My mechanic laughed at the turbo when viewing the boost on his laptop via flashpro. I wasn't even a 1/4 throttle and it was about 8-10psi... We need a bigger turbo RDX family!! Maybe someone can get a group buy together for a turbo manufacturer to build one for our car?!?!

BigHatch

some may be due to the variable turbine inlet too... but still!

KenB350z

Yeah, would like that boost to come later in the power band.

KenB350z

These are the shoes.

That would be nice it would also help with gas mileage too

SinCity

Ken: I may have missed it...but how many miles are on your motor?

KenB350z

I have about 111k

protoRDX

1) isn't this how a variable flow turbo supposed to work?
2) who from manufacturers will possibly get involved in a custom turbo development with a possible market of max 50-70 enthusiasts?!
3) even if we get a bigger turbo, how do we fool the variable flow valve actuator? This thing is controlled by the ECU.

The variable flow is essential just a wastegate.

Tomtwtwtw

Seems if the proper tables are available for tuners, you can eliminate the variable flow element altogether and slap an externally gated turbo on there. IF

I like the instant boost I wish it would carry further through the rpm range that's my only complaint which is why I'm getting blouch performance turbo to put a bigger wheel on the compressor side of my factory setup. they led me to believe with the supporting fuel and exhaust mods it would be good for between 35-55 horses... the only thing im missing is cams and a fuel pump ( I was told nothing would fit when I was buying my list )

KenB350z

Yeah, I'm just trying to run mid 13's and I'm good. I currently own a bakery with my wife and the RDX is one of the delivery vehicles, so I don't want to do to much to it. Just mid 13's and I'm good.

KenB350z

I'm going to try and get a charge pipe made at Humble Performance.

guess some more pics are in order

KenB350z

Drove it from OKC to Tulsa

KenB350z

Here is a shot of the gas gauge.

dresx

13s should be doable. wrx guys with tdo4l-13t run mid to high 13s.

How much power do you expect to make?

KenB350z

Hard to say the Hp numbers, I'm hoping in the 300's.

protoRDX

WRX weighs 300 kgs less than RDX. + manual tranny

rdx 2008 SHawd with nav curb weight 3964 + m F.A. 178 = 2Tons + ...

damn I wish I could pull those numbers for driving around.

bluecarbonfiber

what was your average speed? those are great numbers for mpg!!

shivaswrath

that's insane!
And this is with a basic tune?

protoRDX

Guys, this is not insane. These are incorrect numbers due to bigger injectors. The ECU calculates avg fuel cons based on the stock injectors bandwidth.
If you check it manually you'll still get same old 20-22-23 mpgs.

shivaswrath

AHH!!! Yes, that makes sense. Stupid ECU!

oh ok now I feel better... jeez that's what mine shows too.

bluecarbonfiber

hmmm.. well then if thats the case.. i am curious on if the tank was filled prior cause if i do 167 miles with a 50/50 hwy/street driving i would be at or below a half a tank..

dresx

All true. He should, theoretically, make more power. His torque should be through the roof at launch. There are plenty of high 13s chevy trucks and suvs with around 300 HP. This won't be easy to do, but a reasonable goal I think. I'm interested to see how it plays out.

KenB350z

I had a full tank before leaving Oklahoma City and that was the end result. I'm sure it will be another story after it's tuned.

bluecarbonfiber

thats pretty good then.. whats your avg speed? 65 70?

KenB350z

I was traveling 75-80, the average on the tech was 50. probably run a little lean, not sure.

bluecarbonfiber

im sure you are pretty lean.. you still havent gunned it yet i am guessing till you get your tune..

your next fill up you should do the actual calculation just to see how close the mpg matches.. im sure its closer to 30.. specially if you did a 150 miles in a quarter of a tank

KenB350z

What an awesome day, took the RDX in for a recheck of the valve and got to take the mechanic's 600hp Tundra!

KenB350z

I'll do that next week.

SinCity

So the engine is still strong at 111k miles. That is awesome.

I get about 340 out of a tank if I stay out of it but its so hard to keep out of boost when it just screams. I think im going to get a take home car from work so I can get the turbo done. see what ill get out of that. what P# is the in tank pump and was that a pita to install?

Tomtwtwtw

I've had mine still read over 3/4 after 150+ miles...gauge goes down slower at first. My first 1/4 might be 150 but my last 1/4 could be under 100. If I recall right on that tank I got a hair over 400 miles before filling up, between 24 and 25 mpg. Keep in mind I'm FWD...even if it's not the indicated 30+, if you can average 25 on a full tank with AWD it's still quite an accomplishment.

TheNewAcura

I think it's safe to say everyone here is dying for a tuned dyno run

KenB350z

Give me till tomorrow for updates on the pump, the DW200 looks a bit taller then OEM. Our pump looks more like the DW65c. I'll post as soon as I get back from there.

KenB350z

Waiting for them to open.
