Default Mugen RSX ?'s

was wondering how quick it is...etc...as i saw it on one of the ITR EXPO video's.

and could someone point me to a website that shows the specs on it...

was just interested in seeing what mugen has done to make a 2800lb car fast...

thanks, chet

Well, lets see.
Bob Endicott told me (an awesome guy btw - talked with him for more than an hour on sunday) that that car has the following done:

Complete custom Mugen built JDM DC5R spec K series motor (he estimated ~250 hp) and after seeing it in person, I believe him - that thing is damn fast.
Fully customized suspension - including REVISED SUSPENSION GEOMETRY (because the stock DC-5 setup is awful)
Mugen reprogrammed ecu w/ digital dash display.
Stoptech 4 piston brake system
Moton Coil over Suspension w/ external resevoirs
Gutted Interior
Role cage
17" bling Mugen wheels
Custom Mugen exhaust - 2.5" stainless - no cat - sounds awesome in person
shaved Toyo Proxes T1s
Mugen Intake system
and probably lots of other goodies I forgot

- it looks to be a very fast race car - did look kindof twitchy - they're still tuning the suspension (struts on a FWD car SUCK - I don't care what anybody says)

Nearly every part on the car is a custom built piece. Very trick.

That's interesting, cause the Realtime DC2 R's are not all that different from most street driven ITR's...
I guess it just goes to show that if you start with a great platform, you don't need to change much... (DC2 R oWnZ )

I talked to the Mugen guys and found out some interesting things

Anyways, back to the car. I took some pix of the reworked suspension.

yshi - who thinks the RSX l00x g00t only as a race car

Whatever, why do you think that Realtime is the only DC2R team that has had significant success in World Challenge for the last 4-5 years? It's because they've put a lot of development into the chassis, suspension, and engine to get the last bit of speed (and they have excellent drivers). If you look closely at Realtime's R's there are a lot of subtle changes like spherical suspension bushings, a huge rear sway bar that runs through the spare tire well, and of course the requisite Moton shocks and other standard World Challenge bling. To say that the DC2R's are "closer" to street driven R's than the DC5 is to maybe street JDM DC5R's is wrong. Neither of those cars are close to street and both of them have a lot of modification to the basic platform. In your defense tho, the RSX is allowed cams in its VTS where the ITR is not.

Here's a little relativity for you: at Sebring the top finishing R was 15th driven by Peter Cunningham himself. The lone RSX driven by Kleinubing finished 2nd, and his fast lap was almost 4 seconds faster than PD's fastest lap.

With that said, the DC5 does have the benefit of not being as restricted as the DC2 is yet. The same way that the BMW E46 2.5 motor (the M52) is not inlet restricted the way the BMW E36 2.5L is (the result of this is that Bill Auberlen annihilated the entire field with his trick M52 powered 325).

I'm not trying to say that the DC5 is infinitely superior to the DC2 or anything, hell I own a DC2. I'm just tired of everyone stroking themselves and their egos by bashing the DC5 because they own a DC2. The DC2 has better suspension geometry for sure but thats about it. Why don't we just let the RSX build its own legacy and enjoy the legacy of the ITR without bashing either.

YOu can go on the SCCA/Speed world-challenge site and see what they are allowed as far as mods to the car for each make/model. The engine package is usually pretty detailed of what they can and can't do. I'm sure most of the speed these guys pick up is getting used to the car and tweaking the suspension setup. The output of the engines is usually governed very close by SCCA. I haven't checked out what the RSX's are allowed but for the Si's they specified cams, what IM, TB size, what porting is allowed and so forth. Like I said pretty detailed and I think they actually have a hp number that it can't exceed too.

Edit: for the Si's it says they can use the 1.8 GSR package if they are a certain weight. I think that's what Taz started running later last year. Sorry for the OT i just thought it was interesting they let the Si's use the 1.8 block.

i think someone clocked it at some 1:04 laps? That's pretty quick at beaverun...and others said he wasn't pushing it to the limit.

1:04 lap times - That's about a 90mph average.

They had the track all monday and tuesday, I wonder what their lap times were like after more testing and tuning.

Endicott said that Sat. (at the expo) was the 1st time the car was on a track, so it wasn't being pushed hard and little kinks were being worked out (e.g. it was running too cold on Sat, which explained the radiator being partially covered w/ cardboard on Sun). I don't think King's team would divulge everything about the car, but Edicott did say the compression on that circuit is limited to 12.5 and that the car was probably putting out 250 crank hp. I forget what the weight was, somewhere around 2300 I think. I would like to see the times they got on Monday and Tuesday as well.

Umm let's see - the King Motorsports RSX has completely revised suspension geometry (ie different pickup points, etc) - FRONT AND REAR... Realtime DC2 = stock suspesion geometry. Now I'm no expert, but if you have to re-engineer a car's suspension to make it competitive, that means that it wasn't designed correctly in the first place. Endicott said that as soon as you lower the stock DC5 chassis, all sort of strange things happen to the wheel geometry (ie toe in/out changes, etc). If you lower the DC2, you pickup a little negative camber (usually a good thing).

He also explained that the placement of the steering rack is not exactly ideal - I'm not 100% sure what he meant, but I believe that it is related to the tie rods, and their attachment points on the lower suspension arms. This was also altered on the RSX race car.

I'm not trying to rain on the DC-5's parade, but I think that honda screwed up a good thing by getting rid of the double wishbone configuration...

and i agree with that 100% ....double wish bone is a vital peice on a FWD car ...dont nobody start up with this crap about how Porsche , and BMW use front struts ....because they are RWD , and if you notice their drive wheels DO have a DW suspension ....

on kingmotorsports.com there is nothing about the Mugen ITR DC5 that went to the ITR Expo this year...anywhere that might have it?

Agreed, Honda did screw up a good thing. The switch to struts comes off as near hypocrisy from a company that has touted the superiority of double-wishbones from as long as many of us have been alive. Hopefully there is hope over the horizon...

From the Honda rumor mill...Honda usually goes through two generations with one basic chassis platform (suspension, motor mounts, etc.). So the EG/EK/DC were built on the same platform, the 94-97 and 98-01 Accord were one basic platform, etc. Honda typically does not make any huge architecture changes to the platform during those 2 generations. So the plan was to stay with the struts for two generations (Civic and RSX).

Hamever according to some Honda engineers I've talked to at more than one race, the overwhelming negative reaction to the struts has prompted Honda to totally redesign the global compact platform one generation early. So supposedly the double wishbones will return in 2006 or so.

it sure as hell better ....i think i can live with a lower ride height ...less wheel travel ...and a less smoother ride ....to accomidate for the double wishbone suspension

I'm wondering that too. I would think they wouldn't have started over with a new car, I don't think they would have the time. I would assume they fixed the damage. That's gotta suck. First practice day of the 1st race of the season and the car gets nailed. I bet that cost major $$$ to fix.
