upping boost.

[jestermsp]

has anybody ventured to up the boost in a cx7 yet? i am very tempted cuz the rdx take off like a rocket in comparison. i aint havin that.

[evo_mr2006]

I'm in the works on custom fitting a front mount intercooler and i have a boost contoller that i will be installing as well. so far i have the custom intake and greddy RS bov installed i will have all of this completed shortly and i will let you know the differance. I'm also custom fitting a Magniflow turbo back exahsut and upgrading the turbo and oil lines should be getting some nice power then I will post progress pics and power gains soon

[spike blue]

men that sounds awesome !!! Please let us know!!!

[otnielarencibia]

Keep us updated please....

I waiting for DG Motorsports about makeing a CF hood for our CX-7's Like they made for there concept car at SEMA, U know what I mean.

Im putting the gauge near the pillar on the driver side till the radio bezel comes out then i will be mounting the rest of my gauges in the second din slot

[hectik1]

Cool...I am putting my boost gauge somewhere factory looking.

Upping boost won't gain you much. Have you seen this:

Looks like all the power will come from a proper tune. Someone needs to crack this.(shocked)

hey can u post a larger pic of your cx-7, im gonna assume the pic u have is your car. Looks hot tho id like to see it blown up

[evo_mr2006]

Whats up everyone,

Some people wanted me to start a thread for my project for my cx-7. for some reason I'm haveing problems posting a threat so I'm posting it here for now. I have plans on seeing what we can get out of our cars, So far I have the front mount intercooler that Im going to be custom fitting, boost controller, boost gauge, greddy type rs BOV, magniflow turboback exhaust that I will be custom fitting and some other plans to come. This is going to be a lil slow start due to it being winter time and I don't have a garage to work in.

Please feel free to give me helpfull input as I'm new to the performance end of our crazy opsession.

Here are some start up pics that i took for mesurments
for the piping and size intercooler i can fit.

good Job post more pictures when you are done!!!

[VENAM1]

evo_mr2006, can't wait to see more pics / details on your modifications...

I have a dumb question for you though:

Is having a top-mount intercooler "upgrade" and getting a new front-mount intercooler redundant...?

Is it usually "one or the other" vs. both?

Im not sure what you mean if your thinking that im haveing the top mount plus the front mount thats not the case i'm getting rid of the top mount and going with a front mount

[VENAM1]

Yep, that's what I was wondering, if having both is overkill...

I've seen the TMIC for the CX-7 being sold but hadn't seen a FMIC for it yet (without custom work being done) so I wondered which is better?

Why did you decide to scrap the stock TMIC...?

Does the FMIC provide more HP gains?

[Maguyver]

yea id like to see the pics too, especialy of the BOV (im thinking of putting one in soon)

Ya the front mount intercooler makes more HP due to alot more cooler airflow being directed into the engine. From what I understand it adds ruffly 40-50hp
correct me if im wrong

[evo_mr2006]

I just took a few picts of the intake and BOV so you guys can see that part

very nice pics thanks

[spike blue]

nice job Evo

[VENAM1]

Yeah evo_mr2006, thanks for all the info and pics...

I also was wondering, in regards to your BOV, do aftermarket blow-valves perform better than the OEM ones, in terms of possibly "extending" the life of the turbo?

Does a high quality BOV "improve" / sustain the performance of the turbo? Is there a perceivable performance improvement? Or is just to get more turbo "sound" (as I have been told)?

Finally, how's that FMIC going...? ;)

[otnielarencibia]

Blow off valve's do not give any performance improvement. It is more for the sound than anything else. As far as longevity to the turbo....most likely since no air is hitting the turbo when not being used.

[Blake]

looks good, a blow off valve helps with compressor surge.

Thanks the bov just mainly helps relive pressure build up but performance wise nothing really as for the front mount intercooler im just in the pipe fitting stage due to me not haveing a grage to work in and its still winter but as soon as it gets warmer out things will pick up

[Quickie]

So you can run all atmosphere bov, i thought the cx-7 only could run resirculating vavles, like a dv. Do you get any codes? any problems running into a full atmosphere vavle?

[SuperStretch18]

looks good, a blow off valve helps with compressor surge.

