What do you guys think could be expected with an LE2 head/cam combo and a Vortech Intercooled system............yes I know that will proabally damage the motor on stock internals but don't worry it'll get rebuilt before it would get any upgrades of the sorts.

 

That cam is definately not a turbo cam. Way too tight an LSA.

 

dont listen to this guy. that LE2 cam will still make power with a blower. Head over to the forced induction area of this site, theres tons of us running cams that people swear "will not work"

 

LE2 Cam - "232/240 .584/.584 108 LSA - 2200-6400 RPM Choppy idle. Good mid range and top end power. Minimum 2800 stall and 3.42 gears for F and Y body. Minimum 3200 stall and 4.11 gears for B body. Comparable to Comp 306 cam."

I did not say it "will not work". I'm saying it's not optimal. And yes for a blower that is used 100% of the time your not helping yourself with a 108 LSA cam(your leaving power on the table). Now I'm sure Lloyd has some LE2.x cams taylored for a blower that I'm not aware of with a more optimal Lobe Seperation. Now those heads on the other hand are great.

 

How much overlap does the LE2 cam have?
How much overlap is too much for boost?
At what boost level does overlap become an issue?
How much boost is the original poster running?

These may be trick questions.

 

i ran a cc306 cam on 6 psi with ported heads and it smoked m/t dr's through 2nd gear. was it an optimal cam, probably not, but with a 112 lsa, it probably didnt hurt much although the duration is on the "big" side for a blower. with a 108 LSA, I would definitely be tempted to swap the cam for a more blower friendly one. just my opinion.

 

my turbo cam is a 108LSA, it was spec'd for my setup, and should work well

 

Your set up seams unique no doubt. I'd be interested to know what it consisted of as far as durations (Adv /.050), lift and ramp styles as far as the cam goes? Also what type of boost levels are we talking about here with that cam and what sort of fuel? Is this a track car that operates at higher rpms(5000-8000) and not necessarily a DD? If so a lower LSA with more overlap ground into the cam is good to get the rpm range desired.

Yes you can work on a custom grind with 108LSA on the steet with little overlap by grinding in less agressive ramp rates to compensate. It's realy all in the ground in overlap. So yes you are right in saying a 108LSA can work and in fact can be good given what kind of set up the OP is looking for.

I guess it would help as far as the OP goes as to whether he is planing on running a track car(5000 - 8000rpms) or a street/strip car(3000 - 6500rpms)? Basically I think Lloyd could come up with a great custom grind for him like he suggests on his web page that would be better than the straight up LE2 cam. I'm not sure what Lloyds Advertised durations are on that cam but it's known they are aggressive thus a 108 LSA on an aggressive lobe tends to lead to a lot of overlap which will get you a real screamer way up top.

Edit: Remember we're talking about a boosted application here not N/A.

 

Yes I think I see what your talking about as those being trick questions. My knowledge on this only extends to extensive research on the issue prior to doing my set up(went a different route - N2O) and the machine shop personel I do business with explaining his work with custom cams on way out there boosted applications with different length headers, etc. etc. Some of that stuff was a little over my head so I'll give your questions a shot based on how I understand them. On three of those to my knowledge unless the OP or Lloyd tells us all the specs who knows? As far as how much is too much overlap? I guess that depends on how high you want to rev that baby.

 

car is:
355 8.7:1 compression
Ported TFS heads
ported LT1 intake
58mm TB (going to probably step up to a single plane and a 90mm setup)
cam is 228/240 .58x/59x

Its really not THAT big of a cam, but i will be shifting around 6800 or so

The car is being built to be a second half of the track car more of less so I can attempt to hook on the small end.
Boost wise, im going for 15 to start it off, probably end up in mid-high 20s

 

have you choose an ecm yet?

 

if your talking to me, right now using an OBD-1 LT1 pcm with a 2 bar SD setup. However, I am looking at switching to an LS1 pcm or megasquirt.
