New Best: FP 3575 + AEM magic

[red91gst]

Nate the beauty of a standalone is that you can get GREAT driveability even with big cams, 950cc injectors, while make 550+ hp. Something you really don’t get with piggybacks.

Totally agreed, just questioning the need on a "race only" car. I dont think Curt drove his car to work on Friday, wonder why?

EXACTLY---MId 8s... thats when you need a Standalone. If you go even faster.. then its time to praise the AEM or other unit for getting you there... not Mid 10s. thats my point.. How many other people have gone mid 9s or lower on a DSM?? 3.. thats right two on nitrous.. the other ...Curt Brown..no nitrous, a stock ecu and VPC. Unless u feel u are good enough to be in the top 3... why do u need it then?

The supra guys use to think this way as well. They always shunned any type of stand alone because the VPC GCC combo was good enough. Well many of them have turned to the AEM EMS and are having alot better success with it vs. a piggy back. If you have the capability to tune stand alone and AEM has a pretty good support system setup, stand alone is ALWAYS better.

If you like piggy back thats fine, thats what works for you however a VPC car WILL make more power on an AEM. This is fact and proven over and over with Supra's and they talk about nothing but HP over at supra forums. They all run 12's but the AEM cars make 800hp and run 12's vs the VPC cars making 700hp running 12's. :laugh:

My point is why compromise? My buddy HighPsi91 runs 9.9@148 we both drove an hr+ on pump gas traveling on back roads to go to a DSM meet once. No need to have a car that you can only enjoy on the track.

Oh man, I gotta show my buddies this thread now... they'll get a kick out of this one Jim.

What i am saying is if it has been done without it, its the persons ability to Tune.
I have built cars from the shell up. Obviously there is tuning required at that point ..

All the piggyback stuff gives you extremely limited ability to tune throtle transition, off boost driveability, etc... My whole point isn't about WOT performence, in honesty tuning at WOT is very easy. It's the fact that there are almost always compromises in driveability with a heavy modified car that uses piggy back computers.
Just because you built a car from a shell doesn't specify what you did to the motor, you could build a stock car from a shell
None of you guys ever actually said if you had a personally used a standalone before. I find it funny that someone would knock something without first hand experience with it.

 

[TurboSpoolinIns]

Fast guys get the new shit first so they can make big power and drum up demand. That isnt a hard concept to understand is it?

Well, not necessarily true. If you called up FP and asked them for a turbo, they'd most likely sell you what something that suits your needs/goals. BTW, nice color/car RDRKT, coincidence how we run almost identical ETs and have almost identical cars (I know you had yours first)


Anyhow, Leon, congrats. It's nice to see these DSMs get faster and faster by the week.

Found the supra comment funny.

All of this talk is application specific. A full standalone system is not going to benifit a lightly modded car anymore than a airflow converter is so long as there are no huge compensations made.

However, I would rather tune a standalone over a piggyback anyday. Piggyback's have so many side effects because of the way they are making adjustments to the airflow signals. I've never understood how people expect to tune a car with twice the injector size and then telling the ECU that it's only recieving half the airflow it actually is. Besides air to fuel ratio's are not where power is going to be gained while tuning and since that is all you're able to adjust with a piggyback they're really only good for making the car run safe and not actually making power.

Now I'm going to go twist knob's on my maft.

congrats on whooping on all the other 10 second monsters...i know barry with the yellow rx7 and i dont like him personally... he hates loosing....trust me i know i beat his daily driver black s2000 with with gold wheels in a street race and i was only in the 14s... at first i thought it was luck but then i heard he had a 10 second rx7, then for sure i knew i could drive hella good + i beat him for his 40 dollars... you should have seen his face
anyways congrats leon
p.s. tell your friend chris blanc to open up his new shop soon because im ready to put my motor back together

And there is always DSM Link which has now run into the 9's.

Big congrats Leon!!!

Thanks again guys. Only my beloved FP3575 has met its untimely demise this past Sunday, when I took a day trip to Island Dragway in NJ.

After my first 10.30 @138 pass (during which, the turbo just didn’t sound “right”) I saw a lot of smoke coming out of my exhaust. Looking under the hood, we immediately found a bunch of broken fins on my FP3575 turbo.

The cause of those broken fins became apparent pretty quickly: my turbo sucked-in BOV to HMBC vacuum line! Foolishly, I decided to leave my CAI and air filter off the car, thinking: “Oh, what is the worst that can happen?”. Well, now I know what DID happen...

Other than destroying the turbo, it had two over effects on my car:

1. My wastegate lost ALL boost control, so it was shut closed!
2. My BOV lost most of its boost pressure, so it must have been opening at some point, making turbo work even harder to maintain that boost.

