dunno, to make it quieter?

I have a 94 gas tank in my garage, I'll eventually install it and remount the pump. 90-93 gas tank is the worst (1.6 lol)

Vibration and noise dampening.

Car runs good but sputters a bit at >20psi. Turbo speed looks normal so I'm guessing I just need to tighten all the clamps and zip-tie every vacuum line. Battery voltage also looks a little bit low, not quite sure why. Finally, valve cover gasket seeps oil after boost. Its minimal but annoying - I have some 10.9 grade bolts coming in, so I'll just tighten it s'more

So Gay! no DW?

I like the little sock. Oh, you got the e-85 one, fancy connector and all that. I'm curious how loud it is....

Sock is from Walbro Miata kit for 255 pump. Fits perfectly. No DW because it doesn't support my goals on e85. I'm sure it died because I pushed it past its limits.

Well I fixed the fluttering issue. I forgot to tighten down the compressor housing v-band, woops

Now I have another issue. I think I'm lifting the head starting at 20psi or so. During a pull, past 4000rpm it makes a cracking sound , kind of like machine gun, and there is a smell of exhaust. I haven't looked further than that but I think I need to check head stud torque...

I did a run on just wastegate, for fun. Sorry for vertical video


And virtual dyno:

Blue line is with cracking noises, red is wastegate. Red corresponds to the video above. Obviously blue line should more (look at the torque)

I'm sure there are plenty of empty straight highways in Chicago, have you tried checking at 4am? If I can street tune in VA then anyone can.

5th gear realistically tops out at 120. Both my tach and speedo are inaccurate

My MS knows how fast I am going. More of a long term project is to get the OEM speedo to show the right number.

What's wrong with the tach? The OEM non-linearity of it, or something more?

I was going to say something clever about them never finding the blue car they saw race by, but I'm too drunk to pull of something so Einsteinian.

Think its the head lifting, and not something on the Manifold/turbo/exhaust???

I've had a lot of heads lift. Where's the oil? Should be plenty of leaks. :-) Have a leak-down tester and a decent sized air compressor? Might learn something.

Head lifting was false alarm. Its something else.

Oil is perfect, coolant is perfect, there are no oil leaks. Plugs were all gapped between 0.032-0.035, i made them all 0.035. One plug wire wasn't fully seated on the spark plug so that was probably the most likely issue. AFR wasn't affected though like it would if it was not firing.. but who knows.

Finishing installing this tonight:

This is not a very good comparison, but unfortunately, all I got.
Same tune, same settings, same fuel. No boost control, just wastegate. Different ambient temperature (blue line was 10* hotter). There was, what I now determined, some spark blow out, which kind of throws this comparison out of the window.

But still every log I have shows flat top to be faster.

So green is the 99-00 and blue is the flattop? Not bad. Gains abaove 5500 as expected. I wonder if at 400 it will be much more drastic

probably not

But this has me wondering: what do people do when they want to go higher boost?
We already know the limit for toyota cops is like 21psi on e85.
Apparently 25 or whatever you're maxed out at is the limit for gm coils?
Or do you think you're having a malfunction?
