112 would carry it out even further, odd they would suggest that. That would peak like 6,800....

All I'm saying is get the EPS lobes... I like knowing I have the newest up to date stuff. And when it come to a cam, it could make a huge difference. They can spec you whatever your little heart desires. Lol

Honestly, I'd hit up Pat G.

Pay him $25, tell him what your plans are, and he'll spec a cam pefect for you. All the guess work is taken out, and he knows his $hit

already PMed him and emailed Texas speed. Thinking Magic stick V3... as long as the car will idle with the AC on in traffic... Screw it I want more POWER!

I'm not trying to knock PatG and his knowledge, because I have learned a lot just from his input here. Although, he is a business marketer! He has teamed up with EPS. He will spec you a cam that you purchase through EPS, either way, it's still a comp cams cam! They claim their lobes are easier on the valvetrain. I have seen no supporting data and they still suggest dual .650" springs regardless. Their ramp rates are crazy identical to the XER lobe which is what the torquer V2 is designed off of. Which is still, a comp cams cam sold though Texas speed.

Patg knows his stuff and has much experience in tuning and messing with different lsa's lifts and durations. His latest cam suggestions are smaller duration by much higher lifts. Up in the .610's! You will replace your springs much earlier with this lift regardless of lobe design. Your ramp rate can't be altered very much when your duration and lift are hard values, that is the reason for my bias opinion of EPS's claim.

The dual springs are mainly to pull that valve back in the seat as quickly as possible to inhibit valve float and eventual piston kiss. With the dual springs, your seat pressures are higher and require a titanium setup for strength. I was warned by my head machinest that the LS valves (non-stainless and tit.) are thin around the edges. Too high of a seat pressure could crack a valve around the seat area. Haven't found any data to support that, but still weary of it.

one this to also remember...the bigger the cam, the more DD unfriendly will be.

A couple of years ago, Geoff Skinner (from EPS) and I sat down with Billy Godbold from Comp and told him that we needed an "endurance" lobe that would make power like an LSL lobe (which makes more power than XE-R lobe), but one that was around .600" lift and could be run with a beehive spring. We wanted a quieter lobe that would have less acceleration and jerk than an XE-R lobe too. The LSG (G for Geoff) lobe was born, but since it is an exclusive lobe for EPS, the lobes quickly were branded as EPS lobes. It was no surprise that these lobes outpowered the XE-R lobes, but it was a surprise that they matched the LSL lobes and sometimes exceeded them (event though they had less lift). The key was valve control. It was flat better. These lobes carrry power higher with less spring pressure.

This is not necessarily the case with an endurance lobe. A lot of what wears out a spring is surge and loss of valve control. An endurance lobe will stay in contact with the lifter easier than a "square" lobe and it's easier on the retainers, locks, and definitely the lifters. The EPS lobes are limited to around .600" lift to balance power and spring life.

A new development has been the new LXL lobe. I asked Billy Godbold from Comp to invent a high lift lobe with a much softer closing ramp rate to reduce valvetrain noise. This is where the LXL lobes come in. An LSL lobe is pretty loud from a sewing machine standpoint. It closes the valves at .009" per degree of cam rotation. An XE-R lobe closes at .008" per degree. An old school XE lobe is a pretty quiet lobe, but it's lower lift. It closes at .006" per degree. The LXL lobe has lift in the .600-.615 range, but it closes at .006" per degree. It's nice and quiet, but it's still a high performer. I like using this lobe for the exhaust on CT-Vs because it keeps the valvetrain quieter. Cadillac refined. Much less sewing machine noise.

Agreed...Another reason to run an endurance lobe. Less spring pressure needed.

The Texas Speed T2 is closer to what I'd run in a CTS-V than a MS3. It's a more balanced cam. I'd just prefer to run it with the newer, quieter, more powerful lobes that I referred to above.

Thanks for chiming in Pat. This is the first I have found any reasoning or explanation behind the claim of a quieter lobe design. I appreciate your wisdom. If you read one of my threads maybe a year ago, I was comparing the ramp rates to the xer lobe and suggesting that the only way to make it less harsh would be to slow down the valve close ramp rate which you have explained is the case. All in all it seems as if the new lobe design is the better half of two lobes into one.


Can you further elaborate as to where the cts-v's specifically should have their tq curve at in reference to weight. I have the torquer 2 and am very pleased with the flat tq curve from 3000 all the way up never fluctuating more the 55 ft. Is this ideal with the heavier platforms?

I have the 232/236 .598/.601 114+3 cam ground on LSR lobes. Biggie if you want a ride hit me up if you wanna make the ride up I may even fill the bottle for ya

We will see. Kinda set on the T2. Unless pat can match their deal w dual springs:pushrods or beat it. He obviously knows what works. And I like his refined power philosophy with the caddie

SNL did a lot of research on their cams to get the perfect tq and hp curve for our fat (4000lb) Vs. This is why I went with their v2 cam over all the others out there.

If you are curious, give SNL a call (817-750-2000) and talk to them about their cams and how they compare to the T2 and others. All supporting valve train parts they sell with their cam packs are from Texas Speed.

Money sent to Pat G to spec my cam. Hope EPS is quick with orders through pat. Want to be installed end of the month.

You doing the install?

Pat G and EPS all have their cams ground through Comp. COmp and them guys engineered the EPS cam lobes so they grind all of their stuff for them. It took me 7-8 weeks to get my EPS cam.

Gonna be having friends install it. Shot that long to get it. Fuxker

Pat G speced cam I shoul dbe ordering today from Geoff. And praying I can get it sooner than what I am hearing.

I know you have your mind set on a cam, have you had the chance to take a Maggied V for a spin? I am in town until Monday if you'd be interested in a teaser.
