[Z06] Katech Torquer LS7 110 vs 116

Burning Brakes
Hi Jason,
I am getting ready to start modifying my BONE stock '08 Z. The initial mods forthcoming are as follows: American Racing Headers w/ x-pipe and hi-flow cats through factory exhaust, Halltech CF112 & beehive, 160* thermostat and of course a custom tune. Which one of your Katech cams would you recommend?
What kind of power can I expect with the above listed mods, cam included?
Thank you
Mike

Yes
~530
1. Interesting idea
2. We did that. It traded ~5hp for 5tq
13:1 compression
E85
FAST manifold
102mm throttle body
I haven't driven the car yet, but idle/drivability should be very good. Jim Hall loves his.
I tried to pick two of the most idential engines for this comparison. Both Street Attack LS7s without ported heads, FAST manifolds, or bigger throttle bodies.

Our car works on the power/weight ratio goal, which we have a 4.2lbs/hp and insane torque. That is a better ratio than the Bugatti Veyron.

Jason,
A couple of guys asked about the dip in the torque curve. Do you think that the FAST LSX-R manifold with the longer runners might smooth this out a little or possibly eliminate it? From what I have seen on dyno runs with the FAST, that seems to be about where it has an advantage over the stock manifold. Have you tried one with the FAST manifold?

I've had the Torquer 110 since April, 2k miles. It rocks. Nearly zero compromise in driveability. Running 25-deg advance at idle, it's difficult to tell whether or not the vehicle is bone stock (from idle quality). Pulls hard off the line, but there's a noticeable seat-of-the-pants increase in torque around 4k-rpm. Revs to the sky smooth and quick. For NA applications, no doubt I'd take the 110 everytime.
Only complaint: I think it should be in the $380-$430 range like every other LS7 cam, especially considering it's manufactured by CompCams. Wasn't enough of a complaint to keep me from buying it though.

Jason,
Have you done any further testing / comparisons with these two cams?
What do you think is happening to cause the dip in torque between 3200 and 4400 with the 110 grind? It's still there with the 116, but not as severe.
Did you try advancing / retarding the 116? I'm assuming the posted dyno run is with it straight up?

We did not sweep test the cam. Often times its installed straight up, but in this test engine for whatever reason it was installed at 110.

Just real quick and simple...The dyno is correcting the horsepower for weather conditions so no matter what the conditions of the day are, we can duplicate the performance from day to day. The baseline for this correction factor is different between the two correction factors.
J607- 60°F, 0% humidity, 29.92 in-Hg baro
J1349 - 77°F, 0% humidity, 29.234 in-Hg baro.

Which injectors were used?
Do the tests with the Fast LSXR use the the stock LS7 fuel injectors with the OEM style fuel rail with spacers? I have some concern that spacers will effect the fuel spray pattern since the tips are raised in the port.

Yes, they did.
