Ok, while under my car last night, I noticed I have oil leaking from my timing cover. I mention it to my dad and he says, "well I guess we will have to fix it." Then I start thinking, hey, my cam is behind that cover, LOL.

I am going to be running a 150 shot again and was wondering which cam would be the best for a stock headed car. I will most likely add a TB with the swap also.

Which cam would be the best and what are the driving characteristics of both??

 

Even for a spray motor I would go tighter than 114 and for spray I would go with the one with more I/E split.
The 112 most commonly seen for LTX cams is already compromised to account for how most people pick too large a cam but don't want the drivability negatives.

 

224/236

 

Neither, those wide LSA's are not what you want for a setup like yours.

Cams that run n2o do not need a wide LSA, n2o does not make volumetic efficency exceed 100% to create boost....

With 114 n/a the low end will suffer alot, it will bog. I have seen it personal with a friends blower cam, minus the blower.... The reason why 114+ cams move well out of the hole with nitrous is becuase n20 makes ALOT of torque, it makes up for the normal loss of low end power.

110-112 should be more than fine.

 

I am so glad to see others saying this stuff. WAY too many people do the wide LSA, too big cam thing and blindly lead others down the same path. If you want better drivability keep the duration reasonable don't open up thge LSA.

 

For stock heads some of the best cams are CC503, Hot Cam, and CC305. They all perform about the same.

If you plan to do heads later, Id suggest a LE1 or CC306.

On stock heads, there is no need to wind any of these cams past 6100ish RPMs. On decent ported heads, a LE1 should be shifted around 6300ish, and a CC306 may go a tad higher.

Inless you plan long term to spray over a 200 shot, you dont need the wide LSA. For anything under 200, there is realy no need to go any wider than a 112 LSA.

And for any of the mentioned cams above, 918's would make an ideal spring. Sure there are others out there, just saying these would work well and are reasonably priced for what you are getting.

 

thanks alot guys for all the replies. id like to see some more opinions too. I think im leaning towards teh 224/230 with a 112 LSA just because I have heard good things about it and dont want to spin my motor much past 6200

 

The 224/236 112 sure seems to be a solid performer from what I've seen
I'm sure I've seen a few guys makin 345+rwhp with stock heads and this cam.

 

It's a pretty good of the shelf cam. If you want a few more rpm's, a rev kit will help. Mine made peak hp at 5600 and was flat all the way to valve float. It will work decently with a 2600 and up stall although I would recommend a 3200 minimum. If you are only going to spin to 6200, I know frm experience that you will need 150# seat pressure to get there without a rev kit.

 

I have an M6 by the way, so I won't need a stall or anything like that. If it will make the peak power at 5600 then I will just rev it to 6000. I don't want to rev the motor that high since it is a 106,000 mile motor and I don't have the funds for a total rebuild.

 

You dont need a rev kit for that.

Talk to someone who builds engines proffesionally such as SStrokerace

And if you wanted to make more power, you could run a LE1 cam. You would only have to spin it to around 6000-6100 on stock heads. On a good port job, the most you would have to spin a LE1 set up is about 6300RPM's.

This is going to be the cam I am getting once I have sufficient funds for the heads, lifters, etc.

 

I have the 224/230 and I put down 339 at the wheels. With everything in my sig. I like it a lot.

AndyCLT1 - how hard was that K member, Ive been debating one but dont know if I want to go through the hassle. I planned on doing my whole suspension before anything but now that I noticed this timing cover leaking, I think the cam will come first.



How will the LE1 compare to the 224/230 power wise and how will it act with the juice???

 

I ran 12.36@110 with my 224/236 114 GTP4 + bolt ons. I still run it with my SC and it performs well.
