How thin can you make a front mount radiator and its still be man enough for the job:)

This rad is the same hight, same number of rows and same width as an MPi rad, but is almost another 50% longer. Cosidering people are using the standard MPi rad at around 140 bananas, im sure this will be more than adequate for 200, after all, how often does the engine run at full power.

End tanks modified and a gentel curve massaged into it so that it fits snug against the front panel with no gap It is no wider than 27mm at the tanks. Its now a double pass wich should also increase the capacity, only thing that might cause an issue is the pressure drop across it

Its off to be tigged up

I was going to say pics please!

After driving mine the other day, I don't think I could get away with a smaller rad than I have (Fiat cinquecento). Are you thinking of using it just for the N/A engine or keep it for when its blown aswell?

1/4mile in 13.2sec @ 111 terminal on 15psi

So this isn't an MPi rad then? I don't get it - or are you just telling us what it isn't rather than what it is???
LOL

Why double-pass on that lenght?

As regards the MPi rad working / not working A mate of mine had an MPi rad on his Vauxhall XE mini, and it never even got a whisper of hot. Folks have tried them on Vtecs and they are pants.

I still reckon the smallest rad to get the job done for the intended application / climate is adequate - anything else is overkill (IMO of course)!

so what is the core? I recall Jimbo telling me the Miglias are using a BMW rad or somet nowadays.

Iys surprising how much extra space you get from curving the rad. Gav did this on his speedster a few years ago and it overcome allsorts of problems. Nice job

Paul

I seriously doubt it!

how many time has that toungstone touched down, lol.

Dave, it is not an MPi rad, i was mearly relating to the MPi rad for size, as it is the same dimentions all except the length.

The core is from a Vauxhal Nova 1.4. Double pass as both inlet and outlet at the same end, again saving space on plumbing, with the added benefit of increasing capacity, maybe at the expense of increasing pressure drop. I dont thinnk that will casue me any issues though with a full flow bypass therrmostat and leccy pump. I read that the OEMs theory on cooling system is that there should be at least 25% extra capacity in the rad at the most arduous conditions, rather than it just being enough at the best of times. This is for the out of ordinary conditions as well as fouling of the rad internaly and externaly.

You only have to look at the metro rad for the same engine and you can see the size that is roughly required. Yes you can get away with the smaller rad, but you are consuming the reserve capacity with nothing to spare. One other reason im using a larger rad is i intennd running lean burn at part throttle, which anotther reason for the oil jets i fitted on an NA engine. Method behind the madness :) My engine is different in many ways from every one elses, i have concentrated in areas other than outright power

Paul, thanks mate, but my fabrication skills dont come anywhere near yours im afraid I only bought the ally mig wire yesterday just to tack this together and its real ugly stuff. I think it will look better whan i get it back :)

Rad now mounted on the front panel, made a start on the rest of the cooling system. fitted the bypass thermostat, made a bracket for the header tank and ugly MIG'd them together, made up an adapter for the water pump inlet again ugly MIG

Everything looking good so far. need to make a mounting bracket for the water pump and another adapter for the water pump outlet then all i need are a few simple hoses and the cooling system is done

The only problem now is the bulky pre engaged starter motor

That steel front end looks good now Col. I see you painted all the bulkhead as well

Back once again like a renegade master

Hi,
Looking good in there, just needs an injun
Cheers,
Gavin :)

My Mini build diary

now that does look nice, but whats wrong with a side mounted rad?

Nice job, you say the core is a Corsa 1.4 but is it a pucker after market ally core or just a replacemant part you've moded, s I'm now in the market to replace my slightly damaged one

http://i28.photobucket.com/albums/c248/spe...er1/mini007.jpg

If it a'nt broke don't fix it !!!!!!!!!!!!!!!!!!!!!

Jordan, Yeh, that steel front is way better :) and the bulkhead needed a little tidying up. Doubt it will stay clean for long

Shed, its personal prefference I supose. Question for you, why do all the Miglias run a front mount rad?

Gavin, its a Nova rad, not the Corsa. Its a Nissens YB63287A replacement part. http://www.radicool.co.uk/vauxhall/nova.htm though the rad was a little cheaper than that when i bought it im sure. Obviously the flanges (he he) need reworking abit, and there are a couple of areas where its started to crack a little where i never anealed it properly, but it doesnt leak, which is all that matters to me. The other option is to buy a core from Pace http://www.paceproducts.co.uk/public_html/...php?productID=7 but you may already know this

Nice stuff - I wasn't trying to sound arsey, sorry if it came across that way!

So this is a nat-asp build is it? Did I imagine that you were going to do a turbo 16v?

I spy a nice thermostat as well. I recall the old SD1 2000cc had a smiliar looking unit - think it was a pressed, rather than cast housing though.

No worries Dave, it wasnt taken as being arsey

Yeh, nat asp for now, see how everybody else gets on, looks like its external wastegate teratory :) I designed the build of this engine around being able to easily change to turbo by swapping out the pistons and running the standard K gasket. In doing this I can achieve a CR of 11:1 NA and 8.7:1 turbo :)

I have in the last week actualy been considering Nitrous It saves all the space issues but we shall see. Just got to sort out the base maps and work on getting the COPs right :) What was the concensus of Nitrous in roadgoing classes at Avon, class B particularly

The stat is actualy from a TVR, but there are a few knocking about of different shapes if you know where to look

Dave, just make sure you know where your roots are and dont get too Americanised, I bet you have an accent already : Any jobs going?

very tidy

can i ask what size the outlets are on that stat?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

35mm inlet, 25mm bypass, 35mm outlet.

A little on the big size for what I wanted but the 25mm bypass was what sold it for me. You try and find a silicon equal 'T'

No, not got an accent - but I do find myself saying a-loo-min-um instead of aluminium because it's a lot easier than stopping halfway through a presentation because everyone wants to have a giggle at the strange way you speak.

There are lots of Jobs... User brocky has just moved over here; talk about the right time to move to the USA: House prices here are at the lowest they've been in years, and UK houses are still selling for way more than they were when 99/9% of the population purchased their house...

I have no regrets - other than missing out on friends and having a local boozer. LOL

Everything is now in except the fan, which needs a little trimming of the cowling, but it will just fit.

The bonnet still fouls the head. The bonnet needs another 10mm to fully close, so it looks like i will still have to cut the cross brace, even though I was hoping to get it all in under a standard bonnet, Hey Ho.

Theres about 10mm between the alternator and rad, and about 5mm between starter motor and rad and thees 5mm between exhaust manifold and bulkhead. so it is a little tight, but not as tight as another I have seen

Bloody hell that just fits. Well done for getting it all in.

I presume that its all solid mounted to.?

Si

I drill holes in everything..!

Hum,

Are Maniflow now doing manifolds for K heads, or did you chop up a couple of LCBs & fabricate you own manifold?

commisioned by SC i think rob
