boost limits on stock block

[MikeH686]

Now i have a new question motor is built and done right now its cr is 8.5:1 i was wondering if anyone has gone low compression n/a i want to eventually put a turbo on it but don't have the money in the immediate moments so i look at and think of just putting headers on i know the power wont be there but was wondering if it will affect motor function by going that low at n/a

will be a bit less hp but will be just fine

I ran around on my 327 quite awhile before finally working toward the turbo. It comes in at around 9:1 after figuring the head gasket. No problems and actually put down just over 310 to the rear wheels on a nitrous cam.

Yeah well right now all motor it was dynoing the motor at 410hp

 

[MikeH686]

Not that it makes a difference i was just talking about it being ok and all now the question would be what injectors? I was thinking with the turbo to be at 60# at least thats what the guys at jpc told me so at n/a would 42# be ok? Or could i use the 60s and be at 50% duty cycle?

60's would be fine it just needs to be tuned correctly. I have 160's in my car and it idled at 1% duty cycle with no problems. Buy objectors once, take it from the guy who has bought almost every size they make. Lol

 

[MikeH686]

Ok i saw on another thread that if i put to high i would just be pouring gas out my pipes so 60# it is lol

410 all motor on a stock block....add much boost and BOOM

 

[Gearbanger 101]

Yeah well right now all motor it was dynoing the motor at 410hp

410hp with those mods!?!

I will plan on dropping it to 9:1 or does anyone think lower would be better? I mean I know tuning is key afterwards my setup now is stock bottom end eagle h beam rods probe 10:1 forged pistons custom lunati cam which im gonna change out to either a crane or comp cam edelbrocj performer heads 1.6 roller rockers forged pushrods hollee systemax upper and lower 70 tb with a 74crane it'd 75 maf I can't remember off top of my head

310hp I would believe....but 410hp!?! Something is amiss?

 

[MikeH686]

Hold on let me dig through my build thread i knew i had dyno sheet on there some where

 

[MikeH686]

Yeah my combo has beeb shanged since chit january lol but now its a 347 with-22 dish pistons edelbrock heads with a 3 angle valve job tfs stage one cam scat rotating assembly as well as rods. Holley upper and lower but the numbers were with a 650 carbuerator on it so with the holley it may be a little different but i did dyno at 391 hp with 396 tq
