Default How much timing? TR220 6.0 w/ 5# Radix 122.

Here's my timing table. I believe it's the one Magnuson includes. Where do I start? How much should I add and where should I add it? I use 93 octane. Thanks.

You'll just have to start adding timing in those lower cells little by little and scan the results. If you have no KR, then you can add a little more. Once you get to having repeatable KR, then back it off some.

I was able to run 18-19 with the 2.75" pulley on my LQ9. In the hot summer or with poor quality gas, I'd need to lower it 1-2*.

With only 5# of boost, as long as you don't have KR right now, you might jump to 20* and see how it responds.

I've got an extra 2.8" pulley and a gatorback bellt for it if you are interested in raising boost.

+1, thats the best way to do it IMO. Add a little at a time and watch for KR, and listen for actual knock. Once you start seeing KR then back it down a notch in that area.

Make sure your IAT table pulls timing once the air temps get up.

Oops its a 112 Radix, not a 122 if that matters.

Is the bottom row the WOT timing?

Thanks for the offer BigTex. PM me a price.

I'll add it like you guys said and see how it does at the track tonight.

Depends on how much air you are using at WO.

Oh, yeah, so does mine. I was just trying to give an idea to C.D. Homie that he might not be on the last line. But like you said, it depends. If you follow your MAP graph in scanner as it crosses 135 kPa, and look at the table, is your's also at 1.16 at that point, 03?

Well I was only able to run a 14 flat at 105mph. The track was so slippery that one Camaro hit the wall and about 3 other guys came within inches. They had just stripped and retextured it apparently. I was running 16.5 degrees with no knock. It could have been more, but I forgot to copy the numbers to the low octane table This was also on my 79# Tahoe wheels and tires, not even using first gear (launched in 2nd) and not going WOT until 55mph. I guess with all of those excuses I shouldn't be so disappointed. I know it has mid 12 second potential even on this slow track. Guess I'll try again in a couple months with the slicks.
