Yes, went with the radical porting on the IM. I know that many here have posted significant improvements with the FAST and if my numbers are lower than expected then I'll give it a shot. I'm not doubting FAST results however, the gains seem to vary greatly from site to site. I've read posts from guys that say don't waste your money, and then I'll read about someone gaining 30hp over a stock IM. Gotta love the web.

I have to second this...the FAST is an amazing mod. I got only 14/16 on the dyno and all above 4500 but the track results were undeniable. I got a very consistent .3 and 3 mph on the track from the FAST.
There are only two downsides to the FAST. 1. Price. If you don't want to spend the money, a ported stocker is a good second choice with good gains though not as good as a FAST. 2. Sound. It's louder than the stock manifold and not such a pleasant sound, a hollow sound around 1600 rpm.

This guy..and the other guy.. and the next guy...
Like I said, just random chatter but not the resounding "consensus agreement".. Hell, I like the thing, just wanted to retain factory aesthetics. Has anyone pulled dyno #'s with the "radical" port work from Peak Speed? I'll post mine after my May 11th dyno date...

You're comparing a late model LS1 that came with the LS6 intake with the upgrade option being a 78mm fast to an LS2 motor with the LS2 intake (MUCH worse than the LS6 intake on the LS1) upgrading to a 90+mm FAST.
The LS6 was a phenomenal intake in stock form.
Totally different situation.

THANKS FloydSummerOf68
FloydSummerOf68:
Thanks for the info!
I plan on getting the FAST 102 ported Intake Manifold, tune + CAI.
I am still shopping around for the best CAI.
My neighbor one block over got water in his engine with the VaraRam. I was just about to make my purchase when this happened to him. I asked if he did anything stupid for this to happen and he said that he was just driving home from work in the rain and must have gone through more of a flooded area than what he felt was too risky and his engine locked up. He has an 05 and bought a rebuilt LS3 motor for it.
I personally think the VaraRam is the best power that is out there.
Do you have any suggestions?
Thanks.

Any open element filter will make good power as long as you're getting ambient air to it.
Get a K&N, Halltech, etc... and prop open the shroud and you'll be set.
There are a LOT of good CAI's out there. Personally I would never put a Vararam on my car due to the poor construction quality.
