Hi,
Just wondering if anyone has done headers on a 3rd Generation if so how much did it cost and what has the difference been in performance?

And also if anyone knows of different options what are they?

Thanks

Costs, questions, powers and info...

Hi there, couple of weeks ago i ported, polished and slave the have head on my ralliart engine. cost for the work $560 4 57HP extra power at the wheels. im happy with it.

If you were so keen to see the thread terminate Satan then you should have simply posted the links in the first page instead of dragging the thread into a second page with your comments.

Rockford Magna, don't be baited into an arguement on this forum as I am sure the moderators will not take the time to decide who done what first.

If those threads do not contain the answers you are looking for then I would suggest your local exhaust company might be a good port of call. Do a ring around for prices. As with everything else you will get what you pay for. If you want to go all out from what I have seen said RPW headers are good money. Pacemakers are a good second. I myself have Wildcat and find them not too bad at all.

how much did u port them?

didu do it urself or did u get a shop to do so?

was that power

with out a tune? ie stock ecu

I am also extremely interested in what you have done.

Me too

u must atleast have a decent set of cams and a piggy back ecu? ... cos i dont know how u could get that much power gain from that sort of mod without supporting mods ...

but if its true, damn good work

:stoopid:

:bowrofl:

so you basically claming you got around 60+kw at the engine, just from a port and polish and head shave??? :doubt:

for $560

why am i wasting 7k on a supercharger for less of a gain?


dyno pics or ban lol

To be slightly fair, he did say "hp". How much got decked off the heads? MMAL reckons head decking is *BAD* so do some other experienced Magna modders that haven't spoken on this forum for a long time.

yeah apparently if u deck anymore than 2mm u begin to have clearance issues etc

from what he has told me he has shaved off a very little less than 1mm I think.

so the ralliart already had higher comp... and now shaved heads... u going to run avgas?


yes HP he did say.... at the wheels... meaning it has to have been dynoed.... but what was the baseline? a std 3.5L vs the modded ralliart unit??

MMAL reckons head decking is *BAD* so do some other experienced Magna modders that haven't spoken on this forum for a long time.

It's worked for me :cool:

how much was urs decked by?

jason told me a while ago that 2mm or more and u start to have clearance issues, but it can still be achieved just need more mods apparently ( im not as mechanicaly minded as u and jason)

Back to the topic of the original post..................

I got my extractors fitted 2 weeks ago and i love the differance its made, the torque is great.

RPW Race $760 fitted

Exactly the type of comparsions i was looking for.

Also would be interesting to hear peoples comparsions on exhaust systems to suit that they have found to be the most effective in terms of power and value for money?

I got the lukey Rear muffler ages ago and now the extrators...

the rest of the system doesnt really need to be touched cos the 3.5's already have a 2 1/2 inch system. the muffler cost me about $250 fitted i thinki kept it hidden up in behind the bumper and it took about 6 months before and of the WA guys realised id done the muffler.

BUt yeah driveability is much better now, the car pulls harder in any conditions

Yeh there are a couple of ways to go with exhausts and headers. I found a good difference when i put my magnaflow exhaust and minor alterations on the rest of system.

When I got the new exhaust/extractors/muffler i immediately noticed the diiference. The top end power was opened right up and provied much more power above 3500rpm. Did really start to notice the flat spot though but Barry's kit helped with that.

I had to go a slightly different was with the exhuast. Although the 2WD exhuast isn't too bad the AWD is a twisted nightmare, so i had the guy at the exhuast shop do a custom job in stainless steel for me. Was expensive (really expensive), but worth it!

What extractors did you put in? Also could you go into the issue you were having with the flat spot?

http://memimage.cardomain.net/member_images/12/web/2184000-2184999/2184691_8_full.jpg

I fitted my pacemakers and a 2 1/2" manta system at the same time (cut out the mid muffler sas well). I wish I had it dyno'd, because I noticed quite a big difference in torque from 2500rpm right up til the redline.

It pulls a lot harder!

Different. How much did it cost you fitted?

