Turbo Cars/ Exhaust// No Exhaust HP/TQ Gain Loss? Questions

[FinkenS14]

Hey guys I got a question. With my RB Im running open turbo elbow right now, and my question is, am I losing power without running exhaust?
Im paying a buddy off for his 4" exhaust hes selling me, and when its paid, Im putting it on, but till then, am I losing HP and TQ till then?

The way my friend expalined it to me was turbos like hot exhaust gasses, the hotter you can keep the turbine side, the better...hot gasses flow faster then cold, hence more flow and back pressure.

So ya...thanks guys

you want to minimize back pressure on a turbo setup.. the faster air gets out, the better.

that said, you probably wont notice a thing when you install that 4" unless its got bottlenecked resonators

yea 4 inches is pretty massive i doubt you will see any difference.. im sure it will sound like a beast tho

Ya my friend has 4" on his RB26, its insane.

But ya you guys think it cud be casuing fueling issues at all with the o2 sensor being that close to the atmosphere?


Im asking this question because my car runs fine and strong up to about 85% throttle, but once you put your foot all the way down it starts backfiring and shit.

And im almost positive I dont have a vac/boost leak.

Sounds like possibly you are blowing out spark (check plug gap). Possible lean condition? Also o2's really don't do shit @ WOT.

Also i would imagine if you dont even have a downpipe you probably have terrible underhood temps.

No matter what, I recommend installing at least sidepipes if you don't want the full exhaust.

It's not good to dump exhaust gas in front of the passenger compartment.

Even full race cars don't do that.

sucks that you cant afford exhaust get out of the car game bra

Open elbow + backfires = flames in your engine bay = no good.
