Took my SS to the dyno today. was my first time on one. Dyno was a Dynojet.

Results: 285.84 HP
327.03 TQ
Bad thing.... I was getting 11.6* of knock retard at about 4700 RPM according to the Scanmaster. Was hoping to get to 300 HP, but just didn't happen. I'll get the KR figured out and repost the results. Mods are in sig for those interested.

 

How was the A/F ratio?

 

stayed right around 12.5 to 13.0.

 

Not bad for bolt-ons, fix the KR and you should hit 300.

 

thanks. I have a little exhaust leak at the header that needs addressed also. been ticking for a while. could be part of the knock problem. still waiting for the knock module... probably be a while. I hear they are hard to come by these days. got it from GM parts direct. anyone know if they are backordered from them??

 

they are just slow to ship and shipping cost a arm and a leg but other than that they are good

 

Fix the exaust leak. It is probably most of you KR. Low octaine fuel will cause some too.

 

I was running Sunoco 93 in it. I will get on that exhaust leak!

 

Several people have gotten the LT4KM from GMPD in the last few days. I think Summit also has them, now.

 

is it a lt4 knock module or is it a lt4 knock sencer that helps with false knock? thanks and sorry to steel your thead

 

Thats good news. Thanks for that info.

The module is what filters out the noises from the engine. the sensor just sends the signal to the module to decipher whats going on. That's how I understand it.

 

got my knock module today from GMPD. havent tried it on the street for Knock retard yet.
