guess we'll see how this one goes.

A buddy of mine ran a 15v 280amp iraggi alt back around 03/04 in a honda civic. QUALITY PRODUCT!... he ran his amps at .7ohms (over 3000watts worth in power) and his electrical never dropped below 14v.

I'd recommend him in a heartbeat.

As for the wire under the engine cover... I'd personally loom that just to be safe.

im going to voltrex all my cables once i get some.

how hot does it get under that engine cover?

[The Architect]

just got the stock 80 Amp backup alternator i ordered from lowmileageparts.com

Ill be using this as a comparison the the HO alt i get from iraggi.

I'm eagerly awaiting the result from the iraggi :) Lets hope it works. Im glad you have the balls and the cash to experiment for the greater good :)

A quick question though, what was the original game plan for the DC alt concerning the electronics. If it would have fit, was it going to be a plug n play? thanks

[The Architect]

well 90% of the PnP part was the fitment and it was off so that was a massive fail. Other than that it looked as if the ports and connection were appropriate.

Dom Iraggi has probably the best customer service so far, he's very responsive and reassuring seeing as how I told him my entire DC story along with my concerns and worries about fitment and all the like.

The alt ill be getting will be .5" larger in most directions so as to be able to make 300amp of it but the mounting points will be the same he said.

From the stock casing he could only make an alt to produce around 150-180amps which for a lot of owners would be a massive help but I chose to go all out so Im just hoping itll fit.

Ill be doing a side by side comparison with an OEM alt to see if itll work just by eyeballing and measuring it.

[Slick]

I checked his Ebay page, I didnt see a 300A for the Yaris. He does make it though, its just not listed?? And if you dont mind me asking, how much did you throw down for 300A?

[The Architect]

its probably not listed bc he cant make it "stock" per say bc its not the exact yaris case.

the ones you see on his page are most likely (99%) the ones that he builds from factory OE casings.

the one i ordered that i hope and should fit was 499 then i got the special 1 5/8" billet aluminum pulley for 45 and the shorter serpentine belt for 15

[Slick]

For 300A thats not a bad deal at all. Well, im officially excited :D I hope all works out. Any estimate on how much power will be available? Like, would it support a 10KW system do you think?

[The Architect]

10KW is a litttttle bit rough.

figure the car will use 25amps for typical car stuff so im working with maybe 270 amps

270 Amps x 14 Volts = 3780 usable watts (assuming your yaris sustains 14v typically)

Whats more important is the idling, I should get around 140-150 amps at idle but we'll see. Im the worst skeptic

[Slick]

well then thats just perfect for my two 900 RMS subs :D I cant wait to blow em and then upgrade to nightshades :)

[The Architect]

there goes the rear of your yaris.

[goku87]

and what amp are you planning on using to power your nightshades?

[Slick]

I'm not totally familiar with the capabilities of the NS. They are 1500 RMS a piece. I've read, heard, and seen great things about the AP 30001d. But again idk. If it's too much I'll go to one NS and a ap 1500. Which would make sense bc the 3000 is just 2 strapped 1500

if you're a skeptic... then change your equation.. 270*13 = 3510

when you have a bass hit, it's not uncommon for your voltage to sag 1volt, also... that alt will charge your system quickly... depending on how he makes the voltage regulator, the voltage may drop down quickly to the mid to high 13's.

I just received a whole pricing list from Iraggi:

"Direct bolt on. Same housing as factory.
160 $379
180 $399

Iraggi modded alt. We modify mounting ears to have the same mtg points as factory. Will bolt up almost exactly like factory. This is the one everyone has been doing.

200 $459
220 $479
240 $499
260 $519
280 $539
300 $559"

...Personally, I might look at that 180 Ampere stock housing unit. I am not going to jump for a bigger housing until I see someone that has had success with one that they've purchased. If I see that, I'd probably order the 240 Ampere version for my uses.

With all that being said, Arch...you're going to be posting pictures on the piece and the install correct?

[The Architect]

i wont be doing the install seeing as how I'm not that confident, Id rather let someone certified and so forth have at it.

I will however post pics of the HO alt and the stock alt side by side

[talnlnky]

prices for HO alts is one of the great benefits of going with a high efficiency install with tiny speakers..... less power = exponentially less money spent.

If I had the money... oh yeah... i'd go for the 160amp in an instant... I LOVED my 160amp alt I had made for my mazda (not iraggi)... thing was great for jump starting cars & trucks.

[The Architect]

just got off the phone with iraggi.

the larger case alt should (99%) fit fine and it also looks like doing the alt swap myself will be easy enough although im sure im going to have to devote a day to it.

if you go the 1 5/8" pulley route for higher amps at idle you will probably have to get a special belt for it like I am.

every possible angle has been looked over since I've been scarred by DC power and their absolutely horrible customer service etc etc.

it should ship tomorrow ready to go.
