Tell me what yall think? I know I stink but possitive input would be great. TIA I need help with making this thing a little faster at the track. I don't give 2 ***** about street racing anymore, I am hooked on the track now.

 

Let's hear it AP1-destroyers. I can't chime in because I launch at 4500 in an AP2 with no clutch delay and slightly spin the tires off the line. I think I netted a 2.1 the first time, running 14.2 @ 97. When I got the 60ft down to 1.9 and timed the shifts right, I made it 13.89 @99.

What you need to do is take your car to an HDPE/road course event. You'll be hooked on that for much longer than the 1/4

What do you mean clutch delay? And there aren't many road courses around my area. I would love to try it. It looks like a lot of fun and looks like I would love it, but like I said I just moved and don't know where I can find these types of events. but thanks anyways.

 

AP1's don't have to worry about that. The AP2's has that delay to help smoke the clutch I don't see what else it's there for. My diff fluid looks fine after about 4k without the delay.

 

6k rpm... feather the clutch out...

 

Same as slide im startin at 4500, slight spinage of the tires then my S is gone!
Like everyone is saying it takes practice and you have to have confidence in what you are doing its all mental man.

is that an electrical delay? hydraulic?

 

Hydraulic 1-way bottleneck valve.

 

interesting. so just remove the valve huh.

 

Harder than it sounds. It took me about 2 hours to do mine. The easier route is to just purchase an AP1 cylinder, swap, and bleed. I can do that in about half an hour.

 

slave or master?

 

Slave sir. The masters are the same.

 

ok, good to know if anyone was to do an ap2 tranny swap...

 

Regarding that.. I don't think a tranny swap (AP2 tranny on an F20) would be as effective as a final gear swap, not to mention its more expensive.

 

yeah, but, expense may not be an issue in some cases.

i like the fact tho that gears 5 and 6 are actually taller while 1-4 are short.

and no messing with speedo gear right?

 

Actually if you look at specific ratios in the manual, 1-4 is the same, and 5th and 6th is longer, but the secondary reduction ratio in the tranny is 1.2:1 vs 1:1(ap1). This gives you the impression you described, that 5/6 is the same while 1-4 got shorter.

I haven't seen an actually tranny swap up close, so I couldn't tell you. I've done a full AP2 motor/tranny swap, and that didn't require messing with the speedo gear.

 

Interesting note.. if you use an AP2 tranny with an AP1 rear end, your 5/6 gear will be longer than any other combination. 4k rpms will give you about 80-82mph vs 75.

Yea, I figured it would be good for at least a couple MPGs. And we didn't "bogart" ****. We filled it up with useful information.

What is the AP2's clutch delay for, again?

I thought it was to save the synchros.

 

Nah man, it's there to smoke my clutch. It's not good for anything else.
