This is very interesting. Keep in mind everyone that the OP has a built engine. The gains probably will not be as much on a stock engine with lower boost levels...

 

True.

The bottom line is higher horsepower and more torque is available for us centrifugal supercharged guys. Just set it and forget it.

 

Yeah would love to see the gains on a stock engine at 10-12 psi.

 

I shall be doing that next week sometime, so I shall report back.

 

Nice! Are you doing before and after dyno?

 

excellent! I also will be doing before and after dyno reads, not on the same day though. probably within the next month or so.

 

Which of you will see the biggest increase in torque and horsepower? Engine details and boost?

 

Not sure. I talked to 06s2k07si about these keys last night. He said the numbers you posted are with a hytech header and the keys being installed on the same dyno pass, is that true?

My setup:
364/222 on a dynojet at King Motorsports in Wisconsin (ambient temp is usually 70 degrees and indoors with the garage doors closed...a controlled environment)
100% stock F20C at 87k miles
RC650cc
NGK 8 series iridiums
SOS 1220SL with 3.2 pulley (approx 11.75-12.25psi)
SOS aftercooler
SOS large heat exchanger
J's racing 70RS
Skunk2 70mm test pipe
ACT HDSS clutch
stock header
stock TB
stock I/M

Next time Im on the dyno Ill have a J's Header, RC750cc injectors, and a 3.0in pulley. Once thats done, Ill be installing teh keys to do my cam timing. keep in mind I have my target AFR at 11.7 WOT.

 

I'm definitely going to get these if the results are good from you guys!

 

It was an all day seven hour session. The car did have the Hytech header on it for the baseline. The runs were all identical conditions with just the cam timing changed.
