Your torque curve falls off quite a bit those last 2000rpms, if you could flatten it out you could find some more HP. Maybe a full 3" exhaust would help with that.

 

yep, greddy kit alright.


did you log the pulls? betcha anything the boost dropped a few pounds by redline....you should look for Ben's EBC table and see what he has to do....iirc redline goes to 100%DC.

 

looks like you're probably losing boost by redline, try a helper spring it helped me

 

Same here. The helper spring would hold 9psi with no boot controller.

 

Think the 3" cat is a restriction?

 

you timming is killing you man

 

maybe a little, but the boost loss is worse.


even if he held 200rwtq to just 5300RPM which it should in the least....peak HP would jump +20 to 200rwhp.

 

So anyone have pics of there spring setup? How many lb spring? I have one but I guess its not strong enough. I just don't want it to be too tight.

How much more timing you think is safe before destination?

 

I'm leaving now.. i should be there in about 30 minutes..

 

Make the spring adjustable so you can dial it up or down a bit.

 

Well dialed in the boost with a MBC and got it stable @ 13-14psi. Thats about 4-5psi higher than the 1st time on the dyno. Went to a different dyno and guess what?

Old #'s



New dyno with 5psi more???



So why is most others with the same setup putting down 230-250 whp?? Where is it? I'm getting frustrated.

I still thinking the "burp" @ 4500 RPM is ignition related. Ordering new coils this week.

HELP!

 

Dyno Dynamics dynamometers (say that ten times fast) are notoriously brutal on the numbers.. Do you have any other logs.. like AFR ?

 

His second plot showed a max of only 189.45hp on a DYNOJET.

 

it's hard to compare numbers on different Dynos is what i'm tying to say but not doing very well.

 

and the 2nd graph has AF and Boost.

 

I'll just duck out now maybe no one will notice.

 

Lol. His numbers should've been higher on the second dyno chart even at the same boost level. 17 percent higher according to Supersaiyan.

 

you guys seem to have really low timing adavance and on the top end. here's my map last time i was on the dyno with my greddy, put down like 244whp uncorrected

 

I may be stupid but it downloaded as a ".vex" file what opens that? Got a screen shot?

 

I think you open a vex with megasquirt. It'll import only the timing table versus importing an entire .msq with all the settings that may not be right for you application.

I love you Mach929.
