i've been doing some testing on many different K-series engine setup here at my shop. I was wondering what are you K20A2 "US RSX-S" guys are putting down... We just completed a k20A2 swap in an EK and tuning with one of my headers and a Hondata K-pro and the numbers are looking almost unreal making as much as some K20A engines.. ill post up some pictures and dyno soon as we finishing tuning..

 

there's not much difference in the 2 engines, without a full cam angle tune on a K20A it would be easy to get equal HP out of a K20A2 if tuned properly. I could prolly pick up an additional 5 or more whp with proper tuning on my K20A, more in the midrange for sure...but I'm not too concerned w/ peak power, average is what it's all about

Danny first of all, thanks for the great header.

The rsx type s in 100% stock gets an average of 170 whp (165-175)

At clubrsx.com there are a little of dynos... 200whp with k-pro I/H/E and a really good tune.

The toda head package with the toda reflash gives around 230whp.

What I want to know is what you consider UNREAL NUMBERS?

Better start mandrel benting these headers to increase production

Im starting to realize myself that there is barely any difference from the K20A2 and K20A engine - the type R transmission witch is shorter...

lets just say we are making just as much as some Type R motors already...and we are still having problems with fuel pressure droping.. ill get some pictures up today of the car we have and a possible vedio clip of it on dyno. and final dyno result later this week

 

I know exactly what you mean w/ the FP...anyway good numbers...looks like I need to go make more power

 

Keep us updated Danny.

Bump for dyno #'s

 

Are you talking about the 214.5whp that was in the thread you used to show us the prototype you were making?

No.. They dynoed the car again with hondata #4 flash. The reason why they are not posting the dyno is because they are not done. The results are amazing, to me at least.

 

alright guys... 3 days of dyno tuning we beat this motor to death to see how much we can squeeze out of it..

Here is a picture of the test subject Ek with K20A2. Modifications include DTR 4-2-1 stainless header, custom 3 inch exhuast, Hondata K-pro, custom Intake, and stock modified Intake manifold.




Our first day of tunning went pretty smooth. Included with the Hondata K-pro package is many base map program files. The base map we used for our motor was K20A type R program with intake exhuast header. At the end our day we finished with 212Hp@155lb of torque. We notice a big drop in Top end horsepower and we assumed it was caused by fuel pressure drop. Which still gave us hope that there was a possibility of making more power.

The next day we upgraded our fuel pump and made some adjustments to the regulator return line and our fuel drop was fix. Excited we threw the car back on the dyno and to our discuss the motor didn't make any more power! We check our lambda and the A/F ratio was fine. Then it dawned on us that there was a possiblity that the K20A2 Cam profile may be maxed out and we can't possibly any more power, but wait Hondata K-pro give us the option to tune our cam degree at any RPM. With this in mind we took away 2 degree of cam timing between 7600 rpm and 8000 rpm and we gained! No peak power but definately more top end. Day 2 concluded with no peak gain but some gain.

Day 3 we wanted more power, but with this cam maxed out what do we do. We were going to save this manifold we've been working on for a Type R motor we started to polised it after we ported it but we had to test this manifold to see if we can make some more top end. From our pass experience many common manifold with port work like this yeild about 8-12 hp on b-series motor depending on cam lift. So we expected about 8 Hp gain. After 20 mins to swap manifold out its was back on the dyno.. we warmed the motor up and ran 3 consecutive pass and again we were let down again.. It got some gain but not what we expected. We only gained about 4 Hp top end. This basically put the nail on the coffin "we need a bigger cam!"





here is the finished result.. we expected to push this a little more but 216hp @157lb This motor is a K20A2 Torque monster!

157 pounds of torque at around 5k rpm! Jesus. Good stuff.

check this out John

we threw the car back on the dyno again! 20 more passes... this time we played with the Iginition timing..... here you go!



this was with exhuast piping on

 

218whp/162 very impressive for a k20a2

 

ok i have now decided to stop throwing away money on b-series motors

 

holy ****. thats ****** insane, 162ftlbs. im lovin my k already and it dont even run. you guys going to cmi or fontana with that thing?

 

and is the USDM type-S motor, is that correct?

Yes.

 

It makes more torque than my turbo sohc

Good job

 

awesome numbers

 

Congrads Danny, AWESOME #'s !

 

Nice

 

awesome numbers! lets get this forum rolling like some of the other H-T forums!

 

I can't wait to see the results of when more companies release cams for the K!
