What brand of otr? I know their are a couple that allow the maf
to be retained if needed, the Sureflo is one. I ran the Sureflo
with a maf whilst in the NT, now mafless with the cam.

I am using the ebay type its quite good. I am asking because my tuner dosent really like maffless tunes.http://i146.photobucket.com/albums/r256/ANDYSONE/XENON.jpg

A lot of different OTRs can run MAF.
The G&D above is the best but really hard to find.
Orssom do one, Sureflow one does... call a few melbourne sponsors. There are a lot of designs that aren't common on the forums.

No offence, but if your tuner isn't confident of producing a good mafless tune, Id look elsewhere :(

I've got a G&D OTR sitting in my shed. Top quaility and they work well :)

[andypower5.7]

Can i ask you dademOn why you keeped your maff on and not going maffless, as i can do it to mine aswell just have to cut of to make shorter were it meets the throttle body to fit. I dont want to cut anything yet until i am sure not to go maffless which is a hard one.

I go the same tuner as the OP and it's not that Mario isn't confident in producing a mafless tune (My car is mafless tuned and he did it just fine), his personal preference is to retain the MAF for various reasons.

Should get together with UT for a drink :rofl:

[dadem0n]

Ah Mario :yup:

Thats not my pic, just showing you it can be done :)

[andypower5.7]

Hows it going cbwolf thats what Ross told me as i just called him before and doesnt really recommend a maffless tune personal preference like you said, and we should catch up. I will fit the OTR just trying to make my mind up to keep the maff or go maffless as he told me there wont be much of a difference from maff to maffless, but there will be more of a diff going with a OTR intake its self. If there is only a few rwks in going maffless and a OTR is it worth doing really.

[cbwolf]

Yeh Ross went on this huge speel last time i had a chat to him about Maf vs Mafless tunes. Both of them (Ross and Mario) seem to hate mafless, i'm not really sure why, but i don't really think it makes much of a difference.

Great guys tho, the both of them :thumbsup:

It's kind of become the preferred tune at most tuners.

And as far as using a MAF on an OTR, it'll work just fine. But i'm kinda anal with things and i just see the MAF as a restriction to airflow, so any restriction, regardless of how small you can remove, is a positive.

Hell, i'd run without a filter if it wasn't really important.

[DaveHAT]

With the "Ebay PT copies" I think you'll have some problems getting it to work with the MAF Andy.

I just purchased one of those intakes to check the quality ... I wouldn't be overly keen to go cutting into or modifying it in an attempt to make it fit ... otherwise you might end up needing another OTR.

(I relisted the one I bought the day after I bought it ... what does that say :lol:)

My advice ... if your tuner insists on retaining the MAF ... get another OTR such as sureflo, Orssom/Marrano's/G&D etc ... or stick with MAFless.

Thread about the sureflo OTR with MAF ---------> http://www.ls1.com.au/forum/showthread.php?t=43540&highlight=illucid+MAF

A good MAFless tune these days should be equally as relaible and consistent as a MAF tune.

:)

PS Well done with the HID install. :bravo:

[andypower5.7]

Thats right cbwolf i would run mine without a filter aswell but its to risky and daveHAT thanks about the hid install mine is fibreglass it can be cut for mods but i really dont want to and it fits really good as i already bashed down the radiator and air con condenser to make it sit lower. I am getting to that stage when i will say stuff it and just do it and what happens, happens.

Fairies nuts Andy ... you should do what you're happy with. :)

Be careful if you got cutting the neck of the OTR to try and get the MAF in. You'll need to find some silicon stepper/adaptor piping/tube or similar to mate the OTR to the MAF which may be difficult to source.

Also ... if the fibreglassing on your OTR is anything like the OTR I purchased ... cutting into it is likely to weaken and crack it. It'd be a shame to waste your hard earned in an attempt to get the MAF to fit onto an OTR which is:
A: A poor copy of the original.
B. Not designed with the MAF in mind.

I hope it works out whichever way you chose to go.

:cheers:

[andypower5.7]

I hope it works out at the end aswell cheers mate.

Just remember if you don't get a real good seal with the maf it will
run like a dog and let dirt into your motor to boot. I had my fair share
of problems getting the maf to seal with the Sureflo item, and that is
meant to take a maf. Ok once I sorted it though.

