To get HP multiply by 1.3410


Car belongs to Z from Australia.
Here's the car


The car is a k20a EG with DTR fab header using a 4-2-1 header (thanks Danny! ).

The lower line of course is the stock ecu.

Look at the midrange gain with the MUGEN ECU

In this dyno the upper line is the Mugen ECU




then two weeks later,

new dyno in with hondata K-pro tuned+3 inch exhaust + 104 octane fuel

the blue line is k pro vs the mugen ECU dyno




On average I have read that has Dyno Dymanics 27% driveline loss. That really doesn't matter though because reference there are dynos of cars on the same dyno.

For reference, cars that have used the same dyno (actual facility/shop)

Just one more note

The reason why we see such performance increase from RSXs with k20a VS Civics with k20a is mainly because of the header design. In the rsx the header geometry is restrictive and doesn;t allow the car to perform to its full potential.


this is the TODA header for k20a (USDM RSX type S )



and this is the DTRfab header 4-2-1 this car is using



I guess lessons learned from B series headers payed off

 

DTR header is looking good. SO how much of a power gain would you get from having the exact same motor and mods in an DC5 and then swapping it to a Civic?

 

I honestly do not know. My guess is around 20whp because there are 2-3 k20a eg that only with header and k pro are dynojetting around 220whp and I have seen stock RSX k20a dynojetting 180 whp on average without k pro and 200 with it. Tuning can take you a long way though so I am not sure.


Here's a video of the dynorun

Thats not bad numbers around 203whp

it more, the dyno has around 27% loss

 

sick car, makes me wanna be a k20 in an eg or ek even more

Do it!

Hopefully in a few years I will have a K20 CRX

I know you guys hate to use the calculator, but if you look at the numbers... this car is gaining almost 40whp with header, k pro , intake and exhaust.. He is using 106 octrane though but still that is a shitload of power. In dynojet terms roughly, he is basically going from 180-220. That is one nice jump

 

nice.

so is the DTR Fab header for sale to the public or is it a custom thing?

 

1/4 times?

The person who owns the car is in australia and that is his first drag racing experience... On full interior, power this power that, around 2200 lbs he pulled a 12.9 with 1.8 sec... I forgot the trap speed...

Also he has the full-race traction bar. The 12.9 was actually with the mugen ECU because in australia Hondata K pro tuning is not like here and the car was not ruunning very good with. We are trying to remotelly help him though

A similar car as far as setup, with same motor and header did a 12.4 (honda tech user name = allmtrallday )

 

it was 12.9@105mph 1.9 60ft with BFG drag radial.

 

Nice Car nice motor

 

Nikos bringin us some more K series goodness.

 

Very impressive!

nice

 

any more pics of this EG?

 

extracting power out of a stock K20 is already so cut and dry at this early stage.
im impressived without a doubt.

 

Restrictive header Gemometry? please do elaboaratE&gt;?

funny thing is that if your speaking of header design engineering etc. the toda header is more correct then the dtr especailly for a tri Y

a tri y on a 180 firing impulse 4 cylinder engine with a firign order of 1-3-4-2 you would pair the cylinders that are 180 degrees out. hence the toda pairing of 1-4 and 3-2

As well as the toda collectors look like they are placed @ the correct header length where the DTR header has them way down the primary tubes. this is fine and will work well as shown above and the dtr will probably work great for some stock applications

But on a well developed high output k series engine the the toda header should shine through as being superior

Dont get me wrong i like the str header and danny is a nice guy not trying to clwon anyones stuff casue it makes good power just trying to prove a point

and the numbers that you were providing 220 with header those numbers were on a tuned k pro

the most i have seen a untuned k put out with i/h/e was 215. something and that was by joe

bwahahaahahahaahahahahaha. i was so "impressived" that looking at the K20 gave me a hard on and the inability to freaking SPELL!!! LOL

thats why K-series got me too.

 

Are some images missing?

I am sorry it you misunderstood my intetions. Not trying to clown anyone...

i have seen rsx type s with toda heads and headers +toda flash making as much power as an internally stock k20a2 with DTR header +k pro and some mild head porting... There has to be an explanation for this... I think it is the header. You are in the header/collector business, I am not and do not know much about making a header. But when I see excatly same setups being 15-20 whp apart, I put two and two together, that is all..

Does dtr use your collectors? I know the true race header does, and that makes good power too... Hytech, dtrfab and true race do look alike afrer all.

Nikos

 

point 1 true race tubing pack may be the same but thats how it came out i specified the design on that header length dimensions etc.


Toda heads as in a reworked race head or? cams and valvetrain?

No dtr doesn't use our collectors, gotta remember its not the collector itself thats crucial; sure it helps but it is the sizing that counts

There are so many variable out there such as tuning dyno etc on and on it makes it extremly difficult to do back to back comparisons

 

umm I don't see why you guys are using 104 octane fuel??

any reason for that high octane..?
