and what you did to achieve the greatest gain.

I'm trying to get more torque and I'd like to see what others have achieved and what has sent them backwards?

Thanks in advance

 

FYI: basically, hp is calculated by multiplying the measured torque at a particular RPM by the rpm. Since the rpm is plotted linearly, a constant torque would give a linearly rising hp curve. What actually happens is the torque rises to a more or less constant level at the lower rpms (around 3000) and stays relatively constant, until engine breathing punks out, then it starts to decrease. as soon as torque starts falling at the same rate as the rpm rises, your hp has peaked out. What you really need is a graph of torque vs rpm.
as an example, Road and track once did a test of a San Francisco cable car. torque went from zero to it's max value max in 1 second, as the cable was gripped. a very flat torque curve with minimal rise.

the typical mini will show about 75% max torque around 2500, max out around 4000, and slightly drop off until 5500-6000, then start to drop more severly after 6800. best my rig ever did was 174 ft-lbs at 4500; 160 at 3000, 130 at 2500.

 

2500 - 150 ft. lbs.

3000 - 160

3500 - 174

4000 - 177

4500 - 177

5000 - 177

5500 - 172

6000 - 158

6500 - 149

 

Are these numbers corrected for drive train loss?

 

Most likely not. I am curious if driveline loss for torque is the same as for hp. Any ideas?

 

I believe the 23% reduction will rule the torque war. More boost at lower rpm eguals more HP and Torque. I have put about 10,000 and about 10 runs down the 8th on the car since the install and everything works fine.

 

Spillman,

Very impressive.

What have you established as your effective redline?

 

Help me out here.

I see 200 ish for hp and 185 for torque....where does 23% come in?

 

My apologizes for not being specific but the 23% I was refering to was the supercharger pulley reduction amount. 19% supercharger pulley and a 4% crank pulley.

 

My redline shifts are at about 6750-6800. I know this is over taxing the supecharger a little bit but the car keeps pulling hard up until then.

 

You may be right short of turbo and laughing gas.

Hey, like, here's mine, eh?



Oh, wait, you said 'torque' - Jeez, I'm sorry, eh, I thought you said 'toque'. . .I'm such the hoser, eh?

 

my numbers were recorded by Hubie and are wheel readings, not "corrected"

 

Not even close

 

Really, can you elaborate?

 

Thanks....your contributions to my education are always appreciated.
