[urq] Dialynx rad vs Stock rad w/ Aux rad delete

[Maurits Jonkergouw]

Recently my main rad has gone bad (amongst other things) and needs to be replaced. The aux rad was deleted a long time ago (also leaked) and never noticed increasing water/engine temps, not even during high speed travelling in summer. Although I have to say during this hot summer my exhaust manifold cracked at several places, but that's just coincidence :-)

So, do we really need the aux rad? IIRC my water temp only went from 1 bar 'below normal' to 'normal', but I must say this was with a very inefficient turbo.

But what if the turbo is back up to spec again (after rebuild), what if the exhaust manifold is replaced with the performance Dialynx EM? More performance is more heat.

I was looking at the high capacity rad from Dialynx but it's not cheap. I do have a good stock 48cm main rad from a CoupeQ but it lacks the extra aux rad header. I've read in the archives a few people had no problems what so ever removing their aux rad while keeping the stock rad.

What do you think, is it safe to delete the aux rad and keeping the stock rad considering a Dialynx EM and rebuild turbo will be fit ???

To be honest with you, I need to cut some repairs in order to save money. If the aux rad could be removed while keeping the stock rad, this would be a major cost-saver.
