I didn't pick out most of this stuff myself, but just asked a shop to give me a wish list of the top of the line components for a killer build to go along with my STS twin turbo setup.

undertaker

find a better form of FI than the sts if you're looking to run the number....

And pick different heads. Warhawk LS7X heads have exhaust flow issues

So this is a wish list or a build?

robert miller

He said a wish list.... Be nice shane.....Looks like a nice one which ever it is or becomes. I also agree on the heads better out on the market for the money...

Rich Z

Actually I like the STS setup. Better weight distribution then putting all the hardware under the hood, plus it gets all that heat out of there. Different strokes, fellas, and this is the stroke I wanted with FI. When I look at an underhood turbo setup, it looks like some drunk plumber's nightmare..... Thanks, but NO thanks.

Rich Z

What sort of issues? If you don't mind elaborating a bit...

Rich Z

Actually, I am going to have this built unless I hear of an overriding reason why I shouldn't. It mainly started out being just a yearn to have a 427 engine in my vette, and then got away from me. Sold off much of my gun collection and had some money to spend. Was looking to buy a 2009 Z06 (that 427 thing again), but the dealers were apparently intent on going down with the ship. So I decided to put the money into my 2002 Z06 instead.

ForceFedC5

Intake flows WAYY more than the exhaust. Makes getting the correct cam profile difficult. I wouldnt use those heads.

Have you ever driven in an STS car and a front mount/TTI car?

I'm guessing you havent...

FYI, the TTI x kit is hidden. Not much to see when you open the hood. Almost looks stock except for the intercooler.

You should give Nick/George a call at TTi 253.475.8319

Using that setup with a STS is a waste IMHO. Unless its TOTALLY custom. And if the car is a manual, well..

robert miller

Almost any other set up will blow the doors off of the sts.

Rich Z

Actually, I'm perfectly happy with the STS system, thank you very much. It provides an acceptable balance between the pros and cons of any add-on power adder I considered.

As for the claim about the Warhawk heads:
I have been unable to find anything on the web that supports the negative implications that statement makes. Every head I have looked at flows way more on the intake then on the exhaust. It doesn't take a genius to figure that out just looking at the diameter of the intake and exhaust valves. So apparently this is a completely acceptable design. So if you wouldn't use heads that flow more air in the intake then the exhaust, then just what heads DO you use?

So does anyone have any credible references about this "issue"? Quite frankly, all of my research came up with all positive reviews. Now there were some issues with World Products in the past, but all the later reviews seem to indicate that these were PAST issues.

ForceFedC5

You have a very intesting personality. You ask for opinions but then get upset when people disagree with you?

I'm no engine builder but OBVIOUSLY the intake is going to flow more than the exhaust. The problem is that it flows WAYY more.

Thank you for letting me know that intake valves are larger than exhaust valves

Do some more research. It took me 5 minutes of googling to locate the info.

Or, instead of asking opinions, just do what you want.

PM me when your build is done, if ever, I'll be more than happy to line up next to you

I know that it's your money and you'll do what you want, but with the TTiX kit, there are no drunk plumber issues because you don't even see the plumbing and it's been proven time and time again to put down some BIG power! The weight is in the middle/front of the car and won't throw off the weight bias, where the turbo's in the rear might help with drag racing, but not so much in the twisties! Just my thoughts and could be completely wrong, but I just wanted to put it out there!

If you're comparing a front mount turbo to a plumber, then the STS setup is like a plumber's crack because it's hanging out in the rear of the car like a plumber with some droopy drawers!

As far as the heads go, why don't you talk to some of our vendors here because they have some SICK powerful cars and might have more insight on parts because they deal with them more than most of us do?

Good Luck and either way, it should be BEAST when it's done!

robert miller

David, I can see a race going on here. Be easy on him, he will come around some time down the road, or sell it one.

ForceFedC5

At least its not a 7.5:1 compression 346!

With a 427 it should be "ok", unless he does A LOT of customizing

Rich Z

Ah, kids...... Don't you just love them? And your lining up next to me would prove what exactly? That your peepee is bigger than my peepee?

Nope, I'm not upset at all. You are making claims that as far as I can tell are completely unsupported by credible evidence. I had hoped someone with some credible references would review the specs I listed on my new drivetrain and give me some feedback. Obviously you are unable to supply those credible references via links or you would have done so.

For instance, why would a head flowing WAY more air than the exhaust be a BIG problem like you infer?

Actually that build in the first post of this thread is one recommended to my by a builder, and I am checking up on his choices. So far I haven't heard anything credible to dispute those choices except some nebulous unsupportable claims about air flow differences between intake and exhaust.

And yes, this build WILL be done. Care to wager any REAL money on that?
