Does anyone make an over the radiator CAI for the G8? I've noticed the OZ cars have them and seeings as I have that big ass hood gap it just seems natural.

No disrespect to board sponsors but I'm just used to seeing LS* engine cars with an OTR CAI.

I'm not sure there's any advantage to one, input?

There is advantage to them over the stock set-up in reduced IAT as well as increased performance - no doubt those two factors combine with increased airflow to help.

I see you have the ORSSOM one in your avatar, there is also one made by a mob named Russo Performance. Currently, they have a customer's bolt-on car (SS - same as G8, but with 6.0lt L98 engine, not L76/LS3) running 11s with their intake.

There has been plenty or R & D done into OTRCAIs over here, resulting in good gains.

Why not try one of those mobs if nothing is offered there in the US?

Cheers,

Thanks Macca, nice ride btw. I've found a few down under and JHP replied back to my inquiry about an US distributor so I'll maybe go with them.

No worries mate - good luck with it. If you google the names I mentioned in www.google.com.au they should bring plenty of info up straight away. (I'm trying to stay cross-forum safe!)

Thanks for the kind comment on my rig too.

Cheers

I've been getting a few PMs in regards to a US seller of ORT CAIs and have yet to find one.

Geoff from JHP was kind enough to reply to my question. Basically, JHP uses an US based distributor for their orders. Here's the reply.

Wonder who their distributor is in Cali.? Kind of an evasive answer. Anybody know anything about JHP? Anybody order from them yet?

I keep hearing that JHP sells the ORSSOM OTR CAI but the picture below has their website molded into the intake.

JHP also supply the best looking performance over the radiator (OTR) Cold Air Intake to suit the Pontiac G8, Chevrolet Lumina, VXR8 & Commodore VE. This OTR can be used with the air flow meter or maf-less.
$770 USD shipped. (See pictures below)

It looks nice, but for that price you could buy two regular CAIs and mount one on each side :rolleyes:

Yeah it's stupid expensive, it has to be near the price of a nitrous kit.

Bringing this thread back!

I wonder why no American company has developed an OTR intake? From my previous experience the shorter and straighter piping of an OTR is more effective than the long curved piping of a tucked CAI.

I would be curious to know if either roto-fab or new era tested an otr before defaulting to the cai? IF not why? OTR intakes in theory should be better performers. They would suffer no more from heatsoak than a cai being sealed to the hood...

We need a company to step up to the plate. I know I am holding out on an intake until I see the results of an otr setup compared to a cai...

I agree- I'm also intrested in OTR intake

Yeah, there are plenty available(seems the standard in australia). Just none that are made here in the states, which means a +$500 tag for an intake after shipping is all said and done. I don't understand why no american company can see the benefits?

just go with the russo otr it will fit .

I had a hard time seeing how the OTR would work because the gap between the hood and front clip seemed so small and restrictive. I took some leftover claybar clay and squashed it into a few areas to see what the gap really is. Turns out not to be so bad. The width of the OTR looks to be about 17" The painted deck in front of the hood latch is about 1 3/8in or 23 3/8 sq/in, the painted area where it steps up (latch area) is about 3/4in or 12 3/4 sq/in. In a nutshell the area feeding the OTR is slightly larger than the MAF 12 1/2 sq/in and not much if any air restriction. I'd like to find some mph comparisons between this and other designs. Decisions decisions...

Big question is how much???

^the one i have was less than $450 (was $700 US in AUZ), hopefully with a huge order, it will come down even more...

I hope so. $450 for a piece of plastic is crazy!

the $450 includes shipping from AUZ...

450 is a lot but still within reason, by far the best price I've seen.

hopefully i can bulk order some and get a hefty discount for everybody...

this one looks mass airless....

gotta pay for the best... why do you think most of the known Australian companies have their OTRCAI set higher than the sub-standard ones.... it takes a lot of research and time to get the right intake manufactured to yield the best results. Do a search on the aussie forums.... ls1.com.au and you'll see which ones are praised... vs the knockoffs that sell on ebay.

the biggest thing is trying to negotiate a fair price for the US market... as i said a fully loaded g8 here goes for $70000+ US there, so once you get the distributors to understand that, they will cut a deal with you...

the problem is..if you sell 10 at $750 bucks...your take is $7500. but if you can sell at 100 at $300 then thats $30k. i think i would rather take the $300 and sell as many as I can, then to sit on a big piece of plastic for $750.

But thats my opinion.

Roto Fab for ~20 RWHP @ $300 repeated by a few companies or ~12RWHP for $700? Yikes!

that 12 was untuned and in 100+degrees... both the OTR's that Cyclone and myself are talking about have been proven better than any other CAI in AUZ... besides, i already said, pricewise, the ones i'm getting should be close to the Roto Fab and outperform it...

they sell enough in AUZ at that price, which was why some of the companies weren't willing to negotiate... thankfully, im a good negotiator, lol....:)

20 rwhp... oh please... lets not start the CAI arguments.

that 12 rwhp gain was untuned. Could probably get about 30+ tuned. And the Roto Fab does not offer any benefits at 50 mph +

am get from the russo otr 35rwhp and it fit to g8 . aslo the orosem otr 30rwhp

Agreed...

I have emailed the Aussie company that makes one version. They were having heat transfer issues (from the radiator directly underneath) and were working to solve that problem. I see that some are making their way to the states. Can anyone advise if they have the problems with the heat resolved?

^i'll let you know soon enough...

Thanks, I do really like the Aussie CAI!

Hey Atlas what is the time frame?

hopefully within the next two weeks... the company shipped it monday, it should take a week to get here, and once it comes, its going straight to my builders...

What do you guy's think of this design. Made from ally and powdercoated, it has the bottom deflector to take advantage of the cold air coming in from the grill.

Looks great. Did you build it?

That looks good if it would work on G8 clearances, rad and hood.

Other than that i may have to have some sort of removable mesh for the billions of bugs i get on the front. :whine:

But that's just me!

Cheers!

Which CAI are you specifically refering to? I see so many here. The one you have ordered, does it have all the "Stateside" hookups such as MAS etc? Thanks

no MAF for mine, but i dont care, b/c my guys can tune properly and soon enough i'll have a wideband gauge...

wow ziggy that otr cai looks great!!! you should sell them!!

no MAF for mine, but i dont care, b/c my guys can tune properly and soon enough i'll have a wideband gauge...

So the CAI your talking about selling to other G8 owners, isn't compatable to our MAF? So people buying these systems, are going to have to spend even more money, getting a "proper tune" and "wideband gauge"....... or am I missing something? This type of thing would be good to know before purchasing. Just a thought.

any proper tuner will be able to safely tune the car without a MAF and without a wideband gauge... the only reason I am putting one in is b/c of future mods that i will have... this CAI is not for people that only want the a CAI and no tune, it WILL need a tune to go along with it... it will be just like the vector tune/rotofab combo on their site, possibly less expensive...:)

Speed density tunes certainly work but I would suggest having the car tuned at least twice a year. Different weather is going to effect the way the engine runs. I'm sticking with the MAF system for simplicity.

<-----------------From FL, lol... but you are right, northerners and anyone else who sees extreme temp changes should get a check up... most tuners wont charge for that, i know mine doesn't, but im sure there are many that will...
