i have a MAPerformance o2 dump, No complaints here.

 

anyone running one of these on a track car? I'm curious what all that exhaust heat from the dump tube does to the underside of the car after a weekend of tracking...

 

I dont see there being a problem, mine comes out at a nice angle with a slash cut tip to avoid spraying the under side of the car. Plus its not dumping on anyrhing but the ground. Hope this helps.

 

Where is the dump tube positioned to exit? Do you have any pics from the underside of the car with it installed? very nice looking piece btw.

 

It takes a 90 off the turbo just like the downpipe and dumps straight at the ground. There should be no clearance issues, and definitely no heat issues.

 

^ Thanks for that. I'm not so sure 'dumping to the ground' won't cause heat issues on a track car, it would need to be piped to exit somewhere outside the car. There are a lot of things under the car that WILL melt from prolonged exposure to 1600* exhaust gasses. \

SOmeone with a track car and external o2 dump chime in please.

 

wow toxic fab dump looks so boss, i need one..

 

how is that heat going to affect anything when it's dumping underneath the car on the ground? It's no hotter than the downpipe itself running right under the engine.

 

Can you still run the stock under tray with the Toxic Fab O2 dump without melting it?

 

I had one customer who posted pics in this thread who wanted to keep the stock under tray with my o2 dump set up, obviously it would fill the under tray up because the dump tube doesn't go past it, so I modified his to have a 2" extension (seen in the pics he posted) and from what i hear it worked out perfect for him and its not melting anything. I would recommend cutting a 2.5" hole (dump tube is 2") for clearance.
Hope this answers your question.

Thanks for all the positive feedback guys I may just add these quotes to our website lol

It sounds like you're considering our full 3" O2 eliminator, great choice The one piece design does make installation and removal a bit tougher but its not a piece that should need to be removed and reinstalled frequently unless you run into some bad luck lol. We do offer a two piece v-band configuration, but only with a recirculated dump due to space constraints.

 

the difference is that instead of dumping exhaust gases behind the car (after its passed thru about 10' of piping and has cooled considerably) you are venting them underneath the front of the car. Doing that WILL eventually melt stuff. ON a track car maintaining heat is a big issue. the last thing you want to do is cook your brake lines, fuel lines, wiring, undercoating, ect.

Still looking for someone with a track car to chime in...

Great point! I'm glad I read this. This may be better suited for a drag car or DD. I bet it would be great if you fabbed up a side exit for tracking.

 

the downpipe opening down to the donut flange does it bottle neck to 2.5?
