I really could use some direction
Hi Jack,
I really need some advice. I hooked up an smc system and set it for 12 and 20, and still have all 109 race gas in the tank and 22# of boost with reds 93 for the street. I had power logger on the ecm and it showed 218 knock cts for three blasts. Not to mention the car felt like crap. I have a TA49 with 009 and dutt neck an rjc power plate hooker exhaust, THDP 3" and a tin man to the stock maf. The car runs 11.90 but not with this alcohol - everyone swears by it What am I doing wrong? I appreciate all help. Thanks Dan |

I'm not up to speed on the alky thing, but you appear to be too rich.

You could be flooding the engine. I've never worked with an SMC. I had a home built one, but that is what it sounds like to me.
I would try turning the boost down to where you can run without the alcohol. Turn the alcohol off, and make sure everything is running right, then try turning the alcohol on as low as you can get it, and as soon as you are sure it is working, slowly turn up the boost and the alcohol to match.

I had the car running great before the alcohol. Should I lower the fuel pressure? I run 23# of boost and 44# of fuel pressure with red's chip, maybe I need an alky chip??

If the car was running great before the alcohol, then I wouldn't change it. But that is just me. Like I said I haven't used the SMC, but if it was me, I would put it back to where it ran good, turn the alcohol kit on real low, and gradually up the boost and then the alcohol. Take it slow and gradually turn everything up a little at a time.

Thank you for the advice.
I just got two TT chips from Eric and look forward to trying them. As for the SMC I picked it up used and will give it a go. I am using straight denatured alcohol. Thanks again Dan |
