Anybody have any dyno sheets or 1/4 mile times with a TB spacer for the ls1(98-02 birds/maros?)


They are expensive and hell and I think they are total BS..

Prove me wrong and I might buy it!!

Subscribing......not because I want one, but to see if anybody out there can change my mind about these things. I have only heard negative things and that they're a huge waste of $$$.

 

Well, I can't say for sure on these, but they might be relying on the fact that spacers do work on carb'd motors. I doubt anything like it advertised though. I'd be interested to see some results too. I bet you could make a spacer out of some nice plastic and a dremel for pretty cheap if you really wanted to test it.

 

my understanding of these is that they are helpfull on carb/tbi motors due to increasing the plenum volume, and many are made of polymer to resist heat soak in the carb/tb. also they give more room for the fuel to mix with the air, since those two things are combined BEFORE the intake manifold on a carb/tbi.

basically...they would be pointless on an intake manifold design like the ls1. our manifolds are big enough plenum wise, are made out of composite anyway, and the fuel is added just before the intake valve.

- Creates a Vortex of Air

HAH...who cares? the path of the air flow has to turn 90* to enter the runners...what does a vortex do?

- Increases gas mileage up to 5 miles per gallon

HAH HAH...20-25% iincrease in mileage....RIGHT!!

if it did that...don't you think they'd be advertised by every company in the world??

 

I would really like to see some dyno time on these.. moreover some 1/4 mile times..

If I could get 3mpg better outta one of these I would totally buy it... but im throwing up the BS flag... someone wanna sponsor me and let me rent one for a couple months???

 

as i stated, there is very little to be gained from these on the IM design of the lsx.

carb/tbi setup....yes

you won't see a 3mpg increase.

i doubt you'd even see a 3% gain...which is ~.5-.7mpg

a lighter foot will gain you more than that

 

I know.... I installed one from LMC truck on my 88 k5.

but I want to here from someone that has done it...

 

dont waste your money

 

agreed...i have seen them dyno'd on carb motors and make a few ponies.

 

lol. not about to throw down 100 bucks on one. just want to see if anyone has had one dyno tested.

 

I don't see any gain on an Engine that has a MAF Sensor and is EFI, but that's just me..

 

If you want a throttle body spacer, I have one. It's a 90MM and has connections for a nitrous line on one side a fuel line on the other. It probably won't help your mileage, but if you hook up all of the supporting accessories to it, I promise it will gain more than 5hp.

 

lol...

winner

 

$100 says your right.

I used to have a 77 chev pickup w/ 350cid. spacer made differece, BARELY. agreed with the guys. not on FI

 

dont see how vortex would help. wind comming downward would benefit that side. where as wind on the upswing would have to change directions, down!

 

i used to have one.... it makes a cool whistling noise but thats about all its good for

 

not worth the money invest in a new throttle body

 

guy in the ls4 section got 9 hp and 16 ftlb from one we have a restriction right there though thats robbing power

 

I didn't read the posts, but put me down in the "I know for an undeniable fact that these are not worth the money, or any money for that matter" category.