I put in HM Extractors but while good they are VERY VERY pricey. RPW & Pacemakers are WAAAAAAAAAAAAAAAAYYYY better for the money. This is the web site for HM http://www.hmheaders.com.au/. Regarding the Flat spot it is well covered in this thread of Barry's - http://www.aussiemagna.com/forums/showthread.php?t=25097. Due to my fair amount of N/A modding it was pretty noticeable but is all good now.

I really like the Magnaflow muffler as well it has a nice deep growl but looks stock (i dont want to be a cop magnet especially since my car gets enough attention from them as it is cos i know most of them in my area).

One thing i would like to bring up for AWD owners is despite the fact that the exhuast guy was reccomended to me through REDBACK Exhuast systems he actually decided to go with the Magnaflow when i told him what i wanted with the new system i.e. While asthetics are nice i was after performance. The guy is real nice guy (names Darren at Mittagong Exhuasts, Mittagong, New South Wales) and has worked on alot of V8 Supercar stuff from what i understand. More importantly he's a picky guy. While it may take a little longer to get the system installed he always makes sure that it is done just right and that everything is running perfectly. Its a good work ethic and i was really impressed.

Regarding the Extractors they are great for opening out the top end of the rev reange but really do nothing for the low range. This is more an issue for me cos i have AWD, and want the low down power sometimes, however i am planning other intake mods to increase low down power (Higher Flowed TB, EZ Boy's Intlet Manifold - when finished etc.).

Different. How much did it cost you fitted?

I fitted them myself (with a bit of help). I don't really wanna divulge how much the parts cost me, cause I got them at mates rates.

But if you wanna a full cat back system and pacemakers like my setup (but fitted)... I'd probably budget to spend around $800.

Interesting forum yet havent had the chance to read the whole thing. Did you fit Barry's Kit and does work?

Yeh i have already set up exhaust system and be sitting on the thought of Extractors so getting an idea of price and the best to go for.

So the RPW or Pacemaker Extractors you would say would be around the $400 - 500 fitted?

And to solve the flat spot issue a kit like barry's. Whats the reports with this kit?

Excellent thanks. Well look into detailed info of the kits and look at purchasing.

To summarise the 10 threads that were created in the past month that covered this...

Pacemakers. $650 installed. RPW long race spec $650 + install.
Pacemakers and RPW both have long primaries and similar designs. Pacemakers are 1 1/2" diameter and RPW race are 1 5/8" diameter.

Don't know much else about any others, but from all the other designs ive seen, they're the only ones I would look at.

These will give you some more mid range punch.

Flat spots often are induced with people put in K&N filters, especially pod filters.

Excellent info Anon appreciate it. No one has gone out and said is 1 is better?

Would you say the slight size difference would sway u one way or the other. Obviously looks like the Pacemakers are the way to go for price if they are on par! Would you agree?

Nobody has done back to back dyno tests coz well....no 1 wants to by and fit some extractors just for the hell of it.

The general consensus of the forums is that if you have the money and value getting every last kw out of ur mods, get the RPW long race spec headers. If your on a budget and want the best power to dollar ratio, get pacemaker.

I have pacemaker and am happy. But I always wonder 'what if' I spent the extra money and went for RPW.

Well thanks again, i havent read any info to sway me one way or the other they both seem to have great results but obviously some rate the RPW's a lil higher.

If anyone else has either installed and has an opinion it would be great to hear.

The more info the better.

Hi there, i got shaved 5 thou off the ralliart heads which i which was done at my mates shop. custom made cams with 290 degree lift and ralliart heads full deck out port and polish.

Dyno. stock - 134 atws
head work - 167 atws
secert work - now pushing 181.6 atw with lsd

the 167 was with the cams yes?

thats pretty crazy cam isnt it ( im not 100% familar on what a big lift for the magna but i think the ralliarts are something like 247?)

so 167 atws with cams, head work and ecu? obviously ecu yeah?

anyways congrats on that!!! awsome work

good work!! whats the torque like??

290 lift?? the cam i had in my val had 510th lift...

whats the idle like?

i think he meant 290 degrees duration, but yes, that's a lot of duration no matter which way you look at it. Standard Ralliart duration is around the 248 degree mark.

My cams are 296 degrees duration with about .345" lift. Not sure what standard lift is, but whatever it is regular ralliart cams have about 10% more lift.

