ghetto rig a wastegate to open at like 5psi

Here's an idea, If you trust your brother with your car while he's sober, I'd let him take it to the actual prom. When he's done he can bring it back and take his own car to go party.....at least you won't have your car to worry about, only your brother.

I have done this before with my brother and to test the effectiveness of the waste gate.

Just disconnect the wastegate actuator shaft from the wastegate lever. There is a single E-clip holding it on. This will cut all boost in 1st and 2nd gear. Full throttle 3rd gear pulls will only net ~3psi. If you have a way to richen up the fuel that will only do so much and might also car the car to flood upon restart. Also disconnect the secondary throttle plates.

Any combination of these will severly limit any power the car has. But as with easy driving he will still build up enough speed to severly damage the car. You can damage the car going virtually any speed (curbs). If you are that worried just do not let him borrow the car. Also try taking him out before and let him try the car out w/you in it. that way he will not be suprised with the power.

is the engine locked ? if it is might be a stuck apex seal.

I'll be the first to admit that I dont know what I'm talking about here.. but cant you just take the turbo off your intake? Vent the turbo outlet to vent to the atmosphere and put your filter directly to your intake.. Tada... You now have a very loud N/A that sounds like your draining an air compressor.

Make a thin metal plate the same size as your exhaust gasket. Then drill small holes in it, only enough to boost 1psi.

Actually, the engine turns easily and I think a seal on the front rotor has either broken or become stuck. I pulled the plugs yesterday to do the ATF trick and there was gas and heavy buildup on the front trailing plug . When I turned the engine over with some ATF in there (socket wrench on Alt. Pulley) it definitely had just one "pulse". When I turned the engine over with the ATF in the rear rotor it made the healthy "POOOOSH-POOOOSH-POOOOOSH" noise...the front just did one "POOOOSH" . Anyways, I'm going to start it today and if the ATF doesn't miraculously fix my engine, I'm going to start pulling it. I'm kinda looking forward to doing this, as I figure if I can pull an engine (and I know I can) then I can pretty much fix anything on my car or most other cars.

Plus, I'll have a neato rotor paperweight and fresh engine for all my troubles.

yeah the "POOOSH" test is a good one. on the bright side you will have more power and a fresh engine i got a ride in a 88 T2 with street port and HKS alphabet of upgrades, t04e,fcon,evc,fmic, etc. that thing tried to lift the front tires when the boost came on. i was real impressed

I've thought about forcing the wastegate open before.. I think it would be a good idea for letting the turbo cool down, as well as letting the engine warm up.. Like, you're coming home...you get to your neighborhood, flip some magic switch, and ta-da...no more (at least, not much more..since you're going to be gentle anyway) boost!

Or..you start your car up... running late, can't let it warm up properly.. at least now you won't boost while it's cold..

or something..

of course, building some crazy actuator device to do this is another story..

i am pretty sure that the only way to "turn off" a turbocharger is by using an external wastegate, which would allow you to fully adjust the boost from 0 - infinity. basically youd be boosting at like 0 psi, and letting all the exhaust gas right back out to the exhaust and not to spool the turbocharger...

correct me if im gay.. ermm wrong..lol

Heres and idea, give him 30 bucks and go rent him a base model mustang convertable. That way if he does wreck something, it will be nothing of a loss.

hey, i just ran across this post while looking for something else... might be a day late and a dollar short, but, why don't you extend the throttle stop so he can't go to wide open throttle? Say about 1/2 throttle should take all the fun out of it

RX-7Impreza

there was a porche race car that had adjustable boost and the driver could screw a **** to go from 290 hp to 650hp. i dont remember what it was. prolly a wastegate, (I dont know all the turbo terminology)

Just pull EGI fuse and say it's "broken."

Blake_AE

Your mom's got an Audi A6 and he wants the 7? For the prom???

Seriously, and I LOVE my 7... it ain't a prom car. I'd have the A6 so damn spotless and waxed people would fall into it. Thats not even a question. Take the Audi... if his mother lets him.

RETed

There's is no way to turn the boost OFF, per se, short of redoing the intake piping to bypass the turbo itself.

If you have a stand-alone, that's real easy.

put some fishing sinkers on the throttle cable?
Hey Zach where ya been man? I want a ride in that ported monster!

adamlewis

Just make the WG stay open. If your car normally gets creep, you might see SOME boost...but it would be very little. If youve ported your WG, or you dont get creep, It probably wont see any boost at all.
