Ach it worked faultlessly for 7000 miles.

The issue was to bleed it it takes two people.

One at the front to open and close the valve, One at the back with the hose jammed into the filler neck.

The guy who helped me never knew how the valve on my pre rad works.

If you close it and oush it past the point where it's closed it starts to open again.

So for 7000 miles it had been weeping.

I regularly checked it at least once a week but the weep was so tiny that it took 7000-8000 miles before it has weeped enough to cause an airlock.

All that aside the pre rad is now burst somewhere and is leaking so is now useless.

I fear the cold over winter is what's burst it.

I'd much rather have a setup that I didn't have a worry about.

If you check the ATS website you'll see they did 21 pulls back to back with no heatsoak.

That info is good enough for me but due to my stupid side feed inlet that core is just too big.

I physically couldn't get the pipework back on itself to meet the outlet of the core.

From the research I've done it seems that a larger surface area is better than a thicker core.

Also, Toyota themselves use this same setup on the same side on the supercharged MK1 and according to some members posts about this setup

(well one user in particular) the rsin tray off made zero difference to the rain tray being on.

The lack of any real world data on a smaller core than the ATS one is what puts me off, when I say smaller core the one i'm looking at is still more than twice the size of a greddy/spearco sidemount and actually just marginally smaller than the kit ATS sells but it is a different shape, Same shape as the one in the pic.

As for airflow you have the whole bottom of the car for upward airflow which is the natural flow of air for the mr2.

I'm certainly not trying to justify why these are better or worse but from what I've read the side vent has very little to do with these setups.

They also run fans constantly.

I may well just go boot mount.

Good news that my block's not cracked though haha.

Oh, Something I forgot to mention.

.

.With my CC system not working at all the CC core alone was enough to handle my low boost setting

(21psi 330whp) it was only on high boost it started acting up and misfiring etc then eventually bursting the head gasket.

Low boost was no issue at all whatsoever.

I run the car in low boost pretty much permanently.

Had I not switched to high boost I'd have never known.
