How can I cool the under-hood temps? Does anyone know of a cold-air-intake system for a '98 V70R? I'd like to free-up the air flow to the intake side in the process. Is there a larger down pipe available for the 5 pot?<br>Thanks,<br>Griff

Re: COLD INTAKE CHARGE (Griff_33)

I'm not sure I've seen one of these setup on a volvo. I think Kai may have something custom made on his C70. The main problem with the conal filters in the engine compartment is if they are not shrouded in some manner, they are going to suck in the hot air from the engine compartment. If you find one, I'd definately want to see an independent dyno run - Kai?<p>Yes, there is a race downpipe available, Larry help me out here I forget the company that was selling it. Eurosport has one, doesn't spec the R models though <A HREF="http://www.eurosporttuning.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=EST&Category_Code=turbopipes" TARGET="_blank">link</A> but it is very pricey.<br>

Re: COLD INTAKE CHARGE (83caddy16v)

The current setup I have doesn't really have a flawless way to prevent sucking in hot air from the engine compartment; however, from the way it's setup I'm pretty confident it'll have much less chance than those who just have an cone filter in place of their current airbox. Even if they leave the bottom of the air box in place, it wouldn't do much good....still too close to heat source.<p>Well, now think about it, I wonder how those(not on Volvo T5), who just have their cone intake filter attached right on the turbo, can prevent from sucking all the heat from the turbo next to it. Or maybe the reduce of lag makes up for it? <p>With my current setup I probably created more lag than I should have. Plus, I don't have any luxury to do seperate dyno testing to find out if there's a great difference in stock air box setup v.s my current setup. I'm hoping my current setup is doing more good than bad, plus butt-o-meter did show some increase in HP as the turbo spools up.<p>I've always dreamed similar setup as what I have but with some sort of enclosed chamber which has its top edge contoured to the hood line and sealed with rubber gasket when the hood is closed. Similar to the ECIS kit for the bimmers. But No, not like the BSR kit...a bit too weak of insulation if you ask me.<p>Even with kit like that, I doubt the heat insulation would be all that effective and 100%.

Re: COLD INTAKE CHARGE (The_one_n_only)

Well I'm waiting for my J&R cone from Engstrom. It has a little shielding around it, and it uses the stock 'plumbing' for fresh air intake.<p>We'll see how it does!<p> <IMG SRC="http://engstrom.net/scstore/graphics/bsr_4900701.jpg" BORDER="0">

Re: COLD INTAKE CHARGE (Red Rocket)

Yeah, that's the BSR one. Not too sure about heat shield it has....looks kinda thin. Or I'm just too picky. I'd want to some AT LEAST at ECIS' quality level and design.

Re: COLD INTAKE CHARGE (Red Rocket)

Please advise upon getting your system installed. I think anything will be an improvement over the stock box w/K&N. Has there been anyone who has vented the engine compartment? Whether it be cowling at the trailing edge of the hood or louvers in the hood or fender..... <IMG NAME="icon" SRC="http://********************/smile/emcrook.gif" BORDER="0"> <BR><BR>

Re: COLD INTAKE CHARGE (83caddy16v)

Thanks for the link, the price is a little steep. Does anyone have any data on the results of the 3" DP upon install?

Re: COLD INTAKE CHARGE (The_one_n_only)

I made an aluminum one a couple weekends ago, mocked it up with cardboard first. I hadn't seen any of the other designs before I made mine, or I would have copied a little more from them:<p> <IMG SRC="http://filebox.vt.edu/users/ebailey/images/S70/coldair.jpg" BORDER="0"> <br> <IMG SRC="http://filebox.vt.edu/users/ebailey/images/S70/coldair2.jpg" BORDER="0">

Re: COLD INTAKE CHARGE (musterdbom)

How does your's motor with the change? It looks cool. <br>Would like to see your work, in person. How far away is Blacksburg from Fredericksburg? Could meet you in the middle, if able. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <IMG NAME="icon" SRC="http://********************/smile/emthdown.gif" BORDER="0">

Re: COLD INTAKE CHARGE (Griff_33)

Motor does fine from what I can tell, no noticeable gain really, maybe pulls a tiny bit harder. I can really hear the compressor bypass valve now when shifting or letting off the throttle, very audible, like I put a blow off valve on the car, couldn't imagine wanting it any louder. Filter has a nice sound to it too, throaty sucking, foam sounds different than a k&n. All in all the box works well, I need to redo the top part where it seals to the hood, but that's cheap pipe rubber insulation, no biggie.<p>I might be headind to charlottesville sometime soon to visit some friends, if you want I could hang out in Harrisonburg for a while for you to meet me and check it out, I can go the crutchfield outlet and drool while I'm there. It would more than likely be on a friday evening.

