Well, my fastest time ever is 15.64 with the weather about 68 degrees, low humidity, no wind, etc. I went to the track on Fri., the weather was exactly opposite. 95 degree temp, 100% humidity, 5-10 mph winds...to say the least not optimal. With the sun still out the car ran consistant 15.80-15.77, but when the sun went down the temp dropped to a freezing 83 degrees and the car began to pick up. I dialed in a 15.72 and I had to get on the brakes hard to stop from running out. I'm not sure what it would have run but I do know that even with conditions that bad, the car would have easily run low 15.6's (I ran my fastest 60 foot ever, a 2.190). My desktop drag 2000 program says that the weather differences would have slowed me about 2.5 tenths so I figure that is about what I got from the Ram Air Box (over an open air filter). All in all, not a bad improvement, I still would like to see the real improvement in ideal conditions.

Hey thanks for posting the results on this mod. I wonder how much better you would do running the 4" snorkle on the drivers side.
Running the stock 3" OE on the drivers side has to reduce performance. I bet it makes a difference if you are able to open up that side. If you ever find one or two of these, put me down for one and I will do the same. Thanks for the e-mail on the install. I am gonna wait till I can find the drivers side 4" snorkle to do this mod...........bob

My305, whats you 1/8mi. time on that run you ran at 2.190 60ft. I ran a 2.215 60ft with a 9.963 1/8im time today. One other thing you might want to consider is changing your plugs back to a single electrode plug to unshroud the spark. You might find another tenth or two.

My 1/8 mile time is a 9.998 at 70.13 mph. I was told that a 4 electrode plug promotes a complete burn, and smoother acceleration, but I could be wrong. They cost enough (6 something a plug X8) so I was hoping they were good. Anyone else think I cold pick up some time going to a single electrode? I just bought the best (most expensive)plug they had, I'm sure there could be better.

Bob...I'm sure if I switched to a 4in driver's side snorkel it would improve the ram effect. I know a guy that works for Chevy dealer and I'm going to see if he can find a 4in snorkel, if he can I'll try to get you one.

My305, with your ignition setup try going back to a stock AC plug and gap then at .045in. If you don't mind changing plugs, there cheap and if they don't show any improvment at least you'll have a extra set of plugs for an emergency. I'd say you will not see any drop off from the plus-4's your running now.

unless you are serious about bracket racing...I would have said the hell w/ it and broke out. This would have proven to yourself what the car really gained.

My305, thanks man for trying on the 4" snorkle. If you get an extra one let me know. I will try also and see what kind of luck I have thanks again.......bob

where did you duct the ram air tubing to, under the car? or behind the head lights like stock?

I saw another post ont this board with pictures of The TPI air scoop/snorkle ducted to a TBI aircleaner. Does anyone know the flow numbers of the TPI scoop/duct work?
It seems that this set up with a single
hose going into a modified TBI aircleaner would be very clean and relatively easy.
The pictures I have seen show the TPI set up used along with the drivers side snorkle,
which I am sure brings in a lot of air but looks a little funky. Just wondering about the flow of the TPI set up...........bob

My305camaro

The ducting goes to the stock location on the radiator support. It mounts in the pre-existing holes (89 and up)

rsilver...do you have an address for that post?
