View Full Version : Dynotune Results: TR224

04-09-2004, 05:20 PM
No dyno tricks on a hot day in San Antonio, Tx. So these are my real world numbers. I am happy with the numbers, now i just need to see what i can do with it. I gained 46 rwhp and 29 rwtq.

pervious numbers minus cam were 340 rwhp and 349 rwtq

uncorrected 386.8 rwhp 377.8 rwtq
corrected 379 rwhp 370 rwtq
my A/F ratio is running smooth along 13. if anybody can host some dyno pics for me let me know.

all mods in sig

very nice numbers indeed. what are your corrected number?? It sorta gives us all a standard if you tell ...

Andrew, Congrats on that cam man! I know you got it for an awesome deal im sure it was a great investment ;)

his corrected numbers should be around 378rwhp but im not quite sure.

I saw the dyno graph and noticed something weird. His cam is making peak rwhp at the rev limit! It seems like the tuner did not change the rev limiter settings and its still at 6000. I was thinking the tuner needs to raise the rev limit up higher. In other words, andrew would probably shift at 5900rpms when racing (to avoid hitting the rev limiter) but then he will never be able his car's PEAK rwhp numbers :scream:.

I would suggest for Andrew to go back and raise the rev limiter to 6400rpms at least that way he will spin his motor a little more and shift at 6200 taking advantage of his peak rwhp figure a little before its time to shift (leaving 200 rpms as a measure of safety). What good is it to shift a little sooner? He cant keep tapping the rev limiter everytime anyway and that might even slow him down. Either way the rev limiter needs to go higher. My rev limiter is set at 6700rpms on my car but I shift at 6500 (although i have the TR224 114 cam - bigger LSA)

Anyone agree to what Im saying? we need some more experienced feedback here and help my buddy go faster :). I could be wrong on my advise but I kinda doubt it. Wish I could see the graph more closely to judge but as far as i see its still climbing from 5500 all the way to 6000.

Good news is you might be making your peak rwhp at 6200rpms so you might be able to do even better. Only way to know is to dyno it.

Either way, enjoy your new cam and good luck on your future mods :)

Ok I did a little more thinking about this.. did you go with stronger pushrods upon cam purchase?

You will need better rods if you want to rev you car up higher (i did it to be on the safe side but my rev limit is at 6700). I figured maybe you did the cam install at the same place you dynoed the car and maybe the tuner thought you dont want to go higher than 6000 on the stock pushrods as they might bend?

04-09-2004, 10:58 PM
Nice numbers... You guys ready for tomorrow? Hey Ahmed.. You gettin up in the morning for the meet?

04-10-2004, 01:12 AM
yeah im coming dude sorry for the late reply on the PM.. was super busy.

04-10-2004, 04:50 AM
yah i got the hardend pushrods from TR racing and valve springs to handle the lift so i should be able to shift at 6700 where the cam claims to end its powerband. Corey (my tuner) told me that he set the rev limiter at 6500 and i should be shifting at 6200-6300. can u tell by the dyno that its not set that way?

maybe then you didnt get the updated dyno sheet or something?

They dyno sheet shows the curve stopping at 6000 not 6500 or over?
See attached.. I found this somewhat confusing.. but i might be wrong..

Nice numbers Andrew! (My benchracing skills did predict the 380 range) You're going to need to take me for a ride. Wo0t!

04-10-2004, 11:46 AM
Good Numbers for your mods! The TR224 is a great cam for a daily driver that likes power also. For best results shift at 6400-6500rpms with the TR224.

Here's my Dyno for comparison.....

04-12-2004, 08:20 PM
SAE corrected 379 hp 370 tq

rev limiter set to 6700. so ill shift around 6400-6500 rpms

04-12-2004, 08:40 PM
you should redyno it with the new rev limiter. it'll give you a better idea of when to shift

04-12-2004, 09:33 PM
sounds good. congrats.

i would like to know if this cam smooth like a stock cam and with a stock engine. what HP and TQ i will get from this cam. i'm planing to do porting to the heads and the intakes. plzzzz help me.

04-15-2004, 12:04 PM
Nice.. that is about what I got too. My shift points are at 6450 ;)

04-15-2004, 12:26 PM
thanks deez, i like ur ET! :) :)

04-15-2004, 12:47 PM
Thanks Tripp... keep your eye on that too. I should be cutting it down bit by bit. Good luck

WAIT A MINUTE! DeeZ, Your dynoing 373rwhp on an auto?!?!

Yep I sure am... with a locked converter.

355/436 unlocked

04-16-2004, 06:00 PM
355/436 unlocked

LOL i bet you meant 355rwhp/336rwtq

Good numbers, awesome time, and NICE 60 ft!

Nope sure didnt... the 436 is from the coverter flashing :judge:

The peak # is nice but what I really like is the Tq. curve! That is gonna be really nice on the street. I would shift at 6400. Nice job.

04-18-2004, 12:10 AM
can someone quickly explain the unlocked and locked torque converter stuff?

why 436rwtq? Dont understand. I never looked into the automatics I guess.

04-18-2004, 05:04 PM
the torque converter is our best advantage. It stores the "flash" inertia and lets loose when you mat it at the track, hence why m6's are always playing catchup off the dig.

I can simply floor the bitch and it hookes (ET's). my dyno below is with a very similar cam (224/226) not much difference. the STR generates massive low end torque to cut those great 1/8th mile.

Typically an M6 car that can launch at 6500rpm on slicks can run the same 1/4 as a automatic on nitto's with a good driver (its not easy to hook nitto's with so much torque).

