Is 575whp possible n/a?
Vararam B2 - standard air bridge- 90 tb - Fast 90.
Current setup has no MAF.
I have said this many times. It's not 2002 anymore where that was a decent number. Now you have bolt on ls6's making that or maybe even a bit more on a dynojet.
I completely think a 346 can make 575 whp. It may take a better intake than a fast tho......or different runners in the fast. They have talked about making those but I'm not sure if they ever did. There is always the msd but i have not seen much info on their cathedral intake.

Looks like alot of testing went into that, it would be nice to fit that on a 4th gen, I bet its possible. They have a good writeup about it on there website dont they?

1) One being that people settle for off the shelf aftermarket parts and don't challenge themselves or their performance shops enough or simply don't want to spend the $ or time it takes. A lot is in the details which takes time, and that time cost exta $,especially if you are not doing the work yourself.
2) Others are satisfied with the average hp and that's enough for their needs.

3) And likely all of the most savvy successful racers don't even discuss their setups let alone post about them.
Look I don't doubt you know your **** and I've seen plenty of what you posted. But given the fact that in the past 20 years this has not been done before and posted, you can see how I'd be skeptical. Hope you get there, but I'm not holding my breath.
So once again, you're saying that in nearly 2 decades you're one of the first, if not the first, to actually want to push the envelope and not settle? All these vendors, builders, enthusiasts etc. (probably thousands if not tens of thousands of builds) for the past 2 decades have been ok with mediocre results even though the platform can surely handle much more? I somehow doubt that.
Of course most serious people will not even bother to post results and their secrets, but you'd think that if it was that easy to get 500rwhp then any ol' joe with more money than sense would go up to a vendor and say "gimme 500rwhp" and then post it for all his buddies to see. If it was this easy, every vendor on Earth would advertise "cam only, 500rwhp, come get it" to make lots and lots of money. Somehow I doubt people would not want cheap 500rwhp and vendors would not want to make money off people by doing a simple cam and then boom 500rwhp.

I never build any of my setups for dyno numbers. But it's hard to deny the power it makes based on track performance. That led me to thinking about what a 346 could make especially since I haven't raced in a while and have now taken up bench racing.lol
And I hate seeing people settling, too. Too many 430 hp H/C/I cars. In 2016 that's unacceptable if you're wanting a hot rod. OK if you don't and just want some more power.
Damn......i missed that thread. Can anyone hook a brotha up with a link? I've been debating on turning mine harder and using various online shift point calculators that seem plausible. But i would like to have more substantial data before i go there. You and discussed that once when you did your bolt on ls6 a good while ago.

At the World Cup event I was short shifting the car at 7100rpms since I felt I had the other car covered. I would have spun it to ~ 7600rpms I felt I needed to win but that I always plan before the car ever breaks the staging beam. I try and keep everything calculated knowing the risk vs. reward. A few times I did hit the limiter right around the traps, a risk I was willing to take. Be smart out there.
When is that rental?

In the last few different setups I've build it was still climbing at 7200rpms, albeit not by a much.
That's why I must shift high for best ET.
You need to have a stable valve train to avoid the car falling on its face and then you can take advantage of the rpm on the strip with a modified car. Figure out the rpm band the car will be in on the drag strip based on data logs. Know exactly the shift recovery is. If your car is setup well and carries the power most likely you will need to be shifting over 7K. That's why you must build the car to handle that kind of rpm of you care about max performance.

Almost always you need to be shifting well over peak HP.
For example:
The c6Z bolt on, street car setup that we put in the 9's several times was shifted over 7k and I think the power peaked under 6500rpms.
If you want to maximize potential on the strip.
I'd start by figuring out the max you are willing to shift your ls motor and run through the traps at. Make sure the valvetrain and motor can handle it.
Then spec a cam that will likely perform well in that rpm band.
Calculate your PUC and that will give you a great starting point.
There are plenty of supporting mods on the market to support the power and rpm and the FAST is one of them.
The mistakes I see happen a lot with these ls motors is:
- people trying to use torque curves to establish shift points
- shifting at max HP and not understanding PUC
- short shifting the car because the car is not setup to handle the rpm it needs to maximize the cam
- shifting in the correct rpm zone but the car is not setup maintain the higher rpms
...all of which results in less than ideal performance.

I bet most LS performance shop owners will tell you that there is so much more potential that can be had from their setups but they need to make packages that will appeal to the masses for success of their business.
And most probably find it hard to justify charging their customer for all the time and labor it would take to make huge numbers. And frankly most consumers aren't will to spend the $. I see this stuff all the time.
That's why often you see some of the fastest rides are shop cars because no one is paying for all that time it takes to get things optimal.
I'll close by saying to go and listen in on some Prostock threads. It may take 50 pages of reading to pickup one tidbit of knowledge. Most don't post anything and that doesn't mean those big hp cars aren't out there.

No, I don't think that's even necessary. Check out that thread on CF.
