sunday. Also, last one for the season was last Sunday sadly, So I've got a few months before I can get out there.
