It's a Dyno Dynamics dyno. You can not compare it to say a Dyno Jet. It reads a lot lower. Lower than even a Mustang dyno.

The numbers are probably real good.

I have street tires right now, so the track will have to wait a month.

track results are always better,you still have to think that these #s are low

I meant before you added your aftermarket cam.

I read a thread where this particular dyno reads around 50-60rwhp lower than a standard Dyno Jet. So I'll put it on one of those, and take it to the track. I mean, it does feel tons faster, so...... I guess i'll consider these numbers low untill I see otherwise. But I wouldn't feel so bad if im in the 410rwhp range, which is what it seems to be if the DD vs. DJ holds true.

You'll never get close to that with an unlocked converter. You account for say 30 hp for the unlocked converter, and you're right about where that combo should be. And I dont even like dyno dynamics. You can fudge the numbers.
Run it on a dynojet.

Put it on a DynoJet. You should see 390 to 410rwhp UNLOCKED... That cam makes 380s with STOCK heads in A4s all over the country.

Keep us posted. Seems the combo is fine, just a bad choice of dynos.....

take it to the track. tuning is the ONLY reason you put an automatic car on a dyno.

Graph looks terrible...all over the place...I would say lock the converter for more power, and checking timing and the tune overall...you should make quite a bit more than that.

I doubt it is the heads and or cam like others have stated.

Sounds like a customer who is fixated on numbers only. Who gives a rats *** what dyno it is on? Dynos are just tools for tuning in a controlled environment. Every dyno is going to be different man, seriously. It is know that any tuner can fudge the readings to make them display whatever it is you want your car to "make" at the wheels. For instance, we use Mustang Dynos. Everytime we get numbers for someones car they complain...then they run a nasty time at the track and come back smiling...it is all relative to what dyno you're on. True your numbers may be low, but compared to what? Somone else's car and someone else's dyno? Do not compare your ride or combo to anyone else's, that will not get you anywhere.

Take the car to the track and see if your times improve.

Also, dynojets are not eddy current load bearing dynos. They simply spin and give a reading. They do not take into consideration weight of the car or anything like that, which Mustang Dynos do. Numbers are artifically inflated in other words.

Do not let low numbers bother you. Take the car to the track, take note of times and go from there. Check that everything mechanically is running well, and record track times, then go from there.

Good advice ^. I'm sure the track will do great at the track.

2 things...

1. I agree take it to the track...my car with PP stage 2 heads and TR224 cam made like 391/370 but improved over 1.1 seconds after a gain of 80hp.

2. There is no way your car ran 12.2 at 110 stock, does not say is this an F-body or Y-body which might explain it, there are stock C5 Z06's that have trouble with low 12s.

Edit: found it when I was awake Z28 on your top left sig. pick...doh!

ls6 intakes flow only like 260cfm if your heads run true 300+cfm then you may look into buying a ported Fast 90 .

Maybe its a v6 with badges.

my car dynoed at 326 rwhp and 334 rwtq on a mustang dyno, which is a more TRUE wheel horsepower rating because it uses the vehicles weight, on a dynojet i got 342 rwhp and 353 rwtq, because the rollers on a dynojet just spin with the tires and take a reading.

the track is still the true test of wheel horsepower.

What does the vehicle weight have to do with an engines horsepower? Is a 400 hp motor in a 3000 pound car any more powerful than a 400 hp motor in a 4000 pound car?
This is one of the difficulties I've got with those other dynos. The dyno should care less what the weight of the vehicle is. If anything, the parasitic loss of the drivetrain should be calculated.

stock was 13.6 @ 105 maybe.

12.2 was with Longtubes,Stall,Lid,Gears,Slicks/skinnies.
