Just Had the very 1st set of 4.8 Liter Stage II heads installed at ARE. A new design of Wade's. Went 10.76 @ 125.64 with a 1.433 at 3350 lbs 1st time out. See Drag racing section for more details.
For those of you that know the ARE dyno never puts up huge dyno #'s but they run at the track. These #'s however I was very happy with.
HP = 431.7 and Torque was a whopping 468.5 through the mufflers, an A-4 and a strange 12 bolt.
Sure seems funny to run these #'s from other shops you need to make 475 RWHP Real #'s are proven at the track

Uhhhh... 4.8 heads are the same as 5.3 heads. And your torque numbers are squed by your convertor. I hope you don't think that is what it really made. None the less, they are nice numbers and times.

Silvr98z28

MMMM, No they are not exactly.
And as far as the skewed, I have had this convertor dynoed twice prior to this at much lower torque #'s.
Thanks though. I really appreciate all of the know it alls on the board.
BTW I only posted #'s for the "Dyno Queens". I personally don't give a ****. The times speak for themselves.

Could you post the graph?

Can you enlighten us to the exact diferences between the 4.8/5.3 heads. Do you know whats new about these heads? They seem to be working very well. Thanks.

Then if you know the diffrence, why don't you tell us all. Funny how when I ordered 2 diffrent sets of 5.3 heads, they showed up with 4.8 stamped on them. Once again, if you have proof that they are diffrent, show me. As far as your torque, a stock bottom end car will not produce that kinda number, espeacially not that much higher than your HP, unless it is a stroker motor, then your HP is to low. Nobody said anything about being a know it all, I was just stating the obvious. I gave you props on your nice HP and track times, if you want to be an ***, then

were these locked or unlocked numbers? nice number, and damn what a ET MPH that is, I do beleive that number one heads and cam NA ET isnt it?

Silvr98z28

Beast96z, thanks for the props. Not trying to be a dick, just posting the #'s from the pulls which I was standing there for. As I said accurate or not these heads are running strong. No tricks were being performed.
The difference from a 5.3 is the chamber. I'll let Wade or Dave post up to tell you about them. If not, give them a call.
There is also more in it. I'd be happy to line up with Brent (Cartech's car) same weight same track
Yes #'s were locked.

Hey I have the FIRST ARE 5.3L heads

My numbers are decent too (See Sig)

hehe

There is no difference in a 4.8 vs. a 5.3 head.From the factory they are all the same.

Yes the heads are the same, even chamber sizes. We are very pleased with the results! 10.7 H/C car is flying at close to 3400lbs. We do however install new bigger seats and valves (2.055/1.57). Re-shape and open up the cumbustion chamber. Also new one-piece bronze guides are installed.

Thanks for clearing up guys. Remember I'm no mechanic, just like going fast.

So, you're saying your car made 468RWTQ with the convertor LOCKED on a stock bottom 346"? Sure!

Silvr98z28

Peak torque happens way before locking the converter genius.

The 475 rwhp numbers you talk about are an M6 car. You undoubtedly know that M6 cars out-dyno similarly modded A4 cars. You have to compare your times to other A4 times, if you're going to use dyno numbers as a measuring stick. Many a 320 rwhp A4 cars have smoked 400 rwhp M6 cars, it has nothing to do with the dyno numbers, it has everything to do with the fact that an A4 has a HUGE advantage at the track, both in the first 60 ft and down the 1/4 due to its favorable gearing, IMO.


TSP ran 10.78@124 @ 3400+ lbs with about the same dyno numbers, and others in the 420+ rwhp range have also run 10s (A4). To "run" these numbers, you don't need 475 rwhp in an A4 car, your times are right there where they should be, congrats.

Rich, Stiring the pot again

Silvr98z28

That's my job, that's what I do.

that abnormaly high TQ number is the result of Torque Multiplication from the converter....My STOCK motor made 450rwtq on MTI's dyno....it's a 4000 Vig....but when u flash the converter on the dyno you "Trick" the dyno w/the torque multiplication....you have to get to 3rd gear and use a Tech 2 and lock the converter then nail it.....then u will get the TRUE Torque numbers..

JF WS6

Exactly...... but apparently Silver98Z knows it all, so you don't need to tell him that.

Silvr98z28

Go back and read and you'll see that I stated that I really don't give a **** what the #'s are as long as they have improved. But ARE must be doing something right. I didn't make the heads, I just had the ability to pay for them. If your running the same or similar combo why don't you tell us all what you run.
Keep your #'s to yourself though because I really don't give a ****.
