Cpe Full System Dyno Results

[MUSOM]

I just arrived back from my install of the new CPE FMIC and standback EMS. I can't say that I am completely satisfied this go around. It may in fact be my fault, as I didn't have the time or resources to do a pre-FMIC dyno run like I was wishing to do.

The install took place at the CPE shop yesterday evening. There were 3 guys working on my car from about 7:45 to 11:15 or so. It took an experienced tech about 3 hours for the standback install, and the front mount was a little less involved and took about 2 hours or so. Seems to be that the FMIC is a DIY install. It was not a big deal at all, as everything went on smoothly. The EMS wiring did not look pleasant, and I would not attempt it unless you at least have some electrical/wiring experience.

As for the dyno results.....performed at altered atmosphere in gaithersburg maryland the following morning. On a side note....all hotels were booked that night...so yes....I slept in my car. (freak) Customer service was good, but slow. I arrived at my scheduled appointment at about 8:45 am and did not leave until about 1 pm. Things were just very busy at the shop and Mike, the owner, had other matters that were deemed more important than mine.

So I did about 20-25 pulls on the Dynojet AWD dyno. The bypass was placed in the CPE EMS for a baseline pull. This baseline still included the FMIC mod.

236 hp and 250 torque was with the following mods:
CPE CAI
CPE TBE with mufflers and high-flow cat
CPE FMIC
*temp 85 deg, humidity 11%, app. 94 octane, new dry fit CPE air filter
Also, baseline AFR was horrible, as it dropped below 10:1 past 5500 rpm.

After tuning with the CPE EMS and making two separate maps (explained below) I reached 264 hp and 276 torque. Again my mods are all CPE....FMIC, CAI, TBE, EMS.

The results:
approximately 28 max hp and 26 max torque with the CPE EMS tuning. However, there is much more to be said by the dyno sheets. If you look at RPM ranges of 2500-6500 rpms, there is about a 20-25 hp and 20-25 torque increase through the entire parameter. Another key, it EMS held 245 hp (or about 90% of total power) up to 6400 rpms.

My feelings:
I am terrible upset that my baseline pulls were not as high as I expected. I honestly thought I would throw a baseline pull of 250-260 hp, and be close to 300 with FMIC and EMS tune. CONSIDERING...the CPE website has a MS6 dyno with ONLY CAI and it was 233 hp and 264 torque. With my FMIC, CAI, and TBE I was only 3 more hp and 14 LESS torque. Something is not adding up. Let me elaborate via CPE's website....



MOD - CPE CAI .......221 BASE HP.....233 FINAL HP.....12 GAIN HP
MOD - DOWNPIPE.....210 BASE HP.....247 FINAL HP.....28 GAIN HP
MOD - EXHAUST.......221 BASE HP.....247 FINAL HP.....26 GAIN HP


Now let's compare with my mods and results.

MY MODS.........TOTAL FINAL HP

CPE CAI,
DOWNPIPE,............236
CBE, AND
FMIC


WHAT the HELL happened to my horsepower. I would also show torque, but I'm getting more frustrated as this new post continues. I am smart enough to know that bolt ons are not additive when it comes to dyno numbers, but WHEN THE HELL DID THEY BECOME SUBRACTIVE?

So take a look at the results of the dyno and let me know what you all think. I need sleep at this point. And another thing, I'll be going to the track tomorrow to see what kind of changes I can get on the 1/8th. I'll post slips tomorrow or sat.

dude admire your persistance, if you did end up with 276 4wheel horsepower is that really that bad?????

 

[MUSOM]

NO...not bad. I just expected more and got my hopes up. that's all.

That looks about right. Since you didn't do any baselines on that dyno, you're not going to know what you started out with.

The FMIC isn't going to add much if any HP directly, but it will let you tune more efficiently. You'll get far less heat soak, and you will have more usable boost since you BAT will be lower.

You can't add the 3 different mods and their individual HP to get a proposed baseline like you are.

You can't really compare dyno runs from 2 different cars.

The reason you are using a dyno is to tune your car.

You'd have a more reasonable argument if you had done a stock baseline dyno run on this very dyno before you modded it.

The point is this, dyno your car stock, and then do your mods, and then run the same dyno again to see what gains there are. That is the only way to accurately get any feedback on upgrades.

Think about it, you have almost 280whp. The stocker is rated at 274 at the crank, you are putting out 330+ to the crank, that is a really NICE gain.

Try a dyno tune session with 100 octane!

How much boost? That is an important fact for a FI Car. If you drive the car with 16-17psi these are very good numbers. But if you drive it with 19-20 psi I can tell ya I've seen the same numbers with only a ATP DP, a Cai, a TMIC and a EBC on my car. And my car is running extremly fat.

