otr comparison

[blu ute]

Hey all. I am farely new new to alot of this. can any one tell me how you tell what is a good otr or is it a matter of personal prefrence. any advice would be great.
cheers damo

[AMADR8]

hi mate, its more personal preference, they all make around the same power. i personally like the dus otr, it seems to make good numbers and looks very good

[blu ute]

cheers. are they all around the same price. $500 to $700?

[ssv402]

Hey, I have the Russo OTR and im quite impressed actually :), i have no idea about what I paid for it exactly, was a while now, but i do remember it was an alright price. Its held up very well over time also, good quality.

[blu ute]

i have seen the russo and like the look. i was wondering if the ramjet is any good?

[rosco]

my mate had the ramjet and thought it was pretty good can't remember the power difference between our cars i have the airhammer he has the ramjet with same mods and both tuned etc i knowh is made a little bit more hp atw and mine is 340hp atw with tune and cold air intake. hope this helps your decision.

[LS1-5.7]

blu ute, I bought one from F1 performance for about $300 and it's perfect. Prices will vary from that up to $1000 for the really nice ones. The Dus ones look schmick and work well also (about $700). The main things you need to worry about are the type of material they're made from as some absorb and retain more heat than others. I believe fibreglass is a good choice there. Fibreglass also assists in preventing the intake from sucking itself in under sharp acceleration. This reduces overall intake volume whilst it is happening. Also make sure the seal at the throttle body is perfect. The intake should sit in the engine bay nicely without hitting the bonnet and many come with side panels to make them look stockish but tidy. A last and important detail is that the intake can twist with the motor as it moves, without putting strain on the housing. Some are known to crack due to this.
Your fist cold start after fitting it will involve sounds you've never heard before and you'll see how much it breathes, and how did it perform without one before ? :)

An airhammer ??? getting same power as an OTR??? think it comes down to other things than the CAI ... there's no way a pod would give you more power than an OTR. Particularly of the engine is hot.

+1:goodjob: for Russo for me too ... and I think the Ramjet would be just as good.

They both sit in front of the radiator and give you a bigger surface area on the filter than the DUS/Orssom/Ziggy etc. BUT you have to be prepared to have your radiator tipped back on a slight angle to accomodate them ... which some people don't like for some reason. There are also issues if you have a trans cooler.

[Wonky]

They're all most likely within a few kw of each other, so in reality it comes down more to which one you prefer the look of. All the good ones are around $600 + or - $100. From what I heard the other night the Ramjet is $599 for forum members.

I'm with Cam (AMADSS) - I love my Dus OTR because it looks so factory and gave excellent power results for me.

Nice work !

[mattwalker]

DuS OTR for me too!

[Groboz]

DuS OTR for me three. :)

[1BEAST2NV]

Dus otr for me 4 :)

I personally would rather the "standard" look as it would help with the boys in blue (if they dont know what it is:))

[Fozdog]

Dus OTR for me 5! And because Dus had the best customer service I've ever had when I bought mine. (had some shipping issues but Dus worked hard for me and kept me in the loop - very professional and friendly!)

[simon.w]

I went the Russo ... and very happy with it. Would also look at the Ramjet if I was buying now ... seems like a similar "behind grill" design which allows greatest flow.

Dus Speed certainly looks excellent ... And I'm sure the VCM, Orssom and Ziggy are all good too.

Personally I'd avoid aluminium units purely because of heat ... but the do look great.

[BLACKVE]

I've had the RUSSO on both my Ve's have had the problem of filter moving everynow and then(used a little glue all good, they even sent me a new one), the russo has some awesome results and with it's design i'd recon the best airflow. having said that the DUS does look a bit more OEM. In the end the best price might win as they all seem to work well.

[blu ute]

Thank you all heaps. i think that chev recomended the dus. you have all been very helpful. cheers

How come it has a Modification Plate on it ?

Im on the Orssome wagon as i have tested a few and the orrsome holds it ground well.....

The Dus also has the behind grille design as below, but doesn't require the radiator to be laid back as the Russo does.

[sixlta]

another vote for the orrsom, great unit, great build, good value

[blu ute]

too many to choose from. think i will let chev decide for me. just want it too look good.

[blu ute]

would like it to be able to color coded too. does the orrsom require radiator to be laid back?

[Wonky]

would like it to be able to color coded too. does the orrsom require radiator to be laid back?

With the Orrsom you'd have to arrange your own painting, whereas I understand Dus can supply them in some colours. No need to lay radiator back for Orrsom.

[SSV8TE]

No mate...can be painted too just havnt got around to dressing the engine bay on mine yet

[matt_b84]

I prefer the look of the russo as it can be painted to suit the car. Smooth and tidy appeals to me more than factory looks.

[decoupe]

Where are the Orrsom and Russo available from and is there a website etc to get a look at one for a VY ?

[smokey777]

i got a Ziggy OTR

[VESSV8]

Ive got the Dus OTR on my VE ... Had to lay the radiator back on mine about an inch or so ..

[BOOGER]

My mate just got a Dus OTR fitted and I've got to say it looks really good in the flesh and has a good induction roar. I've got the Ziggy OTR and that's really good as well. Two totally different looks but both work well, just depends on the look you're after. I think the Ziggy is a little cheaper, at least it was when I bought mine.

[HSVREDSLED]

MAny moons ago, I posted that there should be a comparision done of all these OTRs'.....not on engines/cars but in a totally controlled environment. If more air and cold air is better, surely the test would not be that hard with the amount of techno gurus on here??

[xthommox]

Check out the VCM one. Sorry about the rest, but this looks great and so much more "factory" looking. Some come close, but they don't look as good as this one.

And also include the old & trusted MCAI unit with the 2nd hole mod - just so you really compare what meaningful difference the OTR (and your $$$) delivers.

