Go with the 25 row if you plan on ever seeing the track.

I ran my 19 row Setrab oil cooler from AAM Competition at the track in Alabama as part of Z Nationals last September and the temps that day were easily 100+F. On the track by noon was hotter and I never saw my oil temps over 200.

I've got the modshack 24 row true cool and it handles the track just fine. If I recall, I only had to cut a couple hoses and make a bracket, but it really wasn't any more work than buying a premade kit. However, one of my fittings failed and I hit a tire wall when I crashed, so that should be a consideration too.

Other than what I have with some 4000 psi hydraulic hoses now, I would just buy the Z1 kit.

I have this from GTM, not sure it was 19 or 25 row, but works perfectly in our weather

Guys, you can still peg a Z at 280F with a 19 row cooler on a hot day. It all depends on how you drive. If you're conservative on track and typically upshift early (don't keep the revs at 5k+), you won't have temp issues. If you're aggressive and downshift into second in corners and really dog it, you'll still spike your temps with a 19 row cooler. A 25 row does better, but some guys just go the 34 row route (best for F/I). If you have a 19row on a 100F day and only see 200F oil temps, you're driving very conservatively.

The beauty of the oil cooler is that your temps come down much faster when you ease off the throttle for a short period. You can have 240F temps and one easy lap will have you back at your thermostat plate temp.

Hell, I saw over 225 with my 34R on a day where it only hit about 50 degrees at Sebring. And this was only my first event. I can imagine when I'm pushing it harder and on a 95+ degree day I'll easily be over 240.

RCZ · 04-04-2011, 09:21 AM

FWIW. I had the Stillen 19 row and that was not enough to keep me comfortable on the track. Switched to a Jnaut hybrid and I haven't seen temps past 220 yet, but I haven't taken it to the track. For my next oil change I'm switching over to a GTM 34row cooler, they have the best price for the biggest core. GTM's 34 row cooler is listed as 13X2X10.25 = 266ci. The Z1 Cooler is listed as 13X1.25X10.25 = 166ci.

The question is...is GTM's core really that much bigger or is there a typo on their website. Can comment on this? GTM?

GTM uses the series 6 Setrab core which are all 2" thick. Z1 uses the series 6 Setrab core as well so it should also be 2" thick, I believe that is just a typo.

I have the 72 row series 1 and if I keep the RPM's above 5k continuously with lots of full throttle then the temperature slowly climbs to 260F after 30 minutes in high ambient temps. If you back off a hair then the temperature stabilizes, if you go up a gear for a lap then the temperature does drop a bit.

Yeah thats on me. I do not know where that number came from. Not to split hairs, but the ACTUAL width (as listed by Setrab) is 1.83".

Thanks for pointing that out guys

StealthZ....you must have the core laying on its side if you are running a 72 row?

Yes the AE kit (which we both have) provides a mounting bracket to lay the unit sideways.

Was this with the supercharger though?

Nope, bolt-ons.

I will add one more positive for the Z1 kit... no drilling is necessary. There is an optional top bracket (which is probably a good idea) that you have to drill for but otherwise you use existing holes to mount the cooler.

The reason to mount the cooler hoses up is so that the cooler doesn't drain into the oil pan and make your dipstick inaccurate.

flashburn · 04-04-2011, 09:46 AM

Yeah, true, but definitely don't skip drilling for the top bracket if you get the 34 row. They say it's optional (though recommended), but if you are going to be driving this car with any real intentions (i.e. putting that cooler to use!), then you should use that top bracket.
