Velocity stack position

[Euro08Jaz]

at the end of the day we know what we drive, doesnt mean i cant enjoy learning about it and trying to do my best to improve what ive got, i watch as people modify their cars and appreciate the amount of satisfaction and pleasure they get in doing so.

No shit NA engines are costly and difficult to milk kw's, you all think we do it because were stupid?

[EUR003act]

hehe MPS only has 145-155kw atw... ill easily get that
i do see results on the road, and i do pass those cars...

as jazz said... i choose to drive the euro...

Trippers! Save your money blowing cash on chasing 5-10kw power increases (or decreases as it often turns out with dodgy honda modifications you cheap skates) and purchase yourself some forced induction power. Supercharge or turbo, screw naturally aspirated headers with your high flow cats or cat back systems and buy a custom exhaust manifold and strap a turbo in place!
Or not! But your 10kw power increase aint going to change the fact you probably drive with your arm out the window and your knuckles draggin along the ground causing more drag than your power gains! hahahaha
Velocity power stacks hahahahaha hahahahahaha

1.The dyno was an inland dyno.
2.The car in stock form produces 140kw ATFW at the coast
3.My dyno produced 164.5kw ATFW inland
4.I have been reliably told that you typically loose 15kw inland
5.That means 194.6kw ATFW at the coast
6.That's a 54.6kw ATFW gain?? Sounds too good to be true
7.The guy that did the fabrication is the most respected local person in header and exhaust performance.....with articles in leading local performance magazines. He has checked his equipment, and is convinced that is the right BEFORE no......so much so , that he is taking my car back to redevelop his header and exhaust system, as everything has been 'thrown out the window'
8.As this was a handmade, time consuming DIY mod....and reading so often that when ppl do DIY mods, they never get them dynoed cos the dyno costs more than the actual mod.....I wanted to proove that sometimes, it works to all those that have been ridiculed or talked down....hence my mod, prior to a performance part fitment....granted that this is a MASSIVE almost UNREALISTIC number gain, I was in utter disbelief myself. I still wish I had done an independant dyno prior. But hey, thought I was doing the right thing
9.I am sure that this dyno may even cause myself to be ridiculed...I don't mind, the figure sound ridiculous to me as well....at least it's one better that so many other non dynoed DIY mods.....and I have some trusted local backup (Skunk2 incl) that is working round the clock for a solution.

10.Local fabricator promised me and increase on my 1st run or my money back...either way, I do not loose!!
11.If for some cosmic event he can improve gain, I'll get the car dynoed independantly elsewhere to support his results or not.

12.Either way, watch this space if still interested....and try not to shoot me down

13.Over and out

sorry to break it to you buddy, but theyre only 140kw at the flywheel... most euros put down around 100-110kw ATFW stock depending on the dyno...

rofl this thread is hilariously funny.

When you mean 'put down' you mean at the wheels right??!!! So it should read 100-110kw ATW and not 100-110kw ATFW....140kw - 23% = 107.8kw (flywheel to wheel conversion %)

"Building Honda K-Series Engine Performance' suggest the K24A3 @ 160hp ATFW? Which equals to 119kw? Sorry, just trying to understand the facts here....cos our Honda is sold locally as a 140kw ATFW power plant (or 187.7hp)...Book must be wrong OR is there a difference between K24A3s?? If so, I would like to know which items are different....sorry, learning curve for me.

Which makes the dyno even less sense....I hate calculations...next dyno on redevelopment must be ATW

BTW : The second run was without the minicat...took the car back the day after for fitment....so the 2nd run is definitely untrue. I am playing devil's advocate for the 1st run....I'll even ask that they service their dyno machine and get it checked just in case it has been giving false readings

On my trip down to the coast from inland (On Wed afternoon), the reading @ 200km travelled was for another 800km outstanding.....the reading @ 475km travelled was for another 475km oustanding. I eventually filled the tank once I had done 880km, cos it's fun @ the coast.

Just to clear up the confusion, in Australia, dyno figures are always referred to ATW, at the wheels. I guess that was where the confusion started when people thought that when you said ATFW that it meant "at the front wheels".

I reckon, you need to go back to the coast and dyno at that same workshop again now with your I/H/E setup. You can't guess what your baseline is at an inland dyno without actually actually running on an inland dyno.

Ahh....I'll forget abbreviations next time...

Install was done inland and both flywheel dynos' done inland as well...I don't have a baseline dyno, as I wanted to test my DIY mod (explained earlier). I'll get fabricator to give me his wheel dyno of the 2 runs....I'm sure it's just a conversion process @ his machine. Spoke to him yesterday, he is very interested in working on my car. He said

1.Dyno test as is (as minicat was subsequently installed)...will give a diff no now?
2.Remove his system and replace with my stock header and exhaust, and dyno at flywheel and wheel....He is just as keen to play devil's advocate and disprove himself / results OR reconfirm Run 1.
3.I have given him as much internet info as possible for fabrication, cos he is a hands on type of person.
4.He has been very interested in the firing sequence of the K24....said last time he designed a header for firing seq. was when he was in competition biking development. Which makes me think that the current header that he developed for 2 installs already on mate's cars may need rework??? I'll check with him.

This is off the book mentioned earlier...No-one has commented on the K24A3 kw question?



EUR003act : The RBC on the K24A2 (Page28 & Page29) only reported 4hp gain @7100rpm and 11 ft-lbs torque gain @ 4400rpm.

This is my friends K24A3 stock coast flywheel dyno...granted that not all K24A3's are the same from the same factory in the same country.

what was the K24A3 question? lol

hehe well myself and euroaccord13 have seen higher gains than that from the RBC... he dyno'd before and after fitting the RBC and got about 10hp gain at the wheels i think? plus a gain accross nearly the entire rev range...

im not a motor mechanic... but when i do mods to my engine i just apply basic physics... it has seemed to work for me so far... lol fingers crossed!

Why on the net and on the book it says the car is 160hp, when it's actually 188hp.....do we have some parts of the K24A2 that make this so or not....?

I had hoped you would say that, couldn't imagine spending the cash on such small gain....Going to Hong Kong in Dec on holiday, can anyone suggest any 1 place to visit for JDM toys from personal experience? I would love to have the 1st RBC in ZA...got the cash, just need to be pointed in the right direction.

In the US, their K24A3 is the equivalent to our K24A1. Our K24A3 is the same as USA's 2004-2005 K24A2 with a different ECU.

We did cover this b4, but you have a better memory than me. So, if I understand you correctly, if I did an K24A2 ECU swap, I could gain 200hp-188hp = 11hp (8kw) more???

Or is it not that simple like Windows plug and pray?

Anyone do this in OZ?