Absolutely...also thow in a gutted out maf disconnected.


Personally Im not interested in "...I picked up 3 mph and two tenths with a XXXX OTR..." Too many variables.

Although not an MCAI, the APS pod filter in a box made the same power as the VCM alloy OTR intake did on my car: http://www.ls1.com.au/forum/showthread.php?p=1689578#post1689578

[dyno junkie]

If anyone's looking for a Ziggy, I've got one in the for sale section.

Or shoot me a pm.

has anyone put just a pod filter on the throttle body ???

Can I ask why youre swapping and what too? I would have thought this SS model were okay.

[XUV]

I meant just one big pod .

I've heard the growler is the only air mod allowed in touring car racing , well what qwas v8 lites .

[Wonky]

has anyone put just a pod filter on the throttle body ???

I had 2 different pod filters on my SSV sedan - pretty much the same power. When the Orrsom OTR was released I updated to one and picked up approx 15rwkw!

[Wonky]

Can I ask why youre swapping and what too? I would have thought this SS model were okay.

I'm pretty sure Badseed had one of these and picked up a fair bit of power (8 - 10rwkw from memory????) when he went to his Orrsom.

[SHANESVZSS]

either way you go , russo , vcm , ramjet , dus ect ect (to many to name lol) you wont be dissapointed and will get great results.

I PUT a harrop 2300 supercharger on

so the SS one doesent fit anymore i was geting 300rwk cam only with it

That seems to be true. Not that I'm an OTR man. I personally like to totally factory look.

As wonky said from the word get to, power differences appear to be fairly minor, so in reality the aesthetics (and to a lesser extent price) becomes the main driver for many OTR buyers.

I gotta say, i like the look of the DUS OTR. But i think ill be staying stock for a little while yet.

[Blakrok]

I think what has put me off buying an OTR so much is reading about the difficulty so many people are having fitting them at home. Most seem to need to modify the radiator or cut things or bend things etc hardly any if any seem to be a 100% bolt on.

Good enough for 11's and also just took it of for a Ramjet and the K&N in there has only been cleaned twice in 90000k's :) and ran up last year 390rwhp :):) cam only with MCAI

[Ginger_Beer99]

I've got a Ziggy OTR on a VE. Had a Walkinshaw POD with a SS inductions Big Mouth Induction pipe which I keep intending to sell . Pod was good, nice low growl to it, and extremely stock looking (Walkinshaw has a good finish).

Swapped to OTR for ability to go MAF-less, and found quality and fit of Ziggy unit to be great. Stripped radiator plastic shroud (5 plastic screws hold it in, tilted radiator (dead easy), and put in the OTR. No issue with cutting/shutting or rubbing.

I eventually decised to go for a stock look by trimming the original radiator cover to fit OTR using a straight edge a sharp knif0, and a bit of patience. Looks quite stock, and very tidy now. Then used the OTR as a mounting point for a catch can.

Really impressed with Ziggy OTR, car is noticably more willing to accelerate, unit is very well finished, and the induction roar is improved heaps.

[LS-SV8]

Hey everyone im new to this forum and ive got a question regarding the Dus OTR. where abouts can you purchase one in south east melbourne and to they all come in white or no?
thanks:)

[Plenty]

This is a no brainer, VCM Suites new VE OTR is an outstanding oem looking piece of kit, also will be most likely the only one to be adr comlliant. Produces great power looks factory and at $495 for a MAF version you can't go wrong!

[stealth vn]

i also have ziggy otr and nick makes a great product will recommend to anyone

[Popeye1]

This is my new setup, the last setup with the round K&N out of bonet ran a 11.8 this new setup after Russo fit the 42 pound injectors im hoping for a mid 11s.

Check out his website, he can ship it to you. They come in gloss black or gel-coat - and you can get it painted whatever colour you want

[skitzn]

hey guys,

i'm pretty new at this,

very informative thread , i have read it all and have been thinking and couldn't find the answer.

does it matter what size you throttle body is compared to the size of the otr?

or does the rubber hose thing that joins them accomodate for that?

thanks for your time

nige

[SirNemesis]

I found when changing from the standard LS1 throttle body to a 92mm FAST throttle body that the outside of the throttle body was the same size, only the inside is bigger, so no issues with the OTR.

[skitzn]

thanks adam,

it seems answered already.

thanks again

Duspeed VE OTR in red

n2RU6yVroNc

[2ajmanvell82]

When looking at OTR's and prices etc, i think the main things to look at are the inclusions they come with in the price, ie; if mafless is the IAT senso &r loom included or is that an extra cost, the fit and the looks, how it is going to work in wet weather etc and how strong and well fastened it is with a good flex joint at the Throttlebody.

My father on his VE SS is running a duspeed as these were at the time of purchase what we considered to tick all the boxes for us and include IAT etc in the price and looks very neat!!

http://i587.photobucket.com/albums/ss316/ajmanvell82/DSC03770.jpg

On my supercharged ve maloo i run a VCM OTR as these are great factory looking and alot of development has been put behind them and offer a good OTR for harrop superchargers, after having one and comparing the VCM OTR is great as it has a great price and includes everything u need in each application, mafless,maf and supercharged, comparing filters with my fathers, we have to service his more often as it doesn't have as much filter surface area so it gets dirtier quicker meaning restriction in air flow sooner.

http://i587.photobucket.com/albums/ss316/ajmanvell82/DSC04140.jpg

Both OTR's we feel are the pick of the punch for us and what we do. Everyday driving with a performance car and also works well when we do a track day or such with a neat/factory appearance.

Ask Chev as he sells heaps. Also I'm pretty sure he does a package deal on DUS OTR and tune.
