Default Anybody run a manual trans with BIG power???

I am contemplating on possibly switching my T400 for a T56 or TKO trans. I have 1000 hp and 800 ftlb of torque but I only run low profile 17" tires. The car does a 1.6 60' and weighs 3600 lbs without driver.

Reason I am thinking about this is for the extra gears for top speed and driveability on the road track and standing mile challanges I would like to do next year.

Any experience? I am trying to find out from those with similar setups what there pro's and con's are.

Thanks for any info.

Talking Jerico!!

Jerico makes a 5 speed road race transmission that has had 1300 horsepower run through it. The article explains everything. Check this out...

That thing costs as much as my whole car. I have a pretty tight budget. I have a few people who would trade me a t56 setup for my trans. One guy will trade me a t56 setup for my converter!!

I think T56's can handle more power than they are rated at but I still believe that if you have good traction your 1000 horespower would destroy a stock t56. I have one and love it, but I only have around 400 horse. Here are some links for t56 stuff. You should be all right with a t56 that is modified for the power. You might want to consider a gear vendors under/over with your th400, or a 4l80e and paddle shift.

If you can get that T56 to handle the 1000 HP reliably then that would be the budget way to go, but the Jerico isn't going to break. You have an awesome ride by the sounds of it. I woulld save my pennies to be sure the trans isn't going to explode on launches.

A T-56 is the best bet,I have D&D built T56 in my 94 Z/28 and has taken alot of abuse with no problem,it has everything done to it.I have a stock viper T-56 in my 69 vette with no problems.

A T-56 is the inexpensive way to go,I know some guys who run 9's on stock T-56's.


A for the TKO 600 I had one and wasn't happy with it,sold it to a friend who had to have the thing rebuilt to work right,this was a brand unit.

The biggest key to lots of power throu a manual is the clutch.

I also love my T56 (done by Rockland Standard www.rsgear.com)

However...

If I was you at 1,000 hp (I'm only at 700), I'd go Richmond 6-speed.

I've driven the Richmond 6 and it's much more civilized than the Jerico.

I might also look into a Jeffco, but the Richmond is a killer piece that can handle that level of power and still shift like a 'real' transmission.

Aerodynamics are the issue with super high speeds. That is why I said leave it alone. All options said so far are fine and dandy but safety and aerodynamics should be addressed first, IMO.
