Thread: How Much HP Can a B13/B14 LSD Tranny Hold?

No, lol. At 24psi i made 461whp, and 391wtq, I know at 30psi after the new intake manifold power was over 500whp and im sure tq jumped up with it, being it would absolutely destroy the tires worse right as it hit peak torque. So id assume 425-450wtq easy. lol

lol, no wonder why honda trannies last soo long, cuz they have no torque

Exactly.

Ben I hear what you are saying with reving higher to fall out of peak TQ between shifts, but above 300-350 ft lbs B13/14 boxes are hit or miss. You can have the best driving habits but it only takes one bad flex of the stack to send it to hell.

I installed a 99 P11 box to drive the car around for a few weeks while I rebuilt a 2000 P11 box. Lets just say it never made it past week #2. At that power level it destroyed 3rd gear rolling into boost hard maybe a handfull of times.

Ben theres a huge diff bewteen 300whp and 400whp. The diffrence becomes even larger when u talk about 500whp.

Stratton.

I would. Absolutely. I'd make 250 peak wheel torque from 5,000 to 10,500 rpm and keep the transmission (and weak, streetable, transmission-friendly clutch) alive.
500 WHP.
Done.

Assuming a certain amount of peak torque from a certain amount of peak power is something I'm not willing to do.

I disagree. But whatever floats your boat.

Ben what is it that ur building ? A b16 or was it a d series....

Stratton.

Now I have to hear how you will accomplish 500whp with 250ft lbs of peak tq... On a SR20 and not a B16. Please explain this.

Given a range of simular displacement and turbos used why can't figures for HP/Tq be assumed?

The p11 came from a friend in bel air Md.

GT3076R or similar turbo. ARP rod bolts. Stiff valve springs. Solid lifters. Stock or extremely mild cam. Maybe lighter pistons/rods if you're feeling fancy. Rev to 10.5k. Progressive boost control. Done. (A SR20VE would make it much easier, but not required.)

Because given identical displacement, identical turbo, and very similar HP numbers I've seen a torque range spread of 60 WTQ or so. Which to me is a big difference.
