LT1 TPI TBI Air FOIL

[94GPSHAKER]

Hey whats up I have looked into the camaro forum a lot (I have a 94 LT1 Z28 w/mods) but have never herd anyone talk about air foils i mean they are peobably one of the cheapest significant mods you can do and they are only like 30 bucks for a polished high flow foil. just the foil alone adds at least 50 cfm's and add that with a cold air setup is around a 45 hp 30 tq gain at least that is what i got from it.

I also did some research on turbo kits and i found a poor mans turbo for around 100 bucks that claims to deliver 1200cfm's out of their unit (3psi?!)compared to stock around 850 with cold air mod, I personally am saving for a powerdyne 8psi system for 2500 that would probably give 600 hp to the rear (remote turbo's suck for the price) but for someone who is strapped for cash it looks promising.
heres the link for the turbo it was on e-bay.

That turbo on ebay is a joke. Don't even think twice about buying one of those. As for the air foil, that's just another cheap knock off mod. I mean seriously, a small piece of metal splitting the incoming air can not add 45 Hp. That's more or less just common sense.

Yeah, ebaywise a good thing to know is when it comes to car mods, if it sounds too good to be true, it is. Ive seen "ADD 20HP CHIPS!!!" on there that sell for like a total of 6 bucks with shipping that are simply cheap transistors, a number of people complained about 'service engine" and "reduced engine power" lights coming on and then not going off even after the transistor was removed... I guess it really depends on how much you love your car. I know I wouldnt want to fuck mine up

What mods do you have?

That air foil might give you a couple crank hp at most, from what I understand.

NO WAY IN HELL you can get 45 hp and 30 lb/ft from a cold air, or a cold air with this. Not even close. Maybe... 10 hp? depending on eshaust also...

Yea i know but the air foil does work especially with a BBK 1000cfm Dual 58mm throttle body. oh and uprading to an ss air box w/ functional hood WILL give you an additional 40 hp.

mods BBK 58mm throttle body
pace setter jet headers 1 5/8
high stall tq converter (came with the car when sold to me)
Borla xp stainless duals
had work done to the heads (port polish)
ann arbor 4:10 gears (gm tech installed)
trans mount ,swaybars ,underdrivepully
polished air foil
soon to come powerdyne 8psi supercharger system and comp cams 1/2 inch over cam should put me around 650 hp.
as is 385 hp 380tq (midway drag dyno)

the iat spoof will mess up your comp if you use it with turbo blue
i would never use one or one of those imitator turbos either but some people dont care so that is why i put that link up

maybe it works.. but you're not getting 40 HP out of an intake, SS hoods give about the same increase as a good cold air

[tacoma man.]

them air foils in jegs right now, they are advertised 11 hp and so much torque. you might get 17-20 with a slp cold air intake and the air foil. maybe close to 30 if you slap a better throttle body on from holley.

[blindeyed]

I personally don't see that air foil adding any more hp than you already started with. All it's doing is help directing the incoming air. In a way, it reminds me of that Tornado Fuel Saver that you put in your intake. It just looks and seems like it would add some more power, but doesn't. But that's just me, and I'm just skeptical like that. Maybe if I saw some proof that it does in fact increase overall performance.

There's no way that a Ram Air intake will add 40 hp. Though, it would be nice, it's just simply not possible. The most you will gain from a ram air intake would be anywhere from 10-15 hp. In fact, there won't really be much of a gain from a ram air intake more than there would be a cold air intake. They virtually give you the same performance gain. In order for a ram air intake to give you any noticable gains, you would have to be traveling at extremely high speeds.

define "extremely high speeds"

Well, from what I understand. Ram air doesn't do anything until you hit 120mph. Even then the difference is so unoticeable, and it can hurt the car more than it can help it due to the lowered aerodynamics.

here i will give you a link of a cheap air foil so you know what im talking about http://cgi.ebay.com/ws/eBayISAPI.dll...964364937&rd=1

It really is nothing like that garbage tornado thing.

the air foil is verry userfull if you are planning to get a turbo system because if you know anything about aerodynamics the stock LT1 , tbi and tpi throttle body inlet has flat 90 degree surfaces,the air foil eliminates this thus no friction when the turbocharged air hits the TB also a must for intake dry nos shot because if the nos hits a 90 degree crevice in the tb you cjould have trouble with verry hot backfires and risk blowing the intake manifold.

[LT1MAN]

ive had an air foil, this is what i dont understand:
ok, i had the thing installed with a few other light mods (intake & exhaust) on my last 1994 chevrolet camaro z28 LT1 6speed, it worked pretty good-or good enough for what it costed anyway- a little better throttle response you know. well, wrecked that car and got another 1994 chevrolet camaro z28 LT1 6speed, had the same mods on it when i went to install the air foil. once i installed it on the new car, went to crank it up-ran for about 2 seconds and cut off, cranked again-same thing. tried a couple more times before i took it back off-cranked it up with the airfoil off-ran fine. tried again months later with different mods-same deal. pissed me off severely. still dont understand, the thing is sitting out there in my toolbox collecting dust.

theres no way dude got 30 hp 40 tq blah blah blah whatever --NO WAY IN HELL!

the thing smooths out the airflow, it doesn't increase it, better throttle response not more throttle...

[blindeyed]

I can easily understand an air foil helping to create better air flow through the TB. But i don't see how the air foil can reduce friction by eliminating the 90 degrees in the TB when the thing is made of aluminum. So even if it's sitting in the TB, eventually it will heat up to be just as hot. Thus, it would not eliminate friction at all. I personally wouldn't spend my money on that when a port and polish job can get you just as good results.

i put a air foil on my 91 z with a 350 nitrous motor and felt no difference, the only thing id reccomend before that would be a k&n air filter trust me youll feel more with that then a air foil

[Dober89]

The air foil alone wont really do a whole lot but it definately helps with the airflow. I have one on my tpi engine but I modified the airbox at the same time to increase the air. TPIS has done alot of testing on their air foils. Im not sure what the LT1 throttle body looks like but you can see where the problem is on the TPI throttle body real easy.
