i have a simple rule, i dont trust other peoples work.

My brother works for Pettit. He ran into the dude that installed my Profec B and informed him that I boost over 30 PSI because of his blunder. The dude started to laugh then realized he was the only one laughing. My brother told him he didn't think it was funny as its going to cost me over $3K to get the engine rebuilt. He stopped laughing pretty fast. I am waiting to see if he is a stand up guy and will offer something to compensate me. I know he will never touch my car. Onnly Pettit and Just Racing Fabrications will besides me.



Unfortunately I do not have a lot of time to work on my car. I am fortunate enough to be able to afford to get work done when I need it. Unfortunately that means of being able to pay for work on my car is the exact reason I have no time to work on it. I guess its a good tradeoff.

30 psi is a hell of a hit. if he was laughing the only reason he shut up is cuz he was shook, he probly wont do much. He should pay for the rebuild i'd be shooting ppl by now bro.

I am still trying to figure out how your boost controller decided to spike the boost? Most default to running the stock boost that the acctuator or wastegate were set for. I am thinking there is more of a hookup blunder than just wiring.

i took it as the controller was off

So, what's the word? How did the comp. test turn out?

the ******* that wired your boost controller to you windows should pay in full and up front.



second of all, you dont need a profec b with most motec's, which unit do you have?

TheCamel

with an electronic (in most cases) when the unit is turned off, the system defaults to the original boost, which means either the stock acctuator or the wastegate on the turbo will go to their normal set boost levels. For instance if the unit is set to boost 14.7 psi (1.0 kilo) then the unit it switched off and stock boost was 8 psi (0.6) then the car would only boost to the spring pressure inside the acctuator or wastegate. All a boost controller does is fool the acctuator or wastegate that there is not as much pressure in the system, on an electronic module the solenoid is in a normally closed position. Boost lines flow just like the factory. When the boost controller is engaged the solenoid vents some of the pressure to the atmosphere.



IMO one of two things happened, the boost pressure either blew a line, or the boost controller solenoid is stuck open.



Logic: If manufactuers would allow the boost control to spike like that, why would they put a power switch on the unit?

I am not having a good week and I am ready to rip peoples heads off. I dropped my car to my normal RX-7 guru mechanic 2 weeks ago to get the rear end rebuilt. I was doing it as a preventative measure it was making some noise so I decided to order all the parts I need from Mazdaspeed and have it rebuilt. I still do not have it over 2 weeks later. The car is up in the air on jack stands with the rear out of it.



I want to trailer it down to Pettit's and have Cameron take a look at it. This guy can tell if an engine is going to blow just by listening to it. He is amazing. We are also going to hook it up to a Mazda Compression tester and see whats up. See if the engine is weak or cool. I am hoping its o.k. but might not know for sure until tomarrow or Friday.

I agree camel. There is someting really wrong with my setup and I am going to have Cameron look at that too. I am going to call my Motec rep and see about boost control. I remember when I was buying my M-4 he asked me what I was using for control and I told him the Profec B and he said it was ecellent and to just continue to use it.
