H.P and Torque range estimate for converter purchase

I need to purchase a converter for my car but dont have the money to run it on a dyno. Could anybody give me some idea as to where i am at? Any help would be great!
508" Mopar wedge runs on alcohol
Indy little Ez cnc heads 355" on in 245" ex.
871 HH kobelco rotor blower 20 lbs. boost
Bird injection 110 pump
Compression 12.5-1
Camshaft bullet lift 675 in 705 ex dur. 262 in 268 ex. 114 center installedat 110
1.5 rockers
MSD-10
burns step headers
Powerglide trans 1:69 first
4:10 dana 60
Dodge challenger 3300lbs.

 

I dynoed a Chevy with a little more head and cam, 11.5 compression and 17#'s of boost. It made 1550 hp at 6500 rpm's. It made 1220 ft pounds of torque at 4500, peak was 1253 at 6100 and still had 1223 at 6500. This was with a pretty basic fuel system and 30* of timming. You should be in that area with 20# and 12.5 compression.

 

Thanks for your imput, i was thinking that 4000 flash point would be about right.

 

dont know who your thinking of using, but....

This is who does all our cars, and he has years of me and others testing for him, for a blown application, this is your man. Our program has been greatly improved do to Jamie's work. He will have no problem hitting yours right and making you fast.

Give Jamie a call.

 

My combination is similar 481 CI Indy Wedge with .770 lift cam 114 center installed at 108. MSD-12 with a standard helix 8/71 #21 lbs boost 110 pump. The car ran 191 in the quarter with a weight of 1950lbs. You could use the weight and MPH to figure HP if you want. Remember the High helix blowers will make more HP (I was told 100-150) using the same boost becasue they induce less drag on the crankshaft.

Considering my combination I ran several converters and had the best luck with a 4500RPM stall but fought tire shake with Goodyear 17-33 tires. I went down to 3600RPM stall in an effort to resolve the tire shake and increased the fuel flow at launch but I do not think this was the right way to go. Anyway I hope this information helps,

Brandon Booher has the fastest torque converter car that I know of and he uses a Coan converter . Just call Coan with all your info and they will build what you need.

 

We run a 572" Indy headed wedge with a std 8-71 and a 110 pump, its been to 170 mph in the 1/4 and we wiegh 3250lbs on a little 10.5w tire. I would bet your motor would run a little better because of the HH blower. We have more cam and head and you have more compression and a better blower, maybe that would balance out, I dont know.

Our converter stalls at 5500 and with a 4.56 gear its plenty violent, I'm torn between lowering the stall speed or going with a steeper gear. You already have 4.10 gears so it might like more stall depending on your tire maybe.

Im still learning this stuff myself so take that into account.
