CAMMOTION PERF

Hey Guys. I thought you might enjoy a look at this killer naturally aspirated 627 RWHP 427" C6 Vette that Vengeance Racing recently completed for their customer. Here is a dyno sheet and idle clip:

Impressive. That thing must feel like a real rocket ship from 5K-7K.

Very Impressive indeed! How big is that LLSR cam?

Low 250s intake/Low 260s exhaust and just over .700" lift.

Considering the shape of the curve I was going to say it must have been pretty huge. Nice results. Long term plan is for that setup in my car just with a much smaller cam!

Kinda surprised it doesn't carry better past 7k. I'm sure the intake is the cause but it should be better than the fast up top.

My first thought was "what would 7500RPM look like?!" but that's a lot of cubes and I also figured it was likely running out of air.

How often would these low lash rollers needed to be checked? Ive been contemplating the idea of low lash to drop into my 408 when it gets refreshenedlater on ..been hearing greating things

I have had two in my personal vehicles. I made minor adjustments after break in and then never again. My vehicles might only get about 2-3k miles a year. We have one employee that has 25k on his and hasn't touched it since break in. Kip has one in his Vette that he drives to work every day. He hasn't touched it. I am not sure how many miles on his.

Would these be ideal only for n/a applications or cud it be used with f/i?

Nicely done as always Kip!!!

Absolutely. The American Racing Headers/Farks Supercars Extreme Street Gen 5 Camaro has an F1C94 ProCharger on it. They have won 2 events already this season and won the 2015 LSX Real Street Championship last year.

I'm happy to be running one of Kip's LLSR cam myself.

That thing is no joke. Damn. Those LLSR cams are legit. It is encouraging hearing about people driving them without needing to mess with them.

Why the horrible drop in torque 3500-4500rpm? Is that from the cam or intake?

What coil relocation kit did they use?

I am no wheel dyno expert, but if I had to guess I would think that first little torque surge might be something to do with the dyno's reaction to the initial hit?

I installed a LLSR in mine using shims under the stock rocker arms instead of adjustable rockers and I haven't had to change shims at all after firing it up. There are a couple which are getting on the looser side of the recommended tolerance but not enough to bother them.

They're extremely low maintenance for sure.

First I should say both my LS7 and LS3 engines have Cam motion low lash solid roller spec by Patrick G, these cams rock and top staff is the first time though I see a solid roller heads and cam build where top end came at mayor cost of low end power.

I wouldn't say the LLSR specifically cost low end...I'd say the combo of the heads and cam size sacrificed low end gains. A hydraulic cam of the same size might have had a similar low end curve.

But even then it never makes less power than the blue graph I assume to be a baseline, it just really ramps up hard in the high RPM.
