First,

Let me say I don't have the El-Torro cam. My cam was the "forerunner" of El-torro spec'd by Predator Z awhile back. I wanted something would be smaller than most cams people were running, and with a lot of Tq.

It's a reverse split at 230/228 .612/.588 110-1 that was designed for a cam only car. Well like everyone else, after the cam I wanted more. So I added heads and a Fast 90 setup knowing that I might have to change the cam later to get the full result for the heads.

The heads were Cartek 4x that had been milled to a 59cc chamber. So I did have to flycut my pistons. But after my results, I don't think I will be changing the cam. This setup pulls all the way to the rev limiter, and even looked like it would keep pulling past that if we would have let it.

On to the results..

Here were the cam only results with a LS6 and full bolt-ons.



After Cartek 4x Heads and a Fast 90 setup.

 

wow, bad *** numbers on that reverse split. nice job!

 

That's a kickin torque curve. Who makes the El-torro cam?

 

Those are great numbers from the heads! A4 or M6?

 

It's a M6.

 

Nice,
Not bad for an unconventional cam, Over 350 lbs at 6800 rpm and 340 lbs at 2600 rpm

I think I'm gonna smoke a cigar

rmtt, I want to thank you for proving that thinking outside the box works and for having faith.

You make almost the exact numbers than my 12:1, 224/222 cammed 370 cid.

Good job, I have to say, this setup is

 

Great numbers!

 

Thanks!! I had faith in you.

Look at the jump in Tq between just 3K and 3.5K. It's amazing. And the car drives smooth as silk. It pulls from the moment you step into it until you hit the rev limiter..and the wild thing is that the setup kept carrying with no drop off. I'm not sure how much more it would have went, but I didn't want to spin it any higher. I have head studs, but that's it.

 

Who makes or sells the el torro cam? Thinking about this cam for my car.

 

The El Toro and derivatives are custom grinds on Comp Cam lobes.
I give you the specs and any Comp cam vendor can get it ground.
PM me and we can discuss (I do not charge anything).

 

Those are some extremely nice numbers for a relatively small cam.

 

54 rwhp from a head swap is great. The curve looks to be 30+ rwhp from 3500 with gains steadily increasing.

 

Excellent numbers. What do you figure your compression ratio is?

 

Thanks. A Fast was also part up the upgrade.

 

Not quite sure. But the heads are 59cc chambers, and someone had said 11:1 or slightly more. Th epistons were flycut .050 for the clearance I needed.

 

Thanks. My new motor will be around 11.15:1. Just sort of comparing things.

 

Nice #'s man, you ever calculate what your dynamic compression ratio would be? Any idea what those heads flow?

 

Was the Fast ported too? I wish my X1 had numbers like that!

 

I'm not sure what they flow as I bought them used. As far as DCR, is there a calculator I could use..or if someone could help me figure it out..here are the stats.

The heads are 59cc
I used a stock thickness head gasket
Pistons were cut .050
Cam is listed above.

I do have 93 octane in my area.

 

looking good those cartek 4x heads put down some great numbers...thanks for posting
