GM maf is "dumb"
What does this mean?
Hey nice pic of that small Tial in there. Looks like plenty of room to the radiator. How is it to the alternator?

GM maf is "dumb"
Dyno Dynamics dynoes read quite a bit lower than a Dynojet. He probably would put down around 470whp on a djet. Put in in that perspective, and i think these numbers look more like what we expect
If you have a thread on your build and results, I will add it to the results thread (unless of course Morphius disapproves), until you get your status changed. If you want.Did you have to run a spacer with this set-up? It's hard to see it in the picture.
I've linked the thread starting at the top. Is that fine until you get some tech posts in?
Definately get those graphs. Peak HP means alot. But seeing the curve to evaluate means alot more since dynos read so drastically different, as you no doubt know.
I'll say it again. You need a bit more timing with your fuel choice and CR. Someone is being conservative. You're not even running stock peak timing. e85 can definately tolerate more. It burns slow. Many with the same manifold temp (same charge cooling and same boost: same adabiatic compression) with similar torque results (similar cylinder pressure), run 22-24 degrees timing advance at peak with e-85 and stock compression.
) basically setup the timing table in the high load area like 2G, but a little smoother/logical. It is conservative yes, on the dyno we never hit any knock, so I know we were no where near the limit.
(but my limit is already reached). So proven status is reached by number of useful tech posts, not just any posts?
I agreee. Using the ECMlink V3 open ecu we (the tuner and I watching) basically setup the timing table in the high load area like 2G, but a little smoother/logical. It is conservative yes, on the dyno we never hit any knock, so I know we were no where near the limit.
I'll try to get the graphs emailed to me, I do obviously have paper copies I could take a pic of and up load(but my limit is already reached).
And yes, thanks for linking the thread.

. Or you can upload the pics to a photobucket account. That works for me.
should have some slips up sunday.
but it works. Good stuff. GREAT results from a dyno dynamics. A dynojet would typically read 22% higher. And GREAT results for only 28psi. Nevermind the 7.8:1CR and 18* timing on e-85. Thanx for the pic of the dyno chart!Agreed on the timing. I'm running 24* 9:1 compression peak timing on e85. With a bws259 .70ar. no knock @ 30psi.
450whp on a mustang dyno. Mustang reads 18% lower than a Dynojet. So that's about 550whp with a dynojet! I want to see another 10 second hx40!!!! Badman21 has already done it. And, kp116 is SOO close.

I'm not even done my twinscroll hx40 build.


Agreed on the timing. I'm running 24* 9:1 compression peak timing on e85. With a bws259 .70ar. no knock @ 30psi. So for sure add some more timing. This guy dynoed on a dyno dynamics and then went to a dyno jet. It was a 16% difference. http://www.dsmtuners.com/forums/turbo-system-tech/330712-bw-s362-log.html So 470 @ 28psi is very good. That turbo will shine @35psi when you turn the boost up and add some timing.
