Someone hurry up and upgrade your turbos. I cant wait to see a 400 hp RDX on the site.

SinCity

400 HP? We don't even know the max HP/TQ the transimission can withstand.

RDX REX

ya upgraded turbos won't be a reality until all the other performance aspects are looked into to upgrade, for now the best bet is the Hondata, CPE cold air, and church turbo back exhaust

Is anyone out there willing or really that crazy to mod their brand new RDX to 400hp? That would be a sight for sore eyes...

This thread fails to deliver.... :P

It's a bit of a stretch, but I bet you could get to 400 at the crank if you did all the possible mods today.

1: reprogram would be needed at some point
2: Church exhaust

and then do what other people do with turbos:

3: alcohol injection

The alcohol injection would effectively keep the intake cool, and raise the octane a large enough amount to increase the timing a lot. Probably a 40 horsepower boost on top of everything else. Maybe only 350 horsepower...soo.....

the big hit

4: nitrous kit

If you wanted to try it out 'safely', use a progessive kit with the nitrous and it wouldn't 'hit' toooo hard and would be a blast. I bet a 75 horsepower kit would be phenomenal.

The whole trick here would be the programming to help keep it safe.

Larger trim turbo + larger IC + ECU reprogram (hondata/chromepro/neptune/) = will net easyly around mid 350hp safely.

The turbo upgrade is going to be a long time coming because of the variable flow stuff.

Hey vrflyer!!! U mentioned the Neptune ECU... I have searched this forum to see if the Neptune ECU has been installed or work in an 07 RDX however u are the only one who has mentioned it... I have several converted to OBD1 Neptune (board) ECUs in my other Hondas... Is the RDX capable of being converted from OBDII to OBD1 for an programmable OBD1 ECU? I have found a few harness adapters however no OBD1 EMS. I am going to send Neptune an email asking... Do you know what gains were achieved from the Hondata?
Thanks Man

Completely different type of ecu. Only hondata flashpro is available.

MrBlue

Bummer!!! I really like the ability to fine tune and change other parameters with the Neptune EMS... Thanks

Slow98teg

Well flashpro allows everything to be adjusted as well.

MrBlue

Cool... I wasnt aware the Flashpro had those capabilities... So i can plug in my laptop and set the parameters to have throttled (4000 rpms or so) boosted (5psi or so) launches like Neptune? not that i would on my RDX... I do on my race lude.

Slow98teg

Honestly i don't know about that. It was just released for the rdx about a month ago. Haven't ordered one yet. Not really sure if there would be anything to help with launching.

MrBlue

Ok and Cool... I will check out the Hondata site and find out... Thanks Again

MrBlue

Yea I know it was an old thread however it was the only one that had the word "Neptune" when i did the advance search...
JR from Neptune said His "Other Company" is working on an EMS for the RDX Platform however couldn't give me a time when it would be available... I guess i will check into the flash pro.
BTW... were U aware that the stock ECU will build boost if you press on the brake and gas from a stop? its slow to build boost and a weak launch however does work. I am curios now how and if it works with the flash pro.
