We are now offering a new cam grind.

On our test car with 9.55' lower, ported blower & TB, New Era, ID 850's and Kooks full exhaust we are seeing 39RWHP gains so far with a shift point of 6500 and a redline of 6800rpm.

Cam specs:

222/238 .602”/.615” 120LSA (-10* overlap = Barry White smooth idle)

This grind uses a new lobe profile that was developed for endurance use and eliminates the sewing machine sound of other lobe profiles.

sounds good...how does this compare to the GT9 cam?

This cam was designed specifically for the LSA with 13.5-15PSI of boost and unported heads. More profiles are on the way for different Mods.

What is an ideal cam spec for ported heads with that same boost range?

Stay tuned. Like KDI said:

Port flow, and disired drivability will dictate "ideal" ... again stay tuned

:histeric:

I love it.

That's pretty smooth...

Question: Have you heard any issues in terms of reliability/durability when spinning the stock blower with a 9.5" lower pulley? I haven't yet, but just asking if you had.

Thanks

What was the horsepower on your test car without the cam?

SC RPM @ 6800 is 21,222 with a 9.55". The Math is lower pulley/upper * RPM. (only 9.6% faster than a stock cam with same pulley)

Test car before was at 578/550RW and 118* IAT2's

My personal car has 36,000 miles on a 9.55" lower @ 80miles a day and upto 117* ambient, reliability is in tune after quality parts choice.

Anymore questions please feel free to ask.

Edit: after re-reading this it sounded short.

that rwhp is about the same as the gt9 which sees 40-45. your lobes look like lsl lobes are they?

Nope LXL :-)

IAT2's were averaging 126* on the dyno its been warm and wanted real world #'s.
