Ok well I was asking some questions on another thread but not getting to many responses.

I have a brand new built motor with this (still not in car)

Arias 9.0:1 Pistons
Pauter Rods
ARP Head Studs
ARP Main bolts

It doesnt have cams though.

So my question is what do you think this motor can produce safely?

I want to max out my current turbo safely.
I have been debating on what to do for a while now I have had that motor sit for 4+ months now and I think its about time to do something.

 

Its hard to say, given those specs and that ST system, I would guess somwhere in the neighborhood of 475-500 whp.?.
4 months??, yea, it seems that it is about time to do something with that thing....Hahaha. Let me know if you need any help or ? Good luck with your car.

 

so you think its ok to run it without aftermarket cams

o and I am looking for price qoutes with 2 maps daily and max hp

 

450-480whp turbo is your limiting factor. At around 550whp and up cams are needed. That block is good for 600-650whp....

 

The cams (while the motor is still out) would be a real good idea, if you are considering it. We prefer the JWT S2 cams for the built motors. PM me for any quotes and aditional info. Thanks

 

So you think around 50-480whp with my set up can I hit 500whp with this turbo and this set up or is it not a good idea?

 

Ill do that thanks for your help

 

cams really arent a safety thing. they are to maximize performance

 

Bingo. Cams will net you another 20-40 HP but it doesnt make things any safer. That turbo and motor will get you out to 500 WHP. Especially with cams.

 

ive always felt that especially with ST where all the power is north of 3500 RPM that cams would help with a raised rev limiter quite a bit. I'd be more satisfied with having more power after 5000 RPM which is where you are when the turbo is spooled up. I'd put cams in it if you have the dough.

 

I'm pretty sure that block is close to the specs of Violent Racings 800hp G35. Maybe Mr. A will chime in here.

 

deffently get some new cams in there while its apart

 

Hey whats going on, I myself am running a fully built short block no sleeves and the heads are stock looking to push 550-600 whp on pump safely. on race gas 650whp. The stock tn turbo can flow a max 480-490 range. I had a t-62 and at 18 psi made 485whp so the t60 will flow that range. But now with the T66 i am looking for 550whp @16psi. with no cams the car stops making power at about 6000.

 

I am just going to use what I have and I will do the cams once I get the T66, and the TN methanol kit

Thanks guys for your help

 

No, the above described motor build is more like our 500-600ish whp motors, We sleeve the 700-800 whp blocks along with some other (added) work.

 

I dont think the turbo in the TN kit is good for 500whp without cams, truth is I only know of 1 that was pushed to the max and with stock cams/no headwork it did 460-470whp and over 500ft/lbs. For now Im going with a similar setup-->block, max the turbo but Im doing cams, so I may get closer to 500whp, but I still dont think it will happen. Good luck.

 

I agree to what has been previously stated, so this might overlap some...

With the 60-1 turbo that comes with the kit you're looking at 470-500 at best from what I've seen so far. I think you might be able to break 500 with some aggressive cams. On that motor you're looking at maybe 600whp max with cams, bigger turbo, possibly water/meth injection, and other supporting mods. I'd definitely recommend doing cams before you drop it in as there is really no reason NOT to go with them while the motor is out. With the T66 stage 2 turbo setup, your max goal should be 600whp with cams. Anything more and you'll need to sleeve the block.

I forget what kind of clutch setup you have, but you also need to remember that you're going to need clamping force to hold all that power. JWT will take you to 550whp, RPS 6-puck to 600whp or so, and anything higher will require a twin or triple disc carbon clutch.

Also remember that you're going to need to eventually upgrade your intercooler to maintain efficiency as you really begin making big power (550-600whp). Turbonetics should have a solution if you need to upgrade to a larger intercooler. You'll also eventually need to upgrade to a larger wastegate to support high boost levels as well. This is one reason why I'm holding out to do anything until I have a full upgrade package from Turbonetics.

As you can see, to support big power, you're looking at a much greater cost than just building the motor. There are a few points where there are BIG jumps in cost required to make power safely.

The first is going with a basic FI setup with basic supporting mods and a tune on the stock motor

The second is the 400-450whp mark, which is where you need to build the motor and go with an upgraded clutch. Once you hit 550whp you need to worry about another clutch upgrade as the streetable stage 1 clutches such as the JWT begin to slip.

The third is the 550-650whp mark. This is another huge obstacle where you must worry about sleeving the block, cams, headlift, and going with an expensive carbon clutch setup to hold the power.

Of course, after that it only becomes increasingly difficult to make power, but you're going to have to worry about things like head work, oil coolers, and whatnot. My suggestion is to pick one of those power (or stage) levels that you will be completely satisfied, and build accordingly.

Reliable sources have told me 600-700whp is attainable on stock sleeves and good internals, we'll be seeing it more as we learn to deal with the head lift. Of course over 600whp sleevs wouldnt hurt but they are not necessary-also depends on how long you'll be running those power levels. Obviously a guy running a 500whp street 600whp occasional track set up could run stock sleeves compared to a guy who will be ragging the car at 600whp all the time...

 

That might be true, but I can't recall any reliable sources getting much past 600whp without sleeving the motor. For now, all of the built non-sleeved guys I see around and talk to are under the 600whp mark. I believe you're correct that this will change as more breakthroughs come around for high boost applications. But at this point, I think at any goal past 600whp and you should go with sleeves just for reliability purposes.

My eventual goal will be 600whp (no more) on the stage 2 kit with cams, water/meth injection, and a built (non-sleeved) bottom end on high boost. Normal driving I'll aim for 500whp on medium boost, and lower for cruising long distances. This is a very reasonable goal in my eyes, as long as turbonetics releases the stage 2 kit some day...

 

I agree you should have no problems with that...
