I agree the combo is the key. It is interesting to see how much power varies from a poor combo to a good combo. At least this gives a range and an average number.

 

im sure you have, but at what compression, his build is for pump gas, any 1/4 mile slips

 

Don't forget that how you get to the displacement matters too. Larger bore flows better all else equal and shorter stroke slows pistons at same rpm and reduces side load on cylinder walls.

 

11.3:1 I believe it was for pump gas... no I don't have slips on it.. HKE does a lot of builds for racers and they don't like to show what they have to be honest.. tipping your hand s never a good thing.. they were TFS 235 or 245 heads.. point being that the combination will decide the outcome. we've seen 670 hp on pump gas at 11.3:1 on one of our 468's so its really not hard to imagine a 408 making 585.. single plane intake I think it had as well... was in a truck I think too....


torlow the stroke vs bore argument/war has been fought and the stroke actually came out ahead by not by enough to say it mattered.. cubic inches is cubic inches.
Erik from HKE will tell you that all day long.. its the combination that makes the power and power is made in the heads.

 

Is that 670 on an engine dyno?

 

No... chassis and it is posted in here somewhere...LOL

 

WELL ON THIS 416 THEY DIDN'T COME CLOSE TO 585 AND IT WAS 13.1
http://forums.corvetteforum.com/c6-p...ferrea-pp.html

 

The car made 560 rwhp, however, that was with a TH350 transmission, 5500 stall, no lockup, steel driveshaft, 12 bolt rear end, 4.10 gear, and 30" slick.


Do you have any idea how much power that combination eats up?
He's lucky to have hit 560. I'd buy that combinatin is a heartbeat. Greg Good heads on an Erik Koenig HKE engine ? !!!
Can't do any better than that.

 

Any idea what this car runs in the 1/4?

 

LOL, no the engine has been reconfigured since that thread.. I have no idea...LOL Dennis posted it... maybe he knows ? That thread is from 2008..

from the thread

 

Yes i do., but comparing that build to this build is like comparing apples to oranges, like you said its all in the combination, that build was 13.1 either way, and the 30 inch slick gave back a lot of that combination compared to the 26 inch tire on the c6, a jump in compression from 11.1 to 13.1 could also gain a very lot, really there is no comparison

 

Well your the one who brought that build into the mix so I'm not sure what your point is...

I stated it's all in the combo.. we've seen 585 from a 408 and 535 from a 427.. its the combination that makes the power.. you that threw engine thread in there and said it was not even close to 585 but also say you realize that the drive-train is eating a lot of the dyno number and then its like comparing apples to oranges..?? I'm confused as to what your trying to say..

 

LOL, posting it on the errornet doesn't make it real or true. Dyno sheets don't mean much to me anyway. I used to work one and when it got out of cal it could read as high as 100 hp off. Let see some video of this combo going down a track. Cartek pretty much has the quickest combos in the country. Et and trap speed is what matters.

 

Not sure what your trying to accomplish with that but have fun with it.. The thread isn't about and neither was my point.. selling an engine or shop to build one. I'm sure Cartek does fine work.. HKE is considered one of the very best... but we're talking about cubic inches and results and money spent vs results.... if you want to get on board with that conversation then great ! But I'm not going to argue/debate who's runs the fastest combo in the country...LOL

 

I agree with your point in general regarding dyno #'s and variances across different dynos, but the same holds true with track times and track mph.

You need context to compare *anything* if the cars were not on the same track, the same day, at the same time.

For comparisons sake it's no more valid to compare someones track times from Houston in August heat and humidity with a car that runs at Atco on a 50 degree 0% humidity day in a November rental when the group brings it's own VHT. They are not comparable.

 

lets compare Houston on a 50 degree day 0% humidity and atco in august heat with 100% humidity , and no we are not allowed to put our own vht down, the track charges extra for each ft of track prep, now if you can see and agree with the different dyno variances across the country, you should see that Houston has its great air days too, and no one is running for a record in august

 

I'm from NJ and I used to live at Atco 2-3 times a week a long time ago. I just grabbed Houston as an example to make a point:

Comparing track times is no more or less valid than comparing dyno #'s. Neither can be done with certainty. It's all just a measuring point that people do their best to standardize to compete across the internet.

The only way you know is to meet up, and run heads up.

....I'm not even bringing up the fact that people don't always tell the truth about their total race weight, putting in race fuel and cranking up timing, and the difference the overall setup and driver make.

Again, I'm not saying it isn't valid and actual racing is the goal many of us had/have when building these machines, but to compare times across the country is educated speculation at best, and no more valid than comparing dyno #'s.

Also there are many people who build their cars to just be a spectacular street car, or weekend hpde car and could care less about abusing their car to get the spectacular low ET we all wish we had.

Different strokes...doesn't make one better than the other.

 

Nice numbers so far man, they should get better too.

 

Oh, well that's a pretty serious factor right there.
I'd imagine that 07 416's numbers could be much higher as well with a single plane or sheet metal intake and huge 105mm throttle body as well.
So far, his combo is using only a (totally streetworthy) FAST 92 with a stock ported 90mm throttle body.





100%

 

True.
Just as one can't compare a car that ran at Houston in December to one that ran at Atco in July.
Remember, the ETs/MPHs on the time slip are the numbers that the car ran, period.
Like Atco (or No Problem Raceway or Milan or MIR or Sacramento), Royal Purple Raceway Park (formerly HRP) is one of the fastest tracks in the nation.

And no, Atco DOES NOT allow racers (rental groups or otherwise) to ever DARE even attempt to lay anything down on that surface other than the rubber from the racer's rear tires.
