I really like how it's turning out I just wish I didn't have to make a new hood b/c I want to be done with it. Hopefully in about 6 weeks I can call it quits for the year but I need to persevere and stay focused until the hood is completed.
Geezz, I had to look I keep forgetting..they are custom 60mm's built by Brian Bissonette.I missed what turbos you were using.
No EGT's, we were reading plugs and fine tuning the tune with plug readings.We're you logging EGT along with backpressure? Just curious what temps were doing in relation to pressure.
Being a "street" combo things are working out really well and those that helped build the selection of parts said things are falling into what they expected. I'm surprised it wasn't above 2:1 at the earlier 30psi with these 60mm turbos so to make 39psi with this exhaust setup and only be just below 2:1 surprised me. Obviously this would not be a good combo for a full race setup but for a powerful street combo this thing makes a lot of power/torque... Full length exhaust, three mufflers so it's quiet, easy street manners, low stall converter, flex fuel.. I really like it, it's perfect for what I want.It looks like you're getting diminishing returns on increasing the boost to go up 7lbs and only pick up 48 hp?
Also backpressure seems like alot, 2:1 seems acceptable on lower boost levels like 20lbs, but pushing 40lbs of boost, thats nearly 80lbs of backpressure!
Either way nice numbers, better a head gasket than anything else!
Yea, there are a few vids that go into detail so there is info out there. Most race applications go with SST orings in the heads with a receiver groove in the block but at this time I don't plan to pull the block just the heads. I did see that one oring choice is to use a copper oring in the heads w/o a receiver groove in the block so this is what I am researching now.Yea that sounds like a fun street combo, my guess is youre running into head lift at those levels with that setup.
I dont know how many push a 2v setup to those levels, hopefully there are some answers out there for sealing it up and holding it down.
