I wish mine could be set at rpm instead off boost level.

Meth just flows off a pump. Find some other device to trigger the meth relay. It's pretty simple. You could probably wire up a nitrous window controller to do just that.

I think it was super chevy magazine that did a drop in piston LT1 and they change the bolts to ARP.

What kit? With certain kits you can set the activation PSI for the pump. Set that about 4k rpm boost levels. However, I am curious to see why you see such a loss at activation. Is the system progressive? Are you flooding the motor out? Too little timing?

Bleed off boost with AFR. AEM makes a failsafe gauge. I've never used it, so it could be crap. But its an option.

This would work.

I had TSP look for a set for me and they said they weren't out yet. That they couldn't find any.

Pray, I saw vengeance on this forum has drop in pistons also, I assumed that was with rods and bolts. May be worth checking.

What you want is an AEM Fail safe gauge or something of the like. It has programable failure states and data logging, which include high flow but no pressure (line popping off), low flow high pressure (something clogging the line) and everything in between. This can be used to send out a voltage signal to other devices to cut boost on a turbo car.

For a blower car I think the best bet is to figure out a way to cut ignition. I've seen on a forum somewhere, someone claimed they had a fail safe that cut ignition. I'm not sure what could do this really. But where there's a will there's a way.

That was kind of my point. I read people say "your tuner will build in fail safes into your tune" I just don't see how with the current ECM technology with a blower. Unless you are running a waste gate there is no way to cut boost. Even if you cut timing, the car is still lean and still making boost. You can't set up some sort of over fueling strategy if you don't have the fuel available. I guess if you had a capable fuel system and purposefully leaned the car out to rely on meth then you could do it. But most guys run meth cuz they don't want to sped the ridiculous amount of money on the correct fuel systems for these cars. Like I said, I may just not know what I am doing. So for now, I will shoot for 12.5 at the leanest on pump and put in the meth for 12.0 and get out of it what I can. If it fails then 12.5 is plenty safe for a pull.

You, of all people, can figure out a solution to this.

Let it sit. Just stay open minded to part combinations, and in some time you'll figure out a way to make it happen.


The engine is a pump. We control the air, the fuel, and the spark. We can tell it to shut off whenever we want. Maybe that's the solution. Something in the programming of HPT. I don't know the GUI, but I'm sure there's somewhere under X load, or X maf voltage at X load. I don't know if it's a maf using alpha n, or a map/temperature VE.... But you can trick the sensors pretty easily. Sensors are made pretty simple. It's ultimately just a circuit.

Same with boost pipes. I think someone else in here brought it up: wastegate on the intake line can let you drop the PSI. You could even use a chinese wastegate; the temperature a chinese wastgate has valve issues in terms of actuation are so high and extreme compared to intake temps. Spend $60 on the proto type. Keep all boost at a completely sane level, af/r's safe. See if you can get it to dump on command.

There are solutions here.


The internet should be a place where we should come together to help solve problems. Otherwise what are we really doing on the computer?

I have an aftermarket stand beside ecm that offers virtually unlimited flexibility. What ever you can dream up it can do. That being said what I am doing as a fail safe could be done without the extra ecm. I have my ecm set up to open a pair of relays that apply power to the factory coils. if I am above xxxkpa and above xxlambda on the wideband it will cut power to the coils. This could be done with a boost switch and a voltage switch hooked to the wideband.

If I ever move my ignition over to the new ecm there are a number of built in failsafes that could be enabled without an external relay. I would also gain a 2 step but loose tq mgt but I was thinking about ways to incorporate that back in.

You guys are way to smart for me. LOL. I am going back to my grinding.

LOL ditto.....I usually ask for help from the tech's here at this level

A wastegate and boost controller are a definite option. You would have to spin the blower harder and bleed off excess pressure. Personally, if I was doing a procharger myself, I would do it this way. Smaller pulley would get us into boost sooner.

Wastegate should have a spring in it for boost that would be safe under the fueling of the stock system. Apply pressure on top of the gate with the AEM failsafe controller. Once it detects an abnormal AFR, the system should shut the controller down, reverting back to spring pressure on the gate.

P1X are making some really nice power. Great blower!
