i am only going to say this because i know you are a 'function before looks'- guy  Grin

have you thought about a serpentine belt with tensioner and 2 pulleys for the fan… swapping that is easy and you don't need several belts and setups. maybe even make one that is reversible with one big end and one small side. it can be done with a tensioner.

Who does a set up like that for dry sump & type 1 alternator fitting?

That is to cool Mr Webb.
Hats off.

Venturi ring helps my engine about 5 degrees celcius on hours of highway cruising, for your info.
It is a ten minute pop rivet or spotweld job.

Have fun.


Thanks Eddie, real world feedback is always good Cool The claims on the webpage seem at little exagerated Wink I ordered one on thursday to try it anyway and see if it helps at all

I think that bottom pulley is to big to fit with a pauter pump, but have asked someone I know with one to measure it, it needs to be smaller than 120mm diameter ideally

that looks like a decent setup at a decent price.
 i was also thinking of a pulley in two parts like the original, but with different angles on the sides (front and backside). that way you turn them around and have the belt lay deeper then normal, but you'd need two belts and still the shims… not sure if this an option as the nut sits on the inside (short shaft). but it maybe could be made with some thouht put into it.

anyway good to see this topic back on top of my reading list.  Grin

If it gets too hot on the cruise section while towing Ritchie, then it might be time to get the "bush mechanic" repair skills a thought.

I've sometimes rigged up a windscreen washer bottle to feed a patio mister (or really fine-spray irrigation mister) into the cooling fan intake.
Knocks HEAPS of temp off as a last resort.........

Serious question - does it create steam? I'm guessing the quantity of water isn't that great but it's got to go somewhere!

I first used it in a Square in the tropics, and it still worked well there even with the humidity.
It was suggested to me by an old bloke to reduce temps just before they spiked hard and you had to stop, there were lots of old Volksies around there back then.
Dunno about steam, I never noticed any. I used it on Beetles that were already really hot and pulled over, and didn't notice any steam rising up there either.
I guess it's possible I spose, I've never thought about it for long coz you use so little water for such a short time that I didn't think it was an issue.

I tried something like this years ago, running air to water intercooler and figured out as I needed to empty it after a pass anyway why not before I got to pits, so had a small screen washer pump hooked up to water tank, then same principle with a jet aimed at fan in shroud and turned it on once on return road driving back to pits, not sure how much it cooled and didn't empty the thank enough so stopped doing it after a few goes

A big oil cooler with a electric fan, mounted in a good spot is what I would add to keep the temp down. Not sure what oil cooler you got on this car..?

It will have 2, at moment it has one "medium size" one but its a lot easier to add a 2nd one with the packaging issues I have with turbo/header etc in way. Just waiting on some fittings to arrive and will plumb it in  Smiley

Ah! a precision ~900hp capable turbo! Very nice! Not sure if you need that much hp, but it'll do fine I'am sure  Grin

I have put some miles on it this week, showed up a few holes in the map so worked on that and it drives pretty good now, also found the oil cooler wasn't getting enough air flow over it in stop go traffic so have moved it to hopefully a better place. With all the turbo/header/dry sump tank etc being above and around gearbox there isn't a lot of room to work with.
Still waiting on the Drag radials to come, was supposed to ship on 13th but now been told it will be another 2 weeks so will have to test it with the slicks next weekend, not to critical as still working on the boost part of mapping anyway
It does seem to get some attention driving around with quite a few comments and thumbs up Cool one particular car following me for a while, a Mazda MX5[Miata] with a whole catalogue of bolt on junk & stickers that looked like the wheels are falling off Roll Eyes  that keep coming along side and revving the engine to get my attention but just got ignored Wink
