Disagree. Heatsoak has always been a problem with forced induction. Most track cars are naturally aspirated for that very reason.

 

Then for now we should just use the term- "THE DAMN THING LOSES POWER IF YOU BANG ON IT VERY LONG, SO DON'T EXPECT IT TO GO A FULL SESSION OR BEAT A CURRENT VIPER THAT'S RATED AT LESS HP", but it's not necessarily related to heatsoak.

That should make a new owner feel better.

 

Shut up and take my money Vengence..I am so there as soon as I get my car ,mid to late February ...Think I'll stick with the 627hp tune if it's available because I want to track the car( Z07 S3) and don't want any power oversteer

 

 

2 Inch headers/non catted x pipe and lower pulley on yet?? sorry ron im just getting all parts going for mine. already have 345 drag radials and true forged is making me 18x13s for the rear. I just want to get all the parts here before car gets here since Ill be doing the same thing you are.

 

Was that the same Germans that recently recalled all Porsche GT3s ,not for overheating, but bursting into flames and burning to the ground?.. ...we charge more and our car may kill you but that's fine because ...Ze Germans

 

Okay let's not go there. But just look at the way they handled that whole thing and how customers were treated and compare it the way GM handled the dropped valve issues or other engine related massive blow ups in their top end cars? When your car blows up today, your 100k Z06, they wont even give you a comparable long term loaner, most likely you'll have to get a rental car on your own dime!

 

Outstanding than you will get it while the getting's good! Amazing the difference in power with an FI car relative to the DA.
And maybe 99% haven't ever owned an FI car, and don't know how inefficient it is!

 

They are so much more powerful in the cold simply because you are seeing what you are losing in the heat on top of what a NA would see not losing as much!

 

I saw that Porsche thing too and was blown away. That's why you pay more for the German cars. They are engineered to go beyond what any normal person would ever do. Sorry, but domestic cars are engineered just short of what we expect them to do. They give the huge hp numbers and get everyone into a flag waving frenzy and then...
Well, after a couple of laps the car overheats. Sad.
I wanted to love this Corvette as much as anyone, but the reality is setting in. Great on paper, but...

 

You were talking about german "far superior engineering" and I just wanted to know how "far superior engineering" burst's into flames, the ins and outs of customer service are all over bad ..Like this Porsche owner
The truth is in the long run all the manufacturers come out about the same in terms of quality and the "so called" Heat soak problem is far from a settled issue for the Z06 it's just conjecture for now and if it's not I will be the first to call out Chevy for it

 

Wow, three pages of heat soak concern.....

We are adding a larger diameter lower pulley as I type this and are hoping to see another 2-3 psi gain. It is in the mid 40*s in Georgia this week, but I will go out tomorrow and datalog some back to back pulls to verify IAT1/IAT2 and get back to everyone with our findings. I can say on the dyno the OEM HX system works extremely well, but I have not had much time on the street.

If I may say one thing... PLEASE reserve judgement until you actually drive a new Z06. I have been driving Corvettes for the better part of 20 years and this car is BY FAR the most amazing Corvette GM has ever produced. IF there is an issue with timing being pulled and/or heat soak the aftermarket will be able to address this, but that is NO reason to not own one of these cars.

 

This car is amazing. I agree with Ron, you need to drive one.

 

Exactly. I get the feeling that a lot of the guys posting with "the sky is falling" fears have no experience with the GM aftermarket, and tuners like yourself. For those guys... I'm not calling you out, but just reiterating what Ron is saying here. I also understand there are guys who want a 100% stock car, and plan to keep it that way...and anything short of perfect is unacceptable. Again... let's just take a deep breath.

But I'm in the camp of "nothing stays stock", so I've been living in GM/Ford/Dodge aftermarket world for the past 25 years.

Let's allow the tuners to work on some things like Ron and Vengeance are doing so diligently before tossing the entire thing out.

 

The engineering that GM used was a bit flawed on this to begin with. How many road course cars are ever using PD blowers....I honestly can't think of one example. A PD blower is not nearly as efficient as a CF blower or a Turbo. The M3's turbo's at 20lbs of boost are making incredible heat. If you ran this car on a road course for 30 minutes you would definitely see high motor temps and timing pulled just like the Z06.

I have driven a CF car on the track for years in my own M3. Forced Induction other than very efficient turbo's are rarely ever used on the race track.

If you were going to build a track Z06 a PD blower would not be your first choice it would be a turbo, which is what speculation says is going into the ZR1 C7. I think guys who really want to track their car will need to make modifications to it to successfully get the heat out of the motor as efficiently as possible. Including possibly W/A injection, larger heat exchangers and baffling.

The bottom line is nobody that I know of is professionally road racing a car with a positive displacement supercharger. It is not what you would choose for your first choice.

Given the emissions issues that GM is facing though making a larger displacement NA car is no longer in the cards, FI is here to stay. When GM starts making Turbo'd cars that match up with BMW and Porsche they will then be caught up with the Corvette. For now the C6 LS7 and LT1 are your best options for road racing.

 

It could be a easy as taking ten mins to install a finned heatsink to the blower top cover(or replace with a heatsink top cover) and cost chevy 50bucks to do at any dealer , Which is why I doubt its a REAL problem ...Its too easy to fix

 

i wish these other people would stay on their own thread.

BACK ON TOPIC

so 2-3 psi more so shooting at about 14 to 15 psi on pump 93 gas.

are you going to be doing 2 inch headers and non catted x pipe?

 

We will know boost in about a half hour

Yes, 2" with NON Catted X pipe.

 

And you lost the mods I can do for a California car about seven pages ago! Oh well, guess I'll have to be happy with around a 600 rwhp car, somehow, once I install the air intake and tune.

 

Ron, the issue at hand is that if there is actually a problem, GM should take care of it and not leave it to the Aftermarket. I know you make a living out of this but it also seem that it is fanning the flame on an perceived issue. it would be great if GM issue an statement on this. I can't imagine that they didn't experience this during testing and is going to leave this to the aftermarket and void owner warranty based on this if they use a tune to fix it.
