Thanks for that updated info PR_Mivec. I wasn't at any time disputing your results, but that now does make more sense. So to clarify for everyone, including myself and confirm this if you can, the results you got with the computer in pure stock form matched the results we showed on our own test car - which is arond a 5 - 7hp gain approx across teh board, with a very similiary almost identical torque curve?

You are saying, and please correct me if I am wrong, when you tried to use an altered ECU values, that you then lost the horsepower and down low etc.

IF so thats great that yuo have the ability to mod the ECU - cause that will definitly enable you to tweak it to its maximun. Don't be shy either giving it some more ignition timing as well if you are able to.

And I didn't again, beleive you were bashing the product. Your reveiw came across as honest and straight forward. I was just trying to see what the variations were between our test car and your vehicle to ascertain what the differences were and the reason for the large differences. Every mod we did to our test car provided substantial gains.

 

yes when i used the alterations the performance dropped, im correcting it this week so lets see if we here can make he magic work...

 

yo pR mivec did you install them yourself or did you have a bodyshop/ someone else do it for ya?

 

i did it the only out of the ordinary int he instalation is to take out the front mount and the cros bar that holds it... is a 10 15 minute thing

 

PR_Mivec, tune that thang up so we can see some results. I will be correcting computer values as well, so I can do a setting with 93 octane and another on race gas, at least for general tuning purposes, since I will be installing that RPW cam when its due. So that will be setting again....but thats all the fun about it.

I recon you met my friend Berto aka LAncerGrisTurbo, for some parts good luck with the setup. Im doing some research as well with the intake manifold.

I bet that the results you had were N/A, no nitrous runs? MAybe it will do wonders that way

 

so if i had cai, cat back 2.25 rrm piggyback would i not gain any power by haveing the header is it worth the money with just the mods i have

 

PR doesnt have a piggy to my knowledge at least not RRM's.

Youll just have to adjust to get THE MAXIMUM performance for it, thats the big header they talk about optimized for continous tuning

 

can you do any value changing without a piggyback? and either way how hard is it to learn the interface? im good with pcs and all but don't know much about the compression ratios and all thatin a car....

 

The results to date that we have seen with our own test car is yes, you will still get enhanced performance with the headers without a programmable ecu system. Again refer to the dyno sheets we have posted with the header package. Also remember that the hp gains are not the only thing this header is doing. Speak with Chowetime who has had a chance to do extensive driving with these on the vehicle.

The vehicle rev's harder, rev's quicker, so much quicker it was continually hitting the rev limiter, increased acceleration, much better throttle response etc.

The main thing is if you have for example a pre programmed piggy back ecu, then this will not work with the header package, it WILL LOSE HORSEPOWER because it is not optimised with the header package. When it is reporgrammed to suit the package you will be fine.

That is the main thing to remember with this - this goes for any vehicle, not just the RA model lancer.

I fully expect that with our test car when we go to do some tuning, it will have some very impressive results with the headers and tuning with a cold air induction kit. But that will still be several weeks away.

 

I imagine that with that header and a good catback and a 75 shot will produce great numbers due to the enhanced scavenging effect. add a ported intake mani and voila. Low 13's

 

this quote was taken from page 10 of this thread there is more that I have added to it on the same page you should checkout what was said

I see many people are questioning how good these headers are and how much Hp has been achieved.. I mean why would you not question the results I know they are not huge gains so sure it may seem a little disappointing but I seriously doubt that there is another manufacturer that can claim much more than 10hp just from header mod on it's own... and for many years you have all been requesting from other companies to manufacture something for the car and all have said "too hard" " too expensive" "no gains can be made" ect ect...

Now RPW have made a set of headers and other companies have decided that maybe there is some gains to be made so perhaps they should make some as well... Like RPW have said I have been driving around with these headers for a couple of weeks now and I can feel the difference in the way the car drives via several ways
1) the car revs so much easier
2) much more throttle responsive
3) does not feel like it is choked up anymore
The choice is really up to the individual as to whether they will wait and see more results before saying the product does not work.... personally I think I am pretty lucky being possibly the only person with an RA driving around with a full production set of race design headers.

When I first got the car I will admit that I was very disappointed with it, now that I have the headers and full exhaust I am so much happier with the car, that is how much of a difference the headers have made to the car... I know your not supposed to post up here about street racing but I have to admit that everytime I see what could be a quick car I am ready to take them on and chalk up another kill.

I really do urge you all to wait a little longer and wait for the next lot of results before you make a judgement on them -

regards Christine

 

Yeah the reason i was asking is b/c im in debate as to what my next mod would be and both the ECU and header are on the top of my list. i'm leading towards the header first b/c i don't know enough yet to start programing the ecu.

 

Sorry if these has been answered yet but there is a lot of pages to read through so are there and gains from these headers and will they connect with the RRM downpipe??

 

you can't program/flash/replace the ecu, unless you are of the family of the PR genius that passed away with this knowledge (custom ECU I believe)

as of now, RPW and RRM have add on (piggyback) devices that can control certain signals going ?(to or from)? the ECU. AEM has standalone engine management for somewhere around 3000USD but I have not heard of anyone using it on the RA.

 

sorry Mike, the gains are in the last page or so, and no you can't use it with the DP. Both RPW and RRM have designed the header to be longer and therefore produce more power(hopefully) and don't connect to the downpipe in the same manner or location.
