Yeah, their Z06 was on the lower end. But they did gain some nice numbers with those mods. I would think that if they did those mods to an 02-04 Z06, the gains would've probably been a little higher.

That is why I am glad that Ken is on the other side of the ocean.I also know that there is always someone faster than you...you just haven't found them yet.

It is sad that John Lingenfelter died before he had a shot at the LS6. Then you could have seen some real rwhp!
Edmond, you are correct!Edmond said:I thought he died around Christmas of 2003? He was alive to have worked on the LS6. In fact, they even advertise LS1 packages on the Lingenfelter website saying that results would be higher on LS6's if the same mods were done, at least that's what they said about the supercharger.
SPANISHVETTS said:LPE offers performance mods for the LS6 and their potential is mind blowing. I guess that I am too much of a romantic…What I meant was that if JL had lived longer he would have personally tweaked the newer SBCs the way he tuned all of the previous SBCs.
Edmond said:Whenever I hear that, I always get a philosophical thought..."If there is always someone faster than you, where does it end?" :L

Cold air induction systems for the ZO6 - I've read, heard and talked to folks that have installed these and yet to see the true dyno results. Everything passed along has been in terms of quarter mile times. Quarter mile times don't determine RWHP. Many other factors also affect quarter mile times. The only true way to determine if a cold air induction system has gained you 10-20% RWHP gains, as claimed, is to dyno it. I haven't seen a shred of evidence that ANY cold air induction system provides a 40-80 RWHP boost on the ZO6 in the 1.5 years I've owned mine.
The mods I'm putting into my ZO6 are significantly more than $3K. But, without any guess work, we're more than likely going to be making 500+ RWHP when it's done. I will have the proof. AND, we are not going into the block, replacing heads or intakes.
Cheers,

Well Said Scat!!!The first production COLD AIR INDUCTION system that I know of with was made by Moony Aircraft Corp. back in the 50s and continues to this day on their non–turbo models. This went from being a hole behind the prop on an M20a to a NASA intake scoop on the 201. The cold air system on the 201 is good for about 1.5 inches of manifold pressure at 200 MPH. I do not think that you will find any after-market system that is as efficient as the one Moony spent 50 years refining. Using this as a benchmark and remembering that the air pressure is going to increase or decrease logarithmically with speed you do not need to be a Nuclear Physicist to sort out how small the gain of a cold air induction system at normal operating speeds is going to be.ScatRat said:Cold air induction systems for the ZO6 - I've read, heard and talked to folks that have installed these and yet to see the true dyno results.

ScatRat said:I absolutely concur. That's why I'm going the supercharger route. Minimum, 180 additional RWHP. We'll see, but that's what we're counting on. Also including bigger injectors, special software programming and chassis dyno tune. Trying to do it right. It ain't cheap.
In response to replacing the LS6 - Good point. The shop I'm working with suggested I stay below 600 RWHP. The LS6 can't handle 600 at the tires and last very long. If you want that kind of power or more, you need to go with a truck block modified for 6-bolt mains and use a forged crank. I believe them based upon what I've seen them do. I wasn't prepared to get that radical...yet.
If anyone's interested, I'll keep you posted.
ScatRat said:As a general rule of thumb, you can expect 45 RWHP loss through the ZO6 drivetrain (transmission, axles, gears, etc). The ZO6 transmission, due to their design and implementation, do cause a higher loss than expected. That said, the horsepower numbers being quoted are all in the ballpark of an expected 360 RWHP car. 345 to 365 RWHP are all close (within 4%).
Dyno runs can and will vary between cars and we all know that. One thing that helps is if the folks doing your dyno runs also provide the corrected RWHP based upon the temp, humidity at sea level for the day you dyno'd your car.
Mine is currently in for mods and it started out in the 330-350 RWHP range depending upon the conditions stated above. We'll see what happens once dyno'd again.
Quick and easy mods for performance on a ZO6? Haven't seen any yet. These cars require serious work for serious horsepower. After over a year of reading, studying and listening, the typical mods that may have helped the LT1s and LS1s don't work for the ZO6. I've heard and read the claims, but no one could provide the proof. If you want horsepower, go with the performance mods that cost $$$ and take time to install. There are no "short cuts" for the ZO6.
IMHO,

Heavy Duty said:I had a friend Dyno his Zzz last week and it turned 350 Horses at the wheels. That is about an 8.5% difference between the crankshaft Vs rear wheels. I thought that there would only be about a 5% difference since these cars have manual trannys. I was at Carlisle last summer and saw a stock Zzz turn 380 horses....which would be about a 5% difference and IMO would be about right. Is there that much difference between each car?