My 365whp not exactly tuned (shift points) and too small verter ran best of 12.163@112.60mph on nitto's. hotlapping on a +40F day i got best of 12.269 with ET's (ECT/TRANS temp =225 ouch!).

You can see the stock versus tci ssf3500/cam/boltons/gear mods in my sig dyno.

I can totally annihilate the nittos at 25psi hot at under 30mph by pressing the gas.

the 12.163 was shifting at 6089rpm and dropping back to 4600. This is NOT OPTIMAL for such a cam (see my dyno). Now i shift at 6600 dropping back to 5010. STILL NOT optimal. A bigger verter would yield a shift of 6600 -> 6000rpm (way more optimal).

The whole idea is to run the 1/4 mile (after hooking hard) at the maximum average peak whp. For you M6 guys that means ASP pulley, lightened flywheel and damn fast shifting. For us A4 guys that means buying the right verter from the start :) Something i did not do... (to small).

unlocked A4 dyno's are all that count, because unless you have superman transmission, its not likely you will shift with the TCC locked up anways.

I had torque management on both runs (12.2/12.1) that reduced my timing to ZERO on shifts. This has been dealt with reasonably. I have 71K on my tranny so im not expecting it to be as fast as a new fresh upgraded rebuild. Just dont have the coins.

Nitto's are basically near impossible to hook on my setup. I have too much off the line torque. ET Streets make launching way easier. idle at lights, when they drop punch it, and hold the hell on.

Good tuning goes a long way too ;) And keeping the trans (A4) fluid cool and ect's cool. I've reprogrammed my fans to work a little better now.

I may try locking the TCC at the track (30 seconds to flash a new program) and see what she does. If i nuke the trans, well it has 71K on it, no biggie. rebuild time.

Tracks around here are not like texas, so we don't get the DA advantage some of you guys have. Same with prep. When you got 400 cars, and 30 are running slicks, 20 dr's, and the rest street tires (going thru the water box lol) you can't expect a track to respond as well.

365whp unlocked on an A4 with some mileage is an 11 second card TUNED properly, and pushing the limits (of motor/trans/traction). My goal is 12.0 consistent, as the track closest likes to perma-ban you for no cage and i'm not gonna put more weight in.

I don't know DA. But with the sub-par tune (low rpm shift 6089 & Tq mgmt) at 50F temps, after about 200+ passes, i pulled the best on my nitto's by letting the car cool down a little on nitto's. I spun them regardless, but still got my 12.1.

Common bs = a4 car's cant pull on m6's with similar mods. Sorry. If you can program your TCC lockup and shift points, you can very much hang with a M6 on a roll. But we all know racing from a roll is for pussies ;)

I got $4000 into my car. The car cost $12K (66K miles) that money includes all the tuning (pro) install, retuning (pro), hptuners, and other goodies. its my daily. It runs 3653lbs raceweight. I think with nitto's i can throw a spare tire in the back or something to get more traction.

There's alot of misconceptions on A4's. People say they are easy to launch. I will bet your $20 that you can't run as fast as me on my A4 if you've never run one before in 4 runs. It's not easy on nitto's. Everyone thats tried was like "whoa this isn't easy".

Now with ET's its a totally different story. Burnout -> idle at lights, stab and steer. Real easy. My motor does not have enough TQ to blast the ET's.

I could spend $600 on a 4000rpm stall and do 11's easy all day long. I could spend $1799 on heads and do 11's all day long. But again. I dont want a cage. My family rides around in my car. It's not for me.

Here's the basic gist of your answer now that my rant is over:
Tuning: Locking up the TC can allow more finesse tuning.
Driving: You will not drag/etc locked up, you will destroy your tranny unless its a superman tranny/verter combo. Some are. Mine isn't.
Launching: Always unlocked, the inertia from flash stalling the verter is what gives us the 60 foot time that requires SERIOUS rear end/clutch M6 work to achieve.

So i see it this way:
Dyno the A4 unlocked, its what your gonna run it as (most people).
Dyno the A4 locked, dyno queen numbers, bench racers etc, or a trans/verter with balls. NOT recommended for stock verters nor trannies unless you like to rebuild them.

feel free to argue, i don't claim to know it all, but i've watched/get opinions from skilled m6 drivers and seen the results.

12.6-13.0 from an m6 driver on my car.
12.268 from me on the same day, etc, not cooling it down.

I think the biggest misunderstanding people have is that A4's are easy, there's no skill involved, and thats b/s for most "cam/bolton" a4's.

There's no b/s in my dyno. It was consistent. Never underestimate a good hookin' A4 with low unlocked hp #'s. It's very likely a 380-400whp M6 with 12/8.8/9 inch ET streets and superman clutch and great driver will get pwned by a 350-365whp a4 on nitto's and a DAMN good driver who can launch the nitto's and roll the throttle to keep it from spinning.

oh yeah, and i can't use the line "i missed 4th". Hell i never get into 4th. I can't miss 3rd either unless i torch the tranny.

samz28, thanks a ton for the explanation. I learned a lot today thanks to your reply. :cheers:

You also cleared a lot of BS I thought I new about A4s and verters as I too thought launching those is a piece of cake.

From your mods I can see an EASY 11 sec car. :)

Again thank you, good post, nice car, and great 1/4 mile and dyno numbers :thumb:

What did you dyno before the tune? I'm wondering how much power is a tune worth.

04-19-2004, 01:18 AM
with the tune u will see A LOT more rwhp and rwtq through out ur powerband. u would only see a little gain in peak rwhp with a tune.

04-19-2004, 04:53 AM
on my FIRST tune it made 350rwhp and 360rwhp after more and more tweaking.

This was before the headers install.
