BoostedRex the suction kit are the Apexi intakes.

As for the rebuild you can always send it back to Apexi but the expenses would be too much though. But anyway here in cyprus we don't have anyone to rebuild any turbo so it's the same for me.

 

A'PEXi AX75F82 turbo kit.

Guys don't get a boner over this kit just yet.

In the Dec. issue of Sport Compact Car Magezine they have the U.S. FD3s version of Youichi Lmamura's Japan drift car. Its a mirror image except the Japan version makes over 500hp for its high speed circuits, the U.S. version makes only 348 at the wheels. Although this hp is nothing to scoff at, listen to how its being accomplished. It is infact using the AX75F82 turbo kit on a 2000 spec Stock port motor. Its ONLY making 348 at the wheels @ 1.2 bar (17.5 psi). Not too impressive. I've seen numbers like this and better with a smaller T04e 57 trim at same boost pressures on stock ports. This turbo is full ball bearing and has the abradable housings, but I think its sized on the small side. SCC also supplied a dyno chart.

Boost comes on very early, the chart starts at 3200 rpm and theres boost already, probly fulll boost.

By 5200 rpm torque peaks at 288 ft. lbs and plateaus till around 5800 rpm then drops 15 ft lbs to 6300 rpm then falls on its face from there to to 7500 rpm were its only 225 ft lbs.

Horse power peaks at 6300 rpm and plateaus for 500 rpm then dies hard after 7000 rpm.

This is just my observation, but this kit seems to be a quick spooling mid range powerd turbo and runs out of puff after 6000 rpm @ 17.5 psi. Not much better at all then stock twins with the wick turned up.

I can see why A'PEXi chose this for them, good response and they don't need a lot of hp for small U.S. drift tracks. Its much more reliable then twins, probly holds less heat in the engine and is MUCH more simpler.

Bet its a killer Auto X turbo.

But for someone with a street car looking for more performance, I really think their gonna be very dissapointed. Like I said, stock twins perform simular if not better, and smaller T04e's perform simular also at a fraction of the cost.

The Japan version of this car makes over 500hp, I'm guessing their using a different turbo.

This is a one dyno chart only observation, but 17.5 psi and 348 at the wheels doesnt impress me. You can clearly see the turbo run out of Puff, and its NOT do to stock ports. Look at T04s, t78, even a T04e turbo dyno charts on stock ports and there torque and hp levels never fall off as hard as this turbo.

Actually, full boost looks to come in around 3800. you can see a slight dip were the wastegate opens then regulates. probly a slow reacting or mal adjusted boost controller

I took a pic of the dyno chart, but its too large to post.

According to specs (inducer size etc.) it should be a kick *** turbo... i dunno whats going on with this one in the mag. I found specs for it, theres also a AX75F92 which is quite a bit larger.http://www.apexi.co.jp/products/turb...01_turbine.htm

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

 

if you go to http://www.apexi-usa.com/ a popup comes up to d/l their price list (which says effective october 2002), they list the price of the kit as $6999. and just because the drift car only made X horsepower, that doesn't mean it's the absolute max the turbo can produce.

 

RacerXtreme7 i don't know which kit you are refering to, but i believe you confused the RX6 with the AX turbine. How is it possible the RX6 wich is much smaller to be able to give up to 400rwhp and the AX75F82 which is the size of a T78 it gives 348 at 1.2bar? Even the RX6 would give more at 1.2bar!!!

 

I somewhat corrected my speculation after I read the specs on the turbo i earlier post. It really should be a kick *** turbo! I dunno what happened to the A'PEXi U.S. spec car. Maybe 1.2 bar is way to low of a pressure ratio for the turbo and its near surge, but I still dont understand the power drop off. Wonder what this sucker looks like at 1.8 bar on a ported motor.

Did you not read my posts?? Tittle says AX75F82. This entire post is about this turbo!!

The A'PEXi D1 U.S. spec car uses this kit accourding to SCC NOT a Rx6, I'm not cunfussing anything, its in plain text in front of me when I wrote this post.

How is it possible that the Rx6 which is smaller to be able to give 400rwhp and the AX75F82 which is the size of a T78 it gives 348 at 1.2 bar? I HAVE NO FREAKIN CLUE!!!!!! THATS WHY I POSTED THIS!!!!!!!!!! I DONT GET IT EITHER!!

Even a RX6 would give more at 1.2bar!!! I KNOW THIS!!! Did you miss my point about stock twins, t04e and T04s making more power at same boost pressures??

Maybe SCC made a mistake about the boost pressures A'PEXi USA is running on this thing? I don't know, I guess I wasent clear in my post that I find it hard to believe the lack of performance thats published on this kit. But like I said in the original post, this is just a ONE DYNO SHEET speculation before I seen specs on the turbo itself. Maybe I'll write SCC to verify.

Also, like I stated before, the Japan version of this car is making over 500 hp, but I have no clue as to which turbo their running.

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

 

Well, i spoke with Apexi Japan before ordering my kit and thay ansewrd that the FD drift car driven by Youichi Imamura makes 500hp at 15psi with the stock 99spec engine.

About the U.S version there must be a mistake or something otherwise they really messed up something on the engine Nope i don't think that Apexi would messed up.

 

Dude, chill out. No need to come on too strong about it.

Maybe you should put this 348 rwhp dyno from SCC. Scan it, not like the last time just quoting it from a magazine.

Good, do that.

There are only 2 versions, AX75F82 and AX75F92 at least for now. The 82 and 92 siginifies the exhaust side, I'd bet that is 82 mm and 92 mm respectively. The inducer side is 64 mm for both turbos. So that's pretty close to a T78. My feeling is that 500 hp is at 1.2 bar on Youichi(sp?) car and you either misread the article or Apexi meant to say it was 348 rwhp before the single turbo conversion. So, scan that article and let us know.

 

no the article does say 348 at 1.2 bar on the single

 

well can someone scan that article for the rest of us or give as a website to find it? Maybe they did a mistake or something. Can someone write to them and figure it out? Or give me an email and i'll do that.

It's just not possible with those number you mentioned even if it was the wrost tuned car.

 

dont have a scanner... sorry.

its not really an article. it has lots of pictures with just little notes... it says "An Apexi super avc-r boost controller keeps the engine at a relatively mild 1.2 bar (17.5 psi) of boost."

but im curious to this as well because i would like a single that has very good response that i can get high boost/hp in lower rpms and still ahve power in high rpms... im more interested in autox but id still like to have power for occaisional straight line.

it is strange for this fd to have the a quarter mile time of mine at 12 psi on nonseq twins...

how are the other AX turbos? anyone know?

 

I finally got my drivers loaded into my new computer, Ills can the article tonight

 

I also found the kit for about $5100

 

where share the knowledge?

 

sorry guys, I cant tell you where I found it or I will be in **** with the forum, I dont want to cross any boundaries. But if u need info or want the copy of the article, email me at bassitup01@hotmail.com

 

i got a quote for $4970 for the AX75F82 and $180 for the instake kit

 

That's hard to believe. That's 100hp MORE than my friend made with a GT3540, stock motor, full open exhaust, and a Twin power ignition.

 

CCarlisi AX7582 is much more efficient than GT3540 and bigger.

 

And somehing i forgot to mention. I don't think that they race on pump petrol.

Most probably they use race petrol.

 

$4970, well ive been doing more research and $4900 is the best ive seen

 

teamafx where from? You have to share it with us.

 

email is the key. lol. Im not getting into trouble

 

any more info on this turbo?
