Title: Aftermarket Air Intake?
Post by: Unofficial on March 26, 2008, 08:27:20 am
Why is it that whenever I go on a website to see which cold air intake will fit my 87 r10 Chevy, It's never an option? The earliest year you can choose is 1988. I know it can be done, so why is there never a kit that specifically fits my truck?

Just to be 100% clear, this is what I'm talking about: (not this exact one)

Thanks in advance to whoever can help.  :)

It was one year only as far as the aftermarket is concerned, so the market isn't out there for them.  In reality the were made from 87-91 in 3/4 and 1 Tons.

Throttle body. I'm a little south of you in Janesville.

And to captkaos, so I just can't have one?  :(

I wouldn't say that, but I don't really see the benefit on any of these other than looks.  We dyno'd a truck before and after and it make no noticeable difference.

You can get some piping and make your own, or you can use a ram-air box.  It should fit the TBI...

i bought one of those 88-95 TBI cold air kits and it fit my truck well.
looked good and thats where it stopped.
it actually choked the motor up a bit.
but i took it off and sold it.
best bet if you want cold air would be a ram air box or similar setup.
heres one i have my eye on.

then just make or buy the piping and snorkle it up to the rad support.

Cool, thanks for the advice. I'm glad I resorted to the site before buying one. I have the stock air box in my truck, but I flipped the lid upside down for a little added airflow. ;)

Alright, I guess I'll just look into one of those ram air boxes. That ebay thing looks awesome.

I'm not much on TBI but isn't the 87 TB the same as 88-95? Wouldn't it be the same mounting configuration?

Could be. I guess I'll just go for the Ram Air box though. I don't want to waste my money on the intake kit if it won't be beneficial.

They are basically the same(I had an '89, and I sold the CAI's),with TBI and FI setups, you won't notice too much of a difference with it...  To really see any type of changes with a CAI, you have to have the Chip Reprogrammed/Flashed for the Increase, or the ECM is going to look at it as a problem, and adjust itself accordingly to correct the problem(Lean the Fuel, Retartd the Timing and Etc. due to the increase of air)...  Unless the Chip has been reprogrammed to compensate for the changes, as stated before, it will seem like it is Bogging/etc...

Carbs take to the benefits of more air easier than a Computer Controled Fuel System, where as a Computer Controled System, the Chip needs to be adjusted so that it doesn't see the changes as possible failures in key areas...

Increase Intake Air Flow, Adjust the Chip.. Increase the Exhaust Flow, Adjust the Chip... Change the Timing too much,adjust the Chip...  Increase the Fuel Flow/Pressure, Adjust the Chip,and So on.....

Most cases you can get away with small changes here and there, but if they add up, or are too much at one time, then adjust the chip for the changes
