Ok so I help a friend put togeather a SI combo that runs rather well I would say and thats not real world proof? You can not port a LS6 intake, it does nothing. A intake can only move so much air period. With that being said thats what limits the top end charge, now when you see a SI car make power till 6200rpm with a ported LS2 that I have never seen happen with a LS6 that tells you one is better than the other. I'm glad you take everything you find in threads as gosple and never try to inovate. You will always be at the back of the pack where you are now.

lilbuddy1587 you always talk about ditch the hassle and slap a FAST then call it a day. I'll love to do that if you will pay up the different between this hassle vs a FAST for me. We're not talking about alot of money, just a range from $250-$625 here which I don't have and I don't wanna spend.

Cost of JUST the intake manifold:
1) UNPORT FAST 90 USED = Average $850 shipped
2) Ported LS6 = $200 + shipping about $225/$625 difference
3) Unport TPiS 90 LS6 = (I've intake about, no modification) = $350 + shipping about $400/$450 difference
4) Ported LS6 w/TPiS 90 mod (I've intake already, no modification) = $200 + $350 + shipping about $600/Only $250 difference your best deal!
5) Ported LS2 (I've to buy a LS2, little modification) = $150 + $275 + shipping about $450/$400 difference

Pick one

Oh, don't tell me if I opt for an UNPORT FAST 90, I've room to grow down the road. The room you're talking about is another $200 that pumps a FAST 90 from $850 up to $1050 easy. Also, that's only that much you can port out. It's not like you mentioned A WHOLE LOT OF ROOM TO GROW. Unless I'm missing something here, other than port the FAST 90, what else you can do to make more rwhp out of it?

Only if I'm lucky enough and find a ported FAST 90 for $950, that's the price I saw most.

One more add-on about the tune. I tuned every single GM vehicle I own from I4 to V8, from compact to minivan (Yes, my Montana is TUNED). So I totally understand what a simple tune can do. However, can you deny the 10 rwhp gain from a ported LS2 intake (according to you 5.7L and 6.0L make no difference in gain)? The ported LS2 intake is about $4.5 per rwhp. Now someone please tell me how much gain from an unport FAST 90 and how much did it cost for 1 rwhp?

Go ahead multi quote me, I'm not trying to argue anything or deny anything. Just to do some experiment and dig out the truth.

Hi.

teke184

iTrader: (5)

basically got my FAST, including throttle body for $900

spent an hour porting it myself with a dremel tool

sold the ls6 intake for $300

$600 for my setup




"1) UNPORT FAST 90 USED = Average $850 shipped
2) Ported LS6 = $200 + shipping about $225/$625 difference"

$850 - $300 for selling the LS6 you say you have = $550...$325 diff

and my home ported FAST made 18hp/12# more power peak, and 5-12hp/torque from 3000rpm and up, including moving my torque peak lower by 500rpm.

this was compared to an LS6 with ported TB....same dyno..same day...tuned for each.

was WELL worth the added $300 or so.

In ur case u already had a ls6 to sell for 300...i don't i would love for someone else close to ohio to come put there fast on my car after i get my ls2 set up on and well see which one make more power thats the only way to figure this out and the same goes for a ls6 intake .......

DID ANYONE READ THE POST ON THE TPIS DYNO RESULTS AND ACTUALL TAKE THE TIME TO SIT DOWN AND COMPARE THESE?!?!?! http://www.tpis.com/index.php?module=2_17_06

Look at intake #4 to #12 ls6 90mm vs ls2

I see alot of BS in this thread & only a few who actually know what they are talkin about when it comes to using a modified LS2 intake. It's very easy to read magazines & repeat it but a whole different thing to actually do your own testing.

I personally lean more toward believing individuals with personal experience & some testing behind their statements vs a magazine.

Ya thxs man i hope some ppl realize they need to look and the results from TPIS intake test ive got the link to a couple post up....its pretty easy to see and none of these intakes are ported and i guess u can't port a ls6, not for sure but i know u can port a ls2 and get results.

Where did I say anything about your "real world proof" being null and void? I didn't. I never said anything about taking threads as "gosple", if that's even a word? How the **** can you say anything about innovation when the LS2 intake has been out for 4 years now and its STILL considered to be complete **** without being gone through? As far as being "at the back of the pack", nice try at another "insult". Didn't realize you had to run 9's and pound your chest to have any knowledgeable input?

