Run a fast 90 or an ls6? Help me choose!
I put mine on back when the car had bolt on and TR224 cammed LS1 with stock heads. Granted I swapped from an LS1 intake to the Fast 90mm but there was no seat of the pants loss anywhere. Around 3500 rpm is where you really felt it come on much harder than stock.
LS6 to Fast will behave similar just not as drastic since the LS6 intake is better than the LS1 right off the bat.

didnt notice entirely too much, more on top end mph wise and now my 36lb injectors are maxed out/duty cycle and need to get my 85mm MAF calibrated better, maybe when thats all nailed down i might notice it more..
FWIW based on your build, and to answer your first question in the post, you WOULD NOT be exceeding the limits of an LS6 intake, however you WILL have some gains over the LS6, as an upgrade.
The Fast stuff needs a lot of messaging in the running air flow/throttle follower tables to get the driveability dialed in. The throttle response is very sensitive on the Fast too.
The LS6 works fine for 90% of the heads cam LS1's, but for those wanting to extract that last bit of power, Fast will definitely make more ponies.

Verdad Gallardo I had a LS6 intake and now have a Fast 92/92 setup...I have done all the work on my car and a good chunk of the tuning.

I think you'd need more than a mail order tune for this to work in my dealings with a FAST 102.
But I'd go with a FAST over an LS6 if you already have it. You can always run your stock TB with an adapter until you can get the car into the hands of a tuner.

I was hoping I'd be able to get a mail order tune close enough to start the car and move it. It's hogging 2 bays lol. I've been meaning to call Frost and ask for his thoughts.
Thats good info, thanks. I'm wondering if I'll even feel a slight low end torque loss through this yank 3600?
Thanks for touching on the tuning and driveability aspect of this. I'm very intolerant of vehicles who lack good street manners. How big of an issue is that with the fast? I plan on a Frost mail order tune, with an eventual Frost dyno tune. From what I've read, he is real good.
To just start and move. Yeah. But no in driving it in traffic. It'll likely stall out.
With that said, Steve is a really good tuner. He may already have a baseline file for the FAST that will help a lot. I now have a couple of a good baselines for the 102 and could probably load a close enough tune for someone without much issue.
