Harness definitely not well suited to a sand car mounting, but I cot it to fit . i ended up using the I/o more than I thought 1) I didn’t want the fans to turn on with ignition so I used I/o to stagger the fans by 5 deg and leave them off until engine was at 800rpm. 2) datalog switch 3)...

I’m also entertained by the concern about 1 big turbo vs. 2 smaller ones. I mean, it’s just math. 4 cyl feeding 1 properly sized turbo… or 8 cyl feeding a 2x bigger turbo is the same thing. LOL. Yes, it takes more pressure and flow to move the bigger turbo, but you have more pressure and flow...

Holley with a flex sensor is super easy. Adjusts timing and injector pulse on the fly. Haven’t done it yet on my car but have done the homework. Need enough pump and injector to manage the range.

1% horsepower loss per 10deg increase in IAT… or 1% gain for every 10deg IAT reduced… make it cold

I have a 16x6x3 intercooler (supercharged) that gets some air pulled through it by the radiator. Without fans it can’t keep up, 120+ IAT. With fans <95 IAT.

Since it is loose, bearings will be chewed up. New bearings and 3/4” breaker bar with a jack handle and your biggest buddy.

ChatGPt version

Asking ChatGPt now. I think it’s a little tone def. “Your table gives it 16°, which is extremely retarded for that load and RPM.”

Here’s my actual table. Slightly more conservative than yours I think. I’m looking to get more pull in the midrange… which is what I asked Grok to do :) I’m just using different units than you, psi vs. kpa

Yeah, seems like 32deg is a bit aggressive. But maybe my 24.5 isn’t quite aggressive enough.

I found an ignition short to chassis on my old VW rail with something more sensitive than my finger…. 🍆

Messing around with Grok last night and asked for an ignition table for an LS3 with an LSA supercharger and 9psi boost. Using 100 octane. What do you think of th

Car was running rough all of a sudden. Idle was clean, mid-rpm was clean but off idle and lugging felt like it was missing. Pulled the Holley data logs. Couldn’t see anything suspect. All the ECU connectors were tight Hmm, what else could it be? LOL

Do you have 12V to the Mefi? If you switch the ign on and the fuel pump doesn’t run… that indicates the ecu isn’t powering up

Air to air in the back of a buggy can be pretty inefficient. You need airflow to make them work at peak efficiency. It will be better than nothing but certainly not ideal. Keeping it away from motor and exhaust heat is critical. I wouldn’t mount it the way the Subarus do. All that engine heat is...