Re: COLD INTAKE CHARGE (musterdbom)

I'd be coming across 33 to 11, into Harrisonburg. Looks like about 90 miles. Any chance a Saturday AM or early PM?<br>Griff

Re: COLD INTAKE CHARGE (Red Rocket)

Gentlemen, when I ordered my BSR stage 3 kit, I got it without the cone filter. The reason why is because Rolf at BSR Sweden said that they used both filters on the dyno, cone and drop in and there was no noticiable gain in HP, except a little throttier sound from the cone and a bit of increase in inlet temp to the turbo, no one can prove which filter works better.<p>So that's why I went with the drop in K&N on my car, until some decides to design a nice kit, like the one Kai is talking about, save your $$ and get other parts that you will benefit from.<br>My two cents.<br>Ralph.

Re: COLD INTAKE CHARGE (BSR_rckt)

That's the same experience I had with my S60.<br>I reached 300HP to the wheels with the original airbox and a SAM (Jamex?) drop in air filter.<br>The cone, green, was nice but I had a between the ears impression that it didn't perform any better, just a lot of noise.<br>I did some temperature measurements and the only higher inlet temps I could measure was after a while of idling, at least a few minutes.<br>After the recirculation valve had been activated during driving a few times the temp went down to normal very rapidly .

Re: COLD INTAKE CHARGE (Griff_33)

Well I got it on OK, over at volvospeed there's a discussion about the turbo air pump hose and what to do with that when you remove the stock airbox.<br>But anyway, no noticable butt dyno gains. You can hear the motor more, actually you can hear the turbo spooling louder. There is a low whoosh sound whe I let of the gas. I wish that it was a little higher pitched like a BOV.<br>

Re: COLD INTAKE CHARGE (Red Rocket)

The sound is the main reason I did the open air filter. That and I was bored sitting around a friend's shop with all the cool gadgets and had to do something creative with my time. I honestly don't notice a difference in performance, but the turbo spooling and compressor bypass valve wooshing is what I was after in the first place <IMG NAME="icon" SRC="http://********************/smile/emsmile.gif" BORDER="0"> <p>Griff, there is a chance it could be on a saturday morning or afternoon. I'm not saying it will be before January, but I'll definately let you know which saturday I'm going, I'd like to get a look at the R as well.

Re: COLD INTAKE CHARGE (musterdbom)

I also have a custom modified cold-air box around my K&N cone filter. I bought an aluminum water heater tray from Home Depot for $29, the largest one they have and modified it with tin snips and rivets. It's crude looking now but i'll redo it next spring to look better. It really does work, you can feel cooler air inside the box. It only opens to the front of the car and seals relatively tightly to the inside of the hood. I'll take a pic and email it if anyone's interested.<p>The car really steps up when the boost comes on. I've noticed a distinct difference. And so has my buddy in his WRX when he tries to stay with me <IMG NAME="icon" SRC="http://********************/smile/emwink.gif" BORDER="0"> !!<p>Tony P.<p>98 V70 T5M<br>K&N Cold Air Intake<br>Dialed-up Boost<br>Bridgestone RE950's

Re: COLD INTAKE CHARGE (T5 for Life)

Tony,<br>Please do. I'm looking at all the options. I'm in the replacement K&N in the stock airbox mode for now. I do want to free up the charge air as well as cooling it first.<br>My XR4Ti became a monster when I freed the flow on the front end....... The larger intercooler helped out measurably as well. Thanks for any input.<br>Griff <IMG NAME="icon" SRC="http://********************/smile/emsmile.gif" BORDER="0">
