I'm getting the Hondata Reflash this week (I hope)!

In the near future, I'm hoping to do either an intake or exhaust, but not both since research from this site and Hondata seems to indicate that the fuel mixture will run too lean with all 3 mods (Hondata, Intake, Exhaust)

Any input on which upgrade I should get, and why??

Thanks!

 

your better off buying a used flashpro then paying for the reflash. i see your from new jersey i would be willing to meet in say the philly area and give you a ride so you could see how far you want to go with your rdx.

 

That would be great!

Can you run any used FlashPro or does it have to be a specific the specific RDX part# FP-RDX-US ?

 

The 1st cat right after the turbo is the biggest restriction of power for the RDX. You can almost just do the downpipe to get similar gains as doing Hondata. Add Hondata on top of that and you have a pretty good bang for the buck mods.

 

Just wish Wrench was closer to Florida. Wouldn't mind downpipe installation assistance for some beers and Pizza and wings Alas, I still only have the intake and Flashpro on the normal tune that came with the Flashpro. Grrrr

 

needs to be specific for the year and make.

 

try to hook up with "Mike" he's a florida guy also drives a red one. has a downpipe and some other mods rims springs rsb? iirc

 

Flashpro only I picked up a decent amount of power and fuel economy. Added downpipe and exhaust and made almost 260 to the tires. Don't waste money on a reflash if more mods are in your future.

Take the downpipe out the top. Remove the top mount, top head shield, a few brackets, and remove the dog bone on the bottom. With the valve cover removed and engine tilted forward should have enough room to get the downpipe out with just a little fiddling. Going back in is much easier.

 

I have the 2011 FWD version of the RDX. The one that some people have had drive shaft problems with, but knock on wood, nothing so far. It is still the second car, so I have put only 10K miles on it in 28 months of ownership. The downpipe seems like a self doable upgrade, but when you indicate the engine needs to be tilted forward to remove the old pipe, I have no idea what that entails. Doesn't an engine weigh several hundreds of pounds, how in the world would I tilt an engine forward, or sideways, or anything? Sorry, not a mechanic, just like to tinker with basic stuff. Thanks Wrench and Gearhead98 for any advice.

 

its better to do the intake, RV-6 down pipe, Blouch upgraded turbo, and ETS intercooler all at the same time. also injectors and flashpro. that way your not taking things apart and puting them back together 2-3-4 times.

 

Hey Wrench I'm new to the RDX, have had mine for two months, can you give me more info on the Blouch turbo upgrade?

 

Sorry- I have the 2007 RDX.

I ended up getting the Flash Pro since there are future mods I plan on doing.

Now I'm debating on what order to do the following upgrades:
-ATLP exhuast
-ETS intercooler
-EBC brakes/rotors and steel brake lines
-BC Racing coilovers

Any thoughts or suggestions??

 

ATLP is A waist of $$$

1. how much power do you want to make?
2. pm me for a phone # lets have a discussion.

 

in what aspect do you think its a waste a money? I had there exhaust on my rdx and loved the quality and sound of it.. if I remember correctly marcus has stated he could do the exhaust in a 3inch for more power but it would be a 1 off thing and you would need to contact him directly for info. if youre talking about the aspect that it only adds a few more hp then I can kinda see your point the exhaust on the rdx really isn't the bottle neck if youre looking for more hp quickly.. its the downpipe that would need to be replaced before you see real changes..

not trying to start anything just putting it out there that Atlp makes quality parts just not sure where youre coming from on your statement

 

its my OPINION (not yelling) that for the money ($1,200.00+shipping) they were originally asking for what is essentially a cat back you could, get flashpro, injectors, and a tune, and make 30-50 WHP.

for my exhaust (down pipe back) it was 1 cheaper($700.00) made more power 15-20 WHP and i didn't do anything but swipe my discover. nice to not get dirty for once.


the stock cat back is quieter on the highway and still sounds great when you bury the throttle. untill your looking for 10/10ths its not necessary to address this portion of the vehicle.

 

Was your turbo upgrade off the shelf, or custom?

 

Subscribed!!!

 

like half and half. so i can supply the core if your willing to give a deposit which would be refunded once you send me your good core. good meaning it needs to not have worn actuators.
also grind on the turbine inlet and try to shape the passage ways some to reduce hot spots and turbulence. seems to work well.
that said intake, flash pro, along with injectors, down pipe, and the turbo will get you to just over 300 wheel horsepower on good old 93 with an otherwise stock fuel system.

i am recommending that you get a new exhaust manifold gasket and have that installed all at the same time to prevent leaks.

i also did some minor shaping of an exhaust manifold. port matching and rounding off corners blending and opening up of the turbine flange area. but i just swapped it on last week and it seems to like the changes a lot.

 

Wrench.....so the Flash Pro is able to clear or prevent the check light that will occur from all the mods?

 

yes

 

As an owner of the ATLP system, I agree with Wrench about it being a lower priority upgrade. I am quite happy with mine, especially since I added a resonator. A custom 2.5" exhaust would have been better.

The real 'limitation' that prevents making much more power is simply the ability of the turbo to flow no more than the amount of air needed to support 270 or so horsepower in this 2.3 engine. Google how to read a compressor map, that can shed light on exactly why this is the case. It took me ages to figure out!

If you want 10 or so horsepower and really want to pinch pennies, you can get just a CP-E intake. I'll make the car louder and run a bit rougher too.

Anything else, start with getting a Flashpro.

 

Wrench is it OK if I give u my # been trying to figure out what to do with my rdx 11 . All I want is to make more power of the line and boost hp. For a reasonable price

 

Hi there TheWrench116 sounds like you know alot about these RDX's,And what make them go.I understand that i am new here, but just wondering if i need some help with some answers to some question you can help me. I have a 2007 RDX turbo What type of HP, do you think it has with just a 3" CAI and a 3 " downpipe midpipe Stainless steel no cats and the rest of exhaust is stock.i am planning on buying a flashpro would like to find a good used one if possible,and if i can use the regular tune that it comes with, with my setup with no problemsThank you

 

If you just slap a big CAI and catless exhaust on there without a custom tune, you'll be leaving a lot of power on the table. The car may also not run as smoothly as you'd like without a custom tune, but let's assume for now that it does. Maybe you get 30 hp from the basic reflash and bolt-ons, but a custom tune (and likely fuel injectors) can net you at least another 30 - maybe more depending on your specific situation (fuel, climate, etc). Every car is different and your fuel quality can play a significant role.

 

I use 93 octane right now so with what i have what type of HP numbers, do i have about with what i have done now not including a tune runs pretty smooth right now. thank you

 

i can assure you that there is quite a bit of power left on the table and possibly mileage as well. Ask around or post enough so you can pm people and I'll give you my number as I'm rarely on anymore.
If I had to guess your around 185-200 whp 225-250 wtq for reference tuned rdx is seeing 260whp and 350+ tq sooo call me!

 

ok sounds good maybe we can meet some time in the near future so i can get this rdx of mine to get up and go thanks again by the way i don't live to far i am in N.J.

 

just checking in. looks like ill be going fullrace in july :P so big numbers here i come!!!

 

After you get the full-Race in, your 4th gear pulls on the highway will cause a blurring effect.

 

How about them #s?

 

give me more time my head is still at the machine shop ...