[Millsy]

how did you sort it out? if you dont mind me asking, im thinking of buying a sureflo otrcai so lucky i read this thread first before buying one, cheers

Millsy

[andypower5.7]

Just by alot of researching alot thats for sure and by my tuner if thats what you mean. As when you get to do one of these mods you want to find out all the facts before going ahead. I havent really tryed yet for a final fit to let you know all the steps as i only put it on for a short time to see were i need to bash down my radiator etc for more clearance for fitment so it clears the bonnet when closed.

Just using some of that sticky foam Millsy. You can buy it in various
sizes. Wrap it around the part of the maf that goes into the sureflo
intake and force it in, the tighter the better. You will also need to
put a small groove in the base of the maf to accept your maf wiring.
I also found that the filter gets very dirty in a small round area that
is identical to the size of the maf entry (funny that). Some say to
reverse the filter to give a better gap between the filter and maf,
I just found this made sealing the lid harder due to the filter sitting
higher than the base. I ran like this for over 2 years in Darwin with
no apparent adverse effects but feel the intake is much better suited
to a mafless application.
Not trying to bag a sponsors product, but in addition to the above,
my lid has started to crack a little at the rear and the tube that goes
from the T/B to the base separated requiring me to reglue it with some
strong adhesive.
In finishing though, it served me well for what I required at the time
(a maf tuned otrcai) and still serves me well in a cammed mafless
application pushing just shy of 300rwkw with one of Sureflo's 3.5
medium exhausts (the quietest one) :)
Cheers
Rod
Edit: Assumed you meant me when you mentioned Sureflo?

[team illucid]

I have a Sureflo one - still using the MAf - 3 years and going strong.

[Millsy]

yea i was refering to you BLACK346, thanks for the info, i like the look of the G&D product retaining the maf, would cost around $600 though wouldnt it? cheers

team illucid - thanks for the info, you just added a bit more relief

Not sure on the pricing mate, but that G&D unit certainly looks
the goods imo. If I was doing the whole otr thing again I would
gladly fork out an extra Bradman to have that over any of the
plakky or Fibreglass ones on the market :)

Agreed :bow:

[cbwolf]

I prefer my Higgins polished aluminium one over the G&D one personally. But they're both good products.

[Evman]

Could try your hand at making your own...It's really quite a bit of fun :)

Greetings Andy and all...

I would like to let everyone know our position on Maff -vs- Maffless so there will be no confusion.

Mario & I (Ross) are of the opinion that removing the Maff serves no useful purpose unless the car has significant modifications that result in the Maff running out of frequency.

Basically, we have found that most cars developing less than 350kw atw do not gain anything significant by removing the Maff. Cars prior to the VZ do have a more restirictive Maff but changing to the 85mm Maff fixes that problem.

If you are searching for those last few kw then going maffless will get them, but unless you really have to have them we would rather leave it in.

It is not that we can't do maffless, or that we are not good at it, we just prefer to leave it in unless either the customer has their heart set on Maffless or the Maff cannot cope with the demanded airflow.

Please do not take this as any criticism of tuners who prefer Maffless. We are NOT saying that going Maffless is the wrong thing to do! We have simply not found that removing it improves performance by anything significant and see no reason to take it out.

ps. Andy, do not cut the OTR. If it does not support the Maff or you really want Maffless we will do it. You will be happy with the result regardless of your choice.

[andypower5.7]

Thanks Ross i rest my case. Well said i know maffless wont be much of a difference over a maff tune but surely it wont be worse, as with a OTR setup it would work better with a maffless tune as i would of thought maybe i would leave the maff on the OTR INTAKE but it needs the neck to be cut of about 80mm or so to fit the maff in between which there would be nothing left of the neck thats why i would rather go maffless thats the main reason to retain the neck. And like you said i dont want to cut my OTR just to fit the maff in for the sake of retaining it hopefully i will see you soon thanks Ross.

[HSVJPL]

Also to have near the same performance as mafless toy will need to purchase the VZ 90mm MAF and patch lead as you have a VX (@$500 i think)

[holdenfreak]

Gidday Guys,
I've been waiting some time for the 'genairation' otr for some time, i have a maf tuned vz & wish to retain the maf, have been looking around at different types for some time. Does the 'orrsom' otr fit a vz, i see the pics of it with a maf! Also found on ebay one called the 'xtreme otr' it looks ok, & they say you can fit a maf to one at additional cost, any tried one these? Have a look & see what you reckon.
Regards Holdenfreak
