Alright so I've just about done anything possible to figure out why my car will not run to its full potential. Let's try to stay on target.
so what is your guess?

Alright so I've just about done anything possible to figure out why my car will not run to its full potential. Let's try to stay on target.
so what is your guess?
06-09-2015
Zero boost? None at all?
06-09-2015
The most I have seen in a while is 5psi that was a while ago. This evening it was 1.0 and on a from a start run to 90 mph was .5 psi..... With the bypass locked shut.

Bad boost gauges?
06-09-2015
Oh. I was gonna say just run 1 vacuum line to the top of the bbv and remove the lower - so it's based off vacuum alone
06-09-2015
No belt on blower? You some how routed it so it spins backwards?
I think I made more boost than you when I was n/a.
06-09-2015
Map (T app) and mechanical both read the same.

Boost leak? what's the SC gasket look like? Somehow the LIM or SC are warped and boost be leaking from the mating surface?
06-09-2015
Spun a bearing in the rotor pack?? Never heard that happen, but I guess its plausible.
No strange noises of any kind?
06-09-2015
no weird noises. The only time I have ever seen this was when the driveshaft stripped from the drive end for the coupler.Originally Posted by bandook

Gasket was maybe bad. Both surfaces are under .005" using feeler gauges. RTV'dit back on last weekend. No change.

Wait, are we guessing because you know what the answer is, or are we helping you sleuth this?

Blue RTV, had a friend set the blower within 15 minutes and torqued the bolts in sequence at half the torque value then back to the full 17 ft/lbs. Waited 5 then ran around them again. Sat for 5 hours while I installed everything in place and waited. Then put the belt on and went for a drive.

i would say large vac leak

You RTV'd it right? Black, red, gray or Honda? Also did you let it cure a little before putting the mating surfaces together? Also how soon did you drive after putting the SC back on with the RTV? If it did not fully cure before use you might have blown out some RTV. Done this on an exhaust before.

I don't fully know the answer but I am suspecting the driveshaft to coupler drive is toast.
So your helping me sleuth this too. I've replaced everything from the PCM to MAF to baro and MAP sensors along with all the other vacuum leak tests.
06-09-2015
what are you using to read boost what are you using to scan? what has changed since it last worked properly? lets all keep taking a shot in the dark and guess since the op hasn't given enough info.....

He already said his mechanical gauge reads the same as torque pro...
And he actually helps others on the forum so I don't mind helping him brain storm.
06-09-2015
I mi have posted more information on this car and everything that I have done for the last 2 months I will link them here in a minute. There are charts and graphs and they never get a response.
if you had read any of this it already states what I am using to read boost. The Torque app and a mechanical gauge.

So lesson number 1 here STICK WITH SAME THREAD SO PEOPLE DONT HAVE TO SEARCH MULTIPLE THREADS... this thread is on page 1.........
