Hey, you going to Dr. Ho's Dorifto Day tomorrow? I just put on some craptacular tires for it!

I haven't ditched it, but I was getting a high speed miss about 15m after I installed it. I couldn't figure it out, I thought it was the in-tank fuel filter because it happened after a long sweeping right had turn at almost WOT.

It turns out my AFM went bad. Now, I don't know if it's because I mounted it on it's side and facing downward, or if by handling it so much test fitting the CAI knocked something out of whack, but it took a dump on me. We replaced it with Dana's, and put on his Apexi intake for dyno purposes.

When I get a replacement AFM I will mount it pointing down towards the CAI, but I won't turn it on it's side.

If it goes bad again, then I know the stock AFM doesn't like pointing downwards.

And...you had to ask. *grin*

I LOVED when I put my S-AFC in my N/A... totally changed the midrange. I probably gained 5 hp up top, but probably 15 at 4000!
Really woke it up.

Only depressiing part about N/A's is all the money you dump in, and the little results that come from it. Dump all that money into a turbo and what do you get? Ahh well, my GTUs is still staying N/a, for now until it pisses me off

Yeah, but you get reliability. My car made it 215k on the original engine. For the 30k, or so, it was being road raced quite a bit. The final straw on it was actually a broken fan clutch and a stuck termostat. It was still going strong until then. I'd like to see someone with a turbo last that long.

my 85 GSL w/ 148k miles on original engine just pulled 7.8, 7.7, and 7.9 at 171RPM on a mazda compression tester
those sorta numbers are good, but that was at 171RPM, if I was cranking at 250RPM they would've been through the roof.
P.S. that was front rotor only cause the tester fitting wouldnt fit between the steering knuckle and the rear rotor
