Does anyone have an idea on how to route a cold air induction on my motor? The way it is now, it is pulling all the hot air right off the header and valve cover and it is hurting some of my performance. The only problem is that I can't see anywhere to route the tubing for one. Also, I would like to keep the hood I have now, so I would only replace it as a last resort.

Here is a pic to help you see what I am talking about

 

before you go through all the trouble of doing this. is it really going to matter? those ati intercoolers are so effecient, i don't know if it would even make a difference. call ati and ask them. just a thought

 

Binky,

here's my solution, but i had to buy a new hood.



later

nitrobreth, it definately makes a difference. When the motor still has yet to reach full temp the car feels quicker. I think for every ten degrees you loose 1 hp, and if I remember right the metal on the headers reaches something like 600 deg (correct me if I'm wrong). The way it is set up now, all that heat is radiating right up and into the air stream the filter pulls from.

maniacc, that is a very elaborate setup you have. definately something to look into. How much did that cost to fabricate? How much of a difference did you notice after doing that? I also wanted to say thanks for all the help you have provided to me while I have been setting this up. I don't think I have put up one post on this forum you haven't responded to

Thanks again,
Matt

 

Well i recieved alot of help and advice from this board also, it's a great place to be!

Anyway's, the air box was made at Custom Street Dreams and cost about $400, the hood is a Glasstek cost $370+s&h, the paint was alot.
I haven't been to the track with the new set-up, i see about 100*to 140*f intake temps. (temp taken from oem sensor).

My knock retard is lower now too. now i just have to replace the knock sensor with a new one and keep trying to tune-in alittle better.

have fun

If you got rid of the air tube going straight forward and put the elbow straight to the air box and then ran the rest of the intercooler-intake ducting over the AC lines I bet that you'd have room to either build a cold air box to work with your hood or just use the stock TPI camaro intake over the radiator support.

Hell, if you were willing to modify or change the bonnet on the TB I'd make it so the inlet is pointing at least somewhat to the passenger side and you could eliminate most of your bends.

 

Thanks again for the replies guys, and sorry it took so long for me to get back. I just returned from my canoe trip into the boundary waters in minnesota. That was alot of fun, but the black flies are horrible this time of year.

83 Crossfire TA- that is a pretty good idea to turn the bonnet and reduce the amount of bends, I'll have to look at that today. I also don't completely follow your comment with the elbows and my straight pipe. Would it be possible to do a quick sketch in paint or something, because I am definately interested in that idea

thanks again guys,
Matt

 

OK, this is what you've got

 

This is what I meant by moving the elbow to make room

 

and this is what I meant by changing the bonnet to make the whole thing more efficient and make room

 

I ran a 4" 90 degree exhaust elbo (welded) through driverside
fender well,then ran flex tube behind front wheel to below battery tray to an 11" cone filter.
That was worth almost 2 tenths in the 1/2 and then i started to take filter off at the track and run a snorkle off of that for a quick ram air and that was worth a solid tenth.
I dont have a pic from under hood but can get you one if needed
. here is a pic from the out side (have to look very close tho.)

 

Thanks for the diagrams 83 crossfire, that does help alot and is something I will definately look into.

87 TA, if you could get a pic that would be great I think I see what your saying though. I knew that some cold air would make a difference, I'll have to see how it turns out!

Thanks again guys,
Matt

 

Something just came to mind. You could set up something similar to a stock TPI intake & filter setup only at the back of the hood. It would be very similar to cowl induction. Run a tube off of the back of the ATI to the bottom of the windshield. You'll have to make it very thin of course. That's why I was thinking about the stock TPI setup. Just something else to think about.

 

that's a really good idea, and if I do that I won't have to cut up my fender wells!

Thanks ATO monkey!

Matt

 

Maniacc,

Please send me the vendor info on your intake and hood.

Thanks.
