I was wondering what is the most compression i can go safely on stock sleeves?
i was told by a relaible source not to go over 11:1.
just wondering what you guys think.
if it matters it is a 95 LS block

Thanks

 

thats some reliable source

 

So how high can i go with a good tuner

 

Fuel is the limiting factor not the stock sleeves.Most people sleeve na blocks for larger displacement or repair.

you can go as high as you want as long as you have enough octane fuel, and a good tuner. sleeves are not going to limit you to compression, but to displacement.

 

im running pump 94 gas right now
so for that type of gas what would be safe
11.5:1???
12:1????

 

I'd say 12.1 should be ok. That is with a good tuner.

 

thats one of the problems
there aren't any good tuners in toronto
thanks for the advice
please still post up how much compression you guys have got on stock sleeves

 

lol dude...stock sleeves doesnt matter.

CR ratio+OCTANE+ TUNE MATTER lol....

i wil be running 13.5:1cr on 94 pump this summer on a 85mm sleeved block, obviously i cant use it to its full potential on pump becuase of detenation. so you take out timing. if you want high CR you need high octane.. which is what i will be doing for the track, having another tune on 110octane, so that it CAN be run to the full potential.

 

i'm running 12.5:1 on my lsvtec 93 octane, hondata good tuner

 

thanks for the input

do some homework dude.

Also, there are some reputable tunners up here that will tune your car safely.

 

like who paul at netronics he blew 2 type r motors from what i heard not to mention what he did to my friends car. he really knows how to run rich but a good guys tho
splitfire, havent heard the greatest things about him. other then the fact that he tried ripping us off
its hard to find a GOOD tuner dude
any suggestions

 

i'd venture to say that in an NA setup cyl pressure is a non-issue for stock sleeves, especially considering that people have made ~500whp on them using FI; you can imagine the cyl pressure on those setups is considerably higher that running, say 15:1 static compression.

if you can't find anyone local whom you trust to tune it, drive down to metro detroit. maybe trailer the car, or have someone write you a basemap safe enough for the ride; then have it finely tuned later. Devin Pearce (formerly at PaynTech, now with AEM) is a very capable tuner. Tom Payn still tunes, and i'm sure that Earl or others at Kinsler injection can help you.

Safely all depends on fuel octane, tuner and engine buildup. The higher cr u go on pump gas with lack of good tuners ur asking for trouble.

IMO 12:1 is ideal WITH a proper tuning.

lol thanks for the info

 

Aside from repair or displacement is there any other reason to sleave on an NA setup?? What about for high RPM? Say 9500-10k?

no, only reason would be for bigger bore...82mm is ok on stock sleeves, anything past, sleeve it.
