Either you blower is on backwards or your cam is upside down. /Thread

Man. If I had to deal with as much crap as you have I would have lit my truck on fire.

BTW, I was just sitting in my Tahoe. The mirror temp said 69* the AIT on the Aeroforce gauge said 120*. The truck has been sitting for almost 3 hours. I think the AIT sensors are just out of whack on our trucks.

 

hell about every temperature sensor on these trucks are out of whack my coolant temp gauge says 180 and hp tuners says 160 . and the mirror temp gauges are off to maybe b/c they pick up heat from the radiator .

 

someone asked me what the IAT temp reads with the key on but the engine off after the truck has been sitting all day/night. The answer is: 49* ambient, truck sat for 12hrs, engine temp read 68, IAT read 66.

I spoke to KB yesterday. They said I definitely need to move the air filter which I'll be doing hopefully this weekend. They also said I need to replace my bypass valve. They sell a different one for vehicles with large cams. Something about the spring on the inside being different/removed. It's all over my head but something about the blower building/holding internal boost even and cruise speeds and the new actuator will relieve that boost and in turn reduce heat. Hey, for $100 why not try it.

 

I found a calculation on the KB site. It's accurate.

Theoretical Boost = (((Supercharger size in liters x Pully Ratio) / (Engine L / 2)) x 14.7) -14.7

so for me it's (2.8LX2.416 X 14.7)-14.7=12.24lbs boost
........................3.3

once I eventually change to the 8.5" crank pulley and 3" blower pulley, my pulley ratio will be 2.8. That gives theoretical boost of 20lbs. I think KB says 10hp for every lb boost. That means I'll only make 485+80rwhp 565rwhp.


this is of course assuming nothing else changes and also this is based off of the Mustang dyno numbers from w2w. Cooling **** down, upping timing, fixing the cam, the fixed transmission, etc will hopefully get me into the HP range I was shooting for. 700-750

 

good luck....

 

During the day in the sun it's common for the engine IAT and ECT to be a bit higher than ambient since the underhood temps can raise from the hood absorbing heat. I'd say that's about a normal amount.

 

According to this formula, I should me making 10.77# where I am only seeing 6.5#. Are you actually seeing the 15.5# yours calculates to? I think mine has a lot to do with the restriction at the throttle body. 92mm is next on my mod list. Good news is I should be making 23.7# once I do the 8-rib conversion.

 

oops, i was tired when i did that calculation. No, i see 13 right on the money.

 

Every 10 degrees your intake is cooled is another %1 too, so cool that **** down 100 degrees which is easier for me than with your KB but you'll see another %10.

 

i wish the ****** would stop sur ur ur ur ur ur urging. jesus christ. it stalls now at every stop light and every time i go from drive to reverse or reverse to drive. holy embarrassing. when cruising along if i take my foot off the gas it surges bad too.
