Anyone ever used them, or heard about the oval porting????

 

i've spent over 2grand with them over the years, very good people, kind of expensive though. I there Mini-Ram and other stuff for our 383 IROC-Z. There mini ram is what the LT-1 was designed off of if i'm not mistaken.

 

i've looked into their big mouth ls6 intakes and the oval TBs.

they are an interesting design, but i've never heard or seen any independant test with them.

just what TPIS got for results....which of course make them seem nearly as good as the FAST for 2/3 the price.

they would definatly be an option if you were really trying for a stealth build w/ stock appearance

 

Got a local guy selling intake and tb for 450.. But its for a vette, so it has the drive by wire stuff. I have a 99 z28....

 

Two independent tests right here for the TPIS Modified 90mm ls6 intake.

Well i have personal experience with it. Last summer i switched my buddies
LS6 intake to the TPIS modified LS6 intake. And let me tell me it makes
a very nice difference. On a M6 you can feel it from 2,000 rpm to redline with NO lose of low end power.It pulls very hard in the mid range. Plus it looks very professionally done.I would definately choose this over the flawed FAST 90 or 92 and i guess next year the FAST 96!!! intake..lol. Or whatever they come up with next.
Bottom line for what FAST charges it should work with almost any setup
without cracking or splitting period. What do you see so many post about
if the FAST is worth it? Why? Cause not alot of cars show more than a 8-10 rwhp gain. Just check out Lingenfelters web site. They sell that TPIS intake
and they used it on a 427cid and compared the FAST 90/90 and the TPIS
intake. Check the site and you'll see that a FAST is not worth spending
even half for what they charge. And also of guys will call people stupid for
installing a stock ported TB that gains an average of 8rwhp for $150..BUT
they'll spend $1400 for the FAST 92 intake, $450 for a 92mm TB and $200 for porting the FAST and gain 15rwhp on average..lol. Thats so screwed up.
Never heard a LS6 intake splitting so the TPIS uses a already proven intake and just makes it better. Sorrry for long reply but no $850 should have the issues and the over inflated gains just so they can justify the cost.
Thats my opinion, but also what i've seen inperson as well.

P.S And the TPIS doesn't crack under boost and it shows gains...FAST doesn't...but it flows better..lol...YEAH whatever
Take care.

 

NJ,
How do you like the TPIS intake? I know when i installed one i wasn't expecting nothing honestly...but man from midrange to 6,500rpm it friggin
works I was shocked....It shows that the only gains FAST got was from
opening the TB opening to 90mm...TPIS proved that. Now Lingenfelter sells
both FAST and TPIS so their test would be a honest test.

 

I am also interested in this intake. I just think it is funny that they also sell fast intakes.

 

BlackNite where in South Jersey are you?? I am near the NJMP race track..

I am 100% completely satisfied with the quality of my TPIS 90mm intake & t.b.
And I am also 100% happy with the dyno results of using the Intake..
My car see's 600 miles a week sometimes and I have probably 30,000 miles on this intake set-up,
I have never had an Issue with how it was modified, constructed and put together...
I used to be a member here years ago when I think it was more commonly used or talked about but I guess it got lost in the mix since most of the newer members seem to want the biggest possible stuff they can fit on their motor..

Me personally I did the research, spoke to a few friends that do this stuff on a daily basis and came to the conclusion since I already had an LS-6 Intake on my car and I was on a budget that I could sacrifice the few extra Hp that the other intake would have provided me,
But come out of the build with almost the same results and saving myself $1000 to put towards a transmission rebuild instead..

Its definitely worth it if you already have an LS-6 Intake..

 

i've read that first article with all the comparisons. but i got the impression it was a TPIS "funded" study, since most of the intakes were of their design.

not exactly what i would call an "independant" test. i could be wrong.

and the lingenfelter test was on a BIG cube motor. isn't exactly apples to apples for most of us lsx guys.


i've been here for 5 yrs, and on cz28 for 10yrs....have yet to see any real threads discussing the TPIS bigmouth intake setups (untill this one). easily could have missed them.

good info though.

but dyno numbers would be nice...not just SOTP

i've been contemplating the FAST....watching for one used and planning to port it myself.

i may look harder at the TPIS setup though

although...you can get the FAST w/ tb for about $1100 plus a little for misc stuff. home porting is free. then sell my ported TB and LS6 intake for $400

not a bad deal for $700-800


although i like the stealth look of the modified ls6 intake

 

I believe at the time of that one test those were the only intakes on the market for LSX cars other than the BBK intake I think..

There was also stuff someplace in the stickies where they flow benched different intakes and discussed or questioned results ot the possibilities of an LS-6 being opened to 90mm or so..

 

I'm in south jersey..about 15 away from philly. Not to far from Atco about 15-20 minutes away. Glad to know you had good luck with the TPIS intake.
I know i was surprised how good it worked, especially from 3,000rpm to top end with zero loss of low end since the LS6 has good runners. Looks like it just needed the larger TB opening Gotta love it.

 

Lingenfelter is one the biggest names in LS motor experience. They aren't
fudge any numbers to make the TPIS look better. I talked with them about
it and they wouldn't steer people wrong. Why do u consider it not independent? Lingenfelter used both intakes on the same day on the same 427cid. And since they sell both intakes and know they can make more money selling the FAST and they still thought it was right for the customer to see the difference between both intakes. Don't get anymore independent than that.

 

I personally seen minor gains with the FAST unless you run a huge cam and heads.
And i hope to go FI in the future so i wouldn't take the chance of the FAST cracking.
Plus the FI guys show even less gains than n/a guys which is strange. If it has a larger
inlet and better runners how can it not work like crazy with boost. Doesn't add up.
There's got to be internal turbulance or a restriction that only FI point out with the extra air mass. It just has too many issues and there's guys running LS6 intakes in the high 10's. I can't find any post on what people gained at the track with a FAST 90/90. One post i saw a guy gain either .5 mph or something like that. For all that money i can use it
in our places and get better gains and keep the LS6 intake on there or maybe go the TPIS route.
