If y;our getting an AEM than get a 3.5 bar map sensor......no one runs a MAf with an AEM cause they are a pain in the ASS to tune

 

[nissan crazy]

I am going to be running a AEM EMS ...sitting in the living room right now !!!

 

[spdracerUT]

If you're going to spend the money on an AEM and tuning for it, spend the money on a proper exhaust manifold! Heck, the mony is better spent on the exhaust mani and getting a reflashed ECU than the log and AEM.

Are you serious?????? wow.......:squint:
I would pay no attention to this rediculous statement. With the proper tuning system that will set you for the rest of the time you own the car, and the amount of options you have with this tuning system it is a much better investment in the long run than a EQL mani and the fact that you finally get rid of that crappy MAF. SO save some money and get a better mani in time. Tuning is probably one of thee most important aspects when building a car.......

So you're telling me every OEM out there is full of idiots because almost every car now produced uses a MAF based system, even Honda's now.

Sure, if you want to squeeze every ounce of power out of your car, go for the stand alone. Guess what, you'll be retuning it whenever the weather changes if you want optimal power. You're going to spend a fair amount of money tuning the cold start, A/C running, etc on it too. And if you actually performed the calcs on how much of a flow restriction the MAF is, it's hardly anything. I'll bet you'll gain a lot more HP going to a EQL manifold and using the stock ecu than using the log and the AEM.

And if you want reliabilty, you can't bet the stock ecu. Bang for the buck, a properly retuned factory ECU with the EQL will beat the log with AEM. Heck, get Calum's ecu and tune to your hearts desire. Cold start and a/c is all taken care of already.

Let me ask you this, how is the AEM any better than a factory ecu that you can adjust the timing and fuel maps? You can go speed density you say? I'll counter that the gains in flow by eliminating the MAF are significantly lower than the gains that'll be seen by going to the EQL over the log.

Yeah thats exactly what i said.......

Sure, if you want to squeeze every ounce of power out of your car, go for the stand alone.

Well since thats why we are all here which is to optimize our AFTERMARKET cars and the rediculous parts we put on them. So I'll agree with that.....

Guess what, you'll be retuning it whenever the weather changes if you want optimal power.

Well how many AEM EMS systems have you done then sir.....yep exactly what happens when the weather changes, back on the dyno again.....wow

Oh big deal about cold start and part throttle stuff, cry me a river, takes a couple hours.
But I would be up for a dyno challenge in all seriousness to put the same mods together on a motor with the only difference being your motor having a factory reflashed ECU with an EQL mani..... and my motor having a log and an AEM......just curious as to what the results would be..... would you be down?

And if you want reliabilty, you can't bet the stock ecu. Bang for the buck, a properly retuned factory ECU with the EQL will beat the log with AEM. Heck, get Calum's ecu and tune to your hearts desire. Cold start and a/c is all taken care of already.

You'll pardon my asking what are you exactly saying in that last paragraph cause your sentence writing ability seemed to deteriorate a bit.....Im not trying to be a dick just wondering what you were saying......

well the log mani was already purchased - i was pushing for a tubular but its not too terribly bad, the differences arent enough to hurt us in the long run

yeah, we have definitely worked with cars enough to know the importance of tuning - there will be no skimping on the tuning-side of things, and i highly doubt we will have to adjust the AEM so much for every little variable .... the shop it will be tuned in, as well as most of the local guys have had great success with standalones like the AEM for daily driving

 

[Coheed]

I recently made 436whp on 24psi on the gt3076r turbo on a dynojet. It is not the amount of power that others are seeing and I don't know why that is. But on 18psi on 91 octane the car made 397whp. So it is pretty much a 400whp daily driver and I am still using the .63 housing. Log manifold.

There is no doubt that a better intake manifold and a tubular would yeild very good gains. But the limiting factor now is the tune. I have a guy local here that can tune my car and make 50whp more prolly. same boost and everything.

 

[ca18 bluebird]

ok i was going to not say anything here as i am a big believer in spending extra money on tunning.

BUT AFM HAS MORE RESOLUTION AND WILL GIVE A BETTER, MORE ACCURATE TUNE THAN MAP! PERIOD!

this is coming from someone who spent big dosh on an autronic!

sp many people are missinformed and think map is better than maf, they are wrong! it can be in certain situation, but isnt always!

what about all the negatives of map? like for example it doesn't take into consideration the dew or water content or temperature of the air, where maf does. has to be retuned after every little mod, ie intercooler or changing a a muffler, where maf will have a degree of adaption.

map is good on big power turbo cars that get air reversion back to the maf altering the signal. or where the afm is simply a restriction.

but afm is superior over map in so many ways, this is why oem companies, with their billion dollor budgets (much more than aem could ever dream of) choose maf based tunning systems

 

[venom_5]

i know the MAP has less resolution, but with the AEM it seems that MAP is just the route to go ...

do you have an alternative that will work with the AEM? if not, we were considering a Haltech simply because we have several friends that have loved them ...

by the way, this is the JGS manifold i was talking about:

its not the piece-it-together ones they have now

 

[spdracerUT]

That manifold looks halfway decent; like a hybrid between a log and tubular. Just having each cylinders' flow separated into individual tubes should help out significantly compared to your typical 'log'.

