Turned up the boost on the silver truck and put it back on the dyno. Gained 90rwhp with just under 5psi boost added. Total boost is now at 18psi and the cheapie intercooler decided it didn't like the extra boost. I was very happy with what it did for now. Getting a bigger intercooler and then turn it up to 25psi

Enjoy the video for now

 

Killer, man it sounded like you revved it to the moon

 

Very nice gypsy!

 

Actually I'm only revving it to 6800. It has a very small turbo cam so it's done pulling by 6500

 

Badazzz!! You think that bottom end will hold up to 25psi?

 

There has been a few people who push them to 25psi so I'm pretty confident this one will too. The motor has really low miles and hasn't had much abuse yet. Also the compression is a bit lower than stock because I bolted on a set of 243 heads and ls9 head gaskets.
Right now the main concern is getting a bigger better intercooler to keep iat's down which will already gain power as well. It's pulling timing for air temps getting too hot so I'm losing a bit of power

 

Cool build!! Does it drive pretty tame?

 

As long as I'm cruising It is very tame but it spools stupid fast and I have to fight traction anywhere under 70-80 mph

 

Did you file the rings at all? 25 PSI is very high. The problem people get into is when the rings butt and break a piston. The stock pistons will shatter sending debris through your turbine. I blew one up at 12 PSI on a supercharged engine with back to back pulls and very high temps. It was my own stupid fault, but when they go, they ruin everything. I'm currently doing an LY6 that has filed rings.

Very impressive video by the way. Looks like a fun ride.

 

Very nice
