It sure is, nothing has changed. LOL

I don't remember any white Z06 that we did making 630 or 640 RW.

Da Z06

Hummmm.....

I was able to pull 630 on pump but I my combo seems more aggressive that that.

FAST making that power on top lime that? 11.2CR?

What are the intake timing events on that magic stick?

14.5/52.5 :]

Either way the car and customer is happy enjoy the car.....

What was the correction factor for those 630+ HP results?

tekhombre

It's SAE corrected, it's on the dyno graph.

reasonable suspicion

Bad *** build and numbers!

nuke61

Yes, I saw that it's SAE corrected. What I asked about was the specific correction factor for that run. For instance, see the CF for my dyno run that I pasted in the middle of your dyno graph:

I'm not trying to argue but I have been working on and racing ls powered cars since the beginning and Cartek has always had fast cars that produce results. Im not saying anything about this car but in the past they have always backed up what they claim.

RamAir972003

Dyno numbers can be skewd as ****, the ls7 has been out for years all of a sudden people are making 640 on pump gas, nah im not trying to argue either facts are facts this motor to make that power needs more mods than that like I said if they can prove me wrong I will let them build me a motor from scratch This isnt my first rodeo either .....hydraulic roller wouldn't be entertaining anymore to start getting up that high...I mean look at katech for example all these years they have been doing packages not once have I seen there heads and cam package over 570-580 and they have a variety of cams.....all im saying is 640 on pump gas is hard and then your risking of detonation, not all batches of gas are good sometimes....im sure they have by far a great shop and all but that's like coming on here and yea its hard to get a build from Reher and Morrison to get in its months ...and say I made 700 or something from that shop...to be honest when im done with this motor i may hit 610 but again im forged and a 430....

Innovate

11.2 to 1 on 93 octane with an unported fast and stock TB making 640? I am no expert, this seems a tad farfetched. I would like to see trap speed and 1/2 mile results. I am hoping for 600 rwhp out of my setup with a Vararam.

One major thing to consider is that these heads were dimple ported so the intake runner and chamber are dimpled on this setup. That gives a much higher intake flow and higher hp number. Also it's on 0W20 MPT oil.

RamAir972003

In theory; it alters flow by energizing the air boundary layer. Flow bench results show that the difference between a smooth/sanded finished intake port and a smooth textured port is typically less than 1%, which can be argued is negligible.

Basically that's better for carbarated motors, with fuel injected vehicles its a crap shoot.

The only time dimples or texturing matters is where the fuel enters the tract far away from the valve... since most fuel injected vehicles have a relatively short distance between fuel and valve, you won't notice a thing. On older cars with old TBI injectors or carbs that spray poorly, I'm sure there's some recovery of inefficiency, but again this wouldn't be the case with modern injection hardware.

The other side of the equation is the air characteristics, texture changes the way the air hugs and tears from the wall (boundary layer). If you have lots of texture, you also have lots of directions that impede or cancel each other, which is why it will alternately behave like a larger cross section or smaller cross section, depending on density and speed. At best you could see it like a resonator in an exhaust, in most cases it doesn't affect anything, in a few cases it helps, in a few cases it does hurt flow, but ultimately it won't make things perform as well as a bigger pipe.

A vararam dynos 5-10whp less, on average. Either way, you should be over 600.

jayyyw

In for trap speed numbers.

The dimple intake port has been debunked.

My build consists of Ported factory Intake, ported factory throttle body, Kooks 1 7/8 headers and kooks catted midpippes, Varraram CAI, QTP cutouts, and RPM Blower Cam. .650 Lift .230 Duration. Factory Heads milled .010. 550 RWHP 518 RWTQ. and that was thru the cats with the cutouts open. I consider this respectable numbers considering the heads have not been ported and the cam is relatively mild. I would say I could probably gain another 15 with a more aggressive cam and maybe another 25 from porting the heads and decking them another.010 for a total of .020 that would put me at about 590 RWHP. I am not going to dispute the numbers especially considering carteks reputation. But I will say that is one strong engine and hey every now and then you get just that a abnormally strong motor. I Just pulled my heads and sent them to AHP for their stage 4 treatment and street porting hope to get them back next week and hope to pick up another 20-25 RWHP. IF I don't get what I am looking for I might just give these guys a call. By the way I was on 93 oct. fuel
