Got this on Friday for my TJ Sports and its worth the $$$ - The improved throttle response it EXCELLENT. Absolutly zero problems with the car at all after the job was done. Drives just like it did before with a bit of extra go!

I was lucky enough to have Dave from RPW fit mine up! Man, does this guy know what his doing! I really wouldnt listen to anybody else in regards to Magna mods after listening to him talk and watching him work...

Thanks again Dave & RPW!

So everyone seriously get one if you havent already, its very well worth it!!

You Suck !!!!!

Do you you know what sort of power gains you got ??? :)

And what is the cost of the TB?

You Suck !!!!!

wtf - complete unecessary and an out of line post at that?

Do you you know what sort of power gains you got ??? :)

i doubt its a power adding mod. more so- if a power 'gain' was to be found it would be insignificant.

T/B's are more about improved throttle response and flow.
but generally speaking - more flow means more combustion (well, in theory, and cirtenly if you have a computer) which would then create - more power.

Great! means you wont have to post here anymore, and any questions you have you can call dave direct :D

one less post about extractors and flowed throttle bodies! :nuts:

Ben.

I have an even better idea… why don't we just direct all our questions to Ben, as he is obviously the new Magna oracle. After all, who can resist the GOld BOosted BOoya? :bowrofl:

(comments were for a laugh too - fullstop) :D

funny clown eh :nuts:

haha.. its all good :D lol

wtf - complete unecessary and an out of line post at that?

Actually it's because gremlin got the part and ralliart boy is still waiting on his, he didnt get it installed by Dave while he was here...

But I do understand it seems out of place, but now you know the story :)

Thought I'd just clarify as to why I didnt delete it.

As I understand it the high-flow throttle body probably won't give you much in the way of a peak-power gain, but by allowing more air in at part-throttle openings you should get more power over the rest of the rev range.. so you'll probably end up with a higher peak torque but peak power will remain much as it was.

make sense? :)

but by allowing more air in at part-throttle openings you should get more power over the rest of the rev range..

Not really. If more air for a partial throttle opening ... why not just open the throttle some more. The TPS will register lower for a given air flow now ... probably why the engine feels snappier ... its giving you more for less throttle.

A bigger throttle body's real gains are heaps more FLOW at near WOT and WOT not at partial. Its all about CFM :D

Fair enough, but this isn't a bigger throttle body, it's a throttle body with some of the crap honed out of it. It's still 65mm diameter. At WOT you're still only letting as much air in as you were before it was honed because the butterfly hasn't been changed and the bore is identical.

Booya, i didnt actual i mean i wouldnt listen to anybody at all ever. I was just saying how impressed i was with his work.

And yes i COULD contact him directly and not put posts up here if i wanted. I think ALOT of people already do that and why not, heaps of the knowledge that is on this forum is from him anyway.

Don't get all upset cause im saying that Dave is the man to talk to, im sure i'd say the same about you and Dallas if i came and watched you guys work and listen to you talk.

Two things :

1) I should have explained my comment - it was a joke between Gremlin, me and all of the NSW guys that attended the cruise on Friday night, it was nothing personal or meant in any other spirit than a joke.

2) I agree with Gremlin in that i have a lot of time and respect for Dave after meeting him and i certainly will not hesitate to call on his assistance in the future. Im sure Booya is knowledgable as well but he seems a bit insecure about Dave as everytime his name is mentioned, he is quick to put him down. Come to Sydney Booya and met the guys, share your wisdom and help us out. We all have open minds and im sure you will win us over too if you can respect us the way Dave does.

did you not read the bit under my name? :nuts:

"(last comments were for a laugh - fullstop)"

i have respect for dave and for anyone who tried to put their 2c's worth in. infact dave has helped me in my quest so i have nothing aganist me.

but this is a forum, and no matter what you say, you can never really express the true "tone" of voice, thus, it gets handled in many-a ways. most which are far from the point trying to make.

i thought most of you would of looked at it form a humor point of view, but i guess not.

So.........the high flow throtle bodies are good :D ,

Has anyone bored out the Magna throtle body with success????, as in no side effects like sticking...etc??? :P

Yes they are good I'd recommend it - I had mine done about 4months ago, it basically makes real life driving (part throttle burns) a bit more fun - more responsive at lower revs (though no difference at WOT). plus its good practice taking off the TB for when you change the rear spark plugs :D

No probs Dave.

Parts arrived today so jump back on a plane and head back over here to install them and its all forgotten about.

I got mine last week and installed it last Sat - after couple of nights of sanding and smoothing it to get rid of the imperfections on it - almost managed. (I can see Dave of RPW grinding his teeth and mumbling: that bloody Killer whingeing again...) At ease. I'm just a very perfectionist kind of guy.
Anyway, it took me almost 3 hrs - the damn water hoses were a pain. ECU is finally starting to settle down with this change and auto gear changes are ok. I might need to play more with the TPS adjustments. And perhaps fast idle too. After all, this TB comes from another engine, so we cannot expect it to sit 100% immediately.
Cruise was bit funny first, at 65 kph range - it was adjusting speed constantly. Obvious result of more improved response at the low BF opening. At 120 kph it was smooth as before.
Whether the cruise functions are related to some other factor like ECU or TPS, I still need to fine tune and test out. Haven't driven it too much yet to give 100% conclusion on this one.
Verdict:
Recommend!!! Makes a snappy take off on 3L Auto, compared to STD set-up.

What comes to allegations that Ben (BOoYa) feels threatened about RPW – I tell you guys a secret (well, not anymore). The Golden Magna is not Ben’s, belongs to his Grandma. Ben knows nothing about cars, barely can open the door without central locking remote. He actually owns and drives a 1974 1200 cc Lada.
So there.
And this is all true! :cool:

That's always the case - $ vs quality.
To enable mass production on these items, you might need to puchase certain honing tools and work station to improve quality and work speed. And how much would that add on to the price then.... sigh.

Yep, I'll play with the TPS some more. It seems pretty decent now anyway. Fast idle is bit high, tho. Might need to attack that next.
Anayways, as I said, this product is worth to consider for anyone who doesn't wanna drive like a Granpa. (hey - no comments there from anyone for me being the oldest on this forum!!! :cool: )



Actually we are doing more work on the finishing look of the units to try and make them smoother still and make them more of a polished look. But its the ultimate balance between looks V results V price.

To sum it up for the price we are marketing it for we cannot do a lot more in terms of looks and keep it at that price.

To get it a polished look woudl involve at least anouther 2 hours of work for no major gains other than anther $100.00 price tag.

Its a tough call so we are now buying some new machinery to smooth them out some more but it will never be quite as smooth as the standard ones but the gains are still there.

TPS is a major factor with the running of the unit - so definitly it will affect driveability more so on an auto which is more dependant on it again. If all else fails go to a mitsubishi dealership and just say that you were recomended by your mechanic to get the TPS reset.

no fears though your comments have been noted :badgrin: and I am glad it all went well for you.

when i 1st got my bored t/b i found it really hard to drive at 60kmh, throttle seemed too sensitive needing a very light touch, but then got used to it after a while. i did also adjust tps about 1 cm clockwise to prevent early upshifts.
i dont think the stock t/b causing any restriction, looking at it it appears much smaller than the intake manifold following or the rubber piping behind it, but then if u look inside the maf sensor this opening seems much smaller again.
i think the extra flow potential of the bored t/b would only show at higher revs than the 6'000 factory redline or with forced induction. :cool:

SO the throttle body would work very well with a turbo? What if you get a piggyback ecu with the throttle body will that help smooth out at niggling problems with the t/b
