I'm guessing too much drag. Did you have your arm out the window?

Took it for a drive today after the new plugs. I guess I didn't pay attention to boost in 3rd-4th gear before. Boost is set to 15psi, and it hits that in 1-2, but in 3rd and 4th all I can get is 12 psi. Would this indicate a boost leak?

I ran a 111mph and a 12.9 spinning all the way from the start line through 3rd. Theres got to be somehting wrong. Your definitly missing power.

I would check compression. I have never used 3mm seals, but I have been told they can wear on the rotor housing pretty quickly. Just an idea...



Also some soapy water, rubber pipe cap form home depot, and a fitting makes an awsome $3 pressure tester for boost leaks.

Sounds like a boost leak
kan made 423 on 16psi w/ my car and it was doing 120-121mph
The 9's are not bad plugs you just have to clean them all the time. Driving around town on them will foul them real quick.
Also do a compression check just in case.

Hope ya figure it out!

I'm going to attempt to make my own boost leak tester tommorow. Should I test it at the compressor inlet?

I gotta fix this thing. I can't be rolling around with 275-300 whp.

Start the car and spray carb cleaner around the intercooler and piping if you get a low idle you got a leak.

I tried ether already but didn't get silly with it in fear or burning my face off.

What are the chances of my leading coils night firing? Above picture shows the bottom leading plugs pretty black and shitty. Leading is ran off TII and Msd 6A. Hmmm

If your leading coil isn't working the car will barely idle. You'd know it.