I believe my heads were shaved by about .040"

Does your mates shop want more work? I assume its in Sydney.

yeah a fair bit of duration... lucky with modern technology etc... you can get it to idle smoothish and run nice... my val had just under 300 deg and 510th lift, idled like a drag car... :badgrin:

i havent got the manual on me, but ralliart cams are identical to stock but with 10th more lift at the valve, and 248deg sounds about right...

but 181fwkw is pretty damn good, using rule of thumb.... could be approx close to 250kw at the fly wheel.... but thats an approximation..

but 181fwkw is pretty damn good, using rule of thumb....

Yes, it is, but my 207kW is better :badgrin: lol

if your car scares you.... how about black beards? 2 turbos just to rip your arms off lol

you would get a damn sore neck and have big smile driving yours though :D

Guys, what cams did you setup and what was the cost?

Guys, what cams did you setup and what was the cost?

Got my cams from Tighe Cams (http://www.tighecams.com.au/). They cost $1100 regardless of what profile you get.

Of course then you need adjustable cam gears, stiffer valve springs, aftermarket engine management, etc.

How have you found the quality of the Tighe Cams?

Then you start with ECU which interesting to see a lot of people use the Unichip which i would go for AVO.

Tighe cams are very good quality.

If you get long duration cams you'll probably find that a piggy-back ecu won't work for you as they're unable to modify the factory ecu's cold-start behaviour, and the big cams really mess with cold start and idle characteristics of the motor.

Myself, I'm running a Haltech E6X.

Yeh if you are going with cams understandable.

What did the Haltech set you back installed?

I paid $675 (inc. $45 delivery) for rpw headers couple of weeks ago, damn TNT express suck ass they must use camels to transport from Perth cause I'm still waiting. I'm getting them installed with a redback sports system.
I was getting the lukey system but I heard that the lukey growl is more of a drone? I'm getting cat back 2 1/2 is it worth not putting on the secondary muffler?

Yes, it is, but my 207kW is better :badgrin: lol
i'll get there one day.

Actually, when it's got the big tune in it - Brendans (cthulhu) car has more peak power than mine (207kW vs. about 196kW). And my car only scared me for a couple of weeks - now I want more power.

I do suffer from chronic whiplash, but I think thats more to do with my ****house gear changes than anything else lol .

Anyway - back on topic, I had RPW race spec headers with HPC coating on my car before the TT intall. I found they delivered a noticable increase in pulling power from 3000rpm up when installed in conjunction with Redback 2.5" cat back piping, and a 2.5" hi-flow cat.

And I'll be enjoying that fact right up until you get that electronic boost controller... lol I can't compete on low-mid torque though.

I know what you mean.. I should update my signature. These days, even though I know there's craploads of power there, without some kind of reference point (i.e. another car booting it along side) I don't really feel it any more.

I have HPC coated RPW race spec headers, same as BB. I can't say I really noticed much difference at all.. in fact I have a before and after dyno that shows no perceptible change.. but I think that's got a lot to do with atmospherics up here, and I'm not really convinced the dyno operator loaded up the same inertia settings either.

What I did notice, going down to the Gold Coast the other month, is that there is a BIG difference between a 30 degree day and a 17 degree night, even in my N/A car.. something you don't get to see much in Darwin.

I might get a price on the highflow cat and see if I can stretch it.

Pretty sure he was talking HPATW as that was his original comparison of a gain of 57HPATW. So that's 135kW, and it's impossible to even guess kW at the flywheel as ther're too many determining factors and variables. I could be wrong tho and he could be talking kWATW, in which case is pretty impressive from only a cam and port n polish.

Did you get a good deal on the install?

The guy supplying and installing the redback exhaust (midas) will put the headers in for free.

I had Pacemakers, 2.5" press-bent pipes (thru stock cat) back to a split before the rear axle to 2 x 2" pipes leading to two Redback mufflers with dual chrome dump tips.

Pacies cost $700 installed, the rest cost $900 installed (including $100 each for the chrome tips).

with no before/after dyno, all I can say is it seems to pull much harder from about 2500 rpm until redline.

The sound is loud!! :badgrin:

cheers,
.wook

For value for money the Pacies seem the way to go. Havent heard any bad reports on them!
