All the drivers at the Deal's Gap Rotary Rally heard this thing.
I was running low boost the whole time.
Nice quiet ride up there, then unleash the beast!

 

ok i was at deal's gap (although I doubt I noticed you among the whole crowd) and i don't get it, call me dense

 

It was louder than the RX-3 (of course he had his baffles in)

It was sweet at full song in the canyons.
I did close it in the parking areas.

 

your exhaust is afro-rigged

 

What is that? Electric cut-out?

EDIT: Just read your sig. I am a jackass.

A buddy of mine had one of those right off the downpipe on his STi. Sounded like a ******* chopper when he opened it. Said he noticed a nice change in power with it open.

 

The rest of the exhaust, including the cat, is factory STOCK!
This whole mod goes in place of the pre-cat.

So maybe you can weld prettier than I

 

lol i know, i was admiring your 80mm to stock conversion.

 

The biggest difference shows in 1st & 2nd gears.

Closed I get 5, 6, 11, 12, 12 PSI
Open I get 10, 11, 13, 13, 13 PSI

 

It's the "I can teach myself how to weld" job done with a hacksaw, a hammer, and a borrowed MIG welder.

 

5 to 10 lbs. in 1st
nice
hows the flames underneath the car??? lol

 

is it over boosting looks like it would

 

The MBC is set for 12 PSI.

Under most conditions the ported waste gate keeps it under 13.

On cold mornings I keep the dump valve closed or it will creep to 14-15.

My ground clearance is 4.5". The exit flange is 3.3"
I suppose if I reved the engine in one spot too long it would melt the tar in the road.
Of course it has to be closed over grass.

 

^ Thats friggin cool as hell. LOL @ melt the tar on the road.

I started getting high boost fuel problems.
I had the boost controller set too high and did a test with the dump open on a cool morning.
The boost spiked and it blew off the FPR hose under the UIM.

The lesson: zip tie ALL the hoses and don't open the dump on cool mornings.

I had been warned - boost is addictive - IT IS!
