Good info indeed Jim C.! Thanks.

 

I would not compare an LS1 V8 to an LC2 V6 (GN engine). No generalizations apply. LS2's have horrible heads in comparison to an LS1... and two less cylinders...

One thing to keep in mind...

224/224//112...

224/224//114......... big difference? big difference in overlap?

 

Well John I am glad you wouldn't compare the two but the fact of the matter is that there are several relative issues in that this man wants camshaft advise for a street driven turbocharged car and my point was that if that kind of power could be made with so few cubic inches then more cubic inches should make more power while keeping the car quite streetable and making stupid power for the track. I was also keeping in mind that torque was going to be a major factor for that type of combo. As for the LC2 heads I am sure that Champion heads are far from horrible and flow like gangbusters. The fact that they have two less cylinders has exactly what to do with camshaft comparisons? The point of my post was that small camshafts are not to be ruled out when it comes to making power in a street driven turbo car regardless of C.I.D. How else do you explain Cal's car running 8.50's with 272-c.i.? Hell, Allen Dudley's cars camshaft size or even Mike Marillo's would surprise you. I own and have built numerous turbocharged cars for customers as well as owned a 9.20 turbocharged mustang that still retained A/C and P/S and currently own a 10-sec GN, and a LS1 T/A that I am currently working on a turbo motor for my LS1 using a "small" camshaft but what the hell would I know after 10+ years of working with turbos? A primarily street driven turbo car can make plenty enough power without a ton of duration in the camshaft. The TT LS1 car I saw this weekend only had a camshaft that was just short of 250@.050 and it was an all out track vehicle. Sorry I ruffled your feathers with experience, I will try and curb it in the future if I see you have posted advice. I guess we will have to agree to disagree. Take care.

Jim C.

PS-Why don't you come on down to the next TB BG Nats and let then tell me there is nothing relative between a Turbo LC2 and a Turbo LS1 or even a Turbo 302?

 

Comparing a V6 LC2 to an LS1 makes no sense at all, you really can't string out any generalizations beyond FI tuning how-to's. And I'm sure most of your GN comparos are running like 25-35psi right? No flames here, I like GN's, I'm just saying we need to keep comparing LS1s to LS1s, maybe LT1s, occasionally SBCs, but beyond that I'm not going to advocate comparing the LS1 to any sort of V6 or I6. Or I4. Or I5.

 

my cam came from Mike Brown...i forgot what he trapped with it but i have trapped 142 in the 1/4 (110 1/8) and just recently trapped 112 in the 1/8th. It is a 215/215 114 .567/.567 I did have a 231/226 115 but like this one better for a daily driver and weekend t-n-t.
