LS1 intake to fast 102 on H/C LS1?
LS1 intake to fast 102 on H/C LS1? How much would I gain? I still have the stock LS1 intake on my 00 C5 and I am trying to decide if I should sell the LS6 intake I have sitting in my garage and get the fast 102 with an LS2 throttle body.

Going from an LS1 to a FAST would make a huge difference. I would guess somewhere between a 30-40 hp gain, depending on what cam and heads you have.
I've read guys with C5's having clearance issues near the firewall with the 102. You might want to also consider a 92 which would still make a bunch of power and be a little easier to make work.

Stock heads ls6 intake. My car had the above along with a 224 cam and long tubes. It made 395 rwhp and 384 rwtq. Installed a Fast 102 and nick williams t.b.and it gained 7 rwhp and 6 rwtq. Unless your going radical just go with the ls6 intake imo. Hope this helps.
Yea you aren't going to see a 30+ hp increase unless you have heads and cam...if I were you I would just go with the ls6 intake if its a basically stock motor, plus you would need new fuel rails to accommodate the fast 102
Did you even bother to read his post and/or sig to see setup is not anywhere close to a stock motor but is a decent sized h/c setup?

Yeah I think I'll just go with the LS6 that I have. I would be one pissed off mother if I only gained 7hp like chevychase said he did. Plus I have been wanting to go with boost for a while and don't want to have to deal with the sealing issues of the fast.

Either fast intake will give you nice gains now (with a good tune) and will leave you more than enough room to grow.

Some people just can't read. I said the fast intake would work for a radical setup. Isn't this the same as "room to grow"? Yes and ultimately I went radical, 452 rwhp and 401 rwtq. Most people can only speculate what a setup will make, Ive been through the build. Fast 102 intake and t.b. 402 hp 391 tq, ms4 cam and underdrive pulley. 427 hp and 387 tq. , AFR 1530 heads. 452 and 401 respectivley. I really don't think its the tune its just some people are ignorant.

I still have yet to see your point. If you only picked up 7 from an ls1 intake, your doing something wrong. An ls6 intake is worth that or more over an ls1 intake. I could see that being correct if you switched from a 92 to a 102 but not from an ls1. Which is why I say your tune is crap or something else is going on.

You would get my point if you look at the title of my first post you will see I went from an ls6 to a Fast 102 intake not an LS1. It says because I know you can't read for the second time "Stock heads and LS6 intake" in the title and it says "My car had the above along with a .224 cam and I picked 7 RWHP and 6rwtq." Ls6 to Fast 102 for the third time in case you missed it the first and second time.

with your ignorance. And that sucks still. I'd kick your tuner in the ***** or start looking for another problem.
im moving to a fast 92 eventually. i have 241 heads with a full jobber
on em' along with ms3 cam, full valve train, etc... kooks long tubes..
should be able to pick up 20 - 25 maybe ? hope its more than 10

My initial setup did run like ****, which is why I'm building something different. I fail to see the connection between that and your lackluster setup. It's not my fault you have something wrong with your setup that you didn't gain **** with the 102. I'm sure one day you'll figure it out.

My point is Forest is you don't know sh*t and thats all you seem to be able to build. I doubt you could even afford a FAST intake. All you are is someone with an opinion and like a**holes everyone has one. All I tried to do in this thread is save someone some money by giving them some real numbers. I believe my final numbers speak for themselves 452 rwhp and 401 rwtq for an ls1. Argue all you want but most people would agree you could not get these numbers on a bad tune. I can't help this is 300 h.p. more than you've ever been able to accomplish.
Good call buddy. I've forgotten more than you'll ever know about most of this stuff. I've seen setups with half the quality of parts you have making the same power. Hell, a cnc 243 headed ls1 with a smaller cam is making those numbers. Not a number I would be proud of if I had more in the top end than they do in the entire build. Keep dreaming bud.
On a side note, my bum bottom end ls1 made 80 less HP than yours and a shade less torque with cnc 5.3 heads, an ls6 intake and a really shitty tune.
You can badger me all day about the fact I had someone else build the short block because at that point in time I didn't have time between work and school. But you can't hide behind facts, and the facts are you should have gained more with the fast intake.
Your not saving anyone any money by spouting off your terrible results from a fast install, and esp not by suggesting an intake that runs out of breath before the cam is done.
Sorry to bust your bubble but that fast intake is worth more power than you claim. End of story.
