Just a few questions about putting a turbo on a 347 stroker... I think first question is single or twin turbo's? Im leaning towards a single turbo, less complicated and less parts.. Also in the cobra I dont see a whole lot of free space.. My boss wants it able to make 925HP at the wheels, would run it less than that most of the time just wants to be able to do it for the odd race and dyno sheets..
He also wants to go carb'd... He doesnt like electronics much, I know a fair amount but am no whizz at them either.. He likes carbs, can we do like 1 big dominator carb thats blow through or do a couple BG blow through carbs??
Are headers available that fit the FFR chassis/body for a single turbo or for twins? Or is it something that I would have to fabricate myself?
I'm sure you know this but 925HP will destroy a factory 5.0 block in a heartbeat. You will need a Boss block at a minimum preferably a DART. Single and twin set ups have both been done more than once and if you want a bolt on system call Wayne Pressley at Very Cool Parts and he will be happy to set you up with a tried and true system. As far as installation goes most people use the shorty headers installed facing forward and extend them with a bend pointing upwards that the turbos sit on from there it seems to be personal preference for the rest of the plumbing. Do a search and you will find a lot of good info.

I would recomend building custom headers as they are not that hard and do not cost as much as people think. Twins or single either are fine. We had a stock bottome end mustang that made over 800 to the tires with stock crank rods and pistons but it had a good set of heads and XFI which is a must for a turbo car. Yes you can do a carb but tuning is not near as easy or reliable.
I would recomend building a good bottom end and most of all go to a builder who is good with turbo motors!

Can you say, "Past Tense?"

You are right now it does have a dart 347 which makes more power.
The stock bottom end did live for about 2 years I think and was raced hard ran a 5.80 in the 1/8 @3300 lbs and 275 radials
Here is the link on my engine builders HPJ fourm section from start to end of the car I think last page has the vid.
It is a dart block.. The engine was built to have twin whipple superchargers but they sit about 3" above the windshield and I dont even have an air cleaner on it yet..

I would still go with a fast xfi box or big stuff. Tuning is not hard and many good tuners can even do it over the net with datalog files.

What kind of heads do you have? I have some headers that I bought cheap that did not work for me in my dart. They are made for yates heads
You may want to also look on sites like racingjunk and yellowbullet and find some deals on headers you may think could work then it may be that you only have to change a few tubes if they do not work
Shane, I recommend you go to theturboforums.com (formerly turbomustang.com) to answer pretty much any question you have. At 925 hp to the rear wheels you will need to run race gas only (or E85) on a 347. You should fully hook up the tires on the street at around 120 mph with good drag radials. Have fun.
I will do more reading on that forum Thomas.. I am on there and have been checking it out just havent fount the info im lookin for but im sure more research will get me there. My boss owns an airline and I work at the airport on this stuff so we have access to 100 low lead airplane fuel which we run in most of his toys.. We just ran in the Baja 500 in a jeep TJ with a bored and stroke 4.0L inline 6 that is now 4.6L.. We ran the 100LL in that and it didnt ping at all with 12.5:1 compression and an iron head..
Hopefully these heads will work, my boss bought the engine as a package deal and he doesnt really know much about the parts he buys.. I tried to tell him to go with AFR's as thats what my machine shop recommends also but he doesnt want to do that. If they blow off hopefully it doesnt wreck anything else and I can get the AFR's after all..
You can make crazy power with a carb set-up, but it will not be near as fun to drive or as streetable as an EFI set-up. If you do go carb it will need to be modified for boost and they can get pricey. Keep researching on The Turbo Forums.com you will find all the info you need. You will need just the right turbo and some tall gearing because the car is very lite weight. There are many different kinds and sizes of turbo's so choose wisely. Are you going with 5 speed or automatic? Solid rear axle or independent? Turbo's make lots of torque so you will need big drag radials and a good suspension. Good luck.
Thanks again 2fast, I do keep goin back to turbo forums and reading up when I have time.. We have a built 6 speed t-56 with a ram dual friction clutch setup.. Solid axle in the rear, its a 9" from currie with 3.00:1 gears.. The one thing the boss does understand is its gonna need some big sticky tires.. We are gonna stick the widest tires on the back that we can.. He even mentioned that he has no problem with havine to modify the rear wheel well lip on the body to let the tires hang out a bit too if we need to..
