Whats the most anyone has run on stock sleeves(blockgaurded) with management like hondata. As long as it doesnt detonate, The sleeve shouldnt crack right? Well withing reason.

 

well, "cheeze frog" from the Viper vs. DX ran 27psi on stock LS sleeves and blew his motor...so yeah, not 27psi.

he eh he he said cheese frog.

you hear stories of people running 15-20 psi on B or D series motors with good tuning. but id have a spare

 

I've seen several tuned cars running 20-22, but not sure about anything higher than that, and they definitely weren't running that all the time.

 

its not so much a matter of boost but cylinder pressure (which equals HP ultimately)

 

Well i wouldnt be running no more than 14psi..... Plan to get it tuned(hondata) for 14psi and run 12psi street and 14psi track.

Cheesefrog's sleeves gave out at an estimate 575whp with 27psi and nitrous running hondata.

You'll be more than fine with stock sleeves.

 

I dont think boost has much to do with it.. we have been running 20 psi on Shami's stock block guarded LS engine for over a year now.. Cheezefrogs engine blew while running 28psi and a 75 shot. we ran 24 psi on the block for the month prior to the breaking we were making about 575whp with the nitrous before the engine sleeve cracked. That was also with a very aggressive timing map. We will be running 27-29psi on the new stock sleeve block but without the nitrous.

many of my friends run 23-25 on FMU and VAFC only...gsr turbos

 

Hybrid901's been running 19 PSI daily on his car for jeez, a pretty long time, like over a year. Made 374 at the wheels <about 435 ish crank hp> and he BEATS on it every day. Never a sleeve issues.

 

i ran haltech, but eventually the car made 560....stock sleeves. has been running for almost a year and a half...and still going.

 

Again, Hybrid901 is one guy to look to. He's run 20psi+ from a HiFi 60-1 on a non-sleeved block and a Hondata. He made 390whp at 18 or 19psi.

 

Great...so i should have any problem at 14psi if the hondata it tuned right.

 

ralphie from DRT makes over 600 whp on stock sleeves


granted they dont last long...but he makes it

 

ok So if I did Forged Pistons,Rods, Head Gasket, Head Studs and Block Guard? yes or no I should be fine with 15psi daily tuned? and what CR pistons would be good for 15psi if that was the max I was gonna bring it too?

 

Like posted before I made 374whp@ 19psi and never ran less than 16psi. All this on pump gas driven everyday. I put 36,000 miles on it before I changes out the 60-1 hifi to a sc61 and spun a rod bearing 160 miles later.

 

if you want it to last with good tuning the most you can run is about 16 to 18 psi. if you dont care about it lasting long and then want to rebuild it the next month or the next week then run what ever you want.

 

Boost it till it pops!

 

12:1 FMU? What Injectors? What octane gas? Block guard? Thick headgasket?

Just curious.

ok same question but.............. d16 motor?? how far can u go on the stop sleeves with good tuning and the right fuel set up, and hondata or any ems????? i guess im shooting somewhere around 20-22psi max(not daily) and looking for about 350whp or more........can the d16 sleeves take that??

 

uhh 12:1 FMU (pretty sure)
440's
93 octane
no guards
Inline Pro HG...

all built by onlinepro, theyre crazy good people ...

and for D series, i wouldnt break more than 18Lbs on race day with stock sleeves
