I'm not saying those results are not impressive, because they are, but its not a perfect comparison to my car since mine's an A4 with an aftermarket converter. If mine were an M6 car with no WOT slippage I would expect 335hp or more to the wheels. But I could definitely benefit from more intake duration at a minimum, not to mention more on the exhaust side as well.

 

Who did the programming for both you guys?

 

I could email you the dyno sheet if if that's the kind of proof you're looking for.

The owner of the car also responded to this thread-
You could veryify the results with him.

I like the "cadillac" custom grind name.....call it whatever you want, the car moves, pulls strong right up to 6500rpm, has good torque down low, and great driveability....just what I wanted, thanks.....

 

Not sure if that question is directed to me, but I do all the dyno-tuning at Speed Inc.

 

You could always lock the converter the next time you dyno. And just another reminder that there is ALOT more to a camshaft than just the duration/lift #'s.

 

so how much for this cam? stock lifters springs etc? no head work at all ? please email me IM VERY INTERESTED!!

 

I'll post a price tomorrow. (I don't work in sales so I'm not sure on the price).

Stock lifters and pushrods, but the springs/retainers and rocker arms were replaced.

The entire car is COMPLETELY STOCK, except the cam, springs,retainers, rockers, plug wires, muffler, air filter and tuning.

The cam is totally undetectable, until you mash the gas

 

I'd love to see what the dyno looked like... (geoffreychadwick@aol.com)

318hp/320tq to the rear assuming we took a freak factory lt1 with ONLY 10% drivetrain loss, that'd make 256rwhp (it's a 97, so lets say 285 fwhp) that mean between a K&N (5rwhp maybe) wires (what the heck, 5rwhp) and a hooker muffler (which lets say is as effective as a whole cat-back at 10rwhp) which is taking a factory lt1 freak, adding freakishly high numbers for those mods, we're still ONLY talking 276rwhp, which I doubt any lt1 could pull with those mods. Assuming this is similar to a hotcam kit (springs, rockers etc) most hotcam users find up to 30rwhp with tuning. So, with our freak we're to only 306rwhp. Most people also see 30rwhp with more breathing mods then that too... So we're REALLY assuming high #'s for that example.

The Tq isnt really sick, but the HP is. I would hope such a car with a full CAI, headers, and a real catback could dyno upwards of 340hp or perhaps a little bit more.

I dont know enough about cams, but for my car, which I drive a lot and dont want to sack gas milage, the 2mpg loss of the hotcam isnt always something I look foreward to with these gas prices. So here's a cam that obviously dosent have HUGE lsa, but gets great power (like you said, there's more then duration and lift to a cam)

But that factory freak example couldnt come close to what you put together with just a cam package. My concern is gas milage and normal driving (1000rpm-2500rpm) at the moment. I'd love more info, and you've certainly peaked my attention!!!

EDIT: Why the "Cadillac" grind? Is is similar to the northstar specs?

 

I named it the "Cadillac" grind because the car runs SMOOTH with this cam.

It will get better gas mileage and make more power than the hotcam.

It is only 213/218, but remember it peaks at 6,000.


Pricing is-

Cam- $299.00

Springs/locks/retainers- $124.99

If you buy the cam/springs/locks/retainers together subtract $20.

You can also add Comp pro magnum 1.6 self aligning rockers- $264.99

yeah we all know that lift and duration arent as important as intake vavle closing point and total lift area .

i'm not being a smart *** i'm just glad somebody finally proved to them that a small cam with the right ivc point and amount of overlap under .50 would work. its all about optimizing what you've got. the cam i have picked out has quite a bit bigger split than your cam does but maybe i think stock exhaust port is a lot ****tier than it is. now i'm just agrivated that somebody beat me to it

 

Would the 1.6rr/springs/locks/retainers from the Lt4 hotcam kit be enough for this cam's specs?

Is it just me, or is this cam with 1.6rr and springs worth 65 or so rwhp compared to the 30rwhp of the hotcam?

 

INTMD8: Do all the customers have to physically come down to your shop for tuning or do you offer a mail-order PCM programming option for people interested in that cam?

 

I did my programming myself with LT1 Edit, rented an hour on a dynojet with wide band O2 and tuned WOT, part throttle has been from lots of trial and error and driving around logging

I'm just going to go out on a limb and guess this Cadillac cam has a 112 LSA...any tighter than that and idle and smoothness would suffer and emissions would go up a bunch. That being said, a change from 114LS to 112 LS typically only results in a peak HP difference of 4-7 hp on a naturally apsirated engine.

I'm not flaming or doubting but I'm still having a hard time seeing how a basically stock LT1 that may have put down 265 if we're generous with the breathing mod gains picked up 43 hp to the wheels with such a small cam, regardless of what the LSA and lift under the curve is. There are no magic cams, and I would think if this kind of power is possible with that small of duration numbers that Crane or Comp would have figured it out years ago considering this is their business and they've invested tremendous time and money in this stuff.

BTW I'm reading David Vizard's book on SBC Cams and Valvetrains and it is very interesting reading...having to re-read some sections again to fully understand what he's saying.

 

IMO, the hotcam springs/retainers are marginal for a hotcam, and would be marginal at BEST for this cam. The 1.6rr's from the hotcam kit would work well.


I wish I would have got baseline #'s on this car. Most LT1's that are stock with plug wires, muffler, and air filter will dyno about 265rwhp and 300rwtq.

With the cam/springs/rockers alone, the car made 308rwhp because it was a bit rich and hadn't peaked by the time it hit the limiter.

Raising the limiter, dialing in the air/fuel and optimizing timing brought it to 318/320.

So I would say that the cam/rockers/valvesprings/tuning is worth about 50rwhp and 20rwtq.

 

We only do dyno tuning. No mail order. For a mail order tune, I would recommend Ed Wright at Fastchip.
