Interesting topic. I've heard people say the scoops don't help and even hinder before. Yes, many busses do have the holes from scoops added by po's. Personally, I don't like the look but to each his own. I'd rather weld the little holes in than patch the whole vent section from the po who hacked the whole area out, another common modification. I have 1 old panel, the po cut out the battery box on the drivers side and bent it down like a scoop, looks like it sucked up mud from the rear wheel very well. The carb intake volume is something to ponder too, I bet those 44's on a 2 litre suck half as much as the whole cooling system on a 36 horse! What about removing the engine cover or apron? I've heard pro and con there too- more air - disturbs the flow to the fan, which is it?
J Pickens, when you check your temp with that ir magic wand, what are you checking? oil temp, head temp, other? I mean, if you aim it at the cooling tin are you getting head temp or what? Just curious. |

Removing the rear apron will recirculate the hot air. Propping open the rear engine lid will also recirculate the hot air. Both not a good thing.
If you are running the 'sled' tin that connects the engine case to the heaterbox, you can get away with removing the front tin that straddles where the engine and trans meet. If you have a doghouse cooler, stab a dryer hose on the end of the outlet and route it so it wont recirculate back into the fan. Been running my bus like this for a while now. I can't get the engine to over heat, no matter how hard I try. Flooring it up a canyon while it's 100+ degrees, and it doesn't miss a beat. _________________ Eric Allred

finally a thread where everyone can talk about how much non-stock vw modifications SUCK!
i took the side scoops that came on my bus off and smashed them with a hammer so nobody would find them in the garbage and drill their bus for them. |

Hey Pickens, what did you pay for your IR gauge and where did you get it?
As for the scoop deal, it's really your bus and do what you want. If you really want scoops, go for Nate's and don't drill your bus. If it's already got the holes...I've had buses like that...just slap a set of fiberglass ones on.

It seems like it would be easy enough to utilize Nates clamp idea to secure the fiberglass/plastic scoops to the bus. Wouldn't it? _________________ Eric Allred

That's right! It's a good thing you came to the right place and ask what to do with your bus. WE are THE authority on what you should do with your bus. Unless we approve of it you are absolutely forbiden to do anything to your bus.
WE know. If you don't believe US, just ask US, WE'll tell you!

I calibrate test equipment for a living and the IR temp guns are usually accurate to within 10 degF. To test this, shoot it into your mouth and you will probably not read close to 98 deg. Just a bit of info.
They are good for a ballpark idea of problem areas. An actual oil or cylinder head temp gauge is much more cheap, accurate, and reliable _________________ ~Tarzan

| this is a little off subject, but I think worthy of mention as long as people are talking about IR temp gauges and the such. has anybody put an exhaust temperature gauge in a VW? I drove a diesel pickup truck last summer that had one and it was incredibly responsive. as soon as you put the engine under a load, ther temperature would shoot up. with a little practice I was able to drive quite a bit more effeciently and keep the exhaust temperature down. things like oil temperature and head temperature start with heat from combustion which can easily be measured with an exhuast temperature gauge. I am going to put one on my '61 bus next spring. |

I aim the IR gun at the engine block on either side of the crank pulley.
First I aim just left of the oil dipstick at the block, and then switch to the other side in the "corner" below the distributor. When things are working right, the temp runs from 195 to 205 F. We had three buses running from Philly/DC down to Bulli Brigade, and we were all within 5 degrees of each other.
I use this as a baseline temp, and if I see anything higher, I'll know something is wrong. But its real nice when you have some sort of mechanical difficulties to be able to check this real quick and rule out any cooling problems.
I chose the test point I just mentioned because it is the largest area of solid engine block available. If anyone has suggestions for other places to standardize on, I'm open to suggestion.
I bought mine at a electrical supply house for $99. I've seen them for as little as $69 since then.
Here's one like mine:

I've tested the IR gauge against a Gas Chromatograph oven, calibrated to NIST standards +- 0.2 deg. C. and the gauge consistently measures +- 1 Deg. C or approx. 2 Deg. F of the actual temp. This is consistent with the manufacturer's spec. for the gun.
I agree that a permanently mounted temp. gauge is superior, but if you don't have one, or want to compare temperatures from several buses at the same time, the IR gauge can't be beat! _________________ Founder and Chairman Emeritus, ECMSAS

To respond to Lind, I'd never heard of an exhaust temp gauge! That would definitely be an interesting way to check your temps. I never figured exhaust temps changed that dramatically when you're driving.

Well you guys never let me down. Thanks for shaking me out of my stupor. Sorry guys. No I won't do it your right it does look gay. I looked more closely at a bus that had them and I really don't like it.
but in my defense I would never drill holes do it...it already has the holes for it.
Anyways no scoops for me, except icecream. |
