Any insiders that knows about RTR ITR specs and tech? Like:
I only know that they have stock airbox with drop-in filter and VTEC cross-over at 4100rpm


But what about:
(logical estimates are welcomed)

Horsepower: whp and crank
Torque
Redline RPM
0-60
1320
Curb Weight
g's
Slalom
Engine mods
Header
Exaust system...or non?
Compression ratio
Gear Ratio
Chasis work
Shock
Springs
or Adjustalbe Coilcover
Ride height
Brake Rotor
Brake Pads

.....etc

a lot of the stuff is already on their webpage...like weight, brakes etc..

 

If the 4100rpm cross-over is true...then there must be more stories in the tuning of their engine...Cams? Pistons? lubes...etc
Or else how is it possible to benefit VTEC at such a low x-over? After all...didn't they spend nearly $50,000 in modification for each car?...if I remember correctly on the old C/D article.

If i remember correctly, the Real Time ITRs, are one of the more "stock-like" cars in the SVWC

Roger Foo's civic only costed what, 12k? or was it 17 i forgot.

 

I'm not sure about the exact specs of Real Time ITR's, but they like all World Challenge Cars have to comply with the strictly enforced SCCA Pro Racing Regulations. The Rules have been changing every year.

I think the ITR's are allowed to run non-stock ECU's, so that will explain the lower VTEC cross-over point like the Mugen or Spoon ECU's. For the complete rulebook & tech specs, go here:

Yeah Roger Foo's car was estimated at about 12k of parts, it is a pretty basic build up as well.

 

real time runs mugen N1 ecu's. each car runs a different header from what i saw. as far as the internals, they are stock. and they run the nsx airboxes and intake tubes, not the ITR. kinda weird since there are so many ridges in the tube that can impede the airflow.

From an article on one of the realtime ITRs in SCC from what i can recall from the top of my head, it stated that the only mods it was running was an factory NSX intake piping and airbox, running on stock cams and internals, cam gears, Mugen ECU, mugen headers and a borla race muffler, for suspension they were running some stiff *** eibach springs and a custom rear stabalizer bar that was 26 mm i believe. thats all i can remember right now. pretty much just bolt on power. They do have certain regulations and restrictions that they need to adhere to. All the mods are pretty simple. No drastic super tuning on these cars..

 

I think I remember reading they pull over a G in the corners!

They also have metal bushings in the suspension.

 

Yes, they run a NSX airbox through a custom headlight intake tube. They are using a Mugen N1 ecu. They make there own headers (Gemini) along with help from one of the leading manufacturs of Harley Davidson headers. They also are using lighter pistons ... and I believe lighter connecting rods made by AEM.

 

I asked Dwight, the Realtime guy, about HP. He said their ITR are around 214 at crank. I think he is very conservative about the number while other camp were saying that their B16A were making way over 250HP at crank.

 

I've seen them in real life and they are FAST and LOUD.
They seem to go about twice as fast as a regular stock ITR.
I cant explain it but they definately have something going on.
Anyone know what one would pull in the 1/4?

 

i talked with the real time guys up a sears point this year and trust me, there is more going on undernieth the hood than has been told, they assured me. They have also done a lot in the way of stiffining up the chasis.. The cars are just awesome to watch in person. If you can make it to a race I highly recomend it.

here are some pics from Laguna Seca, the ITR's are in there somewhere.. http://www.aktusa.com/LagunaSeca092001

Yeah. I saw RTR in person in Lime Rock, hence my question. Because 208 BHP won't cut it, they seem that they can pull at least a mid 13s in 1/4 miles. Not that 1/4 mile time matters too much, but if at such a setup of power performance and a reliable run of 30+ eudurance laps. Their setup should worth our attention. Such as the NSX intake box, had anyone try out this trick?
Also They are extremly loud, so loud that it sounds painful and unbearable to human ears...even the loudest, muffler shattering riceboys's rockets seems like a baby comparing to their dB. But what surprises me the most is, the underdog Mazda Protege. That car pull on the ITRs almost every lap on the straiaways, and all the BMWs as well. But it always have problems half way through the race.

 

If you're not cheating, you're losing.

 

Don't underestimate those mazda's.
This is the first year that they have been competing and they are definately working out the bugs. Mazda is fully behind the team whereas acura only moderately backs up Peter Cunningham and the realtime boys.
Also It seems like various new rules being introduced this year are aimed directly at slowing up the R's.

 

isn't it true that for every race you win....you get "awarded" winning weight? This is so that your "advantage" over other competitors diminish so it acts as a leveller among the competitive field?

I seem to recall watching the Touring races last year and they said that the RTR Integras were weighed down so much that the race steward further banned any more weight added because it was threatening to break through the floor of the car!....... they then showed a clip of where the passenger seat use to be and showed a moderate stack of metal plates added.

If that is the case, and the RTR cars are indeed weighed down to the max allowed by safety regulations....it juss shows that the RTR team is extremely well sorted despite the lukewarm backing from Acura....

The realtime cars also have a restrictor in their throttle bodies because they were deemed too fast and you couldn't add anymore weight to them). Who cares if the Mazda pulls in the straights--their cornering speed isn't as high, and that's where it's at.
