Getting my car ready to dyno again in the next few weeks. Sending out my primary's to get cleaned, ditching the clutch fan and gonna bump the boost to 8-9psi.

Is 275whp possible with an intake, full RB turbo back, 720s in the secondarys and the BNR stage 2?

I put down 225whp over the summer on an 85* day, with the clutch fan engaged and the stock primarys

 

did u pull 225 with all those mods or have u put them on since then

the clutch fan isnt stealing much power unless u are making room for an fmic its not really worth the trouble installing the electric fan

 

I made 225 at stock 5.5psi and "dirty" injectors

 

sounds like u could get right around what u are looking for

 

I don't think it should be that hard.

Have you checked AFR's?

275rw with just 720 secondaries sounds a bit scary though.

I'm planning on doing all 720's and a BNR stage 2.

 

AFRs are in the low 12s for safety

 

dynotune? I'm for 250rwhp on low boost for DD on my BNR satge 2 using stock primaries and 720cc secondaries and 255lph fuel pump. According to Brian at BNR, I can go as high as 10psi with my fuel set up but I'm not going to try quite yet.

I might go Digi7ech's route and use 720cc primaries but I want to see how the stock 550cc one do first.

 

I hate the SAFC, thats my only problem. They need to make a damn Rtek 1.7 for the S5 TII.

 

You said you are going to bump up the the pressure? Shouldn't you be running at about 10psi with the RB turbo back kit? I've got one in both of my turbos. My 87 runs 12 psi, with overboost and my 91 runs at about 10 flat.

 

I'M running 8 PSi because I still have the stock S4 NA Mufflers.

 

Ported wastegate on the BNR keeps at 5.5 like its supposed to be.

 

on what turbo? I'm assuming you mean the stock turbo.
If that's the case then it does not apply to the BNR units because the wastegate is ported to ~35mm and we shouldn't see the boost levels you see even with the same setup.
