Another thought is meth/water injection and/or the a/c boost freeze chiller system that weapon x has. I guess they both really only address intake air temps whereas the triple x heat exchanger addresses coolant temps. They’re related I suppose though.

I don’t know if it can run at 100% duty cycle though. I’m waiting to see who plays with it on track first.

Meth seems like kind of a pain although it also adds power via fuel supplement. I don't really want yet even more power though. Priority is to make it reliable and easy. The chiller seems like a good idea for IAT. And the triple X heat exchanger for coolant temps. Maybe an oil cooler too although I haven't heard oil temps get terribly high. I'm tempted to try just the heat exchangers for now since I need to take the front fascia off for the super charger anyway. Then add the boost freeze if things don't look good. And then the oil cooler last if necessary.
Does redline water wetter or other specific coolant tricks work? |

I would prioritize the oil cooler. My oil temps got really high on track with the Whipple/Whipple calibration/stock otherwise. It got up to about 290.
I’d do that ahead of upgrading the radiators.

Oh that’s good to know. Where were the temps after the mishimoto? Curious to know if that’s good enough vs trying to do something custom.

Do you think cooking your cats was based on the tune primarily? Was it running rich so it could have more timing before knock? I wonder if a tuner could tune for reliability vs power. I’d happily give up some hp for cooler temps and less risk of breaking stuff. |

My oil temps look more like ZL1 temps now, which is that they get to 270 and stay around there. That's a perfectly sustainable temp for oil on track.

Any noticeable changes in handling due to the extra weight up front?

I found out that the weapon X triple X heat exchangers are not compatible with the SS 1LE. But I did find these from mishimoto.
https://www.mishimoto.com/chevy-cama...tors-2016.html They claim 8 degrees cooler vs stock. That's not a ton, but better than nothing I suppose. And they're not nearly as much money of course. So I might try starting with these and the oil cooler first and see how it goes. I also found this one from C&R: https://www.crracing.com/product/che...l-transmission It's $1200 though... and it's not clear how it might fit or not with the whipple stuff. So I'll hold off on that one for now! |

ChrisV - Do you think you’ll end up cooking your cats again or will the changes you’ve made prevent that from happening again? My local tuner is strongly advising against FI for road track use as he believes I’ll keep cooking cats. Even with a custom tune.

I have both green cats and catless, but I’m going to stick to catless on track. The green cats should be able to handle it, but why chance it? For autocross/drag racing where you’re not doing 20 minutes at a time, cats should be fine.

Yah. I’d like to stay catted since it’s my DD and dealing with smog in CA is a pain too. I’ve never heard of green cats so maybe I’ll check those out. Or I may just abandon the FI route entirely. Save the money for a used C8 Z06 when they come down in price a bit!

Quick update. Still going back and forth. My tuner is pushing to stay NA. Whipple and the seller are less concerned about breaking stuff. Stories of burnt cats and broken pistons notwithstanding, I'm also looking at doing a powertrain warranty to make me feel better about it at minimum.

I don't know that you're going to find a powertrain warranty on a built motor though.
