Still on the stock short block right?

 

nope built bottom end

 

woh long time no see thread... hopefully be doing some updates to this soon... 400 whp here we come

 

still goin for 400?lol

 

What'd this thing handle on stock engine?

 

haven't changed anything since last time.. i should be damn close to it now .. i'm going for 450 on the dyno but wont drive it with that on the street lol

the stock engine took well over 360 wtrq and 260 whp.. i dynoed that on 15 psi falling to 7 psi by redline on the stock k04.. when it blew up apparently I was seeing 15 psi at redline lol

 

What exactly broke? Rod? wall?

 

Just figured I'd ask someone who's been through it. I haven't been able to find a definite answer. I just upgraded to a stage 2 zzp kit on my '07 le5 and I heard it can handle 300whp and 10-12psi safely but I've also heard 350whp and no more or that 12 psi is pushing it.

 

forgot you had switched to the snail

 

piston had a chunk out of it lol which would be from excessive heat and low end stress

as far as what it can handle.. whp isn't the best way to look at it .. it's heat cylinder pressure and low end trq that will kill your motor prematurely.. and your tune..

as far as only 12 psi.. i had more then that on the procharger and k04... procharger should've been putting down around 320 whp but i never dynoed it properly on 13 psi (highest I got was on 8.5 psi(13 psi pulley but i was having tensioner issues) and that put down 250 whp and 240 wtrq (which was 40 wtrq more then i dynoed it on my 7 psi pulley) and like i said with the k04

k04 dyno

chunk out of piston..(put a nick in the cylinder wall as well.........rawr) I was planning on building the engine anyway so i could feel comfortable with the BNR on the car.. i had 92k on the stock engine lol and 30k of boost

keep in mind on the procharger I was running the car to 7400 on an almost daily basis, on completely stock engine, same thing with the k04

 

Damn so this still runs?

Anyone tune us besides Vince? I really want to put a new trans in my car but I'm losing out on power with his tunes.

 

you gotta get your **** dialed in last you told me you were running mid to high 10s aft.. no one else can do 06 2.2 ions that i'm aware of ..

and yes it still runs getting a brembo swap right now lol.. next is the ported head and cams and hopefully bigger turbo lol 450 whp here we come

 

Good luck with those stock sleeves

 

Bump.

 

interested in this also, would like to know how far I can push my motor before she pops

 

still on stock sleeves....



getting cams, ported head, and moar boost crammed into her soon.... will be easily over 400 whp

 

damn, how much boost is that? thats some awesome numbers man good job. is this built motor +bnr 2871

 

it's a spike of 19 but then only holding 15-16 (hense the huge torque numbers but mediocre HP number)
but yes rods, pistons, valve springs.. and bnr

 

that's alot of boost for stock sleeves, and a **** ton of torque lol. makes me feel better about my motor

 

stock sleeves can hold quite a bit if properly tuned (and don't go apeshit on the boost controller like I did 34psi was goodnight lol) my buddies car was making over 500whp on the stock bottom end with 29psi e85 and a 6262. My motor lasted for years at 400-450whp completely stock at 25 ish psi.

 

I do think that the LE5 sleeves are considerably weaker than LSJ sleeves though

 

probably, but I"ve seen over 400whp on stock le5's also before.

 

yea the top guy for le5's is running stock block .. long as you have a good tune you shouldnt have a problem with sleeves

 

I'm not trying to argue or anything I'm just wondering, but sleeve failures are pretty obviously too high of combustion chamber pressure related failures. So they only way of it being in the tune would be too aggressive ignition timing which is usually what the customer asks for. Even having fueling off wouldn't effect cylinder pressure, if anything a little lean up top would bump egts but decrease cyl pressure from slower flame propagation. So how else would the tune make you pop sleeves?

400whp is pretty crazy, I wonder how long they've driven the car at that power level for. Do you daily your car at that boost elecblue? Really makes me feel good about my motor lol

 

i used to daily my car I dont any more .. but it is always at the boost it made those numbers at though and it regularly sees wot

as far as sleeves... put it this way... lsj's were having issues blowing motors and killing sleeves around 300 when they first came out .... now they're pumping over 400 on fully stock motors
