LS6, FAST 90,92 or 102??? Recently cracked my lower end on the FAST90. I have to get a new intake, but at this point, I am very skeptical about the 102.
How much power is the 102 worth over a 90, if any?? web links?
I may have to fix my 90 somehow. Are there other options out there?
See engine in sig.

Again pm sweets10v8 he has countless dyno charts on lqs and ls motors. I personally know people running them. Here's a chart vs a stock ls2. Notice the huge gain in tq

I run one, and know how my car went before & after....so I take it you are running a 102 because I know you just wouldn't be mouthing off on just 'hear say' 'aye'
It was a joke man...everyone being so uptight I had to break the tension lol....just trying to make point that there is a point where runner can be less than optimal, specifically on a stock cube motor...that's all i was saying until the ls1tech mafia put a multi thread hit out on me lol...

Within reason more air is never a bad thing.
You have "hard facts" like you posted, while having threads as so: https://ls1tech.com/forums/generatio...78-ported.html
Again we arent being uptight just preventing the spread of bad info. I would absolutely run a 102 all day on my stock internal car. But since I know I can get a FAST 78 for 400 from a friend and that internally they are identical to the 90s, and that I can make it a FAST 85 with nothing more than a dremel I am going to get that. Will I be giving up power to the 102? Absolutely. I am choosing to run the 78 for cost, not because Ill lose all low end which is BS
But see when you say the 102 will gain over the 90 (which is true when it comes to peak power) but you leave out the fact that at minimum the power shifts in the rpm range...I have seen countless tests where a 102 replaces an LS6 and it loses tq in the lower rom range, and while I don't have an experience with the *** dyno I'm not lying either...search Gmhightechperformance and hot rod ls1 cam tests and you will see what I'm describing...(and don't give me the magazine conspiracy theorist comment bc that's a whole other conversation in itself)
