all motor - jdm k20a with I/H/E & mugen headgasket (.4 increase in CR) is what is planned for the set-uphybrid racing said:Is this an all motor setup? Turbo? Supercharger? They all like the cams set different.
You are looking at 1.5-2hrs max if you know what you are doing.RC000E said:that is alot of dyno time though to get it right.
Cam angle and ignition are yielding the most gains. The RSX runs very rich on the top end so leaning it out to 13.2:1 A/F ratio will help with the gains. The RSX is programmed to run on shitty gas despite the recommended premium fuel. So if you are serious about performance, you will run either 91 or 93 all the time so that is one of the basics for Hondata's reflashes/calibrations...they are able to significantly advance the ignition. I would assume the RSX stock ecu uses very limited cam angles because of emissions. By retarding cam angles, Honda can get better gas mileage which is appealing to large numbers of people.RC000E said:is there any one thing that seems to be the target area of improvement? Are the fuel maps really fat for safety and doing a slight lean is yielding all this power?
Hondata has both a reflash and a k-pro calibration for the K20A. I have seen numerous dynos of K20A2's with ITR cams and IM putting down 210-220whp. A real K20A will land slightly higher because the only noted difference is a half point compression increase. Toda's N2 cams will perform better than the ITR cams.RC000E said:Also, I am seeing alot of dyno numbers from the A2's, such as on your site Toda. I am wondering though, what the results are with the JDM K20A? Also, Hondata as I recall, doesn't have any base tune maps for the k20A. I would assume that using a K20A2 map for the K20A surely wouldnt be the best idea given the fact the K20A has a 20hp difference. Any light on this?
