Hello-

I am running a tme evo 8 turbo, i believe that my car is laggy with the boost. I am running 264's @ -2, 3"tbe w/hi-flow cat, 65mm tb, custom 2.325" lower i/c pipe. I have no issue making a decent level of boost or sustaining it.

I have tried a different bov=oem 8 & 9, mbc, tightened the w/g actuator tension some more, verified all boost lines & hoses are tight, put back the oem lower i/c pipe.....

If anyone out there can post a log of boost & rpm, while in 3rd gear, it would be greatly appreciated. in xl, aem data, dsm link, or even a .csv will work

you can also email it to me: anazario@hra.com

Thanks

 

here is my example below

 

Where was this log recorded? You'll be significantly laggier at high altitude.

That log looks normal to me. Full boost by 3500RPM is the norm

 

Hm. I thought it would be earlier with a TME.

I acutally owned an Evo 6.5 TME for a while and it was a laggier then my VIII. I replaced the WG Actuator, thinking that it was the problem, but to no avail. It's a great turbo and has more power potential then the 9.8t but it doesn't spool THAT fast.

You may be more confused by the rediculous claims made by some members here that they see full spool by 2500RPM etc. etc. etc.

YMMV but it's a great turbo but you should get a TME for better transient response and power potential NOT for the "rediculously fast spool".

 

With your setup you should be seeing max boost a lot sooner. Mine has 280's and bigger FMIC and I see 19.5# max at 3100 in 5th and 3400 in 3rd. Are both your intake and exhaust cams retarded to -2? If so, try advancing the intake cam. Is your MBC sourced off the BOV line(a no-no), not the compressor outlet(recommended)? Are you running a HD WGA? FWIW, the JDM MR DV really doesn't hold that well..it vents early, thus slowing spoolup. Better is the Forge RS.

 

I tried a few things today during lunch, retarded ign timing @ lower revs = create more heat to create a turbine effect.

2nd was advancing the intake cam timing from -2 => 0

so i was running 0 int / -2 exh

see plots below

both items were showed improvement, all 3 runs were performed within 30 minutes & all conducted on the same stretch of road.

 

If 0/-2 helped...then +1/-1 may be better still. Are you runnng the stock O2 housing? If so the el cheapo EBay housing should improve spoolup as should ditching the cat(for test purposes, of course). Maybe you should reinstall the upgraded LICP as well.

 

At 0 int / -2 exh, the engine stopped pulling ~7,400, @ -2/-2 the engine would pull very well up to 7,600

I tried +2 / 0 exh, response feels better, but now the engine stops pulling @ 6,800 tops.

I have a complete 3" dp & my lower i/c pip back on as well.

i will post a boost compare later -on

 

Advancing the cam timing on your 264's will help it spool up a bit faster and give you more response down low, but it'll give up almost 10 horsepower up top. If you wanna rev it up over 7500 then you were better off with a -2/-2 or -3/-3 setting. But, really if you want it not to drop off up top(over 6800 RPM), then you need bigger cams.....at least 272's, if not, the whole enchilada 280's. A lot of guys run or have run 280's with the TME @ +2/0 and been real happy. It'll idle like squat, but you'll have tons low end and spoolup plus the 272's or 280's up top are stronger pulling anyway.
