It is not a streetable combo for me but streetability is in the eyes of the driver.

What size cam are you running and what is your gearing? I have a 4400 stall right now with SLP LT's and an ORY with an open cutout at all times. I'm still running the stock 2.73 gears. It's fun and a little rough right now but I think once I get the 4.10s in it will tighten up the converter a bit. That should make it alright. Depending on your size cam you could go smaller with stall (unless it's a monster). If it's a big mf'ing cam then you obviously have the same idea about drivability as I do and could probably handle 4800. Try and get ahold of SUX2BU, I believe he is running a huge *** stall w/ a TH400 and a 12 bolt with 4.10s as his DD (not positive but I think that's his setup).

What are the goals for your car?

I imagine you do not need a stall that big at all bro. Most people who run 4400-5100 and up stalls are running cams in the 24x-25x duration and are wanting a straight up drag setup or a wicked street setup. If you plan on doing a cam swap with a larger duration cam like the TRex that stall might be okay. I still think it would be overkill for any other cam. The X3 and MS3 guys are doing 3800, 4000 and a few 4400 stalls. My Trex (242/248) starts at 3500-4000 rpms. A 4800 stall would start right in the middle of it.

Your 224 cam has a powerband of around 1500-6500 rpms or so I would bet. A 4800 stall would put you at the end of it pretty quickly. You could go with a 3500-3800 stall and see some great numbers with that cam and hold on to your streetability.

I see in your sig you are running a lot of nitrous as well. With a 4800 stall and a lot of nitrous it will probably flash to around 5500 or so off the line. This will kill your first gear with nothing but wheel spin. Nice for show, bad for racing. You will spin through first gear and bog out in 2nd. I don't run nitrous but I hear a lot of nitrous guys talking about staying in the 3300-3800 stall area.

I would do some more research and talk to guys through PMs who are running the 224 cam with a stall, running nitrous with a stall, and running a stall in the 4400+ size before going that route. This will give you a lot of info to base your decision off of. Good luck bro!

there are plenty of guys with stock heads/cam guys running 4400-5100 converters. yes they are generally all out drag cars, but SUX2BU ran a 5,100 with his stock H/C set up and drove it daily.

i think that converter would work great with that cam as a maximum effort t.c. driveability is up to whatever you can deal with.

I thought he was just going for the SI record? He also had stripped his car of anything that weighed anything (including airbags, bumper supports, wiring, etc etc). I think he even swiss cheesed parts of the frame and even swiss-cheesed a lightweight Kirkey seat and runs a 31in tire. That's a pretty extreme overall setup-not for the faint of heart. I believe he is running a TRex with his setup now. Look out fastest cam only record holders...

Where does the car make peak tq and hp?

When I got the coan converter for my car, they never asked about my cam. They asked for peak numbers and where they are, how much the car weighed and what the rear gear was and they got me the right one the first time. Streetability is all up to you, it'll use more gas, but a big stall on a street car is awesome!

weight right now is around 3400 lbs -me (no ac, no front swaybar, no power steering , no catback, no heatercore n assbembly, no bumper supports, no spare or jack, lighter battery,lcas, and some other little gutting) cam makes power frum 2800-6800 so i though it would be a good stall speed for the powerband. Everyone always says they wish they went bigger stall than they did? Just not sure what it will flash to on spray 120.

Call up Coan and tell them what you are doing, what power you make, and that you plan to spray on it and see what they recommend. I'm not familiar enough with Coan converters to say it won't be able to handle the spray, but from what I've seen/heard with other converters, the torque will make it flash up through 5k no problem.

broken98

thanx will do

If you spray you do not want such high stall. Spray raises your stall dramatically and your shift extentions.
I use a VIG 3200 on juice and it used to stall close to 4K with juice and extentions never lower than 53>5400

i ran around a 4500 stall and then when i went up in power in would stall around 5200. and i could drive it around and i loved it. i was so confused at its streetability, power braking it would barely go above 3200, but i could drive the car aound and stay under 2500. i didnt think it was an issue at all. just ease into it out of lights and itll move the car with out going all high in the rpm range. personally i think youll be fine but then again i drove a 9 sec(at 7k + da) powergilde car on the street lol

Too high of a stall for that cam IMO.

As mentioned before, call a TC manufacture of your choice. They will want to know where you make peak TQ at, peak HP, weight, gears, are you using N2O? (have a dyno sheet handy). I woudn't use the the how big of a stall to see how big is streetable analogy cause your going to get a million opinions and possibly get the wrong stall, talk to the pro's. My .02

No.

Also, the best-sized stall you can get for your car is one that is around 300 rpm less than your peak torque.

my 8" race converter flashes 5K in high gear. i run the **** out of it on the street on the weekends.
depends on what you can put up with.
