T61 vs. AF61, decisions decisions
 
Hey guys,

Heres the situation, im currently running the Ebay turbo, on street ported motor. .60 , 1.15a/r supposedly. I really want the AF61, ive wanted it for awhile. and i was planning on buying Dhahlens since he has aquired a big ole T51r, and he was nice enough to offer to sell it to me for a reasonable price.

Heres the thing, one of my good friends with a PT67 single turbo supra said he has a new T61 sitting in his garage that he will sell to me for $250 (since he loves my car and wants to see it haul ass). Its got a .68 a/r on it, but he said i could probably just use my 1.15 (in a way thats good since i dont have to modify my downpipe to slap it on).

So heres the thing, it would take me next week to pay for the T61. But it would take me about a month+ to pay for the AF61. Since i have alot of expenses.

Now what do you guys think about the performance of either one. close to same? etc. etc. on the T61 will i make over 400whp at 14psi and maybe closer to 450+ on 18psi??

I bet the AF61 spools up alot faster. The turbo i have on there now even with the 1.15 a/r i hit 10 psi at about 4000. kinda late yes but its nice staying out of boost when u want to. As far as track use is concerend its not a big deal to me as of now, since thats what i have an FC for.

Should i just pick up the T61. try it out and if i dont like it and get the AF61 if dhahlen still has it or davinci has more instock. OR, should i just drop the idea and still go for the AF61. although it may break my piggy bank.

BoostedRex 03-09-06 03:24 PM

Break the piggy bank. The spool up of the AF61 and the fact that it will hit the same power numbers if not better ones at identical boost levels should be enough to convince you or that.

PhatManBUD 03-09-06 04:15 PM

We'll see...i mean for $250 tho. hard to beat haha, another $400 is my business license plus more...but ill sleep on it and we'll see what dhahlen thinks

z-beater 03-09-06 05:12 PM

If you do not pick up the AF61 I am sure that there will be another person that will. Especially if Dhalen hits the 500+ numbers at 22psi.

fdracer 03-09-06 05:16 PM

the af61 is gonna spool slower and make more top end. it's just a regular deisel turbo. if you need just the turbo, you should just buy a new one. there's no point in getting a used one when a new one is so cost effective and you save the headache from any problems that might come with a used turbo.

My vote goes to the T61, and if you don't buy it, let me know if I can for $250 :D

Zero R 03-09-06 08:00 PM

I say T61 for $250 it is hard to beat that performance, for that price, on a new turbo.

If you had a clue about this subject you would know that about 90% of all automotive based hi-performance units are derived from "DIESEL TURBOS". .....please enlighten us otherwise.

Also, the T61 WILL NOT spool quicker than the AF61 unless it has a small, and restrictive .84 or smaller turbine which, will suffer major hp loss after around 6000 rpm. If you decide to buy the af61 i'll honor the rest of the years warrenty that i offered when sold..

Either way, as ZeroR said the t61's price is crazy cheap for a really decent performer, just be sure it carries some type warrenty or you just might be stuck with a shitty, filthy, and smelly paperweight!

AF1 03-10-06 08:26 AM

I aready bought the used AF61R. Best luck to you if u pick the Af61R.

PhatManBUD 03-10-06 09:08 AM

you guys think ill be making similar hp numbers +/- 15?

im hopeing to be at least 400 at 14psi and over 450 at 18.

RacerXtreme7 03-10-06 09:49 AM

My vote, T61. But get a 1.00 or .84 turbine for it ("restrictive above 6000 rpm" :rolleyes: not quite). Your downpipe will still work provided you get the same v-band or bolt attachment that you have now (In otherwords, your turbine disscharge will be in the same position).

~Mike...........

PhatManBUD 03-10-06 10:41 AM

ill look for a 1.00 a/r now, but for now i think ill just swap out everythign else.

how about posting a few numbers using the .84 vs. the 1.0 at say 16 psi.. you will atleast 20-30 hp @ 7500 rpm low mr. know it :rolleyes:

RacerXtreme7 03-10-06 11:19 AM

Your one for posting number aren't ya :lol:

PhatManBUD 03-10-06 11:24 AM

Maybe ill try posting number with the 1.15, and the 1.00.

If my maps were tuned for the AF61 with a similar setup, do you think it would be safe to run those maps on 14psi with the T61 til i get it street or dyno tuned. They should flow close to the same amount of air right?

ummm, i never said that most turbos weren't based on deisel turbos. dude, you're just reiterating what i said. the af61 has a larger turbine housing due to it being a deisel turbo, so it does spool slower than an automotive turbo, but it's got a ton of top end. btw, i do have a clue since i sell hundreds of these turbos every year.

..and you'll be tossed in the idiot pile too! damn it...it's getting full quick!

BoostedRex 03-10-06 01:07 PM

Guys, can we keep this from become another flame fest in the single turbo forum? He asked a question and people are giving their opinions. It doesn't need to turn into another us vs. them flame thread.

GUITARJUNKIE28 03-10-06 01:13 PM

i'd go with the t61. you can find a compressor map for it, and it's not built with "mystery" parts, so you can have any turbo shop service it, should it take a dive. the turbine trim will also be easy to get info on, if you ever decide to swap the hot side to something smaller or larger.

LUPE 03-10-06 01:25 PM

Does the T61 come with a 2 year warranty like the AF61 does?