Given the option of a tuneable factory ECU, and a standalone, I see no reason to go with the standalone for a daily driven car. Hell, even for a track car; the majority of the time attack Evos and STIs in the US use factory ecus and keep the MAFs. Why not? They're perfectly capable of controlling the bigger injectors and you just go into the fuel and timing maps to make whatever tuning adjustments you need. Other maps like temp correction, injector latency, etc. etc. all completely tuneable. On Hondas, Hondata is the way to go.

From a cost and time standpoint, the existing programs for the SR20 from Enthalpy and JWT are really well developed. Enthalpy has tuned for 93 octane and JWT for 91 and various race gas tunes. Plug-in-play and very low downtime (no rewiring the harness, etc).

 

[jp]

What I would do
gt35r 0.63( HTA comp housing from FP) its a better match for 450-550whp than the 3076
Enthalpy reflash ecu(cost efective$$$$$)
hks 272 step 2
Greddy intake manifold
Nismo FPR
2 WALBROS in tank or other more powerfull fuel sistem
at least 800cc injectors( Im pretty sure its can be tuned with Enthalp ecu)
Big fmic
external wastegate etc
Here is a dyno on a sr20det between regular 35r 0.63 vs 0.82 same dyno same setup equal boost etc.
Expect to get aprox 200-300 rpm of better spool with the HTA and about 20-30 more whp on high boost.

There is many other ways to get a better spool if you want that .
Cheers

 

[venom_5]

the problem with the GT35R's is that they dont make power until like 5k as shown in the graph....

i think we'll be happy with the GT30R, if we fall short of 600whp on race gas it wont be a big deal

and yeah, that JGS mani isnt the typical log one that everyone thinks of - thats why i posted the picture to clarify

 

[MR-4Door-SR20DET]

Making power around 3500K would be ideal for me running a T3/T4 turbo.

^Is this venom_5 from SSI? What you doing over here? Who project is this?

 

[jp]

The FP turbo probably will have 300lbs of torque at about 4200-300 rpm , also you can do a twin scroll 35r as well... anyways
Good luck with the build.
Cheers.

 

[venom_5]

^Is this venom_5 from SSI? What you doing over here? Who project is this?

yea it is ... its a secret build, for now - gotta keep it on the DL, but youll definitely see it, maybe even in person!

yea, its definitely something to consider ... we've toyed with both ideas, idk for sure yet - GT30R is probably gonna end up being the route .... like i said, if it turns out to be a failure we can always upgrade down the road

 

[MR-4Door-SR20DET]

I'm rolling with a T67 of some sort. I call that the street r*ping turbo! So is this S14 yours or is it bdp07NWH's you searching for? I just did a search and looked up some info on SSI. Redtop or Blacktop?

 

[venom_5]

its neither mine nor bdp's

its a red top

ok first of all i like that manifold, looks very good for spool and shouldn't affect up top too much.

however the secret to building a good car is getting all the peices to work together in harmony. so basically aim for everything to be at its limit at the same level. with that in mind i would run a .63 housing with that manifold. if you where running a long runner equal legnth tubular manifold, then yeah i would say maybe go the .82. but with that manifold i think it would be perfectly suited to the .63.

even look at the graph posted with the gt35r, look at the difference in power down low, and look how nice the tourqe curve is of the smaller housing and the 35r is more suited to a .82 than a 3076 is as the housing will become more of a restriction. In fact i would would recommend a .82 for a 35r in most cases

so why run a nice looking manifold designed for spool with a laggy .82 housing? especially when it wont be the bottle neck in the set up?

also haltechs rock, but really as long as its a programmable ecu anything from haltech, autronic, aem even top a real time remap will be fine as long as its tuned by a good tuner. i would rather a real time chip in the standard computer tuned by an expert than a motec tunned by a chimp. but it does depend on what features you need? you might want to run antilag, flatshift, nos etc and need the auxiliaries.

 

[venom_5]

we wont be doing anything fancy like anti-lag or that stuff ... but we want a nice standalone like the Haltech or AEM so that the opportunity for expansion on the build is there - would hate to have a chipped ECU with a piggy back and then want to build more, and have wasted all that money you know?

as far as the .82 AR versus the .63 - do you think the .82 AR will really be THAT laggy on the GT3076R?
considering its a BB turbo, the manifold really isnt classical log style although its not equal length tubing either, and the valvetrain wont be geared towards top-end, i would think their should be decent flow in the 3500+ rpm range...

im just worried that with a .63 AR housing it will hit the peak, whereas with the .82 AR housing we will still be well within the ability of the turbo, with no need to upgrade any time soon before we were to upgrade other parts
