Hey guys I have an Evo7 with mods of buschur race and piping kit,3" TBE, Buschur intake, Hallman BC, Evo 7 turbo with 10.5 turbine housing, Aquamist 50/50mix. Im not making as much torque I figured the setup should make and the torque is very late compare to everyone else's stock turbo sheets. Can this be my tuning or a boost leak some where ? Im going up to like 275-278 load cell at max boost so i dunno what boost would that b due to these inaccurate boost gauges (25psi ?).
Here is the VDR

No input, guys?

Check your wastegate actuator adjustment. The flapper might be getting held open just a crack. Where are you seeing peak boost? If it's past 4k, it's most likely the WGA.

Thanks . I was thinking the same thing. I might just change it to an evo9 actuator and see if that helps

Report back if it's the culprit :-)

Of course. this is what a forum is for. Can you guys tell me what boost is relative to 275 load?

you dont have a boost gauge??????

I do have an Autometer but I heard most boost gauges are in accurate.

It's hard to say exactly since a boost leak can make the numbers elevated but 'usually' it's about 25psi.

Yes thats true. I need to do a boost leak test ASAP. I know my figures wont b as great as yu guys because my temperatures here in the tropics are 100-106 during the days and in the 90s at nights but I figure the 50/50 with the mods i have should b a little better.Im wondering if i should try 100% meth. What do you guys think?

Not in your climate, I would stick with 50/50. Water has better cooling properties than meth.

I have a Autometer boost guage and JDM map sensor... They booth read the same values(accuarate baby)..

I agree with Jack- WGA is probably open... I did my turbo install and didn't tighten the WGA with a air compressor... So when I would get on it I wouldn't hit full boost till 4.5k or so... Air compressed WGA=28psi at 3100rpm

What do u mean by tighten with the compressor

I have no idea what he is talking about either lol. As for autometer gauges, notorious for being inaccurate from one product to the next. You must have been lucky and got an accurate one. I have seen them off by as much as 3psi at sea level. Brand new out of the box. Always trust the JDM Map Sensor...assuming you edited your evoscan logging formula for your elevation.
