I have been browsing these forums trying to gain information to make a decision on what cam I want in my car. I have been going back and forth.
Car is an 02 full weight m6 with 3.89 gears. Full bolt ons and soon to be a cam only car with the occasional 150 hit of juice. street/ strip car..With all things being equal except cam what would the et differance be between a 224/224, .566"/.566" 114 and a 230/238 .600”/.604” 111LSA +4 advance cam be. I understand this is a very very general question with all variables involved. Im thinking that both cams would have peak hp/tq numbers within 15 of eachother. If thats true then wouldnt they both be between .1 or .2 tenths of eachother. I dont want to overcam my car but also dont want to leave a bunch of power on the table. I know the best thing would for me to drive a car that has a cam similar to both and see which one I like better but I dont have that option.... sorry for the rant. Im having a hard time makeing a decision

Have you researched the TR230? Its one of the most proven cams out there for the LS1.

Which TR230 cam were you referring too? Im guessign the tr230/236 .592/.602 112 LSA.. Its close to the 230/238 cam patrick g speced me. It should put up some good numbers. I was also looking at a 228/232 .588"/.595" 110+1
cam.. Im curious as to what people think the differance between the orginal cams mentioned would be.

the 230/238 would really like the spray...

Can anyone name a cam that does not like spray?

the added duration on the exhaust side would be great for spray and my catted exhaust system.

yeah as stated the added exhaust side duration is good for nitrous as opposed to a cam that is matched ex: 224/224 or a cam thats bigger on the intake side, etc..

soo can anybody figure what the 1/4 mile differance could be between the cams

honestly that's not a good question to ask, there are simply too many variables at any given track at any given time, not to mention driver, tune, etc.

buy a desktop dyno/track package program and plug in the numbers and see what it says (just a thought)

While your question is a good one, it is virtually impossible to answer.

I agree you need a 'professional' to analyze your exact setup, gearing, weight, etc..to dial in the exact valve events to get you the overall peak HP/TQ to get you the 1/4 mile times you are looking for.

There are several on this board, but it might require you reach out to them.

Sounds like that 228-232 range is what you are going to need.

Good luck.

The TR 230/224 111 is the cam im talking about. Its on Thunder Racings website. This cam always produces excellent results.

From what I have seen on the tr230/236, I have not been impressed.
