A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam First, if you don't want to see LOW numbers, stop reading here. 
357rwhp 370rwt were the final results
. I can't say I was too surprised since as you can see with my previous mods, my car dyno'd low to begin with. When stock, it was in the 270's. Maybe my car is an LT1 disguised as an LS1 . In my earlier post a few months ago, I predicted 350-360, so I was right on. Here is a list of stuff done during the install...
TEA 1.5 5.3L heads (about 10.8 compression)
Hammer Cam on a 114
LS6 Intake
RMS Ported Throttle Body
RMS Tuning
Yella Terra Rockers
Upgraded Timing Chain
Comp Hardened Pushrods
Basically I gained about 73hp over having a lid and catback. I feel that gain is pretty similar to other heads/cam packages (through cats and full exhaust) with similar components. Maybe I would have gained a few more with other heads and a bigger cam, but to me, it wouldn't have been worth the extra $ (at least $1k).
As far as drivability, so far I like it. It definitely pulls harder and longer throughout the rpm range. After the install was done, the next day I made a 4hr drive to St. Louis. Everything seemed to work ok including my SY3500 locking up like it normally does. Gas mileage may have dropped a tad, but not much. That probably had more to do with a few WOT test runs on the highway. I had a few punches at 80mph up to 100+, and it definitely pulls noticeably harder than before.
I was debating between going with the TR220 and Hammer Cam. After lots of research, I was strongly leaning towards the 220, but at the last min decided to compromise and went with the Hammer on a 114. I think it sounds sweet at idle. Even on a 114, it definitely has lope to it. There is some sewing machine noise, but to be honest with you, had I not read about the sewing machine noises on these boards, I never would have even noticed it. But, that's also the main reason why I went with the yella terras, as I heard they help quite the valvetrain. Only problem I have is on cold starts, it seems to surge and die. I've only done that once so far though and haven't had a chance yet to figure out the best way to handle that. Once it warms up, it still surges a little, but I was expecting that and it is tolerable.
If I had it to do over, I'd go with this setup again. Big thumbs up to Mark at Raging motorsports and Brian Tooly at TEA. I dropped it off last Sat for the install, and Mark had it ready for me last Fri evening. I also spoke to Brian at TEA and he spent about an hr of his time answering all my dumb questions.
I felt obligated to post this for my A4 brothers out there looking for info on a heads/cam setup without the huge cam (224+). Ok...feel free to flame away or ask questions as you please.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam dang.... i woulda thought 380atleast! Maybe the LS6 intake and ported TB would get your numbers up some. Ill let you know how mine does when i get them. I know with my et and MPH i should have atleast 360 cam only so im hoping 390 with the 1.5's
what were your flow numbers on the heads?

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Ed, with your bigger cam, I'm sure you'll do better than I did.
98TA, the ported tb and LS6 intake were done at the same time as heads/cam. I'll have to check with Mark to see if he still has the flow sheets on my heads. I totally forgot to ask about them. I think I still picked up a decent amt of power, but my biggest problem is the low numbers I started with. That's where I feel the missing numbers are...not from the heads or cam setup.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam im one of the biggest non believers in dyno numbers also
after i had my stall and etc my dyno came back like 277/300 but yet i was running 11.9 stock internally with bolt ons
did they lock your converter on the dyno? Cause its very hard to dyno a A4 and get the right numbers!

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam hey dont feel bad I dyno on a very conservative mustang dyno. My car only makes about 340 hp but it weighs 3400 lbs has 3.23 gears and still runs 120 mph trap speeds and in the 11.30 range.
The dyno I use is about 15% lower than most dyno jets around here.But it works great for tuning on.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Yeah, let your ET's do the talkin, not the dyno numbers. I went 12.o with 314 hp in my a4.
The high flow cats are prolly costing you a lil HP btw.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam I was going to ask if it was on a Mustang or Dynojet. Mustang will give your lower numbers. Not the best dyno if you wanna race dynomometers.
The track would be the best place to test anyways.
Congrats on your setup!

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Dyno was done on a dynojet.Did you have mark lock the convertor? You might try switching cams ,when i switched from the hammer cam to the raging 230 cam i gained 10hp at the wheels!

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Definitely low, but the cats could be costing you 10+ HP and unlocked converter costs a minimum of another 10HP.
Run it at the track and see how you do. It may be just fine.
My car dyno'ed low too, but runs decent despite only putting 378 HP on the dyno.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Its not the dyno, that much I can tell you. I feel your pain though, my car originally dynoed
267 RWHP, though it ran "normal" ETs. My first bowl ported heads (from a major board sponsor
) /cam setup dynoed 336 RWHP locked (no, that's not a typo) However - it DOES seems as though unlocked A4 dynos are almost completely useless....
The current setup (399RWHP) did pick up a solid 6 MPH over the previous setup (336 RWHP) which seems to jibe with dyno figures....

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Some folks will say locking a converter on an A4 car is a "Dyno Trick".
Well, thats absurd. An M6 has little to no slipage when on the rollers (acts like a locked converter). So, to get an accurate rwhp, the A4 needs to be locked. It still won't dyno quite as high as a similarly modded M6 due to a greater parasitic HP loss in the auto tranny, but, at least it will be closer to what a similarly modded M6 will dyno.
Bottom line.... Although we don't normally race at the track with a locked converter, locking it on the dyno gives a better idea as to how the [engine] is performing, irrevelant as to what type of tranny is being used.
Make Sense?

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam The numbers were about right. We didn't lock the convertor on the dyno and before results were 306rwhp with all the bolt ons in cluding headers. I feel the B+B catback and cats are killing about 15-20hp. Also if we locked the convertor there's probably another 10hp there.
I definitely recommend ditching the cats and get a cutout.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam I'd have to agree.
Locked verter is worth 10RW
!Cats easily another 5RW
That alone would get u 372RW.
Then add a cutout,I've seen cars pick up ALOT from dumping the B&B setup before the muffler.
I would guess another 6 to 10 RW with a cutout.
That would put u right around 380RW...
IMO that would be pretty good for S1.5/Hammer cam threw an auto.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam I have TEA 5.3's also..and TR224 cam.. I also only put down 366rwhp unlocked pt4000.
I ran 11.80 though so..??? full weight plus.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam i cant wait to see how mine does when my 1.5's go one LOL... MY et's say i have the power with just the cam so i wanna see if the dyno shows it. I know the heads arent gonna reduce my power LOL
when i dyno my verter will be locked cause I just wanna get the A/F right. If it shows 360, 380, or 400 I dont really car...
but if it pulls 360 and run 11.1's or so ill laugh my **** off... HEHEHHEHHEHE

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam Thanks for the support guys. Yes, I'm sure the cats are robbing some hp, but I thought the B&B was supposed to be a pretty good flowing exhaust. Oh well, maybe it's not since it's pretty quiet.
In any event, so far I'm still happy with my choices, and as I said earlier, if I had it to do over, I'd choose this same setup again.

Re: A4 H/C Dyno Results - TEA 1.5 5.3L/Hammer Cam I dyno'd in at 380 with GTP stage 2 heads and a baby 218/224 cam with LS1 intake, mac headers, tuning. I went w/the X1 cam and now am way over 400hp with this cam...I'm running a stock 98000 mile 4L60E with a Multidisc 4000stall vigilante.
I would check tuning 1st then go thru ur car...those numbers would make me puke...sorry man..maybe your car is a saturday car...ya know...one built w/noone home... ;-)
