Hey Guys

Anyone know the amps of a TL-P alternator at idle around 800 RPMs? And correct me if I'm wrong both the TL-s and TL-p have a 120 amp alternator? So are the amps constant or are they less at idle?

Thanks

 

only 105 for TL-P

TL-S has a heavy duty amp

 

Im not saying you are wrong, but why the hell would the type s have a "heavy duty" alternator? Not like it comes with anything that needs anymore current than the TL-P.

 

the review says so "heavy duty"

the TL-S has 4 channel ABS instead of 3 channel, a VSA system vs TCS

torque sensitive steering vs speed sensitive

these may make a difference, therefore having a 120amp is reasonable

 

How bout my question, anybody?

 

I would assume that the alternator is the same, the rating is different because the redline is different. So the output at idle would not be as high as at redline (105/120 are listed as 'max'). You could check the part numbers for TL-P and TL-S alternators and find out that part at least..

 

ummm it should be close to the same. because when I have the car in idle the alternator keeps up with everything - when I look at my voltage on my capacitor.

 

Hmmmm....ok cool, I'm trying to decide on a HO Alternator and the one I'm looking at is 180A but produces 80A at idle.

 

why? I mean how much power do you plan on needing? I have over 1100 watts RMS, and with the capacitor it never drops below 13 volts.

 

Since 80 max at idle is almost as high as the TL-P max, I think it's safe to say 80 is higher . If it scales the same the stock would be like 50 max at idle..

 

where did you get the 80 max at idle info??? And what the hell are you talking about?

 

 

hmmm I see...well that is my fault for not reading more closely!
but, I still say the stock alternator is plenty for most big systems.

 

The thing is some Alternators are made to kick on at a certain RPM and stay at max throughout the RPM spectrum. Since the TL-P is 105A I woundering if it stays around that at idle or is considerably less like most Alternators.

 

I'll have about 2000 watts so a HO Alternator is definitely something I need.

 

I don't know, testing it would be a pain without the right equipment. But if it is always generating 105A and only uses say 40A for the car (stereo off)..I guess that extra 65A would have to be dissipated in heat? That's a lot of heat.. too bad calling a dealer is unreliable for solid answers on anything. Call Japan .
