BWK Installed
Well I finally got my BWK installed and was expecting to hopefully maintain power and not get belt slip. Although it seems like its gotten rid of the slip, jury is still out on it since I've only gone wide open throttle about 4-5 times since the car either way feels slower. Not sure if I'm just imagining things or not but I thought maybe not loosing boost because highest I peaked before was 11.4 psi, at least on the dash command app I have. I have to look at it again and make sure if I'm boosting anything higher but the car does feel slower. I don't know how it ended up being that way. The belt I put on was also on of the two belts suggested by VRP so the belt is the correct size as well. Has anyone else had this issue of the car feeling slower after installing BWK?

Is power delivery still smooth? If there's no belt noise and it's smooth I wouldn't imagine the BWK would be causing an issue, but I'd be curious to look at your fuel trims and IAT. Sometimes you fix one issue and it can magnify others...any history of front/upstream o2 sensors or intake air temp sensor?

Ok drove it hard thankfully not a lot of people went to work today. So I hit peak 13psi once and mostly will range from 11.8-12.5 I guess that’s depending on what gear I’m in, not sure but highest boost was in 3rd gear peaked 13psi. So I’m seeing higher boost. I’m thinking maybe the BWK makes it a smoother engagement and it feels slower because it’s not snappy. On a side note since I was looking at the dash command and the IAT’s was showing as well man it drops back down so quick, really quick recovery. Sometimes I’m shocked as to how quick IAT’s climb when your flooring it but now after my secondary heat exchanger I’m just as shocked how quickly it recovers.

After pulley and then after pulley + headers will be better anyhow. Good to know what each mod added. I've got the 80mm and long tubes + full exhaust but haven't had a chance to dyno yet. And I'm wondering what each mod gave individually also, so a good after dyno of yours now with the pulley would help me figure it all out.
