I need pics to see how to run the plumbing etc. on my iroc. I'am going to put the intercooler in front of the radiator in the grill. Does Skultze have any pics?

 

Check out the page at http://www.skulte.com/turbo.html.

Here ya go for easy links http://www.skulte.com/pictures.html




I've got a Spearco 2-182 core that I'm going to mount in front of the radiator. Its barely too big, so I might section out part of the unibody and weld it back in a little higher. The drivers side turbo will cross over to the pass side where it'll Y together and squeeze past the radiator into the top pass corner of the IC. It'll exit the drivers top corner of the IC and wrap back to the throttlebody. I'm going for 2" to 2.5" piping for each turbo, Y-ing to 3" into/out of the IC. I hope this helps!

Andris, how are you exhausting those things? And do you have the wastegates ran into it if there is an exhaust or is it possibly just a small downpipe off of the wastegate?

 

Askultze
Are you running an intercooler on your car know if so do you have any pics of the intercooler. I was thinking of running the same setup that the red trans am has on your web page. it has the intake come from the front of the car into the TB from the intercooler. I was also planning on building tube headers but not sure what size to make them and whether it matters if the headers are equal or unequal lenghs?

 

How much HP can those banks manifolds support? My goal is 700hp on pump gas@13lbs and 1000hp on race gas@20-25lbs.

 

Sorry for the late reply... I've got the 2.75" turbo outlet necked down to 2.5" dia downpipes (follows similar routing as normal) to a 3.5" Y-pipe, cat shell, and 3" SLP catback. I'd like to make a 3" dual if I can, maybe from ovalized 4" pipe for clearance where you need to. Thats not till after the new motor (i.e. a while)

The intercooler has been sitting on the beer fridge in the garage. I need to quit work and spend more time making fun mods for the Camaro Scavenging for headers isn't a huge consideration since backpressure will be 15 to 45 psi! Volume helps. I'd suggest 1.75" or 1.875" if you want over 800 hp. I love how we can discuss these numbers, and its actually realistic. Frightening I'm shooting for similar numbers (750 hp on street gas), so I guess we'll see when we do. The design is quite ****ty, so tubular headers would be a vast improvement.

I have Bill from speedway helping me and i plan on having tube headers built. Thanks for the pics and info ASkultze, much appreciated. Good luck on your iroc.

 

i've got pics of mine prior to the rebuild at work. email me if anyone wants to see them...
