Whistle me a tune

Well still trying to get the tune right on this thing...I had a big lean spot right at the hit. I swapped the accelerator pump cams out and took care of most if it...I think I'm still gonna have to go up a size in squirters...but getting there.

MSD - Missing Serviceable Diagrams

So, I recently purchased a second MSD Boost Timing Master because I couldn't get the first to work and since it was used from eBay I just assumed it was bad. So, today I hooked up number two...same thing! It would fire but not run...so I was now suspecting a wiring issue so after much googling I stumbled upon a post for a different MSD box. HEI's that use the 4-pin module must remove the module and wire the magnetic pickup into the MSD box! Mutha-F! Hey MSD this might be something helpful to include in your instructions...or the special addendum you put out specifically for the 5462 when used with an HEI. Anyway, I went back out removed the module wired in to the green/violet of the MSD...turned the key and ta-da! A working Boost box.

Test-o-matic

I needed a way to test my homemade boost referenced power valve...so I built the "power valve test-o-matic" it has a tire valve, a nipple to attach to the boost gauge. The power valve screws in the bottom. Fill it with some water attach a bike pump and boost gauge and ta-da...I can see at what psi the valve opens...when the water starts passing through the valve.

Pullin' hard

Well I did some mucking with the truck the other day trying to get rid of the sluggishness down low...so I added some more timing to the mix and it was what the doctor ordered. Is is pretty good down low and pulls hard under boost. Now I need to put the boost ref PV back in and hook up the laptop and see where the A/F is - Posted using BlogPress from my iPhone
