What car a lot of new models have stretch belts and I don’t know if U can get a smaller fit for a smaller pulley. It's a little 110hp Nissan versa. I think he did a self exciting mod. I'm gonna text him now to see. Link to comment Share on other sites More sharing options...
Dragonsyph Posted February 1, 2019 Report Share Posted February 1, 2019 What are the effects of to tight if a belt? ♦ Sundown NSV4 18" + Sundown SALT-4 Baby ♦ MechMan Elite 370a + XS3100 - XP3000 ♦ SHCA 1/0 OFC(blue) + SMD Fuse Holders(blue) ♦ Pioneer AVH-2440NEX + SHCA Pro RCA Link to comment Share on other sites More sharing options...
reedal Posted February 1, 2019 Report Share Posted February 1, 2019 Too much tension could cause it to break prematurely. I have a 91-3/4 inch belt on my 03 tahoe, and that length with my Singer 270 pulley leaves me with about an inch of movement on the belt tensioner.

He's been running his stock alt since then too lol. He even placed a couple firsts in Fontana last weekend. Dude is clamping around 6500 on stock and 7400 on his built alternators. Hit a 154.8 on a stock 110 amp. I have that alt a month tops. Link to comment Share on other sites More sharing options...
k58.cross Posted February 4, 2019 Report Share Posted February 4, 2019 Fuck a HO alt, just load up on batt power, watch your voltage then use a charger between demos/drives? Link to comment Share on other sites More sharing options...
SnowDrifter Posted February 4, 2019 Report Share Posted February 4, 2019 What are your alternator temperatures? You might need to look into some sort of cooling solution for it. The thing's going to be working fairly hard. 240a on 9k is doable if you're not looking for constant play time, but heat will be you enemy here. A cool alternator is a happy alternator ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

A cool alternator is a happy alternator I doubt he's put a temperature gun on it. he's getting his belt situation worked out and putting the 240 back on which is now a 300 amp by the way, they fixed it. I'm learning a lot about all of this. Makes me confident my Mechman 270 amp in my Maxima will get the job done with A LOT of lithium. It's nice having buddies with big builds to learn from. I'll let him know we should check running temperature asap. Thank you Link to comment Share on other sites More sharing options...

Alternators have an internal fan. The faster they spin the more air it pulls through. Don't keep the thing under load at low RPM. Rev it up to 2500-3k and let 'er breathe ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Shouldn't be hard to Fab something up. Link to comment Share on other sites More sharing options...
