I received some nice comments but I'm sure there are those who must think this dyno is inflated, not possible, etc...! If so, let's hear what's on your mind. Don't hold back. I won't get offended. Nothing better than a good 'ol discussion to keep things interesting. All comments welcomed, 996t guys, tuners, etc...!

 

Dave, awesome results! I just can't imagine all that power with the stock suspension. Please be careful if you take it to the track

 

Thanks Chris! Straight line is going to be challenging enough.

 

how many miles are on the motor? I have heard of stories of cars with 600whp needing new head gaskets; but then again their cars were not tuned by the engineering wizard Todd Knighton.

 

With those numbers, Dave, think it goes without saying that it/you are nuts Whether the dyno is inflated or not is irrelevant (please refer to my prior d*ck swinging comment). However, did you ever post your baseline numbers?

As far as what's going on with your motor at this point is anyone's guess as you're going into unchartered territory with stock internals. For your sake, I hope that the assumptions of Proto and Switzer (vs. more 'conservative' tuners) are correct in what a GT1 block can take in unmodified form. But as I mentioned to you before, I personally wouldn't risk it. I would get that engine done ASAP.

 

Motor has about 5000 mi
Skeeter is doing the ER911 kit, on stock motor. That's no slouch either. For now, I'm going to try and enjoy it for a while.

 

Thought 1: If you have the money to build a motor, then this is truly a fun experiment.

Thought 2: I'm still curious to see the A/Fs. Maybe ethanol + a killer tune makes for massive amounts of safe power. As far as the gaskets are concerned, you can have aftermarket ones installed with high-torque head bolts put in if you start blowing coolant, no?

EDIT: I guess what I'm getting at is, if you have the money to rebuild short block, don't chicken out. Let's see how long it can hold. You car and $$$ though.

 

I know. I told him the same thing. He doesn't listen to me either

 

I'll see if I can get the numbers from Todd. He doesn't usually release his tuning data. Once I get the car back, I can datalog my lambda's. I think stock head gasket is pretty good (I really have no idea, just saying). Head gaskets can change compression ratio so keep that in mind.

 

It's hopeless with guys like us. We're going to have to learn the hard way.

 

I don't have any baseline numbers with vtgs. They were sold to Asher a few months ago.
PS With A3076 at 16.0-16.5 psi, the car made 685 whp. This thing makes a lot more power at lower boost. Safer for the engine.

 

Hopefully some one can answer with some tested results.

 

Usually if you blow a head gasket then that's probably due a detonation event. Maybe others would know better.

 

Agreed. What would you recommend doing to strengthen motor?

 

For the motor, if you want to keep it 3.6, I would do rods, head studs and some head work...
