Did you decide on that ef4 yet? If not you will after I post my dyno sheets

 

yea I already purchased the EF4 and sent off my 9 turbo to them! I'm still waiting on my stroker assembly and I'm waiting on the EF4 to come back to me now.

How much power did you make? And are you on E85 with the Walbro 400? What compression did you go with?

 

took me a minute to find this thread again. why the hell did it get moved?

 

I couldn't find it either.. I didn't even see there was a build section.. haha..

Yep e85\Wally 400 and BAP.. need to break in the engine before tune\back on dyno.

I went with 85.5mm Bore (.020" Over) 9.0:1

I'd be ecstatic with 650hp+ but anything over 600 would be awesome. With prev mods (in sig) I hit 500/440.

 

Nice mod list! Good luck with the build

 

this is a sick setup! anything you wish you could change about the build?

 

Pic and idle vid below. I am on 3rd oil change with AMSOIL break-in oil. About 450 miles until tune

SpoolinUP COP on back order until next week.

 

Ask me in a few weeks...

But prob not.. maybe intake mani and throttle body eventually. And some more engine bay bling.

 

Anxious to see your results with the W400. I am running pumpgas only and have given a lot of though of getting one of these. If you hit 600 on e85 with it, Ill have plenty of room!

 

With a wally 400 he should have no problems with the ef4 hitting 600 whp. I know I have been on the fence as well about getting one.

Love these cams!

 

600 shouldn't be an issue :P

 

Oh and my buddy hit 601 with Wally 400 on his 2g GSX so again I'd suspect you'll be fine

 

Nice build!!

 

Thx. I was able to get another 110 miles in today. So 250 to go before we can tune. Shooting for Fri!
