2 days of rain have made the blacktop black - hopefully it stays this way until ..........forever (wishful thinking.)
Took the car out for a minor shakedown and to burn in the EBC front pads. I wanted to lean on it hard, but.........I'm old, cautious, nervous..........ok, maybe old, but not the other two
The EBC yellow front pads after getting properly broken in - yup, the car now stops with manual brakes comfortably from 100+. Thanks Dave for the manual conversion!!
I upgraded the Holley software to V2 to be ready for the IO box software (yes I bought one of the 554-165 boxes), and also to have Holley data for the Bosch 210's. The software upgrade went OK (thanks Duke for some guidance), but the injector data swap basically put me at square one with the tune in terms of keeping the rods in the block and straight. So the idea of leaning on it hard went away. I dropped out some timing and worked at getting the fuel table safe. I succeeded in safe, but not anywhere close to maximum the amount of 'street go'.
I put it to 20 psi a couple of times with the timing in the tank and the AFR fat enough that could see a cloud of unburnt fuel smoke behind me. I saved the datalogs from the two hits and I'm working on them from there. I measured success in driving it home with all rods, bearings and block in tact. After approx 25 miles of driving it on the highway the pump gas driving tune is pretty clean - thank you Holley!! It's insane how fast this system will learn. For a naturally aspirated build this is crazy safe and easy. The atmosphere and a half of pressure is the only thing making it a little tricky, but not too tricky.
I put on the summer tires, MT ET street 255/50R15's and I experienced a minor amount of vibration on one 10-15psi blast. I'm attributing it to never changing the pinion angle after dropping the rear with spring upgrade that I did over the winter that dropped the rear about 1 1/2". The pinion angle presently is about 4 degrees negative (down) from the transmission. 3-5 degrees is what all of the experts recommend, but I've always set everything in the -1 to 0 zero range and never had an issue. The 5409 springs are shorter but a faster spring rate (stiffer). I'm not sure which of those is contributing and I'm sure the fine shock package I have (rusty blue no namer's) isn't contributing :-0 (sarcasm) . I'm going to reset the pinion angle to -1 to 0 zero and see if it has any effect and go from there. I have access to a good set of Bilsteins if the pinion angle change doesn't resolve it.
Hoping for the weather to hold, swap it to straight E85 (E70) and play with the boost control to see what I can break this weekend.
