I was just looking at C4 transmissions and what I've found so far is they're rated to 650hp. I was looking at 950hp-1000plus. What transmission would be able to handle this? My future plan is a 331 forged dart block, very large turbo, and N20 with all the bells and whistles to go along with it.

C4 w/ transbrake is what you want fron here....

Dynamic Racing Transmissions

Here's another option : Performance Automatic

I appreciate the links. I may be wrong, but I always though transbrakes we're for automatics. My mustang is a 5-speed. Does that make a difference is transmission selection, or if I still would use a transbrake? Just in case you thought mine was Auto..

well based on the title of your thread

The C4 is automatic......

You are correct transbrake are for automatics....

the thought of your tranny never occurred because it appeared you were looking for a something that support big horsepower.....

so i recommended the dynamic transmission.....

so to clear this up clear this what do want a manual trans or auto that will support 650+

I never knew C4 trans were for auto's only. I've just read a lot of you guys have them and are very happy with them, with the big hp your making. It sounded like a tough trans thats durable and can handle a strong motor with the added stress racing puts on it.

I've never considered switching to auto. Is that something to consider when the power of the motor reaches a certain point? Or do manual trans hold up as well as auto trans and it just comes down to personal preferance? I would prefer to keep the car manual even though just pushing down on one pedal sounds nice.

You can have you T5 built up pretty nice to support quite a bit of power, Reggie is running a built T5 on his car and he's putting down 530 horsepower to the wheels. Additionally on the C4 it's tough as nails when built right but just so you know, it's a 3 speed automatic meaning no overdrive, meaning higher rpm's on the highway.

Would a 6 speed be better for the application then if I still want to be able to drive it on the road? I'm looking to restore and modify everything to show quality. I'd like to take it to a track for autocross occasionally, but drag it once in awhile at the strip for some fun. I know with the track suspension I might lose a little on 1/4 mile times because the suspension won't be strictly for launching, but I figure with the HP it will be fast enough for the kick in the pants good times. Mainly it would be driven around town during the summer with the top down. I just need to figure out what to do about a roll bar that still looks good when the top is down. And what transmission could handle my future plans. I'm already pushing 3000rpm on the freeway. My cousin was telling me today 6 speed might be the way to go. Any thoughts?

going back to your original post....

what is you determining factor for that much horsepower....

before you start picking out transmissions you really need to come up with a definite on the engine combo

Just for the record a 1000 Horsepower car is not a beach/blvd cruiser

BS...its a crusier, a cruiser that makes frequent stops at gas stations..my grocery getter is a 427 side-oiler thrunderbolt.

and while were on the topic of C4's...what company is it that made the "cigarette box" shift kit? all it consisted of was 2 springs for the acumulator and what-not...that kit alone made the stock C4 evil..so a built C4 with a shift kit can handle some serious HP

i like a smart ass....thats an ass that can pay the bills on time and remember to bring home the dry cleaning.


but you werent talking about that kind of smart ass???

seriously tho, thats my dream (grocery getter)car. and i would drive a car like that on a daily basis. can you imagine driving out of the parking garage after work in a car like that??? there wouldnt be a car alarm there that wasnt screaming.

i drove my mom's B/f's red boss 428 drag car to a walmart..then stopped by a mc-D's drive thru on the way home. i love it. you know you have some power when you have to turn the car off to place an order, and then again to speak to the drive-thru window attendant

Feel free to correct me if I'm wrong, but with a 331, forged internals, the top end parts I have now, unless I need to ugrade them to accomidate the turbo, n2o, or new demand on the motor, and 100-150 shot of nitrous, with a turbo like the one listed below, I figured I could be in the ballpark of 950-1000plus hp. And why is it such a joke to drive a car like this around town. There are plenty of cars pushing that kind of hp that are street legal. Granted most are suped up exotics, but the 2010 hennessey viper is pushing 1200. No I don't plan on driving it 459 miles to LA, but aound town to shows, an hour and a half to the track, or just to cruise, why not?

The Viper has a 510 cu in. motor to begin with along with the fact that it produces 505 hp to begin with so it's really just a matter of turbocharging it. Not that it's not possible but it'll be on the ragged edge of a street vehicle with small displacement and you have to ask yourself whats the point of having all that power, the only thing that you're going to get for all your troubles putting it down on the street is a telephone pole, not to mention that you're going to need a serious block, along with a serious fuel system, a big cam, cage and the big turbo which the lag is going to be horrible on such a combo which all in all takes away from the streetability. 1000 hp sounds great and all but it's just not too realistic for a car that gets driven a lot there are a lot of "little" things that add up that end up turning it into a high maintenance vehicle.

[RLG34750]

I have over 500rwhp and this is a n2o car and it a handful on the street.....

from you are saying you want pro 5.0 horsepower and cruise the blvd

it can be done but its not practical as said earlier the much power will required major chassic stiffening....(full cage)

at the least a 9" rear with that power i say major transmission ugrade most race application tranny are not designed for "normal" driving....

cooling will be another area of concern......

and last but certainly not least the price of a 1000 hp

put it this way.....is more the double of what have in your car now including the price of the car.....

But as i always say you money .....your car

My suggestion for this project is planning

Good Luck.....
