Not bad #'s, and its always something isn't it. That turbo should easily hold 40 lbs or more

 

Close enough indeed!!

 

Yeah. There is def room for more. I just want to see what the air flow upgrades yield me first. We did spike to 37lbs on the dyno.

 

BBK overlay:

 

I agree with you 100%. A nice intake manifold will set you off pretty well, my friend. At least you know where the improvement areas of your build are needed. You have had everyone in suspense and I am glad that the monster is finally tuned with the results to show.

 

You mean to tell me Chris wouldn't hook you up with a rev3 just so you could make your 600 on the dyno? WTF Chris hahaha hook a brotha up on the dyno.

 

that is not bad at all, definitely work on the intake and downpipe and you will see pretty decent gains. The overlay looks awesome. Spool is very close and the EF4 makes quite a bit more power. Awesome!

 

Yeah this looks like an awesome street setup nice choice in mods!

 

I took another look at your parts list, my friend, and I noticed the Spectre air filter. I remember a recent thread that mentioned the "smaller things holding you back". This is the first time I have seen an EVO making the power that you are with this filter. I have typically seen the BR intake kit, Perin, or AEM variants. Have you considered speed density? Just a few thoughts.

 

He is speed density which is why we didn't / couldn't use the Perrin air filter as it wouldn't mate to the 3.5" tubing. It would be interesting to pull the filter off and see how that affects it though!

 

Oh. OK. I did not know that.

 

Should I switch up the filter?

 

hahaha... trust me Chris hooked me up pretty damn huge overall!

 

oh, nice building!

 

installed COP and new 15a fuse.. OMFGBAIBAIWIN11!11111!

Bucking issues gone and throttle is soooooooooooo much smoother.. this ef4 is no joke up top.. I hit 4000rpm and f'n see ya. ALL SMILES.
