Well ive had my 92 z28 (305) for a few months now and its finally mod time. the previous owner gave me a SLP replacement airfoil but no instructions. i hear its pretty easy to do.

does anyone know where i can find some instructions on the internet or can someone just tell me what to do?

thanks in advance

 

Remove the top plate. Other then that its basically straight forward.

 

installation successful, thanks.

 

I knew you could do it

 

BTW I just remembered when I had one a few years back. SLP had said to put a drop of loctite on the bolt. I cant remember if I did that or not. JIC

 

yeah i put a little on it but it wasn't the high heat stuff, just heavy duty. if necessary i figure i can just put it on later if it gives me any problems.

btw...ill give a little mini review cause i just finished driving it. i think i notice a small difference in power (although i might be a little biased). one thing i definately noticed though was that the motor felt much smoother and had better throttle response.

considering i got it for free when i bought the car, it was definately a good investment.

 

Anybody got any numbers to back up the performance gains?
I'm thinking about making these free mods to my 305TPI and am wondering if I should expect any results in hp or just sound/feel of the engine.

I actually wrote a small program to measure and graph my acceleration times, so I definitely will record acceleration data before & after every single engine mod I do.

 

I don't think it gives you much hp at all if any only thing i noticed was a little better throttle response. If you do a search there is alot about them

 

Be better off filling your stomach at sonic and enjoying the rest of your money.

 

I can easily make one for free so I was curious if it offered any improvements. Throttle response and smoother running sounds good enough to me.

Thanks, guys.
Lou