 

[chriscecc914]

im glad to see that some people can get there hands on an FMIC and others cant.

Its simple enough to say that we cannot deny the fact that the turbo sucks in this car and it needs to be replaced. If we ignore this fact, we will not make good power.

 

[MUSOM]

I did dyno with 94 octance at about 256 awhp and with 100 octane at 264 awhp. It does make a difference, but I also advanced the timing slightly with the 100 octance, that helps too.

PSI was set at 17 and i got 256 awhp, but 18 psi (with 100 octane and advanced timing) gave me the 264. I tried 19 psi, but it made only slight, and "not worth the risk" gains throughout the powerband. We're talking like 1-2 hp or so.

Hey bud, I'm sorry that you are upset about the return on investment. You need to remember that Dyno's are all a bit different, this one might run on the low side... you just never know.

Anyway, I wanted to help you feel better, your 1/8 time is ----8.66 @ 79.5 mph ---- so your 0-60 time is 4.93 seconds. That is faster than a Mustang GT with 300 HP, and with the additional usable HP you picked up, you could very well see a 4.5 second 0-60. http://www.markviii.org/~nightsky/sixty.htm

Either way, that is very impressive, your car is tuned now and you know from CPE all your new parts are extremely well made.

Last but not least, when you go to get the bigger turbo... call me so I can make the trip with you!!! I need a damn vacation. (drive2)

Dave, this is the first time that I've seen the dyno graph. I immediately took notice of the power gains at 3000rpm and 6000rpm. It looks like you made almost 70lbft. of torque at 3000rpm, and it looks like 40hp at 6000rpm. Even though your peak numbers were far from your target, I think the power gains elsewhere are substantial after the tune. That should provide a nice drop in your ET tonight. Keep us posted! (cheers2)

I've always been of the belief that dyno's are for tuning. I go to the track to see what the real world gains are.

 

[dadasracecar]

There seems to be a lot of variation in the power output of these cars stock. Just from the numbers you posted from CPE's website there is an 11 hp difference presumably at the same dyno. I've seen numbers as low as 196 whp stock and as high as 235 whp stock. That's a huge variation.

In any event, the dyno graph you posted looks like a really nice useable amount of power. Like Jordan said, the improvements at 3K and 6K are awesome.

The same thing happened with my car. I was only 5 hp over peak with the Standback but made ~20 whp at 3K which steadily declined to 5 whp at peak.

Mike said these cars are pretty tapped at ~5500 so a gain of 20whp at peak is nice. Can't wait to see your times.

 

[VinnieBeachbum]

dude keep your chin up.

Thank you for the DYNO's. Very informative. You gained a shitton. Hopefully you will be very impressed upon when you get back from the track.

 

[MUSOM]

Looks like the track night will be delayed until next week. It is storming now, and doesn't look to let up anytime soon. Next thursday night is street night at the tracks though. Guess we'll have to wait until then.....

Is the difference in the cars or the dynos is the question?

 

[jcgemt2003]

I was hoping to see a little more than that with the fmic...what the hell. It was close to what we expected though musom so dont get to down...Your gonna be running some low ass 13s...Next thing on your agenda should be a bigger turbo....mine was supposed to be here today but you all know how that s*** goes.

 

[07MS6]

That's all you got? Sorry man.

 

[MUSOM]

I hear ya. I'll see what 264 awhp can do a tthe track. That will be the true test. It was too rainy tonight, so next Thursday will have to be the day.

That's all you got? Sorry man.

Its hard to compare results from different dynos though, I have a friend, we took his GTO to two different dynos on consecutive weekends, the first dyno told him he was putting down a little over 450 hp to the wheels. All though that number sounded great, it also didn't sound right for what he had (intake, headers, exhuast) it sounded like to much. So the next weekend we took it to a more reputable shop, there he put down 375 to the wheels. When the car is only rated 350 at the crank (first model GTO with the 5.7) that sounds more appropiate.

Trust the track times, the only way to figure out how much you really gained was if you did a baseline dyno with NO mods on the car. Either way, lots of respect for all you've done man! I wish I could get more for the car, but I have this affliction that makes me spend all my money on other junk, its called my wife

for starters you should make sure your car is running right and take off that VTA BOV on a MAF sensored car!

 

[Chris-BE]

It will be fine. Besides they tuned out most of the VTA issues. At worst it will run rich for the moment the air is released no big deal.

I'd suggest taking everything off, and re-dyno, and add everything back.


And holy torque BATMAN! You car should feel like a rocket ship now. Man that torque graph looks badass! Your car doesn't fall off anymore either, it stays near peak HP after 6000rpm's. That is SICK!

Where is my FMIC?


Don't get stuck on having a DYNO QUEEN, you numbers are nuts! I'd expect high 12's with no problems on 1/4.
