I needed to know if I would be in danger of blowing my motor. I have a supra with bleeder valve mod, downpipe, intake, and 12 volt mod. I can't hook first and second gear. I am scared to floor my car because I don't want to blow my motor. I was pushing 18 psi with just the bleeder valve mod, on a warm day. Does anyone think I will blow my motor.

Ditch the bleeder T and go with some other form of boost control (maybe a manual boost controller or EBC). I assume you have a boost gauge since you know the boost level. You may want to invest in an EGT gauge if you are really worried about going lean and blowing the motor. Change your fuel filter. Good maintenance always helps.

I think it is possible to blow a Supra motor at BPU levels. All it takes is dirty fuel injectors and high boost and all of a sudden you run out of fuel and have too much air. Just make sure you take good care of the car.

I have a friend who has a BPU+ (Front mount intercooler) Supra and when he dynoed it he found it was running too lean during high boost. The Supra he owns does not appear to have been well taken car of by the previous owner and although I did not find out the cause of the problem I am pretty sure it has to do somewhere with the fuel system.

*edit* I have heard conflicting things about the 12v fuel pump mod so i don't really want to comment on that. From my reading I have learned the stock Supra fuel pump is supposedly good for 500rwhp, which is more than any BPU Supra will put out. I think injector condition is the area that is probably least paid attention to on Supras. Injectors can be pulled and sent out to a company like RC engineering and brought back to good shape. Tha info was something Jack B posted a while ago which i thought was good advice. Enough babbling. :)

How to check out if injectors or fuel pressure regulator are bad?
