Last week I installed the DIY alky kit on my 2.3 turbo on Steve Monroe’s web page and information I obtained from this forum. Absolutely incredible!! Prior to alky installation, I was limited to 20 psi and five degrees of advance. If I added one gallon of tolulene per full tank of gas, I could bump the boost up to 22 psi or so.
I am now running 26psi and 10 degrees of advance with no detonation! Of course, those are just numbers, but a before / after ride in the car really tells the story. It’s a HUGE difference in power. From a low rpm roll in 2nd, the tires break loose when the boost kicks in every time! Other than the big turbo and fuel system to support it, no other mod I have done even compares to the power increase with alky injection. And it only cost me about $120.
I am currently running a 50/50 denatured / water mix and I have the alky turned on at 17.5 psi by the factory overboost buzzer switch. I’m running an M10 jet. I have the pump maxed out (130 psi), and there is no hint of bog, so I am going to try a larger jet. I added a green spray-on LED in the dash connected to the power to the pump motor, and I can see the pump cycling when the alky kicks in. I have a red LED wired to the reservoir, and I have ordered the GM low-level switch to be installed this week. I only have a ½ gallon reservoir, so I am looking for a larger one.
I will continue tuning and adding upgrades to my kit, but just with what I have now, I have achieved a huge increase in performance that I can enjoy every day. This is a great forum, and I only wish I would have done this sooner!
