I am looking for a Sheet metal intake for a T/A A4 LS1, all motor, maybe some NOS in the future. I cant find any of these intakes any where, any one know? And Which intake would be better FAST 90, or a Sheet metal intake?

Thanks

 

Why do you need a sheet metal intake?

 

its more power that a regular intake... etc.

 

according to who?

most of the big number lsx's are running an ls6 style or a carb style intake

 

and at as low as 10% of the cost of a sheetmetal intake too!!! don't waste your money!

 

i had a 382 all bore w/ 78mm LSX intake and TB... on a nitrous setup, but still an all motor tune, it went 118mph

i then put on a beck sheetmetal intake an TPIS 90mm TB on the same nitrous setup, with a nitrous tune for a 200 shot.

same weight, crappier weather, i went 123mph.

i don't care about dyno's, i only care real track time.

and this is a middle range, hydraulic cam'd, 11:1, street setup that it doesn't go above 7000rpm.

for me it worked, and that was an open TB to the engine bay, no ram air type mods. so could it pick up some more than just 5mph?

i don't want to say it'll work for everyone, but it sure as hell worked for me

 

What kind of mods do you have?

 

you cant seriously be comparing the 78mm intake and TB with a 90mm intake and TB can you? i mean after all you do have a 382 and not a 347, the added cubes would require more air. you did also mention you have a nitrous tune with the beck.


I am not trying to bash you and your performance, i am just questioning the effectiveness of a sheet metal intake. Have you performed a test between the beck and a 90/90 fast?
One of the reason i bring this up is the fact that i was going to buy a Sheetmetal intake (i will not name the maker) i taked with several known shops and sponsors on LS1tech in which i was going to have it flowed, ALL of them laughed and stated it was a waste of money because no sheet metal intake out had any impressive flow numbers and that a fast 90/90 had better numbers unported. What was the price difference between a fast 90/90 and the beck? i would be interested in seeing your curve and how it would compare to a similar engine with a different intake.

 

Nope, just giving reference of what happened in MY particular situation.

which is why i put in the last little line

as for the price difference, i was given this intake to try and see if it would work. so my financial investment wasn't a factor.

my thought process is more along the lines of, how much difference is there between a 78mm fast and a 90mm fast? how much actual HP difference would there be do you think? obviously unported vs. unported?

What I was comparing was this when i stated nitrous setup:

3.50 gearing, 4000 TCT stall, 28" tire BUT with a speed inc. dyno tune for the engine.

THEN with the Beck on it, same stuff, but we pulled about 4-5* of timing throughout the whole spectrum for the large shot. should also say to be the most specific, that was also with kook 1 7/8 with the 78mm intake vs hooker 1 3/4 with the beck.

Now i will say, that i've seen better fuel distribution out of the 78mm FAST when reading the plugs. Although it could be attributed to the plate itself compared to a TNT power ring. BOTH entering ahead of the intake, but the front half of the engine(1,2,3,4) were leaner than the rear half with the sheetmetal intake. That compared to most people seeing that 7,8 are the leanest of the bunch under normal circumstances. but now i'm looking at how it performed on spray (127 vs 135 mph on the 100 shots, but again that could be attributed to WAY to many variables)

If I had someone give me a 90/90 to try back to back, I would. But unfortunately I don't have that ability and I spun a bearing in the 382

my biggest complaint is the angle of entry into this specific intake. the TB is angled down as if it's meant for a turbo setup and piping. i'd have to have an S-bend over the front area over the core support, and I'd think that would disrupt flow.

 

that was a great write up.

 

TCI ******* blows.

 

i agree