If you vent to the atmosphere, it also throws off the MAF sensor and makes you run momentarily rich when it is purging. A recirculating valve is a better option for long term reliability, but even still, . Read this:

I had to go back to resirculating cause it was running really rich and it messed with my sensors

I think the 40-50hp should come with the extra boost, not just for the FMIC.
FMIC alone would get you 4 -15hp gain max.

EDIT: Have anybody installed a boost controller (http://en.wikipedia.org/wiki/Boost_controller) to your CX7 ?!?
I think something like Profec B-Spec2 Boost Controller (http://www.alamomotorsports.com/greddy/grprofecb.htm) would be nice and safe addition for around $300. (drive2)
Anyone? (first)

[cx-7_racer]

Just ordered my boost controller Friday but they are on back order.

manual controller huh! - so it would be like no feedback - just a "feeling" (ricer)

[evo_mr2006]

I installed the Turbo xs manual boostcontroller when i put in the boost gauge and there is deffently a differance but i dont dare turn the boost up to high i'm running with the front mount roughly 21psi.

[otnielarencibia]

How does 21psi feel? Don't you think thats a bit too much?

[evo_mr2006]

lol j/k im not that crazy to turn it that high i'm about 19.5-20 psi right now and it feels good great power for now

[AWmustang]

Brake torque this puppy to about 2200 RPM and it will knock you back in your seat like you wouldn't believe.

First time I did, it Knocked me back so got I bumped it into 2nd right away.

[HeavyH20]

Yep, with TCS off ;) Doing so will yield good mid 6 second 0-60 times.

Have you made it to the dyno yet? Also hows your gas mpg with fmic and extra boost? Anyway to check your AFR with the boost as high as it is?

Thnks,
MM1

[hectik1]

Bet you the turbo isn't even effiecient to 21 psi.

[evo_mr2006]

probably not that why im getting a bigger turbo and better set up

[evo_mr2006]

gas milage went down alot and i'm not sure what AFR is like i said i'm new to the engine moding so iI'm learning as i go

[dread]

setting a boost controller to 21 psi could be dangerous for your turbo and engine. I am surprised you are not getting boost cut from the ecu, because your turbo is out of its efficiency range at 21 psi. Be careful

[HeavyH20]

To quote Garrett:

Air/Fuel Ratio (AFR) tuning: Rich v. Lean, why lean makes more power but is more dangerous

When discussing engine tuning the 'Air/Fuel Ratio' (AFR) is one of the main topics. Proper AFR calibration is critical to performance and durability of the engine and it's components. The AFR defines the ratio of the amount of air consumed by the engine compared to the amount of fuel.

A 'Stoichiometric' AFR has the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines, the stoichiometric , A/F ratio is 14.7:1, which means 14.7 parts of air to one part of fuel. The stoichiometric AFR depends on fuel type-- for alcohol it is 6.4:1 and 14.5:1 for diesel.

So what is meant by a rich or lean AFR? A lower AFR number contains less air than the 14.7:1 stoichiometric AFR, therefore it is a richer mixture. Conversely, a higher AFR number contains more air and therefore it is a leaner mixture.

For Example:
15.0:1 = Lean
14.7:1 = Stoichiometric
13.0:1 = Rich

Leaner AFR results in higher temperatures as the mixture is combusted. Generally, normally-aspirated spark-ignition (SI) gasoline engines produce maximum power just slightly rich of stoichiometric. However, in practice it is kept between 12:1 and 13:1 in order to keep exhaust gas temperatures in check and to account for variances in fuel quality. This is a realistic full-load AFR on a normally-aspirated engine but can be dangerously lean with a highly-boosted engine.

So, by dialing in too much boost, you are creating more heat and possibility for knock. If it is severe enough, you can blow your engine.

[CRD]

Have anyone tested more boost with a wideband yet?

My cousin is selling me his profec b boost controller and he haves a portable wideband sensor/datalogger from innovative. I'm going to solder a new bung to the cx-7 and play with the boost a little bit , I will keep you guys posted, first I have to take the cx-7 to the dealer for the 3rd oil change and tunning, before I put the boost controller.

[1Sleepy93]

Trying to push more boost from our already overworked turbo probably won't net anything except lots of hot air.
