has anyone upgraded anything? bov? IC? piping? cats? anything just wanted to know...

Check out the RDX Forum at http://www.vtec.net/ Somebody is putting together a $5k performance package in southern CA, but they are talking about trying to license throughout country, once they get the right mix of tweaks.

noone?

Cruise over to TOV and see the threads on the project RDX they are working on, something like boosting to hp and tq by 40 each. They are running into the limits of the ECU fuel mapping program. It is very interesting.

Well I know TOV is Temple of VTEC which is found at http://www.vtec.net/
...
I don't suppose anyone else could get us any closer to a link to the forum mentioned.

Drabert

do you have a link to that write up? everytime i go to the temple of vtec sight, i cant seem to find anything... found a few videos on youtube though... a link would be helpful

thanks

No links allowed to competing websites.....

batman

TOV is a competing site???

XIS

Well, you can link it here and then open a separate window when it is clicked so that this site stays open too, or you can deny the link and then people will just type the domain in the address bar instead and click OFF this site.

Cooperation builds the forums. It should not be looked at as competition.

Drabert

ok how about some guides on how to get to that section of the site? i searched around for about half an hour last night and couldnt come across anything but thier project si..

TOV is no competition

Here is a link. Things are hard to find on TOV. This website is way more friendly, and I spend way more time here...TOV is more Honda based than Acura based.

PS I do hope sasair was kidding....

By the way, here is an interesting reply on the string above about the durability of the K23 engine used by the RDX. All I have to say is WOW!

http://www.vtec.net/forums/one-messa...ge%5fid=655445

"I'm not too worried about engine durability at present (tranny durability? we'll have to watch it for 10k miles of hard use and do an analysis of the fluid). Here's why.

1) Past experience - We've tuned a number of stock block k20/k24 engines that have been turbocharged. The weakest of these engines is arguably the K20A3 from the EP3 Si, the strongest, the K24A2 from the TSX. When I talk about weakness, I primarily look at rod strength (the K20A3 rods are tiny), cylinder wall strength and piston strength. Honda cranks are bulletproof to over 800 hp so they don't even enter into consideration. Of all the aftermarket turbocharged K-motors we've dyno'd, none of them have any trouble supporting 250+ lbs-ft of torque to the wheels for long periods of time. In fact, we've found that the limits of a completely stock block K20A2 (RSX-S) block tends to be reached between 300 to 350 lbs-ft of torque. The K24 seems a bit stronger than that. The primary failure mode for engines pushed beyond this point tend to be piston failure (cast pistons, small ring lands for N/A use), ring failure (probably due to overheating of the ring area or overexpansion of the piston) or headgasket.

2) Design of the new engine. Honda designed the K23A to handle sustained output in excess of 260 lbs-ft. From past experience, that would indicate the ability to support far more torque. Second, the bores on the new engine are substantially thicker than the other K-series designs out there. Third, the piston design is far better suited to FI, with the rings moved down to protect them, and more durable materials used for the piston. Finally, a much lower compression ratio (remember, the other turbocharged engines I discussed were running 10-11:1 compression ratios). I don't think that 400+ lbs-ft of torque will be _any_ problem on this engine. And it will probably support a lot more.

3) We're not pushing that hard. I'm hoping to pick up 50 lbs-ft of torque at peak. A 20% overcapacity is well within design specs for any automanufacturer, let alone Honda.


SC

p.s. - certainly any iron block turbo engine is going to have better long term durability (iron is tougher than aluminum), but at the power levels most people look at, aluminum isn't an issue."

Any other RDX forum is considered a competing site. I don't make the rules, I just enforce them....

Chas2

I guess I should read the rules first. Had no idea.

SolidState

For a open forum it just doesn't seem so open anymore. You might as well start blocking people or links to acurazine web site.

PANG_CO

I've installed a Air intake kit on mine. Makes it a bit more fun to drive and better throttle response.

Working on the Cat delete next with new downpipe, etc.

RDX REX

What kit is it? I didn't know they had any out yet

phoju

nice... plan on doing anything else?

RENN

Hey Pang,
Where did you get the air intake kit from??

swift22

well if you can't link competing sites with useful info then i would think acurazine should push the envelope....work with Ronjon and performance gearheads on this forum to do an RDX and put it in shows advertising the forum

neo1738

who makes aftermarket performance parts for the rdx? havent found any as of yet really, although i havent really looked that hard

PANG_CO

Sorry, I don't check this site frequently..

I produced this intake kit for myself just for fun and better throttle reponse and have sold a few to others that have been interested.

I'll be producing High flow downpipes and mid-pipes here shortly. Once my machinist gets back to me with the flanges. Will post before and after dynocharts as they come.

Here are pics. (Mods let me know if you need me to remove, not trying to advertise).

DNPhotography

^^ interesting. i would be very interested in purchasing one of your intake systems. oh and your engine could use alittle cleaning

i would also like to be updated about the down and mid pipes.

chyllintsx

id take one too... do u have dynos on the power gain?

porsherules911

I've also been looking to put an intake into my car so what size diameter fitting works and what did you have to remove to fit the filter in there?

phoju

niceeeeeeeeeeee..!!! lmk about those pipes.. i wouldn't mind throwing those bad boys on...

DNPhotography

PANG_CO so no deals on the intake???