AEM log (log www.reitmanracing.com/grnmch/10.3_at_138_blown_turbo.stf ) showed some pretty interesting things:

1. From the moment that I lunched the car, boost got up to 40psi!!! So this must have happened during my quick burn out.
2. As my run progressed and turbo lost more and more of its blades, the boost dropped down to 39psi
3. My AF was round 10.8 throughout the run.
4. My 1000cc injectors were around 85% IDC.
5. I had VERY little knock related timing retard.
6. My fuel pump(s) kept-up with these amazing demands!

This was definitely the case where my latest round of building-in extra capacity into my fuel system has saved my engine!

Other observations after the run were:

1 Spark plugs (BPR7ES)looked AWESOME!
2 I did not push coolant! (Cometic HP gasket on “mirror like” finish on both head and block)
3 I DID push oil out of my zip-tied dipstick, from so much blow-by.

Someday, I actually might tune my car to run 40 psi of boost. But for now, this was just a weird fluke and I am glad that my engine lived to see some more passes. In ether case, I find it an unbelievable co-incidence that I ran virtually identical ET and trap speed to my previous pass, which was clean!!!

Overall, I am VERY impressed with this turbo! It made 40psi of boost on a broken compressor wheel while the BOV must have been leaking! It is too bad I ruined it before I had a chance to even come close to maxing it out .

BTW, after this turbo was gone, I installed my trusty 14b hoping to improve on my previous best. Well, that didn’t happen (my AEM tuning was WAY OFF), I ran the best of 11.9, missing a 4th gear. But I was able to determine that my engine is still OK (there was no more smoke).

 

[ITSME4G63]

thats still ####en fast on a 14b, 11.9 woot.

 

[CanadianTSi]

Sucks about the turbo, gonna replace it with the same thing?

Also how much boost do you normally run?

 

[awd4g63]

Very nice, dude

I was just reading a magazine at work today with your car in it. It was the SCC issue a year or so ago when they have the Ultimate Street Car Shootout entries.

Again, very nice

 

[GRNDSM]

It is, for most people, but I have ran 11.64 before.... And this time, I was almost 120lbs lighter and I was using Hoosier tires, which were giving me .10-.12 improvement in the 60'. So do the math

Normally, I run 32-33psi of boost on the FP3575

 

[ITSME4G63]

Normally, I run 32-33psi of boost on the FP3575

That is not enough.....................and you know it.

 

[GRNDSM]

That is not enough.....................and you know it.

Well, yes I do know it. But that is where I was am at this point . Though I guess I now know that my fuel system is definitely up to a supporting 40psi!

 

[ITSME4G63]

What a way to find out ey?

Don't want to get the arguments started all over again, but I do want to say that having a standalone, while not absolutely necessary for most people, makes tuning the car a heck of a lot easier. I have DSMlink, which is pretty close in functionality to a standalone, and the combination of datalogging and control of fuel AND timing with no interference between the two makes it stand head and shoulders above the typical piggyback system. Did I need DSMlink? No, but I definately won't do without it anymore. It's hands down THE best $600 I spent on the car.

Plus, nothing impresses the ladies more than hooking up a laptop/palm to the car to tune it.

 

[1_vicious_gsx]

I can only say that going from a s-AFC to DSMLink, and then to DSMLink V2 is much better than the s-AFC piggy back. Much more control over many other parameters instead of just fooling the ecu into adding more fuel. I wouldn't go back. If I weren't in a state that requires ODBII inspections, I would move up the the AEM EMS unit without hesitation. Don't think I haven't thought about just taking the ticket for the "no inspection sticker" either.

Yes i agree the difference between a afc and dsm link is apparent.. But thats comparing apples to apples.. They are both Piggy backs And dsm link doesnt have the features that a stand alone has..thats comparing apples to oranges. I will be the first to say that AEM is a very benificial tool.. But the original arguement was at what point is it really needed. Yes u can make more power out of AEM, But it doenst make power out of a turd. if you drop 1-2 tenths in the quater after buying it... was it worth the 1400.00 plus??
that was the question.. I think some people purchase it and see no gain.. but more for the rice affect. but not to continue the arguement, just clarifying the last two post were about dsmlink .. yes its great.. i have it too.. but its no stand alone.

DSMLink is not a "piggy-back".
DSMLink doe have alot of the features of a "stand-alone".

 

[Mike 99GSX]

DSMLink is not a "piggy-back".

Techically it is a piggy back since it is still working in conjuction with a stock ECU.

 

[1_vicious_gsx]

Wrong. :thumbdown

DSMLink is the ECU. There is nothing external about it. It's all in the ECU, just like the AEM EMS unit.

If you say so chief.
