Engine/Transmission (1998.5 - 2002) Boost characteristics of ETH w/EZ

[Hohn]

I installed a boost gauge today, but the nylon tubing got a little kink in it. It appears to be ok, but the boost is different then I expected it to be. I guess I am asking: what is normal?



Most of the time, I register no boost until I grab 3rd gear, than i can get some. It maxes out at ~27psi in 5th@high rpm. I also see NO boost under most normal driving conditions. Only when I dip into the fuel do I see it rise. Typical cruise @70MPH I get about 6psi-- just barely off zero. Any kind of deceleration it will dive to zero. The gauge is a 0-60psi Autometer.



I guess this is normal, as it makes sense that the engine will only boost when it's under load. More load= more boost, right?



I just want to see if my install went well, since the EGT didn't (see other thread). Murphy's Law, you know?



I am surmising that I won't see any boost numbers over 25-27ish since I am running around empty.



I tapped the intake horn just under the dipstick (in the back) with 1/8"NPT. Wasn't too hard to take the horn and heater grid assembly off. (have 10mm, will travel



Thanks

That's almost exactly same as mine. I haven't put my boost elbow on, so I max out at about 22psi. I wouldn't worry about it.

 

[Hohn]

Thanks a bunch. I put the elbow on in my case. I just want to make sure the gauge is working right and the kink in the line isn't screwing up my boost readings.



Looks like I am OK. WHEW!!

OK, now that we got the boost question out of the way...



What about a report on the ETH + EZ



Seat of the pants improvment? Ready to terrorize unsuspecting Duracracks and Powerchokes???

 

[Silver]

The EZ made a HUGE difference. :--)



After about two months I got used to it though... . So now I have an AFE and 4in exhaust. I figure by christmas I will have injectors and a clutch :{ This is getting expensive!

 

[DHatfield]

Dane, don't worry the EZ really wakes up the HO even with stock injector and as a bonus the temps (egt's) are still non-issue.

It's a nice drivable package (see sig). It pulls great and as mentioned EGT's are no problem, I've yet to go over 1000'. But I can get some clutch slip if I get on it below 1800 RPM though with the current set up. My largest torque increases are down low according to dyno pulls.
