I was talking to a friend the other night who has an RL. I asked him how much boost he was pushing and he said "14 psi". I then asked if he had changed pulley sizes and found out that he hadn't, but that another friend had "done something else to the engine for him." So my question is, is it possible to up the boost without changing pulley sizes? Thanks.

 

Unless the cat is clogged or something... there's no way I know of to raise the boost without changing pullies...

does he even have a boost gauge? Non comp-pkg RLs don't even have gauges.

 

My bet is your friend isn't reading the boost gauge correctly. You'll notice the stock gauge has the numbers 10 and 15 then 3 lines in between. The lines represent 11.25, 12.5 and 13.75....I guess its close...but no cigar

 

I'm not sure if he has a boost gauge. All I know is that his RL is an '04. I should remember this because I did ride in his car once. Of course, I was more concerned with the blue lights behind us...

 

Anybody else have an idea?

 

Well, I found out what they did. Apparently they "disconnected the signal line that opens the bypass at high rpm". Thats how he's making several extra pounds of boost. Could this have some negative effect on his engine over time?

 

...yeesssssssssssssss.... CEL FTW!!!

 

of course you can see more boost without changing pulleys, just port out the blower

 

CAI
porting(SC or TB, which isn't feesable for us)
pully
tune.

Those are the only things I can think of

 

thats called the boost bypass mod...it works.

 

Porting The Blower Is Our Boost Bypass Mod, I Thought It Was More Than That, Idk Which Is Why Im Aksing