Parts for the AF61R are very very very easy to find.

willjs7 03-10-06 01:55 PM

try and buy the af61r, i know i did, for 2 weeks, got nothing but bullshit, no returned emails, no returned PM's. no phone calls, i called 2-3 times a day. have fun trying to get an af61r. :)..

The AF61R's are on backorder again. Dhalen is selling his AF61R, though.

They've been super busy lately but things are going to change soon (For the better).

Dude chill.

Aren't you a business owner or at least represent a business? Isn't this a place were a LOT of your customer basis derives from (this forum)? Nice behavior, but it seems typical from you and those idiots who seem to be constantly licking your ass.

I had a long reply typed up as to your "posting bogus numbers" and in general straight up lies (anyone remember a certain someone saying the AF61 was a "special turbo" that GARRETT modifies? :lol:). You are the king of it bullshit, but to keep this thread civil and on topic I'll refrain from posting the complete bullshit you have posted in the past (good thing for your sake a lot of those post got deleted, but there’s plenty of readers here who won't forget it). So if you have anything else to say to me be it another insult or whatever (though I haven’t a thing to say to you), PM me and keep this thread from turning into garbage.

I’m sure the temptation will be too great for you NOT to post an ego induced idiotic reply, so I'll let you have the last word and wont respond to it on this thread as to not ruin PhatManBuds post.

sure they are. only problem is you don't know what the hell is in there, so you don't know what to buy.

Ding wrong again....i had a long convo with ron yesterday and the day before he told me why everyone gets the wrong idea about this turbo....and i now get it why everyone wants to call this an s300......there is some work that goes into this turbo....its not "off the shelf" and if i wanted to rebuild it myself i could since ron told me what parts i would need....but since IT DOES HAVE a 2 year warranty why do it myself when Ron's a no BS guy and wouldn't hesitate to help me out.

It's already been stated that it's a modified S300. We're you the one who said that there is no way the AF61R is modified at all? Weren't you the one who said 400whp was impossible to reach with the S300?

of course he's gonna tell you that so he charge what he charges for the turbo. how do you think he can offer the warranty, that doesn't come from the manufacturer. he makes a healthy enough profit from the sale of the turbo, that he can afford to fix it for free. just ask who manufactures the turbo there are only a handful of turbo manufacturers in the world, he's not building them himself. that's not to say s300 isn't a great turbo, it makes a ton of power, it's reliable, and it's the best value you can get for the money.

if you're gonna that it's modified then spit out what exactly is modified about it. tell us what's been done to it that makes it so special. the average consumer can't exactly go buy an s300 and modify it himself, so what's the point of keeping the "modifications" a secret. and if it's so specialy modified why are the dimensions and a/r's exaclty the same as an off the shelf s300. what's the point of lying to people who are giving d-r their hard earned money. it's still the best value out there so people will still buy it, and the shop still makes a good profit on them. both parties win, so what's the point of all the bs.

fdracer 03-10-06 04:24 PM

i know they've been posted, that's why i know they're the same as the s300's.

z-beater 03-10-06 04:32 PM

BUD- I can't speak specifically on the T61. But there is an awesome database that has compiled a bunch of turbos with dyno graphs. I can't find the site but you might want to look there.

Ultimatley when choosing my turbo I looked at the most hp that I would ever want. It was 500. So granted for the price the AF61 was the best bang for my buck. Look at the max hp that you want and then size accordingly. Spool and all the other small attributes will fall in line after you choose.

From what people are asying the T61 sounds like a good turbo.

Anyone have a link?

PhatManBUD 03-10-06 04:49 PM

i see what u mean, im looking for 475-500 whp max when im completely ready. but right now something that will give me over 400 at 14psi. just enough to scare the shit out of everyone that goes for a ride

I'd love to see this too. I have a very very hard time believing that this old turbo design effiency (claimed 82%) rivals Garrett's new GT series (common efficiencies are high 70% with only like 2 or 3 compressors getting to 80%), and IHI were theres hover in the upper 70's also.

No prob, the T61 is a great match for ported rotaries. Theres several people who run it (I think one guy's ID is TransAm something or something like that runs one). And it has Garrett reliability and cheap and available parts.

btw, I have yet to knock the AF61, just the way it was untruthfully marketed at first (thats putting it politley, more like flat out lies about the turbo). FWIW, it is a good bang for the buck, its just too bad it was shrouded in BS when released.

NYT also sports a T61 on his Rx7:
https://www.rx7club.com/showthread.p...&highlight=T61

I deleted his PM, however I believe he said around 450hp (or was it 475hp?) @ 20PSI.

Bi-State Auto 03-10-06 06:15 PM

Lets put it to rest! check with people whom have used both units and make your own choice...and not give in to the preverbial "sheepish"comments.

Anyway, who in the hell are you to critique the af61 when you have only 1 fucking idiotic jackass saying its a straight s300.. thats like saying because your vehicle has 4 tires its a car! i have not sold 1 unit that hadn't met it's expectations!

..... you notice how the negatice speaking morons keep feeding from others ignorance just because it's declairative!

man, this board if is full of blind haters! :fawk: :fawk: :fawk:

PhatManBUD 03-10-06 06:20 PM

i orginally wanted the AF61, my friend has one its awesome. but due to budget reasons im gonna be going with the T61. Maybe when it takes a dump, or its not putting out like i want it, ill move onto the AF61!
