what will it put down?

 

anyone

 

no one.....

 

465Hp@6500, 407Tq@5500 at the crank

 

I don't think u read carefully. Lol I hope u mean n/a.

But I can say the same setup u just cnc port. No hand port. Smaller valves. Only 10.5:1 compression. No spray. and only on 7 cylinders w a unlocked convertor put down 394/408. I'm hoping this setup does close to 500 n/a

 

And that was at 6700. If you could explain wht ur reasoning for the 5500 rpm peak HP Is. I'd like to know. Maybe I'm missing something??

 

yep..that's N/A at the crank. Get me the full flow table from the heads and I'll get a better number. The numbers are coming from Engine Analyzer Pro 3.9. The more accurate the data, the better estimate you'll get.

 

id say that thing is wayyyyyy off, i made basically those same numbers before. and that is at the wheels. with a much milder setup. i willl have to wait and see

Ok...I re-read your build specs once again. Something doesn't add up...58cc chambers with an .045 head gasket assuming "0" deck height and -4cc pistons does not add up to 11.9:1. It's 11.04:1. Anyway, I tweaked the configuration and used everything you listed. I used a flow table from the PRC website on those heads minus the hand porting.

487HP@6000
474TQ@5000

 

theyre actually 56cc chambers, and why did u figue 0 deck height? its about -.008"

 

Just making assumptions....Ok...It's about 11.6 not going to account for much.When will this motor be done? I am curious to see what the actual numbers wind up being. I've been using EAP for awhile now and it's been pretty accurate.

 

With that setup it should make good power, of course being an auto numbers won't shine like a 6spd car. I bet it runs hard in 1/4 mile tho.

 

any updates?

 

my guess is 605rwhp on bottle

 

well, ive set a goal of 650, on the 175, will have some n/a numbers before the end of next month, and maybe some spray numbers by the end of the year.
