anybody running a 228r combo with a 102 Yea that's about it,anyone running a 228r h/c combo with a 102/102 setup? Or a ported 102 setup,I've seen the 92 combos but since they don't make those anymore.......I'm curious about the 102

What are you looking to validate?
Assuming whether it will make more power the answer is yes.....how much will your car make with it depends on a few dozen variables but the bottom line is a 102 makes more power than a 90/92 because they flow more air and allow the heads to see more net airflow for the engine to process.
Now if we are discussing a ported 90/92 versus an out of the box 102 its a totally different conversation (those results would be similar and in favor of the 90/92 mm ported combo assuming it was ported effectively).
Hope this helps

Having more air to flow will not slow velocity unless there is a design difference in the intakes. The heads determine the velocity in which the air enters the chamber. If anything it would increase the velocity because it's not choking the engines ability to pull air into the chamber.

The 102mm opening at the throttle body has ZERO to do with velocity into the cylinder heads. It's simply a point of restriction for filling the plenum, which the runner feed from.
The 102mm intake simply give you the option to run up to a 102mm TB, but in all reality the 92mm TB is actually adequate for 99.9% of people, but it doesn't look as cool in their sig, so they buy a 102mm TB.
What are you trying to say??

This is the largest misconception with the 102mm intake. Most people don't realize that the runners size, length, shape, taper, etc determine the characteristics of flow, velocity, and useable power band of the intake manifold.

I agree with what I believe thunerstruck was trying to say. I think alot of people look at the 102 (like I did at one point) and automatically think it'd be the best intake for power gains on any LS1 setup regardless of supporting bolt on's. The 102 is expensive, requires full bolt on to truly benefit all of it's potential and really won't do much at all for you without full bolt on's. I guess my point here would be, a moderate setup with a 90/92 can be just as good of a setup depending on the circumstances obviously. People see a 90mm intake vs 102mm intake and get a hard on for the extra air, weather they plan on using it or not.

I had to read what you said a few times, your about 50% right, 50% incorrect.....
He didnt say anything, he quoted me??????
This statement is true, if you have changed your mind you took a step backwards.
Yes it is, see above.....
Completely 1000% incorrect. The FAST has proven itself to show gains on everything from completely stock to crazy. It makes power on everything. It made 21rwhp, without tuning, on my stock LQ9.
I agree, they don't understand that their engine doesn't ask for that amount of air.

Actually.....I was wondering about dyno numbers,I want to run a 228r cam,stage 2.5 ls6 heads,a fast 102 combo and have it ported by Mr. Mamo,just wanted to see if anyone else had this setup or if I would hear "that cam isn't big enough for a 102". Goal is 425 rwhp with an a4. And I've seen alot of the 92 combo numbers,just wanted to see if it was worth it over my ls6 intake.

SweetS10- I meant that I understand the "bigger isn't always better" comment. I've seen threads where people were installing 102's on 95% stock LS1 cars and getting very very minimal gains....around 5 rwhp IIRC. The 102 is a very nice intake, I practically drool everytime I look at it. Bottom line is, it's expensive and requires some modifications to make it fit correctly (from what I've heard). Based on the combo the OP stated, I'm not sure a 102 would benefit him much more than a 90/92 would. Again, just my opinion.
