I got my Ravez fix for the day and it is a good one. Wow, entertaining to me, costly to you. This one will be a beast once it is built. I cant wait to see the dyno. Yes, we are learning and unfortunately at your cost. I feel for you...Jeff

 

did you calculate to see if the 14psi's pulley size is safe enough for the impeller speed of the turbines? what is ATI's limit?


sounds like a plan Bill

 

ATI's site says the C-2 will run up to 30 psi.

 

ravaz, I'm glad your satisfied with the plan you guys worked out. How satisfied you are is what matters and not what we think. I'm curious to know how much additional money your looking at with parts for all the upgrades. I know the labor might be a special deal but just curious about parts although I know that you haven't decided on a clutch yet.

 

wow wow! ravaz i cannot wait to see that setup on the Z! Thats about what I am runing on my eclipse and about 14 psi so far. At 14 psi this little dodge motor doubled its hp, and its only a 2 litre motor. 14 on a 3.5 is going to be fun! and that ati sc pushes a lot more air, i cannot wait to see the dyno on that thing!

 

Labor is heavily discounted, and parts are all at cost. It should be a fun project, and hopefully nothing will blow up this time.

 

again, it all depends on the owner and how they maintain their cars


what experiences have you had w/ domestics.

 

My experiences of domestics vs imports were as stated. I did not maintian either one differently. What i did notice was that American products tended to break more often and that the manufacture tended not to modify their product due to known problems where as Japenese products that had a problem, they problems were fixed and changed in manufacturing.

Again, this has been my experience and I can give you very specific examples of both.

In Addition, I had more unsatisfactory experiences with domestic dealers. Ford, GM, and Dodge products tended to not fix anything under warranty even if it was 20 miles out of warranty where as Japanese products i have own tended to fix things even when they were a little out of warranty.

 

Um... lumping all American cars in one pile is like saying "Japanese cars" or "European cars".

Most performance-oriented American cars are V-8s. A V-8 has to work a lot less to get horsepower and torque than a 6 or 4 cylinder. Heck my '76 Cougar went way past 100K and it was a piece of crap. But the V-8 in that sucker was unkillable. I even heat-locked it once when I ran out of radiator coolant. I thought for sure I had just welded my pistons to the block. Came back an hour later, and it started up like nothing had ever happened.

Now American four-bangers, there are some really mediocre engines...

 

You have had different experinces than myself. I have won 4 and 6 cyc domestic only, no V-8's

 

This is the statement that I'm concerned about. The amount of boost that a turbo or blower can make depends on the size of the engine it is connected to (amongst other things). You should verify with ATI that the C2 blower can safely and efficiently generate 30 psi on the VQ35DE engine running 9.5:1 compression. Or if you only plan to run 14 psi, then all the better. But you should still verify with ATI that the C2 can manage it safely and efficiently on your motor with it's custom modifications.

The bigger the engine gets, the harder a specific blower (or turbo) has to work to make the same boost. A blower that maxes out at 30 psi on a 3.5 liter engine cannot efficiently make 30 psi on a 5 liter engine. You'll have to get a larger blower to handle that 5 liter engine. You could keep the smaller blower, but you'd have to run less boost with it.

But anyway, I'm not saying ATI is lying. Not at all. I just think it'd be a good idea to verify with them that the C2 blower at 14 psi will be efficient on your particular setup.

If not, it'll just be blowing a lot of hot air.

 

I remember ATI posting on a different thread that the blower is way under its limits on the Z, and that it has a lot more RPMs left in it on the standard pulley.

 

What specific examples have you given me

I sure haven't found it in this post. There are good and bad dealers w/ all cars, there are good and bad problems w/ all cars. You still haven't given me specifics.

I don't know what you are talking about when you say they fix problems mid production and such. What problems are you referring to?

I've had the warranty issue you mention go both ways for me.

 

why was this directed at me

 

I'm pretty sure my tuner has contacted ATI about this and I'm pretty sure they said there would be no issues with this, but who knows, I don't know of anyone that's done internal modifications including lowering the compression and running the Procharger on the Z's engine. All I know is they agreed to hook us up with the smaller pulley, so I'm thinking all will be good, I guess we'll see. I'm just dying to see how this all works out for my car, I really hope it works out for the best, I seriously won't be rebuilding this again if anything goes wrong. All I know is I want my car back before the track closes down, and I want to drive this thing soon!

Bill

 

didn't top secret build a VQ35 and put it in a r34 skyline, they were getting about 800whp, Im sure about that.

 

I'll take 800 whp

 

Very true on a lot of the statements you made.

The blower might have a maximum boost rating of 30psi but in a lot of causes you cannot get that much psi out of it. You may need to look into the maximum impeller RPM of the blower and how much airflow your engine has.

In a lot of cases you will reach the maximum RPM rating on the blower before you reach the maximum PSI rating. If you go over the maximum RPM speed on the blower you will over spin it, causing harm to the head unit.

I have found out that in a lot of cases ATI blowers can reach 14psi easily. But to be safe you may need to contact ATI so they can calculate the speed of the impeller on the C2 blower on your engine.

looks like it run lean
was it only one bad piston, how dose the others look
