I’m in the market for a stronger rear to handle my new motor . I was looking into potential various brands of QC’s that could safely handle the horsepower of the my new motor . I was looking at some of the Winters QCs like the nostalgia and a couple other models but couldn’t find anything relating to what power range each model was meant for . If I don’t go QC another option might be to do a 1957 Ford 9” Motor made 350hp / 360 ft lbs on the engine dyno . I’m new to QC’s so I am not familiar with which models are good for what power range . Just want to try and have an adequate setup , and not go with something that isn’t gonna hold up and meant for lower HP levels.I usually try and go with rears /transmissions that are good for a bit more power than my engine makes , rather be on the safe side to try and keep the car reliable . Car is running 700x16 bias ply tires so I don’t think those tires will hook hard and create a lot of shock on drivetrain like a wider more sticky tire would. Look forward to input from those with experience . Thanks!
We made about 600 hp in our dirt late model and ran a quick change probably wouldn't have lasted ten minutes on the pavement with slicks ,but in the dirt from a rolling start lasted a season and got freshened up with new bearings and seals. Gears looked great after 3 seasons. With those tires you are running that are probably harder than a minister's di**. You should be fine.
If I remember right Beaver told me once they rate their V8 rear at around 500HP and the Champ at around 800. This is just from memory? I've been selling Winters rears for almost 20 years and are yet to have a problem.
Call Speedway Engineering in Sylmar California. Their V8 style QC can handle a lot of street applications and no nothing is common with an old Halibrand.
Definitely no drag strip runs or big sticky tires . This one will only have firestone 700x16s bias plys out back . So that should help not put as much wear and tear as big sticky tires that hook would. This car is more of a cruiser that will see daily driving use .
Winters V8 Quick change with 31 Spline push in axles will handle your situation perfectly and look cool to boot.
I'd have to say that the guys pretty well nailed it., big sticky tires on asphalt with hard off the line launches are hard on any rear end but those rather skinny and hard tires will go up in smoke before they let the QC have health problems. I'm not sure where you are, but I met a Bonneville racer from back east who was running a Diesel V8 powered mini truck a few years ago that had a great looking Franklin QC under it who said he got it cheap because it was some Grand National Team's last year parts. Probably in the right place at the right time and knew someone .
This question always makes me smile. As others have said, with your tires you don't have to worry about a QC being too weak. Even with sticky tires and a clutch you would be fine. Actually, horsepower never really matters. It's all about torque, traction and shock loads. The Winters V8 is plenty strong for what you are doing. You probably want a limited slip differential. Which brakes you want to run will determine the most cost effective unit. If you want or need more strength, then you should think about a Champ size QC. 10" Ring Gear, 12 bolt carrier, several limited slip options and 31 spline floater axles are readily available. Screw the 9" - Power robbing hypoid R&P, heavy ass iron case and axle housings that need 30 lbs of additional bracing. Oh, and can you change the final drive ratio in less than 10 minutes? For 60 bucks? Buy a Winters from an Alliance Vendor.
The Flashpoint car uses a B&J quick change, 866 781 1064. 499 inch hemi on 69% with a 14-71. Has gone 451 out the back end. No trouble yet with the rear end.
You can see them in blown vintage dragsters. If it was safe enough for your nut sack back then you'll be a'ight...
Is the winters nostalgia v8 QC significantly weaker than the regular winters v8 QC? Or is it more of a difference in looks , where nostalgia has banjo looking housings
