Im trying to get fesh air to the turbos. Im running two 4" tubes to where the inner headlights used to be so I'll be getting fesh air. The tubes are going to be about 18", and are straight, no bends. The turbos are Tubonetics 62s. My big question is will this restrict any air going to the turbos? Right now Im sucking hot air from under the hood and Im trying to get some cooler inlet temps by sucking fresh air. Im also adding meth kit but I want to get as cool temps as I can right from the start to fully utilize the meth kit.

Well I finished up today, still have to clean everything up. I did end up having to make a slight bend but its still a pretty straight shot. Installed the meth kit, you can see one of the 3 nozzles right in front of the turbo. My next question if what do I do to keep crap from going in the turbos when making a pass? Im guessing a screen or something behind the bell mouths?

Re: Running fesh air inlet tubes to the turbos?

Doesn't sound like it will hurt you any. And the cool air will definately help.

 

Re: Running fesh air inlet tubes to the turbos?

4" tubing on those 62mm won't hurt them breath. What your doing is just fine.

http://www.ramairbox.com/product.html looks like a good setup for what you are doing

 

Added spme pics of the final product. Need to add a screen or something to keep chit out of the turbos now

 

that turned out great. brent made a sticky about how to make a screen for the turbos. it's in the diy forum

 

Looks great. Have you had a chance to run it yet with the meth? Post some more pictures of the engine.

With the licence plate on the front I would assume this is a street car. Looks killer, great job, but why no screening? That could cost a lot of cheddar if something got ingested into the turbo. I am speaking from experience, and it was a costly mistake on my part.

 

Is it best practice to inject the meth into the turbo inlet? I'm no pro but always thought after the intercooler somewhere was better. Could liquid hitting one side of the impeller unbalance it?
Just asking.

 

We found injecting before the turbo and before the throttle body performed the best.

Ran 138 mph this weekend testing with the same boost (7-8lbs), picked up almost 5 mph and .2 tenths with the fresh air and new meth kit AFTER removing the IC
Going to turn the boost up to 18-20 in the next week or 2, pull some timing out see what happens. I'll get some pics of the engine tonight if I can. Nothing special.

 

Man, I had litterally just finished welding everything when I took those pics lol. It has screens on it now. I do some street driving, but not a whole lot. Mostly to the drag strip which is a few miles away and or car shows that are close.

 

The impeller is spinning so fast so will it hurt it? I heard of impeller errosion, what your opinion on that?

Thanks

 

Proaction, do you have a build thread? I have a black '87 SS that will someday get a big single or twins and would love to see your build if you have one.
