RJC has "vacuum hose"? I didn't see it on their site.

Yes just phone Jason and he will sell you what you need,nice stuff

what sort of hose is it?

Well, in that direction. The Borg Warner turbos have an integral wastegate, and on their solenoid is some really nice hose. Its built more like the intercooler hoses, multiple layer silicone with reinforcement. I think its too small to fit on my fittings, I need to try it.

The generic silicone hoses seem too soft to me.

Bob

Roger that. I've seen that hose before. Some nice stuff. Did you find a source?

http://www.full-race.com/store/turbos/borgwarner-efr/borgwarner-efr-wastegate-hose-kit.html is the borg warner hose,

I think it will be too small (I.D.), I have a small chunk here I need to check.

 

[TurboBob]

this hose looks reasonable also, although not reinforced it should handle the heat better than regular rubber stuff. Just need to figure the best size.

I have hose from Siliconehose.com. Works very good.

Siliconeintakes.com is another great source

I generally use fuel line hose. It works MUCH better. It has fiber braid in it and stays put and stands up to higher temps for longer. For bling, us push lock hose in different colors. (black or blue looks best IMO)

I have also been using fuel line hose. Gives a nice strong fit and is a lot more durable.

 

[TurboBob]

yeah, fuel line is better than vacuum hose, but its still rubber, and you should change it periodically......

I totally agree Bob. I usally check my lines about every 6 months or so. It might be overkill but I am a little crazy like that. You can never be to careful when it comes to your TB right.

I "bent" a HG once too. After 2k miles, we pulled the heads and you could see the exhaust trail on the block side of the gasket but not the head side and the fire ring was still in tact. Glad to see I'm not the only one b/c the guy there couldn't believe it as he was never that lucky in his 20+ year Buick history.

 

[TurboBob]

Well, its much better now.... This is "tuner style" with heavy-wall vacuum hose. I will be upgrading to better hose soon.

Time to put the solenoid back in, 18 psi is pretty lame after having it turned up.. You can also see where the wastegate starts to open.

9.5" converter is coupling pretty well.

 

[TurboBob]

headgaskets seem like they are hanging in there ok......

Hey Bob,

Did the 9.5 lower your wot shift points?

 

[TurboBob]

I think so. Todays blast was the first WOT 2-3 I've done with the new converter. The boost was a bit lower, so its not apples to apples, but it seems like they are lower.

Shift points are based on MPH (the transmission has no idea what the engine RPMs are), so a tighter converter will lower the shift points.

Todays 2-3 was at 64 mph at 5066 RPM (dropping to 4200) a similar test from about 2 years ago showed a 2-3 at about 60mph, and 5800 RPM (dropping to 5300)


(so, yep, seems like it)
