It depends if you want to dyno race, or track race.
There's a large number of individuals who post dyno numbers, but for one reason or another can never make it to the track. More excuses than you can believe.
I've personally put down over 535rwhp on the dyno... and detuned the car because it's faster on the track. Well maybe not last time :D
If they won't take their car to the track and put it up against other cars on the track, who cares what the dyno shows. It's a well known fact that A4's don't translate power on the dyno as well as the MN6, but that doesn't mean squat when it comes to the big end and who finishes first. I've seen some phenominal cars on the dyno who can't hook it up at the track. So who's faster?
It's a very dynamic balance between horsepower, torque, grip and track condition (not to exclude weather and other factors we can't control)
Nearly any of the top tuners can put horsepower under the hood... The question should be, who can get it to the ground. Dyno racing is one thing, bring it to the track and put it down where it matters.
The other point I would add to this thread is that none of the alleged big "dyno" cam and heads cars that get to the track seem to get the big mile per hour figures that would be consistent with the power claimed. For example, shouldn't a car putting out 425rwhp have a higher mph than 118-120 regardless of the driver? This fact and the fact/coincidence that a huge number of the cars with the big dyno numbers come from Texas does make us non-Texans wonder. I am not saying that the heads and cam cars are not putting this power out, just that it would be nice to see some high mph at the track as real-world evidence of the power. Also, it would be nice to hear a bit about the drivability of these cars--idle quality, level, amount of lope, etc.
I'll throw our name into the hat. #'s are in my Sig. I have trapped 123.76 MPH N/A. The car is DAILY drivable in Houston traffic & summer heat, perfect idle with A/C blowing & CD playing. AND, I've averaged 25.9 MPG on a trip from HOUSTON to TULSA & back. As far as dependability, I have been driving the car in it's current state of tune for over a year with NO reliabilty issues at all.
The best part is that at WOT, she's got a Battle Cry from Hell. :cool:
Brent(Z500HP) has the same pkg on his & drives his around town regularly with no probs.
Darth: 124mph is a good trap speed. However, how many other h/c cars do you see getting the same?
You must have a good amount of lope to your idle. For example, when you have heat in the motor and are at a stop signal for 3 minutes or so. It just must be the case. I have some lope in the idle of my 427 and it has a 229 cam with a LSA of 114. I also understand that the larger displacement is supposed to mellow out the cam as well. What cam are you running?
Seeing LG's numbers and CARTEK's Z06 post recently leads me to believe that it's a moving target. I've got nearly 400 rwhp on mine (A4) and I'm damn happy.
The location of the person should have no relationship to the results of the Dyno. The software used by the dyno and the methods employed by the tuners are more important. If the brand of dyno, installation, ie. in ground or above are the same, and then the correction factor and other software components are appropriate, you should get reliable results. there are some games people can play to get higher numbers but assuming this is not the case, you can't argue with the output numbers. The simple fact is that you can tie the MPH to HP to some degree, but not entirely because the driver component is critical. Also, HP is meaningless in the hands of a bad driver or poor suspension setup. I believe that any good tuner can get 425-435 from an LS6 or LS1 with similar mods. that is, heads, headers, cam, intake, air box, computer tuning, pulleys, etc. It should be noted that not all tuners do their own flow bench work. Many have to send their heads to someone else to work.
But who really cares about dyno numbers anyway? At the end of the day, lets go race and see who gets the most out of a H/C setup. Forget about you guys with spray, they should not be considered acceptable competition in a heads up HC duel. forget about the SC/Turbo crowd if they are making big boost, they are in a different league. Lets put all the BS to bed. Lets have a challenge amongst all the true heads, cam, headers, and other minor mods based members. We would have to decide about tires. Should ET Streets and drag radials count??? But let's say, whoever has the best pair of runs over this coming season is the champ. No money, just bragging rights. Just for fun and to put this kind of meaningless rhetoric to bed and put one of the real reasons for power to the test. Go fast. Go quick. What do you guys say? Any comments, ideas?
If you check my sig, the best numbers at Hallsville were with @425rwhp courtesy of nitrous. The H/C package goes on next week, so we'll see what the NA numbers are when I get back from CA.

Re: HEADS / CAM (rfgoss1)
Mako,
the way a dyno run is conducted is very important, and can affect the putput numbers. There is one dyno in Dallas that backs the car in, to get fresh/cold air in the intake, and the temp probe is near the exhaust, hence it is near the heat. The numbers are big, but they are witnessed by many. Then they go to the track and do not run the numbers, then they add NOS.
I would be willing to have a head and cam car run normally aspirated in a head up race, if you can put one together. I think I can get one of my customers to sign up for this class in a Corvette Shootout. There is one scheduled for(I think) Sept 29th.

I would love to compete.
