fuse discussion

[THATpurpleKUSH 5,000+ posts]

For all those that run small fuses for competitions to get in to as low of a class as possible, what size fuse/s are you running and how long do you have before it blows?

I was messing around with 30a fuses to get down to AS1 or S1 in Meca and it was blowing in about 10-15secs, I was hoping to get more out of it like around 30secs. Now I will have to go up to DB2 for Park and Pound because there's no way I can get a 30a fuse to last 30secs.

I could burp a 30amp on ZX2500. The 30 second run needed a 60

exactly what i do. double fusing for the 30 second round. i run 60 and 120.

Well if I'll have to double it to make it last 30 secs, I can go up to 70a to stay in DB2.

Test it out. The amps eff is going to be the deciding factor. Make sure you try at least three times to make sure it won't blow in the lane

Is there a rule for the type of fuses you can use? Come into the AC world and you can get long delay fuses that would last longer before blowing. You would just need to change the fuse holder.

I don't compete in MECA but iirc there is some sort of restriction about slow blow fuses. @thegreatestpenn could tell you.

Yep no slow blow fuses are allowed in Meca.

so where's the best (cheapest) place to buy fuses from? specifically 30a agu fuses //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I was burping a cresendo 2k on 40a fuses, was getting about 5 seconds, which is plenty. I am now s2 and use 60a on a DD m3 at .5 and I get at least 10 seconds. I had good luck with AGUs last year in AS class. I am doing mini anl's this year. I dont do DB, so Im not sure about that, but 2x sounds like a good place to start

go to a junk yard. you can usually pull hundreds for free.

i need some 70 amp anl's.

ANL's are hard to come by in a junk yard. plenty of MAXI 60A fuses in the buicks and caddys.

does anyone know if you can run more than 2 fuse inline in amateur street? like 2 15a fuses

Can't run maxi fuses in meca anymore

If you're planning on running in AS 1 or S1, you can only run one fuse, in case you didn't know that.

But I would try agu fuses too. Some people have good luck with install bay. But not me.