"In ur case u already had a ls6 to sell for 300...."

i know...i realize you don't have it, but the person i quoted did. i was refering more to them on what i said.
but YOU can still sell your TB...and sometimes even you ls1 intake. you won't get much, but its something. although that applies to just about any intake upgrade shy of the LS6, since you'll reuse your stock TB.

ANYWAY

"i don't i would love for someone else close to ohio to come put there fast on my car after i get my ls2 set up on and well see which one make more power thats the only way to figure this out and the same goes for a ls6 intake ......"

honestly, if you call around and talk to some shops, you may be surprised what they'll help you with. they may have one sitting around.

the shop that did my FAST comparison cut me one hell of a deal for the tuning, dyno time and even tools to do the swap myself (they got flooded with business the day i came in).

Seeing as how you already have an LS6 intake, why not just go the route that Teke184 suggested?

It doesn't cost $200 to port your own intake. Just takes a steady hand, a little homework and maybe some help from a friend.

There's a lot to be done with the FAST. There's more to it than just porting it. Smoothing out restrictions in areas, smoothing the transitions and if you're skilled enough with plastic work and epoxy, you can re-shape the runners.

There's no denying a possible 8-10rwhp gain from porting both the intake and the TB with a retune. As far as the 5.7L vs the 6.0, thats pointless as both have different heads, cams and air requirements. If anything, the 6.0 would show more of a gain, as it should?

Not trying to argue either but its a message board man. Things can always be misconstrued.


This doesn't apply to everyone but is a good example of how the $$$ comments about the FAST can be thrown out the window in some aspects.

Yea, the LS6 kicks its *** under the curve and in the upper RPM's (5800) the LS2 finally catches up and isn't far off. Don't look at just the PEAK, unless your main concern is the 1/4 mile.

Since you keep referring back to the TPiS test, take a look at this:
http://www.vetteweb.com/tech/vemp_06.../photo_13.html

"GRAPH 4: Stock LS2 Intake vs. LS6 Intake
The LS6 intake not only produced more peak power than the LS2, but it also outperformed the newer-style manifold from 3,700 to 6,500 rpm. We suspect that if the LS6 intake had been configured with a 90mm throttle opening, the difference would have been even more dramatic. Based on this test, it looks like (non-Z06) C6 owners would do well to swap out their factory intake for an LS6 unit. "

Has nothing to do with reading magazines man. It's been 4 years and the LS2 intake still isn't any better. There isn't anything new about it, period. I mean, if it was so good, why is everyone so quick to discard it? You'd think with all of this "testing behind their statements" we'd have a much cheaper/better alternative to the FAST. We don't do we? Discard tests, word of mouth, forums, whatever floats your boat. Information is information, so take it as you will. According to gorilla man, I take everything I read on this god forsaken place as GOSPEL.

I didn't look at just the peak the ls2 is what 4 or 5hp under at some points but than above in some other points and thats unported?? k take the ls6 stock tb size and compare to the ls2 and get back w me LILBUDDUY 1587

you say ohio like its a small place, where in ohio is this dyno we can compare on. i have a ls1 intake on my car with ported TB, and a ls6 laying here for it. if you have a trumped up ls2 we can get down on this for ***** and giggles. oh i have hptuners also and all will be tweaked to there full potental

To all those do home porters, I respect your skill but I won't take a single chance to fxxk up a $300 LS6 or $850 FAST intake. Also, if you home porters are so good, you guys should start doing business like Formato or Cory. Remember, no every single one knows what they're doing nor well experienced. You're not just talking about turn a wrench. If it fxxk up, you're fxxked. Not to mention you're talking about using epoxy to reshape something. That's why there's performance shop, they know what they're doing and I don't. I really suggest you guys start open up your performance shop and get some good business.

This is exactly like aftermarket head vs ported stock cast head. I rather pay TSP $650 to port my head instead of fire up my dremel ended up fxxk something up. And I don't wanna spend double the money for an aftermarket head.

Yes, I've a LS6 intake most likely I'll just send it out to a friend to port it (He works in a machine shop and do porting for living). However, I'm the kinda guy that keep every single piece of stock part, just in case you wanna sell the car and return to stock. When you guys talk about less hassle, selling my stock LS6 and then later looking to get it back. That's hassle right there. Also, please show me the link to where can I get a FAST 90 with TB for $900?
