If i buy this turbo and put some good numbers up will i be bashed as well? NO wait ill dyno it on a dynojet(no correction) then sell the sheets to gt35r owners, and we wonder why no one will take us seriously.....lord i apologize for makin fun of the 35r owners

this **** is getting out of control. What we need is to see two dyno sheets, same car, same boost, and same type of dyno. The **** above where you said its comparable is untrue because you are running one more psi than the 61. Lets quit the ******* people bashing and show some real evidence as to what the turbos can actually do. I am actually thinking of ditching the T78 that i have for the 61 and get that tuned at 17psi to see what it can do once and for all(on my FD). I know johns T2 is running great, and i would like to see some numbers on an FD.

You will never have two turbos dynoed on the same car and even still there are variables.."the AF61R was dynoed last so it was heat soaked"
I'm intrested in this AF61R, while i believe strongly in the GT35Rs that ive seen on piston motors boosting deep into the 20s WITH OUT fail, if this is truely making 400whp+ at 13psi by 3700 rpm for $750 then its obviously the right choice. But the claims being made by the davinci camp don't seem creditable and i have other concerns.
Since this turbo isn't a garret unit, where are the parts coming from and whats the reputation of that company? How will this turbo hold up to constant 18-20psi for roadcourse laping? Or will it even handle 20+ with the mystery parts? Does it outspool the t4 divided GT35r? And where is this dyno sheet with or with out the "20%"
I keep asking these same questions because they never get answered.... Hopefully we get an idea power wise this tuesday after their track day but that still wont say much about responce.

the problem why this is not comparable is that TII engines has smaller runners than the REW engine. usually, when two cars were setup using the same port, turbo, fuel system and ems. You can easily see about 15-20rwhp difference.
Now, if the TII was sporting with the 35R and the FD was with the 61R turbo, I'm sure that everyone would argue that this isn't a fair comparsion. because we all knew that the TII will automatically made less hp than the FD with the identical setup. Not just the turbo selection but the engine efficiency.
If someone wants to see some dyno #'s, I'm sure I can get a turbo from Ron to test. I already prove that the GT40 (4082) wasn't enough for the rotary. I'm sure I can test other turbos out there for comparison. I also have a customer here with the GT40R turbo using our manifold that I'll tune within the next few weeks. I'll have dyno #'s for that as well.

I agree about the dyno part, but boost ovbesouly makes a difference. The whole point of my statement was that we need to see dyno sheets. We will see how the turbo does at the track this tuesday. Like i said from my other post too, i think i might try the new 61 and see how it stacks up. I have a T78 right now at 16 psi, but im looking for a more "streetable" turbo. The T78 while a great turbo, lags much more than these two turbos, and i would like to see how the 61 is on the street. If i were to have a drag only car, like Lupe, then i would stick with the T78, but i street drive mine way more than drag it.
I also thought that the 61 sat on a t4 divided exhaust manifold??? I too would also like to see numbers without the 20% ****, maybe i can end it with my car

FYI, Ron got ahold of a bunch of HKS T51R KAI Turbos from garrett (Very cheap). These are turbos that were left over and are now surplus turbos. Thought you guys might find that interesting.

My guess about this, knowing the schemes you've been involved with in the past, They are the knockoffs from KFG. Keep in mind this is in no way directed torwards Ron. More torwards you. Wasn't it you who ran around telling everyone they had a new turbo kit and it turned out to be a rewelded SSautochrome ebay manifold. I'm tired of responding to you and Khan. You both pull these threads down.

While there is some good information within this thread, there is even more fighting. Like i said earlier we just need to see a dyno on the same type of car, same boost, and without the 20% dyno thing to see how each stack up.

Talk about pulling these threads down..... Look who's chasing down all the AF61R turbo threads.

Here's the bottom line ...
Lupe, or whoever is posting from DaVinci - post ONLY the fact, no "it blow xxx turbo away", or "you're wasting money buying xxx vendors kit". Just the facts. There's enough facts from this kit to hold water without any argumentative statements.
Zero R, or whoeve else is posting from A Spec - quit finding reasons to pick apart other peoples accomplisments. Focus on your own work, and providing information about it.
This **** is totally out of control. Start acting like professionals, like adults. You think anybody is going to listen to you and buy your kit - either of yours - when you're just bickering back and forth like bitches. There are plenty of guys out there that know way more about these topics than you guys, and this pety horseshit is EXACTLY why they don't post here.
DaVinci and A-Spec have both done some great work, accomplished some things that deserve attention from any potential buyer. But if you don't act like professionals, all that is going to be lost, and the only thing people will remember is how silly you sound fighting back and forth.

My 3rd gen will be running a GT35R provided by Chris Green
My 2nd gen will be running a DaVinci AF61R with a 13B-REW
The 3rd gen will be a street car, the 2nd gen will be a road course/track car.
I wrote about the DaVinci turbo setup in RX Tuner, I was seriously impressed. I don't give a **** if some sweatshop in Bangladesh made the parts for the turbo, if it performs and lasts.
This subforum has been pretty much hands off for a long time, but now it's not. All the **** disturbers better take a second before they hit submit reply.

An anti-surge cover will help any compressor achieve a fatter usable map area. The newest research from Holset shows that an even longer anti-surge tube (of about 3"-4" in lenght) will not only fatten the map on the surge area, it will also provide a small increase in ultimate flow capacity by pushing the choke area wide, too. It won't help a turbo spool faster, though, that's a product of a suitable turbine stage matched to the power band expected from the engine, plus the mass of the whole rotating assambly, or more exactly its moment of inertia. An anti-choke cover is mostly to provide usable flow at high boost, low RPMs work loads, exactly what a fast spooling turbo needs. Preventing surge also lets the turbo work easier, as surge is a turbo-destroying fenomena, since it pushes thrust loading on the bearings to extreme, fluctuating levels. Sleeve bearings are most afected by surge, shortening bearing life significantly.
On a related subject, while looking at the catalogs I have in hand, a .313 shaft, as stated by Ron as being used on the AF61R, seems to be a quite thin shaft size. Correct me if I'm wrong, but from what I have read on the Garrett catalogs, T3/T4 shafts spec at .400, while what is know as a "Big Shaft", the TO4S shaft, specs at .460. This came about as I was searching for 360 degree thrust bearings for the .313 shaft size. For such a large turbo, I am starting to suspect the use of such a thin shaft size, a size which I also have never heard of before. Perhaps this is why there is no mention of this turbo being capable of handling high boost pressures, which is also a high thrust bearing loading fenomena. A thin shaft will surelly help speed spool up, though.

Snap out of it ryan, the purple people eater has sank. You need to sell me that thing and focus more on your 3rd gen.

So many numbers for a non-turbo expert to crunch. Can somebody enlighten us over here? Perhaps Ron from DaVinci himself?
